| Verdict: | Malicious activity |
| Threats: | DeerStealer is an information-stealing malware discovered in 2024 by ANY.RUN, primarily targeting sensitive data such as login credentials, browser history, and cryptocurrency wallet details. It is often distributed through phishing campaigns and fake Google ads that mimic legitimate platforms like Google Authenticator. Once installed, it exfiltrates the stolen data to a remote command and control (C2) server. DeerStealer’s ability to disguise itself as legitimate downloads makes it particularly dangerous for unsuspecting users. |
