	"plain_text": "Cyber insurer Chubb had data stolen in Maze ransomware attack\r\nBy Zack Whittaker\r\nPublished: 2020-03-26 · Archived: 2026-04-05 13:31:37 UTC\r\n12:31 PM PDT · March 26, 2020\r\nChubb, a major cybersecurity insurance provider for businesses hit by data breaches, has itself become a target of\r\na data breach.\r\nThe insurance giant told TechCrunch it was investigating a “security incident” involving the unauthorized access\r\nto data belonging to an unnamed third-party. Chubb spokesperson Jeffrey Zack said the company had “no\r\nevidence” the incident affected Chubb’s own network and that its network “remains fully operational.”\r\nBut the spokesperson declined to comment further or answer any of our questions, including if its customers were\r\naffected.\r\nBrett Callow, a threat analyst at security firm Emsisoft, first alerted TechCrunch to the breach on Thursday.\r\nAccording to Callow, the security incident was a data-stealing ransomware attack launched by the Maze\r\nransomware group. Maze not only spreads across a network, infecting and encrypting every computer in its path,\r\nit also exfiltrates the data to the attackers’ servers where it is held for ransom. If a ransom isn’t paid, the attackers\r\npublish the files online.\r\nIn December, the FBI privately warned businesses of an increase in Maze-related ransomware incidents.\r\nCallow said the attackers behind the incident posted a listing on their website claiming to have data stolen from\r\nChubb in earlier in March. The listing included the names and email addresses of three senior executives,\r\nincluding CEO Evan Greenberg.\r\nAt the time of writing, the attackers have not yet published any of the stolen files.\r\nTechcrunch event\r\nSan Francisco, CA | October 13-15, 2026\r\nChubb is one of the largest cybersecurity providers in the United States, offering incident response services and\r\ncovering companies from losses caused by data breaches. Target last year filed a $74 million lawsuit against\r\nChubb after the retailer claimed the insurance carrier failed to properly compensate it for the costs incurred from\r\nits 2013 data breach involving the theft of 110 million customers’ data.\r\nGot a tip?
