What is Ransomware?
As its name indicates, it is a malware that will kidnap the information on your computer and demand for money to release that information. In other words Ransomware is a type of malware that aims to extort money from victims by locking their data until they pay a ransom fee. The ransomware will typically encrypt important data stored on the victim’s device and show messages demanding payment in exchange for decrypting it. When a computer is infected with ransomware, the user can no longer use it because it is locked. The only way to unlock the device is to pay the ransom which can be anywhere from $200 to $2,000. Ransomware is also known by other names like Cryptoviruses, Cryptotrojans, Cryptoworms.
Type of Ransomware
There are two types of ransomware – crypto-ransomware and scareware. Crypto-ransomware encrypts the victim’s data files and demands a ransom for the decryption key. Scareware does not encrypt files but instead displays fake messages that scare users into paying money.
How does a Ransomware work?
Once it infects your computer, Ransomware will encrypt some or even entire list of files and then the attacker will start demanding money to get the decryption key from them get the data back. This encryption is so strong that without key there is almost no chance to recover the data. If you do not have a backup copy. And that backup also should be on another location (other then the same computer) which is not connected to the infected computer.
How does a Ransomware infect the system?
Mostly, Ransomware infects your computer via an infected program or through email attachments or even when you visit a malicious website. Ransomware attacks computers when the user opens an attachment from an unknown source or visits a malicious website. Even if you try to navigate away from the attachment Ransomware will initiate a drive-by download and infect your computer. Once it gets on to your computer it will search for common file types and when it locates them it encrypts the files and leaves a note on your computer saying that you have to pay a ransom to unlock the files.
A certain type of Ransomware will shut you out of an infected computer and will then display a banner that says that the victim has violated certain laws by viewing child pornography sites and therefore has to pay a ransom to unlock the computer. These are known as Police Trojans.
