A brand new clipboard hijacker is quietly draining cryptocurrency from avid gamers and streamers by abusing belief inside Discord communities.
The marketing campaign facilities on a malicious Home windows program shared as a supposed streaming or safety device. As soon as put in, it silently watches the person’s clipboard, ready for the second they copy a crypto pockets tackle.
When the sufferer pastes it into an change, pockets, or cost subject, the malware swaps it with an attacker-controlled tackle, redirecting the funds with out leaving apparent traces.
The menace actor, tracked as “RedLineCyber,” focuses on Discord servers linked to gaming, playing, and cryptocurrency streaming.
They construct rapport with server members, current themselves as device builders, and privately share a file named Professional.exe or peeek.exe.
Victims are advised the device will assist them handle or defend their pockets addresses throughout dwell periods, making it seem helpful quite than suspicious.
Behind this pleasant pitch is a targeted theft operation that may quietly empty transactions in a single mistyped paste.
CloudSEK analysts uncovered this operation whereas monitoring underground communities and Discord channels utilized by cybercriminals.
Throughout these human intelligence operations, researchers recognized the pretend “RedLine Options” persona and traced the malware again to a Python-based executable filled with PyInstaller.
Their evaluation confirmed that this system doesn’t behave like basic information-stealing malware, however as a substitute narrows its exercise to at least one process: manipulating clipboard knowledge linked to widespread cryptocurrencies.

The influence of this marketing campaign is critical as a result of it targets customers on the actual level the place human consideration is weakest. Many streamers and frequent merchants copy and paste lengthy pockets strings with out double-checking each character.
By working with out command-and-control visitors and utilizing minimal system sources, the malware can stay lively for lengthy intervals, ready for high-value transfers.
Blockchain traces linked to the attacker’s embedded pockets addresses already present stolen funds throughout Bitcoin, Ethereum, Solana, Dogecoin, Litecoin, and Tron.
An infection Mechanism and Clipboard Hijacking Logic
As soon as a sufferer launches Professional.exe, the malware creates a folder named CryptoClipboardGuard contained in the Home windows %APPDATA% listing and registers itself within the Run key of the present person’s registry.
This ensures it begins routinely each time the system boots, persisting within the background with none seen window.
The executable bundles its personal Python runtime and obfuscated bytecode, enabling it to run even on programs with out Python put in.
It then enters a decent loop, checking the clipboard roughly 3 times per second.

Each time the clipboard content material modifications, the malware scans it towards base64-encoded common expressions that match pockets codecs for main cryptocurrencies.
If it detects a sound tackle, it instantly overwrites the clipboard with a preset attacker pockets for that coin and information the swap in an exercise.log file inside %APPDATApercentCryptoClipboardGuard.

As a result of the tackle change occurs between copy and paste, most victims by no means discover the substitute till their funds arrive within the fallacious pockets — and by then, the switch is irreversible.
