What is dll hijacking?
DLL Hijacking is an attack type where an attacker exploits a vulnerability in software to load malicious DLL files.
Azərbaycanca: DLL Hijacking zəifliyi proqram təminatının zərərli DLL fayllarını yükləməsinə səbəb olan hücum növüdür.
How it works
During a DLL Hijacking attack, an attacker places a malicious DLL file in the search path of a program and tricks the program into loading it. This allows the attacker to execute arbitrary code.
Defense checklist5
- 01
Secure the search path for DLL files loaded by software
- 02
Verify the signatures of DLL files
- 03
Configure permissions correctly to limit an attacker's write access
- 04
Regularly update software and DLL files
- 05
Use security software and EDR solutions
