CTO of NewAE Technology, Colin O’Flynn, and Eyal Ronen, an Israeli student, shared a presentation and a video of hacking office building lights. Later, they even hacked the light at the conference.

Social media addicts, take care!

Very often what you see on social media might not be what it seems. Using deceptive phishing links, hackers easily target social media users to steal their personal information and money.

The same concept was demonstrated by ZeroFOX data scientists Philip Tully and John Seymour. They build a bot that targetted social media users, collected information regarding their interests and penetrated the feed with a catered message. This Twitter bot was a success with a click rate as high as 60%.
