Two vulnerabilities affecting over one million routers, and disclosed earlier this week, are now under attack by botnet herders, who are trying to gather the vulnerable devices under their control.
Attacks started yesterday, Thursday, May 3, according to Netlab, the network security division of Chinese cyber-security vendor Qihoo 360.
It did not take long for miscreant to spot and add this to their weapon library, we have captured activity utilizing CVE-2018-10561 CVE-2018-10562 with an active C2 up and running in VN. We will share more details soon. https://t.co/I7lE3gRWr5

Exploitation of these two flaws started after on Monday, April 30, an anonymous researcher published details of the two vulnerabilities via the VPNMentor blog.
Simple hacks expose Dasan GPON routers

By combining these two issues, the anonymous researcher said he was able to bypass authentication and execute code on vulnerable devices. A video by the VPNMentor crew summarizes the findings.
