What makes a Film Great?

One may wonder- what makes a movie great? Is it just the presence of a top-named actor or actress? Is it the great characters in the film? Well you might land in with interesting responses. But the answer is, Yes, it requires ALL of these. Making a film is itself a big undertaking. It requires all factors, be it technical or non-technical, to a great film. From the artist’s acting skill to director’s cast selection and guidance, from soundtracks and lightings to Visual Effects, all have special need in the success of a film. In this article, we will dive into the top factors to a successful film.

Here are the top 7 factors of successful films:-

  1. Script
  2. Cast
  3. Acting
  4. Character
  5. Director
  6. Visual Effects
  7. The Message

Lets dive into details of the factors of a successful Film.


Script of the film is the soul of a successful film. A Script tells the complete story of the film. It includes story, dialogues, action sequences etc. A film may not have big-name actors in it, but a great script or story can make the film a Blockbuster. The quality of the script really makes wonderful films. A truly amazing script captures the attention and interests of the audiences. This is great in word-of-mouth promotion of the film, which is better than rest of marketing methods.


The cast is an important factor in the success of a film. A Casting Director visualizes the screenplay and chooses the best possible talents for the roles. Then he present these options to the Director of the film. A Director makes the final decision keeping in mind the need of the script. The chemistry between the casts can make the film a blockbuster.


Acting is an activity in which an artists enacts a particular character. The character he interprets could be real or fictional. An actor’s priority is to effectively interpret the character that they are playing. Actors need to communicate to the audience through his voice, emotions, actions, body language. Acting of an actor must be such that they convince people to think about the character he is playing.


Character of the film is one of the key factor to a successful film. It is the portrayal of character that hits into subconscious mind of people. Hollywood Superhero characters like Iron-Man, Thor, Thanos, Shang-Chi need no introduction to the audience. Disney cartoon characters like Tom & Jerry, Scooby-Doo, Donald Duck are clearly fed into people’s mind. Even one can recall the character of James Bond, Will Smith’s character in MIB.


A director is someone who guides the actors and crews in the fulfilment of a vision. It is the prime duty of director to visualize the script and casts artists into the characters. Definitely a great director can make a film blockbuster. A great director always creates a credibility among the audience.

Visual Effects

Visual Effects in the film are a way to keep the audience glued to the screen. Now, the VFX and advance film editing Softwares & Applications has made it easy for the editors to create a WOW visual effect. VFX is nothing but the manipulation of any on-screen imagination of a character that does not exist physically in this real world. These visual effects of VFX allows the filmmakers to create objects, environments, creatures that would be otherwise impractical in the real world. Who would forget the visuals from Avengers, Gulliver’s Travels, The Tomorrow War? Visuals are basically a medium to be creative in imagination. This keeps the audience bind to the film.

The Message

What makes a film great is the message that movie is trying to convey to the people. Over and above all, it must be the prime goal of a film. A meaningful movie is always appreciated. Though a film needs a mix of entertainment, fantasy, thrill, action but a film must stick to a message.


A film is the visualization of a Screenplay writer. For a successful film making gross box office collection needs a mix of several factors. It includes Story of th film, Acting, Cast& Crew, Great directors.

Bluetooth Attacks – How to Secure Mobile Devices against Bluetooth BIAS attacks


  • Attacker gains access to target device over Bluetooth connection
  • Devices not updated after December 2019 are vulnerable
  • Turn OFF your phone’s Bluetooth

Bluetooth Definition

What is Bluetooth?
Bluetooth is a wireless technology that powers wireless communication. It connects your phone to other electronic devices through Internet of Things (IoT). A Bluetooth connection involves connection between a host and a client device.

The term “Bluetooth” is coined after the Viking king, Harald Bluetooth Gormsson. This is due to his work to unite different 10th-century European factions.

Bluetooth is simple & productive in file sharing, but has major security risks. While most of the bugs have been fixed a decade ago, some still remain.

Even the new smartphones have yet-undiscovered problems.

Bluetooth Impersonation AttackS or BIAS

What is BIAS?
Bluetooth Impersonation AttackS (BIAS) is a vulnerability in which the attacker impersonates the secret key or address and connect to a Bluetooth device without any authentication.

BIAS vulnerability is usually found in the Bluetooth Classic devices.

These follows the Bluetooth Basic Rate Extended Data Rate (BR/EDR) wireless technology. This technology is the standard for a wireless personal area network (PAN).

Bluetooth Impersonation AttackS comes into picture while configuring Bluetooth Devices for the first time.

When two devices are paired for the first time, a key or address is generated. This secret key works as Authentication and allows Bluetooth connections between the two devices to be seamless.

The Bluetooth Standard provides security features to protect against any eavesdropping, manipulation of information, malicious file download etc.

Despite these security features, a BIAS attack can impersonate the key or address, and connect to a device without the need of authentication.

Since it appears as if it had been previously paired, it do not require further cross check. This makes the devices prone to eavesdropping and Data manipulation.

In addition, the researchers Daniele Antonioli, Kasper Rasmussen, and Nils Ole Tippenhauer have noted that the attack is standard compliant.

This means that any standard-compliant Bluetooth devices are vulnerable to this attack.

Bluetooth vulnerability

Is Bluetooth technology vulnerable?
“Bluetooth technology is dying out”, the narration comes out more often. But this is far from the truth.

There are billions of devices in the world that use the Bluetooth technology. Big Data, Hadoop, Cloud Technologies etc have helped technogiants modernize their offerings.

Though WiFi is gradually replacing Bluetooth to transfer files, people still use Bluetooth with their headsets, speakers, and other devices.

Since Bluetooth allows an automatic wireless connection, it leaves data vulnerable to interception. Connecting devices over Bluetooth encourages High Security Risks.

The research team discovered a critical bug in Android’s Bluetooth implementation. The Bug allowed remote code execution without User interaction.

The testing included smartphones from manufacturers like Apple, Google, Nokia, Samsung; laptops from HP, Apple MacBook; headphones from Philips.

Researchers tried a BIAS attack on 31 Bluetooth devices with 28 unique Bluetooth chips from Intel, Apple, Qualcomm, Samsung, Cypress, CSR, Broadcom, and others.

All the sample devices were vulnerable to the BIAS attack.

Who could hack your phone?

  • Government spies
  • Politician
  • National Security agencies
  • Business rivals
  • Spouse
  • Employer

Bluetooth Guidelines by SIG

What are the major Guidelines by SIG to prevent Bluetooth attacks?
The researchers found the vulnerability in December 2019.

They informed the Bluetooth Special Interest Group (Bluetooth SIG).

SIG is the standards organization that oversees Bluetooth protocols.

According to Special Interest Group – “a Bluetooth bug puts User’s phone prone to high end security risks. Any Bluetooth standard compliant devices have this vulnerability”.

Bluetooth SIG directed the manufacturers to fix the Bugs. SIG recommended that users get the latest updates for their devices.

In light of these directions, Google rolled out an update to the bug.

Common Bluetooth Security Problems

(01). Blueborne

Blueborne is a data vector that invades users’ devices via Bluetooth. It can infect Android, iOS, Windows, Linux devices.

The Palo Alto-based cybersecurity firm Armis confirms that the Blueborne is spread through the air.

It can recognize the vulnerabilities in the system and use them against the target device.

Blueborne targets the weakest spot. Blueborne can penetrate into computers, smartphones, tablets, televisions, remote controls etc.

What makes Blueborne Dangerous?

The Dangerous conern about Blueborne is that the two devices does not require to be paired together to launch an assault.

Attackers can even target the devices that are not in Discovery mode.

New machine learning tools have helped them learn to penetrate security more easily than ever.

They are then able to take complete control over the device and access any data stored within.

(02). Bluejacking

The bluejacking refers to sending a message to a nearby Bluetooth user.

Bluejacking messages includes text, images, sounds etc.

If targeted, your smartphone then adds the sender to the address book as a contact.

The hacker can use this position to send harmful messages that open automatically on your screen.

Bluejacking is relatively harmless but is vey annoying. It causes some confusions when users start receiving messages.

(03). Bluebugging

Bluebugging attacks allow a Hacker to take full accessibility and control of the target mobile phone.

This is possible when its Bluetooth is in Turn On mode.

This attack takes over control of mobile phone to make calls, send texts, read messages.

Attackers use a variety of data mining tools to make this possible. These messages encourage the recipient to take some action. This leads to further data exploitation.

What makes Bluebugging Dangerous?

The main Dangerous concern about Bluebugging is that the real owner of the device doesn’t even know that their number is being used to send those texts.

The real owner cannot even warn the recipient to ignore the content they receive.

(04). Bluesnarfing

Bluesnarfing refers to the stealing of data through unauthorized access via Bluetooth.

Combining the methods of Bluebugging and Bluesnarfing are a deadly combination to enter a user’s device via Bluetooth.

Bluesnarfing Attackers can steal data such as call information, text messages, email, passwords, contacts etc.

Attackers use tools like obexftp, hcitool etc.

Bluetooth attacks : Signs your phone may have been hacked

How we can say my Bluetooth device is under attack?

(01). Draining battery life

A smartphone that has been compromised starts to deplete phone’s lifespan drastically.

This is because the Spy App uses phone resources to scan the device. It then, transmits the information back to the Hacker’s server.

(02). High data usage

When your device is under attack, Spy Apps running in the background, sends information back to the Hacker’s server.

This process requires internet connection and data usage.

If your device is under attack, you get high data bill.

(03). Sluggish performance

A device under attack starts to overload the phone’s resources.

It leads to two applications clashing, over phone’s resources usage.

Frequent freezing, certain applications crashing are the signs of your device being hacked.

Sometimes it happens, despite our efforts to close, some applications runs continuously, beware your device may be under attack.

(04). High phone bills

The attacker can use your phone to contact someone, you don’t even know. Make sure to analyse your phone bill, for any costs you don’t recognize.

(05). Pop-up Alerts

A constant pop-up alerts could indicate that your phone has been infected with some Adware.

Adware is a form of malware that forces devices to view certain specific pages that drive revenue through clicks.

Many pop-ups are phishing links that attempt to get users to type-in sensitive information.

It may also encourage to download more malwares into your system.

(06). Unusual Account Activity

If your phone is under attack, hacker have access to phone’s accounts. These accounts may include your social media Login credentials, email etc.

Now, one may guess, upto what extent Hacker can exploit your confidential information. In this case, you could be at risk for identity fraud.

So, it’s a good idea to frequently change your passwords, something hard to guess.

How to Reduce Bluetooth Security Risks?

(a).Turn Off Bluetooth when Not in Use
When a device is in Visible or Discovery mode for a longer time, it has higher chances of Bluetooth Security risks.
Make sure to turn off Bluetooth, when not in use. It helps to minimize the risk of an attack.

(b). Regular Update
Updates carry important bug fixes and solutions. Regular device update can prevent security risks.

Use the latest version of Bluetooth and make sure the Operating System is up to date.

(c). Use a VPN
A Virtual Private Network or simply VPN, helps to encrypt your data and secure the device. A VPN increases the security levels of your device.

A VPN allows to browse the internet anonymously, thus prevents the attacker of getting your phone’s access.

Select a VPN that offers a strong encryption protocol with plenty of server locations.

(d). Trusted Pairing
When using Bluetooth, only pair your phone with devices that you are familiar with.

Make sure the other device is also using the latest version of Bluetooth updates. It will reduce the risk of data interception and security risks.


What are the major steps to prevent devices from Bluetooth attack?
Tips to secure your mobile devices from Bluetooth attacks or BIAS attacks.

  1. Threat : Bluetooth Discovery Mode
    While pairing two devices, Bluetooth uses MAC addresses for first time configuration. This is done under Discovery Mode. This is the interval for a possible attack by a potential Hacker.
    Attackers can eavesdrop on your conversations, by exploiting these vulnerabilities.

Solution : Switch Off Bluetooth when not in use.
Use Hidden mode as much possible.
When you enable Bluetooth, make sure it is in Hidden mode. This does not disconnect your Bluetooth devices. The Hidden mode prevents Bluetooth devices from recognizing your device. This prevents possible Bluetooth attacks.

  1. Threat : Eavesdropping
    Eavesdropping should not be a problem in any communication. However, older Bluetooth devices face the threat of unpatched security holes. The device becomes a medium of transmitting everything it hears to an attacker.

Bluetooth Encryption helps to Stop criminals listening in to your phone calls.

Solution : Ban devices that use Bluetooth 1.x, 2.0, 4.0-LE.
Use latest Bluetooth versions.

  1. Threat : Software vulnerabilities
    Software installed in Bluetooth devices are security vulnerable.

In 2011, Reasearchers demonstrated that it’s easy for attackers to discover new Bluetooth devices, with some security loop holes. Potential impacts could include data stealing, huge ransom demands etc.

Solution : Switch off Bluetooth when not in use

  1. Threat : Bluetooth range
    Harald “Bluetooth” Gormsson designed Bluetooth for Personal Area Network. PAN ensures devices that are away from Bluetooth Range, should not be accessible via Bluetooth. A typical Bluetooth has a range of around 10 feets.

However, Attackers use directional, high-gain antennas to communicate over much greater distances successfully.
Security researcher Joshua Wright demonstrated the use of Directional, High-Gain Antenna to hack a Bluetooth device in a Starbucks from across the street.
