What is Ransomware?

Ransomware is malware or an occurrence associated with a deceptive message that is essentially used to procure currency from victims. There are many different forms of ransomware, different ransomware categories, and different variants of ransomware that can infect all types of devices including personal desktop computers, laptop computers, tablets, iPhones, and Android devices.

Most types of ransomware will encrypt personal files or will restrict access on an infected machine in order to force the victim to pay a ransom. The infection will usually leave a ransom note in .html format and text formats or utilize a lock-screen or image on Windows desktop that contains instructions to make a ransom payment in order to recover files or re-establish access to the restricted machine.

Ransomware is predominantly distributed by malicious email attachments, exploit kits, social media messages, and free downloadable content such as dubious torrent files, software updates, and game patches. In most the most common scenario, the malware author will orchestrate a mass email campaign that sends email spam to email accounts around the world. The email messages contain malicious email attachments that are usually in the .zip file format. The attachment might also be a fake document file for Microsoft Word. If contents of the .zip file are manually extracted by the user it will unpack a JavaScript file or VBScript Script file that when manually executed will spread the ransomware across the machine in a matter of time.

There are many variants of ransomware and many programs and lock-screens that are recognized as ransomware by Antivirus and Antimalware publishers. For example, a browser-lock screen that is essentially a full-screen advertisement can be considered ransomware because it will lock a browser window in place using an allotted number of iframes. The webpage will usually contain content demanding that a fine or payment be made in order to avoid some sort of consequence. Once the browser window is closed or the amount of allotted iframes is depleted there will no longer be an issue with this type of threat.

The most common types of ransomware are malware and computer viruses that can cause many issues with computers they infect. Ransomware like Locky usually encrypts files, randomizes file names or uses a pattern to change file names, appends a new file extension (such as zzzzz) to the files it encryptes, and leaves a ransom note and image of the ransom note in each file it encrypted files in and Windows desktop. The encryption process performed by this ransomware will render the files inaccessible to the user.

This particular infection will also change Windows desktop background to an image of a ransom note. The ransom note will explain what happened to the files and how to make a payment to the malware author.

Payments and ransom demands are usually different per each variant and type of infection. Some forms of ransomware will ask victims to email the malware author in order to make a payment or receive instructions, while others may ask victims to download Tor browser and visit a webpage on the darkweb.

Payment methods are also changing over time; although, they are mostly consistent with the use of Bitcoins and other similar online currency services. Payment systems like Greendot MoneyPak and others that were famous with infections around 2012 such as the FBI virus have become less used by malware authors over the years.

It is suggested to avoid paying  the ransom fines and malware authors to decrypt your files. Instead, third-party programs Shadow Explorer, PhotoRec, or Recuva can be used to possibly recover files encrypted by this type of infection. A user may also be able to retrieve encrypted files by performing a system restore to a date and time before the infection occurred or system recovery/reset.
