Microsoft Researchers Slash Skype Fraud By 68%

mask.of.sanity writes "Life could become more difficult for fraudsters on Skype thanks to new research by Microsoft boffins that promises to cut down on fake accounts across the platform. The research (PDF) combined information from diverse sources including a user's profile, activities, and social connections into a supervised machine learning environment that could automate the presently manual tasks of fraud detection. The results show the framework boosted fraud detection rates for particular account types by 68 per cent with a 5 per cent false positive rate."

So let me get this straight...

Your new filter works better than today's filter...against today's spam

But today's spam is designed to circumvent today's filter, and spammers will change their techniques as soon as you switch to the new filter.

This is the classic Antivirus problem, where new and unusual AV programs get great ratings until they become popular and virus developers start coding with them in mind.

And now you've also published how your new filter works, to make it even easier for spammers to circumvent your new filter. Great.
