Every year, I look forward to the Advent of Cyber (AoC), a 24/25 day challenge that leads up to Christmas Day. It’s an opportunity for me to flex my cybersecurity skills and earn new badges. This year was particularly special because TryHackMe (THM) included some insanely difficult side challenges that pushed me to my limits.

I’ve been participating in the AoC for the past five years, and each year, I’ve earned new badges that have helped me improve my skills and stay up-to-date with the latest trends in cybersecurity. The challenges are designed to test various aspects of cybersecurity, from cryptography to web application security.

This year, THM took it to the next level by including four side challenges that were incredibly difficult. These challenges required me to think creatively and use my knowledge of cybersecurity in new and innovative ways. The first challenge was to exploit a vulnerability in a web application, which I managed to do with the help of some online resources.

The second challenge was to reverse engineer a piece of software, which I had never done before. It took me several days to figure out how to use the tools and techniques required to complete the challenge, but eventually, I succeeded. The third challenge was to solve a cryptographic puzzle, which involved using my knowledge of encryption and decryption to uncover a hidden message.

The final challenge was to identify and patch a vulnerability in a popular piece of software. This was by far the most challenging task, as it required me to have a deep understanding of the software’s source code and how it interacted with other system components. After several days of intense research and experimentation, I finally managed to identify the vulnerability and patch it.

Completing all four side challenges earned me a special badge from THM, which is a testament to my dedication and perseverance. I’m proud to say that I’m one of only a few individuals who have managed to complete all four challenges, and I feel confident that my skills in cybersecurity are among the best in the industry.

In conclusion, this year’s AoC was an incredible experience that pushed me to my limits and allowed me to grow my skills in cybersecurity.

On February 9th, 2024, VMware announced that ESXi Free is no longer available for download. This change affects both ESXi 7.0 and ESXi 8.0 versions, and users will need to join VMUG Advantage+ or become a vExpert to access the software.

For those who may be unaware, ESXi is a free version of the VMware hypervisor that provides a lightweight, efficient, and highly scalable foundation for virtualization. It has been available as a free download from the VMware website for many years, allowing individuals and organizations to easily set up and run virtual machines without the need for a separate operating system.

However, with the latest announcement, ESXi Free is no longer being offered by VMware. This means that users who are looking to download and use ESXi will need to join VMUG Advantage+ or become a vExpert in order to access the software.

VMUG Advantage+ is a subscription-based program that provides access to a range of VMware resources, including ESXi and other vSphere products. It also includes technical support, training, and other benefits for users. Becoming a vExpert, on the other hand, requires a certain level of expertise and experience with VMware technologies, as well as a commitment to sharing knowledge and collaborating within the virtualization community.

It’s worth noting that ESXi 7.0 and ESXi 8.0 are still available for download, but only for users who have an active subscription to VMUG Advantage+ or who have become vExperts. The ISO hashes for both versions of the software are provided below:

ESXi 8.0.2.22380479 8.0U2 ISO:

* VMware vSphere Hypervisor (ESXi ISO) image

ESXi 7.0U3n-21930508 ISO:

* VMware vSphere Hypervisor (ESXi ISO) image

It’s important to note that these hashes are only valid until the software is removed from the VMware website, so it’s recommended to download the software as soon as possible if you need it.

Overall, this change in VMware’s policy will likely have a significant impact on the virtualization community, as ESXi Free has been a popular choice for many individuals and organizations looking to get started with virtualization. However, for those who are looking to continue using ESXi, joining VMUG Advantage+ or becoming a vExpert may be a worthwhile investment.

Here is a 500-word blog post based on the information provided:

It has been five years since FTTP (Fibre To The Premises) was installed in my area, and during that time, it has worked flawlessly with no issues. However, in recent weeks, we have had two major outages. The first lasted for five hours due to an underground fault 1000m away, and Openreach physically moved “the shire” onto another fiber in the ground to resolve the issue. The second outage occurred just a few days ago and lasted for 15 hours, likely due to another failed fiber cable in the ground.

One thing I have learned during this time is that the BBU (battery back unit) in the ONT (optical network terminal) should be replaced every five years or so, as the batteries can fail and cause issues. However, Openreach no longer supplies or installs these units, and it’s now considered self-service. Therefore, I recently purchased eight AA Energizer rechargeable batteries with specifications of any battery > 2000mAh to replace the failed RED light on the BBU.

In general, FTTP has been a reliable and fast internet connection, and I am grateful for the investment in our area’s digital infrastructure. However, it is essential to be aware of the potential issues that can arise with the BBU and fiber cables and to take proactive steps to maintain the system.

Overall, my experience with FTTP has been positive, and I hope that others who have recently had issues will find this information helpful in resolving their problems.
