  • Anthropic’s Alarming Mythos Findings Replicated With Off-the-Shelf AI, Researchers Say

    Anthropic’s Alarming Mythos Findings Replicated With Off-the-Shelf AI, Researchers Say

    In brief

    • Researchers show Anthropic-style exploits can be reproduced with public AI, report claims.
    • Study suggests vulnerability discovery is already cheap and widely accessible.
    • Findings indicate AI cyber capabilities may be spreading faster than expected.

    When Anthropic unveiled Claude Mythos earlier this month, it locked the model behind a vetted coalition of tech giants and framed it as something too dangerous for the public. Treasury Secretary Scott Bessent and Fed Chair Jerome Powell convened an emergency meeting with Wall Street CEOs. The word “vulnpocalypse” resurfaced in security circles.

    And now a team of researchers has further complicated that narrative.

    Vidoc Security took Anthropic’s own patched public examples and tried to reproduce them using GPT-5.4 and Claude Opus 4.6 inside an open-source coding agent called opencode. No Glasswing invite. No private API access. No Anthropic internal stack.

    “We replicated Mythos findings in opencode using public models, not Anthropic’s private stack,” Dawid Moczadło, one of the researchers involved in the experiment, wrote on X after publishing the results. “A better way to read Anthropic’s Mythos release is not ‘one lab has a magical model.’ It is: the economics of vulnerability discovery are changing.”

    The cases they targeted were the same ones Anthropic highlighted in its public materials: a server file-sharing protocol, the networking stack of a security-focused OS, the video-processing software embedded in almost every media platform, and two cryptographic libraries used to verify digital identities across the web.

    Both GPT-5.4 and Claude Opus 4.6 reproduced two bug cases in all three runs each. Claude Opus 4.6 also independently rediscovered a bug in OpenBSD three times straight, while GPT-5.4 scored zero on that one. Some bugs (one involving the FFmpeg library to run videos and another involving the processing of digital signatures with wolfSSL) came back partial—meaning the models found the right code surface but didn’t nail the precise root cause.

    Every scan stayed below $30 per file, meaning researchers were able to find the same vulnerabilities as Anthropic while spending less than $30 to do it.

    “AI models are already good enough to narrow the search space, surface real leads, and sometimes recover the full root cause in battle-tested code,” Moczadło said on X.

    The workflow they used wasn’t a one-shot prompt. It mirrored what Anthropic itself described publicly: give the model a codebase, let it explore, parallelize attempts, filter for signal. The Vidoc team built the same architecture with open tooling. A planning agent split each file into chunks. A separate detection agent ran on each chunk, then inspected other files in the repo to confirm or rule out findings.

    The line ranges inside each detection prompt—for example, “focus on lines 1158-1215″—weren’t chosen by the researchers manually. They were outputs from the prior planning step. The blog post makes this explicit: “We want to be explicit about that because the chunking strategy shapes what each detection agent sees, and we do not want to present the workflow as more manually curated than it was.”

    The study doesn’t claim public models match Mythos on everything. Anthropic’s model went further than just spotting the FreeBSD bug—it built a working attack blueprint, figuring out how an attacker could chain code fragments together across multiple network packets to seize full control of the machine remotely. Vidoc’s models found the flaw. They didn’t build the weapon. That’s where the real gap sits: not in finding the hole, but in knowing exactly how to walk through it.

    But Moczadło’s argument isn’t really that public models are equally powerful. It’s that the expensive part of the workflow is now available to anyone with an API key: “The moat is moving from model access to validation: finding vulnerability signal is getting cheaper; turning it into trusted security work is still hard.”

    Anthropic’s own safety report acknowledged that Cybench, the benchmark used to measure whether a model poses serious cyber risk, “is no longer sufficiently informative of current frontier model capabilities” because Mythos cleared it entirely. The lab estimated comparable capabilities would spread from other AI labs within six to 18 months.

    The Vidoc study suggests the discovery side of that equation is already available outside any gated program. Their full prompt excerpts, model outputs, and methodology appendix are published at the lab’s official site.

  • US Government Moves Bitcoin Tied to $9 Billion Bitfinex Hack

    US Government Moves Bitcoin Tied to $9 Billion Bitfinex Hack

    In brief

    • Blockchain data shows the U.S. government transferred more than $600,000 worth of Bitcoin connected to the 2016 Bitfinex hack.
    • The funds were transferred from a government account to Coinbase Prime, potentially ahead of a sale of the funds.
    • The BTC is connected to the more than $9 billion, or 94,000 BTC which was seized from the Bitfinex hacker.

    Bitcoin holdings linked to the $9 billion hack of crypto exchange Bitfinex in 2016 was on the move Thursday, as addresses connected to the U.S. government transferred around 8.2 BTC to Coinbase Prime, according to data from Arkham Intelligence

    The coins, now valued around $628,000, last moved 2 years ago when a different U.S. government address transferred them to the wallet that was labeled by Arkham as “Bitfinex hacker seized funds.”

    A representative for the Department of Justice did not immediately respond to Decrypt’s request for comment seeking confirmation about the coins’ connection to Bitfinex or why the funds may have been moved. 

    When crypto assets are moved to an exchange, it is often viewed as the precursor to a sale. However, the government’s intentions for the recently transferred BTC remain unknown at this time. 

    The transferred Bitcoin represents just a small fraction of the more than 94,000 Bitcoin seized by the U.S. government as part of its investigation and arrest of Ilya Lichtenstein and partner Heather “Razzlekhan” Morgan for their roles related to the hack and subsequent laundering of stolen funds. Those seized funds are worth more than $7.2 billion now. 

    Lichtenstein, the theft’s orchestrator, exploited a security vulnerability on the crypto exchange that led to the heist of 119,754 BTC—or $9.18 billion worth at today’s prices. Arrested in 2022 on conspiracy to commit money laundering, he later pleaded guilty to the charges in 2023. He was sentenced to five years in prison for money laundering in 2024.

    Morgan, Lichtenstein’s wife and also a rapper, was hit with money laundering charges and later sentenced to 18 months in federal prison.

    Prior to sentencing, the pair reached a plea deal with prosecutors in 2023, agreeing to forfeit all the remaining proceeds from the nearly 120,000 BTC that was taken from the exchange. 

    Lichtenstein and Morgan were both recently released from prison, crediting President Trump for their early release despite there being no official reported action from the president to commute the sentences. 

    “I want to give a shoutout to Papa Trump for making my 18-month sentence shorter,” Morgan said at the time. “So razzle-fucking-dazzle.”

  • Strategy Shares Pop as Bitcoin Holdings Flip Green, Near $61 Billion

    Strategy Shares Pop as Bitcoin Holdings Flip Green, Near $61 Billion

    In brief

    • Strategy shares jumped 10% to $164 on Friday after Iran declared that the Strait of Hormuz was “completely open” to commercial ships for the remainder of a 10-day ceasefire between Israel and Lebanon.
    • The Bitcoin-buying firm’s stockpile showed gains on paper for the first time since early February as Bitcoin bounced to $77,200.
    • The crypto market’s weaker price momentum and lingering investor caution remains concerning, according to IG Group’s Alex Rudolph.

    Strategy shares surged on Friday as cooling tensions in the Middle East and Bitcoin’s ensuing rally propelled the firm’s massive digital stockpile back into the black.

    The company’s stock price had jumped 10% to $164 by 1:30 p.m. Eastern Time, according to Yahoo Finance. The Tysons Corner, Virginia-based firm saw shares soar above $173 earlier in the session, marking their highest peak since mid-January.

    Bitcoin had climbed 4.1% over the last 24 hours to trade near $77,200, according to CoinGecko. After accumulating nearly 781,000 Bitcoin at an average price of $75,577, Strategy saw its $60.5 billion bet thrust into the green for the first time in three months with the move.

    The shift likely offered a reprieve for Strategy co-founder and Executive Chairman Michael Saylor, whose firm—the world’s largest corporate Bitcoin holder—had been under fire as paper losses ballooned into the billions as the asset dipped to $65,600 this year.

    “Bitcoin and chill,” Saylor said in an X post on Friday, sharing an apparently AI-generated image of himself lounging shirtless on a luxury yacht in a pair of orange shorts.

    Friday’s bounce followed a declaration from Seyed Abbas Araghchi, Iran’s foreign minister, that the Strait of Hormuz was “completely open” to commercial ships for the remainder of a 10-day ceasefire between Israel and Lebanon that took effect late on Thursday.

    Strategy shares were on track for their best daily performance in over a month, a move that “highlights just how sensitive these names are to shifts in broader risk sentiment, rather than purely crypto-specific drivers,” IG Group Market Analyst Alex Rudolph told Decrypt.

    Easing geopolitical tensions may have prompted a return to risk-on positioning; however, Rudolph said that a short-term boost does “not resolve the underlying pressures facing crypto markets, including weaker price momentum and lingering investor caution.”

    Strategy shares remained down 42% from $279 over the past six months. The company’s tumbling stock price raised questions last year about whether Bitcoin’s price could become further depressed if Strategy were forced to pare its holdings amid the rout.

    For some, those fears have been heightened by Strategy’s embrace of STRC. As the company has doled out billions of dollars worth of the dividend-paying product, the firm has become saddled with additional costs for the foreseeable future.

    On Myriad, a prediction market owned by Decrypt parent company Dastan, traders foresaw a 13% chance that Strategy would sell Bitcoin this year. Around the time that Strategy’s holdings turned negative in early February, they penciled in a 30% chance of sales happening.

    “Because they have such a large stockpile, they are starting to become a gorilla that can move the market,” Bitwise Senior Investment Strategist Juan Leon told Decrypt. “It adds more psychological pressure to the downside than to the upside, because the worry for investors becomes ever greater when they’re underwater.”

    Strategy’s average purchase price may represent a key threshold from the perspective of  investor sentiment, but Leon also pointed to the $76,000 mark as the realized holder price for individuals betting on Bitcoin amid the broader market.

    “I think we really have to hold that level and continue trading above it to really feel that this rally can have legs,” he said. “Otherwise, if we stay below it, I think this is just a dead cat bounce.”

  • Circle Hit With Class Action Lawsuit Over $285M Drift Protocol Hack

    Circle Hit With Class Action Lawsuit Over $285M Drift Protocol Hack

    In brief

    • Stablecoin issuer Circle is facing a class action lawsuit from Drift Protocol investors who lost money in a recent $280 million exploit of the DeFi protocol.
    • The suit targets Circle’s handling of the exploit, alleging that hackers moved stolen USDC through the firm’s own cross-chain infrastructure.
    • Circle has defended its actions, saying it only freezes assets when legally mandated to do so.

    USDC issuer Circle has been hit with a class action lawsuit from Drift Protocol investors who lost money during the April 1 exploit that saw $285 million drained from the the Solana DeFi platform.

    The suit, filed on April 14, accuses Circle Internet Financial of failing to freeze stolen funds during the exploit.

    The lawsuit centers on an eight-hour window during which attackers moved $232 million in USDC from Solana to Ethereum using Circle’s Cross-Chain Transfer Protocol. The hackers had exploited Drift Protocol through pre-signed administrative transfers using “durable nonces,” a legitimate Solana feature they weaponized weeks before the April 1 attack.

    Drift Protocol subsequently linked North Korean state-affiliated hackers to the attack, noting that they had infiltrated the company over the course of six months by posing as a quantitative trading firm.

    The incident prompted sharp criticism of Circle from within the crypto community, with blockchain investigator ZachXBT accusing the firm of having been “asleep,” during the Drift exploit, adding, “Why should crypto businesses continue to build on Circle when a project with 9 fig TVL could not get support during a major incident?”

    Circle maintains it acted appropriately within legal constraints. “Circle is a regulated company that complies with sanctions, law enforcement orders, and court-mandated requirements,” a company spokesperson said. Earlier this week, CEO Jeremy Allaire warned that unilateral freezing decisions outside established legal processes could create a “significant moral quandary.”

    Chief Strategy Officer Dante Disparte reinforced this position in a blog, stating that, “when Circle freezes USDC, it is not because we have decided, unilaterally or arbitrarily, that someone’s assets should be taken from them. It is because the law requires us to act.”

    While Circle defended its position, Drift Protocol secured recovery commitments of up to $127.5 million from Tether and $20 million from other partners on Thursday. Tether CEO Paolo Ardoino positioned his firm as more responsive, stating that, “Tether’s role in the digital assets ecosystem is to provide a platform for individuals and institutions alike that is ready to step forward to help the industry in the moment of darkness.”

    The legal action arrives amid broader concerns about stablecoin issuers’ responsibilities in combating illicit finance. TRM Labs data shows around $141 billion in stablecoin transactions last year were linked to illicit activity including sanctions evasion and money laundering, while ZachXBT has documented approximately $420 million in suspicious USDC flows since 2022 that went unblocked.

    Circle reported soaring USDC circulation and transaction volume figures in its Q4 2025 report, with Allaire claiming that the firm would grow in tandem with the artificial intelligence industry, and “drive the greatest acceleration of economic activity we’ve ever seen in human history.”

  • Negative Funding Rates Hit Yearly High as Bitcoin Tests $76K

    Negative Funding Rates Hit Yearly High as Bitcoin Tests $76K

    In brief

    • Bitcoin funding rates have remained negative for over a month even as BTC touched $76,000, signaling heavy bearish positioning.
    • A potential uptrend could see Bitcoin revisit $125,000 in 30-60 days, Decrypt was told.
    • Despite bullish catalysts, analysts remain cautious, highlighting $80,000 as a key trigger level; failure risks a double-digit sell-off similar to that seen in May 2022.

    Bitcoin’s recent rally toward $76,000 faces a dilemma, leaving investors split on its near-term outlook.

    Funding rates for Bitcoin—a fee paid by derivatives traders to maintain the alignment between spot and futures prices—have remained negative for over a month and hit the highest level this year, according to Coinglass data.

    Negative funding rates indicate investors are shorting the recent rally with the expectation of a reversal.

    The divergence between bearish derivatives positioning and bullish spot catalysts sets up a potential short squeeze—or a bull trap—depending on which side breaks first.

    “Funding rates this negative tell you the market is heavily short,” Daniel Reis-Faria, CEO of ZeroStack, told Decrypt.

    The derivatives data directly contrasts with Bitcoin’s recent uptick, which was in part driven by bullish catalysts such as sustained ETF inflows, regulatory development surrounding the CLARITY Act, and the two-week ceasefire between the U.S. and Iran, Decrypt previously reported.

    “For a squeeze to gain real momentum, Bitcoin would need to break and hold above $80,000,” Illia Otychenko, lead analyst at crypto exchange CEX.IO, told Decrypt.

    Such a move could trigger “cascading liquidations of short positions and accelerate the rally,” Otychenko said.

    Reis-Faria’s bullish forecast involves Bitcoin pushing close to “$125,000 in the next 30 to 60 days,” adding that a short squeeze would help this case.

    Bitcoin is currently trading at around $75,580, up 1.2% in the past 24 hours after having reached an intraday high of $76,114, according to CoinGecko data.

    Short squeeze or bull trap?

    At this stage, a short squeeze isn’t guaranteed.

    Options data reveal the 7- and 30-day 25-delta skew hovers between -2% to -4%, according to Deribit, suggesting that investors are paying a premium for downside protection via bearish bets.

    Additionally, the 0.72 put/call ratio is climbing, also reflecting growing demand for downside protection. “The pattern closely resembles late May 2022, when a similar squeeze setup instead preceded a double-digit sell-off,” Otychenko said.

    Despite the demand from ETF investors and improving geopolitical outlook, there is a “real risk this setup turns into a bull trap rather than a breakout,” he warned.

    Experts who spoke to Decrypt also maintained a similar outlook, adding that the geopolitical risks haven’t subsided but merely paused. A resumption of the U.S.-Iran war could further push oil prices higher, awakening inflation concerns and subsequently reducing risk appetite, keeping Bitcoin and the broader financial markets capped.

    On prediction market Myriad, owned by Decrypt‘s parent company Dastan, users are increasingly optimistic on Bitcoin’s prospects. They now place a 67% chance on its next move taking it to $84,000 rather than $55,000, up from 54% at the start of the week. Myriad users are similarly positive about the geopolitical situation, putting a 66% chance on the number of ships transiting the Strait of Hormuz averaging more than 15 before May, up from 49% on Monday.

  • Charles Schwab Weighs Prediction Markets Move as Bitcoin, Ethereum Trading Nears

    Charles Schwab Weighs Prediction Markets Move as Bitcoin, Ethereum Trading Nears

    In brief

    • Charles Schwab President and CEO Rick Wurster indicated that America’s largest discount brokerage will likely support prediction markets.
    • However, he said that the company plans to steer clear of topics that touch pop culture, politics, and sports in favor of wagers tied to financial events.
    • Separately, the company said that it is rolling out access to Bitcoin and Ethereum trading in the coming weeks.

    America’s largest discount brokerage is eyeing prediction markets, but Charles Schwab President and CEO Rick Wurster sees a big distinction between speculation on Taylor Swift’s love life and the latest inflation numbers.

    “At some point, we will likely have prediction markets,” Wurster said during the company’s first-quarter earnings call on Thursday, describing wagers on financial events as distinct from topics like sports, politics, and pop culture.

    With $11.8 trillion in total client assets, Charles Schwab’s support of prediction markets would serve as the latest sign that Wall Street giants are embracing technology historically viewed as a fringe playground or regulatory gray area. However, Wurster indicated that Charles Schwab isn’t among firms racing to bring products associated with the sector to market.

    “It’s not at the top of our clients’ list,” he said. “And if you look at the stats on the success of gamblers, they’re not strong and people generally lose money.”

    The assessment comes as exchange operators like Cboe Global Markets prepare to debut event contracts tied to financial events, mirroring platforms like Polymarket and Kalshi while using traditional financial rails. And last month, Nasdaq filed with the SEC to offer options contracts for yes-or-no bets on whether a specified event happens.

    “That’s something certainly we will take a hard look at and then will be quite straightforward for us to offer,” Wurster said. “When we do, we’ll stay away from gambling.”

    Whether it’s Robinhood or Coinbase, prediction markets have emerged as core offerings for platforms aimed at retail investors through integrations with Kalshi. Last week, sports wagers accounted for 78% of the platform’s volume at $2.7 billion, according to a Dune dashboard.

    Asked whether Charles Schwab’s prediction market offering would tap Polymarket or Kalshi, a spokesperson told Decrypt the company—which notched a record 9.9 million trades in the first quarter—doesn’t have anything to share beyond Wurster’s comments at this time.

    As Robinhood and Coinbase have expanded their offerings, so too has Charles Schwab, which said Thursday that it plans to roll out access to trading Bitcoin and Ethereum in the coming weeks. At a rate of 0.75% per trade, the firm said in an announcement that its fees are “among the lowest in the industry.”

    The discount brokerage said it plans to grow its crypto offering over time by adding a suite of features Robinhood and Coinbase users are already familiar with. That includes the ability to deposit and withdraw digital assets, as well as an expansion of the tokens it supports.

  • Stack BTC CEO Steps Down as Farage-Linked Bitcoin Venture Reshuffles Leadership

    Stack BTC CEO Steps Down as Farage-Linked Bitcoin Venture Reshuffles Leadership

    In brief

    • Stack BTC CEO Jai Patel has exited the Bitcoin treasury firm’s board, with David Galan taking over as chief executive.
    • Reform UK leader Nigel Farage has invested around $291,000 in the firm.
    • The Liberal Democrats have called for an FCA inquiry into Farage’s promotion of Stack BTC.

    Stack BTC has replaced its chief executive after completing a shift in strategy, marking a fresh attempt to stabilise the UK Bitcoin-focused investment vehicle and bolster investor confidence. The company said on Wednesday that Jai Patel, who founded the business in its earlier form, had stepped down from the board with immediate effect.

    Announcing the change in a tweet, the firm said that incoming chief executive David Galan brings a mix of dealmaking, financial and operational experience suited to its approach.

    “Stack BTC isn’t a fund. It isn’t a single-thesis bet. It acquires cash-generative operating businesses and uses that engine to accumulate Bitcoin,” it said.

    “Executing that model at scale requires someone who understands the numbers, can close deals, and can manage institutional capital relationships, all at once. David does.”

    The company holds just over 68 BTC, valued at $4.76 million in current market prices. It reported an average entry price of about $70,000 per Bitcoin and said the position is up 2.7%.

    The leadership switch comes as cryptocurrency businesses become increasingly entangled with UK political figures, with Reform UK leader Nigel Farage among the most prominent political advocates of the sector. He announced his backing of the company in early March.

    From Kasei Holdings to Stack BTC

    Stack BTC relaunched in March with investment from Farage and former Conservative chancellor Kwasi Kwarteng, recasting itself as a Bitcoin treasury company. Its strategy centres on buying profitable operating businesses and using their cash flows to build a growing Bitcoin reserve.

    The business originated as Kasei Holdings. It was established in 2021 before changing its name to Kasei Digital Assets and then finally StackBitcointreasury.

    Since rebranding, the company has sought to present itself as a more focused vehicle. Patel remains a shareholder, while Galan—who has a background in property and corporate finance—has been tasked with delivering the revised model.

    Farage invested £215,000 ($291,000) in the relaunched company and also took part in a £260,000 ($352,000) fundraising round earlier this year. The value of his holding has risen alongside movements in the Bitcoin price.

    Some industry figures have expressed doubts about the venture’s positioning. Speaking to The Guardian, Ian Taylor of CryptoUK called the project a “PR branding exercise,” arguing that investors should “be doing their due diligence on the financials, the quality and experience of the management.”

    Earlier this week, the Liberal Democrats called for an FCA inquiry into a promotional video released by Stack featuring Farage. Party leader Daisy Cooper said the regulator “must investigate whether Farage’s plans to cash in on crypto could potentially amount to market abuse and a conflict of interest,” accusing him of “using the Donald Trump playbook to put his own financial interests above the public good.”

    Speaking to the BBC, a spokesperson for Farage stated that the video, which announced Slack’s purchase of £2 million in Bitcoin, was a “photo call,” and that the Reform UK leader “bought the crypto on behalf of Stack and not personally.”

    Reform UK and crypto

    Reform UK has embraced cryptocurrency more openly than other major parties, previously accepting digital asset donations and promoting pro-crypto policies.

    Campaigners and politicians have argued that crypto-based donations could obscure the origin of funds or enable foreign influence in UK elections. The government has responded by introducing a temporary ban on such donations following a review into electoral risks, with further rules expected.

    Farage and his supporters have pushed back, arguing that digital assets can be accommodated within existing frameworks and warning that tighter controls could disadvantage newer political entrants.

    Stack BTC and Nigel Farage have both been approached for comment.

  • Tom Lee’s BitMine Posts $3.8 Billion Quarterly Loss Due to Ethereum Price Plunge

    Tom Lee’s BitMine Posts $3.8 Billion Quarterly Loss Due to Ethereum Price Plunge

    In brief

    • BitMine posted a net loss of more than $3.8 billion during the three-month stretch ending in February.
    • The firm attributes most of the losses to the unrealized or paper losses mounting from its Ethereum holdings.
    • Shares of BMNR are up about 1% on Wednesday, but have slid nearly 60% in the last six months.

    Leading Ethereum treasury firm BitMine Immersion Technologies lost more than $3.8 billion in the quarterly period ending on February 28, according to a new 10-Q the firm filed with the SEC on Tuesday. 

    The firm’s net loss figure of $3.81 billion was largely driven by mounting unrealized losses from its Ethereum holdings, which accounted for nearly 99% of the firm’s reported losses. Over a longer timeframe, the losses are even greater, extending beyond $9 billion in the six-month span ending in February.

    “Our operating model is now anchored by our ETH treasury strategy and capital-light ecosystem services,” the firm wrote, adding that “ETH market conditions, which affect the value of our holdings and the economics of any staking or staking-adjacent activities,” are now a key driver of its results. 

    The firm also posted an unrealized loss of around $21 million for its investment in Eightco (ORBS), a Worldcoin treasury firm that also provides investors exposure to private artificial intelligence giant and ChatGPT maker, OpenAI. (Disclosure: BitMine Chairman Tom Lee is an investor in DastanDecrypt‘s parent company.)

    All in, the results have soured substantially from the same period last year, when the firm reported a loss of just $1.15 million. 

    The biggest culprit? Ethereum.

    The second-largest crypto asset, and the primary treasury vehicle for BitMine, has fallen nearly 53% from its August all-time high of $4,946, recently changing hands at $2,346. ETH was trading around $1,965 at the close on February 28, down from about $2,800 at the start of December.

    BitMine, which relentlessly adds to its holdings—including a $157 million ETH purchase reported earlier this week—now holds 4,874,858 ETH worth more than $11.3 billion. But that’s far less than it has paid to accumulate it, having purchased its first 4.47 million ETH for nearly $17 billion, according to its 10-Q.

    In other words, 92% of the firm’s total ETH holdings were accumulated with an average price of around $3,794 per ETH, or around 63% higher than the asset currently trades. The staggering losses have shrunk in recent days, as ETH has jumped around 4% in the last week of trading. 

    Shares in the firm (BMNR), which were uplisted last week to the NYSE from the smaller NYSE American exchange, are up around 1% on Wednesday, recently changing hands at $21.69. 

    They’ve fallen nearly 60% in the last six months of trading and are down 20% year-to-date.

  • Anthropic Preps Opus 4.7 and Full-Stack AI Studio—While Sitting on Something Much Scarier

    Anthropic Preps Opus 4.7 and Full-Stack AI Studio—While Sitting on Something Much Scarier

    In brief

    • Anthropic is preparing Claude Opus 4.7 and an AI design tool for websites and presentations
    • Claude Mythos remains Anthropic’s true frontier model, and the company won’t release it publicly.
    • The industry still can’t reliably measure AI improvements, making claims about Opus 4.7’s gains hard to verify.

    Anthropic is gearing up to release Claude Opus 4.7 alongside a new AI-powered design tool that lets users build websites, presentations, and landing pages with plain English prompts—news that caused a dip in Adobe, Wix, and Figma shares on Monday, according to The Information.

    The products could drop as soon as this week, a person with knowledge of the plans told The Information. The design tool targets developers and non-technical users alike, putting it on a collision course with startups like Gamma and Google’s Stitch.

    Anthropic did not respond to Decrypt’s request for comment.

    Opus 4.7 isn’t even Anthropic’s most powerful model. That title belongs to Claude Mythos—a cybersecurity-focused beast the company is quietly handing to select security firms while keeping it away from the public.

    The UK’s AI Security Institute recently evaluated Mythos Preview and found it can autonomously execute sophisticated cyber attacks at rates no other model has matched. It became the first AI to complete “The Last Ones,” a 32-step corporate network attack simulation that typically takes human red teams 20 hours. Mythos nailed it in three out of ten attempts, averaging 22 of 32 steps—compared to Opus 4.6’s 16.

    This matters beyond enterprise security. Measuring what AI can actually do has become an industry-wide headache. OpenAI recently called the leading coding benchmark “contaminated,” yet models continue to be compared using those same tests. A separate ARC-AGI-3 evaluation saw Gemini score 0.37% and GPT-5.4 hit 0.26%—while humans got 100%. The result is a landscape where benchmarks are both contested and still used as evidence, making it difficult to contextualize claims about Opus 4.7’s gains until Anthropic releases a detailed model card.

    The relationship between Opus and Mythos is closer than most realize. Anthropic builds its frontier models by fine-tuning atop the Opus line—the same backbone powering public Claude products gets stress-tested and hardened into Mythos. Opus 4.7 is the foundation that eventually gets the cybersecurity kung fu beaten into it.

    Also, Anthropic’s efforts have been steering more towards the development/enterprise use case. The leak of Claude code, the release of the skills system and MCP protocol, the focus on agentic AI and the care on coding benchmarks make this even more apparent. While Anthropic hasn’t formally announced it, the leaks reinforce the broader shift from LLM provider to something that resembles a full-stack “AI studio” model, where Claude doesn’t just generate text but builds and deploys complete products.

    Ethereum DeFi Exchange CoW Swap Pauses Protocol Following Website Compromise

    In brief

    • CoW Swap, an Ethereum-based decentralized exchange aggregator, warned users to avoid interacting with its protocol after suffering a front-end compromise.
    • Although the scope of losses was initially unclear, one noted cybersecurity researcher estimated that $500,000 had been taken from unsuspecting users so far.
    • CoW Swap said the attack didn’t affect the protocol’s underlying smart contracts, but the decentralized exchange aggregator had been paused as a precaution.

    CoW Swap, an Ethereum-based decentralized exchange aggregator, warned users on Tuesday to avoid using the protocol, disclosing that its front-end interface had been compromised.

    “We are now actively working to resolve the situation,” the project frequently used by Ethereum co-founder Vitalik Buterin said in a post to X. “The CoW Protocol backend and APIs were not impacted, but we have paused them temporarily as a precaution.”

    CoW Swap indicated that attackers had gained control of the website domain that users typically visit before engaging with the protocol. That gave bad actors the opportunity to direct users to a different website where funds could be stolen through the approval of malicious transfers.

    Although the compromise didn’t affect CoW Swap’s underlying smart contracts, the protocol appeared to remain frozen three hours after the attack was divulged. Meanwhile, users on Discord reported losses within the project’s official server.

    “I don’t know what to do anymore,” said one user who claimed that they lost more than $50,000 via CoW Swap’s compromised front end. “I have no money at all.”

    Despite apparent frustrations, the scope of losses sustained wasn’t immediately clear. 

    A pseudonymous member of the CoW Swap team who goes by MooKeeper told Decrypt that reports are actively being investigated and verified. They added that a more complete assessment would be released tomorrow or later this week.

    “We have evidence that a small number of users signed malicious approvals for very small amounts,” MooKeeper added.

    Still, a noted cybersecurity researcher who goes by Vladimir S. on X said that around $500,000 worth of digital assets had been “drained from a few addresses so far.”

    Martin Köppelmann, co-founder and CEO of decentralized infrastructure provider Gnosis, noted in a post to X that the attack’s scope appears limited. He said that users are potentially affected only if they approved interactions with CoW Swap within the past few hours.

    Websites that try to trick users by mimicking established DeFi projects aren’t entirely uncommon. Last year, for example, Curve Finance suffered its second DNS hijack. The first one, which took place in 2022, resulted in $570,000 in losses for users.

    Buterin, who has swapped notable amounts of Ethereum for stablecoins using CoW Swap this year, had engaged with the protocol as recently as a week ago, data from on-chain analytics firm Arkham Intelligence showed. In 2024, he also used the decentralized exchange aggregator to offload holdings of a meme coin modeled on a baby pygmy hippo from Thailand.
