Kaspersky Labs has identified a sophisticated malware campaign targeting cryptocurrency users through malicious software development kits embedded in mobile apps available on Google Play and the Apple App Store. Named "SparkCat," this malware utilizes optical character recognition to scan users' photos for cryptocurrency wallet recovery phrases, which hackers then use to access and deplete affected wallets.

In a comprehensive report dated February 4, 2025, Kaspersky researchers Sergey Puzan and Dmitry Kalinin detailed how the SparkCat malware infiltrates devices and searches images for recovery phrases through multilingual keyword detection. Once these phrases are obtained, attackers gain unfettered access to victims' crypto wallets. The hackers thus achieve full control over the funds, as highlighted by the researchers.

Moreover, the malware is designed to steal additional sensitive information, such as passwords and private messages captured in screenshots. Specifically on Android devices, SparkCat masquerades as a Java-based analytics module called Spark. The malware receives operational updates from an encrypted configuration file on GitLab and uses Google's ML Kit OCR to extract text from images on infected devices. Detection of a recovery phrase results in the malware sending the information back to attackers, allowing them to import the victim's crypto wallet onto their devices.

Kaspersky estimates that since its emergence in March 2023, SparkCat has been downloaded around 242,000 times, predominantly impacting users in Europe and Asia.

In a separate but related report from mid-2024, Kaspersky has been monitoring another Android malware campaign involving deceptive APKs like Tria Stealer, which intercepts SMS messages and call logs, and steals Gmail data.

The presence of this malware spans numerous apps, some seemingly legitimate like food delivery services, and others designed to attract unwary users, such as AI-enabled messaging apps. Common features among these infected apps include the use of the Rust programming language, cross-platform capabilities, and sophisticated obfuscation methods to evade detection.

The origins of SparkCat remain unclear. The researchers have not ascribed the malware to any known hacking group but have noted Chinese-language comments and error messages within the code, suggesting fluency in Chinese by the developer. While it shares similarities with a campaign uncovered by ESET in March 2023, its precise source remains unidentified.

Kaspersky strongly advises users against storing sensitive information like crypto wallet recovery phrases in their photo galleries. Instead, they recommend employing password managers and regularly scanning for and eliminating suspicious applications.

The findings were originally reported on 99Bitcoins in the article titled "Malicious SDKs on Google Play and App Store Steal Crypto Seed Phrases: Kaspersky."

Infostealers have emerged as one of the most insidious and rapidly growing cyber threats today. These stealthy malware programs are specifically designed to infiltrate your device and silently extract sensitive information such as passwords, cookies, browser data, and even wallet credentials without your knowledge or consent.
 While infostealers were once primarily focused on targeting large organizations and enterprises, recent trends show a sharp increase in attacks against individual users, particularly those involved in the cryptocurrency ecosystem. This development raises significant concerns as stolen credentials are rapidly traded on dark web platforms or directly utilised by attackers to compromise accounts and drain cryptocurrency holdings.
🛠️ How Infostealers Infiltrate Devices:
The techniques employed by infostealers to compromise devices are diverse and continually evolving in sophistication. Common vectors of infection include phishing emails designed to deceive users into clicking malicious links, counterfeit software installers that conceal malware within seemingly legitimate applications, misleading online advertisements, Trojan-infected files, and browser extensions that appear benign but harbor concealed malicious payloads. Once deployed, infostealers operate stealthily, systematically scanning the system for stored login credentials, cookies, and other sensitive information. This data is then transmitted directly to the attackers, often without producing any immediate symptoms or alerts, thereby rendering detection exceedingly challenging.
🚩 Early Signs of Infection   
Though infostealers are built for stealth, a few red flags might give them away:  
Unexpected browser notifications or suspicious extensions that were not intentionally installedLogin alerts from unfamiliar or unauthorized locationsSudden changes to your password or security settings
🧰 What You Can Do to Protect Yourself  
To defend against infostealers: 
Exercise caution when downloading files or software from sources other than official or verified platformsRefrain from clicking on suspicious links or opening attachments from unknown or untrusted senders.Ensure that your software and operating system updated regularlyUse reputable antivirus/anti-malware programs to perform routine scans for potential threats.
  📢 Stay Ahead of the Threat 
The rise of infostealers is a clear reminder, cybersecurity hygiene is no longer optional. For crypto users, the risks are particularly significant, as login credentials frequently represent the sole barrier protecting assets from complete compromise.
📍Stay alert. Review your digital habits regularly. And never stop learning about the threats out there.

Malware, short for malicious software, refers to any software that is designed to harm or exploit a system or its user.
Here are some common types of malware:
1. Viruses: Replicate and spread to other files or systems.
2. Worms: Self-replicating malware that spreads without user interaction.
3. Trojans: Disguise themselves as legitimate software to gain access.
4. Spyware: Secretly monitor and collect user data.
5. Adware: Display unwanted advertisements.
6. Ransomware: Demand payment in exchange for restoring access to data.
7. Rootkits: Hide malware or unauthorized access from the user.
8. Keyloggers: Record keystrokes to steal sensitive information.
9. Botnets: Networks of infected devices controlled remotely.
10. Exploits: Take advantage of software vulnerabilities to gain access.
To protect yourself from malware:
1. Use antivirus software.
2. Keep software up-to-date.
3. Avoid suspicious downloads.
4. Use strong passwords.
5. Enable firewall protection.
6. Use secure networks.
7. Regularly back up data.
8. Use a reputable VPN.
9. Be cautious with email attachments.
10. Use a secure search engine.
Remember, prevention and vigilance are key to protecting yourself from malware.

The recent revelation by Scam Sniffer about a fake "Homebrew" malware, distributed through ads on Google, has raised alarms in the cryptocurrency world. This attack, designed to steal wallet data and digital assets, not only endangers individual investors but also undermines overall trust in advertising platforms and the security of the crypto ecosystem. Cybercriminals are exploiting common tools, such as Google Ads, to target unsuspecting users, demonstrating how even the most trusted channels can be used for malicious purposes.
