1. Damage from Ransomware
The recent ransomware attack that closed 800 stores of the Coop supermarket chain in Sweden is just one of a series of cyberattacks targeting US agencies, organizations, and companies that are currently operating in the US. dominate the front page of newspapers in recent times. According to Business Insider, cybersecurity experts warn that these types of attacks are on the rise and could spread throughout global supply chains.
Most recently, the ransomware attack on American technology company Kaseya affected about 800-1500 businesses around the world. Affected subjects are mainly small businesses such as dental clinics and accounting offices. The hacker group requested $70 million to recover all the data of the affected businesses.
Mr. Fred Voccola, CEO of Kaseya, said: “The level of sophistication is increasing and they can perform blackmail without too much fear of being caught by existing anonymous currencies. For example, if demanded a hundred thousand dollars in ransom to be transferred to an account at JP Morgan Chase, the FBI will find them immediately. But if you put money in an electronic wallet, the hacker is completely free.”
According to experts, what is worrisome is that recent attacks are increasingly bold and target larger-scale objects. Once the technology supply chains of the victim companies are affected, the damage will spread to many other companies, which is the most worrying consequence.
Mr. Robert M.Lee, Chief Executive Officer of Cybersecurity Firm Dragos, said: “If you are a small and medium-sized business, you also need to be prepared for attacks like this. There needs to be better awareness. and policy discussions when using cloud computing services”.
In just the first half of this year, cyberattacks large and small are spreading around the world. Right in May, there were two major attacks, one on Colonial Pipeline - an oil pipeline operator on the East Coast of the United States and caused gasoline shortages and fuel price hikes lasting a week. Second, is JBS USA - the world’s largest meat supplier, causing the company to suspend operations at 10 factories globally.
Cyberattacks using malicious code are usually carried out in an encrypted manner to isolate data in the system and demand ransom from the victim. According to cybersecurity firm Emsisoft, hackers may have earned around $18 billion of this type of ransom last year.
