Exploited vulnerabilities and targeted products

Microsoft

If you run any of these products, first make sure they are updated to a fixed version.

How they attack

Entry

Abusing website input flaws

Like writing a trick phrase on the front-desk form that makes the clerk open the back door.

Inside

Grabbing administrator rights

Like swapping a part-timer's badge for the store manager's badge.

Goal

Rigging search rankings

Like changing the shop sign only when the search-engine inspector visits, so it recommends another shop.

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.
