What it is
Information-stealing malware for Windows, sold to criminals as a service.
What it does
Steals saved browser passwords, cookies, card details and cryptocurrency wallet data, then sends it to a server the criminals control.
Who uses it
Sold to affiliates who run their own campaigns. The US Department of Justice, in October 2024 and March 2026, charged two people it alleges developed and administered it. These are allegations, not findings of guilt.
How it gets in
Fake software downloads, phishing emails, malicious adverts and sideloading, as described by the US Department of Justice.
What to do first
Turn on multi-factor authentication with hardware keys where possible, and do not let staff save passwords in browsers, as MITRE suggests.

What it does

RedLine was sold to other criminals, who ran their own campaigns with it. The US Department of Justice says affiliates bought a license and then infected their own targets. The stolen data is called “logs” and is sold on cybercrime forums.

The Department of Justice also says RedLine has been used in intrusions against major corporations. Stolen cookies and other system data can let criminals get round multi-factor authentication.

What it can do

What MITRE ATT&CK lists this malware as doing, by tactic. Each id opens our technique page where one exists, otherwise MITRE.

Credential Access

  • Credentials from Password Stores: Credentials from Web Browsers T1555.003

    It was designed to take saved logins, card details and autocomplete data from web browsers.[1]

  • Steal Web Session Cookie T1539

    It steals browser cookies and settings. The Department of Justice says this can help criminals get past multi-factor authentication.[1, 2]

    It has taken logins from VPN services, FTP clients and chat clients.[1]

Collection

  • Data from Local System T1005

    It collects locally stored data, including chat logs and files from services such as Steam, Discord and Telegram.[1]

  • Screen Capture T1113

    It can take screenshots of the infected computer.[1]

Impact

  • Financial Theft T1657

    It collects data from cryptocurrency wallets and credit card details from browsers.[1]

Exfiltration

  • Exfiltration Over C2 Channel T1041

    It sends victim data to its command server, which MITRE also calls the RedLine panel server.[1]

Command and Control

  • Application Layer Protocol: Web Protocols T1071.001

    It has talked to its command servers over HTTP and HTTPS.[1]

  • Ingress Tool Transfer T1105

    It can download more payloads onto the infected computer.[1]

  • Web Service T1102

    It has used legitimate file sharing services to host malicious payloads.[1]

Execution

  • User Execution: Malicious File T1204.002

    It has built in settings that stop it running on hosts in chosen countries.[1]

  • Obfuscated Files or Information: Software Packing T1027.002

    It has been packed with obfuscation tools to hide its code.[1]

Defense Impairment

    It can switch off security software and update services.[1]

Discovery

  • Software Discovery: Security Software Discovery T1518.001

    It has looked for installed antivirus software.[1]

How it spreads

RedLine does not spread by itself. The US Department of Justice says affiliates spread it with malicious adverts, phishing emails, fake software downloads and malicious software sideloading, and that lures such as COVID-19 and Windows update themes were used. MITRE adds that it has been disguised as legitimate software such as a "PDF Converter Software" and pushed through poisoned search results. In September 2022, Security Boulevard reported a campaign that used hacked Facebook business pages: sponsored posts offered free Adobe Acrobat Reader, the link preview showed Mediafire instead of Adobe, and victims had to download the file, extract it and run it.

Detection and defense

  1. Protect logins with hardware keys

    MITRE suggests hardware-based tokens such as FIDO keys, which tie a login to the real site, so stolen cookies are harder to use. The Department of Justice warns that stolen cookies can help bypass multi-factor authentication.[5, 2]

    Counters: T1539

  2. Watch sign-in activity

    Audit logins and look for impossible travel or odd behavior that could show a stolen session cookie in use.[5]

    Counters: T1539

  3. Limit passwords saved in browsers

    MITRE says organizations may weigh the risk of storing credentials in browsers, and use policy, technical controls and training to prevent it.[6]

    Counters: T1555.003 T1555

  4. Keep browsers and password managers updated

    MITRE advises regular updates to browsers, password managers and related software.[5, 6]

    Counters: T1555.003 T1539

  5. Train users on fake downloads and phishing

    The Department of Justice says RedLine spreads through fake software downloads, phishing and malicious adverts. MITRE advises training users to spot phishing.[2, 5, 1]

    Counters: T1204.002 T1539

  6. Use official detection and victim resources

    MITRE lists detection strategies for browser credential store access (DET0037) and web session cookie theft (DET0509). The Department of Justice points to the Operation Magnus website, www.operation-magnus.com, for the public and potential victims.[6, 5, 2]
