How to Choose the Right Cybersecurity Solution REGISTER >
Palo Alto Networks recently published the first edition of its Modern Malware Review [PDF file], which examines new forms of malware found on live enterprise networks. According to the report, traditional anti-virus solutions are failing to identify the majority of malware infecting such networks.
The review states that 94 percent of undetected malware found on networks was delivered via Web browsing or Web proxies, 70 percent of malware left identifiers in its traffic or payload that could be leveraged for detection, and 40 percent of seemingly unique malware is actually repackaged versions of the same code.
"It’s not enough to simply detect malware out there that is evading traditional security," Palo Alto Networks senior research analyst Wade Williamson said in a statement. "Enterprises should come to expect more comprehensive prevention from their vendors."
The Modern Malware Review looks at 26,000 malware samples, collected by Palo Alto Networks' WildFire malware analysis service between October and December of 2012, which had been undetected by their anti-virus solutions.
