How they attack
Entry
Exploiting internet-facing devices
Like finding a broken lock on the company's front gate (VPN or firewall) and walking in.
Inside
Blending in with built-in tools
Like a burglar who brings no tools and uses only what is already in the house, so nothing looks out of place.
Goal
Double extortion: encrypt and leak
Like locking your safe and also taking copies of the papers inside, threatening to publish them unless you pay.

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.
