The report also reveals that a total of $706,452 was paid as ransom to the cybercriminals by Nigerian businesses in the year. The average cost of rectifying cyber-attack in the country also went up from $0.46 million in 2020 to $3.43 million in 2021.
According to the report published by Nairametrics,Forty-four per cent of the organisations that had data encrypted paid the ransom to get their data back, even when they had other means of data recovery, such as backups.
Commenting on the report which was a product of a survey conducted by the company, Principal Research Scientist at Sophos, Chester Wisniewski, said: “The survey shows that, globally, the proportion of victims paying the ransom continues to increase, even when they may have other options available,”
“There could be several reasons for this, including incomplete backups or the desire to prevent stolen data from appearing on a public leak site. In the aftermath of a ransomware attack there is often intense pressure to get back up and running as soon as possible. Restoring encrypted data using backups can be a difficult and time-consuming process, so it can be tempting to think that paying a ransom for a decryption key is a faster option.
“It’s also an option fraught with risk. Organisations don’t know what the attackers might have done, such as adding backdoors, copying passwords and more. If organizations don’t thoroughly clean up the recovered data, they’ll end up with all that potentially toxic material in their network and potentially exposed to a repeat attack.”
