Hackers

Staff at SP Workwear say they were locked out of their account overnight and have lost their valuable social media profile and customer base.

The group is believed to have been behind a number of high profile cyber attacks in recent years, including one on Royal Mail last year.

Poly Network was the victim of one of the biggest cryptocurrency hacks in history last week when the hacker, "Mr White Hat," drained $611 million (£444m).
