iOS Lockdown Mode Feature: The Cyber Bouncer for Your iPhone!

Introduction

Apple launched Passkeys with iOS 16 as a more authentic and secure mechanism. It is safer than passwords, and it is more efficient in comparison to passwords. Apple users using iOS 16 passkeys features should enable two-factor authentication.  The passkeys are an unchallenging mechanism than the passwords for the passkeys. The user just has to open the apps and websites, and then the biometric sensor automatically recognises the face and fingerprints. There can be a PIN and pattern used to log instead of passwords. The passkeys add an extra coating of protection to the user’s systems against cyber threats like phishing attacks by SMS and one-time password-based. In a report 9 to 5mac, there is confirmation that 95% of users are using passkeys. Also, with the passkeys, users’ experience will be better, and it is a more security-proof mechanism. The passwords were weak, reused credentials and credentials leaked, and the chances of phishing attacks were real.

What are passkeys?

Passkey is a digital key linked to users’ accounts and websites or applications. Passkeys allow the user to log into any application and website without entering passwords, usernames, or other details. The aim of this new feature is to replace the old long pattern of entering passwords for going through any websites and applications.

The passkeys are developed by Microsoft, Apple, and Google together, and it is also called FIDO Authentication (Fast identity online). It eliminates the need to remember passwords and the need for typing. So, the passkeys work as they replace the password with a unique digital key, which is tied to the account then, the key is stored in the device itself, and it is end-to-end encrypted. The passkeys will always be on the sites on which users specifically created them. the passkeys use the technology of cryptography for more security purposes.  And the passkeys guarantee against the phish.

And since the passkeys follow FIDO standards so, this also can be used for third-party nonapple devices as the third-party device generate a QR code that enables the iOS user to scan that to log in. It will recognise the face of the person for authentication and then asks for permission on another device to deny or allow.

How are passkeys more secure than passwords?

The passkeys follow the public key cryptographic protocols that support the security keys, and they work against phishing and other cyber threats. It is more secure than SMS and apps based on one-time passwords. And another type of multi-factor authentication.

Why are passwords insecure?

The users create passwords easily, and it is wondering if they are secure. The very important passwords are short and easy to crack as they generally relate to the user’s personal information or popular words. One password is reused by the user to the different accounts, and then, in this case, hacking one account gives access to all accounts to the hackers. The problem is that passwords have inherent flaws, like they could be easily stolen.

Are passkeys about to become obligatory?

Many websites restrict the type of passwords, as some websites ask for mixtures of numbers and symbols, and many websites ask for two-factor authentication. There is no surety about the obligation of passkeys widespread as it is still a new concept and it will take time, so it is going to be optional for a while.

• There was a case of a Heartland payment system data breach, and Heartland was handling over 100 million monthly credit card transactions for 175,000 retailers at the time of the incident. Visa and MasterCard detected the hack in January 2009 when they notified Heartland of suspicious transactions. And this happened due to a password breach. The corporation paid an estimated $145 million in settlement for illegal payments. Today, data-driven breaches affect millions of people’s personal information.
• GoDaddy reported a security attack in November that affected the accounts of over a million of its WordPress customers. The attacker acquired unauthorised access to GoDaddy’s Managed WordPress hosting environment by hacking into the provisioning system in the company’s legacy Managed WordPress code.

Conclusion

The use of strong and unique passwords is an essential requirement to safeguard information and data from cyberattacks, but still, passwords have its own disadvantages. And by the replacement of passwords, a passkey, a digital key that ensures proper safety and there is security against cyberattacks and cybercrimes through passkey. There are cases above-mentioned that happened due to the password’s weaker security. And in this technology world, there is a need for something for protection and prevention from cybercrimes, and the world dumps passwords and adopts passkeys.

Introduction

Sexual Offences against children have recently come under scrutiny after the decision of the Madras High Court which has ruled that watching and downloading child sexual porn is an inchoate crime. In response, the Supreme Court, on 23 September 2024, ruled that Section 15 of the POCSO and Section 67B of the IT Act penalise any form of use of child pornography, including storing and watching such pornographic content. Along with this, the Supreme Court has further recommended replacing the term “Child Pornography” which it said acts as a misnomer and does not capture the full extent of the crime, with a more inclusive term “Child Sexual Exploitative and Abuse Material” (CESAM). This term would more accurately reflect the reality that these images and videos are not merely pornographic but are records of incidents, where a child has either been sexually exploited and abused or where any abuse of children has been portrayed through any self-generated visual depiction.

Intermediaries cannot claim exemption from Liability U/S 79 

Previously, intermediaries claimed safe harbour by only complying with the requirements stipulated under the  MOU. As per the decision of the SC, now, an intermediary cannot claim exemption from the liability under Section 79 of the IT Act for any third-party information, data, or communication link made available or hosted by it unless due diligence is conducted by it and compliance is made of these provisions of the POCSO Act. This is as per the provisions of Sections 19 and 20 of the POCSO read with Rule 11 of the POCSO Rules which have a mandatory nature.

The due diligence under section 79 of the IT Act includes the removal of child pornographic content and immediate reporting of such content to the concerned police units in the manner specified under the POCSO Act and the Rules. In this way, the Supreme Court has broadened the Interpretation and scope of the ‘Due Diligence’ obligation under section 79 of the IT Act. It was also stated that is to be duly noted that merely because an intermediary complies with the IT Act, will not absolve it of any liability under the POCSO. This is unless it duly complies with the requirements and procedure set out under it, particularly Section 20 of the POCSO Act and Rule 11 of the POCSO Rules.

Bar on Judicial Use of the term ‘Child Porn’

Supreme Court found that the term child pornography can be trivialised as pornography is often seen as a consensual act between adults. Supreme Court emphasised using the term Child Sexual Exploitative and Abuse Material  (CESAM) as it would emphasise the exploitation of children highlight the criminality of the act and shift the focus to a more robust framework to counter these crimes. The Supreme Court also stated that the Union of India should consider amending the POCSO Act to replace the "child pornography" term with "child sexual exploitative and abuse material" (CSEAM). This would reflect more accurately on the reality of such offences. Supreme Court also directed that the term "child pornography" shall not be used in any judicial order or judgment, and instead, the term "CSEAM" should be endorsed.

Curbing CSEAM Content on Social Media Platforms

Social Media Intermediaries and Expert Organisations play an important role in curbing CESAM content. Per the directions of the Apex Court, a need to impart positive age-appropriate sex education to prevent youth from engaging in harmful sexual behaviours, including the distribution, and viewing of CSEAM is important and all stakeholders must engage in proactive measures to counter these offences which are under the umbrella of CSEAM. This should entail promoting age-appropriated and lawful content on social media platforms and social media platforms to ensure compliance with applicable provisions.  

Conclusion 

In light of the Supreme Court’s landmark ruling, it is imperative to acknowledge the pressing necessity of establishing a safer online environment that shields children from exploitation. The shift towards using "Child Sexual Exploitative and Abuse Material" (CSEAM) emphasizes the severity of the crime and the need for a vigilant response. The social media intermediaries must respect their commitment to report and remove exploitive content and must ensure compliance with POCSO and IT regulations. Furthermore, comprehensive, age-appropriate sex education can also be used as a preventive measure, educating young people about the moral and legal ramifications of sexual offences, encouraging respect and awareness and ensuring safer cyberspace.

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.

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.
