Let's start with IP addresses. 📡
An IP (Internet Protocol) address is a unique numerical identifier assigned to devices on a network. It's like a phone number for your device on the internet. #NetworkingBasics

#Domains are #namespaces that are used for coupling #IP-addresses to human-readable names for ease of use.
They are also organized in a hierarchical structure for governance purposes.

❓What is a Name Collision ❓
In #Web2 a collision occurs when an attempt to resolve a #domain name in a private namespace results in a query to the public #DNS
When private and public domain namespaces overlap, it can create security risks, confusion, and systems failure.

While traditional #Web2 domain names are organized by @ICANN , there is no such governing body or alliance in #Web3.
In Web3, “domains” are used to send and receive #cryptocurrency in place of lengthy alphanumeric wallet addresses and are a vital component of Digital #Identity

TECH Thread 🧵 DNS Root Zone & Alt Roots
❓What is a #DNS Root Zone❓
The “Root Zone” is the highest level of the Domain Name System structure. It contains the names and the numeric IP addresses for all top level #domain names such as .com, .net & .org

❓How does the Root Zone work❓
Every time you try to connect to a website or any other online service, and enter a web address your their browser, this action triggers a DNS lookup, and all DNS lookups start at the root zone.
Every time you try to connect to a website or any other online service, and enter a web address your their browser, this action triggers a DNS lookup, and all DNS lookups start at the root zone.
Once the lookup hits the root zone, the lookup will then travel down the hierarchy of the #DNS system, first hitting the TLDs servers, then the servers for specific domains (and possibly #subdomains)

Hardly anyone has heard of Sophia Yuferev - a disabled woman, whose body was found in her flat months after all her benefits had been removed.
She'd been hounded for years by the DWP, & repeatedly failed by other public bodies.

Sophia was a talented artist who lived with significant mental distress, & had been living on a sandwich a day for the last few months of her life after both her employment & support allowance (ESA) & her personal independence payment (PIP) had been stopped.
Her body was discovered by police in her flat in Hornchurch, Essex, in November last year, weeks after she had died.
Her electricity had been cut off months earlier for non-payment of bills.

1a. - DNS
To really understand #ensdomain you first need to know their web2 counterpart: #dns, which means "domain name system". We take for granted what it does for us because we don't have to remember numbers like "142.250.188.238" in order to get to google.com.

But, without DNS, we would have to (sort of; there were other protocols developed as solutions before DNS, but DNS is what we have been using since 1983. The previous solutions were not very efficient, but I won't go into a tangent about them).

DNS stands for Domain Name System.
DNS is the system that translates domain names into IP addresses, allowing your network to find the correct website and your browser to load it. Here is a breakdown of the five DNS steps involved in loading a webpage. 👇🏼

1️⃣ DNS Cache
When you search for a website, it will be stored on your system's DNS cache and retrieved from there if you have visited it before.
If cached, the rest of the DNS search ends here.

En primer lugar, un inciso:
Cache DNS de tu ISP o proveedor DNS ➡️ Cache DNS de tu Router ➡️ Cache DNS de Windows ➡️ Cache DNS del navegador
¿A que mola el chorro de lugares donde puede almacenarse un registro DNS? ¿Vas pillando ahora el tema no? ¡Pues seguimos!

De todo ese chorro de cachés puedes controlar fácil la del router simplemente accediendo y borrándola (en Mikrotik por ejemplo IP->DNS->Cache->Flush Cache) o bien a lo bestia reiniciando el cacharro y punto...

In light of the recent #SupplyChain attack on @KaseyaCorp by #REvil, it is worth paying attention to decoder[.]re included within the ransom notes, used additionally to 'mirror' in TOR network. #Ransomware #Cybersecurity #ThreatIntel #ThreatHunting #Malware
Similar to decryptor[.]cc and decryptor[.]top in previous #REvil/#Sodinokibi versions, decoder[.]re is used to grant the victims access to the threat actors WEB-site for further negotiations should their connection be limited via #TOR.
To access the page in WWW or TOR - the victim needs to provide a valid UID (e.g. "9343467A488841AC")
