This Metasploit modules exploits a critical vulnerability in Git Large File Storage (Git LFS), an open source Git extension for versioning large files, which allows attackers to achieve remote code execution if the Windows-using victim is tricked into cloning the attacker’s malicious repository using a vulnerable Git version control tool.

Why is kali so hated?

My best guess is because it’s the first thing everyone get instead of looking at the other options and skiddies think they are professional hacker after downloading it. Is this the reason or is there a different reason?

Apart from that I don’t understand why it’s so hated especially since it is a great distro for both experts and beginners alike.

DNSTake - A Fast Tool To Check Missing Hosted DNS Zones That Can Lead To Subdomain Takeover

A fast tool to check missing hosted DNS zones that can lead to subdomain takeover. What is a DNS takeover? DNS takeover vulnerabilities occur when a subdomain (subdomain.example.com) or domain has its authoritative nameserver set to a provider (e.g. AWS Route 53, Akamai, Microsoft Azure, etc.) but the hosted zone has been removed or deleted. Consequently, when making a request for DNS records the server responds with a SERVFAIL error. This allo ws an attacker to create the missing hosted zone on the service that was being used and thus control all DNS records for that (sub)domain.¹Installation from Binary The ez way! You can download a pre-built binary from releases page, just unpack and run! from Source NOTE: Go 1.16+ compiler should be installed & configured! Very quick & clean! ▶ go install github.com/pwnesia/dnstake/cmd/dnstake@latest — or Manual building executable from source code: ▶ git clone https://github.com/pwnesia/dnstake▶ cd dnstake/cmd/dnstake▶ go build .▶ (sudo) mv dnstake /usr/local/bin Usage $ dnstake -h ·▄▄▄▄ ▐ ▄ .▄▄ ·▄▄▄▄▄ ▄▄▄· ▄ •▄ ▄▄▄ . ██▪ ██ •█▌▐█▐█ ▀.•██ ▐█ ▀█ █▌▄▌▪▀▄.▀· ▐█· ▐█▌▐█▐▐▌▄▀▀▀█▄▐█.▪▄█▀▀█ ▐▀▀▄·▐▀▀▪▄ ██. ██ ██▐█▌▐█▄▪▐█▐█▌·▐█ ▪▐▌▐█.█▌▐█▄▄▌ ▀▀▀▀▀• ▀▀ ; █▪ ▀▀▀▀ ▀▀▀ ▀ ▀ ·▀ ▀ ▀▀▀ (c) pwnesia.org — v0.0.1Usage: stdin | dnstake options dnstake -t HOSTNAME optionsOptions: -t, --target Define single target host/list to check -c, --concurrent Set the concurrency level (default: 25) -s, --silent Suppress errors and/or clean output -h, --help Display its helpExamples: dnstake -t (sub.)domain.tld dnstake -t hosts.txt cat hosts.txt | dnstake subfinder -silent -d domain.tld | dnstake Workflow DNSTake use RetryableDNS client library to send DNS queries. Initial engagement using Google & Cloudflare DNS as the resolver, then check & fingerprinting the nameservers of target host — if there is one, it will resolving the target host again with its nameserver IPs as resolver, if it gets weird DNS status response (other than NOERROR/NXDOMAIN), then it's vulnerable to be taken over. More or less like this in form of a diagram. Currently supported DNS providers, see here.
