An Irish regulator helping police European Union data privacy on Tuesday announced that it fined Facebook’s parent company, Meta 251 million euros ($263 million) for a data protection failure that led to accounts being hacked.
The Data Protection Commission (DPC) faulted Meta for a security flaw in its video upload function which hackers were able to exploit to gain full access to other users’ Facebook profiles.
In 2018, unauthorised users were able to hack into around 29 million Facebook accounts globally, illegally exploiting personal data including email addresses, phone numbers, locations and places of work.
“The failure to build in data protection requirements throughout the design and development cycle can expose individuals to very serious risks and harms, including a risk to the fundamental rights and freedoms of individuals,” said Graham Doyle, the regulator’s head of communications.
“By allowing unauthorised exposure of profile information, the vulnerabilities behind this breach caused a grave risk of misuse of these types of data,” he added.
Meta Ireland and its US parent company remedied the breach shortly after its discovery, the DPC said and reported the issue to the regulator in September 2018.
It is the latest fine in a series issued to the US social media giant and its rivals, as global regulators crack down on tech companies.
In September, the DPC fined Meta 91 million euros for failing to put in measures to protect users’ password data and for taking too long to alert the regulator of the issue.
