Celebrity twitter accounts are a common target for hackers. K-Pop boy band BTS recently had their account compromised by elite hacker group known as OurMine.
Hi, we are OurMine. Everything is hackable to improve your accounts security. Contact us: firstname.lastname@example.org. For security services visit ourmine.org. Let's get #BTSHack trending.
The idea is to advertise their commercial services, through the hashtag. OurMine describe themselves as white hat hackers, with 'no bad intentions'.
They claim to only care about the security and privacy of your accounts and network. But the group have become renowned for their highly controversial activity, hacking CEO's and celebrities.
They pride themselves on being versatile: 'We are experienced in many fields of hacking and can crack anything from a network to a social media account'.
One of their services, for instance, costs $30 (£23) and includes a personal scan of social media accounts, email and iCloud.
The tweet was swiftly deleted and fans - referred to as ARMY - were quick to respond by turning the table. Twitter users in support of BTS defended the boy band by mocking OurMine for failing to target the main BTS account.
The hashtag was primarily used to criticise the hacker group and share humour about the situation through memes.
Other users took advantage of the hashtag to promote new music by the boy band. Some twitter accounts also warned others not to share the hashtag, as it would give OurMine their desired publicity.
