Cyber criminals target internet users with “Maruti Suzuki 40th Anniversary Celebration” free gift scam

Executive Summary:

A recent claim going around on social media that a child created sand sculptures of cricket legend Mahendra Singh Dhoni, has been proven false by the CyberPeace Research Team. The team discovered that the images were actually produced using an AI tool. Evident from the unusual details like extra fingers and unnatural characteristics in the sculptures, the Research Team discerned the likelihood of artificial creation. This suspicion was further substantiated by AI detection tools. This incident underscores the need to fact-check information before posting, as misinformation can quickly go viral on social media. It is advised everyone to carefully assess content to stop the spread of false information.

Claims:

The claim is that the photographs published on social media show sand sculptures of cricketer Mahendra Singh Dhoni made by a child.

Fact Check:

Upon receiving the posts, we carefully examined the images. The collage of 4 pictures has many anomalies which are the clear sign of AI generated images.

‍

In the first image the left  hand of the sand sculpture has 6 fingers and in the word INDIA, ‘A’ is not properly aligned i.e not in the same line as other letters. In the second image, the finger of the boy is missing and the sand sculpture has 4 fingers in its front foot and has 3 legs. In the third image the slipper of the boy is not visible whereas some part of the slipper is visible, and in the fourth image the hand of the boy is not looking like a hand. These are some of the major discrepancies clearly visible in the images.

We then checked using an AI Image detection tool named ‘Hive’ image detection, Hive detected the image as 100.0% AI generated.

We then checked it in another AI image detection named ContentAtScale AI image detection, and it found to be 98% AI generated.

‍

From this we concluded that the Image is AI generated and has no connection with the claim made in the viral social media posts. We have also previously debunked AI Generated artwork of sand sculpture of Indian Cricketer Virat Kohli which had the same types of anomalies as those seen in this case.

Conclusion:

Taking into consideration the distortions spotted in the images and the result of AI detection tools, it can be concluded that the claim of the pictures representing the child's sand sculptures of cricketer Mahendra Singh Dhoni is false. The pictures are created with Artificial Intelligence. It is important to check and authenticate the content before posting it to social media websites.

• Claim: The frame of pictures shared on social media contains child's sand sculptures of cricket player Mahendra Singh Dhoni.
• Claimed on: X (formerly known as Twitter), Instagram, Facebook, YouTube
• Fact Check: Fake & Misleading

What is Juice Jacking?

We all use different devices during the day, but they converge to a common point when the battery runs out, the cables and adaptors we use to charge the devices are daily necessities for everyone. These cables and adaptors have access to the only port in the phones and hence are used for juice-jacking attacks. Juice jacking is when someone installs malware or spyware software in your device using an unknown charging port or cable.

How does juice jacking work?

We all use phones and gadgets, like I-phones, smartphones, Android devices: and smartwatches, to simplify our lives. But one thing common in it is the charging cables or USB ports, as the data and power supply pass through the same port/cable.

This is potentially a problem with devastating consequences. When your phone connects to another device, it pairs with it (ports/cables) and establishes a trusted relationship. That means the devices can exchange data. During the charging process, the USB cord opens a path into your device that a cybercriminal can exploit.

There is a default setting in the phones where data transfer is disabled, and the connections which provide the power are visible at the end. For example, in the latest models, when you plug your device into a new port or a computer, a question is pooped asking whether the device is trusted. The device owner cannot see what the USB port connects to in case of juice jacking. So, if you plug in your phone and someone checks on the other end, they may be able to transfer data between your device and theirs, thus leading to a data breach.

A leading airline was recently hacked into, which caused delayed flights across the country. When investigated, it was found that malware was planted in the system by using a USB port, which allowed the hackers access to critical data to launch their malware attack.

FBI’s Advisory

Federal Bureau of Investigation and other Interpol agencies have been very critical of cybercriminals. Inter-agency cooperation has improved the pace of investigation and chances of apprehending criminals. In a tweet by the FBI, the issue of Juice Jakcking was addressed, and public places like airports, railways stations, shopping malls etc., are pinpointed places where such attacks have been seen and reported. These places offer easy access to charging points for various devices, which are the main targets for bad actors. The FBI advises people not to use the charging points and cables at airports, railways stations and hotels and also lays emphasis upon the importance of carrying your own cable and charger.

Tips to protect yourself from juice jacking

There are a few simple and effective tips to keep your smart devices smart, such as –

• Avoid using public charging stations: The best way to protect yourself and your devices is to avoid public charging stations it’s always a good habit to charge your phones in your car, at home, and in offices when not in use.
• Using a wall outlet is a safer option: If it’s too urgent for you to use a public station, try to use wall outlets rather than poles because data can’t get easily transferred.
• Use other methods/modes of charging: If you are travelling, carrying a power bank is always safe, as it is easy to carry.
• Software security: – It’s always advised to update your phone’s software regularly. Once connected to the charging station, lock your device. This will prevent it from syncing or transferring data.
• Enable Airplane mode while charging: If you need to charge your phone from an unknown source in a public area, it is advisable to put the phone on airplane mode or switch it off to prevent anyone from gaining access to your device through any open network.

However, many mobile phones (including iPhones) turn on automatically when connected to power. As a result, your mileage may vary. This is an effective safeguard if your phone does not turn on automatically when connected to power.

Conclusion

As of present, juice-jacking attacks are less frequent. While not the most common type of attack today, the number of occurrences is expected to rise as smartphone gadget usage and penetration are rising across the globe. Our cyber safety and security are in our hands, and hence protecting them is our paramount digital duty. Always remember we see no harm in charging ports, but that doesn’t mean that the possibility of a threat can be ruled out completely. With the increased use of ports for charging, earphones, and data transfer, such crimes will continue and evolve with time. Thus, it is essential to counter these attacks by sharing knowledge and awareness of such crimes and reporting them to competent authorities to eradicate the menace of cybercriminals from our digital ecosystem.

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.
