Delete WildFire Locker encryption trojan and dectypt .wflx data

WildFire Locker (.wflx file extension) is a piece of ransomware that hits users worldwide. It keeps operating systems available for access but applies a malicious encryption so that the victims cannot read most of the files. Moreover, the rogue scrambles file names. The victims cannot tell one piece of data from another.

The rogue has been around for quite a while. First IT security reports on the ransomware release dates back to the middle of June.
A number of infection vectors contribute to the success of the propagation. Some are rather region-specific. A good example would be a message composed in Dutch. It originates from the infamous Kelihos botnet. The scam used to push a Canadian pharma. A typical letter composed in Dutch would say the driver has failed to deliver a parcel. It prompts a user to create a new appointment by downloading and completing the form. The download triggers the ransomware installation instead. Again, the above infection vector originally spammed a pharma advertisement.

Once the invasion has completed the ransomware reports to remote server. IT security managed to intercept part of the communication. Unfortunately, the interception did not prevent delivery to the addressee. The remote server managed to dispatch further instructions for the compromised machines.
Nevertheless, the data enables to judge on the traffic origin. It shows most of the machines affected (up to 95%) reside in the Netherlands and Belgium.
It is not that WildFire Locker is a Dutch virus. The point is the distributors take hold of the propagation network that targets the corresponding region.
AES -256 CBC encryption launched by the ransomware is strong enough to withstand a straightforward attack. The infection avoids certain data formats. In particular, it omits system files so that your operating system may run. The hackers do not want that because they are so nice guys: unless the system operates, the victims are less likely to read the ransom note.
