Today the German hacker group “The Hacker’s Choice” officially released a new DDoS tool. The tool exploits a weakness in SSL to kick a server off the Internet.

Technical details can be found at

“We decided to make the official release after realizing that this tool leaked to the public a couple of months ago” said a member of THC who wants to remain anonymous.

The tool departs from traditional DDoS tools: It does not require any bandwidth and just a single attack computer (“bot”).

“We are hoping that the fishy security in SSL does not go unnoticed. The industry should step in to fix the problem so that citizens are safe and secure again. SSL is using
an aging method of protecting private data which is complex, unnecessary and not fit for the 21st century.”, Says a THC member, referring to 3 major vulnerabilities disclosed in SSL over the past 3 years.

Backdoor Trojan alleged to have been created and used by German law enforcement authorities

Under German law, the police are allowed to use spyware to snoop on suspected criminals – but only under strict guidelines. The spyware must not alter any code on the suspect’s computer and safeguards must be put in place to prevent the Trojan being subverted to include additional functionality.

The Chaos Computer Club (CCC) has announced the discovery of a backdoor Trojan horse that is capable of spying on online activity such as recording Skype conversations and monitoring online behaviour. The CCC implies that the malware was created for, and is being used by, German law enforcement authorities such as the BKA and LKA.

Sophos’s analysis of the malware confirms that it has the following functionality:
* The Trojan can eavesdrop on several communication applications - including Skype, MSN Messenger and Yahoo Messenger
* The Trojan can log keystrokes in Firefox, Opera, Internet Explorer and SeaMonkey
* The Trojan can take JPEG screenshots of what appears on users' screens and record Skype audio calls
* The Trojan attempts to communicate with a remote website

“While it’s not possible to *prove* who authored the malware, it’s beginning to look more and more likely that the German authorities were involved,” said Graham Cluley, senior technology consultant at Sophos. “The malware targets Windows computers and to become infected, you typically might receive an email containing an attached file, or a link to the web which would then infect the computer. SophosLabs detects all malware that we know about – regardless of who the author might be. So whether this malware is state-sponsored or not, we’ve added protection against this attack.”

Facebook's URL scanner is vulnerable to cloaking attacks

Members of a hacking think-tank called Blackhat Academy claim that Facebook's URL scanning systems can be tricked into thinking malicious pages are clean by using simple content cloaking techniques.
Such attacks involve Web pages filtering out requests that come from specific clients and feeding them content that is different from what is displayed to regular users.
Attackers have been using this method to poison search results on Google for years now by serving keyword-filled pages to its indexing robot, but redirecting visitors to malware when they click on the links. However, it turns out that Facebook is also vulnerable to this type of content forging. "Hatter," one of the Blackhat Academy members, provided a live demonstration, which involved posting the URL to a JPEG file on a wall.
Facebook crawled the URL and added a thumbnail image to the wall post, however, clicking on its corresponding link actually redirected users to YouTube. This happened because the destination page was able to identify Facebook's original request and served a JPEG file.

"While most major sites that allow link submission are vulnerable to this method, sites including Websense, Google+ and Facebook make the requests easily identifiable," the Blackhat Academy hackers said.
"These sites send an initial request to the link in order to store a mirror thumbnail of the image, or a snapshot of the website being linked to. In doing so, many use a custom user agent, or have IP addresses that resolve to a consistent domain name," they explained.
Earlier this week, Facebook signed a partnership with Websense to use the security vendor's cloud-based, real-time Web scanner for malicious URL detection. Blackhat Academy has now provided proof-of-concept code, which, according to its advisory, can be used to bypass it.
Websense doesn't believe that to be the case. "This is nothing new. We use numerous methodologies and systems to ensure that our analysis of content (in real time) is not manipulated by malware authors, including using IP addresses not attributable to Websense so that malware authors are unaware that it is Websense analyzing the content," the company said.
"Also, the Websense ThreatSeeker Network is fed via an opt-in feedback loop from tens of thousands of customers distributed globally. These IPs are also not attributable to It is because of technologies like this that Facebook chose Websense to provide protection for their growing user base of more than 750 million users," it added.
That could well be true, but it's worth keeping in mind that Websense primarily sells security solutions to businesses and Facebook is usually blocked on many corporate networks. It would be logical to assume that relying on its customers' appliances to scan URLs on the social networking website might not have an immediate impact.
Hatter says that as a security research outfit Blackhat Academy follows responsible disclosure and notified Facebook of the content cloaking issue at the end of July. Despite this, the method still works.

"We're well aware of the content forgery technique described and have built protections into our systems to account for it," a Facebook spokesman said via email.
"The content returned when we crawl a shared link is only one of many signals we use to combat spam and abuse on Facebook. We know that this content can change between visits, and therefore can't always be trusted, and our systems account for that," he added.
Earlier this year, Facebook signed a partnership with Web of Trust (WOT), an organization that maintains a community-driven spam URL block list. However, it's well-known that blacklisting is not very efficient and there can be a significant window of exposure between the time when a URL starts being spammed and the time when it's flagged by such a system.
At the very least, content cloaking can be a powerful social engineering technique. A link with a .jpg termination accompanied by a thumbnail can look harmless enough to trick a lot of users into clicking on it.

Facebook and Websense are not the only ones with this problem. Google+ and Digg are also vulnerable to cloaking attacks, but other sites such as Twitter have developed strong protections against them.

WAVSEP - Web Application Vulnerability Scanner Evaluation Project

A vulnerable web application designed to help assessing the features, quality and accuracy of web application vulnerability scanners.
This evaluation platform contains a collection of unique vulnerable web pages that can be used to test the various properties of web application scanners.
Additional information can be found in the developer's blog:
Project WAVSEP currently includes the following test cases:

  • Reflected XSS: 66 test cases, implemented in 64 jsp pages (GET & POST)
  • Error Based SQL Injection: 80 test cases, implemented in 76 jsp pages (GET & POST )
  • Blind SQL Injection: 46 test cases, implemented in 44 jsp pages (GET & POST )
  • Time Based SQL Injection: 10 test cases, implemented in 10 jsp pages (GET & POST )
False Positives:
  • 7 different categories of false positive Reflected XSS vulnerabilities (GET & POST )
  • 10 different categories of false positive SQL Injection vulnerabilities (GET & POST)
Additional Features:
  • A simple web interface for accessing the vulnerable pages
  • Sample detection & exploitation payloads for each and every test case
  • Database connection pool support, ensuring the consistency of scanning results
Although some of the test cases are vulnerable to additional exposures, the purpose of each test case is to evaluate the detection accuracy of one type of exposure, and thus, “out of scope” exposures should be ignored when evaluating the accuracy of vulnerability scanners.

Arachni v0.3 is out!

Arachni - a dramatic improvement in the detection accuracy of Reflected XSS exposures, and a dramatic improvement in the detection accuracy of SQL Injection exposures (verified on mysql).

Arachni uses various techniques to compensate for the widely heterogeneous environment of web applications.
This includes a combination of widely deployed techniques (taint-analysis, fuzzing, differential analysis, timing/delay attacks) along with novel technologies (rDiff analysis, modular meta-analysis) developed specifically for the framework.
This allows the system to make highly informed decisions using a variety of different inputs; a process which diminishes false positives and even uses them to provide human-like insights into the inner workings of web applications.

Version v0.3 has just been released and it includes a lot of goodies including:
  • A new custom-written, lightweight Spider
  • Add-on support for the WebUI
    • Scan scheduler
    • AutoDeploy -- Convert any SSH enabled Linux box into a Dispatcher
  • Improved accuracy of differential analysis audits
  • Improved accuracy of timing attack audits
  • Highly optimized timing attacks

HITB SecConf2011 Malaysia (October 10 to 13)

Run as a not for profit, community backed effort, the Hack in The Box Security Conference (HITBSecConf) series has become the ‘must attend’ event in the calendars of security professionals from around the world.
Having started as a small gathering of Malaysian security specialists in 2002, the event has since expanded out of its home base in Kuala Lumpur to Dubai and in 2010, The Netherlands. Our events are put together by a team of dedicated crew and volunteers and through the continued support of our sponsors, HITBSecConf has grown into the largest network security conference in the Asia Pacific and Middle East region!
The main aim of our conferences has always been to enable the dissemination, discussion and sharing of deep knowledge network security information. Our main focus is on new and groundbreaking attack and defense methods that have not been seen or discussed in public before. HITBSecConf events bring together a unique mix of security professionals, researchers, law enforcement and members of the hacker underground under one roof and our flagship event in Malaysia sees over 1000 attendees.
The event runs over a 4 day period with 2 days of intensive hands on training sessions followed by a two-day conference with either three or four concurrent tracks inclusive of a hands on lab session (HITB Labs) and 15 minute lightning talks (HITB SIGINT). The HITB Labs caters for only 50-100 attendees and these sessions are intensive, hands-on presentations that require audience interaction. The HITB SIGINT (Signal Intelligence/Interrupt) sessions on the other hand, are designed to provide a quick 15 minute overview for material and research that's 'up and coming' - stuff that isn't quite ready for the mainstream tracks of the conference but deserve a mention nonetheless.
In addition to the conference tracks, our events are also further enhanced with an open-to-public technology and exhibition area, lock picking villages, hackerspace villages and of course, our ever popular Capture The Flag competition (CTF) !
