Kairos DDoS botnet spreads to Linux devices via passwordless Telnet root logins

Nozomi Networks reports a previously undocumented Go-based DDoS bot, Kairos, spreading via exposed Telnet services that accept root with an empty password. The bot opens large numbers of real TCP connections to victims and holds them open, and it has no persistence or self-spreading, but it is simple to deploy at scale on exposed devices.
