Major Data Breaches
Nike Investigates Massive Data Breach by WorldLeaks
Nike, the global athletic giant, is investigating a significant data breach after the WorldLeaks ransomware group claimed to have exfiltrated 1.4 terabytes of sensitive internal data. The breach, which came to light on January 22, 2026, reportedly includes over 188,000 files containing intellectual property such as design schematics for the upcoming Jordan Brand SP27 collection, product tech packs, supply chain details, and internal documents spanning 2020 to 2026. WorldLeaks, a rebrand of the notorious Hunters International, has shifted from ransomware encryption to pure data theft and extortion, threatening to release the stolen files unless paid. Nike has acknowledged the incident and is actively assessing the situation. The exposure of future product designs and strategic documents poses a significant risk to Nike’s competitive edge and could lead to counterfeiting and market share erosion1.

Crunchbase Data Breach
Crunchbase, a leading business intelligence platform, confirmed a data breach after the cybercriminal group ShinyHunters claimed responsibility. Over 2 million user records were reportedly stolen, with a 400MB dataset publicly leaked after ransom demands were not met. The exposed data includes both personal and business-related information, highlighting how even “non-sensitive” data can become sensitive once exfiltrated2.

ICE and CBP Employee Data Leak
Sensitive personal data linked to approximately 4,500 employees of U.S. Immigration and Customs Enforcement (ICE) and Customs and Border Protection (CBP) was exposed in January 2026. Early reports suggest this was an insider-related data leak rather than an external cyberattack, underscoring the growing risk of internal data misuse and access abuse within complex organizations2.
Ingram Micro Ransomware Attack
Ingram Micro, a major IT distributor, suffered a ransomware attack that resulted in the theft of personal information belonging to 42,521 employees and job applicants. The attack, attributed to the SafePay ransomware group, exploited compromised credentials and password-spraying attacks to breach internal systems. Exfiltrated data included names, contact information, government-issued IDs, and employment records. Ingram Micro responded by enhancing security and monitoring measures3.

Significant Cyberattacks
European Space Agency (ESA) Massive Cyberattack
The European Space Agency (ESA) faced a series of cyberattacks in late 2025 and early 2026, resulting in the theft of over 700GB of data. Attackers stole proprietary software, credentials, mission documents, and more, later sharing them on the dark web. The breaches affected external servers used for collaborative engineering, but the leaked material included source code, API tokens, and confidential documents. A second group, Scattered Lapsus$ Hunters, claimed to have stolen an additional 500GB of data, including operational procedures and contractor information from aerospace giants like SpaceX and Airbus. These incidents highlight the vulnerability of even elite research organizations to modern cyber threats4.

Luxshare Ransomware Attack
RansomHub, a ransomware group, claimed responsibility for an attack on Luxshare, a key manufacturing partner for Apple, Nvidia, and Tesla. Attackers reportedly accessed engineering schematics and technical documents, reflecting the continued rise of supply chain cyberattacks targeting vendors and partners embedded in critical ecosystems2.
Microsoft Misconfigured Server Data Exposure
Security researchers disclosed a 2.4-terabyte data exposure tied to a misconfigured Microsoft server. The incident, discovered and remediated in January 2026, resulted from cloud configuration errors rather than advanced exploits, reinforcing the risks posed by operational mistakes2.
Critical Vulnerabilities
Microsoft Patch Tuesday: 114 Flaws, 3 Zero-Days
On January 13, 2026, Microsoft released security updates addressing 114 vulnerabilities, including three zero-day flaws. Notably, CVE-2026-20805, a Desktop Window Manager (DWM) information disclosure vulnerability, is being actively exploited in the wild. Despite a CVSS score of 5.5, experts warn that this flaw can be chained with other exploits to bypass core OS security controls. Other critical vulnerabilities patched include remote code execution bugs in Office (CVE-2026-20952, CVE-2026-20953) and LSASS (CVE-2026-20854). Rapid patching is strongly advised, especially for internet-facing systems5.

Cisco Zero-Day (CVE-2026-20045) in Unified CM and Webex
Cisco released urgent patches for a critical zero-day vulnerability (CVE-2026-20045, CVSS 8.2) affecting Unified Communications products and Webex Calling Dedicated Instance. The flaw allows unauthenticated remote attackers to execute arbitrary commands and escalate privileges to root. Cisco confirmed active exploitation in the wild, and CISA added the vulnerability to its Known Exploited Vulnerabilities catalog, requiring federal agencies to patch by February 11, 2026. No workarounds are available; immediate upgrades are recommended6.

Oracle Critical Patch Update: 337 New Security Patches
Oracle’s January 2026 Critical Patch Update (CPU) delivered 337 new security patches across more than 30 products, addressing roughly 230 unique CVEs. Over two dozen critical-severity vulnerabilities were fixed, including remotely exploitable flaws in Oracle Communications, Fusion Middleware, and MySQL. Notably, several patches address CVE-2025-66516 (CVSS 10.0), a critical Apache Tika defect that could lead to XML External Entity (XXE) injection attacks. Oracle strongly urges customers to apply updates without delay7.

Miscellaneous
Cybersecurity Conferences
Several major cybersecurity conferences are scheduled for late January and early February 2026, including the International Conference on Applied Cryptography and Network Security (ICACNS) in Las Vegas and New York, and the Cybersecurity, Stronger Together Conference at George Washington University. These events focus on converging threats, shared defenses, and the evolving landscape of AI and cyber risk1011.

Industry Trends
Analysts warn that 2026 will be shaped by a convergence of long-running threats, intensified by rapid AI adoption and shifting government priorities. Ransomware remains the dominant risk for local governments and K-12 systems, while supply chain attacks and insider threats are on the rise. The growing mismatch between the pace of AI adoption and regulatory oversight is a key concern for the year ahead12.
