Recent findings from the cybersecurity firm Zimperium has revealed a worrying phenomenon: the infiltration of malicious applications into the Google Play Store through files of Android Package (APK) with incompatible compression methods.
A report was also recently filed method used by hackers to infiltrate malicious apps into the Play Store Similar to this, users should take precautions to avoid installing malware-infected tools on their devices.
Thousands of malicious apps infiltrate the Google Play Store using APKs

The Google Play Store has long been considered a bastion of security in the mobile app ecosystem, thanks to its rigorous controls and review policies. However, Threat actors have found a clever way to bypass these defenses using APK files with unknown or incompatible compression methods.
According to Zimperium researchers, at least 3,300 artifacts that make use of these compression algorithms have been identified in the digital world. Surprisingly, 71 of these samples can be installed on operating systems without any apparent problems.The question that immediately arises is: how do the attackers manage to carry out this infiltration?
The answer lies in the distribution of these applications outside of the Google Play Store. There is no evidence to suggest that these apps were available in the official store at no time.
Instead, they are spread through untrusted channels, such as third-party app stores, or by using social engineering techniques to persuade victims to install them from external sources. This distribution method avoids the security review that Google This applies to applications that are added to their store.
Furthermore, these malicious applications employ an unsupported compression technique in their APK files, which limits the ability of decompilation tools to analyze their contents. Essentially, these apps camouflage themselves under a layer of protection that makes them resistant to deconstruction and analysis., which complicates early detection.
Zimperium launched its own investigation following a report about an APK file exhibiting this behavior, published by Joe Security in June 2023. This event underscores the constant evolution of tactics employed by cybercriminals to circumvent digital defenses..
Warning! Malicious actors are using sneaky techniques like versioning to bypass # Google Play Store's malware detection. Their goal is to steal users' credentials, data, and finances.
