#FactCheck - "Deep fake Falsely Claimed as a photo of Arvind Kejriwal welcoming Elon Musk when he visited India to discuss Delhi’s administrative policies.”

Executive Summary:

CVE 2024-3094 is a backdoor vulnerability recently found in Kali Linux installations that happened between March 26th to 29th. This vulnerability was found in XZ package version 5.6.0 to 5.6.1. It could allow the malicious actor to compromise SSHD authentication, and grant unauthorized access to the entire system remotely. The users who have installed or updated Kali Linux during the said time are advised to update their system to safeguard against this vulnerability. 

The Dangerous Backdoor

The use of the malicious implant found in XZ Utils as a remote code execution tool makes it more dangerous, because of its ability to compromise the affected systems. Initially, researchers believed the vulnerability enabled an authentication bypass for the OpenSSH server (SSHD) process. However, further analysis revealed it is better characterized as a remote code execution (RCE) vulnerability.

The backdoor intercepts the RSA_public_decrypt function, verifies the host's signature using a fixed Ed448 key, and if successful, executes malicious code passed by the attacker via the system() function. This leaves no trace in SSHD logs and makes it difficult to detect the vulnerability. 

Impacted Linux Distributions

The compromised versions of XZ Utils have been found in the following Linux distributions released in March 2024:

• Kali Linux (between March 26 and March 29)
• openSUSE Tumbleweed and openSUSE MicroOS (March 7 to March 28)
• Fedora 41, Fedora Rawhide, and Fedora Linux 40 beta
• Debian (testing, unstable, and experimental distributions only)
• Arch Linux container images (February 29 to March 29)
• Meanwhile, distributions such as Red Hat Enterprise Linux (RHEL), SUSE Linux Enterprise, openSUSE Leap, and Debian Stable are not believed to be affected.

How Did This Happen?

The malicious code appears to have been inserted by taking advantage of a typical control transfer vulnerability. The original maintainer of the XZ Libs project on GitHub handed over control of the repository to an account that had been contributing to various data compression-related projects for several years. It was at this point that the backdoor was implanted in the project code.

Fortunately, the Potential Disaster Was Averted

As per Igor Kuznetsov, head of Kaspersky's Global Research and Analysis Team (GReAT), the vulnerability CVE-2024-3094 is considered as the largest scale attack that has happened in the Linux ecosystem history. Because it targeted the primary remote management tool for Linux servers on the internet which is  SSH servers.  

As this vulnerability was detected in the testing and rolling distributions in the short period of time, where the latest software packages are used. This results to the minimum damage to the linux users and so far no case of CVE-2024-3094 being actively exploited have been detected.

Staying Safe

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) advises that users who installed or updated the affected operating systems in March immediately roll back to XZ Utils 5.4.6 version and be on alert for any malicious activity. It is recommended to change the passwords in the case of a distribution where a weak version of XZ Utils has been installed. 

The Yara rule has been released to detect any infected systems by CVE-2024-3094 Vulnerability. 

Conclusion

The discovery of the XZ Utils backdoor provides a reminder to be vigilant in the open source software environment. This supply chain attack highlights the importance of strong security measures, elaborate code reviews, and regular distribution of security updates to provide shield against such vulnerabilities. Always staying informed and taking the necessary precautions, Linux users can mitigate the potential impact of this vulnerability to keep their systems safe.

Key points: Data collection, Protecting Children, and Awareness

Introduction

The evolution of technology has drastically changed over the period impacting mankind and their lifestyle. For every single smallest aspect, humans are reliable on the computers they have manufactured. The use of AI has almost hindered mankind, kids these days are more lethargic to work and write more sensibly on their own, but they are more likely interested in television, video games, mobile games, etc. School kids use AI just to complete their homework. Is it a good sign for the country’s future? The study suggests that Tools like ChatGPT is a threat to humans/a child’s potential to be creative and make original content requiring a human writer’s insight. Tools like ChatGPT can remove students’ artistic voices rather than using their unique writing style.

Does any of those browsers or search engines use your search history against you? or How do non-users tend to lose their private info on such a search engine?

Are there any safety measures that one’s the government of a particular country taking to protect their people’s rights?

Some of us might wonder how these two fancy-looking world merge and into, Arey they a boon or curse?

So here’s the top news getting flooded all over the world through the internet,

“Italian Agency impose strict measures on OpenAI’s ChatGPT”

Italy becomes the first Western European country to take serious measures about using Open AI ChatGPT. An Italian Data Protection agency named Garante has set mandates on ChatGPT. Garante has raised concerns about privacy violations and the inability to verify the age of users. Garate has also claimed that the AI ChatBot is violating the EU’s General Data Protection Regulation (GDPR). In a press release, Garante demanded OpenAI take necessary actions.

To begin with, Garante has demanded that OpenAI’s ChatGPT should increase its transparency and give a comprehensive statement about its data processing practices. OpenAI must specify between obtaining user consent for processing users’ data to train its AI model or may rely on a legitimate basis. OpenAI must maintain the privacy of users’ data.

In addition, ChatGPT should also take measures to prevent minors from accessing the technology at such an early stage of life, which could hinder their brain power. ChatGPT should add some age verification system to prevent minors from accessing explicit content. Moreover, Garante suggests that OpenAI should spread awareness among its users about their data being processed to train its AI model. Garante has set a deadline of April 30 for ChatGPT to complete the given tasks. Until then, its service should be banned in the country.

Child safety while surfing on ChatGpt

Italian agency demands age limitation to surf and an age verification method to exclude users under the age of 13, and parental authority should be required for users between the ages of 13 and 18. As this is a matter of security. Children might get exposed to explicit content invalidated to their age or explore illegitimate content. The AI chatbot doesn’t have the sense to determine which content is appropriate for the underage audience. Due to tools like chatbots, subjective things/information are already available to young students, leading to endangered irrespective of their future. As ChatGpt can hinder their potential and ability to create original and creative content for young minds. It is a threat motivation to humans’ motivation to write. Moreover, when students need time to think and analyze they get lethargic due to tools like ChatGPT, and the practice they need fades away.

Collection of User’s Data

According to some reports from the company’s privacy policy, OpenAI ChatGpt collects an assortment of additional data. The first two questions are for a free trial when a session starts. It asks for your Login, and SignUp through your Gmail account collects your IP address, browser type, and the data you put in the form of input, i.e. it collects data on the user’s interaction with the website, It also collects the user’s data like session time, cookies through third party may tend to sell it to an unspecified third party.

This snapshot shows that they have added a few things after Garante’s draft.

Conclusion

AI chatbot – Chatgpt is an advanced technology tool that makes work a little easier, but one surfing on such tools must stay aware of the information they are asking for. Such AI bots are trained to understand mankind, its job is to give a helping hand and not doltish. In case of this, some people tend to provide sensitive information unknowingly, young minds get exposed to explicit information. Such bots need to put some age limitations. Such innovations keep taking place, but it’s individuals’ responsibility what actions to be allowed to access their online connected device. Unlike the Italian Agency, which has taken some preventive measures to keep their user’s data safe, also looking at the adverse effect of such chatbots on a young mind.

Introduction

To combat the problem of annoying calls and SMS, telecom regulator TRAI has urged service providers to create a uniform digital platform in two months that will allow them to request, maintain, and withdraw customers’ approval for promotional calls and messages. In the initial stage, only subscribers will be able to initiate the process of registering their consent to receive promotional calls and SMS, and later, business entities will be able to contact customers to seek their consent to receive promotional messages, according to a statement issued by the Telecom Regulatory Authority of India (TRAI) on Saturday.

TRAI Directs Telecom Providers to Set Up Digital Platform

TRAI has now directed all access providers to develop and deploy the Digital Consent Acquisition (DCA) facility for creating a unified platform and process to digitally register customers’ consent across all service providers and principal entities. Consent is received and maintained under the current system by several key entities such as banks, other financial institutions, insurance firms, trading companies, business entities, real estate businesses, and so on.

The purpose, scope of consent, and the principal entity or brand name shall be clearly mentioned in the consent-seeking message sent over the short code,” according to the statement.

It stated that only approved online or app links, call-back numbers, and so on will be permitted to be used in consent-seeking communications.

TRAI issued guidelines to guarantee that all voice-based Telemarketers are brought under a single Distributed ledger technology (DLT) platform for more efficient monitoring of nuisance calls and unwanted communications. It also instructs operators to actively deploy AI/ML-based anti-phishing systems as well as to integrate tech solutions on the DLT platform to deal with malicious calls and texts.

TRAI has issued two separate Directions to Access Service Providers under TCCCPR-2018 (Telecom Commercial Communications Customer Preference Regulations) to ensure that all promotional messages are sent through Registered Telemarketers (RTMs) using approved Headers and Message Templates on Distributed Ledger Technologies (DLT) platform, and to stop misuse of Headers and Message Templates,” the regulator said in a statement.

Users can already block telemarketing calls and texts by texting 1909 from their registered mobile number. By dialing 1909, customers can opt out of getting advertising calls by activating the do not disturb (DND) feature.

Telecom providers operate DLT platforms, and businesses involved in sending bulk promotional or transactional SMS must register by providing their company information, including sender IDs and SMS templates.

According to the instructions, telecom companies will send consent-seeking messages using the common short code 127. The goal, extent of consent, and primary entity/brand name must be clearly stated in the consent-seeking message delivered via the shortcode.

TRAI stated that only whitelisted URLs/APKs (Android package kits file format)/OTT links/call back numbers, etc., shall be used in consent-seeking messages.

Telcos must “ensure that promotional messages are not transmitted by unregistered telemarketers or telemarketers using telephone numbers (10 digits numbers).” Telecom providers have been urged to act against all erring telemarketers in accordance with the applicable regulations and legal requirements.

Users can, however, refuse to receive any consent-seeking messages launched by any significant Telcos have been urged to create an SMS/IVR (interactive voice response)/online service for this purpose.

According to TRAI’s timeline, the consent-taking process by primary companies will begin on September 1.According to a nationwide survey conducted by a local circle, 66% of mobile users continue to receive three or more bothersome calls per day, the majority of which originate from personal cell numbers.

There are scams surfacing on the internet with new types of scams, like WhatsApp international call scams. The latest scam is targeting Delhi police, the scammers pretend to be police officials of Delhi and ask for the personal details of the users and the calling them from a 9-digit number.

A recent scam

A Twitter user reported receiving an automated call from +91 96681 9555, stating, “This call is from Delhi Police.” It went on to ask her to stay in the queue since some of her documents needed to be picked up. Then he said he is a sub-inspector at New Delhi’s Kirti Nagar police station. He then questioned if she had lately misplaced her Aadhaar card, PAN card, or ATM card, to which she replied ‘no’. The fraudster then claims to be a cop and asks her to validate the final four digits of her card because they have discovered a card with her name on it. And so many other people tweeted about this.

The scams are constantly increasing as earlier these scammers asked for account details and claimed to be Delhi police and used 9-digit numbers for scamming people.

TRAI’s new guidelines regarding the consent to receive any promotional calls and messages to telecommunication providers will be able to curb the scams.

The e- KYC is an essential requirement as e-KYC offers a more secure identity verification process in an increasingly digital age that uses biometric technologies to provide quick results.

Conclusion

The aim is to prevent unwanted calls and communications sent to customers via digital methods without their permission. Once this platform is implemented, an organization can only send promotional calls or messages with the customer’s explicit approval. Companies use a variety of methods to notify clients about their products, including phone calls, text messages, emails, and social media. Customers, however, are constantly assaulted with the same calls and messages as a result of this practice. With the constant increase in scams, the new guideline of TRAI will also curb the calling of Scams. digital KYC prevents SIM fraud and offers a more secure identity verification method.
