As security measures get better at detecting and blocking both malware and cyberattacks, adversaries and cybercriminals are forced to constantly develop new techniques to evade detection. One of these advanced techniques involves “fileless" exploits, where no executable file is written to disk. These attacks are particularly effective at evading traditional antivirus (AV) solutions, which look for files saved to disk so they can scan them and determine if they are malicious. This report discusses these issues.
