Cyberthreats have been prevalent on the internet for decades now. Unfortunately, malware has been evolving more rapidly than the anti-malware software needed to combat it. The three most active cyberthreat categories worldwide are currently ransomware, phishing and endpoint attacks.
Ransomware is malicious software that encrypts data on a target system and demands a ransom in exchange for restoring access to the encrypted data. The demand is typically in Bitcoin and requires a digital key to unlock the files. These attacks range from low-level nuisances to serious incidents such as the data lockdown of several organizations.
