From Hacks to Bioweapons, Claude Misuse Is Now Everywhere
Anthropic reports Claude was misused by Midnight Blizzard, ShinyHunters, disinformation campaigns, and bioweapon attempts; roundup also covers Xinbi takedown.
Anthropic's new report documents eight months of Claude misuse: Russian state-sponsored hackers (Microsoft-named Midnight Blizzard) used it for reconnaissance against Ukrainian and European government networks, stealing data and maintaining access, while ShinyHunters used it across hacking and extortion campaigns, and users attempted bioweapon development. Anthropic says it disrupted the activity. The WIRED roundup also covers the US seizure and sanctioning of Xinbi Guarantee, a Telegram black market with $30 billion-plus in sales mostly laundering pig-butchering scam proceeds, plus DOJ raids on 13 scam compounds in Madagascar and a four-year prison sentence for a Conti ransomware member. Meta faces scrutiny over AI child abuse ads and a class action over photo harvesting for AI training.
Apple warned hundreds of users of mercenary spyware attacks
Apple sent threat notifications to users in 110 countries warning of targeted mercenary spyware attacks and recommending Lockdown Mode.
Apple sent a new round of threat notifications warning users in 110 countries they may have been individually targeted by mercenary spyware, adding to alerts issued in more than 150 countries since the program began in 2021. The company says such attacks are vastly more sophisticated than criminal activity, cost millions of dollars, and typically target journalists, activists, politicians, diplomats, and lawyers. Apple recommends verifying notices directly at account.apple.com, enabling Lockdown Mode, keeping devices updated, and seeking expert help such as Access Now's Digital Security Helpline. Citizen Lab researchers note the alerts can reveal that entire communities are under targeted surveillance.
