It looks like the OurMine crew is back and they're on a hacking spree, taking brief control of the social media accounts of high-profile individuals.

OurMine took a break from media attention in 2017 but on January 22 they started to claim the spotlight again by hacking Twitter accounts of users flush with followers.

NFL teams lined up for today

In the latest round that happened today, they targeted the Twitter, Facebook, and/or Instagram accounts of multiple teams in the National Football League (NFL) and that of the League itself.

The tally for the day counts the seven victims below, which combined have tens of millions of followers:

Dallas Cowboys (Instagram and Facebook)

Buffalo Bills (Instagram and Facebook)

Houston Texans (Facebook)

Minnesota Vikings (Instagram and Facebook)

Kansas City Chiefs (Twitter)

Green Bay Packers (Twitter and Facebook)

NFL (Twitter and Facebook)

The day before, the hackers accessed the Twitter account of Chicago Bears publishing a message for all 1.8 million followers to see: the team has a new owner and he paid $1 (yes, one USD) to get it.

OurMine calmed everybody in a subsequent tweet that revealed the prank.

The list of NFL teams that got hit by OurMine is larger, though, as various sources, including users on Reddit, report that social media accounts for half of them fell victim to hijacking:

Arizona Cardinals (Twitter)

Cleveland Browns (Twitter)

Denver Broncos (Twitter)

Indianapolis Colts (Twitter)

New York Giants (Twitter)

Philadelphia Eagles (Twitter)

San Francisco 49ers (Twitter)

Tampa Bay Buccaneers (Twitter)

Control of the accounts was lost only for a brief time but the hackers' quick actions made quite an impact. In just two hours, OurMine announced on their Twitter timeline that they had hijacked social media accounts of so many NFL teams.

Although this seems to be the peak of their activity in a long time, the hackers started the hijacking on Tuesday, the first victim of their victims this year being Eduardo Saverin, Facebook co-founder, now an angel investor.

Next in line were the following Twitter accounts:

OurMine's Twitter account is now suspended and their hacking marathon appears to be for the 'lulz' and to promote the group by showing high-profile individuals that they need to improve security for their social media accounts.

This is not difficult and the options are all there. Setting unique passwords for each account and turning on two-factor authentication (2FA) should be enough to prevent hackers from taking control of their online assets.
