hacking: security in practice
Curious as to how I was compromised.
Background info I try take my cybersecurity pretty strict. Just finished sec+, have complex password, 2 FA + authentication app.
Woke up to my Instagram being hacked. What I thought was very very suspicious was the attacker, had created an new gmail with my first + middle + last name. The last name was misspelled. However…. I do not advertise my middle name anywhere. Additionally, my insta account is my first initial and not my complete last name. Example if my name is John Doe I had my insta set up as J.Do. Whoever hacked my Instagram account knew my complete name? They also went as far as to create a new gmail address using my name? I had received no notifications that my original email on my insta account had be changed or that 2 FA was turned off. Additionally my username was changed. The hacker had complete access to my account for 6 hours and all they did was unfollowed one person. I am very curious as to how this is possible, I am a bit embarrassed as I am wanting to work in the cybersecurity field. Would love anyones thoughts.

A Detailed Guide on Responder (LLMNR Poisoning)
IntroductionResponder is a widely used tool in penetration test scenarios and can be used for lateral movement across the network by red teamers. The tool contains many useful features like LLMNR, NT-NS and MDNS poisoning. It is used in practical scenarios for objectives like hash capture or poisoned answer forwarding supporting various AD attacks. The tool contains various built-in servers like HTTP, SMB, LDAP, DCE-RPC Auth server etc. In this article, we will cover a majority of these attacks that can be performed while being aided by responder.Table of content· LLMNR, NBT-NS, MDNS and DHCP· Responder Installation· Attack 1: LLMNR/NBT-NS Poisoning through SMB· Attack 2: LLMNR/NBT-NS Poisoning through WPAD· Responder Analyze Mode· Responder Basic Authentication Mode· Responder Downgrade NTLMv2-SSP to NTLMv2· Responder external IP poisoning· Responder Multi-Relay: Shell on a system· Responder DNS injection in DHCP response· What are these servers in responder?· Recommendations· ConclusionLLMNR is a protocol which allows name resolution without the requirement of a DNS server. It is able to provide a hostname-to-IP based off a multicast packet sent across the network asking all listening Network-Interfaces to reply if they are authoritatively known as the hostname in the query. It does this by sending a network packet to port UDP 5355 to the multicast network address. It allows IPv4 and IPv6 hosts and supports all current and future DNS formats, types, and classes. It is the successor of NBT-NS.NBT-NS: NetBIOS name service (NBT-NS) is a Windows protocol which is used to translate NetBIOS names to IP addresses on a local network. It is analogous to what DNS does on internet. Each machine is assigned a NetBIOS name by the NBT-NS service. Works on UDP port 137. It is the predecessor of LLMNR.MDNS: Multicast DNS (mDNS) is a protocol aimed at helping with name resolution in networks. It doesn’t query a name server, rather, multicasts the queries to all the clients in a network directly. In multicast, an individual message is aimed directly at a group of recipients. When a connection between sender and recipient is made, all participants are informed of the connection between the name and IP address, and can make a corresponding entry in their mDNS cache.LLMNR/NBT-NS Poisoning: Let’s say a victim wants to connect to a shared drive \\wow so it sends the request to the DNS server. The only problem is that DNS can’t connect to \\wowas it doesn’t exist. Therefore, server replies back saying he it can’t connect the victim to \\wow. Thereafter, the victim will multicast this request to the entire network (using LLMNR) in case any particular user knows the route to the shared drive (\\wow).DHCP Poisoning: Dynamic Host Client Protocol (DHCP) is used to provide a host with its IP address, subnet mask, gateway etc. Windows uses multiple custom DHCP options like NetBIOS, WPAD etc. By poisoning th[...]

However, when the provided share name doesn’t exist, the system sends out an LLMNR query to the entire network. This way, if any user(IP address) has access to that share, it can reply and provide the communication to the requestor.responder -I eth0https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj8rSxYx0GVfXz6W5907NN5x_n1AOhAICepo6t5OubuU9xpih2Zo9s9m2kF2eq8vBOJOUD2VKEqASl9ZbGJTm84Cvke2lxZTpDrUc-zkf1Exs4QLiSHQQcM_7I1vEFeMbJAUr4g4OQrlo7rtdB49gv-ZUAs9hNaEjFFX9AOntC2TSCI3v0p6jL-ycw75g/s16000/3.png Now, when the victim tries to access shared drive “wow” he sees this!

WPAD by default uses DHCP to locate a cache service to facilitate straightforward connectivity and name resolution.Attack: To configure WPAD rogue proxy server we use the -w option. Furthermore, we added an optional switch of DHCP injection. This switch would inject rogue proxy’s address (kali IP) in the DHCP response. The attack could still work without this switch.responder -I eth0 -wdhttps://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjnV2okcE5GQHOMfODfMVdW26OkUKM1GDK2gb2Fy4qh1TyCiTnccmAJC4x9UuUP5evlPyqGHnyCvAuXiXU9RF_Nspd-1BmEloS5M9oNtGfY1mqSpRg9IZUxF3IKNdVNp2JswIazgWFo3GLhVRYi5DEWz3em8zc0_WEOBMy80IfwF6WhDxFA7z9cLXnlsg/s16000/9.png As you can see above, that DHCP poisoner and WPAD proxy have now been turned on. Now, when a user inputs any wrong URL, lets say, randomurl.local, browser couldn’t locate it. Responder poisons and injects DHCP response with WPAD’s IP and the browser tries to authenticate to the WPAD server and gives a login prompt.hashcat -m 5600 HTTP-NTLMv2-fe80::ddc5:3b8f:e421:a88a.txt /usr/share/wordlists/rockyou.txthttps://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhSeuUPL41x8-4E_puFlUlyoYeCOrt3EIa7F_U0EtrO-_AS-nX9CengCfGrqTJEBIl0sVjUXwHQDE8KZj6_HqQd1km0DjiSqq3vo-yx[...]

In turn, we were able to retrieve the NTLMv2 hashes. We will imitate the same attack but this time, try to gain clear text credentials of the user using basic authentication! This can be achieved using the -b flag. Further, we are using -F switch to force basic authentication!responder -I eth0 -wdF -bhttps://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiOpPK0XcbbInB5BoRS8VhcgsvIaFW4Kk4tlRo3V-7I87WH04pztzwZ-7kStR2uvijvqay7Bbaf7_R7IFnkiYulx1jYorRaTbaNidLf7wUYCXdDLEScfNVKs5xRE6lhDapkBetYXxajfy8sz7Ir5Bt1CWRQjqRSOTF5v9FBqMGOHw2IGRG5uh_vDKvu2A/s16000/17.png Now, when a user tries to access any invalid URL, he sees the following prompt with the message saying that these credentials would be sent in clear text using basic authentication.Responder Downgrade NTLMv2-SSP to NTLMv2NTLM provides ESS functionality (Extended Session Security) which adds to the complexity of the NTLM hash. ESS functionality adds an “SSP” flag in the NTLM hash (NTLM2-SSP). This increases the length of our NTLM hash in turn increasing complexity to crack the hash. We can configure Responder to use simple NTLMv2 (without ESS) which would result in lower time complexity to crack hashes.responder -I eth0 -wdF --lm --disable-esshttps://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEglJ1KdgpOp_SetRFRiiZD0ia-5kjaDV870C8HA0QjOWFlAAsc4Lhf3-LCgchtZTKdjvJVT-pNHJQcL6G5slsM5MyohwZLnDN3SNvoSVSYA7K0eqMoV-_pZ-C29aPCtf4sat6VolBjnVOWdgSEF8uOp1Dje886FvCYIcm[...]

A relay or forwarder receives valid authentication and then forwards that request to another server/system and tries to authenticate to that server/system by using the valid credentials so received. In Attack 1, we used an invalid SMB share to get hashes of the requesting system.apt-get install gcc-mingw-w64-x86-64 -o get-pip.pyOnce its done, we can run MultiRelay.py without any errors or warnings.cd /usr/share/responder/toolshttps://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiclVu9C20yW4shf3dcR6kX2OeHEPwrJKYA2MlLFh8Keuo809U7gvLRHx9gPUbh-kTOPsd0fTZKEQvYgEiSEFZI9UKX1ACjrAL3P-ayg2l1kOgzgH4E_m6skzGh7oKra4i8ITjcZvfk6S5iUe8yRu0iP0jniDfWYEeuaiFV3DzhyK4s15jmKe5X5MD5vg/s16000/25.png Now, first criteria for this attack to work with SMB is that SMB signing has to be disabled.

n see, SMB signing is disabled so the coast is cleared. We can run MultiRelay now. To run it we need to specify the target using “-t” and “-u” specifies users to which relay is to be forwarded.

One other thing to note here is that this script is using HTTP and SMB ports. So, to prevent any conflict, we need to turn these servers OFF in responder.conf file. We just open the file in /usr/share/responder/Responder.conf and turn off HTTP and SMB. If done properly, when we launch responder next time, an OFF switch like this shall be there.responder -I eth0https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiQ94WfyBjVthLSbN5RPjcE9ey4fOg7AgbUfyHkTs-vZXUGEexUGpLex01jw-kMuF69RUZJ4of-COrrzpNc8RApKEr-G4Q5ZITwLAljee8TfAQV8Xy-MHSNrdMwYTNPbxo-WBXXVFoTqhaRINvTBHJLt4wSbtXcsFreljTJM-5XTJq0UzFOMguVr54FLg/s16000/28.png Now, an administrator tries to open a shared drive. He is unsuccessful as the share wowowow doesn’t exist! So, responder intervenes and poisons requests successfully.Responder DNS injection in DHCP responseIn the event where DHCP is being used to identify the IP which is hosting, let’s say, an SMB drive called “wow” (refer attack 1), responder can also inject a rogue DNS record in DHCP responses. responder -I eth0 -Dhttps://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhGAi6-2EZiRxVZD0edpvgVSGMFzKjrn8fkYNTBTf7XNcEL4-PyiUAMCnhl3tpO6AK4X5MdEn_Kg0ZkDXH1XKlOSai0O4KWdFUCfCmwf5-yQd3lDH9PeeYPrrmP6C64hWtSObcaAYBJgTYfKtyTOeGHxIPigaxXKbYKGD3C-MusyOYUMU1Ty1ukQhtMmg/s16000/32.png When the victim accesses any invalid share, a prompt is now visible.___________________________

Often in pentest scenarios, to conduct lateral movement, we need to compromise credentials. Sending in malicious attachments with links to our rogue servers may fool a user into authenticating and hence, give us his credentials. Alternately, we can us relaying (Impacket’s toolkit) to conduct various other attacks. For example, in this article, we have conducted LDAP relaying using impacket’s ntlmrelay script and poisoning using responder in order to take over workstations.RecommendationsTo prevent attacks demonstrated above, following are recommended:computer configuration->admin templates->networkConclusionThe article covered various useful attacks which can be performed with the help of Responder. The tools is coded in Python and hence, is platform independent. Red teamers heavily use this tool to conduct lateral movement. The aim of the article is to serve as a ready reference when it comes to using responder in pentest scenarios. Hope you liked the article. Thanks for reading.___________________________

Was my macbook hacked via video chat ?
Last night I was bored and decided to hop on Chatroulette.com! I met two girls who I thought were cool. They asked me a question about what computer I was using, told them it was a 2019 MacBook, they asked for the OS version, I told them it was Big Sur – that was all I told them. I asked if they were students they said they were professionals in computer science & that my computer had just been hacked & dropped off the call. I immediately turned off my internet & shutdown. After a while I turned it back on and I didn’t notice anything weird on my computer. No sign that I was hacked at all. I’m updating to Monterey right now & have signed out of iCloud. Ps: I didn’t click any link whatsoever.
Was I truly hacked? What can I do? 🚧

Exposing fake websites
So on 08/04/2022 I bought an expensive community item from steam (cs:go), and like after 2 - 3 hours i was getting a lot of friend request on steam. I accepted 2 of them (i knew it was sketchy) so then the person on the other side asked me to play a tournament for them, I said okay what time and what place, the person responded with the time and location then after he asked me to vote for his team on a particular website and he sent me the link on steam chat, I opened the website, the website is designed beautifully like any modern website, so I stared my investigation further, there was a login button i clicked it it made a popup asking for steam sign in, luckily i carry around a fake steam I'd with me that has no games in it except CSGO so as i proceeded to login i got a error code 503 ( the site you are trying to reach is offline) so this further raised my sus. Now the intresting part is the pop up which opened for me to log into steam was made with pure Java script to make it look like a real one, it would't just come outside the Bowser window(pretty creative,) hell the site even uses cloudflare and has https in the link. Now I just want them to suffer so suggest me how do I do that, or if you to want to join me welcome aboard, these people are menace to the society so i would like to destroy their work, so please suggest me how to do that, what should I start with (also if you need the website do DM me )

Books on the physical side of hacking
Hey r/hacking, there's a lot of good books on the IT side of hacking, but i haven't seen a lot of people recommending books on non destructive entry, bypassing, access control, lockpicking, etc.
Does anyone know good books or general resources on this? Thanks

Reverse VPN server?
Raspberry pi is connected to public/wifi/internet. How would be possible to raspberry pi connects to a remote server (like linode or even a PC) and rpi is used as a vpn server, like reverse shell, no port forwarding?
Possible solutions:
1.
Rpi connects to a vpn server, pc through vpn ssh into rpi and port forward vpn server through ssh tunnel. Problem: Rpi is a vpn server and connects to a vpn (is that possible)
2.
Rpi on boot ssh into server, port forward vpn server through ssh tunnel. Problem: port forward from client to server (is that possible)
