Critical Threats

Lazarus Group Executes $1.5 Billion Crypto Heist via Supply Chain Attack

    North Korean state-sponsored actors (Lazarus) successfully compromised the Bybit cryptocurrency exchange through a sophisticated supply chain attack, stealing over 400,000 ETH. This represents the largest single theft in the sector for 2025/2026, demonstrating the group's persistent capability to breach major financial platforms.

    Business Impact

    For financial and crypto-adjacent organizations, this highlights extreme supply chain risk. A successful attack results in massive immediate financial loss, potential insolvency, irreversible reputational damage, and intense regulatory scrutiny.

    Recommended Action

    Ask your CISO: "Have we audited the security posture of our third-party software providers recently, specifically those with access to financial transaction layers?"

Google Patches Actively Exploited Chrome Zero-Day (CVE-2026-2441)

    Google has released an emergency update for Chrome to address CVE-2026-2441, a high-severity vulnerability currently being exploited in the wild. This flaw allows attackers to execute arbitrary code on a victim's machine simply by having them visit a malicious website.

    Business Impact

    This is a "drop everything" patch event. If left unpatched, any employee browsing the web could inadvertently grant attackers access to the corporate network, leading to ransomware deployment or data theft.

    Recommended Action

    Ask your IT Director: "Can we verify that 100% of our browser fleet has been updated to version 145 or higher as of this morning?"

The Promptware Kill Chain: New Attacks Targeting Generative AI

    Security researchers have defined a new kill chain for "Promptware" attacks, where malicious inputs are used to manipulate Large Language Models (LLMs) into executing unauthorized actions. This coincides with reports of CVE-2026-25253 affecting AI agent runtimes like OpenClaw.

    Business Impact

    As companies integrate AI agents into business workflows, these vulnerabilities can allow attackers to hijack the AI to exfiltrate sensitive data, generate malicious code, or perform unauthorized transactions on behalf of the company.

    Recommended Action

    Ask your AI/Data team: "What guardrails do we have in place to prevent prompt injection attacks against our internal AI tools?"

CISA Adds BeyondTrust Vulnerability to Known Exploited Catalog

    CISA has added a critical flaw in BeyondTrust Remote Support (RS) and Privileged Remote Access (PRA) to its Known Exploited Vulnerabilities (KEV) catalog. Attackers are actively using this vulnerability (CVE-2026-1731) to compromise remote access tools used by IT administrators.

    Business Impact

    Compromise of remote support tools gives attackers the "keys to the kingdom," allowing them to bypass perimeter defenses and move laterally with administrative privileges. This often leads to full domain compromise.

    Recommended Action

    Ask your Security Operations team: "Do we use BeyondTrust, and if so, have we applied the patches mandated by the CISA KEV alert for CVE-2026-1731?"

High Severity

ClickFix Campaign Weaponizes nslookup for RAT Delivery

    A new "ClickFix" social engineering campaign is tricking users into running malicious `nslookup` commands to download Remote Access Trojans (RATs). This technique bypasses some traditional browser protections by moving the execution to system tools.

    Business Impact

    This increases the success rate of phishing attacks. If an employee falls for this, attackers gain remote control of their workstation, potentially leading to data breaches or ransomware entry.

    Recommended Action

    Ask your SOC: "Can our endpoint detection systems identify and block unusual `nslookup` commands that attempt to download external payloads?"

    General Enterprise Malwarebytes ↗

The US Cybersecurity and Infrastructure Security Agency (CISA) is operating at 38% capacity due to a DHS shutdown. This reduces the agency's ability to respond to incidents and issue timely alerts.

Business Impact

Organizations relying on CISA for real-time threat intelligence or incident response support should expect significant delays. Self-reliance for threat monitoring is currently critical.

Recommended Action

Ask your Threat Intel team: "Are we monitoring alternative intelligence sources to compensate for potential delays in CISA advisories?"

Lasso Security (Specialized Vendor)

Specialization: Generative AI (GenAI) and Large Language Model (LLM) Security

Why Lasso Security Today: Lasso Security specializes in securing Generative AI and Large Language Models (LLMs), making them directly relevant to the 'Promptware Kill Chain' threat which outlines attacks against AI models. Their platform is designed to detect and mitigate specific AI risks like prompt injections and jailbreaks, addressing the security challenges inherent in deploying or using LLMs.

Key Capability: Real-time detection and blocking of prompt injections, jailbreaks, and sensitive data leakage in LLM interactions.

Recommended Actions: 1. Navigate to Lasso Console → Policies → Firewall Policies → Create New Policy → Input Guardrails 2. Navigate to Lasso Console → Policies → Firewall Policies → Output Guardrails → Data Leakage Prevention 3. Navigate to Lasso Console → Shadow AI → Discovery → Inventory

Verification Steps: - Execute a benign 'Jailbreak' simulation (e.g., a 'Do Anything Now' prompt) against a protected LLM endpoint. - Navigate to Lasso Console → Observability → Alerts & Events

⚠️ Disclaimer: Test all detection logic in non-production environments before deployment.

1. Vendor Platform Configuration - Lasso Security

# Actionable Guidance for Lasso Security # Generated: 2026-02-16 16:24:12 # Step 1: Navigate to Lasso Console → Policies → Firewall Policies → Create New Policy → Input Guardrails # Purpose: Disrupt the 'Weaponization' and 'Delivery' phases of the Promptware Kill Chain by enabling real-time detection of prompt injections. # Expected: Activation of specific detectors for 'Prompt Injection', 'Jailbreaking' (e.g., DAN, virtualization), and 'Malicious Code' to intercept hostile inputs before they reach the LLM. # Step 2: Navigate to Lasso Console → Policies → Firewall Policies → Output Guardrails → Data Leakage Prevention # Purpose: Mitigate the 'Exploitation' phase by preventing the model from revealing sensitive data or executing successful exfiltration commands. # Expected: Configuration of 'PII Redaction' and 'Secrets Detection' rules that automatically sanitize or block model responses containing proprietary code, keys, or customer data. # Step 3: Navigate to Lasso Console → Shadow AI → Discovery → Inventory # Purpose: Address the 'Reconnaissance' phase by identifying unauthorized or 'Shadow' LLM applications currently in use within the environment. # Expected: A comprehensive list of unmanaged GenAI tools and browser extensions interacting with corporate data, allowing for immediate access revocation or policy enforcement. # Verification Steps: # - Execute a benign 'Jailbreak' simulation (e.g., a 'Do Anything Now' prompt) against a protected LLM endpoint. # Expected: The Lasso Firewall intercepts the request, returning a 'Blocked by Security Policy' response to the user, and the prompt does not reach the backend model. # - Navigate to Lasso Console → Observability → Alerts & Events # Expected: Verify that the simulated attack appears in the event log classified as 'High Severity' with the specific attack vector (e.g., 'Prompt Injection') correctly identified.
