“Cleaner Update” Popups on Android Phones are a Scam! Read This

In recent years, Android users have been increasingly targeted by a pervasive scam involving fake warnings about a “Cleaner Update” for their devices. This fraudulent message claims that the user’s device is infected with malware or running slowly, urging them to download a “fix” which is actually unnecessary software or worse – malicious adware or spyware.

This scam is rampant across the web, with popups and advertisements trying to trick users into downloading pointless or dangerous apps. Left unchecked, it can lead to device slowdowns, wasted money, and serious privacy and security issues.

In this article, we’ll break down exactly how the “Cleaner Update” scam works, who is behind it, and most importantly – how Android users can avoid falling victim. Read on for a deep dive into this persistent Android nuisance and what can be done to stamp it out.

Overview of the Scam

The “Cleaner Update” scam takes on a few different forms, but the core technique is the same across most variants:

• A popup, webpage, or advertisement warns the user of issues like malware infection, battery drain, or general slowdowns on their Android device.
• The message urges urgent action, saying the user must download a “cleaner” app or perform a system update to resolve these alleged issues.
• Links lead either to 1) Legitimate but unnecessary “optimization” apps, 2) Adware/spyware masquerading as system utilities, or 3) Scam sites asking for personal information.
• Regardless of the endpoint, the operator’s goal is to make money through app affiliate fees, ad clicks, or harvested user data. The apps/fixes either do nothing or actively harm the device.

Some example messages seen in the wild include:

“WARNING! Your Cleaner Update for Android is Available! We have detected that your Chrome is (62%) DAMAGED by Tor.Jack Malware…”

“Your Android is running slow! Download the FREE optimization tool now to speed up your device…”

“ALERT! Battery Drain Detected. Tap here to install the power-saving app and extend battery life…”

As you can see, these scam ads leverage fear and urgency to pressure users into tapping and downloading apps they likely don’t need. The surprising effectiveness of these social engineering tactics is what allows this grift to remain so common.

How the Scam Works

Now, let’s break down how the “Cleaner Update” scam operates from start to finish:

1. Displaying Fraudulent Ads to Users

The first step for scammers is getting their fake warning message in front of as many Android users’ eyes as possible.

To accomplish this, they will commonly:

• Purchase cheap banner/popup ad space through networks like Google AdSense.
• Take over abandoned apps or websites and fill them with their scam ads.
• Register malicious apps to the Google Play Store with their scam ad code hidden inside.
• Hack into sites with weak security and inject their scam message.
• Send the scam ads via SMS text messaging and social media spam campaigns.

In general, they are aiming for high-traffic channels with limited security – allowing their fake warnings to reach the most potential victims.

2. Making Scam Warnings Appear Urgent and Legitimate

Once they have a user’s attention, the scam operators will utilize known social engineering techniques to maximize likelihood of a tap/download:

• They pose as legitimate companies like Google or Android, abusing brand recognition.
• Technical jargon like “Tor.Jack Malware” or “62% DAMAGED” give the illusion of a real problem.
• Countdown timers, progress bars, and other elements convey false urgency.
• Official branding, stolen company logos, and secure padlock icons mimic legitimacy.

Combined, these tricks pressure and confuse users into believing the scam warnings are real – frightening them into tapping without thinking.

3. Redirecting Users to Download Unwanted Apps

When a user taps on one of their scam ads, where exactly does it lead? There are a few common endpoints:

Shady “Optimization” Apps

Many of the cleaner/battery apps linked in scam ads are real programs available on the Google Play Store. However, they generally provide little utility despite claims of speed boosts, battery life extension, and other benefits.

The scammers earn affiliate commissions when they trick users into downloading these apps. Even though they are legal, they are unnecessary bloatware for most people.

Adware/Spyware Apps

In other cases, the landing page links directly to malware masquerading as system utilities. Once installed, these malicious apps bombard the user with intrusive ads, quietly collect personal data, and even enroll the device into botnets.

Phishing/Survey Scam Sites

Finally, some scam ads lead to phony websites rather than apps. These sites mimic Android/Google and claim the user must fill out a survey or provide personal information before they can receive the “cleaner” fix. In reality, they are just harvesting data like emails and names to resell or exploit.

No matter the specific endpoint, the scammers’ objective is to profit off of tricking users through manipulation and deceit.

What to Do If You Are a Victim of This Scam

If you have fallen for the “Cleaner Update” scam, here are the key steps to get your device secured:

• Run antivirus scans – Use free antivirus apps like Malwarebytes to check for any spyware or adware infections. Remove anything harmful it detects.
• Reset browser settings – Browsers like Chrome may be configured to send traffic to scam sites. Reset them to default configurations.
• Change passwords – If you entered any account credentials on phishing sites, change your passwords immediately. Enable two-factor authentication if possible.
• Contact your bank – If you shared financial information, check for any fraudulent transactions and notify your bank right away.
• Remove unwanted apps – Carefully go through your installed apps list and uninstall anything unnecessary that may have been downloaded via these scams.
• Disable lock screen ads – Some malware will spam ads on your lock screen. Go into Settings and disable lock screen ads.

Staying vigilant and taking prompt action can help limit any potential damage from these scams. Be wary of any other suspicious ads or activity on your device afterward.
