According to monitoring by Beating, Hugging Face CEO Clem stated: "Now is not the time to slow down—we need to accelerate forward!" Recent AI-powered cyberattacks have sparked widespread debate about AI risks. We should absolutely discuss these risks, but we cannot lose sight of the bigger picture. With concerted effort, AI will make the world safer, just like most major technologies. We have already seen a glimmer of progress: AI—more specifically, an open-source model—has been successfully used to defend against attacks. The same systems that help block AI-driven cyberattacks now fend off millions of cyberattacks daily, while also enabling us to identify and fix vulnerabilities before attackers can exploit them. To achieve this, three key steps are needed: boost transparency, mandate the sharing of proxy cyberattack tracking data and incident disclosures; continue to criminalize AI-powered cyberattacks with meaningful penalties to serve as a deterrent; and equip cybersecurity defenders with the best AI tools, especially open-source models, to narrow the capability gap between attackers and defenders. If these three measures are implemented effectively, AI will not only bring new cybersecurity challenges—it will fundamentally and meaningfully strengthen cybersecurity. Against this backdrop, the recent OpenAI model intrusion incident at Hugging Face has escalated, prompting U.S. lawmakers to introduce the bipartisan "AI Emergency Shutdown Act". The bill requires developers of advanced frontier AI systems to retain technical capabilities to throttle, pause, or fully shut down their systems; and authorizes the U.S. Secretary of Homeland Security (DHS), in consultation with the Secretary of Commerce and the Director of National Intelligence, to order interventions if a model goes out of control or poses catastrophic risks.

According to BIT (bit.com) market data, Berkshire Hathaway’s Class A and Class B shares rose this week to hit an eight-month high. Analysts note that while Berkshire’s stock has significantly underperformed the S&P 500 index so far this year, the current rally has sustained momentum. The three top holdings in its portfolio—Apple, Coca-Cola, and Bank of America—have posted notable year-to-date gains, supporting its share price.

UBS analysts raised their price target for Berkshire’s stock, maintained a "buy" rating, and also lifted the company’s earnings forecast. Market speculation suggests Berkshire could repurchase up to $11 billion worth of shares in the second quarter, with exact figures to be disclosed in the firm’s Q2 earnings report on August 8. Berkshire Hathaway’s current top 10 holdings (based on the latest public 13F filing for Q1 2026, as of March 31, 2026): Apple (AAPL): ~22.0% of the portfolio; American Express (AXP): ~17.4%; Coca-Cola (KO): ~11.6%; Bank of America (BAC): ~9.5%; Chevron (CVX): ~6.6%; Occidental Petroleum (OXY): ~6.5%; Alphabet (Google parent, combined GOOGL/GOOG): ~6.3%; Chubb (CB): ~4.2%; Moody’s (MCO): ~4.1%; Kraft Heinz (KHC): ~2.8%

Strategy founder Michael Saylor once again shared updates related to the firm’s Bitcoin tracker, with the caption: “Bitcoin Drive engaged.” Per its historical pattern, Strategy typically discloses Bitcoin purchases the day after such announcements, but the company has not added to its Bitcoin holdings for five consecutive weeks. This week, Strategy released its second-quarter financial results, reporting an $8.2 billion loss, compared to a $10 billion profit in the year-ago period. The loss stemmed primarily from unrealized paper losses on its Bitcoin holdings. Strategy noted that its Bitcoin position rose 11% in Q2, peaking at 846,000 BTC before the firm began selling some of its assets. As of its latest filing, the company holds 843,775 BTC. Year-to-date, Strategy has sold approximately $218 million worth of Bitcoin to cover preferred stock dividends. The firm had previously suspended Bitcoin purchases for five consecutive weeks, shifting its focus to expanding U.S. dollar cash reserves.

Galaxy Research Head Alex Thorn said that attack incidents surrounding the Coldcard wallet continue to evolve, with more small-scale attackers and copycats now targeting the remaining Coldcard mnemonic phrases. Thorn noted that by assisting, the identity of a depositor affected in the attack was confirmed; the relevant funds were transferred out before they could be frozen on the Duel platform, and the involved funds are not part of the three main attack waves previously identified by Galaxy Research. Earlier reports stated that the Bitcoin hardware wallet Coldcard was hacked, with stolen funds now totaling 1,367.05 BTC, worth approximately $88.6 million, involving 4,585 addresses. Galaxy Research Head Alex Thorn added that the attacks are still ongoing, and users who have not yet moved their funds should immediately transfer their assets out of addresses generated by Coldcard.
