Threat Intelligence / Cybersecurity
Attackers are no longer waiting for patches; they are infiltrating systems before defenses are in place. Trusted security tools are being compromised to spread malware. Even after breaches are detected and addressed, some attackers remain undetected. This week’s incidents highlight a stark reality: reactive measures are insufficient. You must operate under the assumption that any system you trust today could fail tomorrow. In a landscape where AI can be weaponized against you and ransomware strikes faster than ever, effective protection requires proactive planning and maintaining control amidst chaos.
Dive into this week’s update for crucial threat developments, insightful webinars, practical tools, and immediate tips to enhance your cybersecurity posture.

Vulnerability / Email Security
A cyber espionage operation associated with a Russian threat actor is reportedly compromising webmail servers, including Roundcube, Horde, MDaemon, and Zimbra, by exploiting cross-site scripting (XSS) vulnerabilities, notably a zero-day flaw in MDaemon. This activity, coded as Operation RoundPress by ESET, began in 2023 and has been linked with moderate confidence to the state-sponsored hacking group APT28, also known by various names such as BlueDelta, Fancy Bear, and Sednit.
“The primary objective of this operation is to extract sensitive data from targeted email accounts,” stated ESET researcher Matthieu Faou in a report shared with The Hacker News. “While most victims are governmental and defense entities in Eastern Europe, we have also noted targets across Africa, Europe, and beyond.”

The Iranian nation-state group MuddyWater has been implicated in conducting destructive operations on hybrid environments while masquerading as a ransomware campaign. According to new insights from the Microsoft Threat Intelligence team, these threat actors are targeting both on-premises and cloud infrastructures, often collaborating with a recently identified cluster known as DEV-1084. “Despite efforts to present their activities as a typical ransomware operation, the irreversible damage they inflict indicates that destruction and disruption were their primary objectives,” the company reported on Friday. MuddyWater is linked to Iran’s Ministry of Intelligence and Security (MOIS) and has been active at least since 2017, also recognized by various names in the cybersecurity field, including Boggy Serpens.

Critical RCE Vulnerability in Gladinet’s Triofox and CentreStack Actively Exploited
A recent security flaw in Gladinet CentreStack is also affecting its Triofox remote access solution, as revealed by Huntress. To date, seven organizations have been compromised due to this issue, tracked as CVE-2025-30406 (CVSS score: 9.0). The vulnerability stems from a hard-coded cryptographic key that exposes internet-accessible servers to remote code execution (RCE) attacks. It has been patched in CentreStack version 16.4.10315.56368, released on April 3, 2025. Although the exact nature of the attacks remains unclear, they reportedly exploited a zero-day variant in March 2025. According to Huntress, the flaw also affects Triofox up to version 16.4.10317.56372, as its previous versions contain the same hard-coded cryptographic keys, making them susceptible to RCE exploits, as noted by John Hammond, principal cybersecurity researcher at Huntress.

Hardware Security / Vulnerability
Researchers at ETH Zürich have identified a critical new security flaw that affects all modern Intel CPUs, allowing the leakage of sensitive data from memory. This latest vulnerability, dubbed Branch Privilege Injection (BPI), showcases that the Spectre threat continues to impact computer systems over seven years after its initial discovery. According to ETH Zürich, BPI can be exploited to manipulate the CPU’s prediction calculations, granting unauthorized access to information from other users on the same processor. Kaveh Razavi, head of the Computer Security Group (COMSEC) and a co-author of the study, noted that this flaw affects all Intel processors, potentially allowing malicious actors to access the cache contents and working memory of different users sharing the CPU. The attack exploits Branch Predictor Race Conditions (BPRC), which arise when a processor alternates between prediction calculations for multiple users.
