Level 33
A malware campaign distributing a new Backdoor Trojan named SpeakUp is currently targeting servers running six different Linux distributions and macOS by exploiting a number of known security vulnerabilities, while also managing to evade all anti-malware solutions in the process.

Backdoor Trojans are malware capable of providing attackers with access to compromised machines and to help them control those infected computers using commands sent via command-and-control (C&C) servers.

In most cases, this type of malware allows bad actors to run campaigns designed to operate covertly while giving the attackers as much control over the infected machines as possible, in most cases leading to a complete takeover.

According to Check Point, SpeakUp is a:

Backdoor Trojan that’s exploiting a server technology that runs 90%+ of the top 1M domains in the U.S. It also presented the ability to infect Mac devices with the undetected backdoor. It’s currently gaining momentum and targeting servers (70,000+ worldwide) -- first in East Asia and Latin America, including AWS hosted machines -- and with this, the U.S. could be the next target.
