The FritzFrog botnet that's been active for more than two years has resurfaced with an alarming infection rate, growing ten times in just a month of hitting healthcare, education, and government systems with an exposed SSH server.

Discovered in August 2020, the malware is written in Golang and is considered to be a sophisticated threat that relies on custom code, runs in memory, and is decentralized -- peer-to-peer (P2P), so it does not need a central management server.
