Fiesta exploit kit’s authors have a new payload to deliver to their victims. Instead of crypto-malware and browser plug-ins, they are now using a rogue antivirus program that runs a fake system scan and tricks users into buying the full version of the product in order to remove non-existent threats.
The fake AV tool is dubbed Antivirus Pro 2015 and blocks certain Windows tools and similar software capable of deactivating it.

In their previous attacks, the hackers relied on the TeslaCrypt malware that is known for its file-encrypting capabilities.

TeslaCrypt affects games like World of Warcraft, Call of Duty, WarCraft 3, Minecraft, Assassin’s Creed, e altri.

The most targeted countries, according to Trend Micro’s research are:
- the USA – 36.9%
- Japan – 15.73%
- Australia – 11.9%
