Much ado about Conficker

Posted by Jaime Raphael Licauco, CISSP, GSEC on March 31, 2009

There’s been much hullabaloo about the Conficker worm lately, especially since it’s supposed to phone home to around 500 servers (from a possible 50,000) this coming April 1st. So much so that even the New York Institute of Photography has sent an e-mail warning and telling photographers to back up their files just in case. Microsoft started a group called Conficker Cabal around mid last month that has unfortunately only had partial success, since on March 5th, around a fifth of infected machines updated themselves from variant B to variant C.

I doubt that typical users will get affected by it that much… BUT if you’re an Admin that wasn’t able to patch soon, then you may be in for a long day.

Researchers from the Honeynet Project have released a proof of concept (PoC) to detect the worm by using network scanners. The PoC code can be found at the Computer Science site of the University of Bonn.

Nmap has released 4.85 Beta 5 which contains the Conficker detection logic, and so have Qualys and nCircle.

You can also check out Dan Kaminsky’s personal blog for more info. By the way, his blog has a cool little tool that may detect if your DNS is vulnerable to what he discovered last year (check out this illustrated guide to the vulnerability).

Seminars and Conventions
ISACA Manila will be holding their annual conference with the theme, “IT Governance: Solving the Puzzle” this coming April 14 and 15 at the Renaissance Hotel, Makati City. The conference will have a plenary session on IT Governance topics such as IT Management, IT Security, IT Auditing and IT Risk Management.

One of the reasons why I started this site is because there seems to be a paucity of Information Security News about the Philippines. Sometimes its even hard to find out about Conferences and Seminars in Metro Manila. Its refreshing to be able to find the following:

(YouTube, from GMANews.TV) IMBESTIGADOR – Friendster Hacker (Identity Theft, Cybercrime)
(GMANews.TV, Old News) Woman who hacked Friendster account faces estafa raps

Just in case you need help in figuring out HijackThis, there’s this useful tutorial on PCHell.com. If you already use HijackThis and don’t understand parts of the log file, the tutorial points you to the HijackThis Logfile Analysis site.


The recent Twitter hack shows that some Admin level personnel should follow Admin Password Best Practices. Apparently the Admin’s password was, ‘happiness’, as is discussed in this Wired blog.

Secure Coding and Application Dev
What is probably the most significant security news item of the past week is the release of SANS and Mitre of their Top 25 errors and how to fix them. It’s been said that around 85% of criminal activities on the net stem from the current crop of Top 25 flaws. The Top 25 list is divided into three broad categories namely: Insecure Interaction Between Components, Risky Resource Management, and Porous Defenses.

The PDF version of the Top 25 is available here.

The Software Assurance Forum for Excellence in Code (SAFECode) has made two publications available to help eliminate the Top 25 errors, its Guide to the Most Effective Secure Dev Practices in Use Today, and Software Assurance: An Overview of Current Industry Best Practices.


Social Engineering
A rehash of old tactics can be seen in an E-mail purportedly from Northwest Airlines (but actually carries a zipped trojan file), and malware spreading websites that claim US President elect Obama won’t be taking the oath of office on the 20th. This just strengthens the argument that your personnel and their security awareness training are now your first line of defense, and not your perimeter firewall.

This is related to the fake Christmas and holiday greetings that been sent every year for the past few years, which was seen again this past Christmas.


Malware
The Downadup (also known as Conficker) Worm versions A, B and C that exploits what Microsoft released an out of band patch for in late October ’08, and weak Admin passwords, is said to have infected an “amazing” 9 million PC’s according to F-Secure researchers. If you’re wondering how they got to this astonishing figure, check out F-Secure’s Blog.

Secure deletion, reuse or disposal
According to new research led by Craig Wright, it just takes one re-write to securely wipe the data from a hard drive. This talks about a complete sector by sector overwrite of a hard drive.

Articles on this can be found on Heise Security and SecurityFocus. The paper was presented at the Fourth International Conference on Information Systems Security (ICISS) in Hyderabad, India and can be purchased here.


Encryption
Heise Security has published an in depth article on how modern cryptological attacks are done in their article, “Cheap Cracks“.


Patches and Change Management
Oracle released fixes for 41 different flaws this month and Microsoft released a single patch that closed three flaws.

(Heise Security) Numerous security updates from Oracle
(Heise Security) Microsoft closes three holes in Windows
Microsoft issues patches for ‘nasty’ Windows bugs

A vulnerability in SAP GUI has also been found and a patch has been released and is available to registered SAP users.

The Windows Security Blog has announced a new Beta called Sundance that could help secure Windows and Office 2007 installations.

In relation to what I wrote about around a month ago regarding wireless networks, the crack in the WPA protocol only affects the TKIP version and not AES, so the solution is to simply switch from TKIP to AES as is detailed in this article from Search Security.com, “Cracks in WPA? How to continue protecting Wi-Fi networks“.

A rootkit was found in an Enterprise Information Security software, reports Heise Security and The Register.

Another vulnerability was found in the popular VLC media player. So if you can, update.

The Chicago Tribune reports that a new round of cyber attacks has the Pentagon worried. They normally get a whole number of attacks per day, however, the magnitude and way the new attacks are being done are apparently designed to specifically attack military networks. Heise also covers the same topic here and here.

The Linux on iPhone project has released the first results of its project.

Anti-virus seems to be ineffective versus new malware that makes zombies out of PCs. Stuart Staniford talks about it in his blog.

WordPress update fixes XSS vulnerability.

Google denies security hole in GMail.

Microsoft adds malware detection to its Webmaster tools. Speaking of Microsoft, a new windows worm builds a massive botnet worth around half a million computers and growing.

For the first time, Apple quietly recommended Anti Virus software in a technote. About.com has Mac Anti-Virus recommendations. iAntivirus and ClamXav are free.
