A Trusted QR Code Scanner – Trend Micro QR Scanner
Author: Trend Micro
This article is from Trend Micro.
Since the very beginning of the COVID-19 pandemic, people and businesses started to value technology that facilitates contactless transactions more and more, and perhaps none of these technologies has proven more essential than QR codes. For contact tracing purposes, the technology has been essential.
To read the information contained in a QR code, you need a QR code scanner. However, many people don’t realize the sheer number of fake and malicious QR code scanners that are out there – any one of which could potentially cause serious harm to your digital life.
Hidden in plain sight
A malicious QR scanner can easily pretend to be a legitimate one. Unfortunately, on the surface, it can be nearly impossible to tell a malicious app from a real one, so people have no reason to not feel safe while the app is quietly spying on them and stealing their information. Malicious apps can remotely turn on your mobile’s camera and display ads on your phone’s screen even when the fake QR app is not in use.
Last year, Trend Micro detected two QR scanner apps on the Google Play Store that were malicious. To maintain the illusion of legitimacy, the apps worked as expected, but once closed, they would continue to function in the background, displaying ads on the screen periodically.
When an app turns evil
Even legitimate QR scanners sometimes turn rogue. Last year, an app named Barcode Scanner was taken down from the Google Play Store after it was discovered to be malicious. After receiving an update, it suddenly began to behave abnormally, displaying huge amounts of advertisements on the devices of its 10 million users. Users had absolutely no reason to believe the app was unsafe because from its initial release to the day it received the malicious update, there were no signs it would turn rogue. From this example alone, it is clear that a “safe” app that we may trust today, can easily become a threat in as little time as it takes to install an update.
When choosing the right QR scanner, consider opting for one that doesn’t include third-party ads. It’s also a great idea to choose one that’s published by a company with a long history of being a trustworthy app developer. Trend Micro QR Scanner more than fits the bill.

As the influence of the internet rises, so does the prevalence of online scams. There are fraudsters making all kinds of claims to trap victims online - from fake investment opportunities to online stores - and the internet allows them to operate from any part of the world with anonymity. The ability to spot online scams is an important skill to have as the virtual world is increasingly becoming a part of every facet of our lives. The below tips will help you identify the signs which can indicate that a website could be a scam. Common Sense: Too Good To Be True When looking for goods online, a great deal can be very enticing. A Gucci bag or a new iPhone for half the price? Who wouldn’t want to grab such a deal? Scammers know this too and try to take advantage of the fact. If an online deal looks too good to be true, think twice and double-check things. The easiest way to do this is to simply check out the same product at competing websites (that you trust). If the difference in prices is huge, it might be better to double-check the rest of the website. Check Out the Social Media Links Social media is a core part of ecommerce businesses these days and consumers often expect online shops to have a social media presence. Scammers know this and often insert logos of social media sites on their websites. Scratching beneath the surface often reveals this fu
How do I recover my crypto after it’s stolen? What happens if your crypto wallet is compromised? Can stolen crypto be traced, and can police actually recover crypto in 2026? These are the questions most people ask within minutes of realizing their wallet has been drained. Crypto theft is fast, quiet, and unforgiving. By the time most victims notice something is wrong, the funds are already moving across the blockchain. Once seen as a problem for exchanges and whales, crypto theft now heavily affects everyday investors. Phishing links, fake support chats, wallet approval scams, SIM swaps, and malware attacks have become common. Knowing what recovery realistically looks like—and what it doesn’t—can prevent panic, bad decisions, and costly follow-up scams. In a Nutshell Crypto recovery is possible, but only in limited situations Blockchain transactions are irreversible, but stolen crypto can still be traced Speed and documentation matter more than optimism Police and exchanges play a bigger role than private recovery services Guaranteed recovery offers are almost always scams Is it Actually Possible to Recover Stolen Crypto? Yes, crypto recovery is possible, but only under specific conditions and rarely through direct action by the victim. Blockchain transactions are final by design. Once crypto is sent and confirmed, it cannot be reversed. There is no central authority, no chargeback process, and no technical “undo” button, even if the transaction was clearly fraudulent. This is where many people ask whether stolen crypto can be traced. In most cases, it can. Every transaction
