#FactCheck - AI-Generated Video Falsely Shared as ‘Multi-Hooded Snake’ Sighting in Vrindavan

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.

AI and other technologies are advancing rapidly. This has ensured the rapid spread of information, and even misinformation. LLMs have their advantages, but they also come with drawbacks, such as confident but inaccurate responses due to limitations in their training data. The evidence-driven retrieval systems aim to address this issue by using and incorporating factual information during response generation to prevent hallucination and retrieve accurate responses.

What is Retrieval-Augmented Response Generation?

Evidence-driven Retrieval Augmented Generation (or RAG) is an AI framework that improves the accuracy and reliability of large language models (LLMs) by grounding them in external knowledge bases. RAG systems combine the generative power of LLMs with a dynamic information retrieval mechanism. The standard AI models rely solely on pre-trained knowledge and pattern recognition to generate text. RAG pulls in credible, up-to-date information from various sources during the response generation process. RAG integrates real-time evidence retrieval with AI-based responses, combining large-scale data with reliable sources to combat misinformation. It follows the pattern of:

• Query Identification: When misinformation is detected or a query is raised.
• Evidence Retrieval: The AI searches databases for relevant, credible evidence to support or refute the claim.
• Response Generation: Using the evidence, the system generates a fact-based response that addresses the claim.

How is Evidence-Driven RAG the key to Fighting Misinformation?

• RAG systems can integrate the latest data, providing information on recent scientific discoveries.
• The retrieval mechanism allows RAG systems to pull specific, relevant information for each query, tailoring the response to a particular user’s needs.
• RAG systems can provide sources for their information, enhancing accountability and allowing users to verify claims.
• Especially for those requiring specific or specialised knowledge, RAG systems can excel where traditional models might struggle.
• By accessing a diverse range of up-to-date sources, RAG systems may offer more balanced viewpoints, unlike traditional LLMs.

Policy Implications and the Role of Regulation

With its potential to enhance content accuracy, RAG also intersects with important regulatory considerations. India has one of the largest internet user bases globally, and the challenges of managing misinformation are particularly pronounced.

• Indian regulators, such as MeitY, play a key role in guiding technology regulation. Similar to the EU's Digital Services Act, the Information Technology (Intermediary Guidelines and Digital Media Ethics Code) Rules, 2021, mandate platforms to publish compliance reports detailing actions against misinformation. Integrating RAG systems can help ensure accurate, legally accountable content moderation. 
• Collaboration among companies, policymakers, and academia is crucial for RAG adaptation, addressing local languages and cultural nuances while safeguarding free expression. 
• Ethical considerations are vital to prevent social unrest, requiring transparency in RAG operations, including evidence retrieval and content classification. This balance can create a safer online environment while curbing misinformation.

Challenges and Limitations of RAG

While RAG holds significant promise, it has its challenges and limitations.

• Ensuring that RAG systems retrieve evidence only from trusted and credible sources is a key challenge. 
• For RAG to be effective, users must trust the system. Sceptics of content moderation may show resistance to accepting the system’s responses. 
• Generating a response too quickly may compromise the quality of the evidence while taking too long can allow misinformation to spread unchecked.

Conclusion

Evidence-driven retrieval systems, such as Retrieval-Augmented Generation, represent a pivotal advancement in the ongoing battle against misinformation. By integrating real-time data and credible sources into AI-generated responses, RAG enhances the reliability and transparency of online content moderation. It addresses the limitations of traditional AI models and aligns with regulatory frameworks aimed at maintaining digital accountability, as seen in India and globally. However, the successful deployment of RAG requires overcoming challenges related to source credibility, user trust, and response efficiency. Collaboration between technology providers, policymakers, and academic experts can foster the navigation of these to create a safer and more accurate online environment. As digital landscapes evolve, RAG systems offer a promising path forward, ensuring that technological progress is matched by a commitment to truth and informed discourse.

Introduction

The CID of Jharkhand Police has uncovered a network of around 8000 bank accounts engaged in cyber fraud across the state, with a focus on Deoghar district, revealing a surprising 25% concentration of fraudulent accounts. In a recent meeting with bank officials, the CID shared compiled data, with 20% of the identified accounts traced to State Bank of India branches. This revelation, surpassing even Jamtara's cyber fraud reputation, prompts questions about the extent of cybercrime in Jharkhand. Under Director General Anurag Gupta's leadership, the CID has registered 90 cases, apprehended 468 individuals, and seized 1635 SIM cards and 1107 mobile phones through the Prakharna portal to combat cybercrime. 

This shocking revelation by, Jharkhand Police's Criminal Investigation Department (CID) has built a comprehensive database comprising information on about 8000 bank accounts tied to cyber fraud operations in the state. This vital information has aided in the launch of investigations to identify the account holders implicated in these illegal actions. Furthermore, the CID shared this information with bank officials at a meeting on January 12 to speed up the identification process.

Background of the Investigation

The CID shared the collated material with bank officials in a meeting on 12 January 2024 to expedite the identification process. A stunning 2000 of the 8000 bank accounts under investigation are in the Deoghar district alone, with 20 per cent of these accounts connected to various State Bank of India branches. The discovery of 8000 bank accounts related to cybercrime in Jharkhand is shocking and disturbing. Surprisingly, Deoghar district has exceeded even Jamtara, which was famous for cybercrime, accounting for around 25% of the discovered bogus accounts in the state.

As per the information provided by the CID Crime Branch, it has been found that most of the accounts were opened in banks, are currently under investigation and around 2000 have been blocked by the investigating agencies.

Recovery Process

During the investigation, it was found out that most of these accounts were running on rent, the cyber criminals opened them by taking fake phone numbers along with Aadhar cards and identity cards from people in return these people(account holders) will get a fixed amount every month. 

The CID has been unrelenting in its pursuit of cybercriminals. Police have recorded 90 cases and captured 468 people involved in cyber fraud using the Prakharna site. 1635 SIM Cards and 1107 mobile phones were confiscated by police officials during raids in various cities.

The Crime Branch has revealed the names of the cities where accounts are opened

1. Deoghar 2500
2. Dhanbad 1183
3. Ranchi 959
4. Bokaro 716
5. Giridih 707
6. Jamshedpur 584
7. Hazaribagh 526
8. Dumka 475

Impact on the Financial Institutions and Individuals

These cyber scams significantly influence financial organisations and individuals; let us investigate the implications.

• Victims: Cybercrime victims have significant financial setbacks, which can lead to long-term financial insecurity. In addition, people frequently suffer mental pain as a result of the breach of personal information, which causes worry, fear, and a lack of faith in the digital financial system. One of the most difficult problems for victims is the recovery process, which includes retrieving lost cash and repairing the harm caused by the cyberattack. Individuals will find this approach time-consuming and difficult, in a lot of cases people are unaware of where and when to approach and seek help. Hence, awareness about cybercrimes and a reporting mechanism are necessary to guide victims through the recovery process, aiding them in retrieving lost assets and repairing the harm inflicted by cyberattacks.

• Financial Institutions: Financial institutions face direct consequences when they incur significant losses due to cyber financial fraud. Unauthorised account access, fraudulent transactions, and the compromise of client data result in immediate cash losses and costs associated with investigating and mitigating the breach's impact. Such assaults degrade the reputation of financial organisations, undermine trust, erode customer confidence, and result in the loss of potential clients. 

• Future Implications and Solutions: Recently, the CID discovered a sophisticated cyber fraud network in Jharkhand. As a result, it is critical to assess the possible long-term repercussions of such discoveries and propose proactive ways to improve cybersecurity. The CID's findings are expected to increase awareness of the ongoing threat of cyber fraud to both people and organisations. Given the current state of cyber dangers, it is critical to implement rigorous safeguards and impose heavy punishments on cyber offenders. Government organisations and regulatory bodies should also adapt their present cybersecurity strategies to address the problems posed by modern cybercrime.

Solution and Preventive Measures

Several solutions can help combat the growing nature of cybercrime. The first and foremost step is to enhance cybersecurity education at all levels, including:

• Individual Level: To improve cybersecurity for individuals, raising awareness across all age groups is crucial. This can only be done by knowing the potential threats by following the best online practices, following cyber hygiene, and educating people to safeguard themselves against financial frauds such as phishing, smishing etc.
• Multi-Layered Authentication: Encouraging individuals to enable MFA for their online accounts adds an extra layer of security by requiring additional verification beyond passwords. 
• Continuous monitoring and incident Response:  By continuously monitoring their financial transactions and regularly reviewing the online statements and transaction history, ensure that everyday transactions are aligned with your expenditures, and set up the accounts alert for transactions exceeding a specified amount for usual activity.   
• Report Suspicious Activity: If you see any fraudulent transactions or activity, contact your bank or financial institution immediately; they will lead you through investigating and resolving the problem. The victim must supply the necessary paperwork to support your claim.

How to reduce the risks

• Freeze compromised accounts: If you think that some of your accounts have been compromised, call the bank immediately and request that the account be frozen or temporarily suspended, preventing further unauthorised truncations

• Update passwords: Update and change your passwords for all the financial accounts, emails, and online banking accounts regularly, if you suspect any unauthorised access, report it immediately  and always enable MFA that adds an extra layer of protection to your accounts.

Conclusion

The CID's finding of a cyber fraud network in Jharkhand is a stark reminder of the ever-changing nature of cybersecurity threats. Cyber security measures are necessary to prevent such activities and protect individuals and institutions from being targeted against cyber fraud.
