NTT Ltd revealed that the healthcare, manufacturing, and finance industries were the targets of cyber attacks, which increased significantly compared to 2019.

NTT Ltd. has announced the 2021 Global Threat Intelligence Report (GTIR), which uncovers how hackers can take advantage of the world’s instability by targeting the most critical and vulnerable industries from having to work remotely. The healthcare, manufacturing and finance industries saw the highest increase in attacks (200%, 300% and 53%), with these top three sectors adding a combined total of 62% of all attacks in 2020, which is an 11% increase from 2019 .

As organizations race to promote a more virtualized approach, remote access via the use of client portals, attacks on specialized applications and web-based applications soared, accounting for 67% of all attacks, and more than doubled in the past two years. Healthcare services account for 97% of attacks of this type resulting from switching to telehealth and remote care.

The cyber threat intelligence report provides a wealth of insight from NTT Cybersecurity Advisors who have applied the maturity value of each industry’s security program to higher marks for its more mature countermeasures plans. It should be noted that the healthcare and manufacturing industries have relatively low maturity values, at only 1.02 and 1.21, respectively. This value has decreased from 2019 by 1.12 and 1.32 respectively, while on the other hand the attack rate has increased significantly.

The manufacturing industry has experienced a decline in value over the past three years, most likely due to changes in the operational environment and the evolution of attacks. In addition, the financial industry continued to show its highest benchmark value for the third year in a row, which was at 1.84, down 0.02 from a year ago.

“Last year we expected an increase in opportunistically targeted attacks, and unfortunately it is evident that these attacks are happening. While these industries have done their best to maintain critical services during difficult times, they have failed to meet the security standards that have been set at a time when companies The need for it is really very worrying. While the services provided continue to be done online and the services provided are becoming increasingly digital for the new normal, organizations must be more vigilant in maintaining and maintaining their best security,” said CEO of NTT Security Division, Kazu Yozawa.

At the moment malware has become a commodity because of its features and functions, malware has also become more diversified over the past year with growth malware which is multi-functional. On the one hand cryptominers have replaced spyware as malware the most common in the world, but the use of malware with certain types aimed at specific industries continues to develop. Worms most often appear in the financial and manufacturing sectors. The healthcare industry is affected by trojan due to remote access, while the technology industry is being targeted ransomware. The education sector was attacked by the cryptominers due to the popularity of crypto mining among students by taking advantage of their completely unprotected infrastructure.

The cryptocurrency market is a prime example, where these crypto miners have donated 41% of all malware detected in 2020. XMRig coinminer was the most common variant representing almost 82% of all activities coinminer even 99% in EMEA.

Mark Thomas, who heads the NTT Global Threat Intelligence Center said, “On the one hand criminals are taking advantage of a global catastrophe, and on the other hand cybercriminals are taking advantage of an unprecedented market boom. Both situations present uncertainty and risk. Changes in operational models or the adoption of new technologies have provided opportunities for criminals, which is also driven by a surge in the market for cryptocurrencies that are popular with inexperienced students so attacks are inevitable. Now that we are entering a more stable phase of the pandemic, organizations and individuals must be able to prioritize cybersecurity across all industries, including the supply chain.”
