What is Ransomware? How to protect your PC from ransomware attacks?


You return home from the office, turn on your computer, here it is- a tormenting message informing you that the data on your computer system is encrypted. The only way to unblock it is to pay the ransom. You have been hit by a Ransomware.

Let us know something about “ransomware”?

Ransomware is a modern day abduction technique where the victim is barred from the system access and a ransom is demanded in order to restore data. The user is generally notified regarding the exploitation and even the instructions are provided to recover the files. The malware restricts access to computer data and demands a ransom in exchange to lift the block. The attack may also display fraudulent error messages.

The main motive of implementing ransomware by the cyber criminals is strictly monetary and unlike the other malicious software, the victim is informed about the exploitation. The idea is not what the data is worth to someone else rather how much someone can pay to ransom it.

It blocks the victims’ computer usage either by encrypting certain part of the hard drive or displaying a message that the system has been locked. Once the files are infected, which may be for whatever reason but can only be recovered after the certain ransom is paid. The ransoms paid are demanded electronically through virtual cash so as to hide the identity.

Ransomware kits on the internet are readily available which had allowed the cybercriminals to easily launch an attack with minimum or no technical background by purchasing the inexpensive ransomware-as-a-service (RaaS) programs.

How ransomware inflicts the system?

The ransomware can be spread through e-mail attachments, infected storage devices, unauthorized and compromised websites and infected software applications.

The malicious software may manipulate the victim’s user credentials for the computation of the device and in data kidnapping attack the malware may encrypt files located on the storage devices as well as connected networking devices.

Modus Operandi

The ransomware attacks are generally carried out by a Trojan, entering the computer system through any downloaded file or a pitfall on a bad network. The program then runs the payload thus exempting user access in some fashion. Some of the payloads may contain only an application which is designed to lock the system until the ransom is paid.

It is a three-way protocol:

  1. The attacker releases the malware by generating a key pair and puts the corresponding public key in the malware.
  2. The malware encrypts the victims’ data by generating a random symmetric cipher text. It implements hybrid encryption technique to encrypt the files where a public key is used so as to encrypt the symmetric cipher text. It replaces the victims’ symmetric ciphertext by an asymmetric ciphertext and nullifies the symmetric key and the original cipher. It then displays the message containing the asymmetric ciphertext and way to pay up the ransom.
  3. After the victim sends the asymmetric key and the virtual money to the attacker, then attacker decrypts the asymmetric ciphertext employing the attackers’ private key. The attacker sends the symmetric key to the victim where the user can decipher the encrypted data.

This completes the cryptology procedure.

 Types of ransomware

  • Lock screen Ransomware: It deprives the user access to the computer device.
  • Encryption Ransomware: It manipulates the files contained in the device.
  • Master boot record Ransomware: It manipulates the master boot record.
  • Ransomware encrypting web servers: It encrypts the web servers threatening to post certain information publicly.
  • Android mobile device Ransomware: It is installed as a .apk and can display block message on all applications.
  • IoT Ransomware


  • The Windows operating system should be upgraded regularly so as to curb the threat of ransomware threats.
  • Data should be backed up to an external hard drive.
  • Turning off of the Remote Desktop feature minimizes the threat of ransomware.
  • Antivirus should be genuine and should be updated regularly.
  • Avoid using malicious or unauthorized websites.
  • Enable the system protection or file history.
  • Scan the email attachments before downloading.
  • Always use a password protected internet connection.
  • Disable macros in the Microsoft Office programs.

About Olympus TG-870

Olympus TG-870 is shockproof from 7 feet, waterproof down to 50 feet, dustproof, freezer proof down to 14° F, crushproof up to 220 pounds: to its predecessor it has identical ratings. Same ultra wide 21-105 mm is kept by the Olympus that is equivalent to 5x zoom lens with aperture range of f/3.5-5.7 at the max, in order to reduce blur due to camera shake, the optical image stabilization system is designed. The lens is16-megapixel, backside-illuminated CMOS image sensor, 1/2.3-inch type, with a TruePic VII-branded processor; as in the Olympus TG-860 the setup is same.

ZPR-OLYMPUS-TG870-BLK-BEAUTYUp to 7 frames-per-second the TG-870 can shoot with its predecessor at full resolution, but only seven-image buffer is provided. If reducing of capture rate to 2.5 frames-per-second is possible then buffer size can be increased to 200 images. In order to have faster speed then both 20 and 60 fps can be shot for up to 60 frames, but in size the resulting images will be only 3 megapixels.

An exposure mode dial setting includes Program Auto, Intelligent Auto, Scene, Sportscam, Art Filter, Super Macro, Self Portrait and Panorama, as on the TG-860 it is same.

The scene modes includes e-Portrait, Portrait, Live Composite, Interval Shooting, Landscape, Night Scene, Hand-held Starlight, Sport, Night + Portrait, Fireworks, Sunset, Documents, Cuisine and Beach & Snow, Under Water Wide1, Under Water Snapshot, Under Water Macro, Under Water Wide1 and Backlight HDR.

The TG-860’s seven Art Filters explains the Olympus TG-870 by adding six new ones: Key Line, Vintage, Light Tone, Watercolor, Gentle Sepia and Cross Process to the existing Soft Focus, Pop Art, Grainy Film, Pale & Light Color, Diorama, Pin Hole and Dramatic Tone filters.

As mentioned previously, dedicated Sportcam position is retained by the TG-870 on the mode dial introduced in the TG-860 that enables easy and fast access to High-Speed Movie, Full HD 60p Movie, Sport Burst modes and Time Lapse Movie and provides options that are similar to those who are offered by popular action cams.

In the next generation it is expected that the TG-870’s GPS is faster to synchronize when compared to TG-860, that to under 10 seconds for three satellites. Users of the Olympus Image Track (OI Track) app are allowed to update the TG-870’s GPS assist data and also can transfer GPS images and logs from the camera to your mobile device.

Safe and Secure Syncing – BitTorrent Syncing

BitTorrent Sync


Why BitTorrent is Special for Syncing?

Cloud Services are plenty in number and all are awesome in working of it as every application gives their best to the users for the storage and when you talk about the Dropbox, Cloud service app which is much useful for the different users who uses the cloud application. But in real case these services cannot gives much control of it as it is programmed in such a way.

DropBox, Google Drive and Box are the different applications, but here there is an application name as BitTorrent which is a safe and secure cloud service for storing data as this service is the only service which provides you security for the stored data and also you can get control of it.

Get Control of Syncing with BitTorrent Sync:

If you are willing to get control without making lose of features of the cloud service, then I recommend you to select the BitTorrent app for syncing as it is program in such a way that it gives you control over it unlike the others.

BitTorrent Sync – Design Simply and Easy to Use:

You may get an idea to make use of it anyway but some of you may get worried about how to make use of it. Here you should know about the fact that it is much simple and easy to make use of it as it is not designed so complicatedly. Even though you are new users to it, you may not feel much difficult as it more probably works same as the other cloud services do.


BitTorrent Sync vs. DropBox:

DropBox and the other cloud services are mostly expensive when you compared it with the BitTorrent Sync service as this will get you in low price. As the features increases in the app, simultaneously the price also increases but the BitTorrent instead these many features, it won’t cost high and you can get at reasonable price.

Security is much needed in each and every field, but when you come to this sync services, it is very much needed to have security of data so BitTorrent Sync provides you the secure of the data as there are much chances of hacking the data by the hackers in the field of this, so there is much needed to make use of this safe technique instead of other so that you can protect your data from the others. The more advantages of BitTorrent over DropBox are listed below.

  • It is free online cloud service
  • Storage space is limited on your HDD
  • It has high fast transfer rate of data
  • No more effect of server downtime
  • Easy to sync any folder or file from any place of HDD

How SSD Hard Drive Works?

SSD or Solid State Drive is a solid state storage device that uses integrated circuit. SSD primarily uses electronic interfaces which is compatible with input output hard disk drives. The main reason which distinguishes SSD from other traditional disk such as hard disk drives or floppy disk are its non-moving components. The data is electronically moved in SSD whereas in other hard drives spinning platter and placement of the actuator arm helps in moving data.

The Solid State Drive uses a type of memory called Flash memory. This Flash memory is almost similar like RAM. However, unlike RAM, which clears whenever the computer powers down, SSD memory remains even when it loses power. If you were to take apart a typical hard disk, you’d see a stack of magnetic plates on an axis with a reading needle–kind of like a vinyl record player. Before the needle can read or write to the plate, it has to spin around to the right location.

SSDs, on the other hand, use a grid of electrical cells to quickly send and receive data. These grids are separated into sections called “pages,” and these pages are where the data is stored.

How do SSDs Work?

One big problem of SSDs is inherent in flash memory itself: it can only sustain a finite number of writes before it dies. There is a lot of science that goes into explaining why this happens, but suffice it to say that as the SSD is used, the electrical charges within cells must be periodically reset.

But at the end of it all, the SSD does offer something that a traditional HDD could never bring: lightning-fast speeds. The SSD is an intricate creation that has many layers of complexity behind it, and while it does come with a number of its own disadvantages, it certainly does its job well. It should be obvious by now that SSDs require much more sophisticated control mechanisms than hard drives do. That’s not to disc magnetic media — it actually HDDs that deserve more respect than they are given.

The mechanical challenges involved in balancing multiple read-write heads nanometres above platters that spin at 5,400 to 10,000 RPM are nothing to sneeze at. The fact that HDDs perform this challenge while pioneering new methods of recording to magnetic media and eventually wind up selling drives at 3-5 cents per gigabyte is simply incredible.

How to Resolve Wireless Connection Problems?

Most of the PC users are facing the problem of wireless connection in their systems. If your PC has a wireless network adaptor, then you will see a wireless icon in the system when you click on the Setting options. Windows automatically detects the wireless networks that are in range. To see the available list of wireless network move the pointer to the upper right corner of the screen. Now move the mouse pointer down and then click on the settings options. Now click on the wireless network icon which is shown on the screen. If your Windows systems fail to detect the wireless network it means that the network is not within the range of your PC. There are so many reasons behind this. Unless your system detects the wireless network you are not able to use the internet.

Let us discuss some of the problems due to which wireless network problem arises:

  • Check whether the wireless switch on your PC is turned on or not. If it is turn off state then turn it on.
  • If your system Airplane mode is turned on then you are not able to connect to the wireless network. To turn off the Airplane mode go to the right edge of the screen and the click on the Settings option. Now click on the wireless network icon and make sure that Airplane mode is turned off or not.
  • If your PC is far away from the wireless router or access point, then move your PC close to the access pointer. If you are not able to move your PC then install an external antenna for your wireless adaptor to improve its reception.
  • If your wireless router or access point is turned off or not working properly then you may face the network problems. Make sure that your wireless router is turned on and the wireless signal light is on.
  • If the wireless router or access point are busy then will not respond to new requests. If they are several PC’s or devices or if you have another PC which is connected to the network, try temporarily by disconnecting them.
  • If the network you are searching is not set to broadcast its network name, then you may face wireless network problems.
  • If you are in corporate network, then the network admin has the right to control the wireless networks. If your wireless network is not within range of your PC that means your network admin has blocked the network. In such cases you can contact him.
  • If you are running network monitoring application on your PC, then the wireless adapter will be set to monitor mode which prevents the Windows from connecting to the wireless networks. To connect to the wireless network close the network monitoring app.
