What is Novalock Ransomware?

Novalock ransomware encrypts files on infected systems and appends their filenames with the ".novalock" extension. For instance, a file named "example.jpg" becomes "example.jpg.novalock." Alongside the encryption, Novalock generates a ransom note titled "how_to_back_files.html," which provides instructions for victims to recover their data by paying a ransom.

Key Characteristics of Novalock Ransomware

• File Extension: Encrypted files are appended with ".novalock."
• Ransom Note: "how_to_back_files.html" explains the ransom demands and warns against using third-party decryption tools.
• Target Audience: Novalock predominantly targets businesses rather than individual users.
• Data Theft: The ransom note claims the attackers exfiltrate sensitive company data and threaten to leak it if the ransom is not paid.

How Novalock Operates

Upon infection, Novalock encrypts files using advanced cryptographic algorithms, making the data inaccessible without a decryption key. The ransom note provides the following details:

1. Warning Against Third-Party Tools: Attempts to modify or restore files using unauthorized software can render them undecryptable.
2. Ransom Payment: Victims are instructed to pay a ransom to recover their files. If contact is not established within 72 hours, the ransom amount increases.
3. Decryption Test: The attackers offer to decrypt three files free of charge to prove their capability.

How Does Novalock Spread?

Novalock ransomware typically infiltrates systems through phishing attacks and social engineering tactics. Common methods include:

• Malicious Email Attachments: Files disguised as legitimate documents with macros that trigger the infection.
• Fake Software Updates: Deceptive prompts encouraging users to download malicious files.
• Compromised Websites: Drive-by downloads from suspicious or hacked websites.
• Illegal Software Tools: Using cracked software or key generators.

Once inside, Novalock may spread laterally across a network, encrypting files and affecting multiple systems.

Consequences of Novalock Infection

• Encrypted Data: Files become inaccessible without the decryption key.
• Data Breach Threats: Sensitive company information may be leaked if the ransom is not paid.
• Financial Losses: Companies may face significant expenses due to ransom payments, downtime, and recovery efforts.
• No Guarantee of Recovery: Even after paying the ransom, there is no assurance that attackers will provide the decryption key.
