In the context of Infostealers, a Wallet refers to the digital files, browser extensions, or applications used to store cryptocurrency. Infostealers are specifically programmed to locate and exfiltrate private keys, seed phrases, and wallet database files (e.g., wallet.dat), allowing attackers to drain digital assets instantly.
For modern cybercriminals, stealing a Wallet is the fastest path to a payday. Because cryptocurrency transactions are irreversible and pseudonymous, they provide the perfect "loot" for an Infostealer. Unlike a credit card that can be canceled, a compromised crypto wallet usually results in a total and permanent loss of funds.
Infostealers utilize specialized "grabbers" to find and steal wallet-related data from several locations:
wallet.dat (Bitcoin), default_wallet (Monero), or specific folders for apps like Exodus and Atomic Wallet..txt, .docx, or .pdf files containing keywords like "mnemonic," "private," or "seed" to find plain-text backups of recovery phrases.Modern infostealer logs are often integrated with "Crypto Drainers." Once the Wallet data is exfiltrated to a C2 panel, an automated script can interact with the blockchain to sweep all tokens, NFTs, and staked assets to the attacker's address within seconds.
From a security standpoint, the presence of cryptocurrency wallets on corporate devices is a significant risk. Dark Radarmonitors the Dark Web for leaked logs that contain wallet signatures associated with your organization’s domain. Identifying these leaks early is vital for incident response, as it confirms that the infected device has been deeply compromised and sensitive file stores have been accessed.
In summary; A digital Wallet is the "gold standard" of data theft. To prevent loss, users should avoid storing seed phrases on internet-connected devices and utilize hardware wallets that keep private keys offline and out of reach for any infostealer.
A Worm is a type of standalone malware that replicates itself in order to spread to other computers. Unlike traditional viruses, it does not need to attach itself to an existing program or require human intervention to spread. When integrated with Infostealer functionality, a worm can rapidly compromise an entire enterprise network to harvest credentials from every connected device.
Web Skimming (also known as Magecart attacks) involves injecting malicious JavaScript code into a website’s checkout page to steal payment card information and personal data in real-time. Unlike an Infostealer that resides on a user's device, web skimming captures data directly from the browser during a web transaction.
