While you may not have loads of secret files hiding on your computer, there might be one or two items that need a little extra security, like a file of website logins or a folder of risqué photos.
Welcome back, my fledgling hackers! There's an evil dictator hellbent on destroying the world, and in one of our last hacks, we successfully compromised his computer and saved the world from nuclear annihilation. Then, we covered our tracks so no one would know what we did, and developed a hack to capture screenshots of his computer periodically so we could track of what he was up to next.
WhatsApp sneakily made some security changes to iCloud backups without your knowledge, ladies and gents. Not that strengthening security is a bad thing, but still!
Technology has progressed by leaps and bounds and has blessed people in a number of ways, but at the same time, it has troubled them also. Computers are now used in every aspect of life. No matter if you are a businessman, an employee, a student, or even a housewife, a computer can assist you in your routine work. You save your personal information, documents, and other similar sensitive stuff on your computer that can hurt you if they get compromised.
Welcome back, my fledgling hackers! Awhile back, I demonstrated one of my favorite little tools, netcat, which enables us to create a connection between any two machines and transfer files or spawn a command shell for "owning" the system. Despite the beauty and elegance of this little tool, it has one major drawback—the transfers between the computers can be detected by security devices such as firewalls and an intrusion detection system (IDS).
A tutorial on how to "break in" to your Windows machine after you have lost the password. This works in Windows NT, 2000, and XP machines without an encrypted file system. I then show you how to wipe a hard disk to assure no one can gain access to your data once the drive is sold or discarded.
This is the second episode of Full Disclosure by InfinityExists.com. This episode includes how to crack WEP encryption, and why it can be cracked so easily.
Now that smartphones have ensured that we're connected to the internet 24/7, online privacy has become more important than ever. With data-mining apps hoping to sell your information for targeted ads, and government agencies only one subpoena away from knowing every detail of your private life, encryption has become our last line of defense.
Due to the overnight success of smartphones, millions of people are connecting with others. Currently, over 15 million text messages are sent every minute worldwide. Most of this communication is happening in the open where any hacker can intercept and share in the discussion unbeknownst to the participants. However, we don't need to communicate insecurely.
Oh how we love open source software. If it wasn't for Open Office, we never would have been able to write that seven-page English paper while on our friend's Microsoft Office-lacking laptop during an impromptu road trip to Mexico. And Ubuntu, an open source secure operating system, offers you similar convenience. A much more intuitive computer operating software than your standard Windows or Mac OS, Ubuntu is great if you know what you're doing.
This tutorial series shows you how to put up an Adobe Air Flex 3 Encryption System.

Traditionally, if you were looking for end-to-end encrypted messaging, you'd stick with something like iMessage, WhatsApp, or Signal. However, if you already use Facebook Messenger, you have all you need for truly private chats with its built-in E2E encryption. It's available to all users, on Android and iOS — you just need to know where to look.
As penetration testers, we sometimes need to securely store customer data for prolonged periods. Bruteforce-resistant, vault-like containers can be created with just a few commands to protect ourselves from physical attacks and unintended data disclosures.
As the third-largest smartphone manufacturer in the world, Apple devices are a constant target for hackers everywhere. While iOS has seen fewer common vulnerabilities and exploits (CVEs) in recent years, iPhones still aren't hack-proof. Fortunately, you can strengthen your security with the help of a few apps.
Android has several features built into the platform that improve user experience but require extra attention to prevent a security breach. By modifying these settings, you can drastically reduce the possibility of someone exploiting your device or intercepting information.
This is the very first article in my series on setting up a Mac for hacking. In this series, I will be operating under the assumption that you have a clean install of macOS (previously OS X).

In the wake of the NSA scandal and celebrity-photo hacks, lots of people scrambled to find more-secure ways to send text messages, share emails, and surf the internet. Known for their incredibly secure data networks, Germany's email services saw a remarkable increase in new users from across the world. Last year, we covered Sicher, a German app that lets you send and receive encrypted self-destructing messages on your smartphone.
In February of this year, the Higher Court of Berlin ruled that Facebook must follow strict German data protection laws, which Facebook's terms of services and privacy policies circumvent.
In the wake of the NSA controversy and its subsequent fallout, many dashed towards finding means of secure communication—using private internet browsing and encrypted text messaging applications—out of fear of being spied on.
