DanaBot is a sophisticated banking trojan that first emerged in 2018 and continues to evolve with new capabilities. Unlike ransomware that demands immediate payment, this malware is designed for the long game — establishing persistent access to your system while quietly harvesting banking credentials, cryptocurrency wallets, email logins, and other financially valuable information. What makes DanaBot particularly dangerous is its modular architecture, allowing attackers to download additional components after the initial infection, effectively turning your computer into a customizable espionage platform.
Initially targeting users in Australia and Europe, DanaBot campaigns have since expanded globally with well-crafted phishing emails that appear remarkably legitimate. The malware operators favor quality over quantity, sending relatively small volumes of highly convincing emails rather than mass spam campaigns. This focused approach makes DanaBot infections less common than broad-spectrum threats, but significantly more dangerous when they occur.

How It Spreads
DanaBot operators invest significant effort in social engineering, crafting convincing phishing emails that appear to come from legitimate businesses, financial institutions, or shipping companies. These aren't the obviously fake "Nigerian prince" scams — they use proper grammar, official-looking logos, and timely subjects like tax season deadlines or package delivery notifications. The emails typically contain Microsoft Office documents (Word or Excel) with malicious macros, or direct executable attachments disguised as invoices, receipts, or shipping labels.
Once you open the attached document and enable macros (which the document will request under some business-sounding pretext), the initial dropper component downloads and executes the full DanaBot payload. In some campaigns, the malware has also been distributed through compromised websites via exploit kits that target unpatched browser vulnerabilities, and through malicious advertisements (malvertising) on otherwise legitimate websites.
Common distribution vectors include:
- Email attachments — Microsoft Office documents (.doc, .xls) with macro-enabled malware droppers
- Malicious links — URLs in phishing emails that download executables disguised as PDF documents or invoices
- Compromised websites — Legitimate sites infected with exploit kit code that silently downloads DanaBot when visited
- Software bundling — Pirated software or fake installers that include DanaBot as a hidden component
- Malvertising campaigns — Malicious advertisements on legitimate websites that redirect to exploit kit landing pages
- Watering hole attacks — Compromising websites frequented by specific target industries or demographics
What It Does On Your Machine
DanaBot's modular design means the initial infection is just the beginning. The core component establishes persistence on your system, then contacts command-and-control servers to download additional modules based on what the attackers want to steal from your particular system. These modules can include screen capture tools, keyloggers, cryptocurrency wallet stealers, browser credential harvesters, email collectors, and even remote access capabilities that let attackers directly control your machine.
The banking trojan components specifically target financial institutions by monitoring your browser activity and injecting fake login forms or payment pages that capture your credentials as you type them. This "web injection" technique is nearly invisible to victims — you see what appears to be your bank's normal login page, but it's been modified to send your username and password to the attackers. DanaBot maintains lists of targeted banks and cryptocurrency exchanges, updating these lists from its command servers to stay current with new targets.
Beyond credential theft, DanaBot establishes deep system access that allows attackers to use your infected machine as a foothold for broader network compromise. In business environments, this can lead to lateral movement across your network, potentially compromising additional computers, servers, and sensitive company data. The malware also has been observed downloading secondary payloads including ransomware, effectively selling access to other criminal groups.
The malware employs several anti-analysis techniques to avoid detection by security software. It checks for virtualized or sandbox environments before executing its payload, uses encrypted communications with command servers, and can detect debugging tools that researchers use to analyze malware. These evasion capabilities mean traditional antivirus software may not detect DanaBot until after significant damage has occurred.
Manual Removal — Step by Step
Disconnect and Boot to Safe Mode
Immediately disconnect the infected computer from the internet (unplug ethernet or disable WiFi). Restart in Safe Mode with Networking by holding Shift while clicking Restart, then selecting Troubleshoot > Advanced Options > Startup Settings > Restart > press 5 for Safe Mode with Networking. This prevents DanaBot from communicating with command servers while allowing you to download removal tools.
Document Your Banking and Email Accounts
Before proceeding with removal, use a clean device (not the infected computer) to immediately change passwords for all banking, email, and cryptocurrency accounts. Contact your financial institutions to alert them of potential compromise. DanaBot may have already transmitted stolen credentials, so speed is critical to prevent fraudulent transactions.
Run Multiple Specialized Scanners
Download and run Malwarebytes, HitmanPro, and ESET Online Scanner from a clean computer, transfer via USB drive to the infected machine. Run full system scans with all three tools sequentially. DanaBot's modular nature means one scanner may miss components another will catch. Quarantine all detections but don't delete yet — you may need the samples for forensic analysis if financial fraud has occurred.
Check Startup Locations and Scheduled Tasks
Open Task Manager (Ctrl+Shift+Esc), click the Startup tab and look for unfamiliar entries, especially those with random names or pointing to %APPDATA% folders. Open Task Scheduler (taskschd.msc) and examine the Task Scheduler Library for suspicious tasks created recently. Document anything unusual before disabling — DanaBot often creates multiple persistence mechanisms as backup.
Manually Inspect Critical Registry Keys
Open Registry Editor (regedit.exe) and navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run and HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run. Look for entries with random names or paths to %APPDATA% or %TEMP% directories. Also check HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services for suspicious service entries. Export any suspicious keys before deletion for documentation.
Remove Browser Extensions and Clear Data
Open each installed browser (Chrome, Firefox, Edge) and navigate to the extensions/add-ons page. Remove any extensions you don't recognize or didn't intentionally install. Then clear all browsing data including cached files, cookies, and saved passwords. DanaBot's web injection components often install malicious browser extensions to maintain persistence even after the main executable is removed.
Search for Randomly-Named Executables
Use File Explorer to search %APPDATA%, %LOCALAPPDATA%, and %TEMP% directories for recently created .exe and .dll files, especially those with random character names. Sort by date modified to identify files created around the time of infection. DanaBot often drops multiple components with randomized names to avoid simple signature detection.
Verify Network Configuration
Check your network proxy settings in Control Panel > Internet Options > Connections > LAN Settings. DanaBot sometimes configures proxy servers to intercept all web traffic. Also review your hosts file at C:\Windows\System32\drivers\etc\hosts for malicious redirections. Any entries pointing banking websites to local or foreign IP addresses indicate active web injection attacks.
Scan All Network-Connected Devices
If this computer is part of a home or business network, assume lateral movement has occurred. Scan every connected device with updated antivirus software. DanaBot has been observed spreading through network shares and can compromise additional systems to establish redundant access points. Change all network passwords including WiFi credentials.
Consider Complete System Reinstall
Given DanaBot's sophisticated evasion capabilities and modular design, the only way to be absolutely certain of complete removal is a full Windows reinstall from trusted media. If this computer held sensitive financial or business data, we strongly recommend professional forensic analysis before reinstallation to document the scope of compromise for insurance or legal purposes. This isn't paranoia — it's due diligence when dealing with advanced banking trojans.
Prevention
- Disable macros by default — Configure Microsoft Office to disable macros in documents from untrusted sources. Most legitimate documents don't require macros, and this single setting blocks the majority of DanaBot infections. If a document requests you enable macros to view content, it's almost certainly malicious.
- Scrutinize email attachments ruthlessly — Even if an email appears legitimate, verify unexpected attachments by contacting the sender through a separate communication channel (phone call, not reply email). Attackers spoof sender addresses and hijack legitimate email threads to appear trustworthy. When in doubt, don't open it.
- Keep all software updated — Enable automatic updates for Windows, browsers, Adobe products, and Java. DanaBot campaigns often exploit known vulnerabilities in outdated software. Exploit kits specifically target systems running old browser versions or unpatched plugins.
- Use a dedicated computer for financial transactions — If possible, maintain one computer exclusively for banking and sensitive financial activities. Don't use this machine for general web browsing, email, or downloading software. This isolation significantly reduces exposure to banking trojans like DanaBot.
- Implement DNS-level filtering — Services like OpenDNS or Cloudflare for Families block access to known malicious domains at the network level, preventing your computer from contacting command-and-control servers even if the malware executes. This won't stop the initial infection but can limit data exfiltration.
- Enable two-factor authentication everywhere — Even if DanaBot steals your banking password, 2FA using a separate device (phone app, hardware key) can prevent unauthorized access. Avoid SMS-based 2FA when possible — opt for authenticator apps or hardware tokens which are more resistant to interception.
- Regular offline backups — Maintain encrypted backups of critical data on external drives that remain disconnected when not actively backing up. DanaBot infections sometimes lead to secondary ransomware deployment. Offline backups ensure you can recover without paying ransom.
- Monitor financial accounts actively — Review bank and credit card statements weekly, not monthly. Enable transaction alerts for unusual activity. Early detection of unauthorized charges can limit damage and help law enforcement track the criminal operation.
