Website Attack Attempts Via Vegas Rose During Black Hat, DEF CON
On a “normal” day, an average of 20 malicious web traffic events originating in Las Vegas hit Imperva’s security customers. During Black Hat USA and DEF CON earlier this month, that number jumped more than 100 times the volume, according to a snapshot of data the firm compiled.
Barry Shteiman, director of security strategy at Imperva, was curious about just how much more malicious activity really does occur during big hacker-heavy conferences like Black Hat and DEF CON, so he measured the malicious traffic coming from Las Vegas the week of the two major shows and found the number reached a high of 2,612 web attacks aimed at its customers.
“I decided to test for attack traffic originating in Las Vegas during BlackHat and Defcon, and a month prior to that in order to correlate to baseline. In order to do that, we collected all of the security events during that time period from our Community Defense system, mapped Geo IPs for Nevada state, and Las Vegas specifically, then we queried the Community Defense data set for all source IPs that were in the US,” Shteiman wrote in a blog post today. “Finally, we summarized by date and where the city itself is Las Vegas.”
He says there also was a spike in attack volume during the NAACP’s conference in Vegas in July. That means that “either that a large crowd in a conference scale event may cause a growth in attack volume due to malware on computers, or attackers are attending the conference and performing their attacks from there,” he says.
With Black Hat and DEF CON, an increase in attack traffic wouldn’t be too surprising in general. But the jump he spotted was intriguing: “They have some of the brightest security/hacking minds in the world attending. Those guys who read every link before they click, run custom operating systems in cases and are generally very aware to security and thereforeare less likely to be drive-by victims of hacking — for that reason, seeing numbers that high is more substantial at a hacker conference than in other conferences,” he says.
The attack volume rose at the start of Black Hat, dropped toward the end, and then began to increase at the start of DEF CON, he says. “A day after everything ends, the numbers are back to norm,” he says.
Shteiman warns that the data is more of an “interesting snapshot” than a true trend, but it makes you think. His full post with data and graphics is here.
