The axiom “Quality, not quantity” has been adopted by everyone from stock pickers to those trying to successfully navigate the online dating scene. Now cybercriminals are also putting this philosophy to practice.
The fundamental shift away from mass spam attacks to more targeted threats with potentially bigger payoffs is top of mind to me. This trend is detailed in a new report by Cisco’s Security Intelligence Operation (SIO).
Specifically on the issue of spam, Cisco’s research reveals that mass spam volumes dropped from 300 billion daily spam messages to 40 billion between June 2010 and June 2011. Although 40 billion is still a huge number, signifying that spam is still an issue, the trend that’s most alarming is the threefold increase in spearphishing and the fourfold increase in personalized scams and malicious attacks such as malware.
