More on the Santa IM worm



There are a couple of stories out about the Santa IM worm, otherwise known as IM.GiftCom.All. First up Sans has some interesting analysis of it. It appears that it’s being hosted at 69.56.129.67, when run it resolves smtp.girlsontheblock.com to 38.118.133.241 and attempts to open tcp port 53. It renames itself as c:\windows\winrpc.exe and sets up shop as “Windows RPC Services”. They’re saying instead of a worm it should be more accurately termed a bot with replicating capabilities, it is reliant on controls from an outside site. (From their analysis I presume the 69. ip address above?)


The securityfix focuses on the bug today as well. It’s also put in context with the recent uptick in Instant Messenger viruses and a bleak outlook for what lies ahead.

It’s essentially social engineering at it’s best/worst. Social engineering is the oldest and most successful tool that a cracker has and the only way to guard against it is to increase your doubt and increase your willingness to question if it LOOKS like you’ve received a neat link from a friend.
