Secure Remote Services


Today we received an request about secure applications for remote access on windows machines. While the questions were related to Remote Desktop x <A commercial vendor application>, the following advices are from a quick opinions from the handlers:



- Restrict access to the remote service application

- Restrict the resources in the remote machine to remote users

- Some VNC variants will add strong authentication, as secureVNC (

- Tunnel the remote service application, using something like ssh or VPN

MyDoom and IFRAME

On Marcus Sachs´s diary from yesterday, he mentioned the IE exploit email, but not explicitly a MyDoom variant. The reason is that he choose not to refer to MyDoom since there was some argument yesterday as to whether this was really another strain of MyDoom or something brand
new.


Also in this topic, bleedingsnort website released snort signatures for both .ah and .ai variants. Although it may not detect variants with minor changes, it may be worthwhile to try to find those in your network.
