Trend Micro cybersecurity experts warned of a record increase in threats, with critical sectors; government, banking and health; as the main targets of criminals. Specifically, they specify that it is an increase of 42 % year-on-year in 2021, to exceed 94,000 million cyber attacks detected.

This is revealed by its latest study, which warns of the spiral of risks for digital infrastructure and remote workers. “Attackers are always working to increase their kill numbers and profits, whether through the number or effectiveness of attacks”, said Jon Clay, Vice President of Threat Intelligence at Trend Micro.

Ransomware attackers are shifting their focus to critical businesses and industries that are more likely to pay, and double-extortion tactics guarantee them profit. Additionally, experts found that cybercriminals are offering ransomware-as-a-service campaigns, opening the market to attackers with limited technical knowledge.

Threat actors are also getting better at exploiting human error to compromise cloud infrastructure and remote workers Trend Micro Cloud App Security (CAS) detected and prevented 25.7 million email threats in 2021, compared to 16.7 million in 2020, while the volume of blocked phishing attempts nearly doubled over the period.

Research shows that home-based employees tend to be more likely to be at risk than office-based employees, making phishing a particular risk. Attacks with messages linked to Covid-19 continue to be a threat, although their intensity has decreased compared to 2020.

In the cloud, misconfigured systems are “a plague” for organizations, experts add. When services have relatively high misconfiguration rates, they are exposed to attacks by cybercriminal groups like TeamTNT, which deploy cryptocurrency mining malware on affected systems.
