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
Exploiting internet-facing devices
Like finding a broken lock on the company's front gate (VPN or firewall) and walking in.
Goal
Quietly stealing information
Like a spy who stays for months, copying files from the cabinet a little at a time.
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.
