In the latest illustration of how quickly attackers can exploit newly disclosed flaws, Russia’s notorious APT28 cyber-espionage group has begun abusing a recently patched Microsoft vulnerability to steal emails and deploy malicious payloads against organizations in Central and Eastern Europe.

CVE-2026-21509 is a security feature bypass vulnerability in Microsoft Office for which Microsoft rushed an out-of-cycle patch on Jan. 26 after confirming active zero-day exploitation. The US Cybersecurity and Infrastructure Security Agency (CISA) added the flaw to its database of known exploited vulnerabilities at the time.

Mozilla on Monday announced a new controls section in its Firefox desktop browser settings that allows users to completely turn off generative artificial intelligence (GenAI) features.

”It provides a single place to block current and future generative AI features in Firefox,” Ajit Varma, head of Firefox, said. ”You can also review and manage individual AI features if you choose to use them. This lets you use Firefox without AI while we continue to build AI features for those who want them.”

Mozilla first announced its plans to integrate AI into Firefox in November 2025, stating it’s fully opt-in and that it’s incorporating the technology while placing users in the driver’s seat.

The AI boom could cost Apple up to $57 more per iPhone – for memory chips alone.

”The rate of increase in the price of memory is unprecedented,” says Mike Howard, an analyst at TechInsights, speaking to the Wall Street Journal. By the end of this year, the price of DRAM will quadruple from 2023 levels, and NAND will more than triple.

For Apple, the numbers are stark: The base-model iPhone 18 due this fall could cost $57 more in memory alone compared with the current iPhone 17 – a significant hit to profit margins on a device that retails for $799. This aligns with recent rumors that Apple may delay the base model’s release to later this year.

The Department of Justice left multiple unredacted photos of fully nude women or girls exposed as part of Friday’s dump of more than 3.5 million pages of files related to the investigations and prosecutions of Jeffrey Epstein and Ghislaine Maxwell.

In some of the photos, the women or girls were either fully nude or partially undressed, posed for cameras, and exposed their genitals.
