Emerging sophisticated cyberattack campaigns have become a major cause of headache for cyber defenders. A massive spear-phishing campaign, which is believed to have been active since 2018, has finally come under the radar of security researchers. The campaign, backed by the notorious Lazarus threat actor group, has so far targeted the cryptocurrency vertical in more than 14 countries.
That’s not all. A recently discovered DarkSide ransomware has claimed its attacks on Brookfield Residential by stealing confidential information from the firm. The operators have threatened to leak all the stolen files and documents on a website if their ransom demand is not met.
A new phishing attack against Microsoft Office 365 users was also observed in the last 24 hours. The attack, which was primarily aimed at government and security organizations, was executed using a legitimate Box webpage as a bait.
