"A 20-year-old Trojan resurfaced recently," reports Dark Reading, "with new variants that target Linux and impersonate a trusted hosted domain to evade detection." Bifrost is a remote access Trojan (RAT) that's been active since 2004 and gathers sensitive information, such as hostname and IP address, from a compromised system. Moreover, there is evidence that cyberattackers aim to expand Bifrost's attack surface even further, using a malicious IP address associated with a Linux variant hosting an ARM version of Bifrost as well, they said...
