Ransomware is a new generation threat that uses a strong Encryption algorithm that encrypts the some or all your computer files.

   Hackers use Phishing Emails, RDP vulnerabilities and cracked software in order to enter your infrastructure.

    Then they launch the encryption trojan to lock your files while the malicious hacker has they only key to the decryption.

The Ransomware reseller or controller, after all your files are encrypted, asks you to pay a ransom payment in order to decrypt your files.

WannaCry, an encrypting ransomware computer worm. The ransom demand ranged from $300 to $600 to be paid in the cryptocurrency Bitcoin.

The Trojan targeted computers running Microsoft Windows, propagating via infected email attachments.

Εxamples of ransomware

Ransomware is a malware designed to deny a user or organization access to files on their computer. By encrypting these files and demanding a ransom payment for the decryption key, cyberattackers place organizations in a position where paying the ransom is the easiest and cheapest way to regain access to their files. Some variants have added additional functionality – such as data theft – to provide further incentive for ransomware victims to pay the ransom.

Ransomware sometimes deletes itself after it has infected a system, other times, it stays on a device to infect other devices or files. Use antimalware/anti-ransomware apps.

Can ransomware be removed ?

After a device is exposed to the malicious code, the ransomware attack proceeds as follows. 

Ransomware can remain dormant on a device until the device is at its most vulnerable, and only then it executes an attack.
