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.

How To: Hack Forum Accounts with Password-Stealing Pictures

The pictures we upload online are something we tend to think of as self-expression, but these very images can carry code to steal our passwords and data.
