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
Booby-trapped documents
Like an ordinary-looking envelope that starts copying your keys as soon as you open it.
Inside
Remote control with off-the-shelf tools
Like using hardware-store tools instead of custom ones, so the job is harder to trace.

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.
