Demystifying Digital Forensics: Understanding the Differences Between Copying, Cloning, and Imaging
Introduction:
Welcome to the second edition of our blog on Digital forensics series. In our previous blog we discussed what digital forensics is, the process followed by the tools, and the subsequent challenges faced in the field. Further, we looked at how the future of Digital Forensics will hold in the current scenario. Today, we will explore differences between 3 particular similar sounding terms that vary significantly in functionality when implemented: Copying, Cloning and Imaging.
In Digital Forensics, the preservation and analysis of electronic evidence are important for investigations and legal proceedings. Replication of the data and devices is one of the fundamental tasks in this domain, without compromising the integrity of the original evidence.
Three primary techniques -- copying, cloning, and imaging -- are used for this purpose. Each technique has its own strengths and is applied according to the needs of the investigation.
In this blog, we will examine the differences between copying, cloning and imaging. We will talk about the importance of each technique, their applications and why imaging is considered the best for forensic investigations.
Copying
Copying means duplicating data or files from one location to another. When one does copying, it implies that one is using standard copy commands. However, when dealing with evidence, it might be hard to use copy only. It is because the standard copy can alter the metadata and change the hidden or deleted data .
The characteristics of copying include:
- Speed: copying is simpler and faster,compared to cloning or imaging.
- Risk: The risk involved in copying is that the metadata might be altered and all the data might be captured.
Cloning
It is the process where the transfer of the entire contents of a hard drive or a storage device is done on another storage device. This process is known as cloning . This way, the cloning process captures both the active data and the unallocated space and hidden partitions, thus containing the whole structure of the original device. Cloning is generally used at the sector level of the device. Clones can be used as the working copy of a device .
Characteristics of cloning:
- bit-for-bit replication: cloning keeps the exact content and the whole structure of the original device.
- Use cases: cloning is used when it is needed to keep the original device intact for further examination or a legal affair.
- Time consuming: Cloning is usually longer in comparison to simple copying since it involves the whole detailed replication. Though it depends on various factors like the size of the storage device, the speed of the devices involved, and the method of cloning.
Imaging:
It is the process of creating a forensic image of a storage device. A forensic image is a replica copy of every bit of data that was on the source device, this including the allocated, unallocated, and the available slack space .
The image is then used for analysis and investigation, and the original evidence is left untouched. Images can’t be used as the working copies of a device. Unlike cloning, which produces working copies, forensic images are typically used for analysis and investigation purposes and are not intended for regular use as working copies.
Characteristics of Imaging:
- Integrity: Imaging ensures the integrity and authenticity of the evidence produced
- Flexibility: Forensic image replicas can be mounted as a virtual drive to create image-specific mode for analysis of data without affecting the original evidence .
- Metadata: Imaging captures metadata associated with the data, thus promoting forensic analysis.
Key Differences
- Purpose: Copying is for everyday use but not good for forensic investigations requiring data integrity. Cloning and imaging are made for forensic preservation.
- Depth of Replication: Cloning and imaging captures the entire storage device including hidden, unallocated, and deleted data whereas copying may miss crucial forensic data.
- Data Integrity: Imaging and cloning keep the integrity of the original evidence thus making them suitable for legal and forensic use. Which is a critical aspect of forensic investigations.
- Forensic Soundness: Imaging is considered the best in digital forensics due to its comprehensive and non-invasive nature.
- Cloning is generally from one hard disk to another, where as imaging creates a compressed file that contains a snapshot of the entire hard drive or a specific partitions
Conclusion
Therefore, copying, cloning, and imaging all deal with duplication of data or storage devices with significant variations, especially in digital forensic. However, for forensic investigations, imaging is the most selected approach due to the correct preservation of the evidence state for any analysis or legal use . Therefore, it is essential for forensic investigators to understand these rigorous differences to avail of real and uncontaminated digital evidence for their investigation and legal argument.

Executive Summary:
A morphed video of the actor Anup Soni popular on social media promoting IPL betting Telegram channel is found to be fake. The audio in the morphed video is produced through AI voice cloning. AI manipulation was identified by AI detection tools and deepfake analysis tools. In the original footage Mr Soni explains a case of crime, a part of the popular show Crime Patrol which is unrelated to betting. Therefore, it is important to draw the conclusion that Anup Soni is in no way associated with the betting channel.
Claims:
The facebook post claims the IPL betting Telegram channel which belongs to Rohit Khattar is promoted by Actor Anup Soni.
Fact Check:
Upon receiving the post, the CyberPeace Research Team closely analyzed the video and found major discrepancies which are mostly seen in AI-manipulated videos. The lip sync of the video does not match the audio. Taking a cue from this we analyzed using a Deepfake detection tool by True Media. It is found that the voice of the video is 100% AI-generated.
We then extracted the audio and checked in an audio Deepfake detection tool named Hive Moderation. Hive moderation found the audio to be 99.9% AI-Generated.
We then divided the video into keyframes and reverse searched one of the keyframes and found the original video uploaded by the YouTube channel named LIV Crime.
Upon analyzing we found that in the 3:18 time frame the video was edited, and altered with an AI voice.
Hence, the viral video is an AI manipulated video and it’s not real. We have previously debunked such AI voice manipulation with different celebrities and politicians to misrepresent the actual context. Netizens must be careful while believing in such AI manipulation videos.
Conclusion:
In conclusion, the viral video claiming that IPL betting Telegram channel promotion by actor Anup Soni is false. The video has been manipulated using AI voice cloning technology, as confirmed by both the Hive Moderation AI detector and the True Media AI detection tool. Therefore, the claim is baseless and misleading.
- Claim: An IPL betting Telegram channel belonging to Rohit Khattar promoted by Actor Anup Soni.
- Claimed on: Facebook
- Fact Check: Fake & Misleading

Social media platforms serve as an ideal breeding ground for cybercrime. A new fraud called ‘WhatsApp Pink’ has emerged, promising new features and an improved UI. Several law enforcement and government agencies have already issued severe caution against the program, which is used to hack mobile phones and steal personal information.
What is a pink WhatsApp Scam?
WhatsApp is on a roll with new features, but the messaging app is also experiencing an increase in a new type of scam. The WhatsApp Pink scam, as it is known, is gaining steam. Police and government organisations in several states, including Mumbai, Kerala, and Karnataka, have warned about the scam. A North Region cybercrime wing tweet warned, “WHATSAPP PINK – A Red Alert for Android Users.” The government’s cybersecurity organisations have warned about the rise in pink WhatsApp scams.
Scammers and hackers target WhatsApp users with fake messages via the network in this scam. According to reports, the message contains a link directing users to download WhatsApp Pink, a bogus messaging program. According to sources, scammers are targeting many people with the promise that the next version will have a better interface and additional features.
The application also steals critical financial information such as OTP, bank account information, and contact information. When people open the link, harmful software is installed on their mobile phones, and scammers get access to the phones. The user may even lose access to their phone by downloading the app.
According to the advisory
The news about ‘New Pink Look WhatsApp with extra features’ recently circulating among WhatsApp users is a hoax that can lead to hacking of your mobile through malicious software.” It is uncommon for fraudsters to devise new tricks and methods to entice naive consumers into falling into their trap and committing cyber fraud. It is the users’ responsibility to be Aware, Alert, and Attentive to these types of frauds in order to be safe and secure in the digital world.”
The link that is present in the message, according to a notice from the police, is a phishing effort. By clicking the link, the user runs the risk of having their device compromised, which might allow scammers to steal their device information or use it without their permission.
Users run the possibility of suffering negative outcomes if they click the Pink WhatsApp link, as the Mumbai Police have warned. These dangers include financial loss, identity theft, spam attacks, unauthorised access to contact information and saved images, and even total loss of control over mobile devices.
Guidelines against the Scam
- If a user has installed the fake WhatsApp, the authorities have instructed that they uninstall it immediately by going into the mobile settings, selecting WhatsApp with the pink logo in Apps, and then uninstalling it.
- Users have been advised to exercise caution when clicking links from untrustworthy websites unless they have previously verified their legitimacy. Users are advised to only download and update software from reliable sites such as the official Google Play Store, the iOS App Store, and so on.
- individuals using the site have been told not to send any links or communications to other persons until they have received proper authentication or verification.
- To avoid misuse, users are advised not to disclose any personal or financial information, including passwords, login information, and credit or debit card information, to anybody online. Furthermore, in order to defend themselves against fraud attempts, users are encouraged to stay up to date on the most recent news and changes in order to be informed and careful about cybercriminal activities.
Why do Scammer target WhatsApp
WhatsApp is the world’s most popular messaging service; it can reach out to considerably more prospective victims than it could with another tool. A scammer’s victims are almost certainly using WhatsApp. If all their victims are in one app, the criminal can easily handle their activities.
Conclusion
WhatsApp users may reduce their chances of being victims of the pink WhatsApp scam significantly by following the guidelines issued by the advisory. WhatsApp has become the primary target for scams, as there is a large number of the population using WhatsApp so it will be easy for the Scammer to steal critical personal information and target another victim through WhatsApp. The pink WhatsApp Scam is exactly like it.

Introduction
The rise of unreliable social media newsgroups on online platforms has significantly altered the way people consume and interact with news, contributing to the spread of misinformation and leading to sources of unverified and misleading content. Unlike traditional news outlets that adhere to journalistic standards, these newsgroups often lack proper fact-checking and editorial oversight, leading to the rapid dissemination of false or distorted information. Social media transformed individuals into active content creators. Social media newsgroups (SMNs) are social media platforms used as sources of news and information. According to a survey by the Pew Research Center (July-August 2024), 54% of U.S. adults now rely on social media for news. This rise in SMNs has raised concerns over the integrity of online news and undermines trust in legitimate news sources. Social media users are advised to consume information and news from authentic sources or channels available on social media platforms.
The Growing Issue of Misinformation in Social Media Newsgroups
Social media newsgroups have become both a source of vital information and a conduit for misinformation. While these platforms allow rapid news sharing and facilitate political and social campaigns, they also pose significant risks of unverified information. Misleading information, often driven by algorithms designed to maximise user engagement, proliferates in these spaces. This has led to increasing challenges, as SMNs cater to diverse communities with varying political affiliations, gender demographics, and interests. This sometimes results in the creation of echo chambers where information is not critically assessed, amplifying the confirmation bias and enabling the unchecked spread of misinformation. A prominent example is the false narratives surrounding COVID-19 vaccines that spread across SMNs, contributing to widespread vaccine hesitancy and public health risks.
Understanding the Susceptibility of Online Newsgroups to Misinformation
Several factors make social media newsgroups particularly susceptible to misinformation. Some of the factors are listed below:
- The lack of robust fact-checking mechanisms in social media news groups can lead to false narratives which can spread easily.
- The lack of expertise from admins of online newsgroups, who are often regular users without journalism knowledge, can result in the spreading of inaccurate information. Their primary goal of increasing engagement may overshadow concerns about accuracy and credibility.
- The anonymity of users exacerbates the problem of misinformation. It allows users to share unverified or misleading content without accountability.
- The viral nature of social media also leads to the vast spread of misinformation to audiences instantly, often outpacing efforts to correct it.
- Unlike traditional media outlets, online newsgroups often lack formal fact-checking processes. This absence allows misinformation to circulate without verification, making it easier for inaccuracies to go unchallenged.
- The sheer volume of user engagement in the form of posts has created the struggle to moderate content effectively imposing significant challenges.
- Social Media Platforms have algorithms designed to enhance user engagement and inadvertently amplify sensational or emotionally charged content, which is more likely to be false.
Consequences of Misinformation in Newsgroups
The societal impacts of misinformation in SMNs are profound. Political polarisation can fuel one-sided views and create deep divides in democratic societies. Health risks emerge when false information spreads about critical issues, such as the anti-vaccine movements or misinformation related to public health crises. Misinformation has dire long-term implications and has the potential to destabilise governments and erode trust in media, in both traditional and social media leading to undermining democracy. If unaddressed, the consequences could continue to ripple through society, perpetuating false narratives that shape public opinion.
Steps to Mitigate Misinformation in Social Media Newsgroups
- Educating users in social media literacy education can empower critical assessment of the information encountered, reducing the spread of false narratives.
- Introducing stricter platform policies, including penalties for deliberately sharing misinformation, may act as a deterrent against sharing unverified information.
- Collaborative fact-checking initiatives with involvement from social media platforms, independent journalists, and expert organisations can provide a unified front against the spread of false information.
- From a policy perspective, a holistic approach that combines platform responsibility with user education and governmental and industry oversight is essential to curbing the spread of misinformation in social media newsgroups.
Conclusion
The emergence of Social media newsgroups has revolutionised the dissemination of information. This rapid spread of misinformation poses a significant challenge to the integrity of news in the digital age. It gets further amplified by algorithmic echo chambers unchecked user engagement and profound societal implications. A multi-faceted approach is required to tackle these issues, combining stringent platform policies, AI-driven moderation, and collaborative fact-checking initiatives. User empowerment concerning media literacy is an important factor in promoting critical thinking and building cognitive defences. By adopting these measures, we can better navigate the complexities of consuming news from social media newsgroups and preserve the reliability of online information. Furthermore, users need to consume news from authoritative sources available on social media platforms.
