1. Akamai kicked journalist Brian Krebs' site off its servers after he was hit by a 'record' cyberattack by Paul Szoldra

Well-known security researcher, Brian Krebs, was hit this week by a powerful DDoS attack, among the largest the Internet has ever seen. The attack was over 600 Gbps in size. With the goal of shutting down Krebs’ blog, it’s highly likely the attack was related to Krebs’ recent involvement in the arrest of the two Israelis allegedly running the DDoS-for-hire service, vDOS. Analysis of the attack indicates that the traffic was coming from multiple places rather than a specific global region or a small group of networks. This suggests that a botnet, hacking into a larger number of IoT devices, was involved. Just yesterday, KrebsOnSecurity was taken offline by Akamai, who was hosting the site pro bono.

TechRepublic spoke with DG’s Tim Bandos about cybersecurity in American politics. With the recent rise of political hacks, there are some very real fears as the election date approaches. Both parties have been hit. Bandos explains that parties are often targeted by phishing emails, which, if the victim is duped, gives hackers the opportunity to tap into other computers within the same network. To be best prepared, he recommends that parties invest in the appropriate technologies to better protect themselves and pay attention to how threats evolve.
