A new study has revealed that black holes could be lurking much closer to Earth than anticipated. A black hole in space is when "gravity pulls so much that even light can not get out," NASA explains. "The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying." Due to no light being present, they are invisible. Only special tools can pick up on them. There are said to be around 10 million to 1 billion mass black holes in the Milky Way, according to Science Alert. However, astrologers only know of about 20 of them. Now, a recent study has revealed that they could be a lot closer to Earth than previously thought after investigating the Hyades cluster, "a group of stars located 150 light-years away". In a statement, astrophysicist Stefano Torniamenti of the University of Padua explained: "Our simulations can only simultaneously match the mass and size of the Hyades if some black holes are present at the centre of the cluster today (or until recently). The Hyades with hundreds of stars is said to be approximately 625 million years old. Due to its packed environment, "higher rates of collisions and mergers" are expected. At 153 light-years away, it is considered the closest star cluster to Earth. Researchers were able to observe two or three black holes in the Hyades, which are either still present or ejected less than 150 million years ago and hovering around the outskirts. "This observation helps us understand how the presence of black holes affects the evolution of star clusters and how star clusters in turn contribute to gravitational wave sources," Professor Mark Gieles of the University of Barcelona said.

A British hacker behind the 2020 takeover of the Twitter accounts of Elon Musk, Barack Obama, Joe Biden, and several other personalities as part of a Bitcoin scam has been sentenced to five years in prison. The hacker, 24-year-old Joseph O’Connor from Liverpool, took over nearly 130 accounts in July 2020, and pleaded guilty to charges of hacking these profiles last month. He was extradited from Spain on 26 April to face charges and now the US Attorney’s Office in the southern district of New York has sentenced him to five years for cyber crimes. In May, the hacker pled to four counts of computer hacking, wire fraud, and cyberstalking, according to Tech Crunch. The US justice department accused Mr O’Connor of participating in the exploitation of social media accounts, as well as online extortion and cyberstalking. The hacker, known as PlugwalkJoe online, has also been ordered to pay nearly $800,000 to the victims of his crimes. He had participated in the exploitation of social media accounts, as well as online extortion, using social engineering tricks to get access to Twitter accounts. New York’s Department of Financial Services investigated and found that the hackers had called Twitter employees, claiming to be the IT department. Another hacker Graham Ivan Clark – known as Kirk – reportedly used this access to hijack and reassign Twitter accounts. Using stolen accounts, hackers sent out tweets asking followers to send bitcoin to an account, promising to double their money. Mr O’Connor also pled guilty of using a cyber intrusion technique called a “SIM swap attack” to steal cryptocurrency from a Manhattan-based company and then to launder the proceeds of the scheme. In this mode of cyber attack, hackers gain control of a victim’s mobile phone number by linking that number to a SIM card controlled by the threat actors. This leads to the victim’s calls and messages being routed to a malicious unauthorised device controlled by the hackers, who then use control of the victim’s mobile phone number to obtain unauthorised access to accounts held by the victim registered to their mobile phone numbers. Twitter said it improved the social media platform’s cybersecurity controls following the cyberattack. In addition to the prison term, Mr O’Connor has been sentenced to three years of supervised release and further ordered to pay about $794,000 in forfeiture.
