According to a new study, Monero (XMR) is by far the most common cryptocurrency among criminals who implement mining malware.
Two researchers, Sergio Pastrana and Guillermo Suarez-Tangil of Universidad Carlos III from Madrid and King's College of London, released their report last week, saying hackers took at least 4.32% of the total monero in circulation.
Pastrana and Suarez-Tangil write:
"Overall, we estimate there are at least 2,218 active campaigns that have accumulated about 720,000 XMRs ($ 57 million). It is interesting to note that only one campaign (C # 623) had more than 163,000 XMR ($ 18 million), which is approximately 23 % of the estimated total amount. This campaign is still active at the time of writing. "
Researchers, however, do not know for sure whether malicious software owners or some of them, have removed their crypts due to lack of information and fluctuating cryptographic prices. At the time of release, the value of the total quoted XMR is close to $ 40 million.
Approximately 4.4 million malware samples have been analysed for a period of 12 years, from 2007 to 2018, and a million malicious mines have been identified, according to the newspaper.
Tactics adopted for the distribution of malware are different, but a couple says "a common but effective approach to using legitimate infrastructure such as Dropbox or GitHub to host droppers and mining tools such as Claymore and Xmrig to perform the actual operation.
After the monster, both of whom have called the "predominant", bitcoin has come to another favourite crypto for illegal mining, although its popularity has declined over the years. Poor actors also experimented with other altcoins such as dogecoin or litecoin in 2013 and 2014, and then returned to bitcoin and monero, probably because they are more profitable, suggest researchers.
From the malware portfolios identified by the team, monero was 56 per cent more represented by bitcoin, while cash was in third place.
In November, a survey by Check Point Software Technologies, an Israeli cybersecurity company, showed that malicious mining software called KingMiner developed over time to avoid detection.
