DIY Exploits Embedding Tools - a Retrospective

Great analysis by the Spywareguide folks -- Chris Boyd and Peter Jayaraj in this assessment -- especially my deja vu moment with the King's IE Exploiter tool which I intented to cover in an upcoming post, in a combination with a brief retrospective of exploit and malware embedding tools that were empowering entire generations of script kiddies during the last couple of years. These tools are a great example of what the DIY trend used to look like before malicious economies of scale were embraced in the form of today's modular and efficiency-centered malware kits we're aware of.


-- The IE Exploiter v1.0/2.0

The tool is first know to have emerged back in 2002, with its latest version released in 2004. It was first branded as the "Fearless IE Exploiter" and then returned back to it's original name. Description of the v1.0 : "Fearless IE Exploiter allows you to embed executable files into HTML documents, that when viewed in an unpatched version of Internet Explorer 5.* will automatically download and execute the .exe". And the description of v2.0 : "IE Exploiter v2 is a very simple tool that creates a HTML file with an embedded executable file. Once the HTML file is viewed the executable file will overwrite notepad.exe on the target system and then execute it using the view-source: prefix."

-- King's IE Exploiter

King's IE Exploiter is an Arabic DIY exploit embedding tool released around 2004. Despite that the malware embedded sites generated on-the-fly come totally unobfuscated, we will yet wait and see the eventual release of such feature.

-- Zephyrus

Again relased around 2004, the description reads : "Its a prove of concept tool to generate a Stench MediaPlayer Exploit file more infos about stench can be found here http://malware.com or at here AVP calls it exploit.win32.zephyrus"

Result: 30/32 (93.75%)

-- God's Will

The description reads : "A GODMESSAGE page is an HTML page that works with an ACTIVEX bug founded in IE5.5/OUTLOOK/OUTLOOK EXPRESS. Thanks to this bug when someone view our godmessaged page he downloads an HTA file in his STARTUP FOLDER.'

Result: 32/32 (100%)

-- Ed Html Infector

The description of the tool circa 2004 reads : "Ed HTML Infector is a very simple tool that creates HTML file with an embedded executable file within."
