New Cisco Report Shows Traditional Mass Spam Volumes Plummeting as Cybercriminals Turn to More Lucrative, Pinpointed Attacks
In the complex and ever-changing landscape of online crime, cybercriminals have made a fundamental shift in strategy, abandoning traditional mass spam attacks in favor of personalized attacks with a greater financial impact on targeted organizations, according to a new security report from Cisco. Research conducted by Cisco Security Intelligence Operations shows the trend toward increased targeted attacks featuring highly customized threats containing malware that are directed at a specific user or group of users for intellectual property theft.
Key Findings - Email Attacks: This Time, It's Personal
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 specialized 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.
Spearphishing attacks, though more costly to mount and lower in volume than mass spam attacks, also pose serious consequences for today's enterprises. Many spearphishing attacks ultimately lead to financial theft, making them both highly dangerous to victims and highly valuable to cybercriminals. Spearphishing campaigns, which are a highly customized evolution of the traditional mass attack technique of phishing, can net 10 times the profit of a mass attack.
The global study focuses on perspectives from 361 information technology professionals from 50 countries and was compiled by Cisco Security Intelligence Operations, which provides real-time threat intelligence to help Cisco stay ahead of the latest cyber threats. Cisco SIO is the world's largest cloud-based security ecosystem, using SensorBase data of almost 1 million live data feeds from deployed Cisco email, Web, firewall and intrusion prevention system (IPS) solutions.
