BGMI Relaunch

WhatsApp messages masquerading as an offer from Maruti Suzuki with links luring unsuspecting users with the promise of Maruti Suzuki 40th Anniversary Celebration presents, have been making the rounds on the app. If you receive such messages try to stay away from it, as it can be a scam.

The Research Wing of CyberPeace Foundation along with Autobot Infosec Private Limited have conducted a study based on a WhatsApp message that contained a link pretending to be a free gift offer from Maruti Suzuki which asks users to participate in a survey in order to get a chance to win a Maruti Baleno Sigma MT car.

Warning SignsThe campaign pretends to be an offer from Maruti Suzuki but is hosted on a third party domain instead of the official Maruti Suzuki website which makes it more suspicious.

The domain names associated with the campaign have been registered in very recent times.

Multiple redirections have been noticed between the links.

No reputed site would ask its users to share the campaign on WhatsApp.

The prize is kept really attractive to lure the laymen.

Grammatical mistakes have been noticed.

A congratulations message appears on the landing page with an attractive photo of Maruti Suzuki cars that asks users to participate in a quick survey in order to get a “Maruti Suzuki BALENO Sigma MT”. Also, the bottom of the page seems to appear like a comment section with public comments establishing the truthfulness of the offer.

The survey starts with some basic questions like Do you know Maruti Suzuki?, How old are you?, How do you think of Maruti Suzuki?, Are you male or female? Etc. Once the user answers the questions a “congratulatory message” is displayed.

On clicking the OK button users are given three attempts to win the prize. After completing all the attempts a message pops up that the user has won “Maruti Suzuki BALENO Sigma MT”. It then prompts the user to share the message on WhatsApp.

Strangely enough the user has to keep clicking the WhatsApp button until the progress bar completes. After clicking on the green ‘WhatsApp’ button multiple times it shows a section where an instruction has been given to complete registration in order to get the prize.

After clicking on the green ‘Complete registration’ button, it redirects the user to multiple advertisements web pages varying each time the user clicks on the button.

During the analysis the research team found a javascript code called hm.js was being executed in the background from the host hm[.]baidu[.]com which is a subdomain of Baidu and is used for Baidu Analytics, also known as Baidu Tongji. The important part is that Baidu is a Chinese multinational technology company specializing in Internet-related services, products and artificial intelligence, headquartered in Beijing’s Haidian district, China.To read the full report, please click (https://www.cyberpeace.org/CyberPeace/Repository/20210828Research-report-on-Maruti-Suzuki-40th-Anniversary-Celebration-free-gift-scam.pdf) here:

Conclusive Summary

1. The whole research activity was performed in a secured sandbox environment where the WhatsApp application was not installed. If any user opens the link from a device like smartphones where the WhatsApp application is installed, the sharing features on the site will open the Whatsapp application on the device to share the link.

2. The campaign collects browser and system information from the users.

3. Most of the domain names associated with the campaign have the registrant country as China.

4. Cybercriminals used Cloudflare technologies to mask the real IP addresses of the front-end domain names used in this Maruti Suzuki 40th Anniversary Celebration free gift campaign. But during the phases of investigation, the research team has identified a domain name that was requested in the background and has been traced as belonging to China.

CyberPeace Advisory

1. CyberPeace Foundation and Autobot Infosec recommend that people should avoid opening such messages sent via social platforms.

2. If at all, the user gets into this trap, it could lead to whole system compromise such as access to the microphone, Camera, Text Messages, Contacts, Pictures, Videos, Banking Applications, etc as well as financial losses.

3. Do not share confidential details like login credentials, banking information with such a type of scam.

4. Do not share or forward fake messages containing links without proper verification.

5. There is a need for International Cyber Cooperation between countries to bust the cybercriminal gangs running the fraud campaigns affecting individuals and organizations, to make Cyberspace resilient and peaceful.

Introduction

Recently the attackers employed the CVE-2017-0199 vulnerability in Microsoft Office to deliver a fileless form of the Remcos RAT. The Remcos RAT makes the attacker have full control of the systems that have been infected by this malware. This research will give a detailed technical description of the identified vulnerability, attack vector, and tactics together with the practical steps to counter the identified risks.

The Targeted Malware: Remcos RAT

Remcos RAT (Remote Control & Surveillance) is a commercially available remote access tool designed for legitimate administrative use. However, it has been widely adopted by cybercriminals for its stealth and extensive control capabilities, enabling:

• System control and monitoring
• Keylogging
• Data exfiltration
• Execution of arbitrary commands

The fileless variant utilised in this campaign makes detection even more challenging by running entirely in system memory, leaving minimal forensic traces.

Attack Vector: Phishing with Malicious Excel Attachments

The phishing email will be sent which appears as legitimate business communication, such as a purchase order or invoice. This email contains an Excel attachment that is weaponized to exploit the CVE-2017-0199 vulnerability.

Technical Analysis: CVE-2017-0199 Exploitation

Vulnerability Assessment

• CVE-2017-0199 is a Remote Code Execution (RCE) vulnerability in Microsoft Office which uses Object Linking and Embedding (OLE) objects.
• Affected Components:some text
  • Microsoft Word
  • Microsoft Excel
  • WordPad
• CVSS Score: 7.8 (High Severity)

Mechanism of Exploitation

The vulnerability enables attackers to craft a malicious document when opened, it fetches and executes an external payload via an HTML Application (HTA) file. The execution process occurs without requiring user interaction beyond opening the document.

Detailed Exploitation Steps

1. Phishing Email and Malicious Document some text
   • The email contains an Excel file designed to make use of CVE-2017-0199.
   • When the email gets opened, the document automatically connects to a remote server (e.g., 192.3.220[.]22) to download an HTA file (cookienetbookinetcache.hta).
2. Execution via mshta.exe some text
   • The downloaded HTA file is executed using mshta.exe, a legitimate Windows process for running HTML Applications.
   • This execution is seamless and does not prompt the user, making the attack stealthy.
3. Multi-Layer Obfuscation some text
   • The HTA file is wrapped in several layers of scripting, including: some text
     • JavaScript
     • VBScript
     • PowerShell
   • This obfuscation helps evade static analysis by traditional antivirus solutions.
4. Fileless Payload Deployment some text
   • The downloaded executable leverages process hollowing to inject malicious code into legitimate system processes.
   • The Remcos RAT payload is loaded directly into memory, avoiding the creation of files on disk.

Fileless Malware Techniques

1. Process Hollowing
The attack replaces the memory of a legitimate process (e.g., explorer.exe) with the malicious Remcos RAT payload. This allows the malware to:

• Evade detection by blending into normal system activity.
• Run with the privileges of the hijacked process.

2. Anti-Analysis Techniques

• Anti-Debugging: Detects the presence of debugging tools and terminates malicious processes if found.
• Anti-VM and Sandbox Evasion: Ensures execution only on real systems to avoid detection during security analysis.

3. In-Memory Execution

• By running entirely in system memory, the malware avoids leaving artifacts on the disk, making forensic analysis and detection more challenging.

Capabilities of Remcos RAT

Once deployed, Remcos RAT provides attackers with a comprehensive suite of functionalities, including:

• Data Exfiltration: some text
  • Stealing system information, files, and credentials.
• Remote Execution: some text
  • Running arbitrary commands, scripts, and additional payloads.
• Surveillance: some text
  • Enabling the camera and microphone.
  • Capturing screen activity and clipboard contents.
• System Manipulation: some text
  • Modifying Windows Registry entries.
  • Controlling system services and processes.
  • Disabling user input devices (keyboard and mouse).

Advanced Phishing Techniques in Parallel Campaigns

1. DocuSign Abuse
Attackers exploit legitimate DocuSign APIs to create authentic-looking phishing invoices. These invoices can trick users into authorising payments or signing malicious documents, bypassing traditional email security systems.

2. ZIP File Concatenation
By appending multiple ZIP archives into a single file, attackers exploit inconsistencies in how different tools handle these files. This allows them to embed malware that evades detection by certain archive managers.

Broader Implications of Fileless Malware

Fileless malware like Remcos RAT poses significant challenges:

• Detection Difficulties: Traditional signature-based antivirus systems struggle to detect fileless malware, as there are no static files to scan.
• Forensic Limitations: The lack of disk artifacts complicates post-incident analysis, making it harder to trace the attack's origin and scope.
• Increased Sophistication: These campaigns demonstrate the growing technical prowess of cybercriminals, leveraging legitimate tools and services for malicious purposes.

Mitigation Strategies

1. Patch Management some text
   • It is important to regularly update software to address known vulnerabilities like CVE-2017-0199. Microsoft released a patch for this vulnerability in April 2017.
2. Advanced Email Security some text
   • It is important to implement email filtering solutions that can detect phishing attempts, even those using legitimate services like DocuSign.
3. Endpoint Detection and Response (EDR)some text
   • Always use EDR solutions to monitor for suspicious behavior, such as unauthorized use of mshta.exe or process hollowing.
4. User Awareness and Training some text
   • Educate users about phishing techniques and the risks of opening unexpected attachments.
5. Behavioral Analysis some text
   • Deploy security solutions capable of detecting anomalous activity, even if no malicious files are present.

Conclusion

The attack via CVE-2017-0199 further led to the injection of a new fileless variant of Remcos RAT, proving how threats are getting more and more sophisticated. Thanks to the improved obfuscation and the lack of files, the attackers eliminate all traditional antiviral protection and gain full control over the infected computers. It is real and organisations have to make sure that they apply patches on time, that they build better technologies for detection and that the users themselves are more wary of the threats.

Introduction

The Supreme Court of India recently ruled that telecom companies cannot be debarred from reissuing the deactivated numbers to a new subscriber. Notably, such reallocation of deactivated numbers is allowed only after the expiration of the period of 90 days. The Apex Court of India also mentioned that it is the responsibility of the user to delete their associated data with their number or any WhatsApp account data to ensure privacy. The  Centre has recently also blocked 22 apps which were part of unlawful operations including betting and money laundering. Meanwhile, in the digital landscape, the Intervention of legislature and judiciary is playing a key role in framing policies or coming up with guidelines advocating for a true cyber-safe India.  The government initiatives are encouraging the responsible use of technologies and Internet-availed services. 

Supreme Court stated that  telecom companies cannot be barred from reissuing deactivated numbers

Taking note of a petition before the Supreme Court of India, seeking direction from the Telecom Regulatory Authority of India (TRAI) to instruct mobile service providers to stop issuing deactivated mobile numbers, the Apex Court dismissed it by stating that mobile service providers in India are allowed to allocate the deactivated numbers to new users or subscribers but only after 90 days from the deactivation of the number. 

A concern of Breach of Confidential Data

The Court further stated, “It is for the earlier subscriber to take adequate steps to ensure that privacy is maintained.” stating that it is the responsibility of the user to delete their WhatsApp account attached to the previous phone number and erase their data. The Court further added that users need to be aware of the Supreme Court ruling that once the number is deactivated for non-use and disconnection, it can not be reallocated before the expiry of the 90-day period of such deactivation. However, after the allotted time passes, such reallocation of numbers to a new user is allowed.   

MEITY issued blocking orders against 22 illegal betting apps & websites

The government of India has been very critical in safeguarding Indian cyberspace by banning and blocking various websites and apps that have been operating illegally by scamming/dupping people of huge sums of money and also committing cyber crimes like data breaches. In recent developments, the Ministry of Electronic and Information Technology (Meity), on November 5, 2023, banned 22 apps including Mahadev Book and Reddyannaprestopro. The Centre has taken this decision on recommendations from the Enforcement Directorate (ED). ED raids on the Mahadev book app in Chattisgarh also revealed unlawful operations. This investigation has been underway for the past few months by the ED.

Applicable laws to prevent money laundering and the power of government to block such websites and apps

On the other hand, the Prevention of Money Laundering Act (PMLA) 2002 is a legislation already in place which aims to prevent and prosecute cases of money laundering. The government also has the power to block or recommend shutting down websites and apps under section 69A of the Information and Technology Act, 2000, under some specific condition as enumerated in the same.

Conclusion

In the evolving digital landscape, cyberspace covers several aspects while certain regulations or guidelines are required for smooth and secure functioning.  We sometimes change our phone numbers or deactivate them, hence, it is significantly important to delete the data associated with the phone number or any such social media account data attached to it. Hence, such a number is eligible for reallocation to a new or early subscriber after the expiration of a period of 90 days from such deactivation. On the other hand, the centre has also blocked the websites or apps that were found to be part of illegal operations including betting and money laundering. Users have also been advised not to misuse the Internet-availed services. Hence, trying to create a lawful and safe Internet environment for all.
