An unidentified hacking group is believed to have implanted a Cobalt Strike backdoor inside a localized font package that is downloadable on the President of Myanmar’s website. The initial incident was discovered by security researchers working for ESET and reported on June 2nd. The font package contained a file called Acrobat.dll containing a loader for the Cobalt Strike Beacon.
