Illegal File Sharers To Be Cut Off By 2011

The New Acunetix V12 Engine


It was 2008 when the UK government originally proposed disconnecting pirates from the Internet, then a few months later Australia followed suit.

The latest is that it’s really going to be legislated and will come into force by April 2010 under the Digital Economy Bill.

I’ve noticed this trend picking up lately, a few companies are adopting this strategy or at least discussing it. First hit – warning, second hit – suspension then finally third hit is permanent disconnection and possible blacklisting.

Illegal file-sharers could be booted off the internet by summer 2011, says Lord Mandelson. The Business Secretary, who has been charged with ironing out the UK’s plans to tackle internet piracy, revealed that disconnecting repeat offenders will be a last resort.

Mandelson told the government’s Digital Creative Industries Conference that the “consequence-free” days of illegal file-sharing are over, and that a “legislate and enforce” strategy had been identified as the best way to tackle the problem. “Three strikes is a reasonable way of describing our approach,” he said.

The legislation, which will see those caught illegally downloading sent warning letters, will be officially set out in the Digital Economy Bill that is expected next month and will come into force in April 2010. “Technical measures will be a last resort and I have no expectation of mass suspensions resulting.”

I don’t see what the big deal is really, just use encrypted protocols or sign up to a VPN package and use another country that’s no so big on stamping down on piracy.

A lot of people use VPNs here in US or UK simply because BitTorrent traffic is throttled, it’s a small price to pay.

The same measures could be used to avoid any ISP snooping and get your downloads in peace. The whole Torrent scene has become a bit of a mess lately and it’s a hotpot of bogus files and tracked downloads.

Even with something like PeerGuardian you aren’t totally safe.

Repeat offenders will be issued with a second letter. If this fails to stop them illegally downloading, they will be put on a “serious infringers list”, with ISPs expected to “exercise technical measures”.

Mandelson also said that Ofcom will monitor the success of the warning letters in the first year and if illegal file-sharing has not reduced by 70 percent then suspending net connections will be brought into force.

“The threat for persistent individuals is, and has to be, real, or no effective deterrent to breaking the law will be in place,” he added.

Mandelson also said a “proper route of appeal” would be available for those suspended from the web. Once notified of possible suspension, offenders will be given 20 working days to appeal to an independent body, although Ofcom has yet to appoint the body. Mandelson said the suspension would not come into force until the appeal has been heard.

It’s interesting as well that they aren’t going hardcore right off the bat, they are still giving people a chance. If piracy reduces by 70% after the initial measures are put in place no-one will get disconnected.

Does that mean 30% of people can still download copyright content without any repercussions?

I’ll be watching the implementation anyway to see what kind of effect it has, I’d like to see the figures before and after 12 months and of course the metrics for measurement.

KrbGuess – Guess/Enumerate Kerberos User Accounts

Use Netsparker


KrbGuess is a small and simple tool which can be used during security testing to guess valid usernames against a Kerberos environment. It allows you to do this by studying the response from a TGT request to the KDC server. The tool works against both Microsoft Active Directory, MIT and Heimdal Kerberos implementations. In addition it will detect if an account lacks pre-authentication.

The tool is supplied with a file containing a list of usernames and requests a TGT for each user and then waits for the response. If the KDC responds with a valid TGT or with an error message stating that pre-authentication is required, a valid username has been discovered. Several guesses can be run in parallel (currently only against a single KDC) in order to improve performance.


Be careful not to run with to many threads and low timeouts as it will bring the KDC to its knees during the time of the test. The default values have been tuned against a virtual machine, and currently eat somewhere around 80% CPU which gives me roughly 700 guesses per second. In most cases the network throughput won’t be the performance bottleneck. So far I’m seeing that 2-3MBit of queries is generating a sustained 100% CPU load against both Heimdal on Ubuntu and Windows 2003.

The tool is written in Java and does not rely on any Kerberos libraries to perform the guessing. In order to successfully run the tool against a system it needs at least the realm, dictionary and a server parameters to be set. eg.

Facebook E-mail Spam Conceals Malware Attack

Use Netsparker


Facebook has had a fair share of problems, being a large community of course it’s going to be a ripe target for spammers, scammers and malware distributors.

The latest to hit is a spam e-mail claiming to be from the Facebook team that actually spreads a nasty piece of malware called Bredolab. It’s also been observed the trojan will connect to additional servers to install more malware.

The ultimate goal as usual is to make the victims part of a botnet.

Researchers at several security firms have uncovered a spam campaign targeting Facebook users. The e-mails, which pose as communications from Facebook about password resets, contain a nasty downloader that ultimately makes users part of a notorious botnet.

Researchers at several security firms have tied the Bredolab Trojan to a spam campaign targeting Facebook users.

The malware is being blasted out by spammers in e-mails claiming to come from “The Facebook Team.” Inside the e-mails is a message that the recipient’s Facebook password has been changed. In order to get the new one, recipients are told to open the accompanying attachment containing the malware.

Researchers at Websense told eWEEK Oct. 27 that they have observed more than 350,000 of the messages. On the company’s blog, researchers explained that the malware connects to two servers to download additional malicious files. Among them is Pushdo, also known as Cutwail.

This spam campaign seems to be generating some fairly high levels of traffic meaning whoever is behind it is pretty serious and committed to this vector for disseminating malware.

Social engineering isn’t a new method for propagating malware as always the weakest link is never the technological barriers but is always the stupidity/greed/gullibility of humans.

You can ALWAYS hack the wetware.

“One of the first things we saw this Trojan horse download was the Pushdo bot which began spamming out more of these Facebook password reset emails,” according to M86 Security.

MX Logic noted that Bredolab bypasses firewalls by injecting its own code into the legitimate process svchost.exe and explorer.exe. It also contains anti-sandbox code to thwart researchers, and creates the following files: %AppData%\wiaservg.log, %Windir%\temp\wpv861256600826.exe and %Programs%\Startup\isqsys32.exe. Bredolab also creates the processes isqsys32.exe and svchost.exe.

Sophos is detecting the malware as Troj/BredoZp-M or Mal/Bredo-A.

“Don’t make life easy for the hackers hell-bent on infecting your computer, stealing your identity and emptying your bank account – exercise caution when you receive unsolicited emails and protect your computer with up-to-date security software,” Graham Cluley, senior technology consultant at Sophos, advised in a blog post.

It looks like a pretty advanced piece of malware code which evades firewall measures and even tries to thwart analysis by AV companies.

Anti sandbox code and process injection, these bad guys are getting smart.

That does not bode well for the average citizen.

Yokoso! – Web Infrastructure Fingerprinting & Delivery Tool

Use Netsparker


Yokoso! is a project focused on creating fingerprinting code that is deliverable through some form of client attack. This can be used during penetration tests that combine network and web applications. One of the most common questions we hear is “so what can you do with XSS?” and we hope that Yokoso! answers that question.

We will creating JavaScript and Flash objects that are able to be delivered via XSS attacks. These code payloads will contain the fingerprinting information used to map out a network and the devices and software it contains.

In basic terms Yokoso! is a collection of infrastructure fingerprints. These fingerprints are useful during penetration tests to determine both what infrastructure is in use and to determine who are the admins of that infrastructure. It is built using the URIs of the web administration interfaces.

You can download Yokoso! v0.1 here:

Web Application Security Consortium (WASC) 2008 Statistics Published

The New Acunetix V12 Engine


The Web Application Security Consortium (WASC) is pleased to announce the WASC Web Application Security Statistics Project 2008. This initiative is a collaborative industry wide effort to pool together sanitized website vulnerability data and to gain a better understanding about the web application vulnerability landscape. We ascertain which classes of attacks are the most prevalent regardless of the methodology used to identify them. Industry statistics such as those compiled by Mitre CVE project provide valuable insight into the types of vulnerabilities discovered in open source and commercial applications, this project tries to be the equivalent for custom web applications.

Goals

  1. Identify the prevalence and probability of different vulnerability classes.
  2. Compare testing methodologies against what types of vulnerabilities they are likely to identify.

The statistics was compiled from web application security assessment projects which were made by the following companies in 2008 (in alphabetic order):

  • Blueinfy
  • Cenzic with Hailstorm
  • DNS with WebInspect
  • Encription Limited
  • HP Application Security Center with WebInspect
  • Positive Technologies with MaxPatrol
  • Veracode with Veracode Security Review
  • WhiteHat Security with WhiteHat Sentinel

The statistics includes data about 12186 sites with 97554 detected vulnerabilities. The report contains Web application vulnerability statistics which was collected during penetration testing, security audits and other activities made by companies which were members of WASC in 2008. The statistics includes data about 12186 sites with 97554 detected vulnerabilities.

Nikto 2.1.0 Released – Web Server Security Scanning Tool

The New Acunetix V12 Engine


It’s been almost 2 years since the last update on Nikto, which was version 2.

For those that don’t know, Nikto is an Open Source (GPL) web server scanner which performs comprehensive tests against web servers for multiple items, including over 3500 potentially dangerous files/CGIs, versions on over 900 servers, and version specific problems on over 250 servers. Scan items and plugins are frequently updated and can be automatically updated (if desired).

Nikto is not designed as an overly stealthy tool. It will test a web server in the shortest timespan possible, and it’s fairly obvious in log files. However, there is support for LibWhisker’s anti-IDS methods in case you want to give it a try (or test your IDS system).

Changes

This version has gone through significant rewrites under the hood to how Nikto works, to make it more expandable and usable.

  • Rewrite to the plugin engine allowing more control of the plugin structure and making it easier to add plugins
  • Rewrite to the reporting engine allowing reporting plugins to cover more and also ensuring that output is written if Nikto is quit before finishing
  • Large overhaul of documentation to document built-in methods and variables
  • Addition of caching to reduce amount of calls made to the web servers, as well as a facility to disable smart 404 guessing.
  • Addition of simple guessing for whether a system is an embedded device and to report what it is
  • Plugin to use OWASPs dictionary lists to attempt to brute force directories on the remote web server (as mutate 6)
  • Plugin to attempt to brute force domains (as mutate 5)
  • Allow username guessing (mutate 3 and 4) to use a dictionary file as well as brute forcing
  • Support for NTLM authentication
  • Lots of bug fixes and new security checks
