NPM のパッケージ ua-parser-js にマルウェアが混入
The npm package ua-parser-js had three versions published with malicious code. Users of affected versions (0.7.29, 0.8.0, 1.0.0) should upgrade as soon as possible and check their systems for suspicious activity. See this issue for details as they unfold.
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer.

The average ransom payment amount remained relatively constant in Q3, while the median increased by over 50%. We attribute this shift to less large outlier ransom payments from a small subset of large companies, versus a higher proportion of payments coming from mid-market sized victims. Ever since the pipeline attacks this spring, we have seen statistical evidence and intelligence showing that ransomware actors are trying to avoid larger targets that may evoke a national political or law enforcement response. This shift from ‘Big Game Hunting’ to ‘Mid Game Hunting’ is personified in both the ransom amount statistics but also the victim size demographics from the quarter.
