ASUS Router Apocalypse: 50,000 Devices Hacked in Alleged China-Linked Operation WrtHug
Operation WrtHug has compromised around 50,000 ASUS routers, targeting end-of-life models primarily in Taiwan and Southeast Asia. Researchers suspect a China-linked cyber espionage campaign exploiting multiple vulnerabilities. The attack shares a playbook with previous Chinese cyber campaigns, leaving users with one clear mantra: patch, patch, patch those routers!

Hot Take:
Looks like ASUS routers are playing a risky game of “Who Can Get Hacked the Most?” with vulnerabilities older than yesterday’s leftovers. Is it a bird? A plane? Nope, just another cyber espionage campaign possibly from China, exploiting routers that should probably be in a museum by now.
Key Points:
- Around 50,000 ASUS routers hacked in “Operation WrtHug”, possibly linked to China.
- Exploits target end-of-life ASUS WRT routers with vulnerabilities from 2023.
- Most compromises are in Taiwan and Southeast Asia, but not mainland China.
- Identical exploits as the previous AyySSHush campaign, yet few overlaps in compromised devices.
- Unusual self-signed TLS certificate with a 100-year expiration date is a key infection indicator.
