With revenue growth of 35%, PayPal was one of the stars of eBay Inc.'s [EBAY] fourth-quarter earnings last week. On Monday, the online auctioneer said its Internet payment subsidiary would acquire Fraud Sciences Corp., a privately held Israeli company with expertise in online risk tools, for $169 million in cash.

We'd link to the Fraud Sciences Web site, but it's already been hijacked by eBay. But what we can tell you is that Fraud Sciences' technology helps differentiate between real and fraudulent transactions and will be used by eBay to accelerate development of new fraud detection tools. The company raised $11 million in October of last year from Redpoint Ventures and BRM Capital. - David Shabelman
