Thousands Hooked by Malware from Big Sites


If I recall this is not the first time this has happened, delivering viral payloads via banner ads and flaws in scripting.

It seems that malware peddlers are getting more aggressive though, it obviously shows there is actual monetary value in infecting people and stealing their data.

A subtle form of social engineering too, by leveraging on the trust a user gives to a big name site, they also pass that trust on to the banner ads displayed on that site.

Thousands of PC users have been duped into surrendering sensitive information and installing malicious software after falling victim to a complex scam that continues to plague well-known websites, a researcher warns.

The scam is the latest to piggyback on banner ads that are fed to high-traffic destinations. Malicious code hardwired into the ads prompts a pop-up that warns of a bogus security threat on the visitor’s machine. It offers to fix the problem in exchange for a fee and for credit card information. The ad then attempts to install a back door on the victim’s machine.

There are thousands of sites with these malware infested banner ads running, so be careful. It seem you’re no longer safe even if you stay away from the seedier parts of the web.

I’d guess though the vast majority of readers here wouldn’t be stupid enough to download a prompted ‘security’ fix which randomly appeared.

Jackson estimates the rogue ads have appeared on anywhere from “several hundred to 1,000” sites, which tend to be related to television and entertainment. Based on unique signatures of the javascript used in the attack, which researchers have seen passing over the net, he estimates thousands of people have fallen for the ruse.

Jackson has managed to shut down at least two servers serving the bad ads, but warns at least two more are still operational. He declined to identify the servers or the websites by name.

I hope they manage to shut down the rest and save all the witless morons surfing the web from more infestations and information leakage.

WSBang – Python Based SOAP Services Testing Tool


WSBang is designed to be a lightweight, open source fuzzer for web services. It takes as input the URL or file system location of a WSDL for the web service to be tested. Upon completion, a simple HTML view of the test results will be displayed.

Method parameters are fuzzed based on their type as specified by the WSDL. The data used for each type can be specified in the “DataDef.xml” file supplied. In addition, default arguments for parameters can be specified in the same file in the Argument definitions.

  • Takes URL of WSDL as input
  • Fuzzes all methods and parameters in the service
  • Identifies all methods and parameters, including complex parameters
  • Fuzzes parameters based on type specified in WSDL
  • Reports SOAP responses and faults

Prerequisites:
SOAPpy version 0.11.6.

Use:
WSBang.py [URL of WSDL]

Files included:
WSBang.py – The main execution code for WSBang.
Fuzzer.py – Classes that support WS analysis and the fuzz engine.
DataProvider.py – Classes that provide fuzz data and default arguments.

You can download WSBang here:

MPAA Hacker Robert Anderson Revealed


This story reads like something from one of those glamourised Hollywood ‘hacker’ movies like Swordfish or Antitrust.

The legendary MPAA hacker has been revealed, and it looks like he himself got social engineered and dumped…he should have realised when you are playing with unscrupulous people you are setting yourself up to get screwed.

Promises of Hollywood fame and fortune persuaded a young hacker to betray former associates in the BitTorrent scene to Tinseltown’s anti-piracy lobby, according to the hacker.

In an exclusive interview with Wired News, gun-for-hire hacker Robert Anderson tells for the first time how the Motion Picture Association of America promised him money and power if he provided confidential information on TorrentSpy, a popular BitTorrent search site.

According to Anderson, the MPAA told him: “We would need somebody like you. We would give you a nice paying job, a house, a car, anything you needed…. if you save Hollywood for us you can become rich and powerful.”

Promised him everything he’d dreamed of eh? Then in the end…fascinating read anyway.

But once Anderson turned over the data and cashed the MPAA’s check, he quickly realized that Garfield had no further use for him. “He lost interest in me,” he says. Anderson felt abandoned: During negotiations with Garfield, the hacker had become convinced he was starting a long-term, lucrative relationship with the motion picture industry. “He was stringing me along personally.”

Hollywood’s cold shoulder put Anderson’s allegiance back up for grabs, and about a year later he came clean with TorrentSpy’s Bunnell in an online chat. “‘I sold you out to the MPAA,'” Anderson says he told Bunnell. “I felt guilty (for) what happened and I kinda also thought at that point the MPAA wasn’t going to do anything.”

Some pretty tricky business..so if you are a hacker for hire, you’d better be careful who you are dealing with.

Pass-The-Hash Toolkit v1.1 Available for Download


The concept of passing the hash on Windows came about a while ago, now there’s a tool for it in it’s second revision (which fixed some problems with foreign language Windows versions and Windows 2003).

The Pass-The-Hash Toolkit contains utilities to manipulate the Windows Logon Sessions mantained by the LSA (Local Security Authority) component. These tools allow you to list the current logon sessions with its corresponding NTLM credentials (e.g.: users remotely logged in thru Remote Desktop/Terminal Services), and also change in runtime the current username, domain name, and NTLM hashes (YES, PASS-THE-HASH on Windows!).

Utilities in the toolkit:

IAM.EXE: Pass-The-Hash for Windows. This tool allows you to change your current NTLM credentials withouth having the cleartext password but the hashes of the password. The program receives a username, domain name and the LM and NT hashes of the password; using this it will change in memory the NTLM credentials associated with the current windows logon session.

WHOSTHERE.EXE: This tool will list logon sessions with NTLM credentials (username,domain name, LM and NT hashes). Logon sessions are created by windows services that log in using specific users, remote desktop connections, etc.

GENHASH.EXE: This is a small utility that generates LM and NT hashes using some ‘undocumented’ functions of the Windows API. This is a small tool to aid testing of IAM.EXE.

You can download Pass-The-Hash Toolkit v1.1 here:

pshtoolkit_src_v1.1.tgz

Tutorial for Fuzzled – Writing a Fuzzer with the Fuzzled Framework


If you remember we mentioned Fuzzled a little while back, the PERL fuzzing framework. Apparently Fuzzled 1.1 should be coming out soon.

Fuzzled is a powerful fuzzing framework. Fuzzled includes helper functions, namespaces, factories which allow a wide variety of fuzzing tools to be developed. Fuzzled comes with several example protocols and drivers for them.

Someone was kind enough to write a short paper on how to use fuzzled to write a simple fuzzer. The paper includes some techniques used to dismantle protocols including documentation, observation and static analysis.

To quote the author:

The paper includes some of the techniques I use to dismantle protocols including documentation, observation and static analysis. It then moves on to the fundamentals of implementing a protocol using the framework. I talk about base requests, namespaces and tieing them together with factories with reference to Fuzzled::Protocol::HTTP, an example included in the framework. The paper also highlights a few tricks to the framework, including developing multi-threaded fuzzers, identifying offsets and parsing packets. It ends with my techniques to identify vulnerabilities highlighted by fuzzers.
