Top insurance providers in Hawaii. Since 1958,Mutual Underwriters have provided insurance to folks in Hawaii and have expanded our services to include every type of insurance whether it's for your home, vehicle or family health. We also offer insurance for commercial needs. Over 700GB of personal data were stolen from there, including: - detailed insurance information (name of insured, amount of payments, contacts, address, etc) - financial data (transfers, payments, etc) - access to insurance providers applications (with possibility to manage insurances) - employees personal details (contacts, payments, passwords to personal services, etc) - other sensitive data elated to customers and employees which supposed to be protected Unfortunately for ordinary people the top management of Mutual Underwriters offered only "words" to protect their data. This sum is unacceptable. Since all the time needed for their bosses to make a decision were given and all the evidences were provided, Mutual Underwriters decided to stop the negotiation process, you can find all the data stolen from them for free download now.

No regulatory filing corroborates this yet — it is the attacker's own assertion. Watch this entity to be notified the moment a filing corroborates or contradicts it.

According to ransomware.live, The operators of the ALPHV/BlackCat ransomware began their activity in December 2021, making posts on Dark Web forums to promote their affiliate program, offering other actors the opportunity to engage in a 'new type of ransomware family' developed from scratch using the Rust programming language. Some clear evidence indicates that the actors behind this new ransomware are not new to cybercrime, and there were links to other affiliate programs such as DarkSide, BlackMatter, and REvil. (After several attacks against large companies, these groups faced pressure and arrests, necessitating the termination of their operations). As a security measure, the operators of ALPHV implemented the requirement for the execution of the ransomware payload by providing an 'access token,' which is supplied by the owners of the Ransomware-as-a-Service to the affiliate. This token is added to the victim's ransom note so that they can contact the threat actor responsible for encrypting the data. ALPHV affiliates employ double and triple extortion techniques, meaning the publication of the company's name on leak sites, threats of data leakage, and lastly, threats of DDoS attacks against the organization.
