Beginner’s Guide to Ethical Hacking Tools 🔐
Ethical hacking is more than a buzzword—it’s a critical skillset in 2025’s cybersecurity landscape. If you’ve ever wondered how hackers think and how companies stay one step ahead of cybercriminals, you need to know the essential tools of the trade. Here’s your beginner’s toolkit:
1. Kali Linux – The Hacker’s Operating System
A Linux distribution packed with security and penetration-testing tools.
Why use it? Pre-installed tools, live-boot capability, regular updates.
Get started: Download the ISO, create a bootable USB, and explore tools like Nmap and Metasploit.
2. Nmap – Network Mapper
Scans networks to discover hosts, services, and vulnerabilities.
bash
CopyEdit
nmap -sS -sV -O target_ip
-sS for stealth scan
-sV to detect service versions
-O for OS detection
3. Metasploit Framework – Exploitation Powerhouse
Automates exploiting known vulnerabilities.
Use case: After identifying an open port with Nmap, launch an exploit module in Metasploit to test the weakness.
Basic commands: bashCopyEditmsfconsole use exploit/windows/smb/ms17_010_eternalblue set RHOST target_ip run
4. Wireshark – Packet Analyzer
Captures and analyzes network traffic in real time.
Why it matters: See exactly what data is flowing across the network—useful for finding unencrypted credentials.
Tip: Apply display filters like http or ftp to focus on specific protocols.
5. Burp Suite – Web Application Scanner
Interacts with web applications to find vulnerabilities (SQLi, XSS, CSRF).
Features: Proxy traffic, automated scanner, intruder for fuzzing.
Getting started: Configure your browser to use Burp’s proxy, then browse the target site to capture requests.
6. John the Ripper – Password Cracker
Tests password strength by performing dictionary and brute-force attacks.
bash
CopyEdit
john --wordlist=/usr/share/wordlists/rockyou.txt hashfile.txt
Tip: Always test on hashes you have permission to crack.
7. Nikto – Web Server Scanner
Checks web servers for dangerous files, outdated software, and misconfigurations.
bash
CopyEdit
nikto -h http://target_website
Quick win: Identify default files and known vulnerabilities in seconds.
8. Aircrack-ng – Wireless Network Auditor
Assesses Wi-Fi network security by capturing and cracking WEP/WPA-PSK keys.
Workflow:
airodump-ng to capture packets
airmon-ng to enable monitor mode
aircrack-ng to crack the handshake
9. OWASP ZAP – Web Vulnerability Scanner
An open-source alternative to Burp Suite with active community support.
Use case: Automated scans plus manual testing of web applications.
Bonus: Integrated API for custom scripting.
10. Hydra – Fast Login Cracker
Performs rapid brute-force attacks on network and web services.
bash
CopyEdit
hydra -l admin -P passwords.txt ssh://target_ip
Warning: Use only in lab environments or with explicit permission.
Putting It into Practice
Set up a lab with virtual machines (Kali Linux + victim OS).
Scan the network with Nmap.
Analyze traffic in Wireshark.
Exploit a vulnerability with Metasploit.
Validate web app security using Burp Suite and OWASP ZAP.
Crack test passwords with John the Ripper and Hydra.

(( @sweetfirecracker!!!!!!!!!! [many hugs] I had a lot of trouble picking a pairing for this. And then I fudged a little. ))
Starlight’s fist slammed into the machine, through the metal and into its mechanical heart. She yanked out a fistful of cables and components and, with some slight sparking, the lights on the machine dimmed, flickered, and went dark.
The whirling buzzsaw blade stopped inches from his chest, and Shiro took his first breath in what felt like years. 
But there was little time to thank her when she was already surrounded by bad guys again. She was pulling her punches this time, careful not to kill the fragile men who surrounded her with her super-strength. 
Fortunately, Shiro was a pro at this whole “being tied to a chair” thing. He hopped the chair backwards a little, enough so that he could start trying to turn it around. This is a lot harder than I thought. Maybe I’m not ready for the Pro Chair Hopping League yet after all. He kept at it.
One of the gang members slid past him along the floor and hit the wall. He was already unconscious before he hit the bricks. Starlight must still be hogging the spotlight, which was just what Shiro needed. He started hopping the chair backwards, until one of the teeth of the sawblade nicked his finger. “There we go,” he muttered under his breath, and began rubbing the ropes binding his wrists against the sharp blade that had been about to kill him.
The ropes loosened and he began scrabbling to get himself free. He still had to untie his ankles himself, but once that was done, he stood and stretched the tension out, feeling circulation start to resume its normal course.
“ARE YOU FREE?” Starlight’s voice called above the din of punching and kicking.
“YES!” he yelled back.
“GOOD! GET OUT OF HERE!”
“NOT WITHOUT MY STORY!”  Now that he knew his legs would hold him, he ran for the other room. He paused by the gang member who was out cold and fetched up against the wall. “Hey, you’re the one who took my phone!” He fished around in the man’s pockets until he found it and then took off again. He had evidence to document.
He could already hear Ms. Fala in his head, nagging at him about the idiotic risks he undertook. “I swear this paper couldn’t publish news worth a damn if it weren’t for Starlight rescuing you all the time.” He couldn’t really say she was wrong, but dammit, he went where the story was. It wasn’t his fault that he kept getting captured. I was an Air Force pilot, not a stealth expert. 
And though she’d nag him, he knew Ms. Fala would be thrilled with the evidence he was collecting. He kept a mostly-empty USB drive on him when he was out snooping, and he plugged it into the computer. Pidge had put a password cracker on there, and it went to work. And once he was in, he started copying over the files. Drugs, guns, illegal gambling, even the strange experiments their boss was conducting. It’s all here. 
While the files copied, he took pictures of the hideout. They weren’t much on their own, but every photo would have a geo-location on it, automatically tagged by the phone. With this, the police could verify everything he’d given them. 
The soft ping told him the files were done copying. He grabbed the USB drive and headed for the door...
...before nearly running right into Starlight. She stood there and frowned at him. “I told you to leave.”
“Punching them is all well and good, but there has to be verifiable evidence, or no one gets convicted.”
“And because you had to get your story.”
“That, too.” He grinned.
She shook her head. “Well, you have your story so get out now. And maybe take the weekend off? I do have crime to stop that isn’t centered around you.”
He shrugged. “We’ll see. I did promise my boyfriend a dinner out at some point.”
“Make it a dinner in,” she told him. “You’re far less likely to get caught in some criminal’s crossfire that way.”
“But where’s the fun in that?”
She rolled her eyes. “Good-bye, Shiro. Take care of yourself.”
He watched her walk out. “And thanks, y’know,” he said quietly.
“You’re welcome,” she called back over her shoulder.

#1yrago Origin story of the Mimikatz password cracker is a parable about security, disclosure, cyberwar, and crime
Tumblr media
Five years ago, Benjamin Delpy was working for an unspecified French government agency and teaching himself to program in C, and had discovered a vital flaw in the way that Windows protected its users' passwords.
Delpy told Microsoft about his discovery, only to be rebuffed by Microsoft's engineering team, who told him that his security discovery was irrelevant because it would be too hard to exploit. As a way of proving his point and improving his C, he coded up Mimikatz ("Cute Cat"), a password stealing tool that has since grown into an "insanely powerful" Swiss Army Knife of Windows password-cracking.
Delpy released the sourcecode for Mimikatz after traveling to Russia to present on it at the Positive Hack Days conference in Moscow; that's because, while he was there, Russian spies repeatedly came after his code. First, he walked in on a spy who was physically tampering with his laptop while it was in his hotel room, then a "man in a dark suit" insisted that he put a copy of his presentation and sourcecode on a USB stick.
Andy Greenberg's Wired profile of Delpy exposes the complicated world of security research and disclosures. Companies would like to be able to control who can disclose defects in their products. Large firms have previously abused laws like the Computer Fraud and Abuse Act and Section 1201 of the Digital Millennium Copyright Act to threaten (and even jail) security researchers who disclosed true facts about errors in their code. Most recently, the largest tech companies on earth explicitly rejected a proposal that would have protected security researchers who went public with information about defects in browsers used by billions of people.
Delpy makes sure that he notifies Microsoft before he updates Mimikatz, but Microsoft sometimes insists that his discoveries aren't real problems. Without Delpy's public disclosures, the general public would have no way to know that these bugs existed and could be used to attack them. Security experts rely on Delpy's tool to evaluate whether their client's systems are well-secured.
But crooks also use Mimikatz. It has been folded into NSA hacking tools that have leaked into the public domain, and used by Russian spies to hack the German Parliament.
As Greenberg's experts say, though: if Delpy hadn't gone public with his bugs, someone else would have, and may not have been so willing to share their discoveries with the good guys who are trying to secure, rather than compromise, our systems.

Winrar Png
Tumblr media
Archiving utilities such as WinRAR, WinZip or 7Zip are useful for compressing large files into smaller ones to send as email attachments to someone who can extract them using a similar tool, or store on USB flash drives with a limited capacity to transfer to another computer, for example. There are endless advantages to such tools.
Winrar Png Icon
Winrar Permissions
PNG is a lossy format on its own, and after conversion to JPG the quality of image may be notably worsened. PNG to JPG Converter features progressive compression algorithms that help to preserve the original quality of images. However, you can still decrease the file size or scale images for optimization purposes. Get free Winrar icons in iOS, Material, Windows and other design styles for web, mobile, and graphic design projects. These free images are pixel perfect to fit your design and available in both PNG and vector. Download icons in all formats or edit them for your designs. Also, be sure to check out new icons and popular icons. The recommended size of a high-resolution logo PNG file is 186×604 pixels. Crack for WinRAR 6 included inside the package. New “Clear history” command in the “Options” menu. Ctrl+C and Ctrl+Ins keyboard shortcuts can be used in “Diagnostic messages”. The photos you provided may be used to improve Bing image processing services. This Winrar Zip Archive Password Cracker Online - Winrar is high quality PNG picture material, which can be used for your creative projects or simply as a decoration for your design & website content. Winrar Zip Archive Password Cracker Online - Winrar is a totally free PNG image with transparent background and its resolution is 910x215.
Tumblr media
When it comes to creating archives, though, there are many properties that can be taken into account, such as file type, compression mode, file checksums, and backups. Most casual users opt for the default, 'as is' configuration simply because it's faster and easier to understand.
However, learning about these parameters is essential for maximizing an archiver's efficiency and getting optimal results. It depends on what you're trying to compress, how much time you're willing to spend waiting for the task, and what amount of memory you're willing to spare when working with other applications at the same time.
Getting started with WinRAR
In the following guide, we're going to show you what type of compression to choose when putting together archives using WinRAR.
Get started by launching WinRar and clicking Add on the toolbar. This brings up the Archive name and parameters window, where you can click the Browse button to set the name and saving location of the new archive.
Archive format options
You can pick from three Archiveformat options: RAR, RAR5, and ZIP. If you want to send the resulted archive to someone else, you should take into account the archive extraction tool they might be using. ZIP is the safest option because it's more common than RAR and RAR5, thus supported by many extraction applications. RAR has additional customization settings as compared to ZIP (since it's WinRAR's proprietary format) while RAR5 is the newest file type of WinRAR, which brings a lot of improvements but isn't supported by versions older than WinRAR 5.0, so you must keep the compatibility factor in mind.
Compression methods
There are six Compression methods available: Store, Fastest, Fast, Normal, Good, and Best.
Normal is set by default and can be considered the baseline. For example, if you opt for archiving files in Windows Explorer by opening the right-click menu and clicking Add to 'Folder_name.rar', the normal compression mode is applied. It's a balance between speed and compression, suitable for day-to-day activities on the go, such as sending email attachments at work.
Store Free text effects after effects. adds the files to the archive as fast as it can but doesn't compress them at all. It's practical for storing multiple files into a single one (a container) that can be transferred to an external device faster than copying multiple files at once. It's the ideal mode for batches of documents or pictures that take little disk space. Besides, it's not possible to reduce the size of JPG and PNG files since they are already compressed by design.
Tumblr media
The Fastest compression method is a bit slower than Store because it applies some degree of compression, although it's poor. Fast is slower than Fastest but speedier than Normal, and it applies better compression than Fastest but weaker than Normal. These two can be used for frequent data backups.
The Good compression mode can be used for large files that take up a lot of space. It can create archives with a significantly smaller size, but it takes a while. Winrar do.
Best takes compression to the highest level, but it's very slow. It's ideal if you want to save space and if you have the possibility of leaving your computer unattended so that it can take care of the archiving job without being slowed down by the activity of other programs, due to the fact that it uses a lot of memory. To speed it up and prevent it from hanging, make sure to close any other running applications.
Dictionary size and Create solid archive
Tumblr media
Aside from the compression method, the ZIP filetype doesn't have other options that can be configured to influence performance. However, you can maximize the Dictionary size for RAR5 if you want to compress large files to get minimum file size, especially if Create solid archive is enabled (more on this next). You should keep in mind that it's a very slow and memory-demanding process.
If you tick the Create solid archive box to activate it, WinRAR delivers better compression results if there are many similar files. On the other hand, any further modifications you make to the archive (e.g. removing files or adding new ones) will be slower, and the chances of successfully recovering data in case of archive damage are slimmed down. It can be used for storing backups of the operating system, for instance.

Perché un criminale informatico dovrebbe scegliere proprio me?
Un nuovo post è stato pubblicato su https://www.staipa.it/blog/perche-un-criminale-informatico-dovrebbe-scegliere-proprio-me/
Perché un criminale informatico dovrebbe scegliere proprio me?
Tumblr media
Ogni volta che un informatico prova a spiegare a qualcuno perché è bene usare password robuste, perché è bene avere il sistema operativo dello smartphone o del pc aggiornati, perché usare un browser moderno invece di uno antico e fuori supporto, perché dismettere Windows XP, Vista o Windows 7, perché attivare un buon antivirus ovunque anche sul Mac, la risposta è quasi sempre “tanto non ho nulla da nascondere”, o “perché un hacker dovrebbe attaccare me?”.
I motivi purtroppo sono moltissimi e cercherò di riassumerne alcuni dei più semplici in maniera chiara. In questo articolo ovviamente assumerò che chi legge non abbia sul computer o sullo smartphone:
informazioni delle carte di credito
foto private che non vorrebbe venissero divulgate
Informazioni, mail, comunicazioni private che non vorrebbe venissero divulgate
perché per ovvi motivi se avete qualcosa di queste, già il fatto di condividerle con uno sconosciuto dovrebbe rendervi inquieti.
Nei decenni il concetto di virus informatico, di cui magari parlerò in un altro articolo, si è estremamente evoluto. Se nei primi decenni della storia di questo genere di attacchi tendevano ad essere visibili e lampanti con messaggi, cancellazione di file importanti, danni estremi al sistema, malfunzionamenti oggi il più grande risultato che un Cracker (si, gli informatici cattivoni sono i Cracker, non gli Hacker, ma anche di questo parleremo in un altro articolo) è creare un virus che sia il più possibile invisibile, sia agli antivirus che soprattutto agli utenti. Se in un primo tempo il divertimento era soprattutto quello di diventare famosi con un’attacco che restasse nella storia o di bloccare un pc per renderlo inservibile dando fastidio all’utente ora il cracking è diventata un’operazione decisamente più su vasta scala e industrializzata.
C’è un solo caso oggi in cui il virus deve essere visibile.
I Ransomware
I Ransomware sono una categoria una categoria di virus venuti alla ribalta relativamente di recente anche se probabilmente il primo fu il trojan AIDS, scritto nel lontano 1989. I più famosi sono senza dubbio Reveton, CryptoLocker e WannaCry. Hanno diversi funzionamenti ma dal punto di vista dell’utente si possono riassumere fondamentalmente in uno.
Il virus viene ricevuto da mail, dalla connessione a una rete infetta (potrebbe essere anche il wifi di un bar, quello di un’azienda, quello del proprio vicino di casa che ha ricevuto a sua volta il virus via mail o da un’altra fonte), da messaggistica immediata, da chiavetta usb o da altre fonti.
Il virus cripta tutti i dati del vostro dispositivo e di tutti i dispositivi collegati (hard disk, chiavette usb, NAS). Per criptare o cifrare si intende rendere illeggibili se non tramite l’inserimento di una password ignota, un po’ quello che tutti abbiamo fatto da piccoli scambiando le lettere dell’alfabeto per mandare messaggi segreti a qualche amichetto, con la differenza che il sistema per cifrare i dati è decisamente più complesso
Il virus tenta di infettare altri dispositivi connessi alla stessa rete o di conoscenti presenti nella rubrica
Il virus mostra un messaggio in cui viene chiesto il pagamento di un riscatto economico per poter rientrare in possesso dei vostri dati
A questo punto, se il danno è fatto, nella gran parte dei casi non c’è più speranza. Ne il miglior antivirus del mondo, ne il vostro amico informatico di fiducia saranno più in grado di recuperare i vostri dati. Le migliaia di foto che avete raccolto negli anni, i vostri preziosissimi mp3, i vostri giga di film (sicuramente acquistati legalmente) sono perduti a meno di sottostare alle regole e inviare il pagamento online.
Non c’è modo di decrittare i dati se non usando la password (le loro sono complicate davvero) che vi potrebbe essere fornita se pagaste. Dico potrebbe, perché come è facile immaginare l’etica di un cracker non lo porta necessariamente ad essere leale, potrebbe anche non aver mai creato tale password, o non fornirvela neanche dopo il pagamento. Wannacry ad esempio ha infettato aziende come Portugal Telecom, Deutsche Bahn, FedEx, Telefónica, Tuenti, Renault, National Health Service, il Ministero dell’interno russo, l’Università degli Studi di Milano-Bicocca, con oltre 230.000 computer in 150 paesi, è considerato un dei contagi da virus informatico più estesi della storia.
Esiste modo di proteggersi da questo rischio? Sì: aggiornando sempre il proprio sistema, stando attenti a cosa si scarica e a quali reti wifi ci si collega, utilizzando un robusto antivirus, ma soprattutto avendo sempre una copia periodica di backup offline. Che cosa significa una copia periodica di backup offline? Semplicemente un Hard Disk, possibilmente fisico, in cui copiare tutto quello che volete salvare da tenere attaccato al computer solamente il tempo di tale copia, in modo che in caso di attacco ransomware il virus non lo trovi collegato al pc. Google Drive, DropBox, OneDrive e altri sistemi di questo genere sono sufficienti? In genere no. A meno che non li utilizziate appunto senza collegamento diretto al vostro pc i files criptati dal virus sul disco verranno aggiornati anche su questi servizi remoti. L’unico supporto che questi sono in grado di dare, limitatamente al tipo di servizio offerto, è quello di recuperare versioni vecchie dei file e questo potrebbe aiutare, se il servizio non ha limiti di quantità, spazio, tempo di archiviazione, o un servizio (generalmente nei pacchetti a pagamento) specifico per i ransomware.
Le botnet e i computer zombie
La grande maggioranza dei virus di oggi sono invece invisibili, consumano meno risorse possibili, fanno meno danni possibili al vostro sistema, e fanno tutto il possibile per non essere visti. A questo punto vi chiederete cosa fanno. Se qualcuno volesse avere una potenza di attacco informatico tale da bloccare un sistema gigantesco e distribuito come quello di uno dei grandi big dell’informatica come Google, Amazon, Microsoft, Apple, o da bloccare la rete di un’intera nazione, in linea teorica dovrebbe possedere migliaia, meglio milioni di computer sparsi su tutto il territorio mondiale e coordinare un attacco da tutti questi computer nello stesso momento. Roba da fantascienza, no? Solo Google avrebbe abbastanza risorse per attaccare Amazon, solo Microsoft potrebbe avere abbastanza risorse per attaccare Google, eccetera. Eppure c’è chi possiede quantità di computer più che sufficienti allo scopo e ad aver subito attacchi del genere tra gli altri ci sono Twitter, Netflix, Spotify e PayPal, probabilmente il governo degli Stati Uniti (Le novità sull’attacco informatico contro il governo statunitense – Il Post – https://tinyurl.com/ybzb9noo). Chi possiede questa quantità di computer? Esistono aziende che fabbricano virus in grado di prendere il controllo in maniera silente di milioni di computer in contemporanea, se il vostro computer è affetto da questo tipo di infezione non farà assolutamente nulla di strano, soprattutto non lo farà mentre magari state usando le risorse al massimo giocando al Cyberpunk 2020 o montando un enorme video un FullMegaGigaHD, lo farà quando non lo state usando, quando state solamente navigando stancamente sui social, o mandando una mail. Il vostro pc potrebbe essere parte di una di queste botnet, reti di pc zombie, inerti che sono in realtà agenti segreti alla the bourne identity, pronti a essere svegliati e usati per un attacco magari anche per solo cinque minuti per svolgere qualche attività criminale, per far girare immagini pedopornografiche rendendo difficili le indagini e rendendovi virtualmente complici, per fare da routing (passacarte) di comunicazioni terroristiche. Il limite è solo della fantasia di chi possiede la botnet. Non serve neppure possederla tra l’altro, esistono società criminali in grado di noleggiare porzioni di botnet, e a seconda del tipo di attacco che deve essere fatto sono in grado di fornire la giusta quantità di computer posizionati nelle giuste zone. Necurs per esempio è stata una botnet composta da oltre nove milioni di computer di utenti inconsapevoli, e per essere smantellata è dovuta intervenire Microsoft collaborando con 35 nazioni diverse (https://tinyurl.com/y9qjfhmc), la rete per altro non è “cancellabile” perché non è possibile agire su ogni singolo computer, per tanto l’unico modo che si è trovato è quello di prenderne il controllo in modo che non possa più essere usata per fare danni. Di questi nove milioni di utenti probabilmente nessuno o quasi sa che il proprio computer appartiene a quella botnet.
Quanti reati potete immaginare di fare con nove milioni di computer a vostra disposizione?
La stessa cosa ovviamente è fattibile con semplici account social. Se usate una password eccessivamente semplice da scovare (qui una classifica delle più usate e rubate: https://tinyurl.com/y9trgqhs), è facile che il vostro account entri venga violato silenziosamente e utilizzato per dare, di tanto in tanto, senza esagerare per non farvene accorgere, like o recensioni a pagine che pagano per ricevere notorietà illegalmente, o-magari essere coinvolti in qualche altro genere di attività illecita. Oppure il vostro indirizzo mail può essere usato per mandare mail pericolose ma perfettamente credibili, in quanto provenienti da un indirizzo rispettabile e magari conosciuto.
Perché un criminale informatico dovrebbe scegliere proprio me?
Perché tu saresti uno in più per ingrandire un’enorme rete di complici involontari per reati gravi. Perché tu potresti essere uno delle migliaia a cui provare a spillare soldi per riavere i propri dati. Perché se tra centinaia di migliaia di tentativi anche solo un 1% va a buon fine significa che ne sono andati a buon fine migliaia. Perché se è vero che probabilmente verresti scagionato da qualunque accusa non è bello rischiare dover consegnare il propri dispositivi alle forze dell’ordine e averli sequestrati per il tempo delle indagini e con le conseguenze relative in perdita di tempo e sanità mentale.

Origin story of the Mimikatz password cracker is a parable about security, disclosure, cyberwar, and crime
Tumblr media
Five years ago, Benjamin Delpy was working for an unspecified French government agency and teaching himself to program in C, and had discovered a vital flaw in the way that Windows protected its users' passwords.
Delpy told Microsoft about his discovery, only to be rebuffed by Microsoft's engineering team, who told him that his security discovery was irrelevant because it would be too hard to exploit. As a way of proving his point and improving his C, he coded up Mimikatz ("Cute Cat"), a password stealing tool that has since grown into an "insanely powerful" Swiss Army Knife of Windows password-cracking.
Delpy released the sourcecode for Mimikatz before traveling to Russia to present on it at the Positive Hack Days conference in Moscow; nevertheless, while he was there, Russian spies repeatedly came after his code. First, he walked in on a spy who was physically tampering with his laptop while it was in his hotel room, then a "man in a dark suit" insisted that he put a copy of his presentation and sourcecode on a USB stick.
Andy Greenberg's Wired profile of Delpy exposes the complicated world of security research and disclosures. Companies would like to be able to control who can disclose defects in their products. Large firms have previously abused laws like the Computer Fraud and Abuse Act and Section 1201 of the Digital Millennium Copyright Act to threaten (and even jail) security researchers who disclosed true facts about errors in their code. Most recently, the largest tech companies on earth explicitly rejected a proposalthat would have protected security researchers who went public with information about defects in browsers used by billions of people.
Delpy makes sure that he notifies Microsoft before he updates Mimikatz, but Microsoft sometimes insists that his discoveries aren't real problems. Without Delpy's public disclosures, the general public would have no way to know that these bugs existed and could be used to attack them. Security experts rely on Delpy's tool to evaluate whether their client's systems are well-secured.
But crooks also use Mimikatz. It has been folded into NSA hacking tools that have leaked into the public domain, and used by Russian spies to hack the German Parliament.
As Greenberg's experts say, though: if Delpy hadn't gone public with his bugs, someone else would have, and may not have been so willing to share their discoveries with the good guys who are trying to secure, rather than compromise, our systems.

Programmi, Dispositivi e Tecniche dell’Hacking
Negli ultimi anni il mondo ha assistito ad una crescita esponenziale dei sistemi e dispositivi informatici. Con una rapida evoluzione sia nell’ ambito di software e dispositivi hardware per le macchine informatiche, che nei dispositivi di hacking. Inoltre la diffusione di criptovalute come i bitcoin, moneta non rintracciabile, ha aumentato le possibilità di accesso ai dispositivi usati per criptare e bypassare sistemi di sicurezza, aumentando la pericolosità dei cyber criminali.
Infatti, con l’introduzione di alcuni dispositivi di hacking quali: il password wireless cracker, l’antminer s4 bitcoin mining, la keyllama keylogger usb e il roadmasster-3 forense, si intensificarono gli attacchi hacker.
Per esempio la keyllama keylogger usb è una unità flash usb che, non richiedono alcun software per funzionare, si attiva nel momento in cui viene inserita nel computer. Essendo compatibile con qualsiasi massa è in grado di diffondere malware non appena viene inserita.

Però la vera pericolosità dell’hacking non sono i dispositivi hardware ma i software.
Infatti, con l’ausilio di numerosi programmi, come ad esempio il backtrack, gli hacker possono infettare, spiare e controllare i computer in remoto. I programmi più diffusi, utilizzati per questo fine, sono:
1) Nmap: software creato per effettuare il port-scanning, cioè mirato all’  individuazione di “porte” aperte su un computer bersaglio o su indirizzi IP, in modo da determinare quali servizi di rete sono disponibili.
2) Backtrack: dispositivo che permette di avere un unico “portale” per accedere ai software di sicurezza e rete.
3) Metasploit: framework di vaste dimensioni che, con tools come paylad e exploit, può colpire numerosi sistemi di sicurezza.
4) Shell c99/r54: due tipologie di shell php; sono script simili a backdoor  e consistono nell’ includere, in una pagina web, il contenuto di un’altra pagina.
Con le shell php gli hacker possono diffondere facilmente i worm e i virus tramite il comando include().

Infatti, a causa delle shell php, numerosi computer sono stati infettati dai worm: famiglia di malware  che diffondendosi attraverso la rete (specialmente la lan) si possono introdurre facilmente nel computer bersaglio.
Essi modificano il sistema operativo della macchina ospitante e si avviano nel momento in cui viene acceso i computer. Attaccano il disco rigido rallentandone il funzionamento e talvolta portandolo a fondere causando la perdita dei dati. Sono spesso accompagnati da malware come i trojan horse o le backdoor, che attraverso pop up su internet, creano varchi nei sistemi di sicurezza diffondendo virus o worm senza che l’utente se ne accorga.
Uno degli attacchi hacker più famosi, che sfrutta a pieno il meccanismo backdoor e worm, è il Wannacry.

Kali Linux has more than 600 inbuilt programs for Penetration Test. It includes Armitage ( Armitage is a Graphic Cyber Attack Management Tool), John the Ripper ( It is a Password Cracker Tool ), Nmap ( Port Scanner Tool ), Aircrack-ng ( It is a software to perform Penetration Test on Wireless LANs ), Burp Suite and web application security such as Burp Suite and OWASP ZAP.
It was developed by Offensive Security. It was created by Mati Aharoni and Devon Kearns by rewriting BackTrack. BackTrack was the previous tool which was used for security testing and it was based on Knoppix. Initially Kali Linux was designed for only kernel auditing from it was named as Kernel Auditing Linux.
Kali Linux is based on Debian Testing Branch. Mostly the packages of Kali Linux which are put to use is imported from Debian repositories.
Kali Linux grew popular when it was featured in multiple episodes of a T.V. Series called Mr. Robot. The tools of Kali Linux which were highlighted in the show were Bluesniff, Bluetooth Scanner, btscanner, John the Ripper, Metasploit Framework, shellshock, Wget and Nmap.
What are the Requirements for Kali Linux ?
• Minimum of 3GB Hard-Disk space is needed for installation of Kali Linux
• Minimum 256MB of RAM for i386 and AMD64 architecture
• A Bootable CD or DvD or a USB
What is Mostly Recommend :-
• You need 20GB of free space on your Hard-Disk, SSD is preferred over Hard-Disk
• A minimum of 2GB RAM i.e. 2048MB
