What is Ransomware?
Ransomware is a type of malware that encrypts a victim’s data and demands payment, holding the data hostage until the ransom is paid.
This form of cyberattack employs sophisticated encryption techniques to lock the user’s files, making them inaccessible. Once the data is encrypted, the victim receives a message demanding a ransom, typically in cryptocurrency, in exchange for the decryption key. This creates a digital hostage situation where the victim’s data is essentially kidnapped until they comply with the demands.
Ransomware can have devastating consequences for individuals and organizations alike, resulting in data loss, financial damages, and reputational harm. To combat the threat of ransomware, advanced security software with robust encryption capabilities is essential. Businesses often invest in cybersecurity measures such as firewalls, antivirus programs, and intrusion detection systems to protect against ransomware attacks.
How Does Ransomware Work?
Ransomware operates by infiltrating a system through malicious emails or websites, deploying an encryption Trojan that locks files and demands a ransom payment for decryption.
Once the ransomware gains access to a system, it starts encrypting files using sophisticated cryptographic algorithms that render the data inaccessible without the decryption key. Cybercriminals typically use advanced encryption techniques such as RSA or AES to ensure that even security experts find it challenging to decrypt the files without the key. The encrypted files are often renamed with a unique extension to indicate they have been locked.
After encrypting the files, a ransom note is displayed to the victim, detailing the payment instructions and the deadline before the decryption key is destroyed. Cybercriminals usually demand payment in cryptocurrencies like Bitcoin to avoid traceability and anonymity.
