Malware Laced Printer Drivers – PSW #875

Keypoints :

• Malware embedded in UV printer drivers can include backdoors and cryptocurrency stealers, often distributed via supply chain compromise on USB drives.
• Cross-site scripting vulnerabilities in mail servers like Zimbra and Hord have enabled attackers to exfiltrate credentials, manipulate email forwarding, and hijack sessions.
• Japan’s active cyber defense law aims to regulate offensive and defensive cyber operations, requiring oversight bodies and strict penalties for misuse of data.
• Undocumented cellular modems in solar inverters could potentially be exploited for malicious control, but evidence of malicious activity remains unconfirmed.
• Firefox’s recent out-of-bound promise object vulnerabilities, although minor in line count, demonstrate the importance of timely updates in open-source projects.
• Potential supply chain vulnerabilities in Avanti’s products stem from inherited code from multiple acquisitions, with CVEs highlighting security risks in their endpoint management systems.
• Legacy techniques such as in-memory shellcode execution remain effective against modern EDRs, emphasizing the ongoing challenge of detecting simplistic but effective malware methods.
