Hollard data hits dark web after MIP hack

The dark web recently received stolen data from insurer Hollard after a cyber attack on its technology provider, MIP Group. The data breach is believed to be the work of a cyber crime group called “The Gentlemen”. Hollard had received a ransom demand from the group to prevent the public release of the data. A cybersecurity researcher confirmed that Hollard customer data had been made available on the dark web.

MIP Group reportedly paid an undisclosed sum to the hackers, who are now targeting their clients to extort money. The data leak follows a June cyber attack on MIP Group, which potentially exposed personal information linked to multiple financial services organisations. Hollard has notified customers who were affected by the June 2026 incident and is engaging with regulatory authorities.

The company advises customers to stay vigilant against phishing attempts and unsolicited communications. The Gentlemen, which emerged in mid-2025, is known for stealing sensitive data, encrypting victims' files, and demanding a ransom to recover the encrypted files, threatening to publish the stolen data if payment is not made.
