Cisco Fixed Critical ISE Flaws Allowing Root-Level Remote Code Execution

Cisco has released patches for multiple critical vulnerabilities in its Identity Services Engine (ISE), with CVSS scores as high as 10.0. These flaws allow unauthenticated remote attackers to execute commands with root privileges. The vulnerabilities arise from improper input validation and insufficient authentication in the web-based management interface. Cisco urges immediate patching, as no workarounds exist.

SOC Analysis: As a core component of identity and access management, ISE is mission-critical. Exploiting these flaws could allow attackers to take full control of networks. Organizations must prioritize patching and restrict access to management interfaces from untrusted networks. Incorporating ISE into vulnerability scanning and monitoring processes is essential to minimize exposure.

Critical Privilege Escalation Flaw in Notepad++ Leads to Full System Takeover

Notepad++ is affected by CVE-2025-49144, a vulnerability allowing arbitrary code execution via malicious files. This puts systems at risk, especially given the software’s widespread use among developers and IT personnel.

SOC Analysis: Even trusted tools like Notepad++ can be entry points for attackers. Organizations should apply updates, integrate these tools into security baselines, and educate users on handling files securely—particularly when received via email or messaging apps.

ClickFix Attacks Surge 517% in 2025

ClickFix, a growing social engineering technique, tricks users into copying and executing malicious code themselves by mimicking error resolution workflows. ESET reports it accounted for 8% of all blocked attacks in H1 2025.

SOC Analysis: ClickFix tactics exploit users’ desire to solve issues independently. These scripts are often run by users themselves, bypassing traditional detection systems. Training, verification workflows, and better awareness of “DIY tech support” scams are critical countermeasures.

Largest Data Breach Ever: 16 Billion Login Credentials Exposed

Researchers have discovered a data leak comprising 16 billion login credentials, collected through multiple info-stealing malware strains and compiled from 30 large-scale breaches. Many credentials are reused, presenting ongoing risk.

SOC Analysis: While some records are old, the volume makes password reuse a significant threat. Organizations should promote use of password managers, MFA, and regularly check exposures via services like Have I Been Pwned. Our SOC can also provide proactive leak monitoring services.

Warning: Fake Messages About De Watergroep

Phishing campaigns are impersonating De Watergroep, attempting to steal user data through realistic-looking emails. These often claim issues with meter readings or urge users to “update customer details” via fake portals.

SOC Analysis: While attackers increasingly use AI to create realistic phishing messages, simple steps like checking the sender domain and avoiding unexpected links remain powerful defenses. Suspicious messages should be forwarded to:

  • verdacht@safeonweb.be
  • suspect@safeonweb.be
  • suspicious@safeonweb.be

Our SOC is always available to assist with suspicious communication reviews.
