'Judy' Malware Potentially Hits Up to 36.5M Android Devices

Up to 36.five million Android devices may have been infected past malware that produced fake advertisement clicks and lined the pockets of its developers.

As outlined by security firm Check Bespeak, 41 apps developed by Korea-based Kiniwini and published under the moniker ENISTUDIO Corp., "infected devices to generate large amounts of fraudulent clicks on advertisements, generating revenues for the perpetrators backside information technology."

It's "possibly the largest malware entrada found on Google Play," according to Bank check Point.

Google "swiftly" removed the apps from Google Play after being alerted to their existence, Check Point says, but not before they "reached an amazing spread between 4.v one thousand thousand and eighteen.5 million downloads." Some were available on the store for several years and all were recently updated.

"It is unclear how long the malicious code existed inside the apps, hence the bodily spread of the malware remains unknown," Cheque Signal says, but those download numbers hateful "the full spread of the malware may have reached betwixt 8.5 and 36.five million users."

The malware was dubbed Judy by Check Point after the championship character in Kiniwini's apps. Chef Judy: Picnic Lunch Maker, for example, encourages players to "create delicious food with Judy." But Judy-themed games ran the gamut, from "Animal Judy" and "Manner Judy."

How does Judy infect your device? Hackers create an innocuous app that can go effectually Google's Bouncer security screening and is added to an app store.

"Once a user downloads a malicious app, it silently registers receivers which establish a connection with the [Command and Command] server," Check Point says. "The server replies with the bodily malicious payload, which includes JavaScript code, a user-agent string and URLs controlled by the malware author. The malware opens the URLs using the user agent that imitates a PC browser in a hidden webpage and receives a redirection to another website. Once the targeted website is launched, the malware uses the JavaScript code to locate and click on banners from the Google ads infrastructure."

Cheque Point likens Judy to two previous exploits: FalseGuide and Skinner. And similar some other bug, DressCode, Judy hid behind good reviews. "Hackers tin hide their apps' existent intentions or even dispense users into leaving positive ratings, in some cases unknowingly. Users cannot rely on the official app stores for their condom, and should implement advanced security protections capable of detecting and blocking zero-solar day mobile malware," Cheque Point says.

Kiniwini develops apps for iOS and Android, Check Bespeak says, merely it did not mention any problems with the iOS apps. Every bit of Sunday afternoon, 45 ENISTUDIO Corp. Judy apps are available in the App Shop, most of which appear to have terminal been updated on March 31.
