Soluții pentru problemele tale IT
While Linux isn’t strictly a text-only system, it has a reputation for making better use of plain text than any other operating system. While many tools cater to programmers, writers, and authors can also take advantage of these powerful tools.
[mai mult...]The Windows Subsystem for Linux, or WSL for short, makes it easy to use Linux software inside a Windows PC. You can now officially use Arch Linux in WSL, alongside existing distribution options like Ubuntu, Debian, and Fedora.
[mai mult...]Personalizează-ți experiența WhatsApp pe iOS sau Android prin ajustarea tonului de notificare pentru fiecare persoană în parte.
Fie că e vorba de un prieten, un coleg sau un membru al familiei, poți alege sunetul care îți reflectă cel mai bine relația cu acea persoană, astfel încât să recunoști instant cine îți scrie și să-ți personalizezi modul de reacție.
[mai mult...]Purpose: Detect steganographic payloads in PNG and BMP image files.
What It Is:
zsteg is a Ruby-based tool used to find LSB (Least Significant Bit)-based steganography and hidden data inside image files.
Primarily works on BMP and PNG formats, including non-standard or suspicious metadata and bit-layer anomalies.
Features
Detects:
-LSB steganography (bit-level hidden data in image color channels)
-Embedded files in metadata or unusual file structures.
-Strings, byte patterns, XOR, and Zlib compression artifacts.
-Supports pattern-based payload discovery using known signatures.
Built into Kali Linux
You can run it without installing anything
magic-wormhole is a command-line tool that allows two computers to securely transfer a file or short message through a simple, human-readable code. It is designed to be:
-Easy to use via CLI: wormhole send file.txt → receive with wormhole receive
-Transfers are encrypted, peer-to-peer (or via a relay if needed).
-No user accounts or persistent connections.
-Can send directories (–code, –hide-progress available).
-Works on Linux, macOS, Windows, and even Raspberry Pi.
Real Use Cases:
Share sensitive files securely without needing cloud services.
Drop a script or payload into a target machine in red-team/pentest environments (covert file exfiltration).
Air-gapped environments where traditional networking is blocked but outbound DNS or HTTP exists.
Built into Kali Linux
You can run it without installing anything
How does it work?
1.The sender and receiver each run magic-wormhole in the terminal.
2.The sender is shown a one-time “wormhole code” like 7-orange-tunnel.
3.The receiver enters that same code into their own wormhole command.
4.Both sides use this code to derive a shared cryptographic key using PAKE (Password-Authenticated Key Exchange).
5.This key encrypts the file or message and sends it directly over a secure connection.
It uses:
-SPAKE2 protocol for key agreement.
-libsodium (NaCl) for authenticated encryption (Curve25519 + XSalsa20-Poly1305).
-Transit relay server (if direct peer-to-peer fails).
Discovering Typosquatting Domains with dnstwist
dnstwist is an open-source domain name permutation engine — a typosquatting detection tool used in cybersecurity to identify suspicious or malicious domains that look similar to legitimate ones.
dnstwist generates hundreds of typo variations (e.g., goggle.com, gooogle.com, g00gle.com) based on a target domain and checks:
-If those domains are registered
-Whether they resolve to IP addresses
-If they have DNS, MX, or WHOIS info
-(Optional) Whether they are serving web content, potentially phishing pages
Built into Kali Linux
You can run it without installing anything
Why It’s Useful (in Cybersecurity & OSINT)
-Detect phishing campaigns targeting your brand
-Monitor brand abuse or lookalike domains
-Alert your clients of malicious typosquat domains
-Enhance security posture in red team and blue team scenario
Goal:
Check for domains that look similar to your real domain (like gooogle.com, g00gle.com, etc.). These are often used for phishing, malware, or impersonation — a classic typosquatting tactic.
