The Russia-aligned group RomCom has exploited two zero-day vulnerabilities in Mozilla Firefox and Microsoft Windows to install their backdoor malware on victim systems without user interaction. The attacks utilize a fake website to redirect users, highlighting RomCom’s advanced capabilities and its history of cybercrime since 2022.
### Meeting Takeaways – Nov 26, 2024: Vulnerability / Cybercrime
1. **Threat Actor Identification**: The Russia-aligned group RomCom (also known as Storm-0978, Tropical Scorpius, etc.) has been linked to the exploitation of two significant zero-day vulnerabilities.
2. **Exploited Vulnerabilities**:
– **CVE-2024-9680**: A high-severity use-after-free vulnerability in Firefox’s Animation component (CVSS score: 9.8). Patched by Mozilla in October 2024.
– **CVE-2024-49039**: A privilege escalation vulnerability in Windows Task Scheduler (CVSS score: 8.8). Patched by Microsoft in November 2024.
3. **Attack Mechanism**:
– Victims navigating to a specific fake website (economistjournal[.]cloud) can trigger the exploit if using a vulnerable version of Firefox.
