The Infosec London Conference is coming up this week, running April 23-25 at the Earl’s Court Exhibition Center. Cisco will be there of course, in a booth showing the latest Cisco security innovations and presenting four papers on:
• “Securely Accelerate Access to Data Center Applications” (Tuesday, April 23, 10:30)
• “The Changing Landscape of Identity: Is 802.1X Enough?” (Tuesday, April 23, 16:00)
• “Outbound Content Security” (Wednesday, April 24, 10:30)
• “BYOD Demo—Onboarding the iPad With Cisco Identity Services Engine” (Thursday, April 25, 10:30)
While taking in Cisco content at the show is definitely a must do item, I have a little insider travel tip to impart. Show goers should also check out the small and emerging companies usually found next to the walls in the convention hall. Read More »

In recent weeks, the occurrence of brute force login attempts targeting WordPress and Joomla installations have significantly increased in volume, with some entities reporting triple the attempts seen in the past. The attack volume has been so severe that it has led some hosting providers to block all attempts to access wp-login.php, even for site owners or administrators. While blocking all access outright might seem a bit draconian, about 25% of websites globally include WordPress installations – a tremendous attack surface if left undefended.
During the course of its investigation, Cisco TRAC discovered a repository of data believed to potentially be feeding the brute force login attempts. The trove included user lists, site lists, and password lists. Additionally, there is a list that appears to be a compilation of usernames and passwords used in previous brute force login attempts, scrapings from phishing and cracking forums, as well as the Nmap password list of common passwords. The compiled list has over 25,000 entries, half of which were duplicates. After cleaning up the duplicates, we were left with 783 unique usernames and 11,001 unique passwords – resulting in over 8.6 million possible combinations. However, it doesn’t appear the attackers are going to that extent; the total list of username/password pairs (with dupes removed) contained just over 13,000 combinations.
Examples of some of the more complex passwords discovered include:

The Common Vulnerability Reporting Framework (CVRF) is a security automation standard intended to make your life easier by offering a common language to exchange traditional security and vulnerability bulletins, reports, and advisories. You can read more about it on the official ICASI CVRF 1.1 page, in my CVRF 1.1 Missing Manual blog series, or in the cvrfparse instructional blog. CVRF 1.1 has been available to the public for almost a year and we would like to know how its helped and how we can improve it. Please take a moment to take the poll and please feel free to share it with any interested parties. Comments are encouraged and welcomed. The more feedback we get, the more we can improve CVRF.

UPDATE: Webcast information is also now available at the Cisco Live 365 site
Many network security administrators are struggling to keep their network “up-to-date” with the constant release of new vulnerabilities and software fixes. At the same time, they’re under pressure to provide near 100% availability of key business services and systems. Every time a vendor discloses a security vulnerability, network security administrators must identify affected devices and (in numerous cases) upgrade such devices. These activities can take hours, days, or even weeks depending on the size of the organization. For instance large enterprises and organizations may have thousands of routers and switches that need to be assessed for the impact of any given vulnerability. Cisco is helping customers by adopting cutting-edge security automation standards such as the Open Vulnerability and Assessment Language (OVAL) and the Common Vulnerability Reporting Framework (CVRF).
In the following blog posts, I’ve provided details about how security automation is helping customers:
Additionally, my colleague Mike Schiffman has posted several posts explaining CVRF.
Webcast took place on Tuesday, April 23rd at 10:00 a.m. EST (14:00 GMT). Over 150 customers from 29 countries learned about security automation; Cisco’s machine readable content strategy; and vulnerability assessment using OVAL. We discussed how customers can use OVAL to quickly assess the effects of security vulnerabilities in Cisco IOS Software devices. The recording is now available:

At 10:30 UTC one of the botnet spam campaigns we discussed yesterday took a shift to focus on the recent explosion in Texas. The miscreants responded to the tragic events in Texas almost immediately. The volume of the attack is similar to what we witnessed yesterday with the maximum volume peaking above 50% of all spam sent. We’ve seen 23 unique sites hosting the malware. This is an attempt to grow the botnet.
