Anthropic on Wednesday revealed that it disrupted a sophisticated operation that weaponized its artificial intelligence (AI)-powered chatbot Claude to conduct large-scale theft and extortion of personal data in July 2025. "The actor targeted at least 17 distinct organizations, including in healthcare, the emergency services, and government, and religious institutions," the company said . "Rather than encrypt the stolen information with traditional ransomware, the actor threatened to expose the data publicly in order to attempt to extort victims into paying ransoms that sometimes exceeded $500,000." "The actor employed Claude Code on Kali Linux as a comprehensive attack platform, embedding operational instructions in a CLAUDE.md file that provided persistent context for every interaction." The unknown threat actor is said to have used AI to an "unprecedented degree," using Claude Code, Anthropic's agentic coding tool, to automate variou...

A new large-scale campaign has been observed exploiting over 100 compromised WordPress sites to direct site visitors to fake CAPTCHA verification pages that employ the ClickFix social engineering tactic to deliver information stealers, ransomware, and cryptocurrency miners. The large-scale cybercrime campaign, first detected in August 2025, has been codenamed ShadowCaptcha by the Israel National Digital Agency. "The campaign [...] blends social engineering, living-off-the-land binaries (LOLBins), and multi-stage payload delivery to gain and maintain a foothold in targeted systems," researchers Shimi Cohen, Adi Pick, Idan Beit Yosef, Hila David, and Yaniv Goldman said . "The ultimate objectives of ShadowCaptcha are collecting sensitive information through credential harvesting and browser data exfiltration, deploying cryptocurrency miners to generate illicit profits, and even causing ransomware outbreaks." The attacks begin with unsuspecting users visiting a c...

Cybersecurity researchers have discovered a new variant of an Android banking trojan called HOOK that features ransomware-style overlay screens to display extortion messages. "A prominent characteristic of the latest variant is its capacity to deploy a full-screen ransomware overlay, which aims to coerce the victim into remitting a ransom payment," Zimperium zLabs researcher Vishnu Pratapagiri said . "This overlay presents an alarming '*WARNING*' message, alongside a wallet address and amount, both of which are dynamically retrieved from the command-and-control server." The mobile security company said the overlay is remotely initiated when the command "ransome" is issued by the C2 server. The overlay can be dismissed by the attacker by sending the "delete_ransome" command. HOOK is assessed to be an offshoot of the ERMAC banking trojan, which, coincidentally, had its source code leaked on a publicly accessible directory over the int...

Cybersecurity today moves at the pace of global politics. A single breach can ripple across supply chains, turn a software flaw into leverage, or shift who holds the upper hand.
