There have been times over the last two months when Golan Ben-Oni has felt like a voice in the wilderness.
On April 29, someone hit his employer, IDT Corporation, with two cyberweapons that had been stolen from the National Security Agency. Mr. Ben-Oni, the global chief information officer at IDT, was able to fend them off, but the attack left him distraught.
In 22 years of dealing with hackers of every sort, he had never seen anything like it. Who was behind it? How did they evade all of his defenses? How many others had been attacked but did not know it?
Since then, Mr. Ben-Oni has been sounding alarm bells, calling anyone who will listen at the White House, the Federal Bureau of Investigation, the New Jersey attorney general’s office and the top cybersecurity companies in the country to warn them about an attack that may still be invisibly striking victims undetected around the world.
