The Maze ransomware operators, who were reportedly behind the recent attack on Cognizant, claimed to have got their hands on 11 million credit card credentials belonging to the network of Banco BCR, a state-owned Bank of Costa Rica. They also leaked some 240 credit card details on their site as proof of the theft. However, this time, the operators did not seem to be focused on monetizing the stole data themselves and instead wanted to highlight the security flaw in the bank’s network.

A sophisticated phishing campaign called PerSwaysion, that has targeted more than 150 companies around the world, has also been observed in the past 24 hours. Cybercriminals behind the campaign relied on Microsoft Sway service and phishing kits to steal credentials from Microsoft Office 365 users. Another spear-phishing attack was also observed targeting government employees of the Municipality of Da Nang, Vietnam. The intended victims were sent emails with ‘danang.gov.vn’ appended to the sender’s address.
