SNMP: Part 1 SNMP Client in C and Introduction

•March 6, 2015 • Leave a Comment

SNMP Client written in C, started up and ready to fire!:

In this first of a two post article will cover:
-Basics of SNMP.
-Writing an SNMP Client in C.
-The usefulness it can have in conducting penetration testing and hacking.
In Part 2 I will cover
-Possible malicious use of SNMP, that could be performed by an attacker, and how this could be mitigated.

As a note, all of this is performed on a windows 7 system with Visual Studio 2013 as my IDE.

The SNMP protocol is used for communicating with network devices.

Typical queries in SNMP are things such as: bytes In/Out on an interface, errors, CPU load, Uptime, and temperature.
SNMP requests are performed through a numbering scheme where each perion (.) represents a leg of the MIB tree pictured below. The numbers represent the member of that MIB tree leg extention:



As pictured above it is easy to see that an SNMP request such as a GET or a SET request with the data of represents the SysDescr member.
Or expanded, it represents: iso->org->dod->Internet->directory->mib-2->SysDescr.

SNMP is generally defined under the following RFC’s, and is carried out under UDP communication and on port 161 and 162.

Version 1 was originally written in 1988.
Version 1:RFC1155, RFC1156, RFC1157
Version 2:RFC1901, RFC1908, RFC2578
These updates Extended version 1, added new data types, and added better retrieval methods such as GETBULK.
version 3:RFC3411, RFC3418 (w/security)

Typically SNMPv2 (v2c) is used.

Basic commands in SNMP are:
GET (client to server), Query for a value.
GET-NEXT (client -> server), Get next value (list of values for a table)
GET-RESPONSE (server to client), Response to GET/SET, or error.
SET (client to server), Set a value, or perform action.
TRAP (server to client), Spontaneous notification from equipment (line down,temperature above threshold, etc).

Community strings act to only allow “authorized” requests.
The common (and misfortune) practice of leaving things default leads to the widespread use of the two default community names, although others exists, and can be used to find some really interesting equipment.
The two default (or one of the 3 variations used for each “public” and “private”) common community strings are “public”, “Public”, “PUBLIC” and “private”, “Private”, “PRIVATE”.
Public is for read-only access to the device.
Private is used for write access to the device..

Below is a GET request in Wireshare and the subsequent server response:


Wireshark response to GET request:
snmp-packet received

Version 1, originally conceived in the 80’s. Community strings are sent in plain text.
Version 2c: SNMP v2c was developed to fix some of the problems in v1. Community strings are still sent in plain-text.
Version 3: The newest version of SNMP, v3 supports full security and authentication.

Refer to the RFCs quoted above for more information.



Below is some source code that performs a query with a GET-NEXT request, and subsequently walks the table by successively requesting the OID string returned in each request, starting with “1.3”.
The compiled Executable and accompanying project file is also downloadable.

Rhys A. Mossom Network Security Services has been formed to offer Cyber Security offerings to South Africa, Southern Africa and on a wider international scale.

Rhys A. Mossom Network Security Services is based in Johannesburg, South Africa delivering international services, specializing in ethical hacking, penetration testing, web-application testing, vulnerability assessments, and information-security compliance assessments.

R.A.M Network Security Services encompasses a broad range of security-testing methods known as Ethical Hacking. It is the practice of assessing the security posture of a given security system, using the same tools and techniques employed by blackhat-hackers on a daily basis. These techniques can be performed against system Operating Systems, services, software and website-applications. There are a number of ways to achieve various results, according to your business needs.

The benefits of a comprehensive analysis can range from reducing the likely hood of downtime and financial or other business implications and damage to electronic assets.

According to the currently available statistics at the time of writing, the document “Net Losses: Estimating the Global Cost of Cybercrime Economic impact of cybercrime II Center for Strategic and international Studies – June 2014” by the renowned global Security company, McAffee, estimates that 0.14% of South Africa’s GPD is lost through cyber-crime. This equates to just less than five (R4.91 Billion) Billion Rand that is stolen. Additionally South Africa ranks number six amongst the most targeted counties for cyber-crime globally by the U.S. Federal Bureau of Investigation (FBI), whilst another renowned security company, Symantec, listed South Africa as the third worst hit country globally by cyber-crime.

[ Game Trainer ] Assassins Creed 4 – Black Flag Stealth/Invisibilitity hack

•September 29, 2014 • 3 Comments


Here is a basic trainer for Assassins Creed 4 – Black Sails.
The game, although fun, is full of annoying sneaking missions. This trainer can assist here.
By searching for a specific array of bytes that represent a compare and a jump and replacing them with no-operation commands a sort of invisibility hack is created. By searching for an array of bytes and not relying on fixed addresses it is possible for this trainer to work on multiple versions, if not all versions.

The array of bytes to search for is: 0x80, 0x7d, 0xff, 0x00, 0x74, 0x0a, 0x5e

This should be replaced with six NOP’s.
The Address in my version of the game is 0x018a239b

Image of memory before patching:


Image of memory after patching:


I have attached source code to automatically patch it.

The trainer is designed as a launcher, and as such must be placed within the games root directory and then executed. The trainer will then launch Assassins creed, whilst searching for the relevant arrays to patch. The hack is completed once a call to WriteProcessMemory is made and six NOP’s are written to the address determined through pattern-searching.

Image of the trainer/launcher is displayed below:

[ Security Tool ] Orafuzz Version 2 – HTTP Fuzzing Tool

•April 29, 2014 • Leave a Comment


This application is a rewrite of my original fuzzer. Several features have been added as well as a full user-friendly GUI.

Additionally the major change in this version is the ability to modify and add the attack strings through the provided sample list. This adds to the overall flexibility of the application.

Additionally the application now supports both POST and GET requests.
The provided text file “attackstrings.txt” contains a list of attack request strings, this file must reside in the applications root directory.

This can also be used to determine whether vulnerability “CVE-2007-1036 JBoss JMX-Console Access Vulnerability” exists on a particular server.

You can try for yourself a target with google, and a google dork: inurl: /reports/rwservlet/help?

As mentioned the contents can be modified to suit the attackers needs.
The sample contents of the “attackstrings.txt” file are as below:
