Introduction Attacks against DNS, and particularly the concept of DNS cache poisoning has been known for over a decade (e.g. [2] section 5.3 was published in 1989 and [3] was published in 1993). A concise threat analysis for the existing DNS infrastructure can be found in [4]. The focus of this paper is on DNS cache poisoning attack. Typically, a DNS query is sent over the connectionless UDP protocol. The UDP response is associated with the request via the source and destination host and port (UDP properties), and via the 16 bit transaction ID value (the response’s transaction ID should be identical to the request’s transaction ID). Assuming that an attacker knows that a DNS query …

The reasons to fight spam on Yahoo! Messenger

I came across a disturbing story on Yahoo! News last week called “Confessions of a former spammer”. It detailed the practices of a former email spammer named “Ed” who earned a as much as $15,000 per week sending emails that promoted pills, porn and casinos. Like any good opportunist, Ed has written a book about his exploits. But just a read of the news story will give you a feel for what it’s like to work in this seedy sector of the internet. Read the full story Once my nausea subsided, reading the article got me to thinking about our own spam challenges. While we have powerful anti-spam protections in place on the Yahoo! network and in Messenger specifically, the ultimate spam protection comes from our millions of users who take the time to report unwanted messages.

Quick Fixes for Nasty Vista Problems

Can’t Read Reader You can’t consider a Windows operating system installation complete until you’ve got Adobe Reader on your system. So many assets on the Web come in Acrobat form, and unless you have the full program on your software shelf you need Reader to check them out.If you’re the kind of power-user who turns off User Account Control, or if you log on right into the default administrator account, you might notice that Adobe Reader 8 won’t install after download—or after you discover it on some other media that included it.

How to handle suspicious e-mail

1. If you think you’ve received a phishing e-mail message, do not respond to it. 2. Report suspicious e-mail. Report the e-mail to the faked or “spoofed” organization. Contact the organization directly—not through the e-mail you received—and ask for confirmation. Or call the organization’s toll-free number and speak to a customer service representative. Report the e-mail to the proper authorities, including the FBI, the Federal Trade Commission (FTC), and the Anti-Phishing Working Group. For more information on how to report phishing scams, read What to do if you’ve responded to a phishing scam. 3. Don’t click links in e-mail messages.

How to safely remove software and files from your PC

Like many mothers, Andrea Grace will sit down at her PC to check e-mail, only to find that her kids, Jason, 8, and Rachel, 10, have installed some new programs. “Between those CD-ROM games found in cereal boxes and downloaded Neopets, there are now icons all over the place,” says Grace. “And of course they don’t play half the games. If I ran out of space I wouldn’t know how to delete them,” she admits. Grace isn’t alone—it’s not uncommon to fill space on a hard drive with games, productivity programs, or files, such as music, digital photos, and video clips. Some technology analysts believe that we use less than 10 percent of the programs installed on our computer.
