Security News > 2023 > August > Cisco Talos Research: New Lazarus Group Attack Malware Campaign Hits UK & US Businesses

The Cisco Talos report exposes new malware used by the group to target Internet backbone infrastructure and healthcare organizations in the U.K. and the U.S. Two reports from cybersecurity company Cisco Talos provide intelligence about a new attack campaign from the North Korean threat actor Lazarus.

The researchers observed the Lazarus group successfully compromise an internet backbone infrastructure provider in the U.K. in early 2023, deploying a new malware dubbed QuiteRAT. The initial compromise was done via exploitation of the CVE-2022-47966 vulnerability, which affects Zoho's ManageEngine ServiceDesk.

Once the malware has been executed, it starts sending initial information about the system to its command-and-control server and waits for an answer, which might be a direct command to the malware or a Microsoft Windows command line to be executed via the cmd.

Lazarus has used various malware in this attack campaign: QuiteRAT, CollectionRAT, DeimosC2 and malicious Plink.

Although the group makes a lot of changes to its arsenal, the North Korean state-sponsored Lazarus threat actor "Continues to use much of the same infrastructure despite those components being well-documented by security researchers over the years," according to Cisco Talos.
