Setups of free programs.
Software installers, like drivers and other types of important programs.

Size: 805 KB

After the file is executed on the victim’s computer it may perform series of unwanted activities among the victim’s computer, starting with adding a scheduled task or a registry entry in Windows Registry Editor which both have the capability of running the file automatically in the future. The targeted registry sub-keys for this are believed to be the following:

→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce

%Documents%
%Desktop%
%Downloads%
%Music%

For the locking procedure, the developer of WANNACRYPT has likely taken the source code of a program which is similar to the programs Folder Lock or Doc Lock, which use simple encryption to lock folders and make them hidden, until the user enters a unique unlocking password.

After locking the folders on the victimized device, the WANNACRYPT virus sets the following ransom notes so that the victim knows of the virus’s presence:

Instructions from image:

“Your computer has been hacked and all your important files are now encrypted. To get back your all files you need to purchase the private key in Btcoin. Pay the EXACT amount to the Address given below
