Using the covert malware injection technique known as “process hollowing,” an attacker suspends a legitimate process, removes its original code, and replaces it with malicious code before the process resumes. Due to this, the virus can operate as a legitimate process and avoid being discovered by security programs.
As it enables the attacker to run malicious code under the disguise of a normal process and avoid detection by security tools, this technique is especially devious.
By concealing suspicious activity within a legitimate process scope, cybercriminals often use this technique as a camouflage approach to evade antivirus detection and perpetrate numerous cyber-felonies.
Implementing security measures and best practices, such as using process monitoring tools that can identify any abnormalities in process activity or changes in their memory, is crucial to preventing hollowing attacks. These technologies can assist in identifying possible attempts at process hollowing and notify administrators to conduct additional research.
For processes and their modules, routinely check the digital code signature and other validity indicators.Use robust endpoint security tools that can identify and stop process hollowing tactics.Update operating systems and software regularly.
