BI’s Article search uses Boolean search capabilities. If you are not familiar with these principles, here are some quick tips.
To search specifically for more than one word, put the search term in quotation marks. For example, “workers compensation”. This will limit your search to that combination of words.
To search for a combination of terms, use quotations and the & symbol. For example, “hurricane” & “loss”.
(Reuters) — Global ransomware attacks increased by 151% in the first half of 2021 compared with 2020 and hackers are set to become increasingly aggressive, Canada's signals intelligence agency said Monday.
The Communications Security Establishment, citing attacks on North American health facilities and a U.S. pipeline, said the scale and scope of ransomware operators represented both security and economic risks to Canada and its allies.
“Ransomware operators will likely become increasingly aggressive in their targeting, including against critical infrastructure,” said a report issued by the Canadian Centre for Cyber Security, a unit of CSE.
The agency said it knew of 235 ransomware incidents against Canadian victims from Jan. 1 to Nov. 16 this year. More than half of these victims were critical infrastructure providers.
In 2021, the global average total cost of recovery from a ransomware incident has more than doubled to C$2.3 million ($1.8 million).
“Ransom payments are likely reaching a market equilibrium, where cybercriminals are becoming better at tailoring their demands to what their victims are most likely to pay,” CSE said.
The agency reiterated previous statements that actors in Russia, China and Iran posed a major threat.
