Metagoofil makes metadata extraction easy

| 0 comments

Metagoofil is an information gathering tool designed for extracting metadata of public documents (pdf, doc, xls, ppt, docx, pptx, xlsx) belonging to a given target or victim website. The tool will perform a search in Google to identify and download the documents to local disk and then will extract the metadata with different libraries like Hachoir, PdfMiner and others. With the results it will generate a report with usernames, software versions and servers or machine names that will help Penetration testers in the information-gathering phase. Metadata serves five purposes: resource description; information retrieval; management of information; rights management, ownership and …

Homebrew and not the beer kind

| 0 comments

Recently I had a need to install wget and Python on OS X Mavericks and anyone running a Mac can understand the pain point with installers outside of the Apple App Store. Before anyone starts asking the question why not use curl? That is like asking why not use Microsoft Windows? Now I am not bashing Windows because I use this  operating system depending upon my needs and task at hand. As a side note, it is possible to use Xcode and curl to compile and install wget, but why work harder rather than smarter? If you wish to take …

Email and file security using GPGTools

| 0 comments

Here we are talking about encryption again. Those men in black seem to be everywhere these days and I am not sure about you, but trust seems to be more and more difficult to come by these days. Before I get started about the use of GPGTools, I want to step up to the soapbox and talk a little bit about email phishing since this post is addressing email security. Phishing is a type of fraud that seeks to acquire a user’s credentials by deception. It includes theft of passwords, credit card numbers, bank account details or any other types …

TrueCrypt goes dark

| 0 comments

Today was an interesting day in term of security within the encryption community. The developers of TrueCrypt have made the following statement: “WARNING: Using TrueCrypt is not secure as it may contain unfixed security issues.” It is not clear exactly what is driving this decision and one can only guess at this point unless the development team comes out an conclusively comments on what the driving factor was. What makes this even more interesting, at least from my perspective, is the fact a security audit was just completed in April 2014. At that time, the phase 1 audit did not …

Doomed software developers that do not understand security

| 0 comments

Say for a moment you have a software development task to notify end users of a specific event and this notification is critical for a number of reasons. Would the average development team understand the best architectural design? What if I told you that you development team goes off and creates the software and it is a success, but in no time the network becomes unstable and eventually crashes. Sound impossible? Not if the software essentially performed a denial-of-service (DoS) attack. In a DoS attack, an attacker attempts to prevent legitimate users from accessing information or services. By targeting your …

DNS rebinding and IDS signatures

| 0 comments

DNS rebinding attacks have been around for a number of years and still present challenges today. This type of attack can propagate via malware and individuals who do not act appropriately to protect themselves often will become unknowing and unwilling victims. Often this risk is in play because of popular technologies such as Flash and the lack of common standards across vendors. DNS Rebinding Analysis I found the concept of DNS rebinding to extremely complicated. Upon investigation, I found that web browsers handle DNS queries differently during the Time to Life (TTL), for example, Internet Explorer uses what is called …
