How to remove HackBoss stealer malware from the operating system?

What kind of malware is the HackBoss stealer?

HackBoss is a piece of malicious software classified as a stealer. It operates by redirecting outgoing cryptocurrency transactions by replacing recipients' cryptowallet addresses with its own. This malware has netted significant gain in Bitcoin, Ethereum, Monero, Litecoin, and Dogecoin cryptocurrencies.

The HackBoss stealer is active worldwide, particularly in the United States, Nigeria, and Russia. Its main proliferation method is via various fake hacking, "cracking", password brute-forcing tools, and other malicious applications - supposedly designed to target cryptocurrency-related, banking, social networking/media, and dating accounts.

The fake apps themselves are primarily distributed through the Hack Boss Telegram channel; however, they have been observed being spread through a variety of blogs, forums, and YouTube channels.

HackBoss stealer overview

The scam apps are downloaded in archives (usually in the ZIP format), which when unpacked - contain an executable file. Upon this file's execution, an interface of the fake application is opened.

These apps have been noted wearing dozens of different disguises, such as: hacking tools for cryptocurrency wallets, "cracks" for digital wallet private keys (which grant users ownership of the funds on a given cryptowallet address), fake cryptocurrency senders (used to make bogus transactions when paying in said currency), brute-force tools (designed to generate numerous combinations in the hopes of finding correct passwords or passkeys) of various accounts (e.g., eBay, Facebook, etc.), gift card code generators (e.g., Amazon, etc.), and many others.

However, none of these applications operate as promised. Instead, when users click any of the buttons presented in their interfaces - HackBoss stealer's infection chain is initiated. The malicious program sets up a registry key to be run at startup and/or adds a scheduled task, which is to be repeated every minute.

This is the method HackBoss uses to ensure persistence. Therefore, even if its process is terminated using the Windows Task Manager, the stealer automatically runs after the system is started/booted. Alternatively, the malware can be run again per the next scheduled task, which repeat minutely.

The goal of the HackBoss stealer is to replace cryptowallet addresses copied into the clipboard with those belonging to the cyber criminals - when victims are making a cryptocurrency transaction. Thereby, as the intended recipients' address is pasted - the stealer actually pastes one of its own.

Therefore, rather than arrive into the chosen cryptowallet - the transaction is redirected to the criminals' wallet. To summarize, HackBoss infections can result in financial losses and other serious problems.

If it is known or suspected that the HackBoss stealer (or other malware) has already infected the system - an anti-virus must be used to remove it immediately.

Similar malware

Ares, Spectre, Xenon, and Sorano Bot are some examples of malicious programs that target cryptocurrency. In general, malware can have a wide variety of heinous functionalities, and these functions can be in different combinations.

Common features include: download/installation of additional malware, data encryption and/or screen locking for ransom purposes (ransomware), enablement of remote access and control over the infected machine (RATs - Remote Access Trojans), exfiltration (download) of content stored on the compromised system, information extraction from browsers and other installed applications, recording of keystrokes and/or audio/video, use of system resources to mine cryptocurrency (cryptominers), and so on.

Regardless of how malicious software operates, its sole goal is to generate revenue for the cyber criminals using it. All malware infections are dangerous, and as such - they must be eliminated immediately upon detection.

How did HackBoss infiltrate my computer?

As previously mentioned, HackBoss trojan is spread via fake apps, allegedly aimed at "hacking", "cracking", "cheating", or otherwise abusing various accounts, platforms, and services.

The bogus applications don varied disguises - they are supposedly designed to target cryptocurrency wallets, social networking and social media accounts, e-commerce platforms, etc. These apps are endorsed through Telegram and YouTube channels, blogs, and forums.

This is relatively standard in malware proliferation as malicious programs are often presented as or bundled with ordinary software/media.

They are also commonly distributed via untrustworthy download channels, e.g., unofficial and free file-hosting (freeware) websites, Peer-to-Peer sharing networks (Torrent clients, eMule, Gnutella, etc.), and other third-party downloaders. Illegal software activation ("cracking") tools and fake updates are prime examples of malware-spreading content, typically obtained from such dubious download sources.

"Cracks" can infect systems instead of activating licensed products. Illegitimate updaters cause infections by exploiting weaknesses of outdated programs and/or installing malicious software rather than the updates. Another popular malware-proliferation technique is distribution via spam campaigns.

This term defines a large-scale operation during which deceptive emails are sent by the thousand. The letters usually appear "official", "important", "urgent", and similar; they may even be disguised as mail from genuine institutions, authorities, organizations, companies, service providers, and other entities.

The scam emails have infectious files attached to and/or linked inside them. Virulent files can be in a variety of formats, e.g., archives (ZIP, RAR, etc.), executables (.exe, .run, etc.), PDF and Microsoft Office documents, JavaScript, and so forth.

When these files are opened - the infection process (i.e., download/installation of malicious programs) is triggered.

How to avoid installation of malware?

It is important to always research software before download/installation and/or purchase. It is strongly recommended to download only from official and verified sources. Additionally, all programs must be activated and updated with tools/functions provided by legitimate developers.

To avoid infecting the device via spam mail, it is advised against opening suspicious and irrelevant emails - especially any attachments or links found in them. It is crucial to have a reputable anti-virus/anti-spyware suite installed and updated.

Furthermore, this software has to be used to perform regular system scans and remove detected threats and issues. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

How to remove malware manually?

Most trojan infections can be removed by running a full system scan with Combo Cleaner. The full manual procedure below is for cases where automatic removal failed, where you want to verify a scan caught everything, or where the threat has multiple persistence points.

Tools you'll need

Combo Cleaner Antivirus 7-days free trial

Recommended primary scanner. VB100 certified. The 7-day free trial is available.

Microsoft Defender Offline Free · built-in

Built into Windows. Boots to a clean environment to catch rootkits.

Process Explorer Free

From Microsoft Sysinternals. Better than Task Manager - shows full paths and signatures.

Autoruns Free

From Microsoft Sysinternals. Lists every place malware can persist on your system.

Microsoft Safety Scanner (MSERT) Free

Official Microsoft on-demand scanner. Always-current signatures - expires every 10 days.

Phase 1~ 5 min

Contain - limit the damage

---

1

Disconnect from the network

30 secNo tool needed

Unplug your Ethernet cable and turn off Wi-Fi. If you're on a laptop, the airplane-mode key works fastest.

Why this matters

Many trojans exfiltrate data - saved browser passwords, banking sessions, screenshots - and accept remote commands. Cutting the network stops both immediately. Keep it disconnected until Phase 4.

2

Boot into Safe Mode with Networking

3 min

Safe Mode loads a minimal set of drivers and stops most malware from auto-running. "With Networking" lets you download tools - re-enable Wi-Fi only after you've booted in.

Windows 11

Open Settings → System → Recovery. Click Restart now next to Advanced startup.

Your computer will restart into the "Choose an option" menu. Click Troubleshoot → Advanced options → Startup Settings → Restart. After the second reboot, press 5 or F5.

Windows 10

Click the Windows logo, hold Shift, click the Power icon and choose Restart. In the Choose an option screen, click Troubleshoot → Advanced options → Startup Settings → Restart. Press F5.

Windows 8

Go to the Start Screen, type Advanced, select Settings → Advanced startup options → Restart now → Troubleshoot → Advanced options → Startup settings → Restart → F5.

Note: Windows 8 reached end-of-life in January 2023 - running on it puts you at much higher risk of reinfection.

Windows 7

Click Start → Shut Down → Restart → OK. As the system boots, press F8 repeatedly until the Windows Advanced Options menu appears, then choose Safe Mode with Networking.

Note: Windows 7 reached end-of-life in January 2020 - running on it puts you at much higher risk of reinfection.

Phase 2~ 15 min

Identify - find what's hiding

---

3

Inspect running processes with Process Explorer

Tool: Process Explorer5 min

Download Process Explorer from Microsoft Sysinternals. Run it as Administrator. Click Options → Verify Image Signatures and View → Lower Pane View → DLLs.

Sort by "Verified Signer." Anything unsigned running from %AppData%, %LocalAppData%, %Temp%, or %ProgramData% is suspicious. Right-click → Properties to see the full image path. Right-click → "Search Online" to look up unfamiliar process names.

Why not just Task Manager

Task Manager hides full file paths, doesn't show digital signatures, and groups processes in ways that make malware easy to miss. Process Explorer is the same tool Microsoft engineers use.

4

Map every persistence point with Autoruns

Tool: Autoruns 14.x10 min

Download Autoruns. Right-click Autoruns.exe and choose Run as administrator - without elevation, Autoruns can't inspect protected registry hives.

In the menu, open Options → Hide Microsoft Entries and Options → Hide Empty Locations, then click Refresh.

Modern trojans don't just live in startup. Walk through these tabs and look for unsigned or unfamiliar entries:

• Logon - classic Run/RunOnce keys
• Scheduled Tasks - frequent hiding spot, especially tasks with PowerShell, MSHTA, or rundll32 actions
• Services - unsigned services in non-Microsoft folders
• WMI - Event Subscriptions are a stealthy persistence mechanism (MITRE T1546.003)
• Image Hijacks - Image File Execution Options "Debugger" abuse
• AppInit - DLLs loaded into every GUI process
• Browser plug-ins - unsigned add-ons across all installed browsers

Pro tip

Right-click any suspicious entry → "Jump to Image" to see the actual file. Right-click → "Search Online" opens VirusTotal for the file hash. Don't delete yet - just write down the file paths and entry names. We'll remove them after the scans.

5

Check the hosts file and DNS settings

3 minBuilt into Windows

Trojans often redirect bank, antivirus, and update domains to attacker-controlled servers by editing the hosts file or DNS settings.

Hosts file: Open Notepad as Administrator and open C:\Windows\System32\drivers\etc\hosts. Legitimate entries are commented with #. Any uncommented IP-to-domain mapping is suspicious - especially redirects for microsoft.com, windowsupdate, or your bank.

DNS settings: Open Command Prompt as Administrator and run ipconfig /all. Confirm your DNS servers point to your ISP, your router, or a known public resolver (Cloudflare 1.1.1.1, Google 8.8.8.8). Then open Settings → Network & internet → [your adapter] → DNS server assignment and verify both DNS and DNS over HTTPS (DoH) settings haven't been hijacked.

Why this matters

A clean PC with hijacked DNS is still a compromised PC. You'll think you're at chase.com and you'll be at the attacker's clone.

Phase 3~ 60-90 min

Remove - three scans, one cleanup

---

No single antivirus catches everything. The order below is intentional: offline scan first (catches rootkits before Windows fully loads), then on-demand scanners on the running system, then manual cleanup of anything they missed.

6

Run Microsoft Defender Offline

Tool: Built into Windows15 min

Reboot to normal Windows. Open Windows Security → Virus & threat protection → Scan options. Select Microsoft Defender Antivirus (offline scan) and click Scan now. Your computer will restart into a stripped-down environment and scan before the full operating system loads.

Why this comes first

Rootkits and bootkits hide from any scanner running on the same Windows session that's already infected. A pre-boot offline scan sees the disk before the malware can hide itself.

Recommended antivirus

Combo Cleaner

VB100 certified. Includes anti-trojan, registry/persistence scanning, anti-spyware in one pass. The 7-day free trial is available.

Download Combo Cleaner

7

Run Combo Cleaner full system scan

Tool: Combo Cleaner20-40 min

Install Combo Cleaner and run a full system scan (not the quick scan). Let it complete fully, review the detected threats, and apply the recommended actions. Combo Cleaner will quarantine known trojans and registry persistence.

8

Run Microsoft Safety Scanner as a second-opinion scan

Tool: Microsoft Safety Scanner15 min

Download Microsoft Safety Scanner (MSERT.exe), Microsoft's free on-demand tool. The binary expires every 10 days, which means every download has the latest signatures. Run a full scan after Combo Cleaner to catch anything one engine alone might miss.

Why a second scan

Different scanning engines catch different threats. Running an additional Microsoft scan after Combo Cleaner is the single most underused verification step in malware removal.

9

Manually remove anything still listed in Autoruns

Tool: Autoruns10 min

Reopen Autoruns. Anything you flagged in Step 4 that's still present hasn't been caught by the automated scans. For each remaining suspicious entry: right-click → Delete in Autoruns (this removes the persistence registration), then navigate to the file path and delete the actual file. Empty the Recycle Bin.

Important

Some malware files reappear after deletion because something else on the system recreates them. If you delete a file and it returns within minutes, you have a remaining persistence point that Autoruns didn't show - usually a service or scheduled task running under SYSTEM. Re-run the scans from Steps 6-8 or proceed to a clean install (see end of guide).

Phase 4~ 15 min

Recover - restore browsers and security

---

10

Reset browsers and clear notification permissions

5 min

Trojans and adware frequently hijack browsers - change the default search engine, install rogue extensions, or grant themselves notification permissions to keep displaying scam pop-ups even after the malware is gone.

• Chrome: visit chrome://settings/reset and click "Restore settings to their original defaults." Then visit chrome://settings/content/notifications and remove any unfamiliar sites.
• Edge: visit edge://settings/reset. Then check edge://settings/content/notifications.
• Firefox: open about:support and click Refresh Firefox (Firefox uses "Refresh," not "Reset"). Then check Settings → Privacy & Security → Permissions → Notifications.

Review installed extensions in each browser and remove anything you don't recognize, especially extensions you didn't install yourself.

11

Re-enable Defender, Tamper Protection, and update everything

10 min

Many trojans disable security software. Open Windows Security → Virus & threat protection → Manage settings and confirm Real-time protection, Cloud-delivered protection, and Tamper Protection are all turned on. Tamper Protection prevents malware from disabling Defender silently.

Then run Windows Update (Settings → Windows Update → Check for updates) and update your browsers and applications. The infection vector that let the trojan in originally usually involves outdated software.

Phase 5~ 15 min + 7 days

Verify & secure

---

12

Change passwords from a clean device

20 min⚠ Critical

If the trojan was an info-stealer (Lumma, RedLine, Vidar, and similar are extremely common), assume every password saved in your browser is compromised. Change them from a different, known-clean device - your phone is fine if it's not infected.

Recommended order:

1. Primary email first - it's the recovery hub for everything else
2. Banking and financial accounts
3. Password manager master password (if you use one)
4. Social media, shopping, and remaining accounts

Where available, enable phishing-resistant multi-factor authentication (passkeys / FIDO2 hardware keys / authenticator apps) - SMS-based MFA is bypassable by sophisticated attackers.

13

Verify the clean and monitor for 7 days

5 min + 1 week monitoring

Reconnect to the network and run one final full scan with Combo Cleaner. Open Task Manager (Ctrl + Shift + Esc) and switch to the Startup apps tab - confirm nothing suspicious has reappeared.

Over the next 7 days, watch for symptom recurrence: unexpected high CPU usage, unknown processes returning, browser redirects, or pop-ups. If anything returns, you missed a persistence point and the procedure needs to be repeated - or you may have a deeper compromise that requires a clean install.

When to clean install Windows instead

Manual removal isn't always the right answer. Reinstalling Windows from scratch is the only way to be 100% certain when:

• The malware reappears after every removal attempt
• A bootkit or UEFI rootkit was detected (this class of threat sits below the operating system and survives a normal Windows reinstall)
• A confirmed credential-theft trojan ran with administrator privileges (Lumma, RedLine, Vidar) - the system likely has multiple unknown payloads
• The PC is used for online banking, business email, or anything where partial doubt isn't acceptable

A clean install is a 30-60 minute process: Windows 11 reinstall via Settings → System → Recovery → Reset this PC → Remove everything → Cloud download. Back up documents to external storage first, scan the backup with Combo Cleaner before restoring it, and reinstall applications fresh - never restore them from a backup of the infected system.

Important: Manual removal requires advanced computer skills. If you're not confident identifying system files from malicious files, run an automated scan with Combo Cleaner and Windows Defender and stop there - that path catches the vast majority of consumer trojans without the risk of breaking Windows by deleting the wrong file.
