Designed to hijack accounts, steal cryptocurrency, and install crypto miners, Stealka has quickly become a significant threat for both casual users and investors.
By masquerading as popular game cracks, cheats, and mods, the malware lures victims into downloading it voluntarily, often without realizing the risk.
How Stealka Spreads
Stealka spreads through legitimate-looking platforms such as GitHub, SourceForge, Softpedia, and sites.google.com. Users are enticed by downloads claiming to be cracked versions of games or software, sometimes as outrageous as a fake Half-Life 3 release. The attackers even create convincing websites with fake antivirus banners to simulate security checks. Once the file is run, the malware activates and begins collecting data, from browser credentials to crypto wallet information.

A real-world example illustrates the danger: a compromised account posted a GTA V mod on a gaming site, which included Stealka. Users downloading the mod unknowingly exposed their browsers, wallets, and local files to the stealer. This demonstrates how attackers leverage social trust and popular search terms to increase infection rates.
What Makes Stealka Dangerous
Stealka’s primary target is browsers built on Chromium and Gecko engines, including Chrome, Firefox, Opera, Edge, Brave, and many others. The malware extracts sensitive autofill data such as passwords, addresses, and payment cards. Cookies and session tokens are particularly valuable, as they can bypass two-factor authentication and allow attackers to hijack accounts seamlessly.

Beyond browsers, Stealka targets 115 browser extensions for crypto wallets, password managers, and 2FA apps. Popular wallets at risk include Binance, Coinbase, MetaMask, Trust Wallet, and Phantom. Password managers like 1Password and Bitwarden, along with email clients, messaging apps, note-taking apps, and even VPN clients, are vulnerable. The malware also collects general system information, installed programs, and screenshots, giving attackers a comprehensive view of the victim’s digital environment.
How to Protect Yourself from Stealka
Kaspersky recommends installing reliable antivirus software to detect and block malware in real time. Avoid storing sensitive information in browsers and instead use encrypted password managers. Pay for legitimate software and game mods rather than relying on pirated versions. Enabling two-factor authentication with backup codes stored securely adds an additional layer of defense. Awareness and cautious behavior remain the most effective strategies against Stealka and similar threats.
