Equifax Data Breach – Hack Due To Missed Apache Patch


The Equifax data breach is pretty huge with 143 million records leaked from the hack in the US alone with unknown more in Canada and the UK.

Equifax Data Breach - Hack Due To Missed Apache Patch

The original statement about the breach is as follows for those that weren’t up to date with it, which came out Sept 7th (4 months AFTER the breach happened).

Equifax Inc. (NYSE: EFX) today announced a cybersecurity incident potentially impacting approximately 143 million U.S. consumers. Criminals exploited a U.S. website application vulnerability to gain access to certain files. Based on the company’s investigation, the unauthorized access occurred from mid-May through July 2017. The company has found no evidence of unauthorized activity on Equifax’s core consumer or commercial credit reporting databases.

The information accessed primarily includes names, Social Security numbers, birth dates, addresses and, in some instances, driver’s license numbers. In addition, credit card numbers for approximately 209,000 U.S. consumers, and certain dispute documents with personal identifying information for approximately 182,000 U.S. consumers, were accessed.


So pretty serious stuff with a kit ripe for social engineering and some pretty heavy weight identity theft.

Some good info in this video, skip to 3:02 for the Equifax story coverage:

Just today the entry point has been published, which is pretty unusual in these type of cases to get ANY info other than the fact it happened. It’s linked to a flaw in Apache Struts that was public in March 2017.

Equifax has been intensely investigating the scope of the intrusion with the assistance of a leading, independent cybersecurity firm to determine what information was accessed and who has been impacted. We know that criminals exploited a U.S. website application vulnerability. The vulnerability was Apache Struts CVE-2017-5638. We continue to work with law enforcement as part of our criminal investigation, and have shared indicators of compromise with law enforcement.

As the Apache Foundation pointed out earlier this week, it reported CVE-2017-5638 in March 2017. Doubt us? Here’s the NIST notification that mentions it as being notified on March 10th.

It’s a pretty nasty situation especially if you watched the video above and you realise that Equifax is also managing to monetize their screw up.

At least a good amount of information is coming out around this case so we can keep an eye on it and see what else turns up.

Seth – RDP Man In The Middle Attack Tool


Seth is an RDP Man In The Middle attack tool written in Python to MiTM RDP connections by attempting to downgrade the connection in order to extract clear text credentials.

Seth - RDP Man In The Middle Attack Tool


It was developed to raise awareness and educate about the importance of properly configured RDP connections in the context of pentests, workshops or talks.

Usage of Seth RDP Man In The Middle Attack Tool

Run it like this:

Unless the RDP host is on the same subnet as the victim machine, the last IP address must be that of the gateway.

The script performs ARP spoofing to gain a Man-in-the-Middle position and redirects the traffic such that it runs through an RDP proxy. The proxy can be called separately:


Requirements for Seth RDP MiTM Attack Tool

  • python3
  • tcpdump
  • arpspoof (arpspoof is part of dsniff)
  • openssl < 1.1.0f

OpenSSL should not be too recent, as it does not support older versions of the SSL protocol and thus may be incompatible with older version of the Windows RDP client.

dcrawl – Web Crawler For Unique Domains


dcrawl is a simple, but smart, multithreaded web crawler for randomly gathering huge lists of unique domain names.

dcrawl - Web Crawler For Unique Domains


How does dcrawl work?

dcrawl takes one site URL as input and detects all a href= links in the site’s body. Each found link is put into the queue. Successively, each queued link is crawled in the same way, branching out to more URLs found in links on each site’s body.

dcrawl Web Crawler Features

  • Branching out only to predefined number of links found per one hostname.
  • Maximum number of allowed different hostnames per one domain (avoids subdomain crawling hell e.g. blogspot.com).
  • Can be restarted with same list of domains – last saved domains are added to the URL queue.
  • Crawls only sites that return text/html Content-Type in HEAD response.
  • Retrieves site body of maximum 1MB size.
  • Does not save inaccessible domains.

dcrawl Usage


Example:

There are other tools which do similar things, or could be scripted together recursively to perform a similar kind of task – but nothing this focused. Examples would be:

Host-Extract – Enumerate All IP/Host Patterns In A Web Page
Recon-ng – Web Reconnaissance Framework

Time Warner Hacked – AWS Config Exposes 4M Subscribers


What’s the latest on the web, Time Warner Hacked is what it’s about now as a bad AWS S3 config (once again) exposes the details of approximately 4 Million subscribers.

Time Warner Hacked - AWS Config Exposes 4M Subscribers


This follows not long after the Instagram API leaking user contact information and a few other recent leaks involving poorly secured Amazon AWS S3 buckets and I’d hazard a guess that it won’t be the last.

Records of roughly four million Time Warner Cable customers in the US were exposed to the public internet after a contractor failed to properly secure an Amazon cloud database.

Researchers with security company Kromtech said freelancers who handled web applications for TWC and other companies had left one of its AWS S3 storage bins containing seven years’ worth of subscriber data wide open on the ‘net. That data included addresses and contact numbers, information about their home gateways, and account settings.

Just before the weekend, Kromtech said the vulnerable AWS instance was operated by BroadSoft, a cloud service provider that had been using the S3 silos to hold the SQL database information that included customer records.

When Kromtech spotted the repository in late August, it realized that databases had been set to allow public access, rather than limit access to administrators or authorized users.

“It is most likely that they were forgotten by engineers and never closed the public configuration. This would allow anyone with an internet connection to access extremely sensitive documents,” Kromtech’s Bob Diachenko said.


This is also not the first Data Leak to involve a poorly secured Amazon S3 bucket (to be fair, AWS IAM is pretty complex).

Still, that’s no excuse if your people can’t understand it – hire someone who can secure your buckets properly (per app, separate users for each). Too many dev teams just use the root account credentials for accessing everything which is the worse possible way to use S3.

“Not only could they access the documents, but any ‘authenticated users’ could have downloaded the data from the URL or using other applications. With no security in place, just a simple anonymous login would work.”

The researchers found that the database included information on four million TWC customers collected between November 26, 2010 and July 7, 2017. The exposed data included customer billing addresses, phone numbers, usernames, MAC addresses, modem hardware serial numbers, account numbers, and details about the service settings and options for the accounts.

A spokesperson for TWC parent company Charter said the telly giant was aware of the cockup and is notifying the customers who were exposed.

“Upon discovery, the information was removed immediately by the vendor, and we are currently investigating this incident with them,” Charter said. “There is no indication that any Charter systems were impacted. As a general security measure, we encourage customers who used the MyTWC app to change their user names and passwords.”

This Time Warner hack has exposed some pretty juicy information, thankfully no credit card details appear to have been leaked but everything else you need to social engineer an account is there, or even in a worse case scenario to hijack someone’s identity.

It’s also not really surprising to me that it’s been that way for some time (possibly even 7 years?) as by default S3 is publically accessible and if you don’t change it nothing will break so it’s very easily forgotten.

Wikto Scanner Download – Web Server Security Tool


Wikto 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.

Wikto Scanner Download - Web Server Security Tool


It’s Nikto for Windows basically with some extra features written in C# and requires the .NET framework.

What is Wikto

Wikto is not a web application scanner. It is totally unaware of the application (if any) that’s running on the web site. So – it will not look for SQL injection problems, authorization problems etc. on a web site. It is also not a network level scanner – so it won’t try to find open ports or see if the web site is properly firewalled. Wikto rather operates between these two levels – it tries to, for instance, find interesting directories and files on the web site, it looks for sample scripts that can be abused or finds known vulnerabilities in the web server implementation itself.

How does Wikto work?

To understand the Wikto component of the application you need to understand what Nikto is. Nikto is a text based web server vulnerability scanner written in PERL by the good guys at CIRT. Nikto scans for over 3000 potential problems on a web server. It is beyond the scope of the document to explain what types of checks it performs – you can read all about on the Nikto post.

Like the BackEnd miner, the scanner has the ability to perform fuzzy logic on the responses thereby greatly reducing the occurrence of false positives. It also has the ability to import directories from both the BackEnd miner and the Googler.

Wikto vs Nikto


Wikto is not just Nikto for Windows. The Nikto scan is only of its many functions (and it does the Nikto scans totally different than Nikto does).

It also has additional functionality including Fuzzy logic error code checking, a back-end miner, Google assisted directory mining and real time HTTP request/response monitoring.

Wikto Web Security Scanner Requirements

To get the most out of the app you also need to install the following:

  1. WinHTTrack – A web mirroring tool (you can use the default install)
  2. HTTprint – A web server fingerprinting tool (by default, Wikto looks for this in the c:\Tools directory, but you can configure it)

You can download Wikto here:

Reaver Download – Hack WPS Pin WiFi Networks


Reaver download below, this tool has been designed to be a robust and practical tool to hack WPS Pin WiFi Networks using WiFi Protected Setup (WPS) registrar PINs in order to recover WPA/WPA2 passphrases.

Reaver Download - Hack WPS Pin WiFi Networks


It has been tested against a wide variety of access points and WPS implementations.

The original Reaver implements an online brute force attack against, as described in here [PDF]. reaver-wps-fork-t6x version 1.6b is a community forked version, which has included various bug fixes and additional attack method (the offline Pixie Dust attack).

How to use Reaver

Depending on the target’s Access Point (AP), to recover the plain text WPA/WPA2 passphrase the average amount of time for the transitional online brute force method is between 4-10 hours. In practice, it will generally take half this time to guess the correct WPS pin and recover the passphrase. When using the offline attack, if the AP is vulnerable, it may take only a matter of seconds to minutes.


Deprecated and temporary left behind options

This fork supports the Pixie Dust attack which will work against modern routers, you can find a list of routers and which types of attack they are vulnerable to here.

There are other tools which rely on Reaver for WiFi hacking such as:

wifite – Mass Wifi WEP / WPA Key Cracking Tool
Fern Wifi Cracker – Wireless Security Auditing Tool
