🚨 Cyber Alerts
1. Hackers Used React Native Flaw To Drop Rust Malware
A critical vulnerability in the React Native CLI Metro server is being actively exploited to execute remote commands and deploy stealthy Rust-based malware. Although the flaw allows unauthenticated attackers to run arbitrary code on exposed systems, it has remained under the radar with a low public risk score despite weeks of observed real-world attacks.
2. Hackers Compromise Nginx Servers For Redirects
A malicious campaign is currently targeting NGINX servers by injecting unauthorized configuration blocks to hijack and reroute legitimate user traffic.
3. Critical n8n Flaws Disclosed With Exploits
Critical security flaws in the n8n workflow automation tool allow authenticated users to escape the restricted environment and seize total control of the host server. These vulnerabilities, identified as CVE-2026-25049, enable remote code execution, giving attackers the ability to steal credentials and compromise connected cloud accounts.

💥 Cyber Incidents
4. Substack Data Breach Leaks User Contact Info
Substack, a popular platform for independent writers and experts, recently confirmed a data breach that exposed user email addresses, phone numbers, and internal metadata.
5. Hackers Breach 37 Countries In Espionage Campaign
A massive cyberespionage operation linked to an Asian state actor has successfully breached at least 70 organizations across 37 different countries over the past year. Security researchers have identified this as the most expansive government-backed hacking campaign since the 2020 SolarWinds attack.
6. Data Stolen After Ransomware Hit Texas Gas Chain
In September, a significant ransomware attack targeted Gulshan Management Services, resulting in a data breach that impacted 377,082 individuals. Although the company operates numerous gas stations and convenience stores, the exposure of Social Security numbers and driver’s license data suggests the breach likely affected employees rather than general retail customers.

7. Five Cybersecurity Bills Advance For Energy Sector
The House Subcommittee on Energy has moved forward with five bipartisan bills designed to strengthen the physical and digital defenses of the American electric grid and energy supply chains. These legislative efforts focus on updating Department of Energy programs to better protect rural utilities, pipelines, and community infrastructure against the growing risk of sophisticated cyberattacks.
8. Denmark Recruits Hackers For Cyber Ops
Denmark’s military intelligence service is actively recruiting cybersecurity specialists to conduct offensive operations aimed at compromising adversary networks. These recruits will undergo a five-month training program at a specialized hacker academy to bolster national security through proactive digital measures.
9. Man Pleads Guilty To Hacking 600 Accounts
Kyle Svara, a 26-year-old from Illinois, pleaded guilty in federal court to hacking nearly 600 Snapchat accounts to steal and distribute private nude photos. His victims included students at various colleges and women targeted at the request of a former university track coach who was previously convicted of sextortion.

📈Cyber Stocks
On Friday, 6 February 2026, major cybersecurity equities trended lower alongside broader technology pressure, though underlying demand narratives for enterprise, cloud, and identity security persisted.
Okta Inc closed at 82.15 dollars and declined, with identity and access management stocks reflecting broader tech caution.
Zscaler Inc ended near 169.39 dollars and was lower, as cloud-centric zero-trust security equities lagged amid profit taking.
Fortinet Inc finished around 78.93 dollars and moved down, despite recent strong earnings results that highlighted billings growth.
Check Point Software Technologies Ltd. closed near 176.25 dollars and was modestly lower, with defensive security demand steady but not immune to sector weakness.
SentinelOne Inc ended at 12.93 dollars and declined, as smaller AI-enabled endpoint security names saw risk-off flows.
💡 Cyber Tip
⚠️ Hackers Exploit React Native Flaw to Drop Rust Malware
Attackers are actively abusing a flaw in the React Native CLI Metro server to run remote commands and deploy stealthy Rust-based malware. The vulnerable dev server binds to external interfaces by default, allowing unauthenticated command execution and making exposed developer machines an easy target.
🛠️ What You Should Do
Do not expose Metro servers to the internet or untrusted networks
Bind the Metro server to localhost only
Block access to development ports using firewall rules
Monitor for unusual PowerShell activity on developer systems
Keep React Native tooling updated and review default configurations
⚠️ Why This Matters
Developer environments are high-value targets. A single exposed dev server can lead to malware deployment, credential theft, and supply chain compromise long before the issue gains widespread attention.
