Wireless Network Penetration

How WiFi Networks Get Cracked in Real Labs (WPA/WPA2 Attack Demo) 🔓 Most people think their WiFi is 100% secure just because it’s WPA2 protected. But in the world of cybersecurity, we know: ➡️ Encryption ≠ Invisibility Here's how ethical hackers and red teamers simulate real-world wireless attacks to expose weak configurations 🔍👇 ⚔️ Tactic Used: Man-in-the-middle (MITM) phishing-based authentication bypass 🧪 Environment: Kali Linux + Fluxion T-o-o-l 🎯 Target: WPA/WPA2 protected network (Test Lab Only!) 📶 Mode: Evil Twin Access Point Setup 🧠 Step-by-step (for Educational Purpose): 🔎 Scan WiFi Networks → Identify the target SSID & channel using built-in scanning tools. 📡 Clone the Network → Create a fake AP using Fluxion T-o-o-l that looks exactly like the real one. 🚫 Deauthenticate Users → Kick real users off the network using deauth packets (in test lab only). 🎭 Phishing Portal Triggered → When users reconnect, they’re redirected to a fake login portal. 🔐 Capture Password → Once user enters WiFi password, it’s captured and verified live using handshake file. 💥 Access Gained (Demo Only) → If correct, attacker gains access; in real-world, this exposes weak human behavior — not encryption flaws. 🛡️ Why This Matters: ✔️ Helps organizations train employees to spot fake login pages ✔️ Promotes awareness about Evil Twin attacks ✔️ Encourages use of 2FA + Strong Passwords + MAC Filtering ⚠️ Disclaimer: This is purely for educational and awareness purposes. Never perform such simulations outside of authorized environments.

The risk of insecure WiFi has just increased, with the revelation of the Nearest Neighbor attack, used in 2022 by the Russian GRU. Attacking WiFi is usually assumed to require close access - “war driving” to discover networks, and then connecting from an antenna close to the target. According to cyber security firm Volexity, in early 2022, attackers from Russian military intelligence agency GRU (aka APT28, aka Fancy Bear) were able to compromise a Washington DC-based office across the street from their target, then use WiFi from the compromised WiFi network to attack the target network. This method of attack reduces operational risk, as it can be carried out from abroad rather than risking a “Mission Impossible” team on the ground. We can probably assume this style of attack is already in use elsewhere. As with most cybersecurity, the basics apply here: 🔵 Upgrade to a strong WiFi security protocol such as WPA3-Enterprise 🔵 Apply MAC address filtering to only allow known NICs to connect to your WiFi 🔵 Use separate WiFi networks for IOT devices (anyone remember the casino that got hacked using the fish tank thermometer?) 🔵 Segment your networks to prevent lateral movement (see NIST SP 800-207 for advice on how to do this well, aka “Zero Trust”) 🔵 Consider using Ethernet and avoid WiFi altogether! It’s faster and more reliable…

In 2018, Dutch police red-handedly caught foreign spies who hacked into UN chemical weapons organization. Their attack method: Parking vehicles outside of target buildings, and infiltrating target's Wi-Fi networks to hack victims!   They were caught in person due to their physical presence near the target. As per a recent report (from Volexity), attackers now developed a new technique to overcome this risk: By "remotely" breaching the target's Wi-Fi by hijacking a laptop in a nearby building across the street! How is that even possible? Read on to learn more…   𝗔𝘁𝘁𝗮𝗰𝗸 𝗙𝗹𝗼𝘄: 1) The attacker uses password-spraying attack on target company's public-facing service > Gains credentials > But MFA blocks access.   2) The same credentials can access target enterprise's Wi-Fi (which does not have MFA) > But the challenge: the attacker is thousands of miles away from the target and cannot authenticate to Wi-Fi. 3) Here comes the genius: To overcome this, attacker starts looking for organizations located in target's nearby buildings (to use them as a bridge to connect to target's Wi-Fi)   4) Over months, attacker compromises nearby organizations, using their networks to get closer!   5) In the compromised orgs, attacker locates dual-home devices e.g., laptops with both wired and wireless connections near the target’s Wi-Fi range.   6) Using a dual-home device, they connect to target's Wi-Fi access points (remember they already have valid creds from step 1).   7) Once on target Wi-Fi, attacker uses RDP from an unprivileged account > Moves laterally, find valuable data > Exfiltrates it using built-in Windows tools to avoid detection.   𝗔 𝗙𝗲𝘄 𝗧𝗵𝗼𝘂𝗴𝗵𝘁𝘀: 1) Modern attackers are problem solvers first, hackers second. They can turn almost an impossible sounding event into possible.   2) When MFA blocks the front door, attackers will simply find a door without MFA. In this case, "corporate Wi-Fi" was that unlocked door. Threat model to identify similar unlocked doors in your company. 3) Corporate Wi-Fi networks are often overlooked in security assessments. Use certificates to authenticate devices or users (instead of passwords that can leak). This way, only devices with valid certificates can connect.   4) Segment and isolate networks. Create separate VLANs for different purposes - ex: Corporate vs Guest vs IoT.   5) Monitor Wi-Fi signal strength at your company's physical perimeter to reduce exposure of access points outside your premises. 6) Adopt WPA3-Enterprise encryption for enhanced security.

Hackers Breach U.S. Firm Over Wi-Fi—From Thousands of Miles Away 🚨 In a groundbreaking attack, Russian state hackers APT28 (Fancy Bear) bypassed physical proximity to breach a U.S. firm’s Wi-Fi network—directly from Russia. Using a creative “Nearest Neighbor Attack,” they exposed critical vulnerabilities in corporate Wi-Fi security. → What Happened? APT28 compromised a nearby organization via password-spraying attacks, then exploited dual-home devices to leap onto the target’s Wi-Fi network. By bypassing MFA and exploiting a zero-day vulnerability in Windows Print Spooler (CVE-2022-38028), they infiltrated systems, exfiltrated sensitive data, and escalated privileges—all remotely. → Why This Attack is Groundbreaking: ↳ Hackers no longer need to be physically close, like in a parking lot. ↳ This “Nearest Neighbor Attack” uses nearby networks as a gateway to victims. ↳ Detected by Volexity, it highlights the hidden dangers of unsecured corporate Wi-Fi. → Lessons for Securing Your Corporate Wi-Fi: ➜ Implement Network Segmentation ↳ Isolate Wi-Fi from critical systems to limit hacker movement. ➜ Strengthen Authentication ↳ Use enterprise-grade encryption and authentication protocols. ➜  Monitor Device Behavior ↳ Track connections and flag unusual patterns. ➜ Update Systems Regularly ↳ Patch vulnerabilities like Print Spooler to close potential entry points. ➜ Secure Dual-Home Devices ↳ Protect devices that bridge wired and wireless networks. APT28’s attack proves hackers no longer need physical proximity to infiltrate corporate systems. Act now to fortify your Wi-Fi security before it’s too late. PS: How secure is your Wi-Fi network?

𝐖𝐢-𝐅𝐢 𝐇𝐚𝐜𝐤𝐢𝐧𝐠 𝐰𝐢𝐭𝐡 𝐭𝐡𝐞 𝐁𝐞𝐚𝐬𝐭: 𝐀𝐥𝐟𝐚 𝐀𝐂1900 💀📡 Today I was testing a Wi-Fi network near my neighborhood — specifically my friend’s router, around 150 meters away. Surprisingly, I was able to compromise it using a classic technique: the Pixie Dust Attack. 📡🧪 Even though the router was using WPA2 security, the real issue was the WPS (Wi-Fi Protected Setup) being enabled. Many older routers still: ✅Have WPS PIN mode enabled ✅Use weak E-S1/E-S2 values ✅Lack rate limiting or lockouts after failed attempts This makes them extremely vulnerable to attacks like Pixie Dust. 🔐 𝐁𝐞𝐬𝐭 𝐒𝐨𝐥𝐮𝐭𝐢𝐨𝐧? 𝐔𝐩𝐠𝐫𝐚𝐝𝐞 𝐭𝐨 𝐖𝐏𝐀3. WPA3 uses 𝐒𝐀𝐄 (𝐒𝐢𝐦𝐮𝐥𝐭𝐚𝐧𝐞𝐨𝐮𝐬 𝐀𝐮𝐭𝐡𝐞𝐧𝐭𝐢𝐜𝐚𝐭𝐢𝐨𝐧 𝐨𝐟 𝐄𝐪𝐮𝐚𝐥𝐬) and newer encryption methods like ECDH and ECC to significantly strengthen key exchange and block these kinds of attacks. 🛑 𝐃𝐢𝐬𝐜𝐥𝐚𝐢𝐦𝐞𝐫: This test was done with full authorization on my friend’s network.

'Blizzard/Sofacy) breached a U.S. company through its enterprise WiFi network while being thousands of miles away, by leveraging a novel technique called "nearest neighbor attack." The threat actor pivoted to the target after first compromising an organization in a nearby building within the WiFi range. The attack was discovered on February 4, 2022, when cybersecurity company Volexity detected a server compromise at a customer site in Washington, DC that was doing Ukrainian-related work. APT28 is part of Russia's military unit 26165 in the General Staff Main Intelligence Directorate (GRU) and has been conducting cyber operations since at least 2004. The hackers, which Volexity tracks as GruesomeLarch, first obtained the credentials to the target's enterprise WiFi network through password-spraying attacks targeting a victim's public-facing service. However, the presence of multi-factor authentication (MFA) protection prevented the use of the credentials over the public web. Although connecting through the enterprise WiFi did not require MFA, being "thousands of miles away and an ocean apart from the victim" was a problem. So the hackers became creative and started looking at organizations in buildings nearby that could serve as a pivot to the target wireless network.' https://lnkd.in/gbDMQaji
