Bitdefender researchers have uncovered an emerging botnet that uses advanced communication techniques to exploit victims and build its infrastructure. The bot, dubbed HNS, was intercepted by our IoT honeypot system following a credentials dictionary attack on the Telnet service.
The bot was first spotted on Jan. 10 then faded away in the following days, only to re-emerge on Jan. 20 in a significantly improved form.
Update 26/01/2018 – 14.06 GMT+3
The botnet now controls 32,312 IoT devices. Also, the botnet seems to undergo massive development as new samples compiled for a variety of architectures have been added as payloads:
