Tool Review: Tailsnitch, (Tue, Jan 6th)

Leave a comment
This post was originally published on this site

In yesterday's podcast, I mentioned "tailsnitch", a new tool to audit Tailscale configurations. Tailscale is an easy-to-use overlay to Wireguard. It is probably best compared to STUN servers in VoIP in that it allows devices behind NAT to connect directly to each other. Tailscale just helps negotiate the setup, and once the connection is established, data will flow directly between the connected devices. I personally use it to provide remote assistance to family members, and it has worked great for this purpose. Tailscale uses a "Freemium" model. For my use case, I do not need to pay, but if you have multiple users or a large number of devices, you may need to pay a monthly fee. There are also a few features that are only available to paid accounts.

Risks of OOB Access via IP KVM Devices, (Mon, Jan 5th)

Recently, a new "breed" of IP-based KVM devices has been released. In the past, IP-based KVM devices required dedicated "server-grade" hardware using IPMI. They often cost several $100 per server, and are only available for specific systems that support the respective add-on cards. These cards are usually used to provide "Lights Out" access to servers, allowing a complete reboot and interaction with the pre-boot environment via simple web-based tools. In some cases, these IPMI tools can also be used via various enterprise/data center management tools.

Happy New Year! I hope the holidays gave you time to recharge and spend time with your loved ones.

Like every year, I took a few weeks off after AWS re:Invent to rest and plan ahead. I used some of that downtime to plan the next cohort for Become a Solutions Architect (BeSA). BeSA is a free mentoring program that I, along with a few other Amazon Web Services (AWS) employees, volunteer to host as a way to help people excel in their cloud and AI careers. We’re kicking off a 6-week cohort on “Agentic AI on AWS” starting February 21, 2026. Visit the BeSA website to learn more.

There is still time to submit your idea for the Global 10,000 AIdeas Competition and compete for $250,000 in cash prizes, AWS credits, and recognition, including potential featured placement at AWS re:Invent 2026 and across AWS channels.

You will gain hands-on experience with next-generation AI development tools, connect with innovators globally, and access technical enablement through biweekly workshops, AWS User Groups, and AWS Builder Center resources.

The deadline is January 21, 2026, and no code is required yet. If you’re selected as a semifinalist, you’ll build your app then. Your finished app needs to use Kiro for at least part of development, stay within AWS Free Tier limits, and be completely original and not yet published.

If you haven’t yet caught up with all the new releases and announcements from AWS re:Invent 2025, check out our top announcements post or watch the keynotes, innovation talks, and breakout sessions on-demand.

Launches from the last few weeks
I’d like to highlight some launches that got my attention since our last Week in Review on December 15, 2025:

  • Amazon EC2 M8gn and M8gb instances – New M8gn and M8gb instances are powered by AWS Graviton4 processors to deliver up to 30% better compute performance than AWS Graviton3 processors. M8gn instances feature the latest 6th generation AWS Nitro Cards, and offer up to 600 Gbps network bandwidth, the highest network bandwidth among network-optimized EC2 instances. M8gb offer up to 150 Gbps of Amazon EBS bandwidth to provide higher EBS performance compared to same-sized equivalent Graviton4-based instances.
  • AWS Direct Connect supports resilience testing with AWS Fault Injection Service – You can now use AWS Fault Injection Service to test how your applications handle Direct Connect Border Gateway Protocol (BGP) failover in a controlled environment. For example, you can validate that traffic routes to redundant virtual interfaces when a primary virtual interface’s BGP session is disrupted and your applications continue to function as expected.
  • New AWS Security Hub controls in AWS Control Tower – AWS Control Tower now supports 176 additional Security Hub controls in the Control Catalog, covering use cases including security, cost, durability, and operations. With this launch, you can search, discover, enable, and manage these controls directly from AWS Control Tower to govern additional use cases across your multi-account environment.
  • AWS Transform supports network conversion for hybrid data center migrations – You can now use AWS Transform for VMware to automatically convert networks from hybrid data centers. This removes manual network mapping for environments running both VMware and other workloads. The service analyzes VLANs and IP ranges across all exported source networks and maps them to AWS constructs such as virtual private clouds (VPCs), subnets, and security groups.
  • NVIDIA Nemotron 3 Nano available on Amazon Bedrock – Amazon Bedrock now supports NVIDIA Nemotron 3 Nano 30B A3B model, NVIDIA’s latest breakthrough in efficient language modeling that delivers high reasoning performance, built-in tool calling support, and extended context processing with 256K token context window.
  • Amazon EC2 supports Availability Zone ID across its APIs – You can specify the Availability Zone ID (AZ ID) parameter directly in your Amazon EC2 APIs to guarantee consistent placement of resources. AZ IDs are consistent and static identifiers that represent the same physical location across all AWS accounts, helping you optimize resource placement. Prior to this launch, you had to use an AZ name while creating a resource, but these names could map to different physical locations. This mapping made it difficult to ensure resources were always co-located, especially when operating with multiple accounts.
  • Amazon ECS Managed Instances supports Amazon EC2 Spot Instances – Amazon ECS Managed Instances now supports Amazon EC2 Spot Instances, extending the range of capabilities available with AWS managed infrastructure. You can use spare EC2 capacity at up to 90% discount compared to On-Demand prices for fault-tolerant workloads in Amazon ECS Managed Instances.

See AWS What’s New for more launch news that I haven’t covered here. That’s all for this week. Check back next Monday for another Weekly Roundup!

Here’s to a fantastic start to 2026. Happy building!

Cryptocurrency Scam Emails and Web Pages As We Enter 2026, (Sun, Jan 4th)

This post was originally published on this site

Introduction

In October 2025, a work colleague documented a cryptocurrency scam using a fake chatbot. After investigating this, I was able to receive messages from the campaign, and these emails have continued to land in my honeypot account since then. This diary documents the cryptocurrency scam campaign as it continues in 2026.


Shown above: My honeypot email inbox with several emails from this cryptocurrency scam campaign.

Details

This campaign promises cash payouts on cryptocurrency that potential victims unknowingly have.

This campaign primarily abuses the minimalist publishing platform telegra[.]ph, which anyone can use to publish a simple web page very quickly. Many of these emails have minimal messaging and contain links to these telegra[.]ph pages.


Shown above: Example of an email from this campaign with link to a telegra[.]ph page.


Shown above: Example of a telegra[.]ph page from this campaign.

This campaign is not limited to abusing telegra[.]ph. Many of these emails contain Google Forms pages that lead to the telegra[.]ph page.


Shown above: Example of a Google Forms email from this campaign.


Shown above: Example of a response from the Google Forms link that leads to a telegra[.]ph page for this campaign.

These telegra[.]ph pages generally lead to the same type of cryptocurrency scam, stating you have over $100K in US dollars worth of Bitcoin from an automated Bitcoin mining cloud platform.


Shown above: Example of a page to begin the cryptocurrency scam.

In November 2025, I posted a video on YouTube, where I went through the website step-by-step, interacting with the fake chatbot to get to the actual scam. The scam involves paying a fee to convert the supposed Bitcoin to US dollars, which potential victims would send to a wallet controlled by the criminals.

Final Words

Many free services are easy to abuse for these types of campaigns. While these emails may seem obviously fake, they continue to be cost-effective for criminals to send, and criminals can easily abuse other services to host everything needed for this scam.

Debugging DNS response times with tshark, (Fri, Jan 2nd)

One of my holiday projects was to redo and optimize part of my home network. One of my homelab servers failed in November. I had only thrown the replacement in the rack to get going, but some cleanup was needed. In addition, a lot of other "layer 1" issues had to be fixed by re-crimping some network drops and doing general network hygiene. The dust buny kind hygiene, not so much the critical controls type. After all, I don't want things to overheat, and it is nice to see all network links syncing properly.
