Researchers saw several IoT botnets using one of the bugs in the wild after a proof-of-concept was published in March. The Mootbot botnet has been using a pair of zero-day exploits to compromise multiple types of fiber routers. Other botnets have attempted to do the same, but have so far failed, according to researchers. For it to be used successfully to compromise a target router, it must be paired with a second vulnerability, researchers said. The researchers recommended that to protect against the threat, users that have fiber-based internet access routers should check and update their device firmware.
