A brand new pressure of cell spyware and adware, dubbed SparkKitty, has infiltrated Apple’s App Retailer and Google Play, posing as crypto-themed and modded apps to stealthily extract pictures of seed phrases and pockets credentials.
The malware seems to be a successor to SparkCat, a marketing campaign first uncovered in early 2025, which used pretend assist chat modules to silently entry person galleries and exfiltrate delicate screenshots.
SparkKitty takes the identical technique a number of steps additional, Kaspersky researchers mentioned in a Monday put up.
In contrast to SparkCat, which largely spreads by way of unofficial Android packages, SparkKitty has been confirmed inside a number of iOS and Android apps out there by way of official shops, together with a messaging app with crypto alternate options (with over 10,000 installs on Google Play) and an iOS app referred to as “币coin,” disguised as a portfolio tracker.
On the core of the iOS variant is a weaponized model of the AFNetworking or Alamofire framework, the place attackers embedded a customized class that auto-runs on app launch utilizing Goal-C’s +load selector.
On startup, it checks a hidden configuration worth, fetches a command-and-control (C2) tackle, and scans the person’s gallery and begins importing pictures. A C2 tackle instructs the malware on what to do, reminiscent of when to steal information or ship information, and receives the stolen info again.
The Android variant makes use of modified Java libraries to attain the identical objective. OCR is utilized by way of Google ML Equipment to parse pictures. If a seed phrase or personal key’s detected, the file is flagged and despatched to the attacker’s servers.
Set up on iOS is finished by way of enterprise provisioning profiles, or a technique meant for inner enterprise apps however typically exploited for malware.
Victims are tricked into manually trusting a developer certificates linked to “SINOPEC SABIC Tianjin Petrochemical Co. Ltd.,” giving SparkKitty system-level permissions.
A number of C2 addresses used AES-256 encrypted configuration information hosted on obfuscated servers.
As soon as decrypted, they level to payload fetchers and endpoints, reminiscent of/api/putImages and /api/getImageStatus, the place the app determines whether or not to add or delay photograph transmissions.
Kaspersky researchers found different variations of the malware using a spoofed OpenSSL library (libcrypto.dylib) with obfuscated initialization logic, indicating an evolving toolset and a number of distribution vectors.
Whereas most apps look like focused at customers in China and Southeast Asia, nothing in regards to the malware limits its regional scope.
Apple and Google have taken down the apps in query following disclosure, however the marketing campaign has doubtless been energetic since early 2024 and should still be ongoing by way of facet loaded variants and clone shops, researchers warned.
