If a group of Marvel superheroes can't fend off a hacking attack, what chance do the rest of us have? It turns out that hacker team/security company OurMine is up to its old tricks again. After compromising US Netflix's official Twitter account yesterday, the group took control of Marvel's main profile and several of its affiliated accounts.

As it has done in the past, OurMine issued messages on the accounts that stated it was "just testing" security. The group also included contact information and links to its website, where it offers to help people stay safe online. Services include social media account protection for $30, and website or corporate network protection for $1,000 to $5,000.

US Netflix's 2.4 million followers noticed the account had been compromised early Wednesday morning. After the streaming site regained control and deleted the messages, OurMine took over Marvel's Twitter account and those of its superhero franchises, which are used for promotional purposes.

Black Panther, Captain America, Iron Man, Ant-Man, Thor, Doctor Strange were all hacked, as was Marvel Music. The company managed to gain access the accounts about 10 minutes after the messages first appeared.

A member of OurMine told Mashable he hacked Netflix's Director of Social Media and then used that account to access more Netflix accounts.  

Some high-profile names that have fallen victim to OurMine this year include Mark Zuckerberg, Sundar Pichai, Channing Tatum, Uber's Travis Kalanick, TechCrunch, Jack Dorsey,  Wikipedia co-founder Jimmy Wales, BuzzFeed and Forbes

October's BuzzFeed hack was retaliation for reporter Joseph Bernstein's article that identified Saudi teenager Ahmed Makki as a member of OurMine, something the group denies.
