The number of “cryptojacking” cases across the financial sector has risen by 269% in the first half of 2022, according to a report by cybersecurity firm SonicWall.
-
Cryptojacking is a type of cyberattack where hackers implant a piece of software on a victim’s computer that mine cryptocurrencies. Victims are often unaware of the exploit, which has contributed to the rise in cases, the report said.
-
In previous years, government, healthcare and education sectors were the most common targets for cryptojacking, however there has been a “dramatic reshuffling” in 2022.
-
“Cryptojacking targeting the retail industry increased 63% year-to-date, while attacks on the financial industry skyrocketed 269%,” the report states.
-
The number of attacks on the finance industry is now five times greater than retail, which is second highest.
-
The rise has also been attributed to a decline in ransomware attacks, which is also caused by increased interest of cryptocurrency-related cyberattacks coupled with more stringent insurance processes around ransomware.
-
“It [cryptojacking] has a lower potential of being detected by the victim; unsuspecting users across the world see their devices get unaccountably slower, but it’s hard to tie it to criminal activity, much less point to the source,” Terry Greer-King, SonicWall vice president for EMEA, told Tech Monitor.
