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
A harmless-looking first invitation
Like a con artist who first sends a polite invitation and only works on the people who write back.
Entry
A sign-in page that looks real
Like setting up a fake reception desk in front of the real one and quietly copying every visitor's pass.
Goal
Gathering policy intelligence
Like peeking into an expert's briefcase to learn a government's plans before they are announced.

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.
