A pair of reports from cybersecurity firms SEKOIA and Trend Micro sheds light on a new campaign undertaken by a Chinese threat actor named Lucky Mouse that involves leveraging a trojanized version of a cross-platform messaging app to backdoor systems. Infection chains leverage a chat application called MiMi, with its installer files compromised to download and install HyperBro samples for the

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added two flaws to its Known Exploited Vulnerabilities Catalog, citing evidence of active exploitation. The two high-severity issues relate to weaknesses in Zimbra Collaboration, both of which could be chained to achieve unauthenticated remote code execution on affected email servers - CVE-2022-27925 (CVSS score: 7.2)

Networking equipment major Cisco on Wednesday confirmed it was the victim of a cyberattack on May 24, 2022 after the attackers got hold of an employee's personal Google account that contained passwords synced from their web browser. "Initial access to the Cisco VPN was achieved via the successful compromise of a Cisco employee's personal Google account," Cisco Talos said in a detailed write-up.

Threat actors associated with the Cuba ransomware have been linked to previously undocumented tactics, techniques and procedures (TTPs), including a new remote access trojan called ROMCOM RAT on compromised systems. The new findings come from Palo Alto Networks' Unit 42 threat intelligence team, which is tracking the double extortion ransomware group under the constellation-themed moniker

The new open source tools are designed to help defense, identity and access management, and security operations center teams discover vulnerable network shares.

Threat actors can abuse weaknesses in HTTP request handling to launch damaging browser-based attacks on website users, researcher says.
