Cybercriminals ditching mass spam for targeted attacks.
Key Findings - Email Attacks.
* Returns from mass email-based attacks declined by more than 50 percent from US$1.1 billion in June 2010 to $500 million in June 2011.
* Mass spam volumes plummeted from 300 billion daily spam messages to just 40 billion between June 2010 and June 2011.
* There is an increase in spearphishing and personalised scams and malicious attacks.
* Spearphishing attacks have increased threefold, while scams and malicious attacks have increased fourfold
The overall cost of targeted attacks to organisations worldwide is $1.29 billion annually.
Like almost all types of cybercrime exploits, the success of targeted attacks relies on technical holes and the all-too human tendency to misplace trust.
Targeted attacks are the most elusive threat to protect against and have the potential to deliver the most potent negative impact. Very low in volume, they focus on a specific individual or group under cover of anonymity provided by specialised botnet distribution channels. Typically, they rely on malware or APTs (Advanced Persistent Threats) to harvest desired data over a period of time. An example of a targeted attack is the infamous Stuxnet worm, which had the potential to severely disrupt industrial computing systems and could traverse non-networked systems, thus placing at risk even systems unconnected to networks or the Internet.
