Malwarebytes reviews security incidents from the week

Malwarebytes Labs’ week-in-security briefing for 2–8 November 2026 collates a range of incidents and issues from across the threat landscape, as reported by Malwarebytes’ own research and reporting.

The roundup highlights that major platforms have become subjects of legal action in California, with Big Tech – including Google, Meta and TikTok – challenging the state’s plan to regulate kids’ scrolling, while other posts cover a US warning about remote access vulnerabilities affecting supermarket refrigeration and cold-chain monitoring systems.

Additional items in the week include a case where a NIKKEI PC launcher compromise exposed players’ passwords and personal files, alongside coverage of scams and frauds such as phone return scams that exploit real deliveries to create billing losses for victims.

Other notable entries in the series point to a mix of tech, threat intel and consumer-bocused security news. For example, there are discussions around affiliate and review manipulation in underground markets, as well as breaches and data exposure issues, including an incident involving Revolve that potentially affected up to 1.5 million people.

The material also references associated warnings, research notes and incident narratives from across Malwarebytes’ publications in that period, offering a snapshot of ongoing concerns—from exploitation and credential exposure to social engineering and privacy-related challenges.
