AsyncRAT campaign exploits Cloudflare services to hide attacks

SCM feed for Latest

Researchers have identified a malware campaign utilizing AsyncRAT, a remote access tool, which is being cleverly masked by cybercriminals through Cloudflare's services. By using Cloudflare’s free-tier offerings and TryCloudflare tunneling domains, attackers are able to host malicious WebDAV servers. This tactic allows them to hide their operations behind a trusted infrastructure, making detection more difficult. The campaign raises significant concerns for organizations relying on Cloudflare, as it shows how legitimate services can be exploited for malicious purposes. Companies must remain vigilant and enhance their security measures to counteract such deceptive tactics that can lead to unauthorized access and data breaches.
