Signaling System No. 7 (SS7) is the protocol that carriers use to route calls and texts. In a real-world attack, an adversary with SS7 access can request the Home Location Register (HLR) of a phone, returning the subscriber's current cell tower (Lat/Long).
Can you do this for free on Kali? Not against real carriers. However, Kali includes Yate and OpenBTS modules for lab testing.
Sherlock finds usernames linked to a phone number (if the person used their number as a username recovery option).
sherlock --phone "+12345678900"
For learning purposes, practice PhoneInfoga in your own lab environment on numbers you own. Never use these techniques without authorization.

REPORT: Feasibility and Methodology of Geolocation via Phone Number on Kali Linux
Date: October 26, 2023 Subject: Analysis of "Find Location by Phone Number" Tools within Kali Linux Environment
| Tool Name | Purpose | Free? | |-----------|---------|-------| | Maltego | Graph-based OSINT (links numbers to social media, domains) | Yes (Community Edition) | | Sherlock | Username lookup (convert number to username patterns) | Yes | | theHarvester | Email/number scraping from search engines | Yes | | PhoneInfoga | Advanced phone number OSINT (carrier, country, line type) | Yes | | Recon-ng | Modular recon framework (has phone number modules) | Yes |
Kali Linux includes the Social Engineering Toolkit (SET). In theory, a penetration tester (with explicit authorization) could use SET to create a fake SMS message (smishing) that appears to come from a known source, tricking the target into clicking a link that captures their IP address—which can approximate a location (city level, not street). Signaling System No
Example (authorized test only):
sudo setoolkit
> 1) Social-Engineering Attacks
> 2) Website Attack Vectors
> 3) Credential Harvester + SMS spoofing
The result: If the target clicks the malicious link, you receive an IP address. Using geoiplookup <IP> in Kali:
geoiplookup 192.0.2.45
Output: GeoIP Country Edition: US, United States City: Chicago, Illinois
Warning: This is illegal without explicit consent. It violates CFAA (US), Computer Misuse Act (UK), and similar laws globally. Do not attempt on strangers. For learning purposes, practice PhoneInfoga in your own
So, can you find location by phone number using Kali Linux for free? In the sense of live GPS tracking—no. In the sense of discovering publicly linked cities, area codes, carriers, and social media footprints—yes, but only ethically and with limits.
Kali Linux is a powerful suite for authorized security testing. It transforms you into an investigator, not a stalker. The tools described (PhoneInfoga, Maltego, Sherlock, SET) must be used responsibly, with permission, and within the law.
Remember: True cybersecurity professionals help protect privacy, not invade it. Use your skills to secure systems, educate users, and harden defenses—not to track someone’s location without their consent.
