Traditional antivirus or end-point security based on a signature database cannot detect ransomware attacks. Attackers can create ransomware and tailor malicious code to be unpredictable and undetectable by current security solutions. Critical IT infrastructure suffers from zero-day attacks that target many computers around the world and have an impact on data privacy such as reputation damage, data leaks, and business loss that can be encrypted and not accessed by the authorized party unless a ransom payment is paid; however, it is impossible to recover the encrypted data.

Antivirus signature-based detection is likely to detect many known attacks, but it becomes ineffective against new sophisticated attacks. Many theoretical solutions have been proposed by researchers, with a focus on using a deep learning algorithm to detect and analyze patterns, whether malicious or benign software.[DSA1]
