Final month, the FBI reiterated the hazards of “juice jacking,” an alleged observe whereby dangerous actors steal knowledge or set up malware in your smartphone by way of public chargers. The issue is, there have been no documented cases of juice jacking in the wild, which could lead some to think about digital safety warnings, say, about QR code scams, as one more tech ethical panic.
Nevertheless, QR code scams are actual, and you ought to be vigilant. However you shouldn’t freak out about them.
QR code scams within the information
Not too long ago, QR code scams have been making information. As reported by Bleeping Computer, scammers stole $20,000 from a girl in Singapore after she scanned a QR code purporting to be a survey for her native bubble tea store. The advert promised a free cup of milk tea for finishing the survey, so she scanned, and subsequently downloaded an app when prompted so as to take the survey. As you will have guessed, that app had nothing to do with the bubble tea store. It had all the pieces to do with putting in malware on her cellphone, and it stole $20,000 straight from the sufferer’s checking account.
Redditor hamsupchoi posted to r/sanfrancisco final week to warn different metropolis residents a few pretend parking ticket rip-off they caught. Their “parking ticket” regarded legit at first look, however sported a metropolis seal, one thing an actual parking ticket wouldn’t, and the QR code to “pay on-line” really gave up entry to the victims’ financial institution accounts.
And the Better Business Bureau highlighted a FAFSA scam wherein dangerous actors trick you into pondering they can assist you pay down your pupil loans. A QR code “helpfully” takes you to the official “studentaid.gov” web site, however, in fact, none of it’s actual, and all the cash you pay to the positioning goes to the scammers, not towards your loans.
How QR code scams work
For essentially the most half, there’s little or no threat to easily scanning a QR code alone. The place the hazard comes is what you do after scanning the code. Scammers would possibly design their QR code to put in a trojan horse in your machine, with the aim of stealing knowledge or working advertisements within the background. However they additionally would possibly draft an internet site that appears to be like like an official web site, however really steals data like your login credentials.
Think about one of many examples above: The sufferer scanned the QR code on the tea store, which lead her to a immediate to obtain a third-party app to her cellphone. That is pink flag primary: Don’t obtain an app from a QR code until you’re 100% certain the group behind the code is legit. That is the primary entry level for dangerous actors to get into your cellphone.
Nevertheless, the app alone wouldn’t have been capable of steal the $20,000 from the sufferer. As soon as she opened the app, it requested for permission to make use of her cellphone’s microphone and digicam, in addition to Android Accessibility Service. That final permission permits an app to take management of the display screen for accessibility functions, however, to dangerous actors, it’s a method into the sufferer’s life. From there, they had been capable of scrape the login credentials from the sufferer when she used her banking app, permitting them to entry their funds with out the sufferer’s information. Yikes.
In one other state of affairs, a QR code would possibly result in an internet site you consider to be authentic, the place you’d be prompted to enter your username and password—however whenever you attempt to log in, nothing occurs. That’s as a result of the “web site” is definitely pretend, present for the only objective of studying your login credentials. If a QR code is purporting to take you to a web site the place you will have an present account, like Amazon or your financial institution, navigate there your self as a substitute—or at the least affirm that the URL doesn’t look sus.
safely scan QR codes
So, are QR codes too harmful to scan? Under no circumstances.

However with the rise of QR code scams within the information, I believe there’s room for an additional tip to guard your self when scanning. Do not give permissions for something after scanning a QR code, and don’t obtain apps or information when prompted. 99% of the time, no matter is on the opposite finish of that QR code does not want entry to your cellphone’s digicam, microphone, location, or, worst of all, accessibility features. The menu at your favourite restaurant will just do superb with none of that, and dangerous actors gained’t have the ability to run their scams should you don’t give them the chance to take action.
