Exploit memory HeapSpray attempt blocked - Internet Explorer

Recommended Posts

We just rolled out the last Anti-Exploit Version: 1.12.2.147 to our test Endpoints

One of the Clients (windows-10 virtual machine) got this alert-message as soon as he tries to open Internet Explorer.

Malwarebytes management server emailed over a notice about this alert every times the client tries to open IE.

Below is the alert-message from Server and attached are the MBAE Logs from that VM.
