RAR stands for Roshal Archive and is used for data compression, error recovery, and file spanning. It is required for us to employ the RAR file format, for file compression (.rar). Utilman is an accessibility application that can be executed before user login, often abused by hackers to bypass system authentication.TIPS AND TRICKS TO CREATE, SEND, AND OPEN RAR FILES ON WINDOWS 10 Introduction Password-protected SFX created with 7-ZipĬrowdStrike’s analysis discovered an adversary that used stolen credentials to abuse ‘utilman.exe’ and launch a password-protected SFX file that had been planted on the system previously. These files can be password-protected to prevent unauthorized access and simplify distribution of archived data to users who do not have a utility to extract the package. SFX files are essentially executables that contain archived data along with a built-in decompression stub, which is the code used for unpacking the data. By including harmless decoy files in the SFX files, attackers can plant backdoors without triggering the security agent on the target system. Researchers from cybersecurity firm CrowdStrike have discovered that hackers are adding malicious functionality to self-extracting archives (SFX) created with compression software like WinRAR or 7-Zip.
