HACK File Shredder
Hackers sometimes breach your computer to steal data, other times they wait for the data to come to them. Keyloggers are malicious spyware programs that record every keystroke you make and relay it back to the hacker. So, when you type in your bank details, log into social media, or use your credit card online, they know exactly what you typed.
This is how apps like Undeleter are able to recover deleted files, and it's how government agencies are able to pull data off of wiped hard drives. It's an obvious security risk, so developer Giuseppe Romano stepped in with an app that will plug up this loophole.
The app works by overwriting empty space on your storage drive with random bits of data, then deleting the end product. As a result, any files you've previously deleted will be permanently erased, making it virtually impossible for anyone to recover the data.
The app that lets you permanently erase deleted files is called Secure Eraser, and it's available for free on the Google Play Store. To begin, search the app by name and get it installed, or head directly to the install page at the following link:
When you've got that part taken care of, go ahead and tap the "Start" button near the bottom of the screen to begin erasing your deleted files. From here, Secure Eraser will overwrite any empty space with random data to get rid of your old deleted files.
This process can take quite a while, so try doing this whenever you don't need your phone/tablet for a bit. For instance, it took about thirty minutes to fully clean 15 GB of empty space on my test run. Total time will vary depending on the amount of available space on your device, but when it's done, you can rest assured that all of your deleted files are gone for good.
If you want to completely delete a file, you'd have to write /dev/random 3 times on it, then /dev/zero 5 times. The fact that this app uses only 30 minutes to fully clean 15 GB tells me an agency can recover it anyway. Even strong computers would take at least 3 hours to fully delete 15 GB. The question here is how likely it is that the NSA is going to 'undelete' apps on your phone.
Perhaps this is a silly question but I've always been told "No question is stupid, or silly, and it's good to ask questions". With that said, I would think if all files I have deleted are still somewhere on my device they are taking up space. Does anyone know if this app tells you how much space, and/or how many files, will be erased prior to clicking start so you know how much space you will be freeing up? Or, does this not apply..for some reason?
The bytes for your deleted files may still exist (until overwritten by new files), but they'll exist in a space the file index has flagged as free... So no, you won't get any extra space by permanently deleting your already deleted files.
Wouldn't it be easier to just take videos or pics until the memory is filled, and then just delete them. Then the only thing that will be recoverable are files you don't care about. Am I missing something here?
File shredding is the equivalent of shredding a paper document and it makes sure your old files are gone for good.Even if you delete a file, it can still be retrieved and accessed as the data is still in the storage medium. If you throw out or sell your equipment, deleted files can still be recovered.In this video, Dr Nick Patterson demonstrates how to use the tool File Shredder to permanently obliterate old or unwanted files.Your taskWatch the video and think about how you might use a file shredder. Are there guidelines or a process you can put in place that mandates what and when files need to be shredded? Share your ideas in the comments.
When you delete a file from your Android phone, it actually remains in your device's storage until it's overwritten with new data. This used to be a major privacy concern because it meant that deleted files could be retrieved using data recovery software.
Since Android 6 (Marshmallow), all Android phones are encrypted by default, preventing recovery tools from accessing their contents. But if you're still concerned about sensitive files falling into the wrong hands, we'll explain how to erase your deleted data permanently.
The worst way to delete a private file from your Android phone is from within the associated app. This risks the item being moved to a Trash or Bin folder rather than being permanently removed or continuing to exist as a synced cloud copy.
A much better option is to use a file explorer or file manager app to delete sensitive items permanently. There are lots of free file explorers for Android, including Google's own excellent Files app.
Select the item in your file explorer. Then, tap the trash button or press the three-dot menu and choose Delete. Confirm you understand deletion can't be undone and tap Delete again. This is how you should delete your files on Android.
If your phone's encryption doesn't reassure you that deleted files can't be recovered, or if you're running an old version of Android, consider installing a file shredder. This will securely erase "free" space on your device that may still contain deleted data.
File shredders such as iShredder, Shreddit, and Data Eraser offer a choice of shredding algorithms. This lets you decide how many times the data is overwritten with random characters. Each overwrite is known as a "pass" or "cycle," and the more passes, the slimmer the chance deleted data can be retrieved.
You'll need to grant these apps permission to access your files (and optionally your contacts, which we wouldn't recommend), but they won't shred anything without asking you for confirmation. You can use these apps for managing app permissions on Android.
If you don't want to install an app to delete a file permanently, you can connect your Android phone to your PC and wipe the data via Windows. This method makes finding and confidently removing specific items easier using File Explorer. If you are not sure, here is how you can access and transfer files from Android to PC.
Connect your phone using a USB cable and choose Open device to view files from the AutoPlay options. Alternatively, open File Explorer, select This PC, and double-click your phone's drive icon.
If the drive looks empty, pull down the notification tray from the top of your phone's screen, tap USB charging this device, and select File transfer or Transfer files. Or, go to Settings > Connected devices > USB and enable the option there.
Right-click the item, choose Delete, and confirm you want to delete it permanently. Note that the file won't be sent to the Windows Recycle Bin but will be gone for good. If you are wondering how to erase all your data safely from your phone, this is a solid option.
First, go to Settings > Storage > SD card. Locate the file and delete it from there. However, this won't make it unrecoverable, so you may want to format the card, too. This will completely wipe its contents, so make sure you move any files you want to keep to your phone first.
The most drastic way to permanently delete private files is to perform a factory reset. This will erase all the data on your phone, so it is best used prior to selling or recycling your device. You should back up any Android data you want to keep beforehand.
When prompted, enter your security code or pattern, then tap Delete all data to restore your phone to factory settings. You can wipe its free space with a file shredder if you're still paranoid about your data being recovered. But this is pretty much how you can delete all your data from your phone.
Nobody wants their private files to fall into the hands of snoopers and hackers. Although Android's built-in encryption should make your deleted data unrecoverable, trying the other methods we've outlined will give you total peace of mind.
Of course, this all works both ways. Sometimes, you'll delete files by mistake. If you act quickly enough and get the right tools, you will still be able to recover those deleted photos and other data.

I just learned about Kon Boot (from this YouTube video) and am wondering, how is such a hack tool guarded against? In the video the presenter claimed he had full disk encryption but was still able to by pass the password from booting to the USB stick and then had access to the files.
Getting caught is exactly what every hacker does not want. They want to be able to gain entry into a system and then quickly withdraw to the safety of the internet café they are presumably hacking from. Logs are designed to record nearly everything that occurs in a system, including hacking attempts, and can be the determinative factor in catching hackers after their crime has been committed.
Ethical hackers need to understand how hackers tamper with logs, as it is a common practice with hackers. This article will detail the basics of log tampering for ethical hackers, including disabling auditing, clearing logs, modifying logs and erasing command history. The focus will be on Windows and Linux logs, as they are the most used by organizations.
