"Sharov believes that Apple’s attempt to shut down its monitoring server was an honest mistake."
"In Apple’s defense, it may not have recognized Dr. Web as a credible security firm when the company contacted Apple earlier this month–I hadn’t heard of the firm either until its discovery and analysis of the Flashback botnet."
It looks like Apple wasn't the only one surprised by this:
"But the better-known security firm Kaspersky confirmed Dr. Web’s findings on Friday. A Kaspersky representative said it hadn’t contacted Apple with its findings and hadn’t had any direct communication with the company, and Kaspersky researcher Kurt Baumgartner wrote in a statement that 'from what we’ve seen, Apple is taking appropriate action by working with the larger internet security community to shut down the Flashfake [also known as Flashback] C2 domains. Apple works vigorously to protect its brand and wants to rectify this.'"
