Analysis Summary
AsyncRAT is an open-source tool designed for remote monitoring via encrypted connections. However, it could be utilized by threat actors as it provides keylogging, remote access, and other functionality that could damage a victim’s computer or system. This tool can be used to send malicious files to the system which once executed can be a source to other malicious software. These can also be used to transfer malicious programs into USB drives and can infect other systems.
Numerous malware campaigns and threat actors have utilized AsyncRAT in various recent attacks. More recently, a social engineering campaign that targeted Thailand pass (an online travel agency) consumers were observed. Additionally, the Follina Outbreak in Australia spread AsyncRAT as a malicious payload.
AsyncRAT can be delivered through a number of techniques, including spear-phishing, malicious advertising, exploit kits, and others.

Remediation
- Block all threat indicators at your respective controls.
- Search for Indicators of compromise (IOCs) in your environment utilizing your respective security controls
- Do not download document ?les attached in emails from unknown sources and strictly refrain from enabling macros when the source isn’t reliable.
- Enable antivirus and anti-malware software and update signature definitions in a timely manner. Using multi-layered protection is necessary to secure vulnerable assets
- Patch and upgrade any platforms and software timely and make it into a standard security policy.
- Enforced Access Management Policies.
- Along with network and system hardening, code hardening should be implemented within the organization so that their websites and software are secure. Use testing tools to detect any vulnerabilities in the deployed codes.
