A sophisticated phishing campaign leveraging trusted GitHub links has been identified, bypassing Secure Email Gateway (SEG) defenses and delivering malicious payloads. The campaign exploits the trust associated with GitHub, a popular platform for code sharing and collaboration, to distribute malware. Attackers are creating fake GitHub repositories with names resembling legitimate projects or organizations, enticing victims to download malicious files disguised as legitimate software updates or other files. This tactic effectively evades traditional security measures that rely on blacklisting known malicious domains or files. The use of trusted repositories for malware distribution underscores the importance of implementing robust security measures to protect against social engineering attacks and carefully verifying the authenticity of any software or files downloaded from external sources.

ESET researchers have uncovered two sophisticated toolsets developed by the North Korean APT group, GoldenJackal, specifically designed to compromise air-gapped systems. These toolsets, never before seen in the wild, highlight the group’s resourcefulness and commitment to targeting government and diplomatic entities in Europe, the Middle East, and South Asia. The advanced nature of these tools suggests that GoldenJackal has invested significant resources in developing specialized capabilities to bypass conventional security measures. This discovery underscores the importance of maintaining robust security protocols for critical infrastructure and sensitive data, especially in the face of persistent and sophisticated nation-state threats.

Microsoft Threat Intelligence has identified a growing trend of phishing campaigns exploiting legitimate file hosting services like SharePoint, OneDrive, and Dropbox to launch business email compromise (BEC) attacks. These campaigns leverage the familiarity of these platforms to deceive users, leading them to click on malicious links or open infected files, ultimately enabling attackers to compromise accounts and steal sensitive information. Organizations are advised to implement robust security measures to protect against BEC attacks, including multi-factor authentication (MFA), employee training on phishing awareness, and careful scrutiny of email communications, particularly those involving requests for sensitive information or financial transactions.
