Core Lightning Confirms AI-Generated Bitcoin Vulnerability
digitaltoday.co.kr reports that Core Lightning has confirmed a vulnerability cited in an AI-generated security report is real. The software advised node operators to quickly apply a patch once it is distributed and verified. Cryptopolitan reported on August 27 that technical details will remain undisclosed for at least two weeks.
Core Lightning stated there is no need to fully shut down a node, recommending the '--offline' flag instead. This flag blocks peer connections while allowing the node to continue monitoring the blockchain for force-close attempts. The notice corrects earlier guidance from Bitcoin developer Calle, who suggested immediate shutdowns on August 26.
Core Lightning restated that upgrading is the priority, with '--offline' serving as an alternative when an upgrade is not possible. A small team reviewed AI-generated reports from multiple sources over ten days, with work continuing for weeks. Specific details of the vulnerability remain confidential to allow developers time to release fixes. Operators should verify signatures after patches are released to ensure security.
How the market reacted
Whalio's own Binance spot order flow for BTC, measured when this story was written up on 28 August 2026. Not the outlet's figures.
BTC is trading at $80,249.58 with a 1-hour buy ratio of 50.7%, indicating short-term buying interest. However, the 4-hour buy ratio drops to 39.8%, suggesting that buying pressure is fading over a slightly longer timeframe. The 24-hour buy ratio stands at 45.2%, showing a balanced but slightly bearish sentiment over the full day. Volume Delta for the 1-hour period is positive at $591,721, reflecting immediate buying activity. In contrast, the 4-hour Volume Delta is negative at -$36,806,801, and the 24-hour delta is -$123,102,218, indicating net selling pressure over longer periods. This divergence suggests that while short-term buyers are active, larger flows are pushing the price down.
The latest daily buy ratio of 46.7% sits at the 18th percentile of the last 322 days, against a median of 49.2% - weaker buying than most days.
