“Ransomware is a Cryptovirology attack carried out using covertly installed malware that encrypts the victim's files and then requests a ransom payment in return for the ecryption key that is needed to recover the encrypted files. Thus, ransomware is an access - denial type of attack that prevents legitima te users from accessing files since it is intractable to decrypt the files without the decryption key”.
Before ransomware was trendy among cyber-criminals, a malware infection was not a high priority for most users. Financial malware could be defeated via fraud detection, spammed Facebook walls were cleaned, and life could continue uninterrupted. Sometimes, the presence of the malware was not even noticed for months. But this has changed since ransomware became prevalent. The use of crypto-currencies like Bitcoin made it easy to cash out quickly. And because the malware has to only run for some minutes on the victim’s computer, most reactive protections failed quickly, and left the users unprotected against these cyber criminals. Multiple generic ransomware protection emerged to solve this issue.
Zemana Ltd. commissioned MRG Effitas to conduct a comparative analys is of its Zemana AntiMalware product, and other prevalent generic ransomware tools.
