How they attack

Entry

Lure spreadsheets

Like sending a file titled something irresistible, such as a list of political prisoners, that springs a trap when opened.

Inside

Picking victims before the payload

Like a courier who checks who opens the door before deciding whether to hand over the real package.

Goal

Swaying opinion with fake stories

Like pinning a convincing fake article on a hijacked news site's notice board.

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.
