AVOID the malicious openew.app website

 

Based on current threat intelligence, I would treat openew.app as malicious and unsafe.

Several independent indicators point to it being a phishing/malware site:

• A recent security scan classified openew.app as a phishing site with a very low trust score and noted that 16 security engines flagged it. The domain was also only a few days old when analyzed, which is a common characteristic of malicious campaigns.
• Researchers at Malwarebytes reported that openew.app impersonates the official ChatGPT download page and delivers malware to both Windows and macOS users. According to their analysis, Windows users receive credential-stealing malware, while macOS users are served Atomic Stealer (AMOS), which targets passwords, browser data, and cryptocurrency wallets.
• Multiple malware sandbox analyses observed malicious behavior associated with downloads from the site and classified activity from the domain as malicious.

If you visited the site

• Simply viewing the page is generally lower risk than downloading and running software.
• If you downloaded and executed anything from the site, assume the computer may be compromised.
• If you entered any passwords, change them immediately from a known-clean device.
• Run a full antivirus scan and consider a second-opinion scanner such as Malwarebytes.
• Check browser-saved passwords, banking accounts, email accounts, and cryptocurrency wallets for suspicious activity.

DHCP Detective: Looking for Sparks Before it Becomes a Fire

If there’s one thing every network admin learns the hard way, it’s that DHCP problems rarely announce themselves politely. One minute everything is fine, and the next users are wandering the office asking why Wi-Fi suddenly stopped working. That’s why proactive DHCP troubleshooting matters. Instead of waiting for a full-blown outage, keeping an eye on your DHCP logs can reveal warning signs long before devices start losing addresses and chaos begins. In this example, I will refer to  Ubiquiti EdgeRouters, since I'm working with them quite a bit lately. One of the best places to start is the trusty command sudo cat /var/log/dhcpmasq.log

FYI.  the same methodology and tips will apply to any DHCP server.  

🚨 17 Million Devices. 200+ Servers. One Major Takedown.

Dutch authorities have successfully taken down a massive botnet that had compromised millions of devices — including computers, tablets, smartphones, and IoT devices — and was being used to carry out malicious cyberattacks. The Dutch Politie and the National Cyber Security Center (NCSC) confirmed that the network consisted of at least 17 million infected devices, with more than 200 servers based in the Netherlands serving as its backend infrastructure.

If network changes still involve enough copy-and-paste to make your Ctrl+C and Ctrl+V keys beg for mercy, this article is your official intervention. Network Automation Roadmap: The Ultimate Step-by-Step Guide lays out a practical path for taking your network from “mostly manual and mildly chaotic” to streamlined, automated, and actually manageable. It breaks down the automation journey into clear phases, making the whole process feel a lot less like decoding ancient router hieroglyphics and more like a plan you can actually execute. 

Why iPerf3 Should Be in Every Network Engineer’s Toolkit

There’s something deeply satisfying about proving your network is actually fast instead of just hoping it is. That’s where iPerf3 comes in. Setting up a simple performance test from a Windows 10 laptop to a Ubuntu 26 server gives you a real-world way to validate throughput, latency behavior, packet loss, and overall network stability. Better yet, throwing a Windows 11 VM into the mix inside that Ubuntu host adds another layer of realism that mirrors modern production environments where virtualization is everywhere.
