The wallet stealing is the result of malware which spreads in the usual ways: email attachments, malicious websites, or Trojans hidden in freely distributed software (including rogue versions of Bitcoin utilities).

It is a bad idea to run an unpatched OS from 2001 (XP SP1) or 2002 (XP SP2) while connected directly to the internet..
