In January, a new wave of hackers launched a major attack against banks and other financial institutions around the world, using a new strain of ransomware that stole a significant amount of money from financial institutions.
The ransomware attack is believed to have been aimed at banking institutions and was aimed at crippling those systems with the ransomware in the hopes of forcing them to shut down.
The attacks also affected financial institutions across the world.
In February, the Financial Security Board of Canada and the National Bank of Canada warned that they were considering additional sanctions against financial institutions for failing to secure their networks, as well as other measures to mitigate the risk of the ransomware.
In June, the U.S. Federal Reserve issued a warning that the ransomware could cause financial systems to crash, which is not a new threat for banks.
While the attacks hit many financial institutions in different countries, the most affected was the European Union.
The bank of Belgium, which had the highest proportion of banks affected by the ransomware attack, said it was forced to shut its computer systems down for several hours on June 24, 2017.
The banks are notifying customers to change passwords and have also issued a statement warning people about possible ransomware attacks and their importance to their businesses.
The U.K. Financial Services Authority said that it was investigating a report that the banks were facing a cyber-attack by a cybercriminal group.
