Facebook accounts in Twitter and Instagram were hacked

Since the use of social media became massive, cybercriminal groups have devoted considerable efforts to finding ways to breach the security of these platforms. Over the past weekend, official Facebook accounts on Twitter and Instagram were compromised by a group of hackers. Reports indicate that the cybersecurity incident is the responsibility of the self-named hacking group “OurMine”.

By taking control of the attacked accounts, OurMine hackers began posting images with their logo, adding a message: “While their security is better than Twitter’s, even Facebook is hackeable.” Soon after, social media companies announced that account control had already been restored to the companies.

Subsequent reports mention that the hackers’
intention was to demonstrate the presence of some security vulnerabilities on
attacked social networks. A couple of weeks ago, professionals and
cybersecurity enthusiasts reported the hacking of the Twitter accounts of
multiple Teams of the US National Football League (NFL), an incident that was
also attributed to OurMine hackers.

Regarding the incident, Facebook mentioned that the attack was limited to the accounts of social media platforms, while Twitter announced that the identified accounts were deactivated as soon as the cybersecurity incident was detected, which required joint work of the security teams of both companies.

Although unauthorized posts have already been
deleted, dozens of social media users noticed anomalous activity and had time
to take some screenshots that show the presence of hackers on compromised
platforms. In some of these posts, OurMine
identified themselves as a group of white hat hackers (ethical hackers) without
malicious intentions. However, the cybersecurity community doubts on OurMine good
intentions, as its methods are clearly a form of illicit activity that includes
hacking methods such as brute force attacks, theft of login credentials, among
others.

In previous years, the International Institute
of Cyber Security (IICS) attributed some similar incidents to OurMine, such as
the attack on Jimmy Wales, co-founder of Wikipedia, against Twitter CEO Jack
Dorsey and the hacking attempt against Sundar Pichai, CEO of Google.
