A few years ago, I published a blog entry called Signed Java Applet Security: Worse than ActiveX? In that entry, I explained the problems that arise when a vulnerability is discovered in a signed Java applet. Let's see how the Cisco AnyConnect vulnerability is affected.
Microsoft recently released a component for Office called Office File Validation that is supposed to help protect against attacks using malformed files. Because I recently performed file fuzzing tests on Microsoft Office, I decided to test the effectiveness of Office File Validation.
Recently, Dan Kaminsky published a blog entry that compared the fuzzing resiliency of Microsoft Office and Oracle OpenOffice. This blog entry contains the results from a similar test that I performed in November 2010. Also included are some other aspects of the Office suites that can affect the software's security.
Version 2.0 of the CERT Basic Fuzzing Framework (BFF) made its debut on Valentine's Day at the 2011 CERT Vendor Meeting in San Francisco. This new edition has a lot of cool features that we'll be describing in more detail in future posts, but we wanted to let you know that it's available so that you can download and try it.
The report draws on related work such as OWASP but comes from a different point of view. While OWASP is focused on developing web applications securely, this report focuses more on situations where you don't have that control, but you need to protect servers and clients from web-based threats. The report may help you answer the following questions:
What kinds of network monitoring do you need to do?
How do you identify the attacks?
How do you prevent them at the network level?
At more than 100 pages, the report is as comprehensive as we could make it and still get it out in a (relatively) timely manner.
Hi, folks. As you can see, we've changed the name of the Vulnerability Analysis Blog to the CERT/CC Blog. With this name change, we're expanding the focus of the blog to include content from other technical teams.
The current RSS and Atom feeds will continue to work, but you may want to update to the corresponding new feed location now (RSS, Atom) in order to avoid any problems in the future.
Past blog entries will continue to be available at the existing URLs.
Recently the Network Situational Awareness team at CERT has been researching the characteristics of malicious network touchpoints. The findings of this initial research are very telling as to the true state of security on the internet.
The threat of insiders causing physical harm to fellow employees or themselves at an organization is real. In 2015 and 2016 alone, there were shootings in the U.S. by current or former employees in various workplaces, including at a television...
