SparrowDoor Backdoor Variants Target US and Mexico

New SparrowDoor Backdoor Variants Found in Attacks on U.S. and Mexican Organizations

Cybersecurity researchers have identified two new, more sophisticated variants of the SparrowDoor backdoor used by the China-linked threat group FamousSparrow. These updated malware versions, discovered during July 2024 attacks on organizations in the U.S. and Mexico, feature enhanced capabilities like modularity and parallel command execution, alongside improved anti-detection techniques. This campaign also marked the first observed use of the ShadowPad malware by FamousSparrow, a tool commonly associated with other Chinese APT actors, suggesting potential resource sharing. The attacks exploited vulnerabilities in outdated Microsoft systems to deploy these backdoors, enabling persistent access, command execution, and data theft. Organizations are urged to update systems and implement advanced security measures to defend against this evolving threat. ... Read More

MFA bypassing techniques

Hackers Using Advanced MFA-Bypassing Techniques to Gain Access to User Accounts

How cybercriminals are employing sophisticated techniques to bypass multi-factor authentication (MFA), a security measure designed to prevent unauthorized account access. These methods exploit vulnerabilities in the authentication process itself, such as manipulating session tokens and utilizing transparent phishing, rather than directly targeting passwords or one-time codes. The consequences of successful MFA bypass include minimal forensic evidence and difficulty in detection, potentially leading to data theft. To defend against these evolving threats, the text recommends strategies like continuous MFA validation, the use of cryptographically signed tokens, and the adoption of phishing-resistant authentication method. ...
