Top Malware Families in 2023
In terms of malware families, Redline was by far the most popular (9205 detections), spotted more than twice as frequently as the second-most used malware Remcos (4407 detecitions). Redline is popular among cybercriminals because it’s easy to buy online and it can evade detection through polymorphic code, rootkit functionalities, and intricate obfuscation methods.
- Redline: 9,205
- Remcos: 4,407
- Agent Tesla: 4,215
- njRAT: 3,939
- AsyncRAT: 2,733
- FormBook: 2,098
- Amadey: 1,956
- Vidar: 1,569
Top MITRE ATT&CK techniques in 2023
MITRE ATT&CK is a widely recognized framework used globally. It categorizes various adversary actions into tactics and techniques. It’s an essential tool for malware analysts to identify, assess, and address threats more effectively.
ANY.RUN has a MITRE ATT&CK report that matches malware actions to specific techniques. In 2023, we made over 1.2 million matches, allowing us to put together this spreadsheet of TTPs adversaries employed most frequently in 2023:

Top TTPs: highlights:
- Masquerading Techniques (T1036.005): There’s a notable prelevance of Masquerading: Match Legitimate Name or Location technique. This indicates how common obfuscation via deceptive filenames and paths has been in 2023. This technique employs mimicry tactics to bypass heuristic detection. Effective countermeasures include behavioral analysis, focusing on anomaly detection in process tree execution and scrutinizing file path irregularities.
- Security Software Discovery (T1518.001): Software Discovery: Security Software Discovery is indicative of sophisticated adversaries targeting security mechanisms. This method is a hallmark of APTs and targeted ransomware campaigns.
- Increased Use of System Services for Execution (T1569.002): We’re seeing a lot of malware use system services to stay hidden and live of the land. This is a common technique in rootkits and sophisticated malware. This approach exploits system services to execute code at elevated privileges.
- Email Collection: Local Email Collection (T1114.001): This technique takes place with malware that focuses on stealing sensitive information from emails, specifically from local email files such as cache or Outlook files.
