Despite the over 100 indictments (Apt41, Malaysian, Russian, Chinese, and North Korean hackers) in the U.S. this year, many of these cyber criminals were not arrested. Most of them were able to return to their country of origin. And sometimes, they were hacking from other countries.
Ransomware attacks are becoming more sophisticated
Various international hacker groups have developed strains of malware that can infect a network of computers. When they exploit the system of a hospital, a big company, or a governmental agency they demand ransom to give the victim back their own system.
And in 2020 ransomware evolved. This evolution included the double extortion attack. In the late November attack on Advantech, the cybercriminals stole the data then encrypted the data in the system. They can get paid twice. First for not leaking the data. Then they want ransom for giving the company an encryption key to free up their network.
In 2021, ransomware will almost certainly remain a critical part of the malicious hacker’s toolkit. And expect cybercriminals to go deep into the healthcare infrastructure, where attackers can steal patients’ records for blackmail.
