Heading home from the CSS Security Global Summit on Friday, I got stuck in Cincinnati’s airport. While walking through baggage claim, I saw this displayed on the arrivals board: (I didn’t have a proper camera with me so, if that’s hard to read, it’s a Symantec AntiVirus Auto-Protect notification of...

or Why I Keep Harping On Blacklisting Summary: An incident reveals attempts to get around blacklisting by manipulating behavior in ASP, illustrating the weakness of blacklist approaches. A new version of UrlScan is shipping today with a change specifically to address this. Discussion:...

Occasionally, I see a security incident where one of the things that went wrong was that all of the customer's machines have the same password for the built-in administrator's account.  Whenever this happens, I suggest the PASSGEN tool that was included with the book "Protect Your Windows Network"...

I just sent a piece of e-mail to my team about input validation and SQL injection and it occurred to me that I've been meaning to get into this here, too: If you're trying to solve a SQL injection problem, input validation is NOT the answer! There, I've said it. I keep seeing blog posts, forum posts...

I’ve had an unconfirmed report that the SQL Storm attacks are now also affecting ASP.Net pages, specifically with a  URL of http://www.chliyi.com/m.js (this appears to be offline currently but I wouldn't suggest browsing there...) being injected into those pages.  My team hasn’t...

I've been working with the SWI team to write a comprehensive overview of the SQL Storm attacks with guidance for IT administrators, developers, and end users.  That article is posted at sql-injection-attack.aspx . For developers, specifically, Bala Neerumalla has written an excellent overview of...

My colleague Greg , who has forgotten more about command line scripting than I will ever know, put together a sample on CodePlex that automates finding SQL injection attacks from the ongoing mass SQL injection attack ("SQL Storm", as I saw it dubbed today).  This is a fairly convenient...

(Part 1 is here ) Previously, I provided a simple example of using parameterized queries in classic ASP; however, that sample lacked a few things such as explicit typing for the parameters. It also created a read-only ADODB.RecordSet which, obviously, isn't one-size-fits-all. Typing In the last...

Michael Howard wrote an excellent article yesterday on how the SDL addresses SQL injection . He walks through three coding requirements/defenses: Use SQL Parameterized Queries Use Stored Procedures Use SQL Execute-only Permissions As Michael points out, only the first, parameterized queries...

Kumar comments here and I think he has some questions/concerns that are worth addressing.  I'm going to add my own comments (and, please note, the comments I make here are my own and do not necessarily reflect Microsoft's corporate opinions). ----------------------------------------------------...

It looks like another wave of the mass SQL injection I talked about last month is going on.  The inserted link is different and, in the one specific incident I've seen, the source IP address is different; however, other than that, the attack looks to be identical. 2.1K websites so far, this month...

The good news is that, whatever else might happen, these guys won't get pwned by SQL injection.   (Via GrumpySecurityGuy .)

Intro It would appear that the incident I wrote about yesterday is still ongoing. I've been using a search engine to query for the *.js file that's being injected and it looks something like this: Wednesday: 10K hits (This is Avert's number. I didn't look until Thu.) Thursday: 12.1K hits Friday: 12.9K...

A number of people are reporting that 10K+ websites have been hacked via a SQL injection attack that injected a link to a malicious .js file into text fields in their database. For example, here's Avert Labs report . The reports that I've seen talk about how the .js file tries to compromise clients that...

LogParser is one of my absolute favorite tools, particularly for doing incident response. I use it a lot to extract and order data into a timeline (hmmm...that's a good topic for a future post). When I moved to Vista, I found one annoyance, though. The log file format in Vista has changed from *.evt...

After investigating an ARP spoofing incident recently, I started thinking of how we could easily ferret out this sort of information when responding to a potential incident. In this particular case, there were two important parts of the attack: ARP spoofing forced all traffic bound for the default gateway...

I recently worked on an interesting incident response with several of my colleagues. The problem, as defined by the customer, is that the following code is being injected into some websites (both external and internal to his environment) that his users are surfing: <iframe src=http://<redacted>...
