Two safety researchers have been topped the highest hackers in this 12 months’s Pwn2Own hacking contest after growing and testing a number of excessive profile exploits, together with an assault towards an Amazon Echo.
Amat Cama and Richard Zhu, who make up Group Fluoroacetate, scored $60,000 in bug bounties for his or her integer overflow exploit towards the most recent Amazon Echo Present 5, an Alexa-powered sensible show.

The bug allowed them to take “full management” of the gadget if linked to a malicious Wi-Fi hotspot, mentioned Brian Gorenc, director of Development Micro’s Zero Day Initiative, which placed on the Pwn2Own contest.
The researchers examined their exploits in a radio-frequency shielding enclosure to forestall any outdoors interference.
“This patch hole was a typical think about most of the IoT gadgets compromised in the course of the contest,” Gorenc advised TechCrunch.
An integer overflow bug occurs when a mathematical operation tries to create a quantity however has no house for it in its reminiscence, inflicting the quantity to overflow outdoors of its allotted reminiscence. That may have safety implications for the gadget.
When reached, Amazon mentioned it was “investigating this analysis and shall be taking applicable steps to guard our gadgets primarily based on our investigation,” however didn’t say what measures it will take to repair the vulnerabilities — or when.
