Malicious malware known as ransomware is a serious threat to people, companies, and organisations everywhere. It makes the data unavailable by encrypting the victim's files or locking them out of their own system. When the files are encrypted or access is lost, the attackers demand a ransom, typically paid in bitcoin. Ransomware can spread through a number of channels, such as phishing emails, malicious downloads, or through taking advantage of holes in networks or software. It frequently targets highly valuable information or crucial infrastructure, resulting in serious disruption and monetary losses. It is essential to frequently back up key data, keep software updated, apply strong security measures, educate users about phishing and strange links, and establish a thorough incident response strategy to limit the impact of ransomware to protect against it.
Example
Sarah, an employee at a small company, unknowingly opens an email attachment containing a disguised ransomware payload. The ransomware swiftly spreads throughout the company's network, encrypting critical files and rendering them inaccessible. The attackers demand a hefty ransom payment in exchange for the decryption key, putting the company's operations and sensitive data at risk until resolved.
