How Ransomware Works
Ransomware is a malware that sneaks on to a person’s computer through vulnerabilities in popular software, such as Java®, Adobe Flash® Player and other similar programs. It can invade a computer system when a user inadvertently downloads a Trojan from a phishing email or a drive-by download.
Once in, ransomware will encrypt files or lock the entire system of an infected computer, making files or the system inaccessible. Ransomware hijackers then demand users pay them to have their files decrypted or system unlocked.
Types of Ransomware
The most recent and persistent ransomware is Cryptolocker. Targeting computers running Microsoft Windows®, Cryptolocker encrypts files using RSA public-key cryptography, which relies on two digital keys – one public and one private. Cryptolocker stores the private key, which is needed to decrypt the files, until payment is received.
Another ransomware variant expected to hit the market soon is PowerLocker. According to security researchers tracking threats on underground forums, and reported by PCWorld®, PowerLocker appears to be more sophisticated. This new malware could turn out to be more dangerous than Cryptolocker, if speculation about its plans to be sold to cybercriminals is true. Time will tell.
