Bitter APT deploys PapRAT backdoor targeting South Asia

The Bitter cyber espionage group has deployed a previously unreported remote access trojan called PapRAT against South Asian organizations. PapRAT features both C++ and Rust implementations with capabilities including command execution and file operations. The backdoor represents a new tool in Bitter's ongoing cyberespionage campaign. Organizations in South Asia should monitor for indicators of compromise and strengthen endpoint detection capabilities.
