TRAI issues guidelines to Access Service Providers to prevent misuse of messaging services

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.

March 3rd 2023, New Delhi: If you have received any message that contains a link asking users to download an application to avail Income Tax Refund or KYC benefits with the name of Income Tax Department or reputed Banks, Beware!

CyberPeace Foundation and Autobot Infosec Private Limited along with the academic partners under CyberPeace Center of Excellence (CCoE) recently conducted five different studies on phishing campaigns that have been circulating on the internet by using misleading tactics to convince users to install malicious applications on their devices. The first campaign impersonates the Income Tax Department, while the rest of the campaigns impersonate ICICI Bank, State Bank of India, IDFC Bank and Axis bank respectively. The phishing campaigns aim to trick users into divulging their personal and financial information.

After a detailed study, the research team found that:

• All campaigns appear to be an offer from reputed entities, however hosted on third-party domains instead of the official website of the Income Tax Department or the respective Banks, raising suspicion.
• The applications ask several access permissions of the device. Moreover some of them seek users to provide full control of the device. Allowing such access permission could result in a complete compromise of the system, including access to sensitive information such as microphone recordings, camera footage, text messages, contacts, pictures, videos, and even banking applications.
• Cybercriminals created malicious applications using icons that closely resemble those of legitimate entities with the intention of enticing users into downloading the malicious applications.
• The applications collect user’s personal and banking information. Getting into this type of trap could lead users to face significant financial losses.
• While investigating the impersonated Income Tax Department’s application, the Research team identified the application sends http traffic to a remote server which acts as a Command and Control (CnC/C2) for the application.
• Customers who desire to avail benefits or refunds from respective banks, download relevant apps, believing that the chosen app will assist them. However, they are not always aware that the app may be fraudulent.

“The Research highlights the importance of being vigilant while browsing the internet and not falling prey to such phishing attacks. It is crucial to be cautious when clicking on links or downloading attachments from unknown sources, as they may contain malware that can harm the device or compromise the data.” spokesperson, CyberPeace added.

In addition to this in an earlier report released in last month, the same research team had drawn attention to the WhatsApp messages masquerading as an offer from Tanishq Jewellers with links luring unsuspecting users with the promise of free valentine’s day  presents making the rounds on the app.

CyberPeace Advisory:

• The Research team recommends that people should avoid opening such messages sent via social platforms. One must always think before clicking on such links, or downloading any attachments from unauthorised sources.
• Downloading any application from any third party sources instead of the official app store should be avoided. This will greatly reduce the risk of downloading a malicious app, as official app stores have strict guidelines for app developers and review each app before it gets published on the store.
• Even if you download the application from an authorised source, check the app’s permissions before you install it. Some malicious apps may request access to sensitive information or resources on your device. If an app is asking for too many permissions, it’s best to avoid it.
• Keep your device and the app-store app up to date. This will ensure that you have the latest security updates and bug fixes.
• Falling into such a trap could result in a complete compromise of the system, including access to sensitive information such as microphone recordings, camera footage, text messages, contacts, pictures, videos, and even banking applications and could lead users to financial loss.
• Do not share confidential details like credentials, banking information with such types of Phishing scams.
• Never share or forward fake messages containing links on any social platform without proper verification.

Executive Summary:

A misleading video of a child covered in ash allegedly circulating as the evidence for attacks against Hindu minorities in Bangladesh. However, the  investigation revealed that the video is actually from Gaza, Palestine, and was filmed following an Israeli airstrike in July 2024. The claim linking the video to Bangladesh is false and misleading.

Claims:

A viral video claims to show a child in Bangladesh covered in ash as evidence of attacks on Hindu minorities.

Fact Check:

Upon receiving the viral posts, we conducted a Google Lens search on keyframes of the video, which led us to a X post posted by Quds News Network. The report identified the video as footage from Gaza, Palestine, specifically capturing the aftermath of an Israeli airstrike on the Nuseirat refugee camp in July 2024.

The caption of the post reads, “Journalist Hani Mahmoud reports on the deadly Israeli attack yesterday which targeted a UN school in Nuseirat, killing at least 17 people who were sheltering inside and injuring many more.”

‍

To further verify, we examined the video footage where the watermark of Al Jazeera News media could be seen, We found the same post posted on the Instagram account on 14 July, 2024 where we confirmed that the child in the video had survived a massacre caused by the Israeli airstrike on a school shelter in Gaza. 

‍

Additionally, we found the same video uploaded to CBS News' YouTube channel, where it was clearly captioned as "Video captures aftermath of Israeli airstrike in Gaza",  further confirming its true origin.

‍

We found no credible reports or evidence were found linking this video to any incidents in Bangladesh. This clearly implies that the viral video was falsely attributed to Bangladesh. 

Conclusion:

The video circulating on social media which shows a child covered in ash as the evidence of attack against Hindu minorities is false and misleading. The investigation leads that the video originally originated from Gaza, Palestine and documents the aftermath of an Israeli air strike in July 2024.  

• Claims: A video shows a child in Bangladesh covered in ash as evidence of attacks on Hindu minorities.
• Claimed by: Facebook
• Fact Check: False & Misleading
