Criminals are exploiting your trust in secure messaging apps to spy on you. As we’ve detailed in our **recent security alerts**, there is a wave of malicious spyware disguised as legitimate apps like Signal and ToTok. This guide is your definitive checklist for spotting these fakes before they can do any harm.

Part 1: The Pre-Installation Checklist — 4 Things to Check BEFORE You Install

The best way to win the fight is to never let the enemy onto the battlefield. Before you install any app, especially a security-sensitive one, perform this 4-step check.

1. Check the Source: Is it the Google Play Store?

This is the only question that truly matters. If the link you clicked took you to a website to download an `.apk` file, **STOP. DO NOT INSTALL IT.** It is almost certainly malware. Legitimate developers distribute their apps through the official Google Play Store.

2. Check the Developer Name

In the Google Play Store, look directly under the app’s name. For a legitimate app, you will see the official developer’s name. For Signal, it should say **”Signal Foundation.”** If it says “Signal Secure LLC,” “Signal Private Messenger,” or anything else, it is a fake.

3. Check the Reviews and Download Count

Look for signs of fakes. A globally popular app like Signal will have millions of downloads and a mix of good and bad reviews. A fake app will often have a suspiciously low download count (e.g., 5,000 downloads) and a flood of generic, 5-star reviews with no detail. This is a major red flag.

4. Check the “About this app” Permissions

In the Play Store listing, scroll down and tap on “About this app,” then look for “App permissions.” Does a simple messaging app need to be a “Device Administrator”? No. Does it need to “draw over other apps”? Not usually. If the permissions seem overly broad or suspicious, do not install it.

Part 2: The Post-Installation Audit — 3 Ways to Check Your Phone NOW

If you’re worried you may have already installed a fake app, perform this 3-step audit immediately.

1. Verify with the Play Store

This is the most definitive check. Go to the **Google Play Store > [Your Profile Icon] > Manage apps & device > Manage**. This list shows all apps on your phone that were installed from the Play Store. If your Signal app is **NOT** on this list, you sideloaded it. **UNINSTALL IT IMMEDIATELY.**

2. Audit Your Permissions Manager

Go to your phone’s **Settings > Apps > Permission manager**. Go through each category (`Camera`, `Location`, `Microphone`, `Files`). Do you see any apps in these lists that shouldn’t be there? A simple calculator app should not have access to your camera or location. Revoke any permissions that seem suspicious.

3. Run a Full Security Scan

The only way to be certain your device is clean is to scan it with a high-quality mobile security tool.

Your Digital Bodyguard: You can’t be expected to be a security expert 24/7. Let a tool do the work. Kaspersky for Android is our top-rated solution for automatically detecting and blocking trojanized apps, malicious links, and mobile spyware.

Chapter 3: The Golden Rule That Protects You From Everything

All of these checks are useful, but they all support one single, unbreakable rule of Android security:

Only install applications from the official Google Play Store. Period.

The Play Store is not perfect, but it has a massive, multi-layered security vetting process that blocks the vast majority of malicious apps. The moment you enable “Install unknown apps” and sideload an APK from a website, you are stepping out of that protected ecosystem and putting your data, your privacy, and your finances at extreme risk.
