Microsoft Experimental Software Updates?

Posted: Thursday, October 09, 2008

As most of you know, Microsoft doesn’t distribute it’s software updates via e-mail. Although this recently received bogus message would try to convince us differently. It claims to be from Steve Lipner who actually is a Director of Microsoft’s security engineering team. It even explains that the reason for the update being delivered via e-mail is to help prevent malicious software and that this is a new experimental feature. This is a malicious application so delete it immediately! Perhaps it’s just a coincidence but it popped up the same day as Microsoft’s official advance notification for the October security bulletin. From a social engineering viewpoint it could help lend credibility to the attack. If a person used a search engine they could easily find the announcement of an upcoming update. On the other hand they may just find our blog and warning. I should point out that this isn’t the […]

Post #3 on Why Spam Filters Suck “trickle blog” series

Once Promising Proposals for a Final Ultimate Solution to the Spam Problem (FUSSP) “Two years from now, spam will be solved.” That was Bill Gates’ famous pronouncement back in 2004. Microsoft, Yahoo and the open source community devised two techniques that they believed would eradicate spam. The first was sender authentication, which allowed email senders to provide a list of the servers permitted to send email for users within their domain. The idea was that sender authentication would eliminate spammers spoofing legitimate email addresses, and allow for the creation of a permanent, ironclad white list of trustworthy domains that never send spam, thus allowing recipients to simply block everything not on the white list and end spam forever. Another idea pitched in 2004 was the computational challenge. Senders would, upon connecting to a receiving email server, have to spend considerable CPU cycles computing the answer to a mathematical challenge provided […]

E-mail from Bill Gates

This morning I checked an old Hotmail account and I was surprised to see an e-mail from Bill Gates. The From header was “Bill Gates ([email protected])” which was a little surprising. I would have thought that Bill would be sending it from a Microsoft or at least a Hotmail address and not a competitor such as Yahoo. I put that thought at the back of my mind since I was excited to see why he was e-mailing me. Here’s the message I received: The content of the message was in French. I put this down to the fact that Microsoft is based in Redmond, Washington which borders us here in Canada and perhaps some French Canadian influence had started to spread across the border in the USA? After reading the e-mail, I discovered I was a winner of the “BILL GATES FOUNDATION LOTTERY FOR INTERNET EXPANSION IN AFRICA”. I realized […]

IBM on Spam and Phishing

IBM published their mid-year report for 2007 with details related to spam and phishing attacks. It’s quite a long report so I picked out some of the points I found interesting. There’s a synergy between spam and virus activity since a wide spread virus has the ability to turn hundreds of thousands of personal computers into spam spewing zombies. The virus writers exploit vulnerabilities to gain control of a machine. IBM commented that “more than half of the vulnerabilities in the first half of 2007 would allow an attacker to gain access to the host after successful exploitation”. An interesting point is that the top 3 vulnerability vendors in the first half of 2007 were Microsoft, Apple and Oracle. As part of the spam analysis they looked at the average byte size of spam. This of course correlates with the surge in attachment spam over the past couple of years […]

Google Apps are Taking Off?

Some of you may be familiar with MailChannels’ “PingedIn” service. Every night, we survey the mail servers of approximately half a million companies worldwide, using a proprietary algorithm to determine the kind of email server software they are using to receive email. Recently I was reviewing historical data stretching back to mid-summer, when I noticed a strong trend: The lime green line shows that there has been a 50% increase in the number of companies using Google to host their email. This is a really impressive rate of growth in what has been a fairly stagnant industry for the past few years. Other interesting observations: The decline of software: more and more companies are outsourcing their edge email solution to someone else. The only exception we found to this rule was MXLogic, who appear to have lost about 5% of their customers since mid-summer (according to our data — please […]
