Operation MoneyMount, ISO Deploying Phantom Stealer
Source AlienVault OTX General
Description
Operation MoneyMount is a Russian phishing campaign targeting finance and accounting sectors by delivering Phantom stealer malware through fake payment confirmation emails. The attack uses a ZIP file containing an ISO image; when mounted, it reveals an executable that loads the stealer. Phantom stealer employs anti-analysis techniques and steals sensitive data including cryptocurrency wallets, browser data, and Discord tokens. It also features keylogging and clipboard monitoring to capture additional credentials and information. Stolen data is exfiltrated via Telegram, Discord webhooks, or FTP, making detection and blocking more challenging. The use of ISO files for initial access helps evade traditional security controls. This campaign highlights the growing sophistication of commodity stealers and the strategic targeting of financial sectors. No known exploits in the wild or CVE identifiers are associated with this malware yet. The campaign’s medium severity reflects its targeted nature and complexity of attack chain.
