Black hat hacker group, Maze, claims to have used ransomware to compromise the systems of insurance giant, Chubb. They also claim to have stolen the firm’s data.
Brett Callow, threat analyst at cybersecurity firm, Emsisoft, told Cointelegraph on March 27 that Maze published the claim on its website. While the website does not provide any direct proof of the hack so far, Callow pointed out facts that give the claim an air of credibility:
“Maze’s past victims include governments, law firms, healthcare providers, manufacturers, medical research companies, healthcare providers and more.”

News.com.au reported that Australian Prime Minister Scott Morrison has announced that Australia is being hit with a massive cyber attack by a sophisticated foreign “state-based” hacker.
“In an urgent press conference called this morning in Canberra, Mr Morrison said the ongoing, “large-scale” hack was being executed by a “sophisticated, state-based cyber actor”.
“This activity is targeting Australian organisations across a range of sectors, including all levels of government, industry, political organisations, education, health, essential service providers and operators of other critical infrastructure,” Mr Morrison told reporters.
“We know it is a sophisticated, state-based cyber actor because of the scale and nature of the targeting and the tradecraft used. Regrettably, this activity is not new. Frequency has been increasing.”
