The following analytic detects the execution of known remote access software within the environment.
It leverages network logs mapped to the Web data model, identifying specific URLs and user agents associated with remote access tools like AnyDesk, GoToMyPC, LogMeIn, and TeamViewer.
This activity is significant as adversaries often use these utilities to maintain unauthorized remote access. If confirmed malicious, this could allow attackers to control systems remotely, exfiltrate data, or further compromise the network, posing a severe security risk.

Detects requests through WebSEAL whose URI or query string carries exploitation
characteristics. As a reverse proxy, WebSEAL sees the full request before it reaches
the application, which makes it the right place to catch attempts against back-end
systems that log very little themselves.

Onboarding: ISAM-WEBSEAL is ingested via Syslog (Bloo extractor 85).
Integration guide: https://bloo.io/docs/hypercloud/syslog-connector

BQL (Bloo Query Language):

stream=webserver where sourcename='ISAM-WEBSEAL'
| groupby url, uriquery, method, returncode, srcip, useragent
