11 Tips to Protect Against Ransomware Attacks

11 Tips to Protect Against Ransomware Attacks

Imagine working away on your PC and seeing a Windows update prompt. Instead of ignoring it, you take action. After all, you want to keep your device safe. But when you install what you think is a legitimate update, you're infected with ransomware .

That's the nightmare caused by an emerging cybersecurity threat.

Once ransomware infects your system, your PC is pretty useless. You must either pay a ransom or get someone to remove the malware and install a backup (if you have one!).

By 2031, it's expected a ransomware attack will occur?every 2 seconds .

A new threat that has emerged recently is the "Big Head" ransomware. It adds a new layer of deception by disguising itself as a Windows update.


The Big Head Ransomware Deception

Ransomware attacks have long been infamous for their ability to encrypt files. This renders them inaccessible to the victim until a ransom is paid to the attacker.

In the case of Big Head ransomware, the attackers have taken their tactics to the next level. The attack masquerades as a Windows update.

Big Head ransomware presents victims with a convincing and fake Windows update alert. Attackers design this phony alert to trick users. They think that their computer is undergoing a legitimate Windows update. The message may appear in a pop-up window or as a notification.

The deception goes even further. The ransomware uses a forged Microsoft digital signature. This makes the fake update appear more authentic and adds more credibility to the malicious message.

The attack fools the victim into thinking it's a legitimate Windows update. They then unknowingly download and execute the ransomware onto their system. From there, the ransomware proceeds to encrypt the victim's files. Victims see a message demanding a ransom payment in exchange for the decryption key.


Protect Yourself from Big Head Ransomware & Similar Threats

Cyber threats are becoming more sophisticated. It's crucial to take proactive steps to protect your data and systems. Here are some strategies to safeguard yourself from ransomware attacks like Big Head.

1. Keep Software and Systems Updated

This one is tricky. Updating your computer is a best practice for security. However, Big Head ransomware leverages the appearance of Windows updates.

One way to be sure you're installing a real update is to automate. Automate your Windows updates through your device or an IT provider. This increases the chances of spotting a fake that pops up unexpectedly.

2. Verify the Authenticity of Update

Before installing any software update, verify its authenticity. Genuine Windows updates will come directly from Microsoft's official website, your IT service provider, or Windows Update settings.

Be cautious of unsolicited update notifications, especially those received via email or from unfamiliar sources.

3. Backup Your Data

Regularly back up your important files. Use an external storage device or a secure cloud backup service. In the event of a ransomware attack, having backup copies is vital. Backups of your data can allow you to restore your files without paying a ransom.

4. Use Robust Security Software

Install reputable antivirus and anti-malware software on your computer. These programs can help detect and block ransomware threats. This helps prevent them from infiltrating your system.

5. Educate Yourself and Others

Stay informed about the latest ransomware threats and tactics. Educate yourself and your colleagues or family members. Discuss the dangers of clicking on suspicious links. As well as downloading attachments from unknown sources.

6. Use Email Security Measures

Ransomware often spreads through phishing emails . Put in place robust email security measures. Be cautious about opening email attachments or clicking on links. Watch out for emails from unknown senders.

7. Enable Firewall and Network Security

Activate your computer's firewall . Use network security solutions to prevent unauthorized access to your network and devices.

8. Disable Auto-Run Features

Configure your computer to turn off auto-run functionality for external drives. This can help prevent ransomware from spreading through infected USB drives.

9. Be Wary of Pop-Up Alerts

Exercise caution when encountering pop-up alerts. Especially those that ask you to download or install software. Verify the legitimacy of alerts before taking any action.

10. Keep an Eye on Your System

Keep an eye on your computer's performance and any unusual activity. If you notice anything suspicious, investigate immediately. Suspicious PC activity can be:

  • Unexpected system slowdowns
  • File changes
  • Missing files or folders
  • Your PC's processor "whirring" when you're not doing anything

11. Have a Response Plan

In the unfortunate event of a ransomware attack, have a response plan in place. Know how to disconnect from the network. Report the incident to your IT department or a cybersecurity professional. Avoid paying the ransom if possible.


Next Steps for Addressing Ransomware Risks

Solid security practices are the best defense against ransomware attacks. Once an attack takes root, there's no easy way to address it.

You may be able to avoid paying the ransom if the infection is contained and you have quality backups. However, paying the ransom does not guarantee system restoration.

Talk to your IT provider about running a?risk assessment ?to check for security vulnerabilities. You should also verify that you have an updated?IT incident response plan .

It is a red flag if your provider does not perform quarterly risk assessments or discuss incident response plans. Neglecting these two practices may mean your provider does not understand effective security practices and is putting you at risk.
