Organizations worldwide are currently under a cyber-attack involving a new ransomeawre called “NotPetya”. The attack already hit Ukraine Central Bank and Russian oil giant Rosneft.
Ukraine Central Bank in a statement said “The National Bank of Ukraine has warned banks… about an external hacker attack on the websites of some Ukrainian banks… which was carried out today,” the bank said in a statement.
Banks were experiencing “difficulty in servicing customers and performing banking operations” due to the attacks, it said.
“All the financial market participants have taken steps to tighten security measures to counteract these hacker attacks,” it said, adding that “banking infrastructure is securely protected” and further attacks “will be efficiently warded off.”
Among the banks apparently affected was Oschadbank, one of Ukraine’s largest, it said on the website, forcing it to limit services available to clients.
Rosneft said on its twitter account that “A powerful hacking attack has been carried out against the company’s servers,”
Government computers, airports, and large communication companies in Ukraine appear to have been affected as well.
US¬†biopharmaceutical giant Merck also confirmed that its network has been compromised as part of the global attack.
“Kaspersky Lab’s analysts are investigating the new wave of ransomware attacks targeting organizations across the world. Preliminary findings suggest that it is not a variant of Petya ransomware as originally reported, but a new ransomware that has not been seen before,” the company said in a research note Tuesday afternoon. “That’s why we have named it NotPetya.”
