Major Cyber Attacks, Data Breaches, Ransomware Attacks in January 2026

Written by Aditi Uberoi | 2 February 2026

January 2026 was a stark reminder that cyber risk is no longer confined to any single sector or geography. From global consumer brands to government agencies, healthcare providers, and education institutions, the month saw a relentless wave of cyber attacks, data breaches, and ransomware incidents that disrupted operations, exposed sensitive data, and tested organisational resilience.

The scale and diversity of victims underscored a sobering reality: no organisation is too big, too regulated, or too well-known to be targeted.

This month’s most significant incidents spanned cryptocurrency platforms, public sector bodies, healthcare networks, and household-name brands. High-profile breaches and attacks affected Trust Wallet, Higham School Lane, Illinois Department of Human Services, Brightspeed, Covenant Health, Kyowon Group, and Sedgwick Government Solutions—each highlighting different failure points, from credential misuse and third-party exposure to ransomware-driven operational paralysis.

Consumer brands were equally in the crosshairs. Incidents involving Under Armour, Nike, and Crunchbase reinforced how valuable customer data, brand trust, and digital platforms have become prime targets for attackers.

In this January 2026 cyber attack compilation, we break down what happened, how attackers gained access, and—most importantly—the lessons organisations can draw to strengthen their incident readiness, detection capabilities, and response strategies in an increasingly hostile threat landscape.
