Attributions are quoted as assessed by governments and security vendors. VulnPulse does not make attributions itself.
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.
