“IoT Devices Beware: The BrickerBot”

Dear Blast Readers,

 

Do you leave your IoT (Internet of Things) Devices connected to the internet? Did you know that if you leave you IoT devices connected to the internet, even when you are not using them, it opens doors allowing hackers more time to gain control of your devices? Did you know that there is a form of malware that leaves your device impossible to use once infected?

 

A BrickerBot is a form of malware that has been created to infect a collection of devices. The “Bricker” in “BrickerBot” is referring to rendering a device, or devices, completely useless or inoperable, like a brick used as a paperweight. This is accomplished when the BrickerBot corrupts the device’s storage capabilities.

 

The way in which BrickerBots behave do not always match up with the behavior of traditional botnets. A botnet is a network of devices that have been infected. Their purpose is to keep the infected devices around for as long as possible.

 

Most botnets can be used for:

  • Sending out spam.
  • DDoS Attacks (also known as “Distributed Denial of Service Attacks”).
  • Phishing Attacks.

 

BrickerBot Malware uses a “Permanent Denial of Service” attack or PDDoS attack. This is when the BrickerBot physically disables the device.

 

How?

 

The device is physically disabled when the BrickerBot corrupts the firmware on the devices. Usually the only way to fix this is to replace the device, or if possible re-install the firmware.

 

BrickerBots use a set of commands to help accomplish their end goal of “Bricking” your smart devices. These commands will:

  • Render Flash storage useless by writing random bits to the storage drives on the devices.
  • Disabling TCP Time stamps, leaving connectivity vulnerable.
  • Limiting the processes that the devices can run at once.

 

How are you supposed to protect yourself from a BrickBot?

To protect yourself and your IoT Devices from BrickBots, you should:

  • Change your login information (BrickBots come with a dictionary containing default login information).
  • Limit the internet connectivity your device has. (Leaving your IoT devices connected, especially when you are not using them, gives hackers more time to take control and infect your devices.)
  • Install updates as frequently as they become available.

 

It is important to remember:

  • Every device that is smart and/or has internet connectivity should have STRONG PASSWORDS.
  • Take security into your own hands, do not rely on default security from the manufactures. (Remember: BrickBots come with a dictionary that contains default login information. Changing your login information should make your devices harder to hack.)

“Printers Beware”

Dear Blast Readers,

 

Did you know that 54% of employee’s say that they do not always follow the security policies put into place by their company’s Information Technology departments? * Did you know that about 51% of employees who have a printer, copier, or a multi functioning printer (MFP) at their work place say that they have copied, printed, and/or scanned confidential documents at work before? *

 

With cyber threats on the rise, it is not a shock that even printers are not safe from cyber attacks and data breaches. If a printer is connected to a wireless network and is unsecure, then it is open to hacking. Once compromised, other devices connected to the same network are left vulnerable.

 

How can a hacker gain access to a network using an unsecure printer?

 

One way a hacker can gain access to your unsecured printer is if the firmware is out-of-date. This allows the system to accept malicious lines of code. The hacker can then use the code to gain access to:

  • Print Jobs.
  • The user’s computer.

 

Another way a hacker can gain access to your unsecured printer is using a drone. Along with a drone the hacker would need a mobile phone and two applications. The two applications would do the following:

  • The first application identifies all wireless printers
  • The second application deploys malware into the printers.

 

So how does this type of drone attack occur?

 

Firstly, the hacker would fly a drone using a smart phone into position outside of an office building. Once into position, the hacker activates the two applications. Once the first application scans for open Wi-Fi printers, the second application establishes a fake access point (one that mimics the real device). Once established, the fake access point is then able to intercept documents that have been sent to the real device. With network access gained, the hacker can then in-bed malware into the company’s network.

 

When malware is installed within the network, hackers can gain access to your servers and documents by:

  • Accessing sensitive and/or confidential information.
  • Changing the printer’s settings or LCD readout.
  • Launching DoS attacks (Denial-of-service attacks).
  • Using the printer to receive and transmit faxes.
  • To send unauthorized print jobs.
  • Retrieving saved copies of documents.
  • Eavesdropping on network printer traffic.

 

To take preventative measures against attacks on your printers Some typical prevention procedures include, but are not imited to:

  • Educating Employees on the importance of security
  • Defining what constitutes a secure password
  • User identification (with PINs and other verification) for printer usage.
  • Data encryption protocols (to prevent interception of data across the network).

“In A Day Where Everything Is Getting Smarter, It Might Be Smarter To Play Dumb”

Dear Blast Readers,

 

Did you know that 6.6 million people in the US are stalked every year*? Only 1 in 5 victims are stalked by strangers*. 85% of stalking victims know who their stalkers are*. Did you know that there are 78% of stalkers use more than 1 approach when it comes to stalking their victims*?

 

We live in a day and age where technology is continuing to get smarter. With technology getting smarter so are the cyber criminals. Today Cyber criminals are always looking for vulnerabilities and back doors to provide access to his or her next victim.

 

Recently, vulnerabilities in cyber security have been found hiding and lurking in the shadows of smart appliances. Some examples of smart appliances include:

  • Smart Refrigerators
  • Smart Slow Cookers
  • Smart Dish Plates

 

Smart Refrigerators can have 3 built in cameras, that allow you to see inside of the Refrigerators from where ever you are. They also can have the capability of streaming music, streaming videos, as well as sharing calendars, notes, memos and pictures. The Smart Refrigerators can also have voice activated features. If these refrigerators fell victim to a hack attack, then hackers would have total control over all the features.

 

By hacking the Smart Refrigerators, hackers can then peer into your life. Watching you, your spouse, and even your children with the help of the video feed that comes from the Smart Refrigerators cameras.

 

Also, they can listen to every conversation going on inside your home because of the voice activation speakers (the speakers that help to refrigerator listen and respond to your commands).

 

The Smart Refrigerators can also share calendars, notes, memos and pictures. If a hacker was to gain access to this information, it could be sold on the dark net to someone with malicious intent. But, you could also be stalked. With this information, a stalker would know your schedule, know what your family and friends look like, where your favorite places are, among other things.

 

A Smart Slow Cooker is another smart device that cyber criminals and/or hackers could use to their malicious advantages. Being a Bluetooth connected device allows the Smart Slow Cooker to connect to smartphones (both Android and iOS devices), and tablets that have the Smart Slow Cookers application. From this application, you can control all the features, including:

  • Adjusting the temperature
  • Turning the Smart Slow Cooker on/off

 

With access to the Smart Slow Cookers, hackers would be able to get into the application and mess with the settings. They would be able to turn it on and off as they pleased, they would also be able to control the heat settings, possibly being able to blow the power source creating a fire. Hackers would be able to do all of this without the consent or knowledge of the device’s owners.

 

Do you wear a fitness tracker on your wrist consistently? Do you monitor your caloric intake with said device? Did you know there is a Smart Dish Plate that can help you track your eating habits and calorie intake? The Smart Dish Plate is Bluetooth and Wi-Fi connected. It connects to your smartphone, via application, and your fitness tracker. It also has 3-mini built in cameras.

 

If hackers and/or cyber criminals were to gain control over this device, then it is likely that your phone and its data will be targeted as well. This leads to the possibly that this data could be sold on the dark net.

 

With the 3-mini built in cameras, hackers would also be able to spy on you through the camera feed.

 

By gaining access to the smart kitchen appliances, hackers can do many things without your knowledge or consent. They can control the device and all its features and they can also gain access to any other internet connected device connected the same network, including:

  • Smartphones
  • Tablets
  • Computers
  • Alarm systems

“Beware of the Facebook Notification Virus”

Dear Blast Readers,

 

You are on your Facebook account, answering messages, liking posts, watching videos, and commenting on your friend’s photos. Suddenly, you receive a message from your friend Sam. The message contains a link to a funny cat video in which a cat in a hat is dancing with a maraca in its mouth. The message below the video says “Hilarious video. You NEED to check it out!”. Without giving it a second thought you click on the link to view the video. But, instead of viewing the video you get redirected to a site that you don’t recognize or trust. Naturally, you exit out of the browser thinking that maybe Sam has attached the wrong URL. But, it is too late. Your device has already been infected.

 

Security experts have identified a form of adware that targets social media users tricking them into infecting their own devices. It is known as the “Facebook Notification Virus”. This virus displays messages saying that they are from Facebook. The “Facebook Notification Virus” creates many different forms of messages, including:

  • Friend Requests
  • Chat Messages

 

Some of the notifications that the user received are real copies of notifications that users would see on the real social media site (making the fake notifications seem legit). While other notifications are presenting new features. The purpose of this adware is to redirect users to specific websites, most likely malicious websites, so that the user’s device becomes infected with malicious software. This virus does not just lead users to malicious websites, it also:

  • Monitors User Activity
  • Collects User Information
  • Records Browsing History
  • Tracks Cookies
  • Tracks Keystrokes
  • Tracks IP Addresses
  • Tracks Geographic Location
  • Tracks Zip Codes
  • Tracks Demographic Profiles
  • Tracks Emails
  • Tracks Telephone Numbers
  • Tracks Usernames
  • Tracks Passwords

 

After all this information is collected, the collector, hacker, will then attempt to sell your confidential information on Darknet Markets, then falling into the hands of much more malicious cyber criminals.

 

So, how does this virus spread?

 

The “Facebook Notification Virus” can be spread a few different ways, including:

  • Freeware
  • Shareware
  • Pirated copies of paid utilities.

 

Another way that it can spread is through spam emails. The sender of the spam emails wants you to open the so that his or her tool can get inside your system and infect it.

 

To protect your data and system from the “Facebook Notification Virus”, if you receive any suspicious messages from “Facebook”, you should:

  • Check your system, because you may have been infected.
  • Be careful of the software that you allow in your machine.
  • Verify the email addresses of the “companies” that have messaged you (visit the contact page on the official website of the “company” to verify the email address).

“Television: A Hackers Window Into Your Home

Dear Blast Readers,

 

It has happened. Your home has been invaded. The one place you thought that you were safe from anything malicious has been breached, and it is because of your smart TV. Smart TVs, being one of the most popular devices, present new security risks for users.

 

Hackers can gain access to your home through your TV, and they wouldn’t even need physical access to do so. The only thing that they would need is a “Low-Cost Transmitter”.  A “Low-Cost Transmitter” can easily be purchased online through third party vendors such as Amazon or EBay.

 

With this device, a hacker would be able to send radio signals that can be picked up by your Smart TV and any others within range of the transmitter. When the TV picks up the signal, the hacker has complete and total control of that TV. This then allows the hacker to get privileged access to the TV. Once access is gained, the hacker can cause chaos and harm in many ways, including:

  • The hacker could spy on you through the TVs camera and speaker.
  • The hacker could attack your other Internet connected devices such as: Computers, Tablets and Smartphones.
  • Hackers can access your stored credentials and personal data, putting your identity at risk.

 

Typically, infections are in the temporary memory. The steps to secure your devices varies from product-to-product. Some ways to protect yourself and your data include:

  1. Restart your device regularly.
  2. Secure your router.
  3. Be smart with your web-connected devices.
  4. Check firmware updates (manually if it does not automatically check for updates).
  5. Be vigilant for irregular activity occurring on your network.
  6. Place a piece of tape over your TV’s camera for a low-tech way to ensure privacy.
