AMS Attack Origin by Country

AMS Attack Origin by Country

This metric assesses the top global countries from which attacks originated that targeted the Americas region in 2011. Note that, because the attacking computer could be controlled remotely, the attacker may be in a different location than the computer being used to mount the attack. For example, an attacker physically located in the Brazil could launch an attack from a compromised system in Australia against a network in Japan.

Methodology

This section measures the top originating countries of attacks that targeted computers in the Americas region in 2011. A network attack is generally considered any malicious activity carried out over a network that has been detected by an intrusion detection system (IDS), intrusion prevention system (IPS), or firewall.

Commentary

  • The United States continues to dominate attacks on the Americas region: In 2011, the United States was the top country of origin for attacks against targets in the Americas region, accounting for half of all attacks detected by Symantec sensors in the region.
  • This result is likely due to the high level of attack activity originating in the United States generally, as it was also the top country for originating Web-attacks globally, with 16.9% of the total. It also ranked second position globally as a source for network attacks, with 33.5% of network attacks originating in the United States.
  • Moreover, the United States ranked first for overall global malicious activity, with 21.1% of the overall total. The United States also ranked first globally for bot-infected computers (12.6%) and in second position for malicious code (13.3%); much of the attack activity targeting countries in the Americas region would have been conducted through these malicious bot networks.
