Yahoo has apparently found yet another way to assist spammers.
As if longstanding abuses of Yahoo Groups weren’t enough for the spammed masses to suffer though, their blog site, Yahoo Pulse, is now making life easier and more productive for spammers as well.
The latest emails being spewed throughout the Internet have long and convoluted Subject lines (in an attempt to evade spam filtering) that allude to online sales of medications, such as:
Subject: extraordinary tablets tendered for superb way of life
Subject: supplying exceptional capsule brands for lots of years
Subject: web outlet tremendously suggested for pills purchases
Microsoft, itself a massive spam-enabler, is sending the vast majority of these emails (if not all of them) through hijacked Hotmail accounts abusing it’s mail servers. While the From addresses may or may not be legitimate Hotmail accounts:
From: Boyd Owenby <firstname.lastname@example.org>
From: Stroum Elliff <email@example.com>
From: Elphonte Stutz <firstname.lastname@example.org>
The actual sending mails servers most certainly are Microsoft’s:
from col0-omc4-s15.col0.hotmail.com (22.214.171.124)
from col0-omc3-s9.col0.hotmail.com (126.96.36.199)
from snt0-omc1-s27.snt0.hotmail.com ([188.8.131.52])
The messages themselves, like the subject lines, promote the sales of online medications in the vaguest possible terms, and in each case link to a Yahoo Pulse blog that exists solely for the purpose of redirecting to the spammer’s e-commerce site:
We are truly concerned for our customers’ welfare. Every capsule product we market has underwent rigid quality check-ups. This assures you that the goods are secure to use. Our http://pulse.yahoo.com/_WDSMBZ3ZJOQV5GOL67KG3QZI6M/blog is staying put for your repurchases.
We love your all-positive statements.
It moves us to give out more extraordinary capsule brands. Actually, recent products have already been launched at present. Upcoming orders can still be placed at the same http://pulse.yahoo.com/_65JOSV7Y3JLUVL2QZMIRLVF5AY/blog
If you visit the Yahoo Pulse group you’ll be presented with a large Spam Advertisement such as:
The graphic on the blog is actually hosted externally by Microsoft’s LiveFileStore.com site, another longstanding tool used by spammers with little or no apparently enforcement from Microsoft. See any of these:
Ultimately, these spams will eventually direct you to the spammer’s actual e-commerce site where you can order what may or may not be food coloring and chalk in tablet form.
To further remove themselves form the spam and to try and make filtering less effective, the initial links will typically redirect to the actual spam sites. For instance:
From the spammers perspective, all of this takes a bit of effort but is well worth it. By using free tools provided by Microsoft and Yahoo they can:
- Send spam through Microsoft
- Redirect the recipient to a Yahoo Pulse site
- Display a spam image advertisement courtesy of Microsoft
They can do all of this without cost and while using Microsoft and Yahoo to shield their own networks from spam filters.
Of course, this only works for the spammer because both Yahoo and Microsoft have lax, ineffective or non-existent review and enforcement of their systems to prevent these abuses.
