An asymmetric cyber attack refers to cyberwarfare that bypasses or sabotages a victim’s strengths while targeting their vulnerabilities. In these types of attacks, the perpetrator has an unfair (or asymmetric) advantage over its opponent and can be impossible to detect. Oftentimes, the aggressor cannot compete in strength or numbers, making this popular among small intelligence groups.
Asymmetric cyber attacks are becoming more common due to their low cost, readily available equipment, and large damage potential. Computer networks are targets of mass destruction as the reliance on digital information becomes more apparent. Entire economies or governments can be taken down via network intrusions, firewall damages, or cyber terrorists.
In order to prevent asymmetric cyber attacks from occuring, companies, governments, or networks should be aware of their own vulnerabilities and create strategies that address potential weak points in those areas. Asymmetric cyber attacks should be treated as a serious threat as the damage can be detrimental, lack boundaries or borders, and cannot be specifically monitored.
Features of an Asymmetric Cyber Attack
- Technology: Cyber attacks are unconventional in that technology requires less planning and lower costs.
- Tactics: The nature of asymmetry makes the plan of attack unfair, uneven, hard to track, and removes any of the victim’s advantages.
- Exploitation: In order to increase odds for success, asymmetric attackers research their victim’s vulnerabilities and create strategies surrounding them.
- Impact: Asymmetric cyber attacks are employed to cause as much damage as possible physically and psychologically, including inflicting distress, shock, and confusion.
Examples of Asymmetric Cyber Attacks
In cybersecurity, an asymmetric attack might involve a perpetrator attacking security measures that have been put in place, such as the firewall or intrusion detection system, by capitalizing on the weakest link. Specific examples of this are:
- The attacks of September 11th, 2001 was unequal in terms of manpower and intelligence, but played on the weaknesses within air transportation and global policies to strike down computer networks as well as cause physical destruction.
- In 2013, the Syrian Electronic Army hacked the Associated Press Twitter account, claiming that President Obama had been injured due to an explosion in the White House. This simple action wreaked havoc as markets and stocks crashed in response to the tweet.
