The release of the??was believed to have triggered the ?of activity associated with the?Mirai?botnet. Scans used the PoC on November 22 after the publication of the exploit code on October 31. The PoC triggers in?old ZyXEL PK5001Z routers, which was made public early this year.

Attackers?have discovered a large amount of ZyXEL devices using admin/CenturyL1nk and admin/QwestM0dem as default Telnet credentials. These ZyXEL devices are a combination of a DSL modem and router supplied by US-based internet service providers (ISPs) CenturyLink and Qwest. ZyXEL PK5001Z routers possess a?hardcoded?superuser password?(zyad5001) that could be used to elevate a user¡¯s access to root level and install the DDoS malware.
