According to Symantec, the group behind the Mac Flashback malware was making roughly $10,000 per day through the use of the botnet created by the malware. The botnet had spread to nearly 700,000 computers at its peak, and those computers were generating revenue for those in control of the system. The Mac Flashback exploit was loaded into Chrome, Firefox, and Safari and targeted searches done through Google. The malware allowed the search to be hijacked and redirected to a different page, depriving Google of the ad revenue and instead putting it into the pockets of the hackers. Symantec also noted that Apple had a particularly slow response time in fixing the exploit, waiting nearly two months after the fix had been issued by Oracle to release it to users.
