Ransomware is a type of malicious software designed to deny access to a computer system or its files until a ransom is paid. This form of malware encrypts files on the victim’s computer, rendering them inaccessible, and demands payment for the decryption key. As a growing threat in the cybersecurity landscape, ransomware can inflict severe damage on both individuals and organizations. One such ransomware variant is Cicada 3301.
Cicada 3301 Ransomware: An Overview
Cicada 3301 ransomware is a particularly insidious form of malware that has gained notoriety for its sophisticated encryption techniques and demanding ransom schemes. Once installed, Cicada 3301 begins its attack by encrypting files on the infected system. Typically, this ransomware uses the file extension .cicada to mark encrypted files, making them inaccessible to the user.
How Cicada 3301 Ransomware Functions
Cicada 3301 infiltrates systems primarily through malicious email attachments, software vulnerabilities, or compromised websites. Once executed, the ransomware encrypts files using advanced encryption algorithms, making them unreadable without the decryption key. The encrypted files are often appended with the .cicada extension.
After the encryption process, Cicada 3301 leaves behind a ransom note in the form of a text file or a pop-up window. This note provides detailed instructions on how to pay the ransom, usually in cryptocurrency, to receive the decryption key. The note may also threaten to permanently delete the encrypted files if the ransom is not paid within a specified time frame.

Victims of Cicada 3301 ransomware typically notice several symptoms:
- Inaccessibility of Files: Files with the
.cicadaextension become unreadable. - Ransom Note: A text file or pop-up window appears, detailing payment instructions.
