“This action notably involves a marketing campaign probable concentrating on cryptocurrency people and businesses with a variant of the AppleJeus malware by way of destructive Microsoft Office environment paperwork,” researchers Callum Roxan, Paul Rascagneres, and Robert Jan Mora mentioned.
The North Korean authorities is identified to adopt a 3-pronged technique by utilizing destructive cyber activity developed to gather intelligence, conduct attacks, and create illicit income for the sanctions strike nation.
