Wish Stealer operates with precision and subtlety, leveraging advanced techniques that allow it to avoid detection while accessing critical data stored on infected devices. By silently bypassing antivirus defenses and embedding itself into common applications, it maintains a low profile, often escaping the notice of traditional security tools.
Key Abilities of Wish Stealer
Wish Stealer is armed with multiple capabilities, each tailored to maximize its impact and minimize its detectability:
1. Credential Harvesting
Wish Stealer systematically extracts login credentials, cookies, and even credit card information from targeted applications, enabling attackers to gain unauthorized access to a range of accounts, from social media to online banking. With this data in hand, attackers can impersonate victims, conduct fraudulent transactions, and further spread their attacks by exploiting additional connected accounts.
2. Clipboard Monitoring for Crypto Transactions
One of Wish Stealer’s more insidious features is its clipboard manipulation, which specifically targets cryptocurrency wallet addresses. By monitoring clipboard activity, it identifies when a cryptocurrency address is copied and swiftly replaces it with the hacker’s address. This silent, real-time replacement tactic increases the risk of users unknowingly transferring their funds to an attacker’s wallet.
Example: If a user copies their Bitcoin wallet address to paste into a transaction, Wish Stealer intercepts and substitutes it with an attacker-controlled address. The user, unaware of the switch, may lose their funds in a single transaction.
3. Antivirus Bypass
Wish Stealer actively disables certain antivirus programs, allowing it to evade immediate detection and continue its operations without interruption. By exploiting weaknesses in antivirus software, it can operate undisturbed, gathering and exfiltrating data while the user remains unaware of its presence. This bypass function is particularly effective against systems with outdated or less robust antivirus solutions.
4. Session Hijacking to Bypass MFA
Wish Stealer’s session hijacking feature is a potent addition to its toolkit. By capturing session cookies, it can bypass multi-factor authentication (MFA), allowing attackers to access protected accounts without needing additional verification. This is especially dangerous for users relying on MFA as their primary defense, as it allows the attacker to maintain persistent access to the account.
Wish Stealer combines stealth with multi-layered attack strategies, making it a formidable opponent against traditional security measures. With advanced data theft and session hijacking capabilities, it represents a new class of malware that integrates seamlessly into everyday applications, posing a substantial threat to users’ financial and personal information.

hideConsole,antiDebug,killProcess, anddiscordInjectionare executed in a precise sequence to ensure the malware operates undetected. - Evasion Tactics: The
hideConsolefunction conceals the malware’s presence by preventing it from showing in active task lists or command prompts. Meanwhile,antiDebugemploys anti-debugging measures to avoid detection from reverse-engineering tools, a common cybersecurity countermeasure. - Process Control: The
killProcessfunction disables select security processes on the victim’s machine, whilediscordInjectionallows the malware to interact with Discord, a popular communication platform.
This multi-layered initiation ensures the malware remains hidden and undisturbed, making it more effective in extracting sensitive data from the system.
2. Crypto Clipper Manipulation
One of Wish Stealer’s more dangerous features is its crypto clipper functionality, which manipulates clipboard content to intercept cryptocurrency transactions:
- Clipboard Monitoring: Every three seconds, the malware uses PowerShell commands, such as
Get-ClipboardandSet-Clipboard, to monitor and alter clipboard content. - Crypto Redirection: If a cryptocurrency wallet address is detected, Wish Stealer replaces it with a hacker-controlled address. This deceptive “clipboard hijacking” exploits users’ trust in their copied data, leaving victims unaware that their funds are being redirected.
Example: Imagine copying a Bitcoin address to transfer funds to a secure wallet. Wish Stealer’s crypto clipper quickly replaces this address with the hacker’s address. When the user pastes, the funds go to the attacker’s wallet without the victim’s knowledge.
3. Session Hijacking for Social Media Accounts
Wish Stealer also excels in session stealing, particularly for social media and communication platforms, enabling access without needing credentials:
- Session Cookie Theft: By scanning the AppData folder, Wish Stealer can locate stored session cookies for applications like Discord, Twitter, and other platforms.
- Multi-Factor Authentication Bypass: With access to session cookies, Wish Stealer effectively bypasses MFA. This allows attackers to assume control of accounts without additional verification, sidestepping a key security layer.
Example: Once Wish Stealer captures a session cookie from Discord, the attacker can log in as the user, gaining full access to the account without the user receiving any authentication alerts.
4. Stealth and Persistence Mechanisms
To avoid detection and maintain control over infected systems, Wish Stealer uses advanced persistence techniques:
- File Concealment: The malware copies itself into
$APPDATAMicrosoftProtect, naming itselfWindowsSecurityHealthService.exeto appear as a legitimate system file. - Startup Configuration: By adding itself to the system’s startup programs, Wish Stealer ensures it runs on every boot, reestablishing its hold on the system even after a restart.
- Hidden Attributes: It applies “hidden” and “system” attributes to make its file difficult to find, adding an extra layer of persistence against casual attempts to remove it.
5. Extraction of Browser and Wallet Data
Wish Stealer’s data theft capabilities are particularly harmful for users with sensitive data stored in browsers or cryptocurrency wallets:
- Browser Data Theft: Targeting Chromium-based browsers, including Chrome and Edge, Wish Stealer decrypts and collects sensitive information, such as stored passwords, cookies, and browsing history.
- Cryptocurrency Wallet Access: The malware accesses popular crypto wallet applications (e.g., MetaMask, Trust Wallet, Binance) and extracts stored data, like private keys or passphrases, which are essential for wallet security. This data is then packaged and sent to the attacker, compromising the user’s digital assets.
Wish Stealer uses a combination of stealth, clipboard manipulation, session hijacking, and data theft to access and exfiltrate sensitive information without triggering conventional security alerts. It exemplifies a new level of sophistication in malware, exploiting common applications and user habits to remain effective and undetected.
