This attack technique cleverly exploits OneDrive by placing a malicious version.dll file in its directory, ensuring that when OneDrive.exe launches, it unknowingly loads the harmful DLL before legitimate ones. By doing so, attackers can run their code under the guise of a trusted application. Notably, the malicious DLL mimics the functions of the real version.dll, allowing it to execute its operations quietly in the background without arousing suspicion.
The exploit employs advanced techniques like Vectored Exception Handling to redirect API calls, effectively avoiding detection from conventional security measures. The process maintains application functionality while allowing attackers to manipulate operations covertly. This dual functionality serves to keep security tools from spotting any anomalies, highlighting the sophistication of the attack.
To defend against such threats, security experts recommend implementing application whitelisting, monitoring DLL load behaviors, and validating the digital signatures of loaded libraries. These measures aim to thwart attacks that leverage trusted apps like OneDrive, which many organizations rely on in their daily operations.
