Threats Tagged 'malicious domains'

An investigation into domains associated with the LummaC2 infostealing-malware campaign revealed a broader network of nearly 500 domains with highly malicious risk scores. These domains share similar registration patterns, including the use of Eastern European names and the inbox[.]eu email domain. The domains predominantly advertise technical education courses, but are likely lures for malware delivery. Four domains were identified as LummaC2 login panels. The campaign's infrastructure uses specific TLDs, naming conventions, and a Hong Kong address linked to OFAC-sanctioned entities. Security teams are advised to monitor for similar domain patterns, scrutinize suspicious training sites, and educate users about the risks.

A campaign targeting the Google Chrome Web Store has deployed over 100 malicious browser extensions masquerading as legitimate tools like VPNs, AI assistants, and crypto utilities. These extensions, while offering some promised functionality, secretly connect to threat actor infrastructure to steal user information and execute remote scripts. They can modify network traffic, deliver ads, perform redirections, and act as proxies. The campaign, discovered by DomainTools researchers, involves numerous fake domains promoting these tools. The extensions request permissions that enable cookie theft, DOM-based phishing, and dynamic script injection. Risks include account hijacking, data theft, and browsing activity monitoring. Some extensions remain on the Chrome Web Store despite Google's removal efforts.
