3/ Fuzzy Malicous URLs:
Observations:
🔎 Many common phishing campaigns tend to use URLs similar to the official sites
Example: Openssea[.]com vs. Opensea[.]io
4/ Homoglyphs:
Observations:
🔎 Recently we’ve noticed an increase in the usage of Homoglyphs ← Characters that look like each other
For example: PREMłNT[.]XYZ vs PREMINT[.]XYZ
When resolving such domains you get punycode ← converts words that cant be written in ASCII
5/ Punycode:
Observations:
🔎 Say you’re resolving the domain: Openséa[.]app ← This is what the omnibar (search bar on your browser) will say the domain is.
🔎 However, when resolved the way your browser interprets it, the URL looks very different: xn — opensa-fva[.]app

6/ Key Takeaways:
◼️ Links are not always as they seem
