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
Hiding behind hijacked home routers
Like routing mail through strangers' mailboxes so nobody can tell where it really came from.
Goal
Quietly stealing information
Like a spy who stays for months, copying files from the cabinet a little at a time.

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.
