Threat actors are taking advantage of Android’s WebAPK technology to trick unsuspecting users into setting up malicious web apps on Android phones that are developed to capture sensitive own data.
“The attack started with victims receiving SMS messages suggesting the need to update a mobile banking application,” researchers from CSIRT KNF reported in an investigation unveiled final week. “The backlink contained in the message led to a website that used WebAPK technology to install a destructive software on the victim’s machine.”
The application impersonates PKO Lender Polski, a multinational banking and economic solutions business headquartered in Warsaw. Details of the campaign were very first shared by Polish cybersecurity agency RIFFSEC.
WebAPK permits end users to set up progressive web apps (PWAs) to their house display screen on Android devices with out having to use the Google Perform Retail store.
“When a user installs a PWA from Google Chrome and a WebAPK is utilized, the minting server “mints” (deals) and signs an APK for the PWA,” Google describes in its documentation.
“That method will take time, but when the APK is ready, the browser installs that application silently on the user’s gadget. Since dependable providers (Perform Services or Samsung) signed the APK, the phone installs it without having disabling security, as with any app coming from the keep. There is no will need for sideloading the app.”
At the time mounted, the fake banking app (“org.chromium.webapk.a798467883c056fed_v2”) urges people to enter their credentials and two-factor authentication (2FA) tokens, effectively ensuing in their theft.
“One particular of the issues in countering this kind of attacks is the fact that WebAPK programs create distinctive package deal names and checksums on just about every machine,” CSIRT KNF said. “They are dynamically designed by the Chrome engine, which helps make the use of this info as Indicators of Compromise (IoC) tough.”

To counter such threats, it can be suggested to block sites that use the WebAPK system to have out phishing attacks.
The progress arrives as Resecurity discovered that cybercriminals are more and more leveraging specialised unit spoofing resources for Android that are marketed on the dark web in a bid to impersonate compromised account holders and bypass anti-fraud controls.
The antidetect applications, which includes Enclave Services and MacFly, are capable of spoofing cellular system fingerprints and other software and network parameters that are analyzed by anti-fraud devices, with threat actors also leveraging weak fraud controls to conduct unauthorized transactions by using smartphones using banking malware these as TimpDoor and Clientor.
“Cybercriminals use these applications to access compromised accounts and impersonate genuine consumers by exploiting stolen cookie documents, impersonating hyper-granular unit identifiers, and utilizing fraud victims’ special network settings,” the cybersecurity firm explained.
