Bitcoin and Cyberattacks: How Ransomware Gangs Use BTC and Why Recovery Is Possible

Ransomware attacks — where hackers encrypt a victim’s data and demand payment for the decryption key — have become a major threat to individuals, businesses, and governments. The intersection of ransomware and Bitcoin is controversial: Bitcoin enables ransomware, but also enables tracing and recovery. Understanding both sides reveals a complex picture.

How Ransomware Works

The typical ransomware attack:

Infection: Malware is delivered via phishing email, vulnerable software, or compromised websites. The victim doesn’t know they’ve been infected.

Encryption: Once installed, the malware encrypts all accessible files: documents, databases, backups. The encryption is strong — typically AES-256 or RSA-4096.

** Ransom demand**: A message appears demanding Bitcoin payment (usually 1-10 BTC) in exchange for the decryption key. Payment is demanded within 24-72 hours, with the threat of deleting the key.

The lock screen: Some ransomware just locks the computer screen with the demand. Others a
