Making a microcontroller perform as a frequency counter is a relatively straightforward task involving the measurement of the time period during which a number of pulses are counted. The maximum …read more Continue reading NTP, Rust, and Arduino Make a Phenomenal Frequency Counter
Most Hackaday readers will be familiar with the idea of a network time server; a magical box nestled away in some distant data center that runs the Network Time Protocol …read more Continue reading Portable GPS Time Server Powered by the ESP8266
LEDs have become so ubiquitous in our projects that just hearing that term probably conjures images of tiny illuminated domes in an array of single-spectrum colors. It’s easy to forget …read more Continue reading A Custom Clock with LED Filament Hands
We’re always fans of interesting clock builds around here, whether it’s a word clock, marble clock, or in this case a clock using a unique display method. Of course, since …read more Continue reading Using Heaters to Display Time
I recently tested the NTP Time Synchronization Attack as desribed and demonstrated by Jose Selvi in 2015.
Basically, the attack was mostly used to send the victim’s clock in the future, so the already cached HTTP Strict Transport Security … Continue reading How did ntpd got pacthed to prevent NTP time synchronization attacks?
Building a clock of some sorts seems to be a time honored tradition for hackers and LED clocks seem one of the most popular. You can build anything from a seven-segment display to a binary clock or something even more …read more
If binary digits are bits, are quinary digits “quits”? Perhaps, but whatever you call them, you’re going to have to wrap your head around some new concepts in order to make sense of this quinary display clock.
Why quinary? [Spike Snell] wanted to minimize the number of LEDs, and 5 …read more

Nessus scan reported NTP mode 6 Scanner, these are some switches/routers and Linux systems. The description says that these systems can be utilised is an amplification based Ddos attacks.
None of these servers is exposed to the internet an… Continue reading NTP Mode 6 Scanner should be remediated on an internal network?
For many people, these last few weeks have been quite an adjustment. When the normal routine of work or school is suddenly removed, it’s not unusual for your internal clock to get knocked out of alignment. It might have started with struggling to figure out if it was time for …read more

The elegance of Power over Ethernet (PoE) is that you can provide network connectivity and power over a single cable. Unfortunately not nearly enough hardware seems to support this capability, forcing intrepid hackers to take matters into their own hands. The latest in this line of single-cable creations is this …read more
