In the middle of a post about Microsoft’s new Windows Live Messenger service, Dwight Silverman’s guest blogger Jim Thompson writes:
At home I don’t install IM software both because I have little need for it and because I see it as just another source of viruses and other malware.
One could make the same argument about e-mail, I suppose. Or networking. Or mobile phones.
And can anyone point me to the treasure trove of “viruses and other malware” that sneak in via IM products? Because I’m sure not seeing them out there in the real world. Googling the subject turns up a flurry of scare-mongering articles from 2003, 2004, and early 2005, all of which report on the alarming increase in IM viruses and predict that this year will be the year that IM-borne viruses finally take off. Oh, wait! Here’s yet another scare-mongering article from June 2006 – “a 500 per cent increase in IM attacks during last month alone.” Details? Bah! Who needs details?
I would take all these articles much more seriously except for the fact that every single one just happens to tout a new study from a security software company that just coincidentally happens to have the product that will solve this alarming new problem.
Nice racket.
Update: In the comments, Jim Thompson responds:
Look at my statement this way, Ed: IF I had a serious need for IM software THEN it would be worth dealing with the malware risk. In the case of networking and email, the need if the technology is worth the trouble of dealing with malware.
Maybe I’ve been duped by the security folks, but tell me: isn’t it true that IM can be used to send executables? And I know for a fact that *any* executable can contain a virus, rootkit, or trojan horse. Given that I’m not that familiar with IM software (something that I mention in the post) and that IM would be used mainly by my young daughters (something I didn’t mention), isn’t it prudent to simply not give malware another route onto my systems?
My reply:
There are three completely separate issues at work here, and conflating them just confuses the discussion.
1. If you don’t need a particular class of software, don’t install it. I’ve been preaching that gospel for years, and it’s still true. Any program can introduce possible security and stability problems, so why install something you don’t need? This argument isn’t unique to IM software.
2. Your kids are the ones who might use this software? Of course you should look carefully at it before installing it. Not just because they can download executables, but because they can communicate with strangers. In my opinion, this is a parenting issue, not a computer security question.
3. Can IM be used to send executable files? Well, yes, as can e-mail. In the case of Windows Live Messenger, there is a fairly easy to access setting that allows you to automatically block ALL known unsafe attachments, including types that aren’t normally considered executable. In addition, the software has an integrated and apparently free virus scanner.
I agree that you should evaluate any Internet-facing software carefully before installing it, but falling for the security industry’s fear tactics is a bad starting point for that evaluation process.
Update 2: Jim has posted an excellent follow-up here.
