Introduction:

With improved capabilities and evasion strategies, the Vultur banking Trojan has reappeared and is a serious danger to Android users. The virus now employs numerous encrypted payloads, encrypted communication, and poses as legitimate apps. It is transmitted by trojanized dropper programs on the Google Play Store. Vultur targets victims via phone calls and SMS messages. With the help of this updated version of Vultur, attackers may take total control of compromised devices. They can perform a variety of remote control operations like install, remove, upload, and download files, halt the execution of programs, and circumvent the lock screen. The virus is now far more hazardous than it was previously because of its improved capacity to remotely access and manipulate machines.

Overview: 

The Android banking malware Vultur is well-known for its ability to record screens. It was first identified by ThreatFabric in March 2021 and targets banking apps for remote control and keylogging.

The malicious apps were hosted on the Google Play Store by the Brunhilda dropper-framework, which was used for its distribution. Initial versions of the program used reputable remote access tools such as ngrok and AlphaVNC.

Hybrid attacks have been used in recent operations to disseminate the Brunhilda dropper via phone calls and SMS. The dropper uses a number of payloads to distribute an upgraded version of Vultur.

41 new Firebase Cloud Messaging (FCM) commands and seven new Command-and-Control (C2) methods are included in the most recent version of Vultur. 

With the help of Android's Accessibility Services, these enhancements concentrate on remote access functionality that improves the malware's capacity to communicate with the victim's screen.

Modus operandi of Attack:

Hybrid Attack Method:

• Utilizes a phone call, two SMS messages, and trick users into installing malware.

• First SMS tricks victims into calling a certain number by claiming to have made significant, unlawful transactions, which gives the impression of urgency.

• Although there was no transaction in reality, the urgency motivates victims to act quickly.

Trozonized MacAfee App:

• The victims are told to install a trojanized version of the McAfee Security program from a given link during the phone call.

• This app looks harmless and has features similar to the original McAfee Security app, but it's actually the Brunhilda dropper.

• The victims are misled into assuming that the security software they are installing is authentic.

Execution of Vultur Payloads:

• Three payloads connected to Vultur are decrypted and executed via the Brunhilda dropper.

• Threat actors can carry out a variety of malicious operations, including keylogging and screen recording, on the victim's mobile device thanks to these payloads, which grant them total access over it.

• The infected device of the victim allows the threat actors to launch additional assaults or obtain private data.

Indication of the attack:

The symptoms of a Vultur banking Trojan infection include:

• Remote Access: This malware gives the hacker the ability to remotely use the infected device via clicking, scrolling, and swiping through Android's accessibility services.

• File Management: Through this, the malware is able to copy, share, remove, create, and locate files from devices it has infected.

• App Blocking: For instance; the malicious software can be programmed to stop the victims from opening a certain bunch of apps.

• Custom Notifications: Attackers can embed the malware with the functionality of displaying the customized notifications in the taskbar.

• Keyguard Disabling: The malware may be designed to turn off Screen Lock Guard feature so the lock screen security measure can be easily bypassed.

• Encrypted C2 Communication: The malware chooses AES data encryption, with Base64 text encoding to provide hidden traces for C2 communication.

• Payload Decryption: The malware uses native code, mostly written in C as well as C++, to decode the goods, thus, making a process of reversing more complicated.

• Spying on Financial Apps: The malware uses screen-streaming and keylogging as ways of acquiring facts about the victim’s mobile banking applications.

Indicator of Compromise:

Steps to be taken when your device is compromised?.

• Change the password: Vultur revealed multiple cases where threat actors can gain access to your financial and private information. To safeguard your account, reset passwords on other devices and create secure, unique passwords during the time. Instead of simply storing your password, a reputed password manager is the most secure way of storing information.

• Keep an eye on your transactions and accounts: It is advised that you regularly monitor your online accounts for any unusual or illegal activity. Keep a watch out for any irregularities, and report anything suspicious to the provider or authorities straight immediately.. Also check your credit reports and scores attentively to make sure that your identity or cards are not compromised.

• Make sure you are using identity theft protection: Many pieces of information about your identity are stored in an Android device. Cyber criminals can easily get hold of this data and make major damage to you, including stealing your money and identity. For your own protection, some of the identity theft protection services that monitor all your personal information and notify you on any unusual activity and, as well, helps you to freeze your accounts would be beneficial.

• Immediately get in touch with your banks and credit card companies: Your personal information such as credit card or bank details is of high risk to be exposed to hackers who could use them to make transactions without you knowing. You should inform your credit card and the lending bank about the situation as soon as possible. They would help you if your cards were used for fraudulent charges and your card be either frozen or canceled. Besides, they can get new cards issued.

• Make your contacts alert regarding the fraud you faced: Threat actors may access your social media or email accounts to send phishing messages or spam to people in your contact list, if they gain access to them. Moreover, they may masquerade as you and try to extort cash from you or disclose your personal information. Distributing a message to your contacts stating that they shouldn’t open or reply to any messages that look like they are not from you and look very strange or suspicious, will be a great idea.

• Make a backup and wipe all your device content in factory settings: You can always factory reset your device to ensure it is free of viruses and spyware. In other words, it will refresh Android and leave behind all your data and settings. Back up all the critical data prior to processing it and assure that everything is restored from a trustworthy source only.

Preventive measures to be taken:

• Avoid calling back to the hacker: If a hacker texts you claiming to have approved a sizable bank transaction, refrain from picking up the phone. You can always check by making a call to your own financial intuition. However, never pick up on an unknown number that someone else sends you.

• Avoid sideloading apps and shortened URLs: Try to avoid sideloading apps. That's the moment when you install apps from unofficial sources. Users may be tricked into downloading malware using short URLs.

• Be careful granting permissions: Be cautious when allowing permissions for apps. Think about whether an app really needs access to specific data or device functions.

• Limit the apps you have on your phone: On your phone, having plenty of apps might sometimes make it easier to become infected with malware. Over time, these apps may allow harmful code to enter your system, and the more programs you have to update and monitor, the greater the risk to your Android device. This is how to remove pointless apps from your Android device.

• Download apps from reputable sources: Additionally, make sure the programs you download are from reputable and authorized developers. Do your homework and read reviews before you install.

• Keep your Android device updated: With the help of software and security upgrades, your phone can automatically maintain security. Remember to install them.

• Have good antivirus software on all your devices: The best defense against malware on all of your devices is to install antivirus software. By blocking you from clicking on potentially dangerous links, antivirus software can keep malware off your devices and keep hackers from accessing your personal data.

Conclusion:

Vultur is a terrifying banking Trojan with a great deal of sophistication. It's unsettling that hackers can take complete control of your Android device, which emphasizes how crucial it is that you take precautions. It all starts with a text message in these attacks. You must take the time to independently contact your banking institution to check whether there are any issues. You may prevent having your entire device compromised and your personal information exposed by simply investing an additional few minutes.

Introduction

According to a draft of the Digital Personal Data Protection Bill, 2023, the Indian government may have the authority to reduce the age at which users can agree to data processing to 14 years. Companies requesting consent to process children’s data, on the other hand, must demonstrate that the information is handled in a “verifiably safe” manner.

The Central Government might change the age limit for consent

The proposed Digital Personal Data Protection Bill 2022 in India attempts to protect child’s personal data under the age of 14 through several provisions. The proposed lower age of consent in India under the Digital Personal Data Protection Bill 2022 is to loosen relevant norms and fulfil the demands of Internet corporations. After a year, the government may reconsider the definition of a child with the goal of expanding coverage to children under the age of 14. The proposed shift in the age of consent has elicited varied views, with some experts suggesting that it might potentially expose children to data processing concerns.

The definition of a child is understood to have been amended in the data protection Bill, which is anticipated to be submitted in Parliament’s Monsoon session, to an “individual who has not completed the age of eighteen years or such lower age as the central government may notify.” A child was defined as an “individual who has not completed eighteen years of age” in the 2022 draft.

Under deemed consent, the government has also added the 'legitimate business interest' clause

This clause allows businesses to process personal data without obtaining explicit consent if it is required for their legitimate business interests. The measure recognises that corporations have legitimate objectives, such as innovation, that can be pursued without jeopardising privacy.‍

Change in Data Protection Boards

The Digital Personal Data Protection Bill 2022, India’s new plan to secure personal data, represents a significant shift in strategy by emphasising outcomes rather than legislative compliance. This amendment will strengthen the Data Protection Board’s position, as its judgments on noncompliance complaints will establish India’s first systematic jurisprudence on data protection. The Cabinet has approved the bill and may be introduced in Parliament in the Monsoon session starting on July 20.

The draft law leaves the selection of the Data Protection Board’s chairperson and members solely to the discretion of the central government, making it a central government set-up board. The government retains control over the board’s composition, terms of service, and so on. The bill does specify, however, that the Data Protection Board would be completely independent and will have a strictly adjudicatory procedure to adjudicate data breaches. It has the same status as a civil court, and its rulings can be appealed.

India's first regulatory body in Charge of preserving privacy

Some expected amendments to the law include a blacklist of countries to which Indian data cannot be transferred and fewer penalties for data breaches. The bill’s scope is limited to processing digital personal data within Indian territory, which means that any offline personal data and anything not digitised will be exempt from the legislation’s jurisdiction. Furthermore, the measure is silent on the governance of digital paper records.

Conclusion

The Digital Personal Data Protection Bill 2022 is a much-needed piece of legislation that will replace India’s current data protection regime and assist in preserving individuals’ rights. Central Government is looking for a change in the age for consent from 18 to 14 years. The bill underlines the need for verifiable parental consent before processing a child’s personal data, including those under 18. This section seeks to ensure that parents or legal guardians have a say in the processing of their child’s personal data.

Introduction

Deepfake technology, which combines the words "deep learning" and "fake," uses highly developed artificial intelligence—specifically, generative adversarial networks (GANs)—to produce computer-generated content that is remarkably lifelike, including audio and video recordings. Because it can provide credible false information, there are concerns about its misuse, including identity theft and the transmission of fake information. Cybercriminals leverage AI tools and technologies for malicious activities or for committing various cyber frauds. By such misuse of advanced technologies such as AI, deepfake, and voice clones. Such new cyber threats have emerged. 

India Topmost destination for deepfake attacks

According to Sumsub’s identity fraud report 2023, a well-known digital identity verification company with headquarters in the UK. India, Bangladesh, and Pakistan have become an important participants in the Asia-Pacific identity fraud scene with India’s fraud rate growing exponentially by 2.99% from 2022 to 2023. They are among the top ten nations most impacted by the use of deepfake technology. Deepfake technology is being used in a significant number of cybercrimes, according to the newly released Sumsub Identity Fraud Report for 2023, and this trend is expected to continue in the upcoming year. This highlights the need for increased cybersecurity awareness and safeguards as identity fraud poses an increasing concern in the area. 

How Deeepfake Works 

Deepfakes are a fascinating and worrisome phenomenon that have emerged in the modern digital landscape. These realistic-looking but wholly artificial videos have become quite popular in the last few months. Such realistic-looking, but wholly artificial, movies have been ingrained in the very fabric of our digital civilisation as we navigate its vast landscape. The consequences are enormous and the attraction is irresistible.  

Deep Learning Algorithms

Deepfakes examine large datasets, frequently pictures or videos of a target person, using deep learning techniques, especially Generative Adversarial Networks. By mimicking and learning from gestures, speech patterns, and facial expressions, these algorithms can extract valuable information from the data. By using sophisticated approaches, generative models create material that mixes seamlessly with the target context. Misuse of this technology, including the dissemination of false information, is a worry. Sophisticated detection techniques are becoming more and more necessary to separate real content from modified content as deepfake capabilities improve.

Generative Adversarial Networks

Deepfake technology is based on GANs, which use a dual-network design. Made up of a discriminator and a generator, they participate in an ongoing cycle of competition. The discriminator assesses how authentic the generated information is, whereas the generator aims to create fake material, such as realistic voice patterns or facial expressions. The process of creating and evaluating continuously leads to a persistent improvement in Deepfake's effectiveness over time. The whole deepfake production process gets better over time as the discriminator adjusts to become more perceptive and the generator adapts to produce more and more convincing content. 

 Effect on Community

The extensive use of Deepfake technology has serious ramifications for several industries. As technology develops, immediate action is required to appropriately manage its effects. And promoting ethical use of technologies. This includes strict laws and technological safeguards. Deepfakes are computer trickery that mimics prominent politicians' statements or videos. Thus, it's a serious issue since it has the potential to spread instability and make it difficult for the public to understand the true nature of politics. Deepfake technology has the potential to generate totally new characters or bring stars back to life for posthumous roles in the entertainment industry. It gets harder and harder to tell fake content from authentic content, which makes it simpler for hackers to trick people and businesses.

Ongoing Deepfake Assaults In India

Deepfake videos continue to target popular celebrities, Priyanka Chopra is the most recent victim of this unsettling trend. Priyanka's deepfake adopts a different strategy than other examples including actresses like Rashmika Mandanna, Katrina Kaif, Kajol, and Alia Bhatt. Rather than editing her face in contentious situations, the misleading film keeps her look the same but modifies her voice and replaces real interview quotes with made-up commercial phrases. The deceptive video shows Priyanka promoting a product and talking about her yearly salary, highlighting the worrying development of deepfake technology and its possible effects on prominent personalities.

Actions Considered by Authorities

A PIL was filed requesting the Delhi High Court that access to websites that produce deepfakes be blocked. The petitioner's attorney argued in court that the government should at the very least establish some guidelines to hold individuals accountable for their misuse of deepfake and AI technology. He also proposed that websites should be asked to identify information produced through AI as such and that they should be prevented from producing illegally. A division bench highlighted how complicated the problem is and suggested the government (Centre) to arrive at a balanced solution without infringing the right to freedom of speech and expression (internet).  

Information Technology Minister Ashwini Vaishnaw stated that new laws and guidelines would be implemented by the government to curb the dissemination of deepfake content. He presided over a meeting involving social media companies to talk about the problem of deepfakes. "We will begin drafting regulation immediately, and soon, we are going to have a fresh set of regulations for deepfakes. this might come in the way of amending the current framework or ushering in new rules, or a new law," he stated.

Prevention and Detection Techniques

To effectively combat the growing threat posed by the misuse of deepfake technology, people and institutions should place a high priority on developing critical thinking abilities, carefully examining visual and auditory cues for discrepancies, making use of tools like reverse image searches, keeping up with the latest developments in deepfake trends, and rigorously fact-check reputable media sources. Important actions to improve resistance against deepfake threats include putting in place strong security policies, integrating cutting-edge deepfake detection technologies, supporting the development of ethical AI, and encouraging candid communication and cooperation. We can all work together to effectively and mindfully manage the problems presented by deepfake technology by combining these tactics and adjusting the constantly changing terrain.

Conclusion

Advanced artificial intelligence-powered deepfake technology produces extraordinarily lifelike computer-generated information, raising both creative and moral questions. Misuse of tech or deepfake presents major difficulties such as identity theft and the propagation of misleading information, as demonstrated by examples in India, such as the latest deepfake video involving Priyanka Chopra. It is important to develop critical thinking abilities, use detection strategies including analyzing audio quality and facial expressions, and keep up with current trends in order to counter this danger. A thorough strategy that incorporates fact-checking, preventative tactics, and awareness-raising is necessary to protect against the negative effects of deepfake technology. Important actions to improve resistance against deepfake threats include putting in place strong security policies, integrating cutting-edge deepfake detection technologies, supporting the development of ethical AI, and encouraging candid communication and cooperation. We can all work together to effectively and mindfully manage the problems presented by deepfake technology by combining these tactics and making adjustments to the constantly changing terrain. Creating a true cyber-safe environment for netizens.
