What Is Ransomware?
Ransomware Is A Form Of Malicious Software Designed To Deny Access To A Computer
System Or Files Until A Sum Of Money, Or Ransom, Is Paid By The Victim
Ransomware is a form of malicious software designed to deny access to a computer system or files until the victim pays a sum of money, or ransom. This type of cyber attack encrypts the victim's data, rendering it inaccessible, and the attacker typically demands payment in cryptocurrency to provide the decryption key or restore access. Ransomware attacks have evolved in sophistication, employing various tactics to exploit vulnerabilities in systems and networks.
The Ransomware Attack Process
Infiltration: Ransomware typically enters a system through phishing emails, malicious attachments, or exploiting software vulnerabilities. Once inside, it may employ various techniques to propagate and elevate privileges, enabling widespread impact.
Encryption: After gaining access, the ransomware encrypts files on the victim's system, making them inaccessible. Advanced ransomware variants use strong encryption algorithms, making decryption without the specific key nearly impossible.
Ransom Demand: Following encryption, the attacker presents a ransom demand, often in the form of a ransom note displayed on the victim's screen. Payment is usually requested in cryptocurrency like Bitcoin to maintain anonymity.
Data Exfiltration (Double Extortion): Some ransomware groups adopt a double-extortion strategy, threatening to release sensitive data unless the ransom is paid. This adds an extra layer of pressure on victims to comply.
Payment and Decryption: If the victim chooses to pay the ransom, the attacker provides the decryption key. However, paying the ransom is discouraged by law enforcement and cybersecurity experts as it does not guarantee the recovery of files and encourages further criminal activities.
