The email, written in English, contains numerous grammatical, punctuation & spelling mistakes. The email further contains a compressed file as an attachment “COVID_19- WORLD HEALTH ORGANIZATION CDC_DOC.zip.arj”, which can be decompressed using 7-Zip.
ARJ compression format might be used due to the fact that it allows creating of very efficient compressed archives and is probably evasion tactic used by the threat actors. If the archive is opened, a file “DOC.pdf.exe” appears in front of the victim, which upon opening infects the machine with LokiBot malware.
