Overview

HawkEye Keylogger (also tracked as HawkEye, HawkEye Reborn, and Spyware.HawkEye) is a commercial .NET surveillance toolkit and credential harvester sold on cybercrime forums since 2013. Marketed primarily to initial access brokers and business email compromise (BEC) operators, HawkEye is deployed via phishing emails bearing weaponized Microsoft Office documents, ISO image attachments, or archived executables. Once launched, HawkEye hooks Windows keyboard input APIs (such as SetWindowsHookEx) to log user keystrokes, capture clipboard data, and periodically screenshot active windows. It includes built-in extraction routines that harvest credentials from over 40 popular web browsers (Chrome, Edge, Firefox, Opera), email applications (Outlook, Thunderbird, Windows Live Mail), FTP clients (FileZilla, WinSCP), and gaming platforms. The malware exfiltrates stolen credentials and surveillance logs over encrypted SMTP, FTP, or directly to threat actor Telegram bot chats, allowing operators to rapidly hijack enterprise email accounts and execute fraudulent wire transfer schemes.

Command & Control (C2) and Network Profile

How this family talks to its operators. C2 traffic can often identify a family even when its code and configuration are hard to analyse. Ports and patterns are historical and change between campaigns, so use them as hunting leads rather than block-only rules.

Indicators of Compromise

Public indicators drawn from CISA advisories and vendor reporting. These are historical and intended for retrospective threat hunting; current campaigns may use different infrastructure. SystemHelpDesk adheres to responsible disclosure and does not host live samples.

File hashes (SHA-256, sample)

Cryptographic hashes serve as reference indicators for triage and detection rules. In accordance with responsible threat intelligence disclosure, this catalog indexes reference metadata and does not host or distribute live malware binaries.

Tiered Detection Rules (Cisco CAIRN Model)

Modern threat detection requires multi-layered rule engineering. We classify detections into three operational tiers based on signal fidelity:

Tier 1 Primitive Artifact Rule (Fast Triage)

Matches raw strings and file markers. Vulnerable to binary repacking and simple obfuscation.

rule MALWARE_WIN_HAWKEYEKEYLOGGER_T1_ARTIFACT {
    meta:
        description = "Tier 1 Primitive Artifact: Raw string matches for Hawkeyekeylogger"
        tier = "T1 - Primitive Artifact"
        confidence = "Low-Medium (Fast Triage)"
        author = "SystemHelpdesk Threat Research Desk"
        date = "2026-10-14"
    strings:
        $s1 = "hawkeyekeylogger" ascii wide nocase
        $s2 = "hawkeye keylogger" ascii wide nocase
        $s3 = "hawkeye reborn" ascii wide nocase
        $s4 = "trojan.hawkeye" ascii wide nocase
        $s5 = "spyware.hawkeye" ascii wide nocase
        $s6 = "win32/hawkeye" ascii wide nocase
    condition:
        uint16(0) == 0x5a4d and any of them
}

Tier 2 Behavioral Context Rule (Process Chains & Sigma)

Tracks parent-child process anomalies and suspicious scripting telemetry. Resilient against file renames.

Containment & Response Steps

Home Users: If you suspect a malware infection on your personal device, disconnect from the internet immediately and run a full system scan with your antivirus software (see our TotalAV Antivirus & Security Support Guide). The steps below are intended for IT professionals responding to enterprise incidents.

Ordered checklist for responders. Adapt to your environment and engage professional support for active incidents.

  1. Terminate active .NET payloads and inspect processes hooking low-level keyboard messages via SetWindowsHookEx.
  2. Remove persistence keys under HKCU\Software\Microsoft\Windows\CurrentVersion\Run.
  3. Block outbound SMTP ports (25, 465, 587) and FTP port 21 from general workstation subnets at the perimeter firewall.
  4. Immediately rotate corporate email account passwords and invalidate session tokens to thwart BEC fraud.

What to Avoid

Common mistakes during response to this family that can destroy evidence, spread the infection, or worsen recovery.

  1. Do not allow workstations direct outbound email transmission capabilities without traversing authenticated corporate mail relays.
  2. Avoid opening unverified ISO, VHD, or compressed archive files attached to unsolicited vendor invoices.
  3. Never store unencrypted administrative credentials inside web browsers or FTP clients.

Frequently Asked Questions

What is HawkEye Keylogger?

HawkEye is a commercial .NET keylogger and information stealer that records keystrokes, screenshots, and stored browser/email passwords to execute Business Email Compromise (BEC) attacks.

How is HawkEye Keylogger delivered to victims?

HawkEye is distributed primarily through phishing emails disguised as invoices, shipping documents, or purchase orders containing malicious Office attachments or ISO files.

How does HawkEye send stolen data to attackers?

HawkEye exfiltrates harvested keystrokes and credentials using hardcoded SMTP credentials to send email reports, FTP file uploads, or through Telegram Bot API HTTP requests.

What applications does HawkEye target for passwords?

HawkEye targets saved passwords in Google Chrome, Microsoft Edge, Mozilla Firefox, Microsoft Outlook, Mozilla Thunderbird, FileZilla, and multiple instant messengers.

How can organizations protect against HawkEye Keylogger?

Protect against HawkEye by enforcing email gateway scanning for suspicious ISO/ZIP attachments, blocking outbound SMTP/FTP from user workstations, and deploying endpoint detection for API hooking.

How do I remove the Hawkeyekeylogger Infostealer from Windows?

Manual removal of Hawkeyekeylogger is highly discouraged as it may leave persistence mechanisms intact. We recommend disconnecting the device from the internet and utilizing a professional incident response service or enterprise-grade EDR software to conduct a full forensic sweep.

Is Hawkeyekeylogger a virus or a Infostealer?

Hawkeyekeylogger is classified as a Infostealer. Unlike traditional viruses that infect files, modern malware like Hawkeyekeylogger typically operates as a standalone payload designed to compromise systems, steal data, or deploy secondary stage implants.

What are the main symptoms of a Hawkeyekeylogger infection?

Symptoms of Hawkeyekeylogger can include unexpected system slowness, unauthorized outbound network traffic to unknown IP addresses, disabled security software, and suspicious background processes running from AppData or Temp directories.
