Overview

Tar is a long-standing Unix/Linux archiving utility used to consolidate multiple files into a single tarball for storage or transfer. In cybersecurity, tar archives are commonly exploited to bundle payloads, stage exfiltration, or distribute multi-file toolchains, leveraging its ubiquity on Linux/Unix systems to blend in with legitimate activity. It also supports compression formats (gzip, bzip2, xz), which can aid in concealing data and payloads during transport.
