On this week’s Cyber Security Brief, Brigid O Gorman and Dick O’Brien discuss the latest Symantec blog, some updated research about the Yanluowang ransomware gang, with fresh activity appearing to show that this ransomware isn’t a flash-in-the-pan. We also discuss how quickly exposed cloud services are compromised by malicious actors, how off-putting strong passwords are for attackers employing brute-forcing techniques, and apparent attempts by Russian hackers to collaborate with Chinese-speaking actors. Also, the Conti gang’s possible role in the return of Emotet, and North Korean actors continue to target security researchers with fake job offers.
