Payouts King: Spam Bomb Followed by Teams External Message and Quick Assist Launch
This rule detects a multi-stage attack sequence where a user is subjected to a 'spam bomb' (large volume of inbound emails in a short time), followed by an external Microsoft Teams contact, and concluding with the execution of legitimate remote support tools (Quick Assist or MSRA) on the victim's endpoint, which is a common pattern for social engineering and technical support fraud.
