How it works

  1. 1Execution and evasion

    Dark Radar observation

    The payload ran from the Program Files folder (latest 200 logs, 31.5%).

    Ran from the install.exe file in the Windows folder (latest 200 logs, 20%).

    Breaking point: Unsigned files running from user folders and injections into .NET tools are stopped by application control and EDR.

  2. 2Discovery

    Dark Radar observation

    Infected systems: Windows 10 60%.

    T1082System Information Discovery

    Breaking point: Bulk system and security software queries from a short-lived process trigger an EDR alert.

  3. 3Data collection

    Dark Radar observation

    Data found in the latest 200 logs: password file 82%, cookies 99%, autofill 93.5%, cards 8.5%, wallets 6%.

    T1555.003Credentials from Web BrowsersT1539Steal Web Session Cookie

    Breaking point: A process other than the browser reading browser profile files is blocked or triggers an alert.

Risk and impact

  • When gaming and community accounts (Steam, Discord) are taken over, they are reused for fraud and malware distribution.
  • Stolen session cookies are enough to take over cloud, email and SaaS sessions without a password or multi-factor authentication prompt.
  • Corporate passwords saved on personal devices also leak through infections outside the corporate network; these logs are sold to initial access brokers.
  • Log archives are reshared for years; as long as the password is not changed, the same credential can be used again and again.
  • Compromised email, messaging and social media accounts become the next link in phishing and malware distribution.
10

Defense

  • When an infection is detected, revoke not only the password but all related sessions and access tokens.
  • Turn off password saving in the browser through corporate policy; use a corporate password manager.
  • Move to phishing-resistant multi-factor authentication (FIDO2/passkey); bind sessions to the device.
  • Block setup files downloaded from unlicensed software, game cheats and sponsored search results.
  • Monitor flows where the user runs a command by pasting it into the Run dialog or terminal (ClickFix) with endpoint rules.
  • Continuously monitor your corporate domains and employee email addresses in stealer logs with Dark Radar.

Learning center

How does this malware spread?
  • The payload ran from the Program Files folder (latest 200 logs, 31.5%).
  • Infostealer families mostly spread through unlicensed software, fake updates, sponsored search ads and phishing emails.
How can its presence on a system be detected?
  • Sign-ins to accounts from an unrecognized country or device.
  • A new infostealer log in Dark Radar for your corporate domain or an employee email address.
Which Windows artifacts should be examined?
  • Prefetch (C:\Windows\Prefetch) — shows that a short-lived payload ran.
  • Amcache.hve and ShimCache — path and hash of the executed file.
  • Downloads folder and Zone.Identifier stream — the address the file was downloaded from.
  • Browser history — the fake download page or fake CAPTCHA address.
  • RunMRU registry key — commands pasted into the Run dialog.
  • Randomly named folders and DLLs under %TEMP% and %LOCALAPPDATA%.
Which log records matter?
  • Sysmon Event 1 / Security 4688Process creation: unsigned processes starting from Temp and Downloads folders, mshta, powershell -enc chains.
  • Sysmon Olay 11 / 23File creation and deletion: self-deleting payloads, DLLs dropped under Temp.
  • Sysmon Olay 3 / 22Network connection and DNS query: to newly registered domains, C2 resolution via Telegram, Steam or Pastebin.
  • Object access auditing (4663)A process other than the browser reading Login Data, Cookies and Local State files.
  • PowerShell 4104Script block logging: obfuscated downloader commands.
  • Identity provider sign-in logsSessions after the infection from a different country and device, without a multi-factor authentication prompt.
Which MITRE techniques is it associated with?

How should a SOC analyst respond?
  1. Isolate the device from the network; do not reinstall it before taking memory and disk images.
  2. Determine the infection date; list all accounts that were signed in on the device after that date.
  3. Change the passwords of these accounts, revoke their sessions and access tokens, and re-enroll multi-factor authentication devices.
  4. Search identity provider and SaaS logs for new country, device and token usage after the infection.
  5. If a recovery phrase or wallet file was exposed, move the assets to a new wallet.
  6. Find the initial access path (email, ad, unlicensed software, fake CAPTCHA) and check other users who used the same path.
  7. Reinstall the device from a clean image.
