랜섬웨어는 2020 년보다 2.5 배 더 많은 수익을 올렸습니다.
The financial damage to the victims increased from $760,000 to $1.85 million. However, only 8 companies that paid the hackers were able to recover the data
According to a Sophos survey of 5,400 companies, more than 37% of them were attacked by ransomware in the four months of 2021. In 2020, 51% of break-ins were in a full year.
Financial losses almost tripled. The report only took into account the funds paid to the extortionists as ransom. Damage due to downtime and other factors was not taken into account.
According to Sophos, the average loss from the ransomware attack was 170.4 thousand dollars. At the same time, not everyone managed to recover their data.
Although, it is worth noting that the attackers do not always use encryption when attacking ransomware. Some companies paid a ransom for not disclosing confidential information. The number of such cases increased from 3 to 7 per cent from 2020 to 2021.
The essence of the problem is the location of the attacker's vulnerability, gaining access to information (site, computer) and data encryption. At the same time for deciphering scammers demand Bitcoins or more anonymous cryptocurrencies Monero, etc.
It is believed that cryptocurrencies are difficult to track. However, the attackers are even more cautious. They use various payment mixers to obfuscate the trace of the funds received to prevent the discovery of the recipient of the cryptocurrency.
