This week I’m writing about some recent cybersecurity instances I found interesting and what some of their impacts are,
National Defense Corporation Ransomware
In March 2025, 4.2 tb worth of sensitive data was taken.
While this information proved to be directly classified it still rose eyebrows around the world about the safety of defense corporations.
The attack marked a shift in Interlock’s targeting strategy from broad, opportunistic campaigns to high-value defense contractors. Though classified data wasn’t directly exposed, procurement documents, logistics details, and supply chain information were compromised, creating long-term risk across the defense industrial base (DIB).
Compliance frameworks like CMMC 2.0 are critical for protecting sensitive, unclassified data, requiring defense contractors and subcontractors to implement robust access controls, encryption, and continuous monitoring, among other controls.
In the end nothing of note was pressed toward the individuals who hacked the corporation, Further investigations have followed since into the leak of crucial information to the dark web and what repercussions will follow of said information.
The national defense corporation has a strong protection plan put into place to prevent circumstances like this occuring so it remains to be seen on further details as to how the information was exposed to the dark web. Further investigations are ongoing into the sensitive data but as of now nothing of note was leaked.
“This incident emphasizes the importance of ensuring, even if you’re compliant yourself, that your entire supply chain, including third- and fourth-party vendors, meets similar security standards.”
Microsoft zero day
In April 2025, Ransomware attacks via CLFS zero-day vulnerability on organizations across the globe. In April, Microsoft patched 126 vulnerabilities, including CVE-2025-29824, a zero-day flaw in the Windows Common Log File System (CLFS) exploited by the group Storm-2460. The attackers used a custom malware strain, PipeMagic, to escalate privileges and launch ransomware across multiple sectors worldwide.
While the entry point remains unclear, Microsoft confirmed the vulnerability allowed attackers with standard user access to gain elevated privileges, a key step in post-compromise ransomware deployment. The CLFS vulnerability is part of a growing trend of privilege escalation flaws being actively exploited, according to Satnam Narang, senior staff research engineer at Tenable. “Elevation of privilege flaws in CLFS have become especially popular among ransomware operators over the years,” Narang said. “While remote code execution flaws are consistently top overall Patch Tuesday figures, the data is reversed for zero-day exploitation. For the past two years, elevation of privilege flaws have led the pack and, so far in 2025, account for over half of all zero-days exploited.”
With this information we can infer that microsoft has also since patched this vulnerability as it led to a large portion of their internal network becoming corrupted in the months that followed. While the individuals have been identified nothing of note was listed that legal action was taken against the group known as Storm-2460 so it remains to be seen if the group or individual still remains at large leaking information or important documentation around Microsoft.
