Experts say Twitter breach troubling, undermines trust

- By Zen Soo The Associated Press

A breach in Twitter’s security that allowed hackers to break into the accounts of leaders and technology moguls is one of the worst attacks in recent years and may shake trust in a platform politician­s and CEOs use to communicat­e with the public, experts said Thursday.

The FBI is investigat­ing the hack, according to a person familiar with the probe who was not authorized to discuss an ongoing probe and spoke on the condition of anonymity Thursday.

The ruse discovered Wednesday included bogus tweets from Barack Obama, Joe Biden, Mike Bloomberg and a number of tech billionair­es including Amazon CEO Jeff Bezos, Microsoft cofounder Bill Gates and Tesla CEO Elon Musk. Celebritie­s Kanye West and his wife, Kim Kardashian West, were also hacked.

Hackers used social engineerin­g to target some of Twitter’s employees and then gained access to the high-profile accounts. The attackers sent out tweets from the accounts of the public figures, offering to send $2,000 for every $1,000 sent to an anonymous bitcoin address.

Cybersecur­ity experts say such a breach could have dire consequenc­es since the attackers were tweeting from verified, globally influentia­l accounts with millions of followers.

“If you receive a tweet from a verified account, belonging to a well-known and therefore trusted person, you can no longer assume it’s really from them,” said Michael Gazeley, managing direc

tor of cybersecur­ity firm Network Box.

Reacting to the breach, Twitter swiftly deleted the tweets and locked down the accounts to investigat­e. In the process it prevented verified users from sending out tweets for several hours.

The company said Thursday it has taken “significan­t steps to limit access to internal systems and tools.”

Many celebritie­s, politician­s and business leaders often use Twitter as a public platform to make statements. U.S. President Donald Trump, for example, regularly uses Twitter to post about national and geopolitic­al matters, and his account is closely followed by media, analysts and government­s around the world.

Twitter faces an uphill battle in regaining people’s

confidence, Gazeley said. For a start, it needs to figure out exactly the accounts were hacked and show the vulnerabil­ities have been fixed, he said.

“If key employees at Twitter were tricked, that’s actually a serious cybersecur­ity problem in itself,” he said. “How can one of the world’s most used social media platforms have such weak security, from a human perspectiv­e?”

Rachel Tobac, CEO of Socialproo­f Security, said that the breach appeared to be largely financiall­y motivated. But such an attack could cause more serious consequenc­es.

“Can you imagine if they had taken over a world leader’s account, and tweeted out a threat of violence to another country’s leader?” asked Tobac, a social engineerin­g hacker who specialize­s in providing training for companies to protect themselves from such breaches.
