Mint Stealer is information-stealing malware sold as a service (Malware-as-a-Service, or MaaS). It steals browser data, cryptocurrency wallet details and other sensitive data from infected systems, uploads it to free file-sharing sites and talks to command-and-control (C2) servers. This report covers how it works, how it avoids detection and the indicators of compromise (IoCs).
Operating under the Malware-as-a-Service (MaaS) model, Mint Stealer effectively steals a wide range of sensitive data from compromised systems, including web browser information, cryptocurrency wallet details, and more. Mint Stealer evades detection through techniques such as encryption, obfuscation, and file compression. The malware’s operational model, which involves uploading data to free file-sharing sites and communicating with command-and-control (C2) servers, highlights its adaptability to different users.

Why Does a Stealer Sold as a Service Matter?
Under the Malware-as-a-Service model, the author sells or rents the malware and many different buyers run their own campaigns. That is why one family such as Mint Stealer can show up in very different attacks, and why defenders track behavior and indicators rather than a single operator. For the wider picture of this malware type, see our entries on infostealers and stealer logs.
How Does Stolen Browser Data Lead to Account Takeover?
MITRE ATT&CK groups password theft under Credentials from Password Stores (T1555), which includes credentials from web browsers. It also describes stealing web session cookies (T1539): a valid cookie gives access without a password, and session cookies can bypass some multi-factor authentication. Well known stealers such as RedLine and Lumma are listed there as doing this. Our entry on session cookies explains why they are so valuable.
How Can Teams Defend Against Stealers Like Mint?
MITRE ATT&CK suggests hardware-based tokens such as FIDO keys that check the login domain, regular deletion of persistent cookies, training people to spot phishing domains, and keeping browsers and security software current. For detection, watch for unusual access to browser cookie storage and for a session token used from an unexpected place or device. When a sample is found, record its indicators of compromise and search for them across the estate.
