AIM, ICQ, Gtalk, Jabber, Yahoo Messenger, MSN: Verbindungen zu all diesen IM-Systemen via ein Browserfenster - und also auch überall dort, wo der Chef oder die Technik es nicht erlaubt: meebo.com, bisher eine 3-Kopf-Firma. Respekt! Allerdings hat <a href=forum.meebo.com target=_blank>dieser Forumseintrag in der Diskussion, ob meebo zu traun ist oder nicht, durchaus was:

Aside from all the encryption issues, passport issues, and legal issues, meebo apparently works like this: user enters uid & pwd -> browser encrypts pwd -> meebo decrypts password and enters it into a gaim instance -> gaim communicates with IM hosts Theoretically, a single line of code snuck into meebo could kick the decrypted uid & pwd out to a file or to an internet host. This line of code could be put in by anyone with access to the meebo codebase -- meebo developers, or anyone else that has gained access to the codebase via the internet. The uids and pwds are only as secure as meebo's codebase, firewall, RAS portals, SSH accounts, lighthttpd server, etc... If a vulnerability exists for lighthttpd, which is used by meebo, and meebo doesn't patch for it, they're vulnerable. They may have (and probably do have) the best intentions in the world. But good intentions don't secure websites. If you're using meebo with, for instance, a yahoo uid & pwd that has email enabled, and you've used that email address as the contact email anywhere (such as ebay or paypal), then you're really rolling the dice. You have been warned. However, I would have no reservations at all using meebo with a yahoo account that has solely been setup for the purpose of IM via meebo. That way the worst consequence is that somebody may be watching your messages.

meebo startete im September. Seit einigen Tagen gibt's auch noch gtalkr. Das ist ein Flash-basiertes Interface zu Deinem GoogleTalk-Account. Die Sicherheitsfrage stellt sich da allerdings genau gleich. Übergebe ich einem Dritten mein "Username / Passwort"-Paar für einen Account, "nur" damit ich einen Chatdienst im Browser nutzen kann? Muss ich sicherheitshalber extra einen neuen AIM/Gtalk/Jabber/etc.-Account anlegen, den ich NUR für den browserbasierten Dienst nutze? Offene Fragen.
