Jake Williams, chief technical officer of the cybersecurity firm BreachQuest, said that while foul play cannot be completely ruled out, chances were good that the outage is “an operational issue” caused by human error. “They’re more susceptible to social engineering because they’re so desperate to communicate.” Tobac said during previous outages, some people have received emails promising to restore their social media account by clicking on a malicious link that can expose their personal data. “They don’t know how to contact the people in their lives without it,” she said. So many people are reliant on Facebook, WhatsApp or Instagram as a primary mode of communication that losing access for so long can make them vulnerable to criminals taking advantage of the outage, said Rachel Tobac, a hacker and CEO of SocialProof Security.
Without Facebook broadcasting its routes on the public internet, apps and web addresses simple could not locate it. Such routes are part of the internet’s Domain Name System, a central component of the internet that directs its traffic. Madory said it appears Facebook withdrew “authoritative DNS routes” that let the rest of the internet communicate with its properties. Facebook’s request Monday that a revised antitrust complaint against it by the Federal Trade Commission be dismissed because it faces vigorous competition from other services seemed to ring a bit hollow. It also showed that, despite the presence of Twitter, Telegram, Signal, TikTok, Snapchat and a bevy of other platforms, nothing can truly replace the social network that has evolved in 17 years into all but critical infrastructure.
