(15. Juni 2013) Journalist Christopher Ketcham speculated in a 2008 article that Israeli-linked firms like Verint and Narus could have implanted Trojan spy technology into their devices, providing Israeli intelligence services with a backdoor means of reviewing and analyzing data stored in secure NSA systems. Boaz Guttmann, an Israeli national police cybercrimes investigator, told Ketcham, “Trojan horse espionage is part of the way of life of companies in Israel. It’s a culture of spying.”
