    <name>RAR Encrypts and Deletes Files [B0601]</name>

    <category>Ransomware / Filecoders</category>

    <os>Windows</os>

    <severity>84</severity>

    <mitreattackid>T1560.001,T1486</mitreattackid>

    <explanation>A RAR archiver was executed, instructed to password-protect an archive, and delete the source files. If the user isn't aware of the activity, it may indicate ransomware activity.</explanation>

    <benignCauses>It can be a legitimate action of the user to protect data by encrypting it.</benignCauses>

    <maliciousCauses>Used by some filecoders to encrypt and delete a user's data.</maliciousCauses>

    <recommendedActions>1. Investigate the activity:

   * Is it a single activity or a sequence?

   * What is the count and type of files involved?

   * Was it initiated by the user or not?

2. What process initiated the activity?

   * Is it a well known and trusted program?

   * Is it signed by a trustworthy vendor?

   * Scan it with your Antivirus product or check its reputation and popularity directly in the Inspect console.

   * If suspicious, submit the program for further analysis.

3. Use the password from command line logged by Inspect to recover the encrypted files.</recommendedActions>
