Spammers Using Shortened .gov URLs
hypnosec writes "Cyber-scammers have started using '1.usa.gov' links in their spam campaigns in a bid to fool gullible users into thinking that the links they see on a website or have received in their mail or newsletter are legitimate U.S. Government websites. Spammers have created these shortened URLs through a loophole in the URL shortening service provided by bit.ly. USA.gov and bit.ly have collaborated, enabling anyone to shorten a .gov or .mil URL into a 'trustworthy' 1.usa.gov URL. Further, according to an explanation provided by HowTo.gov, creating these usa.gov short URLs does not require a login." Which might not be a big deal, except that the service lets through URLs with embedded redirects, and it is to these redirected addresses that scammers are luring their victims.
...just like other .gov websites
Enjoy life! This is not a dress rehearsal.
You can always trick the user with a .gov hyperlink to some other tld off course.
Isn't the major WTF in the second stage of the "attack", a .gov site that will happy redirect to _any_ site feed to its (link) script? Obviously the .gov shortening will help in the "attack" on people that do not click everything they see.
It's obviously a Libyan plot.
...will get you real federal prison time. http://www.law.cornell.edu/uscode/text/18/912
... but a url which starts with "1.usa.gov" doesn't strike me as particularly trustworthy.
Pretty good is actually pretty bad.
Obama has been spamming for donations from @whitehouse.gov for years!
It tracks the links that a user clicks on:
When you browse any web site, one log file entry is created for every page you visit --- with the information where you came from. When you follow a link from one web site "A.gov" to another web site "B.com", then this data would be stored in the log file of "B.com" --- but not in the log files of "A.gov".
By jumping through the LinkClick.aspx script, the site "A.gov" catches this information (where do our visitors go to?) in their log files.
I've been getting spams from IRS.gov. First the content doesn't apply to me, and they are grammatically incorrect. But I can see somebody being fooled. The URL is .irs.gov/get action.aspx. Seeing IRS.gov makes it seem real. Knowing better stops me from clicking the link (but I want to, just to see what it does).
I thought it might be a SQL injection hack. Great, now there are more .gov attacks, built by the govt.
What will they think of next?
Admittedly, before go.usa.gov went live I needed to use a shortening service on occasion, but I always used tinyurl preview links when that came up. I figured that it was the least I could do to improve transparency for users.
Stop learning! Only you can prevent esoterrorism.
Everyone is responsible for knowing where they are clicking through to. Nobody bothers to check the actual target URL. A simple answer is:
1. Turn on the status bar at the bottom of the browser window.[usually View/Toolbars/Status Bar (checkbox)]
2. Each URL pointed to will show the actual target in the status bar.
3. Make sure that's really where you want to go, and DON'T click if you don't recognise the URL shown there.

Old news is old.
SecureWorks already reported on this last week:
http://www.secureworks.com/cyber-threat-intelligence/blog/spam/government-websites-abused-ongoing-spam-campaign/
Just like their AV protection, Symantec is a week late :)
They're not so much used for tracking as popping up "you are now leaving our site, we're not responsible for this content" advisories. I have yet to see a US government agency website that doesn't do this - and they're virtually the only ones who do.
Please help metamoderate.
There is no reason an e-mail needs to contain a obfuscated link. Its either a bound through some marketing tracking crap (therefore is spam) or it might be malicous. The best way to approach this is just start dropping mails that contain links with the URL of any known shorteners.
It won't take long for legitimate and semi-legitimate senders to realize they just can't use such links because it means their messages don't get past recipient spam filters. Honestly from a security standpoint I can't see why it should ever be considered okay to follow an obfuscated link in an otherwise unauthenticated and untrusted document like an E-mail. We spend years trying to teach people not to click links in mails without checking they point where the display text says they do first and stupid bit.ly came along and make that impossible for most users.
Now maybe if the message is signed and the spam gateway can verify the signature belongs to someone or some entity on the white list fine, but otherwise discard. As network and mail admins I think we owe it to our users to take hard line against this practice.
Repeal the 17th Amendment TODAY! Also Please Read http://www.gnu.org/philosophy/right-to-read.html
Government IT of any kind is mostly inept. I used to work on government systems and holy hell were they buggy and prone to downtime.
I've complained to bitly several times about spam bots on twitter abusing his services. He told me to fuck off.
If you want to link to an external site, JUST DO IT.
Does somebody not know how to make a normal link? That whole LinkClick.aspx thing is useless at best, but likely an unwelcome way to spy on users. (allowing labor.vermont.gov to know you followed the link... but why do they deserve to know?)
For those who said such an implementation has its legitimate use:
It is stupid. Period.
Write a simple "onclick" javascript, and the webpage can ping back all external links to its own server for whatever statistics purpose. Using redirect links for statistical purpose is NEVER necessary.
Also, waiting for those slow servers to reponse and redirect their redirection link is annoying. Just give me the site I am going to anyway please!
Thanks for getting in touch. We take spam issues very seriously and are constantly working to make spammers' lives miserable. We have blocked this open redirect (and others!) to prevent this from occurring again.
If you ever come across a bitly link being used maliciously, just get in touch via support.bitly.com and we'll take care of it!
Also! Let me know any specific questions you may have!

Disprove any of its points instead of "hit & run downmodding" it -> http://yro.slashdot.org/comments.pl?sid=3199555&cid=41724117

P.S.=> After all - When "the BEST YOU'VE GOT" = unjustifiable downmods? You've got nothing, & since those of you that do that *think* it "hides it"?? Wake up - there's MORE people browsing here @ below the default than there is at the bogus default settings on this forums... So, in other words, face it: YOU FAIL, trolls!

"I use a custom /etc/hosts to block ads... my file gets parsed basically instantly ... So basically, for any modern computer, it has zero visible impact. And even if it took, say, a second to parse, that would be more than offset by the MANY seconds saved by not downloading and rendering ads. I have noticed NO ill effects from running a custom /etc/hosts file for the last several years. And as a matter of fact I DO run http servers on my computers and I've never had an /etc/hosts-related problem... it FUCKING WORKS and makes my life better overall." - by sootman (158191) on Monday July 13 2009, @11:47AM (#28677363)

Oh, I forgot all of our prison spaces are full of people enjoying natural herbs, silly, me, I forgot about such high-priority things like that.
I have one of these scripts on my web site. It isn't there to track if people click the links. It's to allow me to link to shady web sites without Google knowing that I'm linking to shady web sites and penalizing me for doing so. (They are useful for discussion sometimes.) The script itself is blocked by robots.txt, and so Google never sees that there's a redirect that points to the web site since it never makes a request to the script, whereas simply using a nofollow tag would still allow Google to know about the link's existence, even if it doesn't follow the link.
