A New Ransomware Called Big Head, Disguises Itself as a Windows Update

Big Head is a new ransomware threat gaining traction. This new ransomware is targeting devices and encrypting their files through a deceptive Windows update alert. This malicious software operates by deploying three encrypted executable files during the attack process. One is responsible for propagating the malware, another facilitates communications via Telegram, and the third encrypts the files while displaying the fake Windows update.

If a user falls victim to this deceptive alert and clicks on it, Big Head initiates its attack by deleting backups, checking the virtualized environment, and disabling the computer’s Task Manager to prevent easy removal. Moreover, certain variants of Big Head ransomware have been found to be capable of stealing web browser history, directory lists, running processes, product keys, and network information. Incidences of this ransomware have been largely reported from the United States, France, Turkey, and Spain.

Here’s what you can do to prevent yourself and your business from ransomware attacks:

1. Update Your Cybersecurity Policies

Ensure all of your employees are up-to-date on the latest cybersecurity policies and procedures. Make sure they know not to click on any suspicious links or open any attachments that may contain malicious code.

2. Use Advanced Security Measures

Implement advanced security measures such as two-factor authentication, data encryption, and endpoint detection and response to protect against potential attacks. Invest in security software such as anti-virus protection, endpoint monitoring, and intrusion detection systems to help protect against potential threats. Additionally, use password managers to ensure all passwords are secure and regularly updated.

3. Be Aware of Phishing and Scam Emails

Be cautious with emails: Avoid opening emails from unfamiliar senders, as they may contain phishing attempts or malicious links. Even if you accidentally open such an email, refrain from clicking on any links or opening attachments. Cybercriminals often exploit this tactic to deceive users into believing the message is from a legitimate source.
