Gardner Recommends to Replace or Augment Passport
by Arie Slob
Hello Windows users,
Market research group Gartner last week issued an advisory titled: Security Flaw Shows Microsoft Passport Identities Can't Be Trusted, advising that financial institutions, credit card issuers, retailers and other enterprises that use Microsoft Passport for any meaningful business purpose immediately break all Passport connections until at least November 2003, until Microsoft can prove that its security is adequate. Or invest in an additional, more secure form of authentication for all issued Passport identities.
In addition Gardner advised those institutions to contact all their customers who use Passport and make them aware of Microsoft's recommendations for Passport account holders.
This advisory comes after the latest security flaw that hit Microsoft's Passport service on the 7th May. The flaw, in Passport's password recovery mechanism, could have allowed an attacker to change the password on any account to which the user name is known. The flaw was disclosed Wednesday evening on the security mailing list Full Disclosure.
While Microsoft fixed this particular vulnerability within a day, Gartner analysts say that "as with any piece of software with serious security flaws, more vulnerabilities will likely surface in Passport" and that "Enterprises considering Passport services should delay adoption until at least November 2003 or until Microsoft has completed a thorough security review of Passport, including outside reviewers."
Kaspersky Labs: IE users "defenseless" to Trojan attack
According to Kaspersky Labs, an international data security software developer, Microsoft hasn't reacted to its calls to issue a patch for the StartPage Trojan, which exploits vulnerability in Internet Explorer 5.0
StartPage is a classic Trojan - it is sent to victim addresses directly from the author and does not have an automatic send function. The first mass mailing to several hundred thousand addresses was registered in Russia on May 20.
The StartPage program is a Zip-archive that contains two files - one HTML file and one EXE file. Upon opening the HTML file the StartPage code is launched and proceeds to exploit the Internet Explorer security system vulnerability known as "Exploit.SelfExecHtml". It then proceeds to clandestinely launch the EXE file carrying the Trojan program.
"It is hard to call this program dangerous, its collateral effects include only the altering of an old Internet Explorer page. Still, StartPage has set a precedent with its usage of a vulnerability for which there is not yet a patch", commented Eugene Kaspersky, Head of Anti-virus Research at Kaspersky Labs.
According to Kaspersky Labs statistics, over 85% of virus incidences in 2002 were caused by malicious programs such as 'Klez' and 'Lentin' that exploit the IFRAME Internet Explorer vulnerability, which was discovered over two years ago, and thus users have had plenty of time to install the patch and protect themselves against any similar virus appearing in the future.
"With StartPage we are dealing with an open vulnerability. Users can protect themselves with anti-virus software, but not all of them have strong heuristic technology to protect against future viruses", continued Eugene Kaspersky. "A new vulnerability has been exposed that may incite the creation of a multitude of new malware that could lead to new epidemics of a global scale."
I think that a possible explanation for Microsoft's apparent reluctance to issue a patch is that Microsoft no longer supports Internet Explorer 5.0, which it replaced with Internet Explorer 5.01 and 5.5, both of which are in most cases entering their "Extended" support phase (or getting close to their End Of Life) according to the Microsoft Web site.
