Ok in this scenario we care going assume SQL login credentials (sqluser) are exposed and that firewall rules are wide (so we have layer 3 connectivity to the target).
We have loaded Metasploit and will be using the msssql_enum modue
Now that we have configured our target options we can run the module:

Covenant is a .NET c2 (Command & Control) Framework that aims to highlight the attack surface of .NET and aid red teamers! Today I’m going to jump into slip space with a Halo themed blog on my first use of Covenant in the lab. Let’s hope I don’t need Cortana to get this deployed (yes I’m a massive Halo nerd!)
First thing let’s head over to GitHub and check out the install notes:
The architecture seems to look like this:

I was on Twitter the other day (when am I not? 😉) and a post caught me eye, an industry friend’s post caught my eye, challenging the audience to identify their location (specifically which station they are at!), this I thought might be a cool challenge. The first post below is from Paul (Gaming Works) which gives a limited amount of information and a nice image:

Well with the year winding down you’ve probably seen that Microsoft just released an out of band security patch:
https://portal.msrc.microsoft.com/en-us/security-guidance/advisory/CVE-2018-8653
CVE-2018-8653 is described as:
“A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Internet Explorer and then convince a user to view the website, for example, by sending an email.”

Ok, so I ordered a Kensington VeriMark fingerprint reader to see how for a few British pounds (or whatever currency you use!) you can add fingerprint authentication to a Windows desktop in minutes!
So this is being conducted with 0 reading of docs (because it’s fun to research just how simple you can a) enable security or b) mess things up when you don’t RTFM!. The next step on my uncharted journey, I plugged in the device to a spare USB port and didn’t see a failed driver installation toast, so we are looking good (note the sensor is the largest rectangle surface on the device, not the one with a cool blue LED)
Now I hit the windows key and typed finger and Win10 prompted me for the settings pane (that was lucky!) Read more “Using Windows Hello to enable fingerprint authentication”
Hacking
Following on in the series from my previous post – My OSCP Diary – Week 1 I continue my offensive security professional certification journey!
So, after a break in my training schedule (pro tip, ask Offensive Security (Offsec) to pause your PWK lab time – I didn’t which was stupid) I’m back into the PWK labs!
The first thing I realised after having ~ 40 days break was taking that long a gap isn’t the best idea (but hey holidays and life have to happen right!) I got back into the lab and looked at my attack Visio blankly for a bit, realising the task ahead of me had a lot of servers still in it!
I think the first box I decided to hit was pain, as its name says this box is not easy as is considered an OSCP boss box, as its name says, it’s painful but quite fun once you have cracked it. Read more “OSCP Week 2”

Yesterday I published a quick blog which looked at what we could do an out of the box Windows server to monitor file integrity and audit/alert upon actions such as modify or deletes. This is however rather clunks and not really for business use, so next stop the open source world! Today we are going to look at OSSEC! Now before some people go mad about security and open source…. OSSEC is used in Alien Vault’s solution, is compliant with PCI and is used worldwide by loads of organisations and universities etc. Open source tools and security go hand in hand, stop with your crazy talk! Now we’ve got that rant over with let’s get onto the fun business!
OSSEC is an open source host intrusion detection solution which we can use to upgrade our auditing and alerting solution to be more feature rich and provide a centralised solution, for more info on OSSEC please visit their website – https://www.ossec.net/ Read more “Upgrading our file integrity monitoring solution using open source technologies – Part 1”

In the wake the of the British Airways breach I thought I would shed some light on a technique to help detect and alert (help respond) to events that may affect critical business processes by modifying critical or sensitive files. We are going to start with a simple scenario using out of the box tools.
Windows Server comes with a number of security features including object access auditing, in this post we are going to take a brief look at enabling monitoring of sensitive data files. The example we are going to use are monitoring for changed to the web.config file used my .net web applications.
To start with in our example machine, we are going to need to enable audit object access either using local policy or preferably group policy (it should be noted you need to think about log volume, collection and retention/rotation).

Breach
As reported across major news networks over the world, British Airways has suffered a data breach that not only includes customer data but also includes payment details. Details from 380,000 customers have been accessed by an unauthorised third party. More details can be found on news sites such as:
https://www.theregister.co.uk/2018/09/06/british_airways_hacked/
https://www.bbc.com/news/uk-england-london-45440850
It’s likely that attackers have compromised a web service which is linked to payment services, however no specific details have been released yet so until then we can only speculate.
In this post we look at the information reported by British Airways, guidance for customers from BA, ourselves and NCSC but also we discuss the steps business’s should be taking to ensure they have a strong security posture, especially where customer data is concerned.

I’ve been working on the technology industry for the last 17 years, planning, designing, building and operating solutions since I was able to access the internet. I’ve been working the last 10 years as a consultant architect (across a number of domains) working with clients to understand their businesses, their technology needs, current deployments, gaps, road map and create solutions to enable their businesses, but you can’t do that if you introduce risks to businesses by creating unnecessary and unwanted security risks.
I’ve delivered services directly for and as part of a supply chain for a large range of organisation verticals from global media organisations, logistic firms, retail, telecommunications, media & entertainment through to local authorities, central government agencies, armed forces and the metropolitan police.
