The number of crypto mining attacks increased by 956% in 2018 compared to the first half of 2017, cybersecurity firm Trend Micro reported on 29 August.
Over 787,000 crypto mining attacks were recorded in the first half of 2018, according to Trend Micro’s Midyear Security Roundup report, bearing in mind that in the same period of 2017, there were only 74,500 detections. These include both legal mining tools used in an incorrect and intentional manner.
According to the report, there have been identified “47 new cryptocurrency mining malware families,” meaning that new hackers appeared on the market rather than former ones resumed their malware.
Ransomware or Cryptojacking?
Throughout this period, hackers have targeted both businesses’ and individuals’ computers in order to mine cryptocurrencies, the report elaborates.
The report went on stating:
“From an enterprise point of view, the presence of unauthorized cryptocurrency miners in the network is a red flag not only for the affected individual user device but also for overall network security … The new challenge for enterprises lies in the fact that cryptocurrency miners are less visible, more silent threats, the non-detection of which is likely to induce a false sense of security.”
The report issued by Trend Micro follows the measures taken by other security research firms. As reported by Coindoo on 29 June, the Russian cybersecurity firm Kaspersky Lab found that hackers prefer cryptojacking rather than ransomware attacks.
“Kaspersky Lab has a tradition of reporting on the evolution of ransomware … This year, however, we came across a huge obstacle in continuing this tradition. We have found that ransomware is rapidly vanishing and that cryptocurrency mining is starting to take its place,” stated the report.
