Mid-day 45th anniversary special: Beating AI-assisted cyber criminals at their o

The cyber police and experts are using artificial intelligence AI to counter cybercriminals who employ the technology to create deepfake movies clone voices and tailor phishing emails According to sources in the Cyber Cell of the Mumbai and the Maharashtra Police officials are employing AI algorithms to keep one step ahead of cybercriminals by examining big databases spotting trends in fraudulent activity and validating the authenticity of videos by correctly identifying matter generated by AICyber expert Yasir Shaikh at the Macksofy Technologies office in BKC PicAshish RajeRitesh Bhatia a leading cyber expert founder and director of V4WEB Cybersecurity said ldquoAI has now become a tool for cybercriminals in sophisticated cyber frauds especially those involving voice cloning phishing emails and deepfakes Cybercriminals are using AI to create realistic voice clones and videos of wellknown personalities which they then use to deceive peoplerdquo said He added ldquoFor example a deepfake video of a business tycoon was recently circulated falsely claiming that he had invested in a particular trading firm This led many people to trust the firm and subsequently fall victim to fraudrdquoTool for enforcing lawldquoAI systems help in analysing large datasets to detect patterns indicative of fraudulent activities aiding in the identification and prevention of cybercrimes in realtime We are using counter apps to determine if videos are AIgenerated particularly in cases related to deepfakes identity theft phishing emails and voice cloning where crooks use individualrsquos voices to extort large amounts from their parentsrdquo said a Cyber Cell officerldquoUsing these tools enables the identification and analysis of patterns detection of anomalies and prevention of cyberattacks before they inflict substantial harm By harnessing AI law enforcement agencies can bolster their capacity to trace and apprehend cybercriminals thereby improving digital safety for all It is crucial for law enforcement agencies to integrate AI into their investigative protocols particularly in combating cyber fraud Cybercriminals utilise AI extensively necessitating a proactive response from agencies to effectively combat these threatsrdquo Bhatia addedRitesh Bhatia founder and director V4WEB CybersecurityExplaining further about the use of AI in cyber frauds Bhatia stated ldquoAI algorithms can automate the creation of highly personalised phishing emails making them more convincing AI tools can also rapidly analyse vast amounts of data to identify vulnerabilities in security systems enabling cybercriminals to exploit these weaknesses before they are patchedrdquoAccording to Bhatia AIdriven bots can execute largescale fraud activities such as credential stuffing attacks where stolen usernames and passwords are used to gain unauthorised access to multiple accounts ldquoThe ability of AI to learn and adapt makes it a powerful tool in the hands of cybercriminals who can use it to continuously refine their tactics and evade detectionrdquo he saidForensic applicationsAccording to the experts AIpowered forensic tools help investigators reconstruct digital evidence and identify perpetrators Additionally natural language processing NLP can be used to monitor and analyse communications for suspicious activities ldquoBy automating routine tasks AI allows law enforcement agencies to allocate resources more efficiently focusing on complex cases that require human interventionrdquo said Yasir Shaikh founder of Macksofy TechnologiesShaikh said ldquoIn recent years image fraud has become common in social media applications and the online community In particular applying deep learning DL techniques to identify particular visual characteristics and overlay them on a different image or video has gained popularity on various platforms including Facebook Instagram Snapchat and Reddit This idea is often referred to as ldquodeepfakerdquo where ldquodeeprdquo denotes the use of deep learning neural networks DLNN and ldquofakerdquo denotes the definition of DLNN as being deceptive with respect to the original inputrdquoAccording to Shaikh deepfake detection solutions are ordinarily employed for recognising deepfake content and deep learning networks ldquoBut they can also be image and video analysis tools that can identify inconsistencies between facial expressions lighting and lip movement audio analysis tools that can identify speech patterns voice characteristics that have differences or audio track parts that do not make any sense and finally behavioural analysis tools that focus on the evaluation of aspects such as ductile and facial expressionsrdquo said addedAccording to Shaikh even deepfake generation models create identical replicas these fakes can still be identified using deep learning techniques or specialised forensic procedures The convolution procedures of nearly all deepfake generators are visible in the image Even while these traces can be found with meticulous forensic investigation the amount of data being shared on social media these days demands quick and automated solutionsldquoIf a system does not implement automatic triage it will be hard to do forensics analysis due to the sheer volume of data involved in assessing deepfakes Supervised deep learning techniques can readily identify convolutional traces remaining in deepfake images if the user supplies sufficient training data The investigating officer can determine whether using a deep learning technique based on MesoNet a tool used to identify whether the video is fakerdquoAdministrative tasksAccording to a Mumbai police official apart from its use in investigations AI tools are utilised in administrative tasks such as drafting content preparing letters to send notices to accused individuals and witnesses as well as generating letters seeking assistance from counterpart agencies ldquoIt makes work easier and less timeconsuming Sometimes we use apps like ChatGPT to generate questions to be asked to the accused in certain cases making the work more efficientrdquo said a Crime Branch officerAI and the legal professionAccording to advocate Aishwarya Kantawala the legal profession in India is evolving with the advent of new technologies including AIpowered tools like ChatGPT Reliance on such tools is increasing Among the advantages of using AI are prompt responses efficiency and accuracy in information accessibility and the fact that a lot of software is free ldquoThe disadvantages are that there is a risk of inaccuracyerror all data might not be reliable and can be unupdated There is a risk of job displacement and severe dependencyrdquo she saidldquoLimitations are language barriers nondigitisation of several documents and poor technological advancement among the majority of the populace Although the Indian legal system is grasping the idea of AI and software being used such as the Supreme Court Vidhik Anuvaad Software SUVAS an AIpowered translation tool no guidelines exist on the use of AI in legal practice Ultimately AI should be used mindfully and responsibly as one cannot thereafter shift the burden of responsibility for errorissuesinaccuracy upon a softwarerdquo she addedWhat is itIt is a novel deepfake detector used for zeroing in on
