A new type of malware called SparkKitty is using optical character recognition (OCR) to steal cryptocurrency wallet seed phrases directly from photos and screenshots in a device's gallery, bypassing traditional keylogging defenses. Once installed from malicious apps posing as legitimate crypto services on the Apple App Store and Google Play, it requests photo access, scans images for confidential data like passwords and seeds, and sends it to hackers' servers. Control of a seed phrase gives attackers complete access to drain the wallet. Initially detected as SparkCat, the evolved SparkKitty was found in the iOS app 币coin (hiding in obfuscated code) and the Android app SOEX (downloaded over 10,000 times). This method allows theft even when sensitive data is never typed or copied. The report comes alongside news of other attacks, like a method to hijack Telegram Desktop sessions bypassing 2FA.

After installation, the infected program requests access to photos, scans images for confidential information, and sends the results to remote servers controlled by attackers. SparkKitty does not use traditional data interception methods, such as keylogging or clipboard tracking, but rather optical character recognition (OCR) technology to extract text directly from photos and screenshots. This allows it to bypass standard security systems and steal passwords, seed phrases, and other secret data, even if they are not entered via the keyboard or copied to the clipboard, explained Check Point analysts.

If attackers obtain a seed phrase, they gain full control of the crypto wallet and can empty it in a matter of minutes. The malicious program operates covertly in the background, so the device owner may not immediately notice the theft of funds—until they log into their crypto wallet.

The malicious program was first discovered by Kaspersky experts in early 2024 under the name SparkCat. But now the program has changed. The creators of SparkKitty have started distributing it more frequently in the Apple App Store and Google Play under the guise of applications mimicking legitimate cryptocurrency services, messengers, and entertainment services. This has significantly increased the likelihood of installation by unsuspecting users.

For iOS devices, the malicious program was embedded in the cryptocurrency app "币coin" and uploaded to the App Store. It remains unclear whether the developer account was hacked or if the developer is aware of the infection. The app managed to bypass Apple's security review by hiding malicious code within obfuscated frameworks AFNetworking and libswiftDarwin.dylib. These modules were crafted so that the app appeared legitimate, allowing SparkKitty to evade detection, explained Check Point specialists.

The Android version was distributed through the SOEX app, which was downloaded over 10,000 times from Google Play. The app posed as a messaging and cryptocurrency platform but allowed hackers to access multimedia storage on smartphones and other devices, track file changes, and steal data.

Recently, experts from SlowMist discovered a new method hackers use to intercept Telegram Desktop sessions, bypass two-factor authentication (2FA), and steal crypto wallet data. Recently, the CEO of the financial platform Robinhood, Vlad Tenev, was targeted—his X (formerly Twitter) account was hacked to promote the meme coin VLAD.

QWhat is the name of the new malware that steals seed phrases from cryptocurrency wallets using OCR technology?

ASparkKitty

QWhat is the primary technique used by the SparkKitty malware to steal sensitive information, and why is it effective?

AIt uses Optical Character Recognition (OCR) to extract text directly from photos and screenshots. This is effective because it bypasses standard security systems by stealing data that is not typed on a keyboard or copied to the clipboard.

QWhich major app stores are mentioned as distribution channels for the disguised SparkKitty malware?

AApple App Store and Google Play

QWhat was the method used by the iOS version of SparkKitty to hide its malicious code and evade Apple's security checks?

AIt hid the malicious code in obfuscated frameworks, specifically AFNetworking and libswiftDarwin.dylib.

QWhat other recent attack vector, unrelated to SparkKitty, is mentioned where hackers bypassed Telegram Desktop's two-factor authentication?

AExperts from SlowMist discovered a new method hackers use to hijack Telegram Desktop sessions, bypassing two-factor authentication (2FA) to steal cryptocurrency wallet data.

Thanks to Dice Rolls, Bitcoin Keys Are Stored Offline, But Not Everyone Will Do It

The article discusses using dice rolls to generate secure Bitcoin wallet seeds, providing entropy independent of potentially flawed hardware random number generators. It explains that each fair dice roll offers about 2.585 bits of entropy, with around 50 rolls needed for a standard 12-word seed phrase and 99+ recommended for higher security. This method gained attention after a vulnerability was revealed in some Coldcard hardware wallets, where a faulty firmware RNG (dating back to 2021) compromised generated keys. The analysis notes that while a dice-generated main seed was safe from this specific flaw, other Coldcard functions (like creating paper wallets, backup keys, or passwords) could still be vulnerable if they used the defective RNG. The piece argues that while dice-based entropy is technically robust, the manual process is error-prone, tedious, and unrealistic for most new users, who might make mistakes in recording or inputting rolls. It concludes that while manual entropy generation should remain an option for advanced users, the long-term goal is to develop reliable, user-friendly hardware and software that securely generates randomness without requiring specialized knowledge. Coldcard users are advised to check their firmware version and replace any secondary secrets (like paper wallet keys) created with vulnerable devices, while also considering multi-signature setups with devices from different manufacturers for added security.
