Threat Hunting for Non-Hunters

Threat hunting is a proactive task with an assumption that your organization has already been breached and you wanted to beat the average “dwell time” of 256 days; at least for me as a DFIR practitioner. And this is usually done with the help of different tools that we call “arsenals”; SIEM (security information and event management) and EDR (endpoint detection and response) mostly.

However, security is not just for the IT security folks who are paid mainly to do this kind of “Blue Teaming” work (aka Incident Responders) but it is everyone’s responsibility.

Human is the weakest link among the security chain so as an end-user, anyone should have the basic understanding of how tofind malicious activities and files within their workstations.

The malware or malicious software includes but not limited to Keylogger, credential stealerscrypto minerreverse shellransomwarebotnet, and more.

This article aims to empower non-security folks to gain a portion of technical knowledge on hunting threats from their Windowssystems and able to share to their families and friends as well using freely available and downloadable tools from the Internet.

Hunting Persistent Threat with Autorun Programs

There are so huge places in the system that an adversary can plant their malicious programs and run automatically during boottime without an end-user’s awareness.

Tools from Sysinternals Suite by Microsoft Windows; “autorunsc.exe” (command-line) and “Autoruns.exe” (graphical user interface) can help to see all Autorun programs in your machine which can be downloaded on the link below.

Download URL:

Adding the parameter “hyphen h” (-h) to the command autorunsc.exe will give you the MD5 or SHA-256 hashes of the file to check from the Open Source Intelligence (OSInt) websites for Malicious file and URL called VirusTotal(


autorunsc.exe –h

The output can also be redirected to a text file for reference and easy recording.


autorunsc.exe -h > autoruns.txt

“autorunsc.exe –help” will give you more choices to play around with the command-line tool on Windows.

More often, the graphical version of the Autoruns would be preferable to others as a simple right-click on the mouse will give you an option to check the program in VirusTotal on the spot.

Threat Hunting Hidden Processes

Anti-Virus (AV) whether traditional or call themselves as “Next-Gen AV” misses more than 70% of malware according to research and it is because they are still signature-based. And sophisticated malicious programs runs as hidden processes to evade AV detections.

The most common of this kind of malware is “rootkit”, a malicious program that runs on the system’s kernel or memory.

Below are the useful tools that can be utilized against this persistent threat on anyone’s PC.


GMER is an awesome tool in detecting rogue processes that can be downloaded here:

This is a PE (portable executable) tool similar to SysInternal Suites and other tools that are mentioned here.

With the aid of the tool from SysInternal Suite – procexp64.exe (for 64bit Windows system), the tool was found spawning different DLL’s and processes which was also identified as malicious based from the Indicators of Compromised or IOC found from VirusTotal –

Threat Hunting Command & Control

Command & Control or C2 or C&C is a computer server that gives directives to digital devices commonly computers and smartphones that have been infected with rootkit or malware such as Ransomware and other variants. These infected devicesare called “bots” or “botnet” for Robot. Botnets are also used for sending Spam and Distributed Denial of Service (DDOS) attack against the target.

Known C2 servers will be most likely detected by Firewall if it is enabled in a PC or company provided workstation. Except for “zero day” attack when the C2 server is not yet identified by the EDR and Firewall companies.

This may sound a little technical but good to know when needed since the tool of example will be used here is already included in Windows systems.

By opening the command prompt or CMD as administrator, you will be able to run the tool called NETSTAT.

In the command prompt, just type the tool command below with a hyphen “ano” (-ano), parameters to display all networkconnections, with port numbers, and process ID’s. The parameter “f” is useful to see the fully qualified domain name or simply as the website address of the established connections over the internet for quick identification.


netstat –ano

netstat –af

The tool will be prompted with few lines depending on how many tabs open in the browsers when connected to the internet and it will also include the connection in C&C if the host machine is infected with malware or botnet.

This network threat hunting process may take a few minutes as it needs to go through the public IP addresses which are LISTENING and ESTABLISHED for checking from OSInt like VirusTotal, OTX, and other websites that provide IOC’s based from IP’s.

If there is no IOC found from the OSINT, a healthy paranoia will be needed to stop the running processes based from the PID (process id) resulted from the NETSTAT tool by simply running the “TASK MANAGER” through typing the “CTRL+ALT+DELETE” at the same time. Find the PID under the DETAILS tab, mouse right-click on it and “END TASK”.

Threat Hunting Malware

Malicious program threat hunting is different from running an Anti-Virus as it does not need to be quarantined or remove immediately. By running an AV may notify the malware creator that the malicious program planted in the host machine has been found and deleted which the adversary will be warned for detection.

“Triaging” an advanced persistent threat (APT) is crucial in hunting the threat actor and tracing their whereabouts.

A simple IOC scanner called LOKI is effective for that detective role playing like Sherlock Holmes.

This slick tool can be downloaded here:

The tool will give the full directory of both suspicious and malicious file based from its IOC’s that most AV’s does not have yet and may able to delete manually or opt for further malware analysis which is an interesting hobby.

Threat Hunting Rogue Wi-Fi

In my few speaking engagements, I always mention that “Free” is not always good as this is can be a conduit for Social Engineering attacks like Man-In-The-Middle (MITM) or Eaves Dropping technique to steal sensitive information.

It is best to have a healthy paranoia to run tools like my example here to catch rogue access points (AP) in the public.

A handy rogue AP killer and a user-friendly tool called CHELLAM is very useful to stay safe in the wild while the adversary is just one click away to bait their targets and one could be you or your family.


There are so many available tools that can be downloaded in the wild and it is everyone’s discretion on what tool is effective for the individual. As mentioned in my other blogs, a mindset of a hunter is the most important and that cannot be taken from classroom training nor in Ph.D. degree. Again, security is everybody’s responsibility and either you are part of the solution or just another brick in the wall.

Most Important Security Tools and Resources For Security Researcher, Malware Analyst, Reverse Engineer

Important Tools and Resources

Security Professionals always need to learn many tools , techniques and concepts to analyze sophisticated Threats and current cyber attacks.

Here we are going to see some of the most important tools , books, Resources which is mainly using for Malware Analysis and Reverse Engineering.

Hex Editors

A hex editor (or binary file editor or byteeditor) is a type of computer program that allows for manipulation of the fundamental binary data that constitutes a computer file. The name ‘hex’ comes from ‘hexadecimal’: a standard numerical format for representing binary data.


disassembler is a computer program that translates machine language into assembly language—the inverse operation to that of an assembler.

A disassembler differs from a decompiler, which targets a high-level language rather than an assembly language. Disassembly, the output of a disassembler, is often formatted for human-readability rather than suitability for input to an assembler, making it principally a reverse-engineering tool.

Indicator Of Attack(IoA’s) And Activities – SOC/SIEM – A Detailed Explanation


What is an Indicator of Attack (IOA)

IoAs is some events that could reveal an active attack before indicators of compromise become visible. Use of IoAs provides a way to shift from reactive cleanup/recovery to a proactive mode, where attackers are disrupted and blocked before they achieve their goal such as data thief, ransomware, exploit, etc.

IOAs focus on detecting the intent of what an attacker is trying to accomplish, regardless of the malware or exploit used in an attack. Just like AV signatures, an IOC-based detection approach cannot detect the increasing threats from malware-free intrusions and zero-day exploits. As a result, next-generation security solutions are moving to an IOA-based approach

10 Indicators of attack (IoAs)

The following most common attack activities could have been used, individually or in combination, to diagnose active attacks:

1) Internal hosts with bad destinations

Internal hosts communicating with known bad destinations or to a foreign country where you don’t conduct business.


An example of HP ArcSight Dashboard that shows client’s hosts communicating with Feeds(IP, Domain, Url) from “” website.


Example of Global Threat Intelligence from McAfee

2) Internal hosts with non-standard ports

Internal hosts communicating to external hosts using non-standard ports or protocol/port mismatches, such as sending command shells (SSH) rather than HTTP, HTTPS traffic over port 80,443, the default web port.


Example of Internal Host using 21(FTP), 445(SMB), 137(NETBIOS-NS), 135(RPC) to the Internet

3) Public Servers/DMZ to Internal hosts

Publically servers or demilitarized zone (DMZ) hosts communicating to internal hosts. This allows leapfrogging from the outside to the inside and back, permitting data exfiltration and remote access to assets such as RDP(Remote Desktop Protocol), Radmin, SSH.


An example of a Report that monitor Top 10 Traffic from “DMZ” zone to “Internal/Client” Zone.

From this report, Security Analyst should investigate to Highlighted Servers that communicating to Internal hosts via RDP(TCP/3389), SSH(TCP/22)

4) Off-hour Malware Detection

Alerts that occur outside standard business operating hours (at night or on weekends) could signal a compromised host.


Example of IPS alerts on non-working time (Holiday)

5) Network scans by internal hosts

Network scans by internal hosts communicating with multiple hosts in a short time frame, which could reveal an attacker moving laterally within the network. This incident detects from Perimeter network defenses such as firewall and IPS. You must choose Zone/Interface from “Internal” to “Internal” only. For Future, you should focus Reference: “Internal” to “DMZ” too. It may be “Insider Threat” or “Compromise hosts” that they need more information from your networks (Reconnaissance)


Example of Network Scans Report that filters from “Internal” to “Internal” zone

6) Multiple alarm events from a single host

Multiple alarm events from a single host or duplicate events across multiple machines in the same subnet over a 24-hour period, such as repeated authentication failures. THIS IS COMMON USE CASE.


Example Dashboard that monitoring “User Login Failures” from Single Hosts

Note: some login failed events form e-mail applications on mobile phones can generate events more 500 events/minute. I found this case when the password of a user account is expired but they have not change the new password on their devices.

7) System is reinfected with malware

After the Infected host is cleaned, a system is reinfected with malware within 5-10 minutes, repeated reinfections signal the presence of a rootkit or persistent compromise. This incident may detect from Endpoint Security Protection or Anti-Virus events.


This is Example Malware Dashboard.

Detection: You must create at least 3 rules on SIEM follow as

  1. The rule alert when it found infected host then “Add To” Current Infected Hosts List and Historical Infected Hosts List (Store at least 1 week)
  2. The rule alert when malware is cleaned from infected Host then “Remove To” Current Infected Hosts List
  3. The rule alert when it found an infected host that is “Historical Infected Hosts List” within the specified time range. THAT SYSTEMs SHOULD SCAN/INVESTIGATE MALWARE AGAIN!!!

8. Multiple Login from different regions

A user account trying to login to multiple resources within a few minutes from/to different region. This is a sign that user’s credentials have been stolen or that a user is up to mischief.


An example of the Correlated rule that Ideal solutions may vary based on your network conditions and security policy.

This rule detects an event in the “Login” normalization category, with an Event Outcome equal “Success” with multiple Source Geo-locations, within a specified Time Range and Events are grouped by Source User.

9. Internal hosts use much SMTP

E-Mail Protocol such as SMTP (Simple Mail Transfer Protocol), POP3 or IMAP4 should be monitoring. Some malware will use these port for send information to Suspicious or Hacker’s server.


Example of Infected client that use SMTP(TCP/25)

10. Internal hosts may query to External/Internal DNS

Many organization has Internal DNS servers for caching records and serve DNS service to internal hosts. DHCP configuration is defined Primary DNS Server to Internal DNS server. If you found that some internal hosts query to External DNS such as, (Google DNS), you should try scan malware on that clients.


Some Incidents found that the internal host query many requests to the internal DNS server (> 1,000 events/hour)

Action and Adaptation

Once the IoA is created, people and processes can act while the rich intelligence is distributed. Directly, alerts and thresholds can guide enforcement actions such as quarantine. In near real time, new findings can factor into policy adjustments, authentication requirements, and human response workflows. Within hours and days, findings can influence risk scores, organizational policies, and end-user education. Over longer timelines—weeks and months—organizations can trend and surface anomalies, predict future attacks and adjust sensitivities.

Red Team and Open-Source Mitre’s ATT&CK Framework Test Tools


One way to learn how to better defend your enterprise is to train a red team to simulate attacks. The Mitre ATT&CK framework, which can be a very useful collection of threat tactics and techniques for such a team. The frameworkclassifies and describes a wide range of attacks. To make it even more effective, various commercial and open-source general testing tools have been built to complement its schemas.

Adversarial Tactics, Techniques & Common Knowledge

MITRE’s Adversarial Tactics, Techniques, and Common Knowledge (ATT&CK™) is a curated knowledge base and model for cyber adversary behavior, reflecting the various phases of an adversary’s lifecycle and the platforms they are known to target. ATT&CK is useful for understanding security risk against known adversary behavior, for planning security improvements, and verifying defenses work as expected.

Video: Post-Exploit Threat Modeling with ATT&CK




Red Team Automation (RTA)

RTA provides a framework of scripts designed to allow blue teams to test their detection capabilities against malicious tradecraft, modeled after MITRE ATT&CK.

RTA is composed of python scripts that generate evidence of over 50 different ATT&CK tactics, as well as a compiled binary application that performs activities such as file timestopping, process injections, and beacon simulation as needed.

Where possible, RTA attempts to perform the actual malicious activity described. In other cases, the RTAs will emulate all or parts of the activity. For example, some lateral movement will by default target local host (though with parameters typically allow for multi-host testing). In other cases, executables such as cmd.exe or python.exe will be renamed to make it appeas as if a Windows binary is doing non-standard activities.




CALDERA is an automated adversary emulation system that performs post-compromise adversarial behavior within Windows Enterprise networks. It generates plans during operation using a planning system and a pre-configured adversary model based on the Adversarial Tactics, Techniques & Common Knowledge (ATT&CK™) project. These features allow CALDERA to dynamically operate over a set of systems using variable behavior, which better represents how human adversaries perform operations than systems that follow prescribed sequences of actions.



Atomic Red Team

Small and highly portable detection tests mapped to the Mitre ATT&CK Framework.

Our Atomic Red Team tests are small, highly portable detection tests mapped to the MITRE ATT&CK Framework. Each test is designed to map back to a particular tactic. We hope that this gives defenders a highly actionable way to immediately start testing their defenses against a broad spectrum of attacks.




Metta is an information security preparedness tool.

This project uses Redis/Celery, python, and vagrant with virtualbox to do adversarial simulation. This allows you to test (mostly) your host based instrumentation but may also allow you to test any network based detection and controls depending on how you set up your vagrants.





Invoke-Adversary – Simulating Adversary Operations

Invoke-Adversary is a PowerShell script that helps you to evaluate security products and monitoring solutions based on how well they detect advanced persistent threats. I was inspired to write this script after seeing APTSimulator excellent tool from Florian Roth.


Update 4/14/2018 – In the original script 3rd party tools were downloaded by the script automatically. I believe that the original disclaimers were enough, but decided to change it due to the feedback I got, and now the script ask the users to download the 3rd party tools by themselves – with additional warnings and hash file checking.

This script is provided AS IS without warranty of any kind.

The script should be used for authorized testing and/or educational purposes only with no exceptions. By using the script Windows system’s security and stability (including but not limited to: passwords dump, disabling security features, etc.) may be affected so DON’T RUN IT ON PRODUCTION systems.

The script is my own, based on other researchers’ public domain knowledge and not related to Microsoft in any form.


“Kill Chain”, or What happens during a targeted cybersecurity attack?

Cybersecurity kill chain is a framework developed by Lockheed Martin for identification and prevention of cyber intrusions activity. As attacks may occur in stages, you as defender can put optics and controls to detect or disrupt the entire process.

The stages of the Kill Chain are:

  • Reconnaissance – an attacker is probing for a weakness or bad configuration
  • Weaponization – an attacker is building a payload that can be delivered to the victim (can be a PDF  file or an Office document)
  • Delivery– Sending the payload via e-mail, web link or removable media
  • Exploit– The payload will execute on the victim’s network
  • Installation– The payload will download additional remote access tools and install them to maintain persistence
  • Command and Control– A channel is created between the victim and the attacker
  • Actions– The intended goal is executed (encrypt files, exfiltration of data, etc.)

On top of that model, Mitre, a not-for-profit organization, developed a enhanced model for cyber adversarial behavior, called “Adversarial Tactics, Techniques, and Common Knowledge” (ATT&CK™) Matrix.

Currently, the MITRE ATT&CK™ Matrix provides the most comprehensive framework for adversarial techniques and tactics that enterprises encounter daily.

Technique Description
Persistence Techniques for persistent presence on compromised system
Privilege Escalation Techniques for adversary to obtain a higher level of permissions
Defense Evasion Techniques adversary may use to evade detection or avoid other defenses
Credential Access Techniques resulting in access to or control over system, domain, or service credentials
Discovery Techniques that allow the adversary to gain knowledge about the system and internal network
Lateral Movement Techniques that enable an adversary to access and control remote systems on a network
Execution Techniques that result in execution of adversary-controlled code on a local or remote system
Collection Techniques used to identify and gather information
Exfiltration Techniques that result or aid in the adversary removing files and information from a target network
Command and Control Techniques that represents how adversaries communicate with systems under their control within a target network


Many companies are using Security Information and Event Management (SIEM), Endpoint Protection Platform (EPP) and Endpoint Detection & Response (EDR) products to monitor and protect their environments. What seems to be missing is a tool that can generate a real data that represents real-world targeted attacks.

Invoke-Adversary is a PowerShell script that uses a set of functions to simulate post-compromise adversarial behavior within Windows Enterprise networks.

By using Invoke-Adversary script you can:

  • Assess your security monitoring tools and practices
  • Evaluate Endpoint detection agents


Requirements for deploying:


  • The simplest way to run the script is to open an elevated (run as Administrator) PowerShell ISE window and press F5.

  • The script will start and the first thing you need to do is to read the disclaimer and accept the terms by typing yes


  • Now you can select any test case by choosing its number on the menu

  • Choose which test you want to run by choosing its number on the menu



What are the tactics

Defense Evasion

  • Disable network interface – Disables a network adapter and causes loss of network connectivity
  • Disable Windows Defender AV – Turn off real-time protection, scanning all downloaded files and attachments, behavior monitoring, network protection and privacy mode
  • Add local firewall rule exceptions – Add fictitious rule “Invoke-APT Test Rule” to Windows Advanced Firewall
  • Turn off Windows Firewall – Turn off Windows Advanced Firewall
  • Clear Security Log – clears the security log using wevtutil command

Persistence Tactics

  • Accessibility Features – “Hijack” sethc.exe with cmd.exe using “Image File Execution Options”
  • AppInit DLLs – Adds entry for pserver32.dll under AppInit_DLLs
  • Application Shimming – Create registry value under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{842562ef-8d28-411d-a67d-ab75ef611fe8}.sdb
  • Create local user – A new user (user name is: support_388945a0)
  • Create local Administrator – A new user created (user name is: Lost_337fde69_81a9) and added to local Administrators group
  • Create New Service – new service (WindowsHealth) is created
  • Create New Service (Unquoted Path) – same as previous, just with unquoted path
  • Registry Run Keys [HKLM] – New run key under HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\Run
  • Registry Run Keys [HKCU] – New run key under HKCU\Software\Microsoft\Windows\CurrentVersion\Run
  • Scheduled tasks – new scheduled task (OfficeUpdaterA) is created

How To Build And Run A SOC for Incident Response – A Collection Of Resources

How to build a SOC / How to run a SOC

In this resource I’ll locate some great resources for SOC, how to build a SOC, how to set-up a SOC and how to run and maintain your SOC once set up. I will also keep the links and tools up to date as I find new & better resources.

Let me know if you have comments or additions please.


1- Starting Point – Some theoretical content:

What is a SOC? A SOC is a Security operations centre‍, where you have people dedicated to the company’s ongoing information security watching and responding. They need the tools to prevent what they can and discover+remediate what they can not. They need the skills to do this.
