Here is an example of how we detected Emotet infection on an analysis system using OTX Endpoint Threat Hunter. Get started with OTX Endpoint Threat Hunter Free: OTX Endpoint Threat Hunter allows anyone to determine if their endpoints are infected with the latest malware or other threats by manually scanning their endpoints for the presence of indicators of compromise (IoCs) that are catalogued in OTX. In April, AlienVault introduced the Endpoint Threat Hunter - a free threat-scanning service in Open Threat Exchange® (OTX™) based on the AlienVault Agent. Try it for yourself in the USM Anywhere Online Demo. This allows USM Anywhere to deliver endpoint detection and response (EDR), file integrity monitoring (FIM), and rich endpoint telemetry capabilities that are essential for complete and effective threat detection, response, and compliance. In USM Anywhere, the AlienVault Agent enables continuous endpoint monitoring, using the built-in AlienVault threat intelligence to automate endpoint queries and threat detection alongside your other network and cloud security events. The AlienVault Agent is a lightweight, adaptable endpoint agent based on Osquery and maintained by AlienVault. This can be extremely helpful for investigating security incidents as well as threat hunting activities on your critical assets.ĪlienVault leverages Osquery through the AlienVault Agent to enable threat hunting in both USM Anywhere and the Open Threat Exchange. Osquery allows you to retrieve a wealth of events and useful information from your endpoints. There is one directory called ‘/inc’ which was listing files and folder of the website.As we have seen, it is possible to analyze malware and extract valuable information using tools like Osquery that give us rich visibility of systems events. $gobuster dir -u $IP/content/ -w /usr/share/wordlists/dirbuster/ = Gobuster v3.1.0 by OJ Reeves & Christian Mehlmauer = Url: Method: GET Threads: 10 Wordlist: /usr/share/wordlists/dirbuster/ Negative Status codes: 404 User Agent: gobuster/3.1.0 Timeout: 10s = 4 13:49:53 Starting gobuster in directory enumeration mode = /images (Status: 301) /js (Status: 301) /inc (Status: 301) /as (Status: 301) /_themes (Status: 301) /attachment (Status: 301) Now let us again run the gobuster on this endpoint to see what we can find further. It was running was running CMS of Sweetrice. So now we know HTTP website is running on the system so let’s take a look Here we found out that there are 2 ports open i.e 80 and 22 which is also for HTTP and SSH.

I used to rustscan and forward the result to Nmap We start to gather information by scanning open ports in the system. Hello People, In this write up I have covered a walkthrough for the Tryhackme box called Lazy Admin.
