What made you think that twitter didn't upgrade their security systems? What made you think that hackers didn't upgrade their hacking knowledge? Why do you think that sueing Twitter will put an end to hacking?
Well, the content presented by this thread made me think giants like twitter aren't putting enough effort to keep their users safe, besides other informations I see around since years ago regard facebook leaking data and so on.
If affected users felt morale damaged they can sue the company of course. It won't put an end to hacking, but it will put some pressure on the company to priorize the platform's security, what I think very reasonable considering the recurrent leaks and the hypothesis they aren't storing users data safely:
The sad reality is, many tech and financial giants store passwords in plaintext which leaves accounts vulnerable.
I understand employees are working from home, that can make the job harder and safety measures more complicated and delicated, but it can't be an excuse. They are supposed to offer better services for being on the spot they are among all social medias platforms. They are also supposed to handle problems faster:
“Twitter's response to this hack was astonishing. It's the middle of the day in San Francisco, and it takes them five hours to get a handle on the incident,” said Dan Guido, CEO of security company Trail of Bits.
