Cloudflare.exe is a malicious Windows PE masquerading as a legitimate Cloudflare-related binary. The sample is detected as malicious by 49/71 AV vendors and exhibits RAT-like behavior consistent with AsyncRAT/DcRat.

C2 communication evidence:
During execution, the malware contacts multiple external domains including
anayacarrentalcabbookings.in.net, www.anayacarrentalcabbookings.in.net, and www.fedramount.ru.com. These domains are atypical for legitimate software and are associated with suspicious infrastructure.

The observed outbound connections, combined with evasion techniques (debug checks, long sleep delays, obfuscation), strongly indicate active C2 communication used for remote command execution and botnet control.

Overall behavior confirms this sample as a RAT with active C2 infrastructure, not legitimate Cloudflare software.
