Introduction
The mysteries of the universe have been a subject of curiosity for humans over thousands of years. To solve these unfolding mysteries of the universe, astrophysicists are always busy, and with the growing technology this seems to be achievable. Recently, with the help of Artificial Intelligence (AI), scientists have discovered the depths of the cosmos. AI has revealed the secret equation that properly “weighs” galaxy clusters. This groundbreaking discovery not only sheds light on the formation and behavior of these clusters but also marks a turning point in the investigation and discoveries of new cosmos. Scientists and AI have collaborated to uncover an astounding 430,000 galaxies strewn throughout the cosmos. The large haul includes 30,000 ring galaxies, which are considered the most unusual of all galaxy forms. The discoveries are the first outcomes of the "GALAXY CRUISE" citizen science initiative. They were given by 10,000 volunteers who sifted through data from the Subaru Telescope. After training the AI on 20,000 human-classified galaxies, scientists released it loose on 700,000 galaxies from the Subaru data.
Brief Analysis
A group of astronomers from the National Astronomical Observatory of Japan (NAOJ) have successfully applied AI to ultra-wide field-of-view images captured by the Subaru Telescope. The researchers achieved a high accuracy rate in finding and classifying spiral galaxies, with the technique being used alongside citizen science for future discoveries.
Astronomers are increasingly using AI to analyse and clean raw astronomical images for scientific research. This involves feeding photos of galaxies into neural network algorithms, which can identify patterns in real data more quickly and less prone to error than manual classification. These networks have numerous interconnected nodes and can recognise patterns, with algorithms now 98% accurate in categorising galaxies.
Another application of AI is to explore the nature of the universe, particularly dark matter and dark energy, which make up over 95% energy of the universe. The quantity and changes in these elements have significant implications for everything from galaxy arrangement.
AI is capable of analysing massive amounts of data, as training data for dark matter and energy comes from complex computer simulations. The neural network is fed these findings to learn about the changing parameters of the universe, allowing cosmologists to target the network towards actual data.
These methods are becoming increasingly important as astronomical observatories generate enormous amounts of data. High-resolution photographs of the sky will be produced from over 60 petabytes of raw data by the Vera C. AI-assisted computers are being utilized for this.
Data annotation techniques for training neural networks include simple tagging and more advanced types like image classification, which classify an image to understand it as a whole. More advanced data annotation methods, such as semantic segmentation, involve grouping an image into clusters and giving each cluster a label.
This way, AI is being used for space exploration and is becoming a crucial tool. It also enables the processing and analysis of vast amounts of data. This advanced technology is fostering the understanding of the universe. However, clear policy guidelines and ethical use of technology should be prioritized while harnessing the true potential of contemporary technology.
Policy Recommendation
- Real-Time Data Sharing and Collaboration - Effective policies and frameworks should be established to promote real-time data sharing among astronomers, AI developers and research institutes. Open access to astronomical data should be encouraged to facilitate better innovation and bolster the application of AI in space exploration.
- Ethical AI Use - Proper guidelines and a well-structured ethical framework can facilitate judicious AI use in space exploration. The framework can play a critical role in addressing AI issues pertaining to data privacy, AI Algorithm bias and transparent decision-making processes involving AI-based tech.
- Investing in Research and Development (R&D) in the AI sector - Government and corporate giants should prioritise this opportunity to capitalise on the avenue of AI R&D in the field of space tech and exploration. Such as funding initiatives focusing on developing AI algorithms coded for processing astronomical data, optimising telescope operations and detecting celestial bodies.
- Citizen Science and Public Engagement - Promotion of citizen science initiatives can allow better leverage of AI tools to involve the public in astronomical research. Prominent examples include the SETI @ Home program (Search for Extraterrestrial Intelligence), encouraging better outreach to educate and engage citizens in AI-enabled discovery programs such as the identification of exoplanets, classification of galaxies and discovery of life beyond earth through detecting anomalies in radio waves.
- Education and Training - Training programs should be implemented to educate astronomers in AI techniques and the intricacies of data science. There is a need to foster collaboration between AI experts, data scientists and astronomers to harness the full potential of AI in space exploration.
- Bolster Computing Infrastructure - Authorities should ensure proper computing infrastructure should be implemented to facilitate better application of AI in astronomy. This further calls for greater investment in high-performance computing devices and structures to process large amounts of data and AI modelling to analyze astronomical data.
Conclusion
AI has seen an expansive growth in the field of space exploration. As seen, its multifaceted use cases include discovering new galaxies and classifying celestial objects by analyzing the changing parameters of outer space. Nevertheless, to fully harness its potential, robust policy and regulatory initiatives are required to bolster real-time data sharing not just within the scientific community but also between nations. Policy considerations such as investment in research, promoting citizen scientific initiatives and ensuring education and funding for astronomers. A critical aspect is improving key computing infrastructure, which is crucial for processing the vast amount of data generated by astronomical observatories.

Introduction
A zero-click cyber attack solely relies on software and hardware flaws, bypassing any human factor to infect a device and take control over its data. It is almost impossible to discover the attack and know that the device is hacked unless someone on your side is closely monitoring your network traffic data.
At Kaspersky, security analysts used their SIEM solution KUMA to monitor their corporate WiFi network traffic and discovered this mysterious attack. They took necessary actions to investigate it and even went a step further to dive right into the action and uncover the entire attack chain.
A few months ago, Kaspersky shared their findings about this attack on iOS devices. They shared how these zero-click vulnerabilities were being exploited by the attackers and called this attack ‘Operation Triangulation’.
A zero-click exploit in the network
Kaspersky detected a zero-click attack on the iPhones of their colleagues while monitoring their corporate WiFi network traffic. They managed to get detailed information on all the stages of the attack by simply identifying a pattern in the domain names flowing through their network. Although the attackers were quite experienced, their mistakes helped Kaspersky detect critical vulnerabilities in all iOS devices.
The name-pattern
These previously unsuspected domains had a similar name-style which consisted of two names and ended with ‘.com’, such as ‘backuprabbit.com’ and ‘cloudsponcer.com’. They were used in pairs, one for an exportation process and the other served as a command and control server. These domains showed high outbound traffic, they were registered with NameCheap and protected with Cloudflare.
The network pattern
Each time a connection to these suspicious domains was made, it was preceded by an iMessage connection which indicated these domains are being accessed by iOS devices. It was observed that the devices connected to these domains, downloaded attachments, performed a few requests to a first level domain which was an exploitation framework server, then made regular connections with the second level domain which was a command and control server controlled by the attackers.
Getting more information
To get more information about the attack all the infected devices were collected and backed up after carefully informing the device owners. Although the attackers had managed to clean their artefacts, the backed up data was used to perform digital forensic procedures and find traces of the attacks. This helped Kaspersky to figure out how the infection might be taking place.
The attacker’s mistakes
The attackers deleted all the attachment files and exploits but did not delete the modified SMS attachment folder. That folder had no files left inside it. The attackers removed evidence from other databases as well, like the ‘SMS.db’ database, however another database called ‘datausage.sqlite’ was not sanitised.
The ‘datausage.sqlite’ database is the most important database when it comes to iOS forensics as its contents can be used to track applications and network usage. Upon examination of this database, a process logged as ‘BackupAgent’ was found to be making network connections at the same time the device was making connections to the suspicious domains.
The indicator of compromise
‘BackupAgent’ stood out in this scenario because although it is a legitimate binary, it has been deprecated since iOS4 and it should not have been making any network connections. This identified the ‘BackupAgent’ process as the first solid indicator of compromise in Operation Triangulation. The indicator is termed as- ‘Data usage by process BackupAgent’, and was used to determine if any specific device was infected.
Taking it a step ahead
The team at Kaspersky successfully identified the indicator of compromise and determined which devices were infected, but as the attackers were experienced enough to delete their payloads, they decided to set a trap and perform a man-in-the-middle attack. When they did, the attackers were unable to detect it.
The man-in the-middle attack
Kaspersky prepared a server with ‘WireGuard’ and ‘mitmproxy’. They installed root certificates on devices that could be used as targets for the attackers and routed all the network traffic to that server. They also developed a ‘Telegram’ bot to notify them about new infections as they decrypted the network traffic.
Setting up a bot proved to be an effective way of real time monitoring while modifying all the network packets on-the-fly with ‘mitmproxy’, this gave them unlimited power! Their trap was successful in capturing a payload sent by the attackers and it was analysed in detail.
The name was in the payload
The payload was an HTML page with obfuscator javascript which performed various code checks and canvas footprinting. It rendered a yellow triangle and calculated its hash value. This is why the operation was named Operation Triangulation.
The team at Kaspersky started cracking various layers of asymmetric cryptography with regular expressions. They patched the stages one-by-one on the fly to move the logic from each stage to ‘mitmproxy’ and finally implemented a 400 line ‘mitmproxy’ add-on. This add-on decrypted all the validators, exploits, spyware and additional modules.
The mystery
It is remarkable how Kaspersky detected the attack and identified multiple vulnerabilities, set up a trap to capture a payload and decrypted it completely. They shared all their findings with the device manufacturer and Apple responded by sending out a security patch update addressing four zero-day vulnerabilities.
A zero-click vulnerability
Traditionally any spyware relies on the user to to click on a compromised link or file to initiate the infection. However a zero-click vulnerability is a specific flaw in the device software or hardware that the attacker can use to infect the device without the need for a click or tap from the user.
The vulnerabilities identified
- Tricky Font Flaw (CVE-2023-41990): A clandestine method involving the manipulation of font rendering on iPhones, akin to a secret code deciphered by the attackers.Apple swiftly addressed this vulnerability in versions iOS 15.7.8 and iOS 16.3.
- Kernel Trick (CVE-2023-32434): Exploiting a hidden language understood only by the iPhone's core, the attackers successfully compromised the kernel's integrity.Apple responded with fixes implemented in iOS 15.7.7, iOS 15.8, and iOS 16.5.1.
- Web Sneakiness (CVE-2023-32435): Leveraging a clever ploy in the interpretation of web content by iPhones, the attackers manipulated the device's behaviour.Apple addressed this vulnerability in iOS 15.7.7 and iOS 16.5.1.
- Kernel Key (CVE-2023-38606): The pinnacle of the operation, the attackers discovered a covert method to tamper with the iPhone's core, the kernel.Apple responded with a fix introduced in iOS 16.6, thwarting the intrusion into the most secure facets of the iPhone
Still, how these attackers were able to find this critical vulnerability in a device which stands out for it’s security features is still unknown.
CyberPeace Advisory
Zero-click attacks are a real threat, but you can defend yourself. Being aware of the risks and taking proactive steps can significantly reduce vulnerability. Regularly installing the latest updates for your operating system, apps, and firmware helps patch vulnerabilities before attackers can exploit them.
- Keep your software updated as they contain crucial security patches that plug vulnerabilities before attackers can exploit them.
- Use security software to actively scan for suspicious activity and malicious code, acting as a first line of defence against zero-click intrusions.
- Be cautious with unsolicited messages if the offer seems too good to be true or the link appears suspicious as it can contain malware that can infect your device.
- Disable automatic previews as it can potentially trigger malicious code hidden within the content.
- Be mindful of what you install and avoid unverified apps and pirated software, as they can be Trojan horses laden with malware.
- Stay informed about the latest threats and updates by following reliable news sources and security blogs to stay ahead of the curve, recognize potential zero-click scams and adjust your behaviour accordingly.

Introduction
In the vast expanse of the digital cosmos, where the tendrils of the internet weave an intricate tapestry of connectivity, the channels through which information cascades have become a labyrinth of enigma and complexity. As we traverse this boundless virtual landscape, the line demarcating fact from fiction blurs, leaving the essence of truth adrift in a deluge of data. Amidst this ceaseless flow, platforms such as YouTube, Meta, and Twitter emerge as bulwarks in a pivotal struggle against the insidious spectres of fake news and disinformation—a struggle as fervent and consequential as any historical skirmish over the dominion of truth and influence.
Let us delve into a few case studies that illustrate the multifaceted nature of this digital warfare, where the stakes are nothing less than the integrity of public discourse and the sanctity of societal harmony.
Case 1: A Chief Minister's Stand Against Digital Deception
In the northeastern reaches of India, Assam's Chief Minister, Himanta Biswa Sarma, confronted disinformation head-on. With the spectre of elections looming like a storm on the horizon, he took to the microblogging site X to unveil a nefarious scheme—a doctored video intended to distort his speech and sow seeds of communal discord. 'See for yourself, as elections approach, how vested groups distort a speech with the criminal intention of spreading disinformation and communal disharmony. The long arms of the law will catch up with these elements,' declared Sarma, his words a clarion call for vigilance.
The counterfeit video, crafted to smear the Chief Minister's reputation, elicited a swift and decisive response from Assam's Director General of Police, G.P. Singh. 'Noted Sir. CID Assam would register a criminal case and investigate the people behind this,' assured Singh, signalling the readiness of the law to pursue the purveyors of falsehood.
Case 2: Waves of Deceit: Unverified Claims of Cancellations in the Maldives Tourism Controversy
The narrative shifts to the idyllic archipelago of the Maldives, where the azure waters belie a tumultuous undercurrent of diplomatic discord with India. Following disparaging remarks by Maldivian officials directed at Indian Prime Minister Narendra Modi, the social media sphere became rife with claims of Indian tourists en masse cancelling their sojourns to the island nation. Screenshots purporting to show cancelled bookings flooded platforms like X, with one user claiming to have annulled a reservation at the Palms Retreat, Fulhadhoo, to the tune of at least Rs 5 lakh, citing the officials' 'racist remarks.'
Initial reports from a few media outlets lent credence to this narrative of widespread cancellations. However, upon closer scrutiny, the veracity of these claims crumbled like a sandcastle at high tide. Concrete evidence to substantiate the alleged boycott was conspicuously absent, and neither travel agencies nor airlines corroborated the supposed trend.
The controversy was inflamed when PM Modi's visit to Lakshadweep, and subsequent social media posts praising the archipelago, spurred Indian users to champion Lakshadweep as an alternative to the Maldives. The vitriolic response from Maldivian ministers, who labelled Modi with derogatory remarks, ignited a firestorm on X, with hashtags like #BoycottMaldives and #MaldivesBoycott trending fervently.
Yet, the truth behind the cacophony of cancellation numbers remains shrouded in ambiguity, with no official acknowledgement from either government and a conspicuous absence of data from the tourism industry.
Case 3: Misinformation Highway: Unraveling the Fabrications in Bollywood's rumours or misinformation: Lies, Thumbnails, and Digital Dalliances
Gaze now turns to the bustling fabricated thumbnails or rumour taglines on uploaded videos on YouTube, where thumbnails emblazoned with tantalising texts beckon viewers with the promise of scandalous revelations. 'Pregnant? Divorced?' they shout, luring millions into their web with the allure of salacious 'news.' Yet, these are but mirages, baseless rumours masquerading as fact, or worse, complete fabrications.
The platform teems with counterfeit narratives and rumours, targeting the luminaries of Bollywood. Factors such as easy content uploading without strict scrutiny, a burgeoning digital footprint, and India's insatiable appetite for celebrity culture have created a fertile ground for the proliferation of such content. It is a testament to the power of the digital age, where anyone with a connection can craft a narrative and cast it into the ether, regardless of its foundation in reality.
We must arm ourselves with discernment and scepticism in this relentless onslaught of misinformation. The digital realm, for all its wonders, is also a battleground where the currency is truth, and the price of negligence is the erosion of our collective understanding. As we navigate this ever-evolving landscape, let us hold fast to the principles of verification and evidence, for they are the compass by which we can chart a course through the maelstrom of misinformation that seeks to engulf us.
Conclusion
In this era of digital enlightenment, it is incumbent upon us to discern the chaff from the wheat, to elevate the discourse beyond the mire of falsehoods. Let us endeavour to foster a digital polity that values truth, champions authenticity, and resolutely stands against the tide of disinformation that threatens to undermine the very fabric of our society.
