How To: Exploit DDE in Microsoft Office & Defend Against DDE-Based Attacks

In our previous article, we learned how to take advantage of a feature, Dynamic Data Exchange (DDE), to run malicious code when an MS Word document is opened. Because Microsoft built DDE into all of its Office products as a way to transfer data one time or continuously between applications, we can do the same thing in Excel to create a spreadsheet that runs malicious code when opened. The best part is, it will do so without requiring macros to be enabled.

How To: Protect Yourself from the KRACK Attacks WPA2 Wi-Fi Vulnerability

In October of 2017, Mathy Vanhoef released "Key Reinstallation Attacks: Forcing Nonce Reuse in WPA2." This paper demonstrates a way to decrypt traffic on practically any WPA2 network, the most commonly used form of wireless security (seeing as all other forms of Wi-Fi encryption have already been broken). Practically all of the network-connected devices we use will need to be updated in some way in order to protect against this vulnerability, each of them in a different way.

How To: Attack on Stack [Part 4]; Smash the Stack Visualization: Prologue to Exploitation Chronicles, GDB on the Battlefield.

Hi everyone! Last time we finished analyzing the assembly representation of our vulnerable piece of code (have I ever told you it is vulnerable?). This time we are going to introduce some fundaments about exploitation by demonstrating how to crash a program's execution. If that sounds lame, next time we will see how this crash can in fact be useful to control the program's execution, achieving remote code execution!

How To: Attack on Stack [Part 2]; Smash the Stack Visualization: Ebp, Esp, RET and Stack Frames.

Hi everyone! After messing around a little bit with IDA and Hopper disassemblers and briefly introducing you to memory, registers and Assembly, we are going to understand what happens when a process is running, which variables join the play and especially what happens when a function is called and why is this procedure-logic so interesting and useful along with the concept of stack.

How To: Use Traffic Analysis to Defeat TOR

As was mentioned by the great OTW last week, TOR, aka The Onion Router, has had its integrity attacked by the NSA. In an attempt to reduce the anonymity granted by the service, the NSA has opened a great many nodes of their own. The purpose is presumably to trace the origin of a communication by compromising some entrance and exit nodes. Once both are compromised, it is much easier to correlate traffic with a particular individual.

How To: Expand Your Analytical & Payload-Building Skill Set with This In-Depth Excel Training

It's nearly impossible not to be at least somewhat familiar with Microsoft Excel. While it's needed for many office jobs and data analysis fields, hackers could also benefit from improving their spreadsheet skills. Many white hats already know some of the essential Excel hacks, such as cracking password-protected spreadsheets, but there's so much more to know from an attack standpoint.

Hack Like a Pro: How to Hack Web Apps, Part 6 (Using OWASP ZAP to Find Vulnerabilities)

Welcome back, my tenderfoot hackers! Web apps are often the best vector to an organization's server/database, an entry point to their entire internal network. By definition, the web app is designed to take an input from the user and send that input back to the server or database. In this way, the attacker can send their malicious input back to the servers and network if the web app is not properly secured.

News: Predictions for the New Year

infosecinstitute posted a handy article about what to expect in the new year for cyber security, along with highlighting major game changers from 2015; 2016 Cyber Security Predictions: From Extortion to Nation-state Attacks - InfoSec Resources.

News: Chinese Hack of U.S. Employment Records Reveals the Weakness of Signature-Based Defense Systems

With each day that dawns, there is a new, major hack that makes the news headlines. If you are paying attention, there are usually numerous hacks each day and far more that never make the news or are kept private by the victims. Every so often, a hack is so important that I feel compelled to comment on it here to help us learn something about the nature of hacking and IT security. This is one of those cases. Last week, the U.S. Office of Personnel Management (OPM) revealed that they had been ...

News: White House Hacked by Russian Hackers!

Yesterday, April 7th, it was revealed that the United States White House had been hacked by allegedly Russian hackers. According to reports, the Russian hackers used social engineering/phishing to get a foothold in the U.S. State Department and then pivoted from that system/network to the White House. Although the White House said no confidential information was compromised, the President's appointment calendar and other information were. Attribution or "blame" for the hack was made more diff...

News: Have an NFC-Enable Phone? This Hack Could Hijack It

Some of us use our smartphones for almost everything. Manufacturers know this, so they try to make their devices as convenient as possible to use, but sometimes that convenience comes with a cost to security. The very same technology that allows you to easily share music with friends and make purchases can also put you at risk. Photo by sam_churchill
