DoubleFinger Malware – Your Crypto Is Now a Target

by admin

The DoubleFinger operation commences with an innocent-looking email containing a malicious PIF attachment. Upon opening, the attack unfolds in a series of intricately orchestrated stages.

Stage 1: DoubleFinger starts by manipulating a Windows binary, “espexe.exe,” leveraging a malicious shellcode executed through a patched DialogFunc. This shellcode discreetly retrieves an image from, concealing an encrypted payload within.

Stage 2: The second stage employs a legitimate Java binary named “msvcr100.dll” to load and decrypt the third-stage shellcode. This step emulates the structure and functionality of the first stage, revealing the attackers’ adeptness at maintaining a façade of legitimacy.

Stage 3: Diverging significantly from the prior stages, the third stage employs advanced tactics, utilizing low-level Windows API calls and ntdll.dll mapping to evade security hooks. The encrypted payload from the downloaded PNG image is decrypted and executed, enabling the transition to the next phase.

Stage 4: Simplicity characterizes the fourth stage, as it locates and employs the Process Doppelgänging technique to execute the fifth stage.

Stage 5: The fifth and final stage ensues with the installation of the GreetingGhoul cryptostealer. This malicious software conducts two critical operations: identifying cryptocurrency wallets, seizing private keys and seed phrases, and overlaying legitimate cryptocurrency application interfaces to intercept user input. It grants cybercriminals control over victims’ wallets, allowing them to abscond with funds.

Notably, the DoubleFinger campaign exhibits a high level of technical sophistication akin to advanced persistent threats (APTs). Its multi-stage progression from a seemingly harmless email attachment underscores its covert and strategic nature.

The threat does not stop with cryptocurrency theft. Some iterations of DoubleFinger incorporate the notorious Remcos remote access Trojan, empowering cyber criminals with comprehensive control over infected systems. By observing user actions and seizing system reins, Remcos amplifies the assailants’ dominion.

In summary, the DoubleFinger loader stands as a formidable testament to the evolving tactics of cryptocurrency theft. Its multi-stage structure, underpinned by legitimate binaries and advanced evasion techniques, reinforces the importance of robust cybersecurity measures in safeguarding against such covert and persistent threats.
