DETECTION OVERVIEW
Risk Factors
AsyncRAT and AsyncRAT variants are open-source malware that are easily accessible to attackers. This malware infects systems through user interaction, such as clicking phishing links or malicious ads. After a device is compromised, an attacker can remotely control the device, move laterally, or deploy secondary payloads and exfiltrate sensitive business information from the victim.
Category

AsyncRAT variants include DcRAT, XiebroRAT, SantaRAT, and VenomRAT. These tools establish a secure C&C channel from a victim device by initiating a TLS connection to an attacker-controlled server. During the session negotiation, the C&C server presents a certificate with hardcoded parameters that identify the traffic associated with AsyncRAT or variants. By establishing a successful encrypted session, the attacker can remotely perform malicious activities, including credential theft, file exfiltration, keylogging, and screen capturing.
