Understanding Ransomware: A Primer
Ransomware is a type of malicious software (malware) designed to block access to a computer system or data until a sum of money is paid. Typically, the target’s files are encrypted, rendering them unusable. Cybercriminals then demand a ransom, often in cryptocurrency, to provide the decryption key. This form of cyber extortion can be significantly damaging to individuals and organizations alike.
The operation of ransomware often begins with a phishing email, which can contain a link or attachment that, when activated, installs the ransomware on the victim’s device. Once the installation is complete, the malware will begin encrypting files, often targeting sensitive documents, images, and databases. Some variants of ransomware also exfiltrate data before encryption, threatening to publish it unless the ransom is paid. This dual threat heightens the stakes for victims and complicates recovery efforts.
