Malicious Shortened URLs : Rising Threat

1.     Internet today is all but a minefield of boogies,traps and malware.....every day so many threats are born....though most of them die but still a huge percent of them survive the security walls and become stronger by time as they are able to remain live and acvtive.In recent times shortened URLs have become popular amongst users (including me...:-) to conserve the typing space like in microblogging sites viz twitter etc.So typically a naive(???),prone user who submits his long URL to a site to get a shortened URL receives a second,specially coded shortened URL that redirects to the original URL.So here lies the weak hole that is most of the times exploitable by the attacker...because the actual destination URL is hidden in it....so going by the looks...there is nothing to worry...but it is the redirection that is a cause of worry...it may be right or may be redirecting to a malicious link....!!!!so when some one uses a free URL shortener ,he does not have control over that shortened link. And, should something happen to the provider of that URL shortener, then he risks redirecting ALL of shortened links elsewhere!!!

2.  We all know that clicking links is pretty tempting....so it is just a matter of one redirected malicious link click that makes the difference....so whats the solution????...actually companies like Facebook,Gmail, SBI, Paypal ,twitter etc are offering users the option of persistent SSL encryption and authentication across all the pages of their services including the login and all accessible pages.....but this does not stand good for all...for these sites also..it is optional to vide the settings for accessing....

Win32.Hlux : January 2011 " King of worms"

1.   Email-Worm.Win32.Hlux was talk of the E-town in January across the webosphere. This mail worm spreads via emails containing malicious links that prompt users to install a bogus Flash Player, supposedly to view an e-card. The link leads to a dialog window that asks if the user agrees to download a file. Irrespective of the response, the worm sets about to penetrate the system. In addition to propagating via email, Hlux also has bot functionality and adds infected computers to a botnet before connecting to its command center and executing its commands, which are primarily directed at sending pharmaceutical spam.

2.   Kaspersky Lab also detected a Trojan dropper masquerading as a key generator for the company's products. The old adage "There's no such thing as a free lunch" is particularly fitting here as the dropper goes on to install and launch two malicious programs. One of them steals program registration data and passwords for online games. The second is a backdoor that also has keylogger functionality.

3.   Kaspersky Lab also found the mass distribution of malicious short links on Twitter. After a number of redirects, the attention-grabbing links led users to a page promoting a rogue AV program.

4.   Apart from these two hardworkers(?????..i mean mal hardworkers) in january,the other shining star in the E-crime world is AdWare.Win32.WhiteSmoke.a which if clicked, will download a program that demands payment to rectify errors it supposedly detects on the system.
