An Iranian-linked hacker group leaked sensitive personal data belonging to former Israeli prime minister Naftali Bennett. It is one of a number of attacks linked to Tehran that have raised concerns about Israel’s cyber defenses. The Handala hacking group said it breached a phone used by Bennett and published hundreds of his chat messages. 

  • The group also put out a 141-page contact list that included several world leaders.
  • Bennett said his Telegram account had been hacked and contents from his contact list, photos and chats “both authentic and forged” were released. He denied that his phone itself had been hacked. (WSJ)

Corporate cybersecurity teams are early and aggressive adopters of AI, according to a study from the Cloud Security Alliance, a nonprofit cyber education group. Of 300 tech and security professionals surveyed globally, 48% said they have tested AI for cyber functions and another 44% said they plan to in the next year. Agentic AI, in particular, is of interest with 19% of respondents saying they already use the tech and 47% plan to adopt the tools in the coming year. 

  • Organizations use an average of 2.6 AI platforms, with the three most popular from OpenAI, Google and Anthropic, in that order, the survey found.

New operational technology bugs: The Cybersecurity and Infrastructure Security Agency released advisories about nine vulnerabilities in industrial control systems. They include problems in products from Mitsubishi Electric, National Instruments, Rockwell Automation, Schneider Electric, Siemens and other companies. 

  • Related: Edge devices are prime targets of hackers looking to break into OT systems, according to new research from Forescout Technologies. In an analysis of attacks on a honeypot set up for study, 67% of attempts were made on industrial routers and firewalls and 33% against OT devices, Forescout said. (IT Security Guru)
