Caution – Rant within

Cyber

Well the press have gone mad for “Cyber” now. Everywhere is awash with news on massive Cyber attacks being conducted against the UK’s infrastructure and enterprise, but it leaves a burning question in my head; Why are all these systems susceptible to attack? If these systems are that important, air gap that shit. Don’t have it connected to the public Internet in the first place.

Building a Secure Server from Default Ubuntu

October 28th, 2011 by peter.bassill

I have been asked on a few occasions if I would put together an outline on how to build a secure server from scratch. Having thought the topic through on a number of occasions and having tried to write this blog article on what is probably nearer 20 times I finally bit the bullet and got on with it.

In this post, I will explore how to take a default Ubuntu install, in this case it is 11.04 server, and build it as a secure web server.

Ham? No, this is Spam

October 23rd, 2011 by peter.bassill

Every day I log into my  email server and that spam folder mail count has increased. This morning was not different, although when I logged in the email server today and I had spam in my inbox. Started me thinking is Spamassassin had died, it had! So I thought I would post this with comments on why this is very much wrong.

Mobile Phone Woes

September 12th, 2011 by peter.bassill

It is a crap way to start the week, finding your car has been broken into on a Monday morning. But its not all bad, im still here….

So the freaks, who if I got my own way would now be part of the garages ring main, gained access to my car and releaved me of iPhone (it was an original dammit! and loaded with tracking software, I know where you are right now scum bags!), iPod (hope you enjoy the ISD Podcast) and my Google Nexus II (killed thanks to Kaspersky).

Props to the local police though, forensics on scene is less time than it took for me to look up the new non-emergency phone number and our local neighborhood policeman less that an hour later to follow up and take a statement. Excellent service by the police.

Godaddy? Gofigure

September 7th, 2011 by peter.bassill

In a moment of madness for which I must apologize, I decided it would get a great idea to get an EV certificate for my site. I can almost hear the people falling of their chairs, but serious how hard could it be. Well, here is how hard:

Lets use GoDaddy. Why? The process seems simple and I have some domain names with them so why not also switch to DNSSec while I am at it. Good idea so far? I thought so.

GoDaddy’s EV process: Fix the following:

Dear Secure Certificate Customer,

Thank you for your recent extended validation certificate request. We will need additional information to verify your request.

Phone Bill
We were unable to find a listing for the phone number on your application with your exact company name using the online verification sources that are approved by our auditors. In order to proceed with your Secure Certificate application we will need you to provide us a verifiable phone bill that shows the phone number on your application.  The bill will need to be in your company’s name, show the address listed on your application, and cannot be older than 6 months. You can send this documentation through either fax or email.

Whois Update
The domain is registered to a different company name then the company requesting the certificate. We need to verify the requesting company has sole ownership to this domain. The easiest way of confirming this information is to update the whois registrant to be “Hedgehog Security Ltd”. Please make this update. When this is complete or if this can not be completed, please contact us.

HR Contact
Part of our verification process requires us to confirm the name, title, and agency of the approver/signer contact(s) in the application by contacting a member or person who acts as an HR representative of the company.  The HR representative cannot also be the requestor, approver, or signer.  Please provide us the name of an HR representative, we can contact at the phone number for your company, to validate the approver/signer’s title in the application.

Let me know if I can be of further service.

Step 1 – Well, try searching the UK and not the USA or Canada. Now, I dont know about anywhere else, by BT do NOT list the businesses phone number on the bill. They do however list the company name, account number and reference, but not the phone number.

Step 2 – Have the customer get their WHOIS details correct. Ok, simple enough and a fair enough comment. It was a little out that the chance could be perceived to be picky but ok, lets make it very accurate.

Step 3 – Do what? HR contact? Blimey….. Ok, ill use my accounts, that will be fine.

So, we fix a few items such as the company name on the phone bill and submit.

Hello Peter,

Thank you for sending the phone bill. Unfortunately we will not be able to use the phone bill provided because it is not in the Companies name. Please see the requirements below and send an updated phone bill.

In order to proceed with your Secure Certificate application we will need you to provide us a verifiable phone bill that shows the phone number on your application.  The bill will need to be in your company’s name, show the address listed on your application, and cannot be older than 6 months.  

Let me know if I can be of further service.

Yes it is. It is clearly in the Companies name, it is listed there just above the address……

So I contacted GoDaddy and it appears that unless I can have BT put the business phone number of the bill then no dice. Ok, how about a refund then? Oh, you cant because you gave me free products?

 

Godaddy? Go fail at providing services people paid for by asking for documents that simply dont exist.

Seems I am joining the mass of customers leaving then.

Digital Forensics – Project Ebay

September 2nd, 2011 by peter.bassill

Update 2

I now have processed 20 drives from a reasonable spread of reclamation businesses and private individuals and thus far only three drives have failed to give up the previous owners information. That is a good return for me, and a very poor display for information security practises. The home users I am not too surprised with, but still the corporates are getting this wrong. I am certain that the business entities engaging these reclamation organizations who are reselling this equipment on ebay would be shocked that in many cases the drives were just formatted.

Of course, all of these drives have now undergone a DoD 7 pass wipe to make sure they are completely erased, but the top 5 data sets recovered are:

  1. Email
  2. Corporate documents
  3. iTunes collections
  4. Personal photo’s
  5. Personal Identifiable Information

 

 

Compliance != Security

Compliance does not equal security.

Digital Forensics – Project Ebay

July 17th, 2011 by peter.bassill

Update 1

Project Ebay is moving along very nicely. To date 10 drives have been purchased across a reasonable spread of reclamation businesses and private individuals and thus far each and every drive has given up the previous owners information. That is a 100% success rate at recovering previous owners data.

Of course, all of these drives have now undergone a DoD 7 pass wipe to make sure they are completely erased, but I have pulled back:

  • Email
  • Banking records
  • iTunes collections
  • Personal photo’s
  • Very very personal photos
  • University assignments
  • Source code
  • CAD images

The home users I am not too surprised with, but the corporates? I am certain that the business entities engaging these reclamation organizations would be shocked that in many cases the drives were just formatted, and in one case the all I needed to do was hook the drive up and mount it.

 

Digital Forensics – Project Ebay

May 7th, 2011 by peter.bassill

Sometimes you just need to keep the forensics skilled honed. This series of posts will be around a number of drives obtained from ebay.

Imaging

Using an ubuntu 11.04 system with a pair of 1TB drivers as a base, we issue the following command to image the first drive:

dcfldd if=/dev/sdb conv=noerror,sync hashwindow=1M hash=md5 hashconv=after hashlog=/opt/forensics/hashlog.log split=640M splitformat=aa of=/opt/forensics/image.dd
