Bad month for Microsoft's efforts
It's been a bad month for Microsoft's efforts to
promote their visions of trustworthiness and authentication in Internet
commerce.
Just as the ground began to crumble beneath Microsoft's "Sender
ID" email authentication proposal, it was discovered that the
Redmond, Wa.-based software giant was considering acquiring Claria,
one of the world's most notorious adware and spyware companies.
Let's look first at the email authentication wars. As I've discussed
previously, the battle over email authentication has been raging
for several years. Among the many proposals being considered by
the email industry and Internet standards community is Microsoft's
Sender ID and its closely related cousin, the "Sender Permitted
From" or SPF standard.
Both SPF and Sender ID use text records entered into a domain's
DNS entry that define what IP addresses should be permitted to send
email for that domain. These definitions embedded in the sender's
DNS records are then queried and parsed by the receiving server
to determine whether to accept or reject a particular piece of email.
As I reported back in October, Microsoft's Sender ID proposal became
the subject of much scorn when it was discovered that, at the same
time they were promoting Sender ID as a global standard, they were
trying to patent the technology surrounding Sender ID.
In the intervening months, numerous major service providers participating
in the Messaging Anti-Abuse Working Group, an industry consortium
that is promoting the development of new email authentication standards,
have continued to test Sender ID. Their recently released findings
are not good news for Microsoft.
According to the technical committee's white paper :
"At best, SPF and Sender ID are comparable to a license plate
issued by a foreign country: they show that the vehicle is permitted
to drive in that country, but make no indication as to whether that
country's regulations are similar to yours - and we can only assume
that the driver inside is permitted to use that vehicle."
But the committee went on to explain that along with these dubious
benefits, there were some significant downsides to implementing
Sender ID.
These include:
* Forwarded or re-sent mail will fail authentication
without changing email systems to re-write return addresses and
add new headers;
* Those sites publishing authentication records
must ensure that their records permit mail from all possible points
of origination or risk having legitimate email mislabeled as spam;
* This method of authentication does not provide
protection against forgery of the most common user-visible mail
headers;
* Receivers must be aware that performing some
checks in accordance with Sender ID and SPF may yield inaccurate
authentication results due to misinterpretation of the Sender's
authorization., and
* If your operation provides email services to
roaming users, you may need to forge or add certain headers in order
to ensure
successful authentication.
As a result, several major service providers have
removed their Sender ID and SPF statements from their DNS records
in order to avoid potential confusion and lost email.
But just as the industry is backing away from Sender
ID, Microsoft rekindled fears of monopolistic bullying tactics by
unilaterally declaring that all email sent to MSN and Hotmail would
be scanned for Sender ID compliance. Resistance is futile. If your
company's email doesn't pass a patent-pending Sender ID check, it
might be labeled as spam and consigned to the dreaded Spam folder.
Just as the world was trying to digest what Microsoft
was attempting to shove down its collective throat, word leaked
out that Microsoft was in talks to buy Claria, formerly known as
Gator -- one of the world's most notorious peddlers of spyware and
adware -- which I will call malware hereafter for the sake of brevity.
According to several news reports, Microsoft has
been eager to compete in the online advertising markets dominated
by companies like Yahoo and Google. Experts suggest that buying
Claria would give Microsoft a jumpstart in the market because of
Claria advertising network consisting of more than 40 million souls
who receive Claria annoying pop-up ads.
As one commentator wrote, this move "underscores
just how eager Microsoft is to catch up with Google, the search
and advertising giant."
Eager? How about desperate?
In my opinion, picking up Claria for its advertising
network is like buying a former nuclear bomb testing site because
the lack of anything standing gives you such great views in all
directions. Just don't touch anything, ignore the three-headed rabbits
populating the poisoned ground, and you'll be fine.
There are plenty of other ad networks out there,
most of which got to be successful without engaging in deceptive,
unfair, and lawsuit-provoking activities.
Some might say Microsoft and Claria have been unwittingly
working together for a long time. Claria advertising reach is directly
tied to its years of distributing malware and long history of its
paid "affiliates" taking advantage of security holes in
Microsoft's operating system to install the software surreptitiously
and without end-users permission.
In its defense, Claria claims to be migrating its
business model to one focused on more legitimate forms of business.
But like the Gotti family and their garbage hauling business, I
have a feeling that it is going to take them some time to stop living
off their other gigs.
More recent reports suggest that an acquisition
of Claria is never going to happen because Claria reputation is
too tarnished for even Microsoft's tastes. But that didn't stop
Microsoft from giving Claria a pre-engagement gift just last week
-- downgraded threat rating in Microsoft's anti-spyware utility!
According to Eric Howes of SpywareWarrior.com:
"Several sources have now confirmed that Microsoft downgraded
its detections of Claria's adware products in the latest update
(#5731) to Microsoft AntiSpyware released today. Where Microsoft
AntiSpyware used to detect Claria's products and present users with
a Recommended Action of 'Quarantine, following today's update Microsoft
AntiSpyware now presents users with a Recommended Action of 'Ignore[.]
Users can still change the action to "Quarantine" or "Remove."
In the end, though, this is nothing new. As I've
noted before , other security software makers have gone soft on
malware. Microsoft's is only the most recent, and to my way of thinking,
the most unprincipled and morally corrupt.
So the next time you hear pronouncements from Microsoft
about their efforts to make your computing experiences safer and
more secure, a deeper look may suggest that Microsoft's effort to
be part of the solution includes taking a bigger stake in the problem.
