Don’t Be Fooled! Popular Security Apps Can Go Rogue – Here’s What to Look Out For

We’ve all felt it: the almost instinctive urge to trust popular apps. Nothing wrong with that! Unfortunately, in the realm of online security, it doesn’t always pay off. As recently featured on the “Smashing Security” podcast, some so-called security apps can actually leave you vulnerable. So, how do you know when it’s time to draw the line?

What Is a Security App?

A security app is a type of software designed to protect your online accounts, such as email, banking, and social media from malicious hackers. Security apps use encryption, authentication, and authorization systems to help keep your data and accounts secure. Popular security apps include antivirus programs, password managers, and two-factor authentication (2FA) systems.

What Are the Risks of Rogue Security Apps?

The main risk of rogue security apps is that they can leave your accounts vulnerable to hackers and other cyber criminals. Even if the app has good intentions, the code can be outdated, buggy, or even malicious. In the “Smashing Security” podcast, encryption expert Bruce Schneier explains how attackers can use “rogue security apps” to exploit users.

The two main ways attackers do this are by injecting malicious code into the app, or by exploiting outdated code that hasn’t been updated to protect against new threats. Both of these methods can open up your accounts to data theft or unauthorized access.

So, How Do You Avoid Rogue Security Apps?

The best way to avoid rogue security apps is to do your research before downloading any type of software. Here are some steps you can take to protect yourself:

1. Read Reviews: Before downloading a security app, read reviews from other users. If the reviews are positive, it’s a good sign. But if they’re negative, it’s best to look for another option.

2. Check For Updates Regularly: Make sure you update your apps regularly to ensure they have the latest security patches. This is especially important for mobile security apps.

3. Look For An End-to-End Encryption: End-to-end encryption means that all data is encrypted, both in transit and at rest. This is important to protect your data from prying eyes.

4. Use Open Source Software: Open source software is a great way to protect your data from rogue apps. Open source software is developed in the public, meaning it can be easily audited and investigated for potential security risks.

5. Be Cautious: It’s always important to be careful when downloading any type of software. Don’t trust apps with sensitive data, such as your banking information, unless you’re sure they’re secure.


Security apps can be a great way to protect yourself online. However, it’s important to be aware that they can also be malicious and can potentially leave your data vulnerable. By doing your research, staying up to date on software updates, and being cautious, you can protect yourself from rogue security apps.
