Internet still targeted by phishers
Though botnets have caused a large volume of junk email in recent months, security researchers are more alarmed at the rise in their level of sophistication, warning that targeted phishing attacks are making their way into corporate email servers.
“They’ve reached a level of sophistication that we usually associate with commercial grade products,” said Mark Sunner, chief security analyst at MessageLabs in New York. “We’ve seen the activity change and now botnets are spammed out in discrete chunks.”
