In the past eight months, most of the things have changed beyond recognition – the way we live and work. Due to the pandemic, the use of the internet and the cybersecurity incidents have increased tremendously. Since the beginning of 2020, there have been more than 445 million cyberattacks reported, which is double when compared to 2019.

While the IT environment is becoming more complex, cybercriminals are getting better at identifying and targeting the intrinsic weaknesses. Nearly 40% of IT security, line-of-business, and data management specialists cited the rising sophistication of attacks and the increasing complexity of managing and supporting security products as significant challenges, according to IDC’s Data Services for Hybrid Cloud Survey.

Attackers benefit from complexity, which may lead to configuration weaknesses and user ignorance. The thing is most of the companies are already aware of the weaknesses in their system. If they take proper steps, then they can avoid cybersecurity incidents better.

Below are a few cybersecurity incidents that took place in 2020. The rankings are based on the impact the security breach caused to the company.

The hacker, named ShinyHunters is believed to have made a lot of money by selling the data online.

After hackers steal the data, they usually sell it privately first, with prices ranging from $500 to $100,000. Once the data is no longer useful, hackers generally publish them on hacker forums to increase their reputation in the community.

This cybersecurity incident started in the mid of 2019. Then, the MGM employees discovered unauthorized access to a server. From that day, the stolen information was being shared in several hacking forums.

After the cybersecurity incident got revealed, immediately MGM notified the impacted individuals. In February, once again there was a data breach and as a result, information of MGM hotel users was published openly, on an accessible forum.

Impact: Disruption of client services, revenue and impact on margins. The company paid $50-70 M for ransom.

On April 18, 2020, Cognizant Technology Solutions (CTS), was hit by Maze ransomware cyber-attack, which resulted in service disruption of company’s clients. 

The tech giant confirmed the breach on its website. It took steps to contain the cybersecurity incident and notified its clients about the breach and measures to take to further secure their systems. 

During a ransomware data breach attack, attackers generally infect the company’s systems with the virus, steal the data, and demand payment from the company to restore the data. But, in case of Cognizant Maze ransomware, attackers threatened the company to pay the ransom or they would publish the breached information online.

Later, in May, Cognizant revealed that it paid a ransom of $50-70 million to cyber attackers to restore its services.

Impact: A ransom of $1.14M paid.

On June 1, University of California, San Francisco, was attacked by cyber criminals. This was again a ransomware attack and hackers demanded $3 million. The leading medical-research company negotiated the ransom amount and paid $1.14 million as the information encrypted in the attack was critical to the school.

Cyber criminals penetrated the university’s system through a malware that eventually encrypted multiple servers. The university officials later said that no data was compromised, and their development progress was not completely hampered.

Take Action Now:  Backup  your data- locally, or in the cloud.

6. Tillamook County

Impact: 250 county employees and 25,000 citizens records affected; $300,000 paid for ransom.

This year, on January 22, the Tillamook County’s IT government systems were infected by a malware attack. Hackers penetrated the county’s computer and phone systems through encryption malware. Consequently, the county’s systems were shut down. Their website that hosts numerous departments, was also turned off.

Following the cybersecurity incident, the computer systems were disabled for almost two weeks or possibly longer. The attackers told the county officials that their files were encrypted and won’t be recovered without their decryption service. The attackers demanded $300,000 ransom to let the county regain the data and threatened to double the ransom if not paid on time.

The county officials made every effort to avoid the ransom payment, including recovery through data backup; however, their critical data could not be restored. In the end, the county officials paid the ransom to the cyber attackers.

Take Action Now: Ensure business continuity of your critical systems and protect against harmful websites.

#7 World Health Organization (WHO)

Impact: 25,000 email addresses and passwords stolen.

Among the cybersecurity incidents so far in 2020, stealing data from important organizations who are fighting the COVID-19 pandemic is particularly shocking.

On April 19, some 25,000 email addresses and passwords were leaked online belonging to several groups working to fight the coronavirus pandemic, including the WHO, NIH, the US Centers for Disease Control and Prevention (CDC), and the Gates Foundation.

Later, the WHO publicly confirmed that some credentials belonging to its staff were leaked. However, the data stolen was not recent, and therefore, the data breach did not pose any risk to the organization. It also did not disclose how the attackers might have obtained the information. The WHO, in a statement, later noted that they were migrating the affected systems to a more secure and authenticated one.

Take Action Now: Step up your security. Choose a modern cybersecurity solution over traditional ones.

#8 Energias de Portugal (EDP)

Impact: 10 TB data stolen, and $10.9 M demanded.

The Portugese multinational energy company, Energias de Portugal (EDP) faced one of the most threatening cybersecurity incident in April 2020.

A ransomware attack, named RagnarLocker successfully targeted EDP. The cyber-attackers demanded a ransom of $10.9 million to unlock its files. The files contained critical data, including contracts, billing details, transactions, client’s and partner’s personal details like names, passwords, etc.

In a ransom note on the site, the hackers claimed that they will publish the information on public blogs or websites if the ransom goes unpaid.

RagnarLocker ransomware has the potential to infect a system and prevent virus detection, and severely damage the infrastructure of a company. The energy firm, however, has not disclosed if they paid the ransom, or steps that it took to investigate the attack.

Take Action Now: Keep backups of all the critical data.

#9 Zoom App

Impact: Reputation and brand image damaged.

In April 2020, Zoom, a famous video conferencing app, was amid a controversy.

During coronavirus, as stay-at-home orders were put into practice across the globe to limit the spread of the disease, the use of video conferencing apps increased, and Zoom was among the most used ones.

In April, there was an attack, Zoombombing, where people with bad intentions could join the private meetings, read conversations, and screen share images of whatever they wanted, mainly sort of offensive, like adult or shock videos.

There were a lot of other security concerns in the Zoom app. The company later updated its iOS app to stop sending user data to Facebook. Zoom later improved the security of their Zoom meetings as well.

Take Action Now: Know your security settings. Use tools to block unauthorized access.

The breached data mainly contained information such as applicant information (1987 people), employee data (4566 people), and retired employees’ data of affiliate companies (1569). There was also data related to technical and sales materials.

The cause behind the cybersecurity incident was a bug in their antivirus. The Chinese hackers were believed to use a zero-day in the Trend Micro Office Scan antivirus, which allowed them to access the initial entry point.

Take Action Now: Use a highly advanced cyberprotection solution.
