1. ransomware virus 2019 in Hydro
In March 2019, Hydro’s IT systems were affected. It was a scope they hadn’t seen before. The attack caused Hydro to rip out cables from 22,000 computers on five continents.
The ransomware virus locked files and shut down computer users. The virus, called LockerGoga, required Hydro to pay a ransom to unlock it.
Tasks that often happen digitally had to be solved with pencil and paper. Several of the computer systems were completely broken.
Hydro took several months to build a new computer system.
NOTE: A cyber attack meant that Hydro had to spend several months rebuilding its computer system.

2. 2018: Southeast Health
In January 2018, intruders gained access to the Health South-East network. The hackers were able to view information about patients, research, and contingency plans.
It was unclear if any information about the patients was stolen. According to the Health Trust, it was unlikely. The police security service (PST), for its part, said this could not be ruled out.
According to PST, the professionals were behind the attack. They never knew who.
3. 2017: WannaCry
The ransomware virus known as WannaCry shut down hundreds of thousands of computers. More than 150 countries were affected.
The attack on data in May had a widespread impact. The virus went after computers that did not have all the security updates from Microsoft.
Both individuals and businesses were affected. Norway escaped with a few scratches. According to security authorities, this is because Norway has high IT security in general.
4. 2017: Petya
A month after WannaCry, Norway and other countries were targets again.
Authorities, large companies and banks from several European countries were attacked. The ransomware virus became known as Petya.
Ukraine was one of the worst affected countries. The authorities, the banks, the press and the electricity companies had problems.
Employees at the Chernobyl nuclear power plant had to measure the radiation by hand. The usual tracking system was down.
Although there was no danger of radioactive discharges, this was a powerful reminder. A country is vulnerable when critical infrastructure is attacked.
Ukraine blamed Russia. It was never proven by Russia who was behind it.
The virus spreads in the same way as the WannaCry virus. Exploited security holes in the computer. When the virus first entered, it spread to all other computers on the same network.

5. 2016: Attack on Democrats in America
In 2016, the United States accused Russia of trying to influence the presidential elections. The background was a computer attack on the Democratic Party.
The data breach by the party’s national committee led to important emails being leaked to various websites.
Russian authorities denied they had anything to do with the robbery.
The data breach had a direct impact on the national gathering of the Democrats. Then internal emails were posted. They showed that party leaders supported Hillary Clinton over Bernie Sanders. It was at a time when the party apparatus should not have taken a position.
The revelations led the committee’s leader, Debbie Wasserman Schultz, to resign just before the national meeting.

On Christmas Eve 2015, many hundreds of thousands of Ukrainians were without electricity. The reason was a computer attack. The blackout must have lasted several hours. Several power plants were shut down.
The attack is considered one of the first successful cyber attacks against power companies.
Ukraine later fell victim to several targeted cyber attacks. Not least in the run-up to the 2019 presidential election.
7. 2014: Attack on Norwegian power
In August 2014, at least 50 Norwegian companies received an email with a dangerous attachment. All companies belonged to the oil and energy industry.
Those who opened the attachment got a malicious virus on their computer systems. Could be expensive and dangerous The attack was discovered before it did much damage.
National security authorities weren’t just afraid of espionage. They also feared that the attack could stop or destroy actual production in the energy industry.
This time it was also not possible to determine who was behind it. National security authorities denied that there were “boy jokes.” It was a complex and tailor-made attack.
8. Robbery at the United States Department of Defense
In March 2011, foreign data thieves allegedly obtained 24,000 files from the US Department of Defense, dealing with sensitive military information.
The Pentagon at the time described the data breach as the worst they had ever been subjected to.
The US Department of Defense was also the target of a major cyber attack from abroad in 2008. The Department of Defense spent more than a year cleaning the computer network of the worm called “agent.btz”.
Since then, the Pentagon has been the target of a series of cyber attacks.

9. 2010: Stuxnet threatens Iran’s nuclear facilities
The Stuxnet computer worm was discovered in the summer of 2010. The program, which was first called the “Olympic Games,” was sneaked into Iran in September.
Stuxnet is supposed to have done great damage to Iran’s nuclear weapons program. The country has never confirmed it.
This worm also entered through a security hole in the software. It was aimed at the management systems of large companies or authorities.
The worm attacked Iran, Indonesia, India and the United States.
No one has openly acknowledged having made Stuxnet. According to Wikipedia, many people wonder if the worm was created by the United States and Israel together as a cyber weapon.

Explain
Why is email so interesting to hackers?
for answers
Email is in many ways the key to our digital life. There you will often find conversations dating back several years in time and confidential documents.
By accessing an email account, you can also access other online services. You can indicate on a website that you have forgotten your password. Then there will be a link to the email account and you will have access to the website.
How do hackers access someone’s email?
It is quite common for people to use the same password in multiple places. Simple passwords a hacker can guess. Many also have passwords that deviate from previous data breaches, something hackers diligently use in new attacks.
Are emails from ordinary people vulnerable?
In recent years, it has become increasingly popular to target companies and organizations with so-called ransomware viruses. These viruses shut down all the computers they access. Many of these attacks start with a seemingly innocent email sent to one or more company employees.
It is also common for criminals to attack the private email accounts of people with an important role in a company. These hackers often have financial motives for the attack.
When private accounts are attacked, it is because the owner is in some way interesting to the attacker.
How can I protect myself from being hacked?
The most important thing you can do is get a double factor on the email account you have at work and in private. With two factors, you get a unique and temporary code via text message or in an app. This makes it much more difficult for an attacker: now they need to know both your password and the unique code to enter.
Experts also recommend that you get a so-called password manager. It is a program that stores all your passwords in one place. In this way, you can have different passwords on all web pages, while I need to remember a password.
