Cybercriminals have found a way to hide their phishing pages in plain sight

Our cybersecurity stumbled across many phishing pages that are used by cybercriminals in millions of websites from cyberspace. At our last count from the previous month, more than 400 new phishing sites were hosted inside a folder named /.well-known/.

This folder is found in every site out there and is used as a Uniform Resource Identifier URI path prefix that allows users and automated processes to obtain policy and other information about the host and also to demonstrate ownership of a domain or to store SSL certificates from Automatic Certificate Management Environment ACME inside folders /.well-known/acme-challenge/ or /.well-known/pki-validation/. This folder is a perfect place for hiding phishing pages because is present in almost every ACME and Let’s Encrypt certified websites around the world, and their administrators ignore it or are unaware of its existence most of the time.

Because of the dot in front of the folder things are getting more complicated favoring the cybercriminals because any listing command of this folder hides any files stored in it, making more and more cybercriminals placing their scam sites inside folders like /acme-challenge/ and /pki-validation/ for better hiding.
Placing scam sites inside those folders is very easy for the cybercriminals because /.well-known/ directories are overly permissive allowing anyone and any website to put whatever content they want inside them for better collaboration between various platforms.

Our cybersecurity expert is worried about this threat and advises everyone to stay alert regarding various scam websites, saying that everybody should double check the address of a site and always use a security system like free antivirus or free firewall in every device connected to the internet.

Most of the companies don't care about cybersecurity until they suffer a breach.
A healthy company must perform a penetration test from time to time. The penetration test must execute against all the assets of the company, including the workers who are the most vulnerable to the social engineering attacks.
A penetration test can be done either by a security specialist from inside of the company or by hiring an external cyber security company who can take care of everything.
Besides penetration test, a company must have a minimum healthy cybersecurity system installed like antivirus or firewall.
