Locky is a type of ransomware. It was released in 2016 while security experts found that the malware authors delivered this ransomware via email asking for payment through an attached invoice of a malicious Microsoft Word document that runs infectious macros.

How Does Locky Ransomware Work?

The document when opened by the user would not be in a readable format and a dialog box opens with a phrase “Enable macro if data encoding is incorrect.” This is a simple social engineering technique to used as bait to trick the user and pass on the infection.

When the user enables the macros, the malware author runs a binary file which then installs the encryption trojan that locks all the files that have specific extensions. Later the filenames are changed to a combination of letters and numbers.

Once the files are encrypted, the locky ransomware demands to download the tor browser and enter a specific website which is actually malicious. It also demands to pay a ransom to unlock the encrypted file.

Why Xcitium Advanced Endpoint Protection?

Xcitium Advanced Endpoint Protection (AEP) is an ideal security solution that equips any business network with the right measure of security features. Case studies have proven that Xcitium AEP completely denies targeted attacks and APTs (advanced persistent threats) which cannot be made possible by a single standalone antivirus.

Endpoint protection solutions provide enterprises a centrally managed security solution to help secure workstations, endpoints- servers, etc.. which are connected to endpoints, and the endpoint devices.

It is considered to be the best, as it integrates antivirus, anti-spyware, firewall, and application control that features HIPS (host intrusion prevention) techniques – all in one single console.

It combines patch management, configuration capability, and vulnerability assessment to enable proactive protection of data files and disk encryption.
