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.

Introduction

The ongoing armed conflict between Israel and Hamas/ Palestine is in the news all across the world. The latest conflict was triggered by unprecedented attacks against Israel by Hamas militants on October 7, killing thousands of people. Israel has launched a massive counter-offensive against the Islamic militant group. Amid the war, the bad information and propaganda spreading on various social media platforms, tech researchers have detected a network of 67 accounts that posted false content about the war and received millions of views. The ‘European Commission’ has sent a letter to Elon Musk, directing them to remove illegal content and disinformation; otherwise, penalties can be imposed. The European Commission has formally requested information from several social media giants on their handling of content related to the Israel-Hamas war. This widespread disinformation impacts and triggers the nature of war and also impacts the world and affects the goodwill of the citizens. The bad group, in this way, weaponise the information and fuels online hate activity, terrorism and extremism, flooding political polarisation with hateful content on social media. Online misinformation about the war is inciting extremism, violence, hate and different propaganda-based ideologies. The online information environment surrounding this conflict is being flooded with disinformation and misinformation, which amplifies the nature of war and too many fake narratives and videos are flooded on social media platforms.

Response of social media platforms 

As there is a proliferation of online misinformation and violent content surrounding the war, It imposes a question on social media companies in terms of content moderation and other policy shifts.  It is notable that Instagram, Facebook and X(Formerly Twitter) all have certain features in place giving users the ability to decide what content they want to view. They also allow for limiting the potentially sensitive content from being displayed in search results.

The experts say that It is of paramount importance to get a sort of control in this regard and define what is permissible online and what is not, Hence, what is required is expertise to determine the situation, and most importantly, It requires robust content moderation policies. 

During wartime, people who are aggrieved or provoked are often targeted by this internet disinformation that blends ideological beliefs and spreads conspiracy theories and hatred. This is not a new phenomenon, it is often observed that disinformation-spreading groups emerged and became active during such war and emergency times and spread disinformation and propaganda-based ideologies and influence the society at large by misrepresenting the facts and planted stories. Social media has made it easier to post user-generated content without properly moderating it. However, it is a shared responsibility of tech companies, users, government guidelines and policies to collectively define and follow certain mechanisms to fight against disinformation and misinformation.  

Digital Services Act (DSA)

The newly enacted EU law, i.e. Digital Services Act, pushes various larger online platforms to prevent posts containing illegal content and also puts limits on targeted advertising. DSA enables to challenge the of illegal online content and also poses requirements to prevent misinformation and disinformation and ensure more transparency over what the users see on the platforms. Rules under the DSA cover everything from content moderation & user privacy to transparency in operations. DSA is a landmark EU legislation moderating online platforms.  Large tech platforms are now subject to content-related regulation under this new EU law ‘The Digital Services Act’, which also requires them to prevent the spread of misinformation and disinformation and overall ensure a safer online environment.

Indian Scenario

The Indian government introduced the Intermediary Guidelines (Intermediary Guidelines and Digital Media Ethics Code) Rules, updated in 2023 which talks about the establishment of a "fact check unit" to identify false or misleading online content. Digital Personal Data Protection, 2023 has also been enacted which aims to protect personal data. The upcoming Digital India bill is also proposed to be tabled in the parliament, this act will replace the current Information & Technology Act, of 2000. The upcoming Digital India bill can be seen as future-ready legislation to strengthen India’s current cybersecurity posture. It will comprehensively deal with the aspects of ensuring privacy, data protection, and fighting growing cyber crimes in the evolving digital landscape and ensuring a safe digital environment. Certain other entities including civil societies are also actively engaged in fighting misinformation and spreading awareness for safe and responsible use of the Internet. 

Conclusion:

The widespread disinformation and misinformation content amid the Israel-Hamas war showcases how user-generated content on social media shows you the illusion of reality. There is widespread misinformation, misleading content or posts on social media platforms, and misuse of new advanced AI technologies that even make it easier for bad actors to create synthetic media content. It is also notable that social media has connected us like never before. Social media is a great platform with billions of active social media users around the globe, it offers various conveniences and opportunities to individuals and businesses. It is just certain aspects that require the attention of all of us to prevent the bad use of social media. The social media platforms and regulatory authorities need to be vigilant and active in clearly defining and improving the policies for content regulation and safe and responsible use of social media which can effectively combat and curtail the bad actors from misusing social media for their bad motives. As a user, it's the responsibility of users to exercise certain duties and promote responsible use of social media. With the increasing penetration of social media and the internet, misinformation is rampant all across the world and remains a global issue which needs to be addressed properly by implementing strict policies and adopting best practices to fight the misinformation. Users are encouraged to flag and report misinformative or misleading content on social media and should always verify it from authentic sources. Hence creating a safer Internet environment for everyone.

Introduction

The Ministry of Electronics and Information Technology (MeitY) recently issued the “Email Policy of Government of India, 2024.” It is an updated email policy for central government employees, requiring the exclusive use of official government emails managed by the National Informatics Centre (NIC) for public duties. The policy replaces 2015 guidelines and prohibits government employees, contractors, and consultants from using their official email addresses on social media or other websites unless authorised for official functions. The policy aims to reinforce cybersecurity measures and protocols, maintain secure communications, and ensure compliance across departments. It is not legally binding, but its gazette notification ensures compliance and maintains cyber resilience in communications. The updated policy is also aligned with the newly enacted Digital Personal Data Protection Act, 2023.

Brief Highlights of Email Policy of Government of India, 2024

• The Email Policy of the Government of India, 2024 is divided into three parts namely, Part I: Introduction, Part II: Terms of Use, Part III: Functions, duties and Responsibilities, and with an annexe attached to it defining the meaning of certain organisation types in relation to this policy.
• The policy direct to not use NICeMail address for registering on any social media or other websites or mobile applications, save for the performance of official duties or with due authorisation from the authority competent.
• Under this new policy, “core use organisations” (central government departments and other government-controlled entities that do not provide goods or services on commercial terms) and its users shall use only NICeMail for official purposes. 

• However, where the Core Use Organisation has an office or establishment outside India, to ensure availability of local communication channels under exigent circumstances may use alternative email services hosted outside India with all due approval.
• Core Use Organisations, including those dealing with national security, have their own independent email servers and can continue operating their independent email servers provided the servers are hosted in India. They should also consider migrating their email services to NICeMail Services for security and uniform policy enforcement.
• The policy also requires departments that currently use @gov.in or @nic.in to instead migrate to @departmentname.gov.in mail domains so that information sanctity and integrity can be maintained when officials are transferred from one department/ministry to another, and so that the ministry/department doesn’t lose access to the official communication. For this, the department or ministry in question must register the domain name with NIC. For instance, MeitY has registered the mail domain @meity.gov.in. The policy gives government departments six months time period complete this migration.
• The policy also makes distinction between (1) Organisation-linked email addresses and (2) Service-linked email addresses. The policy in respect of “organisation-linked email addresses” is laid down in paragraphs 5.3.2(a) and 5.4 to 5.6.3. And the policy in respect of “service-linked email addresses” is laid down in paragraphs 5.3.2(b) and 5.7 to 5.7.2 under the official document of said policy. 

• Further, the new policy includes specific directives on separating the email addresses of regular government employees from those of contractors or consultants to improve operational clarity.

CyberPeace Policy Outlook 

The revised Email Policy of the Government of India reflects the government’s proactive response to countering the evolving cybersecurity challenges and aims to maintain cyber resilience across the government department’s email communications. The policy represents a significant step towards securing inter government and intra-government communications. We as a cybersecurity expert organisation emphasise the importance of protecting sensitive data against cyber threats, particularly in a world increasingly targeted by sophisticated phishing and malware attacks, and we advocate for safe and secure online communication and information exchange. Email communications hold sensitive information and therefore require robust policies and mechanisms in place to safeguard the communications and ensure that sensitive data is shielded through regulated and secure email usage with technical capabilities for safe use. The proactive step taken by MeitY is commendable and aligned with securing governmental communication channels.
