Bypassing Content Security Policy with a JS/GIF Polyglot (old 2015)
This post explains the creation of a JS/GIF polyglot to bypass Content Security Policy (CSP) in certain scenarios. We will build a custom polyglot file that is a valid GIF as well as JavaScript and use Xenotix to simulate real world exploitation.

Your PoC JS code can be just "alert(0)" or for Red Team Pentesting I would suggest you to use OWASP Xenotix XSS Exploit Framework (as I wrote it) or Beef (an alternative). In this post i will be using Xenotix.

Download Latest Xenotix from http://xenotix.in

Chrome browser: Security implications of "--allow-file-access-from-files" - Stack Overflow
Ok, so you're saying that, by default, an HTML document opened in the browser, originating from the local file-system, cannot subsequently refer to another local file. Permitting this means potentially a maliciously crafted HTML + JS page dropped somewhere in your filesystem, when opened in a local browser, could submit the contents of a sensitive local file to an external entity. – Geeb Apr 2 '15 at 13:02

Yes, that sums it up nicely. – SilverlightFox Apr 2 '15 at 13:04

British Airways: suspect code that hacked fliers 'found' • BBC News
<p>A RiskIQ researcher analysed code from BA's website and app around the time when the breach began, in late August.

He claimed to have discovered evidence of a "skimming" script designed to steal financial data from online payment forms.
BA said it was unable to comment.

A very similar attack, by a group dubbed Magecart, affected the Ticketmaster website recently, which RiskIQ said it also analysed in depth.

The company said the code found on the BA site was very similar, but appeared to have been modified to suit the way the airline's site had been designed.

"This particular skimmer is very much attuned to how British Airway's payment page is set up, which tells us that the attackers carefully considered how to target this site instead of blindly injecting the regular Magecart skimmer," the researcher <a href="https://www.riskiq.com/blog/labs/magecart-british-airways-breach/">wrote in a report on the findings</a>.

"The infrastructure used in this attack was set up with British Airways in mind and purposely targeted scripts that would blend in with normal payment processing to avoid detection."
Hacks like this make use of an increasingly common phenomenon, in which large websites embed multiple pieces of code from other sources or third-party suppliers.</p>

The RiskIQ report (linked above) is well worth reading, and quite scary: this is a professional group dubbed "Magecart" that has been operating for the past three years and pulling off increasingly subtle hacks. This one injected Javascript code into BA's system. RiskIQ says it sees similar attacks every day; just not as big.

Who Left Open The Cookie Jar?
Complexity of the attack surface makes for exploitable bugs.
Good reading of what kinds of things can happen.
