The malicious code can be programmed to launch every time the OS is launched, and there is no malicious file that could be discovered – the malicious code is hidden in native files not subject to AV detection. Instead, the dropper program itself writes malicious code straight into the Windows registry. Fileless malware may also use a dropper program, but it doesn’t download a malicious file. This malicious file remains active on the targeted system, which makes it vulnerable to detection by antivirus software. Registry resident malware is malware that installs itself in the Windows registry in order to remain persistent while evading detection.Ĭommonly, Windows systems are infected through the use of a dropper program that downloads a malicious file. In some cases, the exploit kit will include the ability to scan the targeted system for vulnerabilities and then craft and launch a customized exploit on the fly. The exploit kit usually includes exploits for a number of vulnerabilities and a management console that the attacker can use to control the system. Typically, a victim is lured through a phishing email or social engineering. Adversaries can use them to automate initial compromises at scale.Īn exploit begins in the same way, regardless of whether the attack is fileless or uses traditional malware. Adversaries use these tools to take advantage of vulnerabilities that are known to exist in an operating system or an installed application.Įxploits are an efficient way to launch a fileless malware attack because they can be injected directly into memory without requiring anything to be written to disk. Access and attacks can be accomplished in several ways, such as through the use of:Įxploits are pieces of code, sequences of commands, or collections of data, and exploit kits are collections of exploits.

While attackers don’t have to install code to launch a fileless malware attack, they still need to get access to the environment so they can modify its native tools to serve their purposes. This fileless technique of using native tools to conduct a malicious attack is called “living off the land.” Common Fileless Malware Techniques
Unlike traditional malware, fileless malware does not require an attacker to install any code on a target’s system, making it hard to detect. Fileless malware is a type of malicious activity that uses native, legitimate tools built into a system to execute a cyber attack.
