200,000 Cisco network switches worldwide were hacked Friday, affecting large internet service providers and data centers across the world. The impact of the attack, including data loss, is not yet clear who carried out the attack. The hackers apparently reset the targeted devices, making them unavailable for reconfiguration and leaving a message that reads: “Do not mess with our election” The attack apparently exploited a vulnerability in software called Cisco Smart Install Client, which allows hackers to run arbitrary code on the vulnerable switches.”]
