Threat actors have been exploiting a couple of vulnerabilities affecting some DrayTek enterprise routers in attacks that started before patches were released by the vendor.
In early December 2019, researchers at the Network Security Research Lab of Chinese cybersecurity firm Qihoo 360 noticed that some DrayTek Vigor routers had been targeted in attacks exploiting a vulnerability which at the time had a zero-day status.
Researchers then noticed on January 28 that a second zero-day flaw affecting DrayTek Vigor routers had been exploited in attacks by a different threat group.
Qihoo 360 unsuccessfully attempted to notify DrayTek of the attacks exploiting the first vulnerability in early December.
This is not the first time malicious actors have targeted DrayTek routers using zero-day vulnerabilities.
