1-52450

This event is generated when an attempt to trigger a buffer overflow in the Squid caching proxy is observed.

1-52449

This event is generated when an outbound connection to ddns.net is detected. This could mean that a device is accessing a distributed DNS outside of its network and may be relying on an external service, instead of a trusted internal distributed DNS, to resolve its requests.

1-52448

This event is generated when a Doc.Malware.Gamaredon variant second stage download detected. This download will be an encoded text file that will later be decoded by the malware into an .exe file.
