A new and particularly insidious type of ransomware, aptly named “Big Head,” has recently emerged. This ransomware ingeniously disguises itself as a Windows update, deceiving users into locking their files and having to choose between paying a ransom or losing their data. We’ll explain how this scam operates and the steps you can take to protect yourself.
Understanding the "Big Head" Ransomware
The Big Head ransomware poses a significant threat due to its deceptive approach. It mimics a Windows update, equipped with a fake Microsoft digital signature that appears surprisingly authentic. This sophistication is what makes it challenging to distinguish from a legitimate update. Once you install it, the ransomware encrypts your files, holding them hostage until a ransom is paid.
Protecting Yourself from Big Head and Similar Threats
Here’s your comprehensive guide to safeguarding against threats like Big Head:
Careful Software Updates: Regular updates are typically safe, but Big Head exploits this routine process. Automate your updates through your device settings or trust a reliable IT provider like Protek-IT to manage them, ensuring you only install genuine updates.
Verify Update Authenticity: Unexpected update notifications should always be met with scrutiny. Authentic Windows updates align with official Microsoft communications and are typically pushed through established channels.
Regular Data Backups: We recommend regularly backing up your important business data to a secure cloud service like SharePoint. This practice is your safety net, allowing you to restore your data without succumbing to ransom demands in the event of an attack.
Robust Security Software: Invest in reliable antivirus and anti-malware solutions — or rely on your Managed IT Services Provider, who will provide you with great managed antivirus software. These tools act as your first line of defense, identifying and neutralizing ransomware threats before they can cause harm.
Continuous Education: Keeping up-to-date with the latest ransomware trends is crucial! Regularly educate your team and family about the risks associated with clicking on suspicious links or downloading unknown attachments and the importance of cautious online behavior. We recommend conducting quarterly or monthly training for employees to ensure the highest levels of safety for your business data.
Email Security Measures: Phishing emails are a common distribution method for ransomware. Exercise caution with email attachments and links, especially from unknown or unverified sources.
Firewall and Network Security: Implementing a strong firewall and network security protocols is essential to deter unauthorized access to your system. These barriers can be critical in preventing ransomware from infiltrating your network.
Disable Auto-Run Features: Prevent your computer from automatically running programs from external drives, a common method for spreading ransomware. Adjusting these settings can significantly reduce the risk of inadvertently triggering malicious software.
Skepticism Towards Pop-Ups: Approach software download prompts, especially those that appear in pop-up alerts, with caution. Always verify their legitimacy before downloading – especially if a page has multiple “Download” buttons!
System Monitoring: Stay vigilant for signs of a ransomware infection, such as system slowdowns, unexpected file changes, missing files, or unusual noises from your computer when it should be idle. In case of any concerns, reach out to your MSP.
Prepared Response Plan: Having a plan in place for a suspected ransomware attack is crucial. Know the steps to take, including how to disconnect from networks and report the incident. Avoid paying the ransom, as it doesn’t guarantee the restoration of your files and can encourage further criminal activity.
