G20 2014 Summit Lure used to target Tibetan activists

APT actors trying to use big events as a lure to compromise their targets is nothing new. Tibetan NGOs being targeted by APT actors is also nothing new.

Versatile and infectious: Win64/Expiro is a cross-platform file infector

Recently, our anti-virus laboratory discovered an interesting new modification of a file virus known as Expiro which targets 64-bit files for infection.

One such family of file viruses, called

Emotions are Poor Passwords
