Sendmail. Tcpdump. OpenSSH. In addition to being highly useful software products, the Internet sites used to distribute each of these tools were compromised by attackers over the last few years.

With control of the sites, the bad guys replaced the downloadable installation package for each tool with a "Trojanized" version that included a backdoor bundled in the package. By placing their evil versions on the normal, trusted sites enterprises relied on to download their tools, the bad guys had hit upon the ideal mechanism to propagate their malicious code -- duping systems administrators to take the bait and install their wares for them.

Of course Microsoft had its site compromised and source code stolen in the last few years too. Who knows what else happened or if other such compromises have ever taken place.

Whose word do we take, theirs. Would they lie to protect a $30+ billion company, when it's something as serious as 10s (100s?) of millions of customers of course not....
Despite searching I have been unable to find the incident where MS distributed some of its software on infected discs. My memory was that it was one of their Windows versions. Anyone have a link?
I found these pretty quickly:

These appear to describe a number of cases of MSFT shipping infected software, and a case of a trojan allowing someone to steal Windows NT and 2000 source code, later posting it to the world wide web.

MSFT has been compromised to the point of people copying Windows source, and MSFT has distributed "pre-infected" CDs more than once.

It doesn't look to me like back-doored distributions have ever made it out, unless you count the "NSAKEY": http://en.wikipedia.org/wiki/NSAKEY
