A sophisticated new cybercrime operation is preying on the trust of the cryptocurrency community by masquerading as a notorious threat group. CloudSEK’s STRIKE team has uncovered “RedLineCyber,” a threat actor who poses as an affiliate of the infamous “RedLine Solutions” to distribute a stealthy clipboard hijacker designed to drain digital wallets.
The campaign, uncovered through human intelligence (HUMINT) operations in December 2025, targets high-value victims where they feel safest: private Discord communities focused on gaming, gambling, and streaming.
The core of this operation is a calculated identity theft. The attacker doesn’t just spread malware; they build a persona. According to the report, “The actor masquerades as an affiliate of ‘RedLine Solutions,’ deliberately leveraging the notoriety of the well-known RedLine infostealer family to establish false credibility within underground communities”.
By adopting the branding of a “top-tier” malware family, the attacker lowers the guard of potential victims, positioning their malicious tool as legitimate software.
The attack vector is personal and patient. Rather than spraying phishing emails, RedLineCyber infiltrates Discord servers—specifically those like discord.gg/watchgamestv and discord.gg/lootbox—to groom victims.
“Distribution occurs through direct social engineering, where the actor cultivates relationships with potential victims, particularly cryptocurrency streamers and influencers, over extended periods before introducing the malicious payload”.
The malware, often named “Pro.exe” or “peeek.exe”, is pitched as a “security tool” or “streaming utility” designed to help influencers manage their broadcasts safely.
Once installed, the malware behaves differently from the noisy “smash-and-grab” tactics of traditional infostealers. It is a clipboard hijacker (or “clipper”) written in Python.
“Unlike traditional infostealers that collect broad system data, this malware employs a highly targeted approach: it continuously monitors the Windows clipboard for cryptocurrency wallet addresses and performs real-time substitution with attacker-controlled addresses”.
This means the victim only realizes the theft has occurred after they have pasted an address and confirmed a transaction, sending their funds directly to the attacker. The malware targets six major cryptocurrencies: Bitcoin, Ethereum, Solana, Dogecoin, Litecoin, and Tron.
The technical analysis reveals a distinct effort to remain invisible. Unlike the real RedLine Stealer (which is C# based and chatty), this imposter malware operates almost entirely offline.
“The malware’s narrow operational focus, clipboard monitoring without network communication or data exfiltration, allows it to maintain a low detection profile”.
By not communicating with a Command and Control (C2) server, the malware avoids tripping network firewalls, lying in wait until the exact moment a transaction is made.
