About this technique
An adversary may rely upon specific actions by a user in order to gain execution. Users may be subjected to social engineering to get them to execute malicious code by, for example, opening a malicious document file or link. These user actions will typically be observed as follow-on behavior from forms of Phishing.
Read the full ATT&CK description
While User Execution frequently occurs shortly after Initial Access it may occur at other phases of an intrusion, such as when an adversary places a file in a shared directory or on a user's desktop hoping that a user will click on it. This activity may also be seen shortly after Internal Spearphishing.
Adversaries may also deceive users into performing actions such as:
* Enabling Remote Access Tools, allowing direct control of the system to the adversary * Running malicious JavaScript in their browser, allowing adversaries to Steal Web Session Cookies(Citation: Talos Roblox Scam 2023)(Citation: Krebs Discord Bookmarks 2023) * Downloading and executing malware for User Execution * Coerceing users to copy, paste, and execute malicious code manually(Citation: Reliaquest-execution)(Citation: proofpoint-selfpwn)
For example, tech support scams can be facilitated through Phishing, vishing, or various forms of user interaction.
Adversaries can use a combination of these methods, such as spoofing and promoting toll-free numbers or call centers that are used to direct victims to malicious websites, to deliver and execute payloads containing malware or Remote Access Tools.(Citation: Telephone Attack Delivery)
