Smart hackers don’t get caught. They break into your device, steal everything they can, and finish without a trace. Sometimes they leave a trail of destruction in their wake – malware, weird ads, confused relatives, and even a drained bank account or stolen identity.
- Oct 17, 2017 Why It Doesn’t Make Your Network More Secure. The main reason why it doesn’t make your network more secure is because it’s really easy to spoof a MAC address.A network hacker, which can literally be anyone since the tools are so easy to use, can easily figure out the MAC addresses on your network and then spoof that address onto their computer.
- It is not easy to tell if your computer has been hacked but it is extremely unlikely for any Mac to get hacked because they have the best security of all personal computers in the world. The only likely way to hack your Mac would be if you allowed.
- Mar 09, 2015 This type of activity can signal that someone is actively controlling your computer from a remote connection. If you see something like this occurring, immediately disconnect your computer from the Internet and run a complete antivirus scan of the computer to try to remove the software the hacker was using to remotely access it.
- As a Cyber Investigation group, we have built a team of hacking forensic specialists and top internet attorneys with the goal of helping our clients develop the evidence they need to file a law suit or to take to the police. In most of our cases we are able to determine the methods of attacks, develop the required evidence, and in many cases.
- Free tools to find out if your computer is infected with Hacking Team malware Rook Security offers Milano, a free tool to scan your PC for any possible Hacking Team malware infection.
- If you see that suspicious computer talking to a strange IP address, use the nslookup command (in the command prompt in Windows, or in a terminal in OS X or Linux) to get its hostname.
In fact, you can actually track people with this method if you really wanted to. For example, if I know the MAC address of my neighbors phone (which I could easily figure out) I could actually set up a computer that would watch for his MAC address and actually log when he leaves home (goes out of range) and when he gets home (back in range).
It’s pretty easy for hackers to do their job. Most people are ambivalent, but you don’t have to be. Click here for 5 security mistakes you’re probably making right now.
Computers, phones, routers, and down to the innocent webcam are vulnerable to cyber-criminals. So what if they’ve already broken in, yet you don’t even know they’re there? Here are clear-cut signs that you've been hacked.
1. Your gadget suddenly slows down
One of the side-effects of malicious software is a slow gadget. Software gets sluggish, or constantly freezes, or even crashes. If you start noticing some of these symptoms, your gadget may very well be infected with viruses, trojans or worms.
Malicious software usually runs in the background, secretly eating up your gadget's resources while it's active.
Here are tools you can use to pinpoint those nasty applications. If an application that you don't recognize is hogging your computer resources, it's likely a virus.
PC: Use Task Manager
There are a few ways to see what processes your computer is running. The easiest is to bring up Windows' built-in Task Manager. Just use the keyboard shortcut CTRL + SHIFT + ESC and go to the Processes tab.
Put simply, the Task Manager lists all of your computer’s current tasks and how much processing power they’re using, measured in Central Processing Units (CPUs). Open up Task Manager and check the CPU and memory columns for each process.
You might find one process is using 100% — or close to it — of your CPU. Open up the program associated with the process and see what it's doing. Restart the task and monitor it, but this program might be the culprit.

Mac: Use Activity Monitor
The Mac equivalent to Task Manager is its built-in Activity Monitor. The quickest way to access the Activity Monitor is by using Spotlight Search.
Click the magnifying glass on the right side of the menu bar at the top of your screen, or press Command + Spacebar to open a Spotlight window and start typing the first few letters to auto-complete 'Activity Monitor.' Just press Enter to access the tool.
Similar to Window's Task Manager, Mac's Activity Monitor displays a list of all your open processes with tabs for CPU, Threads, Idle Wake Ups and Network usage.
Learn these three troubleshooting Mac shortcuts the pros use.
If this happens when you are on an iPhone, try a soft reset by holding the power and the home button until it reboots with the Apple logo. This step can clear out frozen apps that can be hogging your memory.
2. You’re using way more data than usual
Every Internet provider has tools that can keep track of your monthly bandwidth consumption. Look at Data Usage Meter or Data Monitor, depending on your provider. Compare the amount of data used from the prior months, and if you notice sudden spikes in your data activity even though you haven't changed your patterns, then chances are you are infected.
For example, adware infected gadgets usually perform unsolicited clicks in the background to generate profit for cybercriminals. These stealthy tactics use up bandwidth and the unauthorized data they consume should be fairly easy to spot.
Do you want to save on your data consumption? Here are 5 steps to cut your data usage in half.

3. Videos suddenly buffer and web pages take forever to load
When a streaming video suddenly freezes, and your device appears to be “thinking,” this is called buffering. This annoyance often happens, especially if you play a lot of videos or your Wi-Fi connection is weak. If it’s happening a lot, or videos fail to play at all, you’re wise to suspect neighbors are piggy-backing on your connection. Click here for steps on how to check for Wi-Fi thieves.
Then again, malware can also slow down your Internet traffic by DNS hijacking. In short, hackers can redirect your Internet traffic to unsafe servers instead of the secure servers. This will not only slow down your browsing experience, it's also a serious security risk. For example, if your router's DNS settings have been hijacked, each time you visit your online bank's website, you'll be redirected to a phishing website instead.
To check your router's DNS settings, you can use an online tool like F-Secure Router. For more security, consider changing your DNS server to one with advanced hijacking protection like CloudFlare or Quad9.

4. Programs and apps start crashing
Now, here is a clear sign that your system has been infected. If your antivirus software and task manager are either crashing or disabled, a nasty virus has likely taken hold of your critical system files.
You may not be able to click on once-reliable apps. In the worst case scenario, ransomware may prevent you from opening favorite files.
You can try and fix the problem by booting your gadget in Safe Mode. With Safe Mode, your computer will be running with just the bare essentials. This way, you can safely delete and uninstall any programs and files that you can't during normal operation.
Windows:
On Windows, search for System Configuration then open it >> select Boot tab then tick off Safe Boot >>check Minimal (this is enough for most cases) >> click on OK to confirm >> Restart your computer.
Click here for detailed steps on how to boot into Windows Safe Mode.
macOS:
On a Mac, press and hold down the Shift key while restarting your computer. Keep holding the key through the Apple logo and release when you see the login screen.
Android:
Android also has its own version of Safe Mode but there are different ways to activate it, depending on your phone model. Click here to learn how.
iOS:
Stock iOS doesn't have a Safe Mode but you can try a soft reset to fix most issues. To do this, press and hold both your iPhone's Home button and the Sleep button at the same time, wait for it to restart then let go of the buttons when the Apple logo is displayed.
The iPhone X doesn't have a Home button so the process is a bit different. Press and quickly release the volume up button, press and quickly release the volume down button then press and hold the side button and release when the Apple logo appears.
5. You start seeing pop-up ads
Malware can also add bookmarks that you don't want, website shortcuts to your home screen that you didn't create, and spammy messages that entice you to click through. Apart from slowing down your gadget and eating away at your data, these intrusive notifications can also install more malware on your system.
Criminals can also use DNS hijacking to modify the ads that you see while browsing. Instead of the regular ads that you should be getting, they can be replaced with inappropriate or malicious ones.
On Windows, clean out adware with SpyBot Search & Destroy. On a Mac, use Malwarebytes for Mac.
6. Your gadget suddenly restarts
Automatic restarts are part of normal computer life. Software updates and new application installs can prompt you to reboot your computer. Your system will warn you when these happen, and you can delay or postpone them.
Yet sudden restarts are a different story. With Windows 10, there's a free malware detection and extraction program called Microsoft Windows Malicious Software Removal Tool.
I recommend a Full Scan with this tool to verify that your computer is updated with the latest malware definitions.
7. Unexplained online activity
See Who Is Hacking My Computer Mac 2017
Hackers covet your usernames and passwords. These details, coupled with social engineering tricks, can gain access to your banking accounts, your social media profiles, and your online services.
Keep an eye on your email's 'sent' folder and on your social network posts. If you notice emails and posts that you don't remember sending or posting, it's likely that you have been hacked.
Constantly check your accounts for unauthorized activity including movies on your Netflix profile that you don't remember streaming, mystery purchases that you haven't made, songs on your Spotify list that you didn't listen to, credit card charges that came from nowhere.
