What is Crypto Malware?
Crypto malware is a type of ransomware that encrypts the victim's files, making them inaccessible. The malware then demands a ransom payment in exchange for decrypting the files. If the victim does not pay the ransom, the files are permanently lost.
How Does Crypto Malware Work?
Crypto malware typically spreads through phishing emails or malicious websites. Once the malware is installed on the victim's computer, it scans the computer for files that are important to the victim, such as photos, documents, and financial records. The malware then encrypts these files using a strong encryption algorithm, making them inaccessible.
What are the Different Types of Crypto Malware?
There are several different types of crypto malware, each with its own unique characteristics. Some of the most common types of crypto malware include:
- Locky: Locky encrypts files using the RSA-2048 encryption algorithm and demands a ransom payment of 0.5 bitcoins (approximately $2,000).
- CryptoLocker: CryptoLocker encrypts files using the AES-256 encryption algorithm and demands a ransom payment of 2 bitcoins (approximately $8,000).
- WannaCry: WannaCry is a ransomware that infects computers running Microsoft Windows. WannaCry encrypts files using the AES-128 encryption algorithm and demands a ransom payment of $300.
