Exploited vulnerabilities and targeted products
If you run any of these products, first make sure they are updated to a fixed version.
How they attack
Entry
Coming in through the VPN
Like using a stolen badge at a side door that was never repaired (an unpatched SonicWall VPN).
Inside
Moving very fast
Like a burglar who skips the scouting and locks every room the same day they get in.
Goal
Locking files for ransom
Like locking every filing cabinet in the office and charging for the keys.

Leak counts only add up figures disclosed by the affected companies or authorities, never the attackers' own claims. We do not list victim names or link to leak sites.
The alert level is calculated automatically from reports and advisories in the last 90 days, known exploited vulnerabilities, and whether the group has targeted Japan.
