  • Unconventionial language used in binary resources: Arabic (Algeria);
  • Attempts to repeatedly call a single API many times in order to delay analysis time. This significantly complicates the work of the virus analyzer. Typical malware tactics!
  • Ciphering the documents found on the target’s hard disk drive — so the target can no longer use the data;
  • Preventing normal accessibility to the sufferer’s workstation. This is the typical behavior of a virus called locker. It blocks access to the computer until the victim pays the ransom.
