Remote desktop protocol (RDP) attacks boost by 768% involving Q1 and Q4 very last calendar year, fuelled by the shift to distant doing work, according to ESET’s Q4 2020 Menace Report.
Nonetheless, a slower amount of expansion was noticed in the final quarter of the yr, indicating that companies have enhanced their security for remote buyers.
A different essential finding from the report was a increase in COVID-19-themed email threats in Q4, with the vaccine rollout specifically greatly targeted. When compared with Q3, vaccine mentions in malicious e-mails ended up up by 50%, highlighting the sturdy lures this subject offers. These include business proposals in vaccine enhancement, delivers on extremely-reduced-temperature freezers and vaccine-related conspiracy theories. ESET expects cyber-criminals to continue on leveraging this issue via email assaults during the coming 12 months.
ESET also highlighted the world-wide disruption campaign it took aspect in against one particular of the greatest and longest-lived botnets, TrickBot. This led to 94% of TrickBot’s servers becoming taken down in a single week. Jean-Ian Boutin, head of danger research at ESET, commented: “There was a sharp decrease in TrickBot’s things to do pursuing the disruption procedure late previous calendar year. We are constantly checking the TrickBot botnet, and the degree of activity remains very small to this working day.”
In addition, the cybersecurity firm uncovered investigate conclusions about a range of provide chain assaults in the course of Q4, which are primarily suitable provided the SolarWinds attack that took place in December 2020. These contain a previously unknown APT team known as XDSpy, a Lazarus attack in South Korea and a Mongolian supply chain attack named Procedure StealthyTrident.
Boutin extra: “RDP security is not to be underestimated specifically owing to ransomware, which is commonly deployed by RDP exploits, and, with its ever more aggressive ways, poses a excellent risk to equally non-public and public sectors. As the security of distant function little by little enhances, the increase in attacks exploiting RDP is expected to gradual down – we previously noticed some signals of this in Q4.”
