Judy Android Malware: Οι ερευνητές ασφαλείας της Checkpoint ισχυρίζονται ότι ανακάλυψαν ενδεχομένως τη μεγαλύτερη καμπάνια malware στο Google Play Store, από την οποία έχουν ήδη μολυνθεί περίπου 36,5 εκατομμύρια συσκευές Android με λογισμικό ad-click.
Checkpoint blogged over 41 Android apps from a Korean company on the Google Play Store that are reportedly earning money for their creators by generating fake ad clicks from the infected devices.
All malicious applications, developed by Korea-based Kiniwini, were released under the name ENISTUDIO Corp and contained an adware program called "Judy" by researchers. Judy, as we mentioned earlier, was used to generate false clicks aimed at generating advertising revenue.
In addition, researchers also uncovered some other apps, which were published by other developers in the Google Play Store, and inexplicably contain the malware itself.
The connection between the two campaigns remains unclear, although researchers believe it is possible that one developer borrowed the code from the other, "knowingly or unknowingly".
"It is very unusual to find an organization behind a malware campaign, as most of them are developed purely by malicious (standalone) users," say CheckPoint researchers.
Apps available on the Play Store do not contain malicious code to bypass Google Bouncer protection.
The malicious apps appear to be actually legitimate gameα, αλλά στο παρασκήνιο λειτουργούν σαν γέφυρα για τη σύνδεση της συσκευής του θύματος με τον διακομιστή adware.
Once the connection is established, malicious applications corrupt the user agents of the browser to "play" the browser to open pages and generate clicks.
The following is a list of malicious applications developed by Kiniwini (click on "Malicious Applications" to open the list). If you have any of these installed on your device, remove it immediately:
Google has already removed the above apps containing Judy Android Malware from the Play Store, but since Google Bouncer did not recognize them as a malicious thing at the outset, it would be to watch what you downloaded.
