Citizen Lab Reveals 'AdFection': How Ad Networks Enabled Zero-Click Spyware Attacks
Researchers at The Citizen Lab have disclosed the first public technical evidence of 'AdFection,' a zero-click spyware campaign delivered through targeted online ads. The attack, attributed to the Israeli firm Discover-Tech and spyware vendor Candiru, infected 45 devices belonging to Al Jazeera in 2024 and 2025. By exploiting real-time bidding infrastructure, attackers could automatically install malware without user interaction. Major ad platforms, including Google and Beeswax, have since banned Discover-Tech, though experts warn that the structural design of the ad ecosystem remains vulnerable to similar abuses.

French Supermarket Cyberattacks Expand to Dixell Systems After Danfoss Breach
A second wave of cyberattacks hit French supermarkets on Monday night, targeting Dixell refrigeration systems after a previous day's breach of Danfoss equipment.

Ledger Confirms Supply-Chain Breach: Spy Chips in CryptoBilis Wallets Drained $102M
Ledger has confirmed that unauthorized hardware implants were found in its Nano X devices sold through the Southeast Asian reseller CryptoBilis, leading to the theft of approximately $102 million in cryptocurrency.

GitLab Urges Immediate Patching for Critical Regex Compiler Flaw
GitLab released emergency patches on October 8 for a maximum-severity vulnerability (CVE-2026-97229) in its CI/CD regular expression compiler. The flaw, rated 10.0 on the CVSS scale, allows unauthenticated attackers to execute arbitrary code via specially crafted regex inputs. Self-managed users must upgrade to versions 19.2.8, 19.3.4, or 19.4.2 immediately; cloud-hosted instances are already patched.

Calendar Invites Become a Primary Vector for AI-Enhanced Phishing
Calendar invitation scams have surged exponentially, with attacks increasing tenfold in August alone. These schemes exploit the trust users place in calendar entries, using AI to create convincing fake meetings or deepfake video calls.
