The file hosting service Dropbox denied it was hacked and said the outage was just brought by maintenance.

Dropbox is one of the famously used choices for keeping files safe. It offers cloud storage, client software, and file synchronization. Also, it lets users access their files saved in it through a website or some mobile phone applications.

On Friday, Dropbox suddenly went offline for maintenance. Afterwards, a tweet from a @AnonOpsKorea surfaced claimed responsibility, "BREAKING NEWS: We have just compromised the @Dropbox Website"

Due to that tweet, several Dropbox users assumed that the service which promised to keep their files safe has been hacked.

The San Francisco, Calif.-based company immediately denied the allegations, assuring everyone that no hacking occurred.

In the company's blog post, Dropbox explained, "We are aware of an issue currently affecting the Dropbox site. We have identified the cause, which was the result of an issue that arose during routine internal maintenance, and are working to fix this as soon as possible. We apologize for any inconvenience."

After Dropbox cleared the clouds, another hacktivist group, @1775sec, mocked the company's denial and claimed it was responsible for the outage in honor of late Internet activist Aaron Schwartz. The user also tweeted that they managed to steal a number of e-mail addresses from Dropbox and trashed it on

A famous anonymous Twitter account confirmed @1775sec's allegation. However, Dropbox was quick to deny the issue again, saying in an update in its blog post, "No files were lost in the outage, but some users continue to run into problems using various parts of and our mobile apps."

Now, after all the allegations, denials, and admissions, the service has now resumed. Dropbox assured everyone that no e-mail addresses were compromised.
