Hackers impersonating high-profile personalities is considered the “most significant attack in the history of Twitter,”—shows the risks of using Twitter are very high.

Accounts such as those of Kanye West, Joe Biden, Barack Obama, Bill Gates, Mike Bloomberg, Apple Inc., and companies related to bitcoin transactions, among 40 others, were supplanted on July 15 trying to scam money, and in fact, hackers made at least $120,000, according to the Washington Examiner on July 27.

The FBI is investigating the breach that allowed the hackers to tweet repeatedly from the verified accounts, and if those tweets had been manipulated by an enemy government the consequences could be devastating.

Reuters discovered earlier this year that 1,000 Twitter employees and contractors, had access to the system and could control account users access and information just like the hackers did.

Twitter CEO Jack Dorsey admitted to shortcomings in the company he heads.

“We fell behind, both in our protections against social engineering of our employees and restrictions on our internal tools,” Dorsey told investors, according to Reuters.

In turn, Ron Gula, a cybersecurity investor and co-founder of network security company Tenable, questioned the security measures implemented by the network, “The question really is: Does Twitter do enough to prevent account takeovers for our presidential candidates and news outlets when faced with sophisticated threats that leverage whole-of-nation approaches?”

The controversial censorship and limitations on free expression imposed by Twitter

The directives Twitter has imposed on this high-profile social network is the cause of multiple controversies, including its tendency to censor and hinder free expression by its users.

The U.S. president and many of his followers have issued complaints about it.

It is “disgusting to watch Twitter’s so-called ‘Trending,” where sooo many trends are about me, and never a good one.  They look for anything they can find, make it as bad as possible, and blow it up, trying to make it trend. Really ridiculous, illegal, and, of course, very unfair,” Trump said according to Fox News on July 28.

Republicans and other conservative users agree that Twitter favors Democrats and leftist policies.

“President Trump is committed to protecting the rights of all Americans to express their views and not face unjustified restrictions or selective censorship from a handful of powerful companies,” U.S. Commerce Secretary Wilbur Ross said, according to Fox News.
