Operation Zero Disco: APTs Weaponize Cisco SNMP Flaw to Deploy Linux Rootkits
In early October 2025, security researchers uncovered Operation Zero Disco, a targeted cyber campaign leveraging a stack overflow vulnerability (CVE-2025-20352) in Cisco IOS and IOS XE software. Advanced persistent threat (APT) actors weaponized this SNMP flaw to access legacy Cisco networking equipment, deploying covert Linux rootkits and securing long-term persistence on compromised devices. The exploitation enabled attackers to bypass standard defenses, facilitate lateral movement, and maintain undetected access to sensitive east-west network traffic, significantly increasing risk for organizations relying on outdated infrastructure. This incident highlights a growing trend of sophisticated actors exploiting unpatched or unsupported networking systems to achieve deep infrastructure compromise. With the resurgence of supply chain and infrastructure-based attacks, persistent network vulnerabilities demand heightened vigilance, rapid patch adoption, and robust segmentation. Industry-wide, there is mounting urgency to secure critical areas exposed by legacy systems and evolving attacker tactics.

Inside the LinkPro Linux Rootkit: eBPF Backdoors AWS Cloud in 2025
In October 2025, security researchers from Synacktiv revealed the discovery of LinkPro, a sophisticated GNU/Linux rootkit targeting AWS-hosted infrastructure. The attackers leveraged advanced eBPF techniques to install two modules: one for stealth, allowing the malware to evade detection, and another granting remote access via specially crafted TCP packets (magic packets). This backdoor enabled threat actors to persist undetected, hide their presence, and maintain control of compromised systems in cloud environments, posing severe risks to the underlying business operations and data confidentiality of affected organizations. This incident highlights the escalating use of kernel-level and cloud-specific attack techniques, exploiting eBPF to bypass traditional defenses. The campaign underscores a growing trend of attackers utilizing cloud-native technologies to achieve stealth and persistence, raising urgent concerns for CISOs overseeing both public cloud and Linux workloads.

How UNC5142 Hijacked WordPress & Blockchain for Next-Gen Stealer Attacks (2025)
In October 2025, threat actor UNC5142 leveraged compromised WordPress sites to distribute a wave of information-stealing malware using an innovative attack method dubbed 'EtherHiding.' The adversaries abused blockchain-based smart contracts to conceal malicious code, enabling malware such as Atomic Stealer, Lumma, Rhadamanthys, and Vidar to infect both Windows and macOS endpoints. This technique allowed attackers to rapidly update payloads beyond the reach of static blocklists and frequently evade traditional security controls. Victims included a variety of enterprises and individuals, with attackers capitalizing on the popularity and trust of infected WordPress content management platforms. This incident highlights an emerging TTP where blockchain infrastructure is repurposed to enhance delivery persistence and obfuscation for criminal campaigns. The rapid uptake of such blockchain-based methods demonstrates the need for organizations to evolve threat detection and response strategies as attackers diversify beyond conventional web infrastructure.

Cursor & Windsurf IDEs Hit by 94+ Chromium Vulnerabilities – Supply-Chain Exposure in 2024
In early 2024, security researchers identified that the latest releases of the Cursor and Windsurf integrated development environments (IDEs) were vulnerable to over 94 known and patched security vulnerabilities within the embedded Chromium browser and V8 JavaScript engine. These n-day vulnerabilities exist because the IDEs relied on outdated Chromium builds, exposing users to a range of critical issues, including remote code execution, privilege escalation, and data leakage. The supply-chain nature of the incident means development teams using these IDEs could inadvertently introduce risk across their entire workflow and environments. This incident underscores the persistent risk posed by vulnerable software dependencies and highlights an urgent need for improved supply-chain security. With attackers increasingly targeting development tools for initial access or lateral movement, organizations must re-evaluate their patch management, vendor risk assessments, and layered network protections.

CISA Flags Oracle E-Business Suite SSRF Exploitation: What You Need to Know
In June 2024, the Cybersecurity and Infrastructure Security Agency (CISA) confirmed that threat actors exploited a critical Server-Side Request Forgery (SSRF) vulnerability, CVE-2025-61884, in Oracle E-Business Suite. Attackers leveraged this zero-day flaw to gain unauthorized access to internal systems, potentially allowing data exposure or further lateral movement within affected organizations. The vulnerability has since been added to CISA's Known Exploited Vulnerabilities catalog, highlighting active exploitation in the wild and prompting urgent remediation efforts across the private and public sectors. This incident underscores the growing trend of exploiting SSRF flaws in enterprise applications to bypass perimeter controls and facilitate initial access. Regulatory agencies globally are increasing pressure on vendors and businesses to patch critical application vulnerabilities rapidly as attacker sophistication and exploitation speed accelerate.

Critical Command Injection Flaw Found in TP-Link Omada Gateways (2024)
In June 2024, TP-Link disclosed a critical security vulnerability (CVE-2024-5035) affecting several Omada gateway models. The flaw is a pre-authentication operating system command injection that could allow remote, unauthenticated attackers to execute arbitrary commands on vulnerable devices, compromising the integrity and availability of network infrastructure. TP-Link quickly released firmware patches, urging customers to update immediately. This exposure heightened the risk of unauthorized access to internal networks, potentially leading to data breaches, lateral movement, or infrastructure disruption for organizations reliant on impacted Omada devices. The incident underscores an ongoing trend of targeting network infrastructure via supply chain or firmware vulnerabilities, which have become increasingly prevalent as attackers seek to exploit core networking hardware. This highlights the need for vigilant patch management and segmentation in defense strategies, as well as resilience against emerging firmware and gateway attacks.

North Korean Hackers Employ EtherHiding for Unprecedented Cryptocurrency Heist
In October 2025, threat group UNC5342—attributed to North Korea—executed an advanced cryptocurrency theft operation by leveraging the novel EtherHiding technique. Attackers embedded malicious code within blockchain smart contracts to distribute malware, evading conventional detection mechanisms. Google Threat Intelligence Group (GTIG) identified this as the first known use of EtherHiding by a state-sponsored actor, resulting in the covert compromise of multiple cryptocurrency platforms and significant asset loss. The incident underscores an evolving trend: nation-state actors are adopting increasingly sophisticated blockchain-based attack methods. With rising blockchain adoption, such TTPs present serious risks for organizations involved in digital assets, regulation, and financial technology.

Microsoft Revokes Fraudulent Certificates Exploited by Rhysida Ransomware in 2025 Campaign
In June 2025, Microsoft discovered and responded to a sophisticated campaign in which a threat actor known as Vanilla Tempest (also tracked as Storm-0785) fraudulently issued over 200 code-signing certificates. These certificates were leveraged to make malicious files appear legitimate, facilitating the distribution of a fake Microsoft Teams installer that ultimately delivered the Oyster backdoor and deployed Rhysida ransomware across targeted environments. Microsoft quickly moved to revoke all compromised certificates to mitigate the risk and prevent further exploitation by the attackers. The breach highlights the growing sophistication of ransomware groups in leveraging trusted supply chain components for malware delivery. This incident underscores the heightened threat landscape in which adversaries exploit trusted relationships and digital certificates to evade security controls. It also signals an increasing trend of ransomware utilizing living-off-the-land and supply chain abuse techniques, compounding challenges for organizations striving to maintain software integrity and regulatory compliance.
