Ransomware | |
Ransomware is malicious code that is used by cyber criminals to launch data kidnapping and lock screen attacks. The motive for ransomware attacks is monetary, and unlike other types of security exploits, the victim is usually notified that an attack has occurred and is given instructions for how to recover data. Payment for recovery instructions is often demanded in virtual currency to protect the criminal's identity. Ransomware malware can be spread through malicious e-mail attachments, infected software apps, infected external storage devices and compromised websites. In a lock screen attack, the malware may change the victim's login credentials for a computing device; in a data kidnapping attack, the malware may encrypt files on the infected device as well as files on other connected network devices. Ransomware kits on the dark web have allowed cybercriminals with little or no technical background to purchase inexpensive ransomware-as-a-service (RaaS) programs and launch attacks with very little effort. Attackers may use one of the several different approaches to extort digital currency from their victims. For example:
While ransomware attacks may be nearly impossible to stop, there are important data protection measures individuals and organizations can take to insure that damage is minimal and recovery is quick as possible. Strategies include compartmentalizing authentication systems and domains, keeping up-to-date storage snapshots outside the main storage pool and enforcing hard limits on who can access data and when access is permitted. |
