He dismissed the latest threats and said they would do nothing to change Facebook's and Twitter's efforts.
"However, it would be a whole different ballgame if there is an organized physical attack on either the companies or their personnel," said Olds. "A successful attack might, unfortunately, change things considerably. But I think that both companies have probably beefed up security in light of these threats, so pulling off a successful attack wouldn't be easy."
Jeff Kagan, an independent industry analyst, said he suspects both Facebook and Twitter have turned up their security in light of the new threats but he doesn't see much else changing.
"The problem is we don't know what is serious and what is not," he said. "I think if this is the way the game is going to be played going forward, we'll just have to prepare and get used to this new reality."
Analyst Zeus Kerravala agreed: "Both Facebook and Twitter are big recruiting tools for ISIS so Zuckerberg and Dorsey are impeding the growth of the organization."
