Empowering Youth for a Secure Digital Future: AI Upskilling as the Key to Resilience

Executive Summary:

New Linux malware has been discovered by a cybersecurity firm Volexity, and this new strain of malware is being referred to as DISGOMOJI. A Pakistan-based threat actor alias ‘UTA0137’ has been identified as having espionage aims, with its primary focus on Indian government entities.  Like other common forms of backdoors and botnets involved in different types of cyberattacks, DISGOMOJI, the malware  allows the use of commands to capture screenshots, search for files to steal, spread additional payloads, and transfer files. DISGOMOJI  uses Discord (messaging service)  for Command & Control (C2)  and uses emojis  for C2 communication. This malware targets Linux operating systems.

The DISCOMOJI Malware:  

• The DISGOMOJI malware opens a specific channel in a Discord server and every new channel corresponds to a new victim. This means that the attacker can communicate with the victim one at a time.

• This particular malware connects with the attacker-controlled Discord server using Emoji, a form of relay protocol. The attacker provides unique emojis as instructions, and the malware uses emojis as a feedback to the subsequent command status.

• For instance, the ‘camera with flash’ emoji is used to screenshots the device of the victim or to steal, the ‘fox’ emoji cracks all Firefox profiles, and the ‘skull’ emoji kills the malware process.

• This C2 communication is done using emojis to ensure messaging between infected contacts, and it is almost impossible for Discord to shut down the malware as it can always change the account details of Discord it is using once the maliciou server is blocked.

• The malware also has capabilities aside from the emoji-based C2 such as network probing, tunneling, and data theft that are needed to help the UTA0137 threat actor in achieving its espionage goals.

Specific emojis used for different commands by UTA0137:

• Camera with Flash (📸): Captures a picture of the target device’s screen as per the victim’s directions.

• Backhand Index Pointing Down (👇): Extracts files from the targeted device and sends them to the command channel in the form of attachments.

• Backhand Index Pointing Right (👉): This process involves sending a file found on the victim’s device to another web-hosted file storage service known as Oshi or oshi[. ]at.

• Backhand Index Pointing Left (👈): Sends a file from the victim’s device to transfer[. ]sh, which is an online service for sharing files on the Internet.

• Fire (🔥): Finds and transmits all files with certain extensions that exist on the victim’s device, such as *. txt, *. doc, *. xls, *. pdf, *. ppt, *. rtf, *. log, *. cfg, *. dat, *. db, *. mdb, *. odb, *. sql, *. json, *. xml, *. php, *. asp, *. pl, *. sh, *. py, *. ino, *. cpp, *. java,

• Fox (🦊): This works by compressing all Firefox related profiles in the affected device. 

• Skull (💀): Kills the malware process in windows using ‘os. Exit()’

• Man Running (🏃‍♂️):  Execute a command on a victim’s device. This command receives an argument, which is the command to execute.

• Index Pointing up (👆) : Upload a file to the victim's device. The file to upload is attached along with this emoji

Analysis:   

The analysis was carried out for one of the indicator of compromised SHA-256 hash file-  C981aa1f05adf030bacffc0e279cf9dc93cef877f7bce33ee27e9296363cf002.

It is found that most of the vendors have marked the file as trojan in virustotal and the graph explains the malicious nature of the contacted domains and IPs.

‍

Discord & C2 Communication  for UTA0137:

• Stealthiness: Discord is a well-known messaging platform used for different purposes, which means that sending any messages or files on the server should not attract suspicion. Such stealthiness makes it possible for UTA0137 to remain dormant for greater periods before launching an attack.

• Customization: UTA0137 connected to Discord is able to create specific channels for distinct victims on the server. Such a framework allows the attackers to communicate with each of the victims individually to make a process more accurate and efficient.

• Emoji-based protocol: For C2 communication, emojis really complicates the attempt that Discord might make to interfere with the operations of the malware. In case the malicious server gets banned, malware could easily be recovered, especially by using the Discord credentials from the C2 server.

• Persistence: The malware, as stated above, has the ability to perpetually exist to hack the system and withstand rebooting of systems so that the virus can continue to operate without being detected by the owner of the hacked system.

• Advanced capabilities: Other features of DISGOMOJI are the Network Map using Nmap scanner, network tunneling through Chisel and Ligolo and Data Exfiltration by File Sharing services. These capabilities thus help in aiding the espionage goals of UTA0137.

• Social engineering: The virus and the trojan can show the pop-up windows and prompt messages, for example the fake update for firefox and similar applications, where the user can be tricked into inputting the password.

• Dynamic credential fetching: The malware does not write the hardcoded values of the credentials in order to connect it to the discord server. This also inconveniences analysts as they are unable to easily locate the position of the C2 server.

• Bogus informational and error messages: They never show any real information or errors because they do not want one to decipher the malicious behavior easily.

Recommendations to mitigate the risk of UTA0137:

• Regularly Update Software and Firmware: It is essential to regularly update all the application software and firmware of different devices, particularly, routers, to prevent hackers from exploiting the discovered and disclosed flaws. This includes fixing bugs such as CVE-2024-3080 and CVE-2024-3912 on ASUS routers, which basically entails solving a set of problems.

• Implement Multi-Factor Authentication: There are statistics that show how often user accounts are attacked, it is important to incorporate multi-factor authentication to further secure the accounts.

• Deploy Advanced Malware Protection: Provide robust guard that will help the user recognize and prevent the execution of the DISGOMOJI malware and similar threats.

• Enhance Network Segmentation: Utilize stringent network isolation mechanisms that seek to compartmentalize the key systems and data from the rest of the network in order to minimize the attack exposure.

• Monitor Network Activity: Scanning Network hour to hour for identifying and handling the security breach and the tools such as Nmap, Chisel, Ligolo etc can be used.

• Utilize Threat Intelligence: To leverage advanced threats intelligence which will help you acquire knowledge on previous threats and vulnerabilities and take informed actions.

• Secure Communication Channels: Mitigate the problem of the leakage of developers’ credentials and ways of engaging with the discord through loss of contact to prevent abusing attacks or gaining control over Discord as an attack vector.

• Enforce Access Control: Regularly review and update the user authentication processes by adopting stricter access control measures that will allow only the right personnel to access the right systems and information.

• Conduct Regular Security Audits: It is important to engage in security audits periodically in an effort to check some of the weaknesses present within the network or systems.

• Implement Incident Response Plan: Conduct a risk assessment, based on that design and establish an efficient incident response kit that helps in the early identification, isolation, and management of security breaches.

• Educate Users: Educate users on cybersecurity hygiene, opportunities to strengthen affinity with the University, and conduct retraining on threats like phishing and social engineering.

Conclusion:

The new threat actor named UTA0137 from Pakistan who was utilizing DISGOMOJI malware to attack Indian government institutions using embedded emojis with a command line through the Discord app was discovered by Volexity. It has the capability to exfiltrate and aims to steal the data of government entities. The UTA0137 was continuously improved over time to permanently communicate with victims. It underlines the necessity of having strong protection from viruses and hacker attacks, using secure passwords and unique codes every time, updating the software more often and having high-level anti-malware tools. Organizations can minimize advanced threats, the likes of DISGOMOJI and protect sensitive data by improving network segmentation, continuous monitoring of activities, and users’ awareness.

Introduction

February marks the beginning of Valentine’s Week, the time when we transcend from the season of smog to the season of love. This is a time when young people are more active on social media and dating apps with the hope of finding a partner to celebrate the occasion. Dating Apps, in order to capitalise on this occasion, launch special offers and campaigns to attract new users and string on the current users with the aspiration of finding their ideal partner. However, with the growing popularity of online dating, the tactics of cybercriminals have also penetrated this sphere. Scammers are now becoming increasingly sophisticated in manipulating individuals on digital platforms, often engaging in scams, identity theft, and financial fraud under the guise of romance. As love fills the air, netizens must stay vigilant and cautious while searching for a connection online and not fall into a scammer’s trap. 

Here Are Some CyberPeace Tips To Avoid Romance Scams

• Recognize Red Flags of Romance Scams:- Online dating has made it easier to connect with people, but it has also become a tool for scammers to exploit the emotions of netizens for financial gain. They create fake profiles, build trust quickly, and then manipulate victims into sending money. Understanding their tactics can help you stay safe.
• Warning Signs of a Romance Scam:- If someone expresses strong feelings too soon, it’s a red flag. Scammers often claim to have fallen in love within days or weeks, despite never meeting in person. They use emotional pressure to create a false sense of connection.  Their messages might seem off. Scammers often copy-paste scripted responses, making conversations feel unnatural. Poor grammar, inconsistencies in their stories, or vague answers are warning signs. Asking for money is the biggest red flag. They might have an emergency, a visa issue, or an investment opportunity they want you to help with. No legitimate relationship starts with financial requests.
• Manipulative Tactics Used by Scammers:- Scammers use love bombing to gain trust. They flood you with compliments, calling you their soulmate or destiny. This is meant to make you emotionally attached. They often share fake sob stories. It could be anything ranging from losing a loved one, facing a medical emergency, or even being stuck in a foreign country. These are designed to make you feel sorry for them and more willing to help. Some of these scammers might even pretend to be wealthy, being investors or successful business owners, showing off their fabricated luxury lifestyle in order to appear credible. Eventually, they’ll try to lure you into a fake investment. They create a sense of urgency. Whether it’s sending money, investing, or sharing personal details, scammers will push you to act fast. This prevents you from thinking critically or verifying your claims.
• Financial Frauds Linked to Romance Scams:- Romance scams have often led to financial fraud. Victims may be tricked into sending money directly or get roped into elaborate schemes. One common scam is the disappearing date, where someone insists on dining at an expensive restaurant, only to vanish before the bill arrives. Crypto scams are another major concern. Scammers convince victims to invest in fake cryptocurrency platforms, promising huge returns. Once the money is sent, the scammer disappears, leaving the victim with nothing. 
• AI & Deepfake Risks in Online Dating:- Advancements in AI have made scams even more convincing. Scammers use AI-generated photos to create flawless, yet fake, profile pictures. These images often lack natural imperfections, making them hard to spot. Deepfake technology is also being used for video calls. Some scammers use pre-recorded AI-generated videos to fake live interactions. If a person’s expressions don’t match their words or their screen glitches oddly, it could be a deepfake.
• How to Stay Safe:-
  • Always verify the identities of those who contact you on these sites. A simple reverse image search can reveal if someone’s profile picture is stolen.
  • Avoid clicking suspicious links or downloading unknown apps sent by strangers. These can be used to steal your personal information.
  • Trust your instincts. If something feels off, it probably is. Stay alert and protect yourself from online romance scams.

Best Online Safety Practices

• Prioritize Social Media Privacy:- Review and update your privacy settings regularly. Think before you share and be mindful of who can see your posts/stories. Avoid oversharing personal details.
• Report Suspicious Activities:- Even if a scam attempt doesn’t succeed, report it. Indian Cyber Crime Coordination Centre (I4C) 'Report Suspect' feature allow users to flag potential threats, helping prevent cybercrimes.
• Think Before You Click or Download:- Avoid clicking on unknown links or downloading attachments from unverified sources. These can be traps leading to phishing scams or malware attacks.
• Protect Your Personal Information:- Be cautious with whom and how you share your sensitive details online. Cybercriminals exploit even the smallest data points to orchestrate fraud.

Introduction

AI has penetrated most industries and telecom is no exception. According to a survey by Nvidia, enhancing customer experiences is the biggest AI opportunity for the telecom industry, with 35% of respondents identifying customer experiences as their key AI success story. Further, the study found nearly 90% of telecom companies use AI, with 48% in the piloting phase and 41% actively deploying AI. Most telecom service providers (53%) agree or strongly agree that adopting AI would provide a competitive advantage. AI in telecom is primed to be the next big thing and Google has not ignored this opportunity. It is reported that Google will soon add “AI Replies” to the phone app’s call screening feature. 

How Does The ‘AI Call Screener’ Work?

With the busy lives people lead nowadays, Google has created a helpful tool to answer the challenge of responding to calls amidst busy schedules. Google Pixel smartphones are now fitted with a new feature that deploys AI-powered calling tools that can help with call screening, note-making during an important call, filtering and declining spam, and most importantly ending the frustration of being on hold.  

In the official Google Phone app, users can respond to a caller through “new AI-powered smart replies”. While “contextual call screen replies” are already part of the app,  this new feature allows users to not have to pick up the call themselves. 

• With this new feature,  Google Assistant will be able to respond to the call with a customised audio response.
• The Google Assistant, responding to the call, will ask the caller’s name and the purpose of the call. If they are calling about an appointment, for instance, Google will show the user suggested responses specific to that call, such as ‘Confirm’ or ‘Cancel appointment’.

Google will build on the call-screening feature by using a “multi-step, multi-turn conversational AI” to suggest replies more appropriate to the nature of the call. Google’s Gemini Nano AI model is set to power this new feature and enable it to handle phone calls and messages even if the phone is locked and respond even when the caller is silent.

Benefits of AI-Powered Call Screening

This AI-powered call screening feature offers multiple benefits:

1. The AI feature will enhance user convenience by reducing the disruptions caused by spam calls. This will, in turn, increase productivity.
2. It will increase call privacy and security by filtering high-risk calls, thereby protecting users from attempts of fraud and cyber crimes such as phishing.  
3. The new feature can potentially increase efficiency in business communications by screening for important calls, delegating routine inquiries and optimising customer service. 

Key Policy Considerations

Adhering to transparent, ethical, and inclusive policies while anticipating regulatory changes can establish Google as a responsible innovator in AI call management. Some key considerations for AI Call Screener from a policy perspective are:

1. The AI screen caller will process and transcribe sensitive voice data, therefore, the data handling policies for such need to be transparent to reassure users of regulatory compliance with various laws. 
2. AI has been at a crossroads in its ethical use and mitigation of bias. It will require the algorithms to be designed to avoid bias and reflect inclusivity in its understanding of language. 
3. The data that the screener will be using is further complicated by global and regional regulations such as data privacy regulations like the GDPR, DPDP Act, CCPA etc., for consent to record or transcribe calls while focussing on user rights and regulations. 

Conclusion: A Balanced Approach to AI in Telecommunications

Google’s AI Call Screener offers a glimpse into the future of automated call management, reshaping customer service and telemarketing by streamlining interactions and reducing spam. As this technology evolves, businesses may adopt similar tools, balancing customer engagement with fewer unwanted calls. The AI-driven screening will also impact call centres, shifting roles toward complex, human-centred interactions while automation handles routine calls. They could have a potential effect on support and managerial roles. Ultimately, as AI call management grows, responsible design and transparency will be in demand to ensure a seamless, beneficial experience for all users.
