Trust is *not* security

February 12, 2007 (Computerworld) -- In Lancaster, Pa., last week, the county coroner was brought to court in handcuffs. A grand jury indicted Dr. Gary Kirchner, charging him with giving out his account name and password for a county Web site that contained confidential police 911 information. What kind of information? Names of accident victims and police informants, medical conditions, witness accounts, autopsy reports and not-yet-substantiated accusations. The site was the access point for real-time data generated and used by firefighters, ambulance crews and other emergency responders.

And who did the coroner allegedly give his password to? Newspaper reporters. Now there’s a trusting user.”The entire article can be found here: http://www.computerworld.com/action/article.do?command=viewArticleBasic&articleId=282376&source=NLT_SEC&nlid=38

- Clearly this guy should not have been giving out his login credentials to anyone (much less a member of the media, jeez).

- Where were the auditing procedures and detection? "...an IT staffer checked Web site logs and discovered that the site was accessed more than 50 times in two weeks from computers at a newspaper office". OK, logging was working, but if no one reviews the logs regularly, or notifications are not sent out for suspicious activity, the logs provide less value (they provided good forensic value once people realized there was a problem though).

- Thankfully "a reporter from a competing newspaper called the county to find out why he didn’t have access". Just think if this reporter didn't call; the security breach would still be going on....

This article again proves that the human element is typically the weakest when it comes to computer security. I’m betting they are going to make an example of this guy…

Stock touting and a cute little HTML trick

Stock Touting

While reading an artcile about how stock-spammers make money (you know, the emails saying a particular stock is going to be hot), I followed the research link to a Harvard web page titled Spam Works: Evidence from Stock Touts and Corresponding Market Activity. I enjoyed playing with the stock simulator at the harvard site also which simulates the scenario from both spammer and spam recipient point-of-view. It is hard to believe that this kind of social engineering works, but the facts don't lie. :) The only thing I could even *remotely* consider doing on these would be to buy short!!!!!!

A cute little HTML trick

While reading the Harvard page, I noticed this text: "If the email addresses are unreadable, click here. They cannot be copied/pasted directly from this page." which naturally made me try to highlight the authors' email address and copy them. As advertised, it appeared to mangle the email address. After looking into it a bit more, I figured out the little trick: the web page author used a combination of the PRE tag along with a STYLE attribute. I'll show this below: first with no 'style' attribute so you can see the 'real' text and then with the style attribute of "line-height: 0px" to see the obfuscated text. (I will change the email addresses of the real authors to protect their addresses...). They used the 2 line technique, multiple lines also works (as shown below).

Un-Obfuscated

r b t p o m i . o 
 o o @ o k a l c m

Obfuscated (2 lines)

r b t p o m i . o 
 o o @ o k a l c m

Obfuscated (3 lines)

r  o  p  k  i  c 
 o  t  o  m  l  o 
  b  @  o  a  .  m

Wrapup

1. If spammers can't make money (by stock touting and every other nefarious ploy, they'll stop spamming.
2. Try out this fun little HTML trick! It should help slow down unsophisticated email collectors, and if nothing else, it is like a little parlour trick to impress your geeky friends :)
