High Volume of Lambda Activity Detected

AWS Lambda is a very popular service where development operations occur native to the cloud without the need to deploy expensive servers or equipment. Because of this environment, it can be a prime target for attackers to take advantage of. As malware relies on a program of some sort, code will need to be run in order to carry out malicious operations. An output of high volume with Lambda events is an indication of an attacker using this service for their own gain. CUIT deploys signatures to detect potential unauthorized content.
