A Chinese‑linked threat group, active for about a year, has begun using Warlock ransomware to target large organisations in Spain and Portugal. The actor blends typical cybercrime motives with state‑associated techniques, creating a hybrid threat that challenges traditional defence models. This article breaks down the group's behaviour, its impact on Iberian businesses, and practical steps organisations can take to bolster resilience.

Financial institutions face a persistent standoff between security mandates and engineering realities. Every vulnerability remediation request collides with platform upgrade costs, regression testing burdens, and rigid change-freeze calendars. The result? Exceptions, compensating controls, and perpetually deferred fix dates that leave critical assets exposed. Breaking this cycle requires a fundamental shift: treating the software supply chain as a first-class production system rather than an afterthought. By embedding automated policy enforcement, continuous SBOM generation, and real-time provenance verification into the delivery pipeline, firms can eliminate entire vulnerability classes without grinding development to a halt.

The U.S. Cybersecurity and Infrastructure Security Agency has added a critical authentication bypass vulnerability in Cisco Catalyst SD-WAN Manager to its Known Exploited Vulnerabilities catalog. Tracked as CVE-2026-76504 with a CVSS score of 9.8, the flaw allows unauthenticated remote attackers to compromise affected systems. Federal agencies now face a mandatory remediation deadline as threat actors actively exploit this weakness in the wild.

Google has introduced Gemini 4 Argon, its newest frontier artificial intelligence model, which is now being distributed to a select group of trusted cyber defenders through the company’s Fairwind Program. According to Google, the model excels in handling complex workflows across domains such as software engineering, legal, finance, and cybersecurity defense. This rollout signals a major step forward in AI-assisted cyber operations, but also sparks discussions around safety protocols and the implications of future guardrail-free deployments.

LevelBlue THOR team has identified a critical post-exploitation technique targeting Citrix NetScaler infrastructure. Threat actors leverage a pre-authentication command injection flaw to establish remote access, drop malicious web shells, and attempt theft of sensitive configuration data across enterprise networks.

A new wave of attacks leverages OpenAI's Custom GPT feature to distribute remote access trojans through deceptive ClickFix-style lures. By abusing legitimate OpenAI and Google domains, threat actors create convincing traps that bypass traditional security controls and exploit user trust in AI platforms. Security researchers have identified campaigns where malicious GPTs prompt users to execute PowerShell commands under the guise of fixing technical issues, ultimately deploying malware that grants attackers full system control. This evolution in social engineering demonstrates how generative AI tools are being repurposed as delivery mechanisms for sophisticated payloads.

The surge of artificial intelligence is fundamentally reshaping the security operations center (SOC) career ladder, delivering higher job satisfaction for the majority of defenders while simultaneously making entry into the field more challenging for almost half of newcomers. Recent research from Swimlane highlights a paradox: AI‑powered detection and response tools give analysts a decisive edge, yet a quarter of security professionals feel that reliance on automation curtails their opportunities for skill growth.

Attackers are exploiting the legitimate MSP360 Remote Monitoring and Management tool to gain unauthorized access through deceptive phishing emails. By masquerading as meeting invitations, PDF documents, and software updates, malicious actors trick users into executing a seemingly benign installer that opens a backdoor for further compromise, including the deployment of secondary remote management solutions like ScreenConnect. This dual‑RMM approach allows attackers to maintain persistence and move laterally within targeted networks.

Cisco has disclosed that threat actors are actively exploiting a critical authentication bypass vulnerability in Catalyst SD-WAN Manager. Tracked as CVE-2024-76504, the flaw allows unauthenticated remote attackers to assume administrative privileges via the management API. With no available workaround, organizations must apply patches immediately to prevent full compromise of their SD-WAN infrastructure.

Security researchers at Huntress have uncovered a novel campaign where threat actors weaponize ChatGPT Custom GPTs as lures to redirect victims to malicious infrastructure employing ClickFix tactics. This attack chain ultimately deploys a Remote Access Trojan, marking a significant escalation in the abuse of trusted AI platforms for initial access.
