India’s Leap into the Future, the First AI Laboratory in Space

Introduction

In the labyrinthine world of cybersecurity, a new spectre has emerged from the digital ether, casting a long shadow over the seemingly impregnable orchards of Apple's macOS. This phantom, known as SpectralBlur, is a backdoor so cunningly crafted that it remained shrouded in the obscurity of cyberspace, undetected by the vigilant eyes of antivirus software until its recent unmasking. The discovery of SpectralBlur is not just a tale of technological intrigue but a narrative that weaves together the threads of geopolitical manoeuvring, the relentless pursuit of digital supremacy, and the ever-evolving landscape of cyber warfare.

SpectralBlur, a term that conjures images of ghostly interference and elusive threats, is indeed a fitting moniker for this new macOS backdoor threat. Cybersecurity researchers have peeled back the layers of the digital onion to reveal a moderately capable backdoor that can upload and download files, execute shell commands, update its configuration, delete files, and enter states of hibernation or sleep, all at the behest of a remote command-and-control server. Greg Lesnewich, a security researcher whose name has become synonymous with the relentless pursuit of digital malefactors, has shed light on this new threat that overlaps with a known malware family attributed to the enigmatic North Korean threat actors.

SpectralBlur similar to Lazarus Group’s KANDYKORN

The malware shares its DNA with KANDYKORN, also known as SockRacket, an advanced implant that functions as a remote access trojan capable of taking control of a compromised host. It is a digital puppeteer, pulling the strings of infected systems with a malevolent grace. The KANDYKORN activity also intersects with another campaign orchestrated by the Lazarus sub-group known as BlueNoroff, or TA444, which culminates in the deployment of a backdoor referred to as RustBucket and a late-stage payload dubbed ObjCShellz.

Recently, the threat actor has been observed combining disparate pieces of these two infection chains, leveraging RustBucket droppers to deliver KANDYKORN. This latest finding is another sign that North Korean threat actors are increasingly setting their sights on macOS to infiltrate high-value targets, particularly those within the cryptocurrency and blockchain industries. 'TA444 keeps running fast and furious with these new macOS malware families,' Lesnewich remarked, painting a picture of a relentless adversary in the digital realm.

Patrick Wardle, a security researcher whose insights into the inner workings of SpectralBlur have further illuminated the threat landscape, noted that the Mach-O binary was uploaded to the VirusTotal malware scanning service in August 2023 from Colombia. The functional similarities between KANDYKORN and SpectralBlur have raised the possibility that they may have been built by different developers with the same requirements. What makes the malware stand out are its attempts to hinder analysis and evade detection while using grant to set up a pseudo-terminal and execute shell commands received from the C2 server.

The disclosure comes as 21 new malware families designed to target macOS systems, including ransomware, information stealers, remote access trojans, and nation-state-backed malware, were discovered in 2023, up from 13 identified in 2022. 'With the continued growth and popularity of macOS (especially in the enterprise!), 2024 will surely bring a bevvy of new macOS malware,' Wardle noted, his words a harbinger of the digital storms on the horizon.

Hackers are beefing up their efforts to go after the best MacBooks as security researchers have discovered a brand new macOS backdoor which appears to have ties to another recently identified Mac malware strain. As reported by Security Week, this new Mac malware has been dubbed SpectralBlur and although it was uploaded to VirusTotal back in August of last year, it remained undetected by the best antivirus software until it recently caught the attention of Proofpoint’s Greg Lesnewich.

Lesnewich explained that SpectralBlur has similar capabilities to other backdoors as it can upload and download files, delete files and hibernate or sleep when given commands from a hacker-controlled command-and-control (C2) server. What is surprising about this new Mac malware strain though is that it shares similarities to the KandyKorn macOS backdoor which was created by the infamous North Korean hacking group Lazarus.

Just like SpectralBlur, KandyKorn is designed to evade detection while providing the hackers behind it with the ability to monitor and control infected Macs. Although different, these two Mac malware strains appear to be built based on the same requirements. Once installed on a vulnerable Mac, SpectralBlur executes a function that allows it to decrypt and encrypt network traffic to help it avoid being detected. However, it can also erase files after opening them and then overwrite the data they contain with zeros..

How to keep your Apple computers safe from hackers

As with the best iPhones, keeping your Mac up to date is the easiest and most important way to keep it safe from hackers. Hackers often prey on users who haven’t updated their devices to the latest software as they can exploit unpatched vulnerabilities and security flaws.

Checking to see if you're running the latest macOS version is quite easy. Just click on the Apple Logo in the top right corner of your computer, head to System Preferences and then click on Software Update. If you need a bit more help, check out our guide on how to update a Mac for more detailed instructions with pictures.

Even though your Mac has its own built-in malware scanner from Apple called xProtect, you should consider using one of the best Mac antivirus software solutions for additional protection. Paid antivirus software is often updated more frequently and you often also get access to other extras to help keep you safe online like a password manager or a VPN.

Besides updating your Mac frequently and using antivirus software, you must be careful online. This means sticking to trusted online retailers, carefully checking the URLs of the websites you visit and avoiding opening links and attachments sent to you via email or social media from people you don’t know. Likewise, you should also learn how to spot a phishing scam to know which emails you want to delete right away.

Conclusion 

The thing about hackers and other cybercriminals is that they are constantly evolving their tactics and attack methods. This helps them avoid detection and allows them to devise brand-new ways to trick ordinary people. With the surge we saw in Mac malware last year, though, Apple will likely be working on beefing up xProtect and macOS to better defend against these new threats.

About Customs Scam:

The Customs Scam is a type of fraud where the scammers pretend to be from the renowned courier office company (DTDC, etc.), or customs department or other government entities. They try to deceive the targets to transfer the money to resolve the fake customs related concerns.  The Research Wing at CyberPeace along with the Research Wing of Autobot Infosec Private Ltd. delved into this case through Open Source Intelligence methods and undercover interactions with the scammers and concluded with some credible information.

Case Study:

The victim receives a phone call posing as a renowned courier office (DTDC, etc.) employee (in some case custom’s officer) that a parcel in the name of the victim has been taken into custody because of inappropriate content. The scammer provides the victim an employee ID, FIR number to prove the authenticity of the case and also they show empathy towards the victim. The scammer pretends to help the victim to connect with a police officer for further action. This so-called police officer shows transparency in his work. He asks him to join a skype video call and he even provides time to install the skype app. He instructs the victim to connect with the skype id provided by the fake police officer where the scammer created a fake police station environment. He also claims that he contacted the headquarters and the victim’s phone number is associated with many illegal activities to create panic to the victim.  Then the scammers also ask the victim to give their personal details such as home address, office address, aadhar card number, PAN card number and screenshot of their bank accounts along with their available account balance for the sake of so-called investigation. Sometimes scammers also demand a high amount of money to resolve the issue and create fake urgency to trap the victim in making the payment. He sternly warns the victim not to contact any other police officials or professionals, making it clear that doing so would only lead to more trouble.

Analysis & Findings: 

After receiving these kinds of complaints from multiple sources, the analysis was done on the collection of phone numbers from where the calls originated. These phone numbers were analysed for alias name, location, Telecom operator,  etc.  Further, we have verified the number to check whether the number is linked with any social media account on reputed platforms like Google, Facebook, Whatsapp, Twitter, Instagram, Linkedin, and other classified platforms such as Locanto.

• Phone Number Analysis: Each phone number looks authentic, cleverly concealing the fraud. Sometimes scammers use virtual/temporary phone numbers for these kinds of scams. In this case the victim was from Delhi, so the scammer posed themselves from Delhi Police station, while the phone numbers belong to a different place.

• Undercover Interactions:  The interactions with the suspects reveals their chilling way of modus operandi. These scammers are masters of psychological manipulation. They threaten the victims and act as if they are genuine LEA officers. 
• Exploitation Tactics: They target unsuspecting individuals and create fear and fake urgency among the targets to extract sensitive information such as Aadhaar, PAN card and bank account details.

• Fraud Execution: The scammers demand for the payment to resolve this issue and they make use of the stolen personally identifiable information. Once the victims transfer the money, the fraudsters cut off all the communication.
• Outcome for Victims:  The scammers act so genuine and they frame the incidents so realistic, victims don't realise that they are trapped in this scam. They suffer severe financial loss and psychological trauma.

Recommendations:

• Verify Identities: It is important to verify the identity of any individual, especially if they demand personal information or payment. Contact the official agency directly using verified contact details to confirm the authenticity of the communication.
• Education on Personal Information: Provide education to people to protect their personal identity numbers like Aadhaar and PAN card number. Always emphasise the possible dangers connected to sharing such data in the course of phone conversations.
• Report Suspicious Activity: Prompt reporting of suspicious phone calls or messages to relevant authorities and consumer protection agencies helps in tracking down scammers and prevents people from falling. Report to https://cybercrime.gov.in or reach out to helpline@cyberpeace.net for further assistance. 
• Enhanced Cybersecurity Measures: Implement robust cybersecurity measures to detect and mitigate phishing attempts and fraudulent activities. This includes monitoring and blocking suspicious phone numbers and IP addresses associated with scams.

Conclusion:

In the Customs Scam fraud, the scammers pretend to be a custom or any government official and sometimes threaten the targets to get the details such as Aadhaar, PAN card details, screenshot of their bank accounts along with their available balance in their account. The phone numbers used for these kinds of scams were analysed for any suspicious activity. It is found that all the phone numbers look authentic concealing the fraudentent activities. The interactions made with them reveals that they create fearness and urgency between the individuals. They act as if they are genuine officer’s and ask for money to resolve this issue. It is important to stay vigilant and not to share any personal or financial information. When facing these kinds of scams, report and spread awareness among individuals.

Along with the loss of important files and information, data loss can result in downtime and lost revenue. Unexpected occurrences, including natural catastrophes, cyber-attacks, hardware malfunctions, and human mistakes, can result in the loss of crucial data. Recovery from these without a backup plan may be difficult, if not impossible.

The fact is that the largest threat to the continuation of your organization today is cyberattacks. Because of this, disaster recovery planning should be approached from a data security standpoint. If not, you run the risk of leaving your vital systems exposed to a cyberattack. Cybercrime has been more frequent and violent over the past few years. In the past, major organizations and global businesses were the main targets of these attacks by criminals. But nowadays, businesses of all sizes need to be cautious of digital risks.

Many firms might suffer a financial hit even from a brief interruption to regular business operations. But imagine if a situation forced a company to close for a few days or perhaps weeks! The consequences would be disastrous.

One must have a comprehensive disaster recovery plan in place that is connected with the cybersecurity strategy, given the growing danger of cybercrime.

Let’s look at why having a solid data security plan and a dependable backup solution are essential for safeguarding a company from external digital threats.

1. Apply layered approaches

One must specifically use precautionary measures like antivirus software and firewalls. One must also implement strict access control procedures to restrict who may access the network.

One must also implement strict access control procedures to restrict who may access the network.

2. Understand the threat situation

If someone is unaware of the difficulties one should be prepared for, how can they possibly expect to develop a successful cybersecurity strategy? They can’t, is the simple response.

Without a solid understanding of the threat landscape, developing the plan will require a lot too much speculation. With this strategy, one can allocate resources poorly or perhaps completely miss a threat.

Because of this, one should educate themselves on the many cyber risks that businesses now must contend with.

3. Adopt a proactive security stance

Every effective cybersecurity plan includes a number of reactive processes that aren’t activated until an attack occurs. Although these reactive strategies will always be useful in cybersecurity, the main focus of your plan should be proactiveness.

There are several methods to be proactive, but the most crucial one is to analyze your network for possible threats regularly. your network securely. Having a SaaS Security Posture Management (SSPM) solution in place is beneficial for SaaS applications, in particular.

A preventive approach can lessen the effects of a data breach and aid in keeping data away from attackers.

4. Evaluate your ability to respond to incidents

Test your cybersecurity disaster recovery plan’s effectiveness by conducting exercises and evaluating the outcomes. Track pertinent data during the exercise to see if your plan is working as expected.

Meet with your team after each drill to evaluate what went well and what didn’t. This strategy enables you to continuously strengthen your plan and solve weaknesses. This procedure may be repeated endlessly and should be.

You must include cybersecurity protections in your entire disaster recovery plan if you want to make sure that your business is resilient in the face of cyber threats. You may strengthen data security and recover from data loss and corruption by putting in place a plan that focuses on both the essential components of proactive data protection and automated data backup and recovery.

For instance, Google distributes all data among several computers in various places while storing each user’s data on a single machine or collection of machines. To prevent a single point of failure, chunk the data and duplicate it across several platforms. As an additional security safeguard, they give these data chunks random names that are unreadable to the human eye.^[1]

The process of creating and storing copies of data that may be used to safeguard organizations against data loss is referred to as backup and recovery. In the case of a main data failure, the backup’s goal is to make a duplicate of the data that can be restored.

5. Take zero-trust principles

Don’t presume that anything or anybody can be trusted; zero trust is a new label for an old idea. Check each device, user, service, or other entity’s trustworthiness before providing it access, then periodically recheck trustworthiness while access is allowed to make sure the entity hasn’t been hacked. Reduce the consequences of any breach of confidence by granting each entity access to only the resources it requires. The number of events and the severity of those that do happen can both be decreased by using zero-trust principles.

6. Understand the dangers posed by supply networks

A nation-state can effectively penetrate a single business, and that business may provide thousands of other businesses with tainted technological goods or services. These businesses will then become compromised, which might disclose their own customers’ data to the original attackers or result in compromised services being offered to customers. Millions of businesses and people might be harmed as a result of what began with one infiltrating corporation.

In conclusion, a defense-in-depth approach to cybersecurity won’t vanish. Organizations may never be able to totally eliminate the danger of a cyberattack, but having a variety of technologies and procedures in place can assist in guaranteeing that the risks are kept to a minimum.
