Ransomware saw a resurgence in 2023, Mandiant reports

Mandiant's report documents a surge in ransomware activity in 2023 — 50 new variants (about a third derived from existing families), a 75% year-over-year increase in data-leak site posts, and roughly $1 billion in victim ransom payments — with significant operational impacts on healthcare (notably an Ascension outage tied to Black Basta) and ALPHV and LOCKBIT accounting for the largest shares of activity.
