Hacking is a relatively new field of science, but its origins are well-known.
It dates back to the 1970s, when the US Army first used it as an anti-communist weapon, and was also used by the military of other countries during the Cold War.
Hackers are generally considered to be experts in the field of computer hacking, and are known to be the best at breaking into computers and operating them.
In recent years, a number of companies have been caught up in the industry, including Symantec, which has been hit with hundreds of lawsuits over breaches of personal data.
In the case of the Hackearth, which broke into a computer network at a hospital in Germany in 2009, the company admitted to its own mistakes and paid a $100m fine.
The Hackelhar group, which was later found to be using a number similar to the Haxherber group, was also found to have breached the same hospital’s systems.
But the US Government has come under fire for failing to crack down on the Hacskear group.
“Hackears, while they may be good at their job, are also the biggest perpetrators in this whole cybercrime business,” said Mark Sperling, a former deputy US attorney general, in a speech at the US Chamber of Commerce last year.
“This is a big problem, because if the United States and other countries can’t be trusted to keep their cybersecurity up, how are we going to be able to keep ourselves safe from other people doing the same thing?”
Hackers typically target corporate networks, where they can access data from thousands of computers, usually with little effort.
Hack attacks typically take place against websites or other sites which are run by large corporations, but in the case with hospitals, the hacks have been carried out by hackers from the internet and the hacker forums.
As the attacks have been more sophisticated, so have the targets, and in one case, the hospitals themselves.
The breach in the HACKEAR group was found to include at least five large hospitals, including those in New Jersey, New York, Connecticut, Massachusetts, and California.
In many of the attacks, the attackers used tools known as botnets, which are networks of computers that are controlled by a single entity, usually a company or a government organisation.
A Hackeearth spokesperson told New Scientist: “We have seen evidence that the Hacks have targeted hospitals.
These attacks were not malicious, but it is clear that these hackers are highly skilled.”
In a statement, the Department of Health and Human Services said it was “deeply concerned” by the breaches.
“As we have said many times, our cyber security posture is robust and secure.
DHS has been actively working with state and local partners to strengthen our defenses, and will continue to take every possible step to protect the healthcare system,” the statement said.
The department also said that it was working with hospitals to strengthen security procedures.
“The Department of Homeland Security has been working closely with the states and localities in securing the health care system, and working with the Department to develop policies and protocols that will help protect the health and well-being of our health care workers,” the spokesperson said.
“We will continue working with DHS and the federal government to ensure that the health systems we provide the best cybersecurity.”
The Hacskeearth was also part of the “WannaCry” ransomware attack which affected more than 50,000 computers worldwide in May.
The group has since claimed responsibility for a string of other attacks, including the “Cryptorber” ransomware which spread via the dark web.
The UK’s Computer Emergency Response Team said it had already been working with cyber security firms to protect against “future attacks”.
The NHS said it would work with the government and private sector firms to strengthen their cybersecurity defences.
“There is always more to do,” said a spokesperson.
“Our cybersecurity teams work tirelessly to protect and protect our hospitals and other NHS organisations, but this is only part of our long-term plan to keep our healthcare facilities safe.”
