Infosys McCamish Systems Ransomware Attack: Over Six Million Customers' Data Compromised

Introduction

A significant ransomware attack on Infosys McCamish Systems, an outsourcing service provider for financial and insurance companies, has impacted over six million customers. The breach, which took place in late 2023, was only recently disclosed in a filing with the Maine Office of the Attorney General (OAG). This incident underscores the importance of robust cybersecurity measures such as stolen credentials detection, darknet monitoring services, and digital footprint analysis.

Incident Overview

The cyber-attack occurred between October 29 and November 2, 2023, according to a comprehensive cyber forensic investigation. The stolen data includes sensitive personal information such as Social Security Numbers, dates of birth, medical records, biometric data, email addresses, usernames, passwords, Driver’s License numbers, financial account details, payment card information, passport numbers, tribal IDs, and US military IDs.

Initial Discovery and Response

Infosys McCamish Systems (IMS) first reported the incident in February, but customers were not notified until June 27, 2024. This delay was due to an exhaustive review conducted with the assistance of third-party eDiscovery experts. The review aimed to identify the compromised personal information and notify affected individuals and organizations.

Impact and Mitigation

IMS is offering 24 months of credit monitoring to affected customers. Although there is no evidence yet of fraudulent use of the stolen information, the risk of follow-on phishing and identity fraud attacks remains high. The attack, attributed to the notorious ransomware group LockBit, involved encrypting over 2,000 computers, further highlighting the need for strong cybersecurity defenses like digital threat scoring and online risk evaluation.
