Blockchain hit with DNS attack

Share, a popular Bitcoin wallet provider, was knocked offline for seven hours earlier this week after a domain name system (DNS) attack.

The intrusion rerouted visitors to external servers which led to the passwords of Bitcoin users being exposed, according to Hacked.

The situation was corrected quickly and function on the site was restored.

Blockchain quickly took to social media to warn its clients of the attack and even shared that funds could be put at risk and that redirects to external IPs could impact API requests and logins, allowing bad actors to siphon up login credentials on the unintended portal.

Users were advised to change passwords.

In a blog post, CEO and co-founder Peter Smith said the intrusion was the result of a “highly sophisticated attack” targeting the company's registrar and not Blockchain itself.

The company is earning praise for its transparency and frequent updates to customers.
