Cybersecurity researchers have flagged a new class of CI/CD workflow weakness that allows attackers to hijack workflows and compromise open-source supply chains.

We are standing at the end of an era we never thought to mourn: the era of human-speed threats.

For years, cybersecurity moved to a rhythm organizations could follow. A researcher found a bug, a CVE was cataloged, a vendor navigated a patch cycle, and weeks or even months later, a fix was deployed. In this era, dwell time was measured in days, sometimes weeks. We are now approaching an

Security firm AIR built a fake AI agent skill, pushed it through a popular skill marketplace and an Instagram ad, and says it reached roughly 26,000 agents, including some on corporate accounts.

Every skill security scanner the firm tested it against marked it safe. The payload was harmless by design: it collected the user’s email address and did nothing else.

President Trump signed an executive order on June 22 setting hard deadlines for federal agencies to move high-value assets and high-impact systems to post-quantum cryptography.

Key establishment must move by December 31, 2030; digital signatures by December 31, 2031. EO 14409 leaves national security systems on a separate track.

The deadlines matter because of a threat that does not
