What is ransomware?

Ransomware is a malicious code that is used by cybercriminals to launch data kidnapping OR hacking and screen lock attacks. The motive for ransomware attacks is monetary, and unlike other types of attacks, the victim is usually notified that an exploit has occurred and is given instructions for how to recover from the attack.in this attack, Payment is often demanded in virtual currency to protect the criminal’s identity.

Ransomware malware can be spread through various malicious like 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 or may useless files on the infected device as well as other connected network devices.

Ransomware kits on the deep 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 several different approaches to extort digital currency from their victims. For example:

The victim may receive a pop-up message or email warning that if the ransom is not paid by a certain date, the private key required to unlock the device or decrypt files will be destroyed.

The victim may be duped into believing he is the subject of an official inquiry. After being informed that unlicensed software or illegal web content has been found on his computer, the victim is given instructions on how to pay an electronic fine.

The attacker encrypts files on infected computed devices and makes money by selling a product that promises to help the victim unlock files and prevent future malware attacks.

How to Protect Yourself From Ransomware Attacks?

To protect against ransomware attacks and other types of cyber extortion, experts urge users to backup computing devices on a regular basis and update software — including anti-virus software — on a regular basis. End users should beware of clicking on links in emails from strangers or opening email attachments and victims should do all they can to avoid paying ransoms.

While ransomware attacks may be nearly impossible to stop, there are important data protection measures individuals and organizations can take to ensure that damage is minimal and recovery is a 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.
