SparkCat is a newly discovered malware that hides in images to steal cryptocurrency recovery phrases and other sensitive data. Cybersecurity firm Kaspersky has revealed how this new threat operates and how to protect yourself.
Kaspersky researchers have discovered a new attack vector that is distinguished by its ability to analyze images in search of sensitive information, particularly recovery phrases or seed phrases of cryptocurrency wallets.
In an ecosystem where personal security is paramount, SparkCat poses a direct threat to users’ digital assets.
PREPARE YOUR WALLETThis new malware, which spreads stealthily, exploits the growing tendency of users to store Screenshots or photos of your recovery phrases on your devices or in the cloudSparkCat scans these files for patterns and recognizable text associated with wallet keys and other critical information. Once this information is identified, the malware extracts it and sends it to the attackers, who can then empty the victims’ cryptocurrency wallets.
The sophistication of SparkCat, according to the report presented by Kaspersky, lies in its ability to operate discreetly, avoiding detection by traditional antivirus software until very recently. In this article, we will delve into how SparkCat works, how it spreads, and Kaspersky’s recommendations to mitigate the risk this new malware poses to cryptoasset owners.
SparkCat exposed: Kaspersky analysis
Kaspersky, a leading cybersecurity company, has detailed the workings of SparkCat following extensive forensic analysis.
The firm explains that this malware is not limited to merely searching for text in images. Rather, it is a sophisticated malicious software that uses advanced optical character recognition (OCR) techniques to identify text even in low-quality or distorted images. This means that SparkCat can extract information from blurry screenshots, photos taken in low-light conditions, or images that have been compressed or edited.
This adaptability of SparkCat makes it a particularly dangerous tool in the hands of cybercriminals. In addition to cryptocurrency wallet recovery phrases, SparkCat also hunts for other types of sensitive information, such as private keys, passwords, and account details for cryptocurrency and other platforms.
Researchers warn that if cybercriminals gain access to this information, they can then use it to access a wide range of online accounts and services, amplifying the potential harm to victims.
“The main goal of hackers is to find recovery phrases for cryptocurrency wallets. With this information, they can gain full control over the victim’s wallet and steal funds.”, Kaspersky said.
Kaspersky research underlines the importance of Keep security software up to date and be extremely cautious when storing sensitive information in digital format.

How does SparkCat spread?: Infection vectors
SparkCat is distinguished by its stealth and the variety of methods it employs to infiltrate its victims’ devices. Unlike other types of malware that rely on a single attack vector, SparkCat uses a combination of tactics to maximize its reach and avoid detection.
One of its most worrying characteristics is its presence on official platforms such as the AppStore and Google Play since at least March 2024, which gives it an appearance of legitimacy and makes it difficult for users to identify. Because of this, Kaspersky highlighted that the malware It spreads both through infected legitimate applications and through lures. carefully designed to fool users. These lures include couriers, AI assistants, food delivery apps and, particularly, cryptocurrency-related applications.
This last category is especially relevant, as users looking for tools to manage their digital assets may be more susceptible to downloading malicious apps that promise to make this task easier. In addition to official app stores, SparkCat It is also distributed through unofficial sources, which further increases its reach.
INVITE AND WINKaspersky telemetry data indicates that infected versions are spreading through alternative channels, suggesting an active and diversified distribution campaign. On Google Play, Infected apps have been downloaded more than 242.000 times, demonstrating the magnitude of the problem and the need for users to take extra precautions when downloading apps, especially those related to cryptocurrencies and digital assets.
The hidden danger in your images
As we have seen up to this point, SparkCat represents a particularly stealthy threat due to its ability to operate covertly and extract sensitive information from images.
Unlike many types of malware that focus on stealing passwords or intercepting transactions, SparkCat more specifically targets cryptocurrency wallet recovery phrases, which are the key to accessing funds. If an attacker obtains a wallet’s recovery phrase, they can empty it without needing to know the password or have access to the user’s device.
How to mitigate risk?
To mitigate the risk of falling victim to SparkCat and other types of malware targeting cryptocurrency users, Kaspersky offers a number of practical recommendations, including: Never store recovery phrases in digital format, avoiding taking screenshots or photographs of this information and never saving it to the cloud.
In addition, it is recommended that Using strong and unique passwords that combine upper and lower case letters, numbers and symbols. It is important to never use the same password for different accounts, and to change them regularly. It is also important to activate two-factor authentication (2FA), as it adds an extra layer of security to accounts, requiring a verification code in addition to the password to log in.
