Facebook CEO Mark Zuckerberg grilled by US Senate and Congress in two-day hearing

US lawmakers grilled CEO of Facebook Mark Zuckerberg last week over the social networking giant’s repeated data privacy problems and subsequent apologies. Zuckerberg endured five hours of enquiry by members of the House Energy and Commerce Committee in what was the second of two hearings set following the news that political consulting firm Cambridge Analytica may have gained access to the personal data of up to 87 million Facebook users.

The repeated questioning over the nuances of Facebook’s data gathering techniques seemed to catch Zuckerberg off guard, and his lack of detailed answers appeared to frustrate some lawmakers who are concerned that another Cambridge Analytica scandal could happen under his watch.

YouTube's most popular video – Despacito – suffers a hack attack

Nothing is safe on the internet, not even Despacito – the most popular video on YouTube, as hackers recently defaced a number of music videos that were posted to YouTube by Vevo accounts. Among the affected videos was the world-famous music video by Luis Fonsi and Daddy Yankee, which was also taken down.

The hackers, who called themselves Prosox and Kuroi'SH, replaced some of the videos' thumbnails with photographs of a masked gang holding guns from Netflix's Casa de Papel. This breach is not the first instance of trolling from these users. Someone also identifying themselves as Kuroi'SH hacked a number of news organisations' Twitter accounts, including that of NowThis and tweeted a range of posts including his name.
