Two things landed within days of each other this week. A security startup reported 21 previously unknown vulnerabilities in FFmpeg, the media library inside almost everything that touches video, all of them found by an autonomous AI agent.
The same week, Google shipped Chrome 149 with patches for 429 security bugs, the most ever in a single release.
Only the FFmpeg bugs were found by AI. Swati Khandelwalhttp://www.blogger.com/profile/ [email protected]

Tech giant Toshiba and mega-retailer Muji warned visitors that suspicious sign-in screens popping up on their websites could collect credentials. [...]
Operating system makers take many steps to prevent their wares from accepting commands from remote devices. The safeguards, designed to thwart malicious attacks, typically require hackers to jump through all kinds of hoops to bypass the measures. But what if remote code execution were as simple as being within Bluetooth range of a speaker connected to the targeted device?
It turns out it can, at least when the speaker is a Sound Blaster Katana V2X sold by Singapore-based Creative Technologies. The speaker, which sells for $283, is widely acclaimed with numerous reviews showering praise on the sound and performance of it and its predecessor, the Sound Blaster V2.
A PC-pwning proxy
Researcher Rasmus Moorats stumbled on the hack by accident, after he purchased a Katana V2X, a soundbar that connects to PCs, Macs, and Linux devices over USB or Bluetooth. Moorats was curious if he could create a Linux tool that communicated with his speaker. He discovered he could do so through CTP, a proprietary mechanism he guesses is short for Creative Transport Protocol. Read full article

Technology companies announced 38,242 job cuts in the US in May 2026, the highest monthly total for the sector since August 2024, according to research by employment placement company Challenger, Gray & Christmas. So far this year the company has observed 123,653 US technology job cuts, a rise of 66 percent from the same period in 2025.
These figures represent the third successive month that there has been an increase in job layoffs across all sectors, the company said.
“The labor market is being reshaped by technology in real time. AI is now the leading reason companies give for cutting jobs and the primary industry citing it is technology,” said Andy Challenger, chief revenue office at Challenger, Gray and Christmas.”
AI was blamed for 38,579 of the 97,006 job cuts announced across all industries tracked by the company. It accounted for 40% of the cuts observed in May, up from 7% in January.
This year has already seen some major layoffs in technology. In March, HPE slashed 2,500 jobs from its wage bill, while Oracle announced plans to shed an unspecified number of developers. And the cuts keep on coming, just last month, Meta shed 8,000 employees.
