ChainDrop supply chain compromise: Anatomy of a self-propagating worm
A self-propagating worm embedded in over 400 malicious npm packages spread through software supply chains by automatically republishing infected updates, stealing credentials along the way. Microsoft's security team has published a detailed breakdown of how the attack worked and how to detect or remediate it.
Why this matters: Most developers do not inspect every package they pull in. That is the whole point of this attack. A worm that spreads by republishing itself inside a trusted ecosystem does not need to trick you once — it keeps moving on its own. Four hundred compromised packages is not a small incident. Any project that pulled in an affected dependency may have handed over credentials without knowing it. If your team uses npm, now is the time to check, not later.
