The Demystifying Tech Podcast invited me back as a guest, and during the conversation the security of elections was discussed. It was given only a few minutes between other items which is a real shame, so I thought I’d expand on some of the points I made here and give a little bit of an introduction to the prior art of election hacking.
This week I was asked some specific questions about the security of iframes. The questions came about from a PCI standpoint, for stores that use fully outsourced iframes for taking payment.
Short answer: The attacks are very limited.
Following a successful penetration test, you may have large amounts of data to exfiltrate from an environment specifically hardened to make it difficult to exfiltrate data. For example, the network might have a firewall that explicitly blocks common exfiltration methods – such as SSH, HTTPS, HTTP.
It is common that you can still exfiltrate data from these networks by using DNS. For example you could make a request to a domain name that you control where the subdomain contains some information to be exfiltrated. Such as sensitive-data-here.attacker.example.com. DNS is a recursive system, such that if you send this request to a local DNS server, it will forward it on and on until it reaches the authoritative server. If you control the authoritative server, you can simply read the sensitive data from the DNS logs.
There is a case ongoing which is known as The United States versus Love. As always when I mention the law on this site, I am not a Lawyer, therefore I will link to all of my sources inline and allow you to draw your own conclusions. I support Lauri Love and I would like to detail some reasons as to why you should too. I also wish to highlight some things you should be seriously concerned amount regardless of your opinion on Lauri or his case specifically.
My pinned tweet got a lot of attention online, in fact it’s got more attention than probably ever one of my other tweets combined – even more than that time I had a Rap Battle over twitter! Tweets are short, you’re limited to 140 characters and it’s difficult to give depth and context in such a small message.
