Re: Are Internet Cafes safe ?

How can you trust someone else's system to protect your data?  You can't!

Subject: [Intrusions] Are Internet Cafes safe ?



Let me rephrase that.

Is it possible to safely use a PC at an Internet Cafe to login to
somewhere ? Millions of travellers want to know (or they ought to!)

(We are tracking an incident where we suspect a trojaned PuTTY SSH
client, or a keystroke logger, was used to capture passwords in a cafe).

So the question is, if you aren't allowed to boot your own system off a
CD or memory stick, or read in long keys off media, how can you use a
system where you can't trust the keyboard ?

One-time-pad tokens would work, but only to protect the initial login,
not the text or any further logins made from the shell account.

Ideas ? What are other people doing ?

(I tried to post this on Bugtraq but I guess it was considered off-topic
and went in the bit bucket. I thought they used to at least send a
rejection message ... it's probably off-topic here, but I can't think
of a more appropriate forum offhand)
