What is Ransomware?
A ransomware is software that encrypts data on a computer and then demands payment from the victim to decrypt it. It works by infecting the computer and encrypting files, such as documents, spreadsheets, databases, etc. For example in one case a cyber-attackers encrypted over 300000 computers in just 24 hours. All the victim has to do is purchase the key to decrypt them. Once all the files are decrypted, they become useless and the edition of this malware produces a ransom note that says how much money (USD) they have to pay. However, most ransomware is designed with some kind of reward guarantee, so that after paying up, the cyber-attackers promise not to delete or copy the encrypted files. Thus, if you do not pay up this digital blackmailer will eventually delete these files after a while.
How Does Ransomware Spread?
Ransomware spreads primarily through email. The ransomware is distributed either by:
- an infected attachment that requires a victim to open, or
- a drive-by download attack, in which the ransomware is automatically installed when the victim visits a compromised website.
Ransomware attacks have increased significantly in recent years, primarily due to the availability of kits that make it much easier for cyber-attackers to develop new variations. Kit availability combined with the low cost and high return on investment makes ransomware attractive to criminals.
How Does Leex Ransomware Work?
Leex Ransomware locks the victim out of their system and displays a message demanding a ransom to be paid in Bitcoin, promising to decrypt the files if payment is made. Leex Ransomware, like other ransomware variants encrypts all files using AES-256 encryption key and RSA-2048 public key. Leex Ransomware then demands ransom payment of 0.1 BTC or approximately $710 USD in order for a private key to be provided that will allow decryption of the files including photos, documents, databases, etc. Leex ransomware contains no GUI (Graphical User Interface) but instead uses text messages displayed at random intervals demanding payment from the victim before it deletes all encrypted data on the system.

How to Protect My Computer From Ransomware
A way to protect your computer from ransomware is to use an anti-malware program or automatically run pre-installed security software when you boot up your PC. This will monitor your desktop and keep it safe from malware.
Another way to protect yourself from ransomware is by keeping regular backups of important data and storing them offline on a disc that cannot be accessed by the internet, which protects it from becoming encrypted and unavailable.
