| Verdict: | Malicious activity |
| Threats: | Ramnit is a highly modular banking trojan and worm that evolved from a file-infecting virus into a powerful cybercrime tool. It specializes in financial fraud, credential theft, remote access, and malware delivery, being a serious threat to businesses and individuals. First spotted in 2010, Ramnit became popular after the 2014 takedown of the GameOver Zeus botnet, as cybercriminals sought alternatives for banking fraud. |
