The main ransomware types:ĭepending on the peculiarities of the malware, IT experts classify file-encrypting threats into these categories: File Encrypting Ransomware To keep this data private, many organizations are forced to pay, even if they have backups to retrieve the encrypted files from. If victims do not agree to pay the ransom, malicious actors publish the stolen files for everybody to see. During this time, the attackers harvest sensitive documents and other information. Before deploying ransomware to encrypt data, the first snoop around, acquiring administrative privileges on the network, allowing lateral movement. While the first ransomware infections focused on locking users' computer screens and displaying a falsified FBI or other local authority messages, modern crypto-malware evolved to be more effective and efficient. In recent years, the cybersecurity landscape has seen a significant rise in this illegal business, as ransomware is becoming more lucrative.Ĭybercriminal gangs began employing another effective tactic that increased their success. Ransomware creators ask for ransom and that is where the term Ransomware has come from.ĭata locking process with a secure encryption algorithm such as RSA ensures that, if no backups were retained, files could only be recovered by paying the ransom in bitcoin (for anonymity purposes).
The main purpose of the attackers behind it is to extort money from companies, businesses, governmental institutions, and home users. Ransomware is a virus – a malicious program, that is designed to encrypt files on local and networked drives.
