You are looking at the HoneyMap, a real-time world map which visualizes attacks captured by honeypots of the Honeynet Project. Red markers on the map represent attackers, yellow markers are targets (honeypot sensors).
This project is highly experimental and should be considered a BETA version. So far, current Chrome and Firefox browsers should work fine. Opera, Safari and Internet Explorer probably wont work completely. If you identify bugs or have feature requests, please let us know.
Yes, you are looking at real attacks which are captured by our honeypot sensors. Those sensors emulate vulnerable systems and record incoming attacks.
