In February, hardware maker Zyxel fixed a zero-day vulnerability in its routers and VPN firewall products after KrebsOnSecurity told the company the flaw was being abused by attackers to break into devices.
Security experts at Palo Alto Networks said Thursday their sensors detected the new Mirai variant - dubbed Mukashi - on Mar. 12.
The new Mirai strain targets CVE-2020-9054, a critical flaw that exists in many VPN firewalls and network attached storage devices made by Taiwanese vendor Zyxel Communication Corp., which boasts some 100 million devices deployed worldwide.
Like other Mirai variants, Mukashi constantly scans the Internet for vulnerable IoT devices like security cameras and digital video recorders, looking for a range of machines protected only by factory-default credentials or commonly-picked passwords.
Zyxel issued a patch for the flaw on Feb. 24, but the update did not fix the problem on many older Zyxel devices which are no longer being supported by the company.
