A wave of cyber attacks have hit the coding site GitHub, the work chat service Slack and British Airways' air-miles accounts.

Many user accounts were compromised and the firms are tackling them in their own ways.

Some Uber, car pick-up service,  users have also reported the hacks but the company said it had "found no evidence of a breach".
