CVE-2023-42793

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.

Entry

Getting in through a supplier

Like stealing the spare key from the cleaning company instead of breaking into headquarters.

Entry

Emails pretending to be someone you know

Like a letter from a 'colleague' with an envelope that springs a trap when opened.

Goal

Quietly stealing information

Like a spy who stays for months, copying files from the cabinet a little at a time.

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.
