I would like to know if it is possible for software to eavesdrop on my skype conversations. Key loggers needs to be installed on my computer, and I know that the my company does not have any software on my computer that I am not aware of (I installed the software myself).

I know the other computer has Kaseya on. Kaseya monitors windows updates and other things.

Would Kaseya or any other software on the recipient's pc be able to eavesdrop on our skype conversation (my messages) without letting the user know?

Skype doesn't specify how they apply their encryption (other than it being AES), so there is no reason to assume it is more secure than letter substitutions. Furthermore, they are known to decrypt data on their servers (no end to end encryption) if governments ask for it.

Any software installed at either client computer can in theory listen in on your conversations, although I've never heard of this "Kaseya".

However, I would be far more vary of hidden microphones at my desk than of sophisticated software attacks. Also remember that common keyboards and monitors (both crt and lcd) can be wirelessly eavesdropped from several meters away with low-cost equipment.

I you really need to keep something secret, you should use some peer-reviewed cryptographic software (gnupg is commonly used) with large keys encrypted with high-entropy passphrases, and make sure decrypted text or data is never stored on permanent media.

This is the company I work for. Kaseya doesn't seem to be the type of software that was made to decrypt messages. I doubt my company would want to eavesdrop using microphones. Thanks for suggestion on gnupg. – Nightwolf Feb 1 at 6:52

All Skype-to-Skype voice, video, and instant message conversations are encrypted. This protects you from potential eavesdropping by malicious users.

That should mean that without a third party seeing the screen, the only way is to use a keylogger.

All because something is encrypted, it doesn't mean that it cannot be read. Given access to your network card (through tools like wireshark) and X amount of time to decrypt the data, it is possible to decrypt data. Encryption makes it harder, not impossible. – Stuart Blackler Jan 31 at 12:30
@StuartBlackler: Thanks for comment. This is the company I work for and I seriously doubt their hacking skills. If a software does not allow them to do it in a simple manner the software is easily used for malicious intent then I doubt they will use it. – Nightwolf Feb 1 at 6:44
