what is deepfakes in AI

Ever wondered why your cybersecurity team keeps talking about deepfakes lately? We live in a world where a simple video of your CEO could cost your company millions – except it wasn’t really your CEO at all. Deepfakes have transformed from a quirky internet trend into a serious business threat, costing organisations billions in fraud. When 1 in 10 executives have faced deepfake threats, we’re not just talking about sci-fi scenarios anymore. We’re talking about real businesses, actual losses, and real reputational damage happening right now.

Running a business is already tough enough without AI-generated imposters faking announcements or sending deceptive messages to your team. But here’s something worth noting: while deepfake technology is becoming more sophisticated, we’re also getting better at fighting back.

In this guide, we’ll break down everything your business needs to know about deepfakes – what they are, how they work, and most importantly, how to protect your organisation from becoming another statistic in the growing list of deepfake fraud victims.

What is Deepfakes?

Deepfakes are synthetic media generated by artificial intelligence (AI) and machine learning algorithms, primarily using Generative Adversarial Networks (GANs). They use AI techniques for the creation of hyper-realistic images or videos, audio, and text that appear genuine but are entirely fabricated. The term “deepfake” comes from the combination of “deep learning” and “fake,” and it reflects the ability of AI to manipulate reality in disturbing ways.

Deepfakes can create convincing video or audio clips of people saying things they never actually said, doing things they never actually did, or appearing in contexts they were never part of. The use of deepfake technology has rapidly evolved, and the implications for individuals and businesses have become clear: deepfakes represent a serious cybersecurity threat that can undermine trust, facilitate fraud, and damage reputations.

How do Deepfakes Work?

At the heart of deepfake creation is the use of AI techniques. This generative AI may sound complex, but it’s essentially an intelligent system made up of two neural networks: a generator and a discriminator. The generator creates synthetic media—videos, images, or audio—while the discriminator evaluates its authenticity.

Through continuous learning, the AI refines its forgeries, making them increasingly realistic. By analysing vast amounts of data, such as photos, videos, or voice recordings, deepfake technology can replicate a person’s appearance, voice, and mannerisms with startling accuracy. This enables the creation of videos or audio clips that appear genuine, making deepfakes a powerful yet dangerous tool for misinformation, fraud, and deception.

How Deepfake is Made?

Using deepfake is more straightforward than many people think. Several user-friendly apps and AI technologies have emerged that allow anyone to use deepfake technology to impersonate someone with just a few clicks. Here are some examples:

  1. FaceApp: FaceApp is an app that transforms photos to add or remove features. Users can create celebrity-like pictures, aging effects, and more. While it’s fun for personal use, it shows how easy it is to manipulate images.
  2. Wombo: Wombo allows users to create singing and dancing video clips from their uploaded photos. The app uses AI to animate still images and make them appear to sing popular songs. While it’s mostly harmless, it demonstrates the potential for deepfake creation.
  3. Deepfakes Web: Deepfakes Web is a cloud-based application that allows users to swap faces in videos. It’s a more advanced tool, enabling highly realistic video manipulations.
  4. Face Swap Live: Face Swap Live lets users swap faces with someone during live videos or with figures in images. It works in real-time, offering a more interactive experience, but it also opens doors to potential misuse.

Deepfakes are evolving—so should your defences. Contact Binary IT now for cutting-edge detection systems, employee training, and strong authentication protocols to keep your business secure.

Types of Deepfake Frauds: What You Need to Know

Deepfake content can take various forms, each with its potential for harm. Let’s break down the most common types of deepfake frauds:

1. Textual Deepfakes

You might be thinking, “A deepfake is all about images and videos, right?” Well, not always. Textual deepfakes refer to AI-generated written content that mimics a person’s unique writing style, tone or voice.

AI tools can analyse past communications and recreate emails, messages, or even entire articles in the exact style of the person being impersonated. This type of deepfake is often used in phishing and social engineering attacks or business email compromise (BEC) attacks, where fraudsters attempt to trick recipients into taking actions they wouldn’t usually take, like sharing sensitive information or authorising financial transactions.

2. Deepfake Video

Deepfake videos are what most people think of when they hear the term “deepfake.” These involve altering or completely swapping out someone’s face, voice, or body in a video, making it appear as though they are doing or saying something they never did. This could range from a fake political speech to a fabricated business deal involving your CEO.

Cybercriminals can create a deepfake video to spread misinformation, damage reputations, or even blackmail individuals. In a corporate context, deepfake videos can impersonate employees, leading to the unauthorised disclosure of confidential information or approval of fraudulent transactions. The best defence against this kind of deepfake is being able to recognise the signs and verify the authenticity of the content.

3. Deepfake Audio

Deepfake audio works the same way as deepfake video, but with a twist—it manipulates voice recordings. Using deep learning, AI can clone a person’s voice with startling accuracy, making it sound as though they’re saying things they’ve never actually said.  Deepfake audio is often used for voice phishing (also known as vishing) attacks, where fraudsters manipulate audio to impersonate a trusted person and deceive victims into sharing sensitive information or authorising actions.

Deepfake audio can also be used to create fake interviews or fake conversations, leading to severe reputational damage for public figures or organisations. It’s an increasingly common fraud tactic that requires strong verification systems to defend against.

4. Deepfakes on Social Media

Social media platforms are a prime breeding ground for deepfakes. Fake videos, images, and audio clips can spread quickly, causing widespread misinformation or harming the reputation of individuals and businesses.

On social media, deepfakes can be used to create fake news stories, alter political speeches, or impersonate influencers and celebrities. Because social media succeeds in rapid sharing, these deepfakes can quickly go viral, causing real-world consequences. This type of fraud is particularly damaging because it capitalises on the trust users place in digital media and can influence public opinion or market behaviour.

Don’t wait until it’s too late. Contact Binary IT now to implement strong measures against deepfake threats and keep your business one step ahead of cybercriminals.

5. Real-time or Live Deepfakes

Real-time or live deepfakes are among the most disturbing forms of deepfake fraud. Using software that manipulates video streams in real time, attackers can swap faces or alter voices during live interactions. This is often used in video calls or live broadcasts to impersonate someone in real-time.

What Are the Ways to Detect Deepfakes?

Facial Anomalies

One of the easiest ways to spot a deepfake is by examining the face for irregularities. These might include uneven blinking, unnatural facial expressions, or exaggerated movements. You may also notice distorted facial features, like misaligned eyes or uneven lips. Additionally, blurry or pixelated areas around the face often indicate manipulation. Missing or inconsistent facial details, such as moles or wrinkles, are another telltale sign of a deepfake. Paying close attention to the face can often reveal subtle imperfections that expose a fake.

Movement Inconsistencies

Deepfakes struggle with natural movement, so look out for inconsistencies. This includes poor lip synchronisation with the audio, where the speaker’s lips don’t quite match the words they’re saying. Unnatural head movements or body posture that doesn’t flow with the rest of the video can also be a red flag. Jagged or jerky motions, especially when the person is moving quickly, can indicate that something has been altered. If facial expressions seem inconsistent or out of place, it could also signal a deepfake, as AI often fails to replicate natural emotional changes.

Background Issues

Deepfakes sometimes have trouble replicating a consistent background. You might find blurred or distorted details behind the subject, which can be a sign that the video has been manipulated. Another issue is mismatched lighting or shadows, where the light on the face doesn’t align with the surroundings. Objects in the background might appear or disappear abruptly, which is often a result of the AI’s inability to render a seamless environment fully. These background inconsistencies can be a clear giveaway that the video has been altered.

Technical Clues

Deepfake videos often show technical clues that can help you spot them. For example, pixelation or artifacts around the face, especially near the edges, suggest the video has been manipulated. You may also notice visible seams or glitches where the face has been swapped or altered. Uneven resolution between different parts of the video is another indication that something isn’t right. These technical anomalies can be the result of the AI’s inability to create a perfect match between the manipulated and original footage.

Unnatural Behaviour

Deepfakes can sometimes be detected by unnatural behaviour. This includes image artifacts and blurriness that appear in parts of the video that should be crisp and clear. Audio deepfakes may also sound off, with unnatural intonations, robotic tones, or strange pauses. In video deepfakes, movements that don’t feel quite right or expressions that seem too exaggerated or stiff could also signal manipulation. Overall, if something feels “off” with the video’s behaviour, it’s worth scrutinising further for signs of a deepfake.

What Are The Ways to Prevent Deepfake Threats?

AI-based Detection Systems

Investing in AI-based detection systems that can automatically identify and flag deepfakes is crucial. These tools analyse video, audio, and image files for signs of manipulation.

Educating Employees and Stakeholders

Cybersecurity training programs should educate employees and stakeholders about the dangers of deepfakes. By teaching people to spot suspicious media and verify information, you can reduce the likelihood of falling victim to deepfake scams.

Implementing Strong Authentication Systems

Strengthening your authentication protocols—such as using multi-factor authentication (MFA)—can reduce the risk of social engineering attacks with the use of deepfakes. Biometric verification methods can further ensure the authenticity of identity.

Digital Watermarking and Metadata Tracking

Applying digital watermarks to images and videos can help trace the authenticity of media. Metadata tracking also plays a key role in verifying the source of content before it is shared. By using digital watermarks and metadata tracking, businesses can maintain the integrity of their media, making it easier to verify if the content has been tampered with. This also allows for faster identification of manipulated content and its original creator.

Regulation and Legislation

Governments need to pass legislation that penalises the malicious use of deepfakes. Strict laws can deter cybercriminals from exploiting deepfakes for fraudulent purposes, thus protecting both individuals and businesses. As regulations evolve, companies should stay informed about legal frameworks and take proactive measures to comply with laws designed to combat deepfakes. Regulatory actions help create a deterrent for malicious actors and reinforce the importance of responsible media use.

Use of Deepfake Detection Services

Several online services, like Deepware Scanner, Duckduckgoose, Google synthID, Intel Fakecatcher, Reality Defender, Sensity, Sentinel, etc., are designed to detect deepfakes by using various technologies, including temporal consistency checks, facial landmark analysis and flicker detection to gauge manipulated media. Employing this deepfake detection tool to verify fake content like videos, images, and audio content before it’s disseminated can reduce the risk of falling victim to fraud or misinformation.

Conclusion: Staying Vigilant Against Deepfake Threats

Deepfakes represent a growing cybersecurity challenge, with their potential to spread misinformation, damage reputations, and facilitate fraud. From manipulated videos and audio to real-time impersonations, the risks posed by deepfakes are both extensive and evolving. However, by understanding their workings, learning to detect anomalies, and implementing preventative measures like AI-based detection systems, strong authentication protocols, and digital watermarking, businesses and individuals can stay a step ahead of these threats.
