In context: In concept, most malicious Android apps come from suspicious internet pages or third-party app shops, however safety researchers usually discover them hidden in Google’s official Play Store. A brand new report from Kaspersky suggests hacked Play Store apps are getting extra refined.
In a brand new report printed this week, safety firm Kaspersky describes a darkish internet market providing providers to hack targets with Android malware and spyware and adware. Hackers can sneak a lot of that malicious code onto the Google Play Store, circumventing Google’s most stringent protections.
The first step within the course of, and arguably probably the most harmful for finish customers, is hijacking Play Store developer accounts. A potential attacker will pay a hacker $25-$80 for a developer account that was both stolen or registered with stolen credentials. This lets cybercriminals convert beforehand trusted apps into vectors for malware.
If an attacker uploads a brand new app, they may not instantly load it with spyware and adware to keep away from drawing consideration from Google, however as a substitute, the technique is to attend till it accrues sufficient downloads. Hackers additionally supply providers to inflate obtain numbers and launch Google advert campaigns to make fraudulent apps seem extra reputable.
Then, hackers can use loaders to push malicious code to focus on units by way of seemingly reputable updates, however these won’t comprise the ultimate malware payload.
