Old virus never dies — it just morphs into something more devious and dangerous — and this pattern is playing out with “Joker” malware, which was first identified in 2016. In 2020, it’s back and more diverse and devious than ever.
During the past few months, Joker has become one of the most active Android® virus infections. Joker rides on the coat-tails of seemingly legitimate apps, then covertly signs up users for pricey subscription services. It can also steal SMS messages, contact lists, and device information.
Joker variations seem to arrive in batches, with a fresh batch leeching onto dozens of aplicaciones as recently as September.
Joker Infiltrates The Apps Store
“One of the best ways to avoid virus and trojan aplicaciones is to use Google’s sanctioned app store,” says Emilio Simoni, PSafe’s dfndr lab Research Director, “but unfortunately, Joker has managed to disguise itself and mutate so profusely, that it has found its way on to several aplicaciones within the official Google® Play marketplace. Of course third party app stores are also offering Joker-tainted aplicaciones — so the best protection is going to be a strong security app that sniffs out malware-tainted aplicaciones immediately, like our dfndr security Pro.”
Google removes the offending aplicaciones as soon as they’re reported — but the high rate of variation and concealment with this peculiar trojan keeps bringing new specimens on board.
“Part of what makes Joker so effective is that it waits to take effect,” Simoni remarks. “After the trojan-app is downloaded (many of these are knockoffs of better-known apps) it waits to drop a very small packet of code, it then reaches out to the server that loads the virus that does all the dirty work.”
What Can You Do To Stay Safe?
Good hygiene with your digital devices includes:
- Installing only the aplicaciones that you need and use. Loading up your device with as many aplicaciones as you can imagine using is a hazardous path.
- Being wary. Look for aplicaciones from developers you know and trust. Do a little background checking and make sure that cool new app is coming from a known and trusted provider.
- Cleaning house periodically. To keep the number of aplicaciones you use to a minimum, do a periodic review of the aplicaciones on your phone and delete the ones you’re not using.
“Good security habits are always the first step,” Simoni observes, “but we can see that with truly devious virus like Joker, personal vigilance may not be enough. When a piece of virus is mutating on a monthly basis, you need a dedicated security solution to help keep you safe.”
The Best Defense Begins BEFORE Dangerous Apps Are Downloaded
An excellent way to protect yourself is to use a security application like dfndr security Pro, which has a dedicated Safe App Installer that can tell you if the app you’re about to install has been identified as malware. This is exactly what the Safe Apps Installer does: it AUTOMATICALLY protects you from virus and aplicaciones known to compromise your data — before you even install them.

Safe App Installer is only one of the key features dfndr security Pro offers. It also comes with a full suite of security capabilities that can protect you not only from digital threats, but from thieves “IRL” as well.
