Online Retail Store Coupang Suffers South Korea's Worst Data Breach, Leak Linked to Former Employee


33.7 million customer data leaked

Data breach is an unfortunate attack that businesses often suffer. Failing to address these breaches is even worse as it costs businesses reputational and privacy damage. 

A breach at Coupang that leaked the data of 33.7 million customers has been linked to a former employee who kept access to internal systems after leaving the organization. 

About the incident 

The news was reported by the Seoul Metropolitan Police Agency with news agencies after an inquiry that involved a raid on Coupang's offices recently. The firm is South Korea's biggest online retailer. It employs 95,000 people and generates an annual revenue of more than $30 billion. 

Earlier in December, Coupang reported that it had been hit by a data breach that leaked the personal data of 33.7 million customers such as email IDs, names, order information, and addresses.

The incident happened in June, 2025, but the firm found it in November and launched an internal investigation immediately. 

The measures

In December beginning, Coupang posted an update on the breach, assuring the customers that the leaked data had not been exposed anywhere online. 

Even after all this, and Coupang's full cooperation with the authorities, the officials raided the firm's various offices on Tuesday to gather evidence for a detailed enquiry.

Recently, Coupang's CEO Park Dae-Jun gave his resignation and apologies to the public for not being able to stop what is now South Korea's worst cybersecurity breach in history. 

Police investigation 

In the second day of police investigation in Coupang's offices, the officials found that the main suspect was a 43-year old Chinese national who was an employee of the retail giant. The man is called JoongAng, who joined the firm in November 2022 and overlooked the authentication management system. He left the firm in 2024. JoongAng is suspected to have already left South Korea. 

What next?

According to the police, although Coupang is considered the victim, the business and staff in charge of safeguarding client information may be held accountable if carelessness or other legal infractions are discovered. 

Since the beginning of the month, the authorities have received hundreds of reports of Coupang impersonation. Meanwhile, the incident has caused a large amount of phishing activity in the country, affecting almost two-thirds of its population.

AI-Powered Shopping Is Transforming How Consumers Buy Holiday Gifts

 

Artificial intelligence is emerging with a new dimension in holiday shopping for consumers, going beyond search capabilities into a more proactive role in exploration and decision-making. Rather than endlessly clicking through online shopping sites, consumers are increasingly turning to AI-powered chatbots to suggest gift ideas, compare prices, and recommend specialized products they may not have thought of otherwise. Such a trend is being fueled by the increasing availability of technology such as Microsoft Copilot, ChatGPT from OpenAI, and Gemini from Google. With basic information such as a few elements of a gift receiver’s interest, age, or hobbies, personalized recommendations can be obtained which will direct such a person to specialized retail stores or distinct products. 

Such technology is being viewed increasingly as a means of relieving a busy time of year with thoughtfulness in gift selection despite being rushed. Industry analysts have termed this year a critical milestone in AI-enabled commerce. Although figures quantifying expenditures driven by AI are not available, a report by Salesforce reveals that AI-enabled activities have the potential to impact over one-twentieth of holiday sales globally, amounting to an expenditure in the order of hundreds of billions of dollars. Supportive evidence can be derived from a poll of consumers in countries such as America, Britain, and Ireland, where a majority of them have already adopted AI assistance in shopping, mainly for comparisons and recommendations. 

Although AI adoption continues to gain pace, customer satisfaction with AI-driven retail experiences remains a mixed bag. With most consumers stating they have found AI solutions to be helpful, they have not come across experiences they find truly remarkable. Following this, retailers have endeavored to improve product representation in AI-driven recommendations. Experts have cautioned that inaccurate or old product information can work against them in AI-driven recommendations, especially among smaller brands where larger rivals have an advantage in resources. 

The technology is also developing in other ways beyond recommenders. Some AI firms have already started working on in-chat checkout systems, which will enable consumers to make purchases without leaving the chat interface. OpenAI has started to integrate in-checkout capabilities into conversations using collaborations with leading platforms, which will allow consumers to browse products and make purchases without leaving chat conversations. 

However, this is still in a nascent stage and available on a selective basis to vendors approved by AI firms. The above trend gives a cause for concern with regards to concentration in the market. Experts have indicated that AI firms control gatekeeping, where they get to show which retailers appear on the platform and which do not. Those big brands with organized product information will benefit in this case, but small retailers will need to adjust before being considered. On the other hand, some small businesses feel that AI shopping presents an opportunity rather than a threat. Through their investment in quality content online, small businesses hope to become more accessible to AI shopping systems without necessarily partnering with them. 

As AI shopping continues to gain popularity, it will soon become important for a business to organize information coherently in order to succeed. Although AI-powered shopping assists consumers in being better informed and making better decisions, overdependence on such technology can prove counterproductive. Those consumers who do not cross-check the recommendations they receive will appear less well-informed, bringing into focus the need to balance personal acumen with technology in a newly AI-shaped retail market.

Trump Approves Nvidia AI Chip Sales to China Amid Shift in U.S. Export Policy


It was the Trump administration's decision to permit Nvidia to regain sales of one of its more powerful artificial intelligence processors to Chinese buyers that sparked a fierce debate in Washington, underscoring the deep tensions between national security policy and economic strategy. 

It represents one of the most significant reversals of U.S. technology export controls in recent history, as the semiconductor giant has been allowed to export its H200 artificial intelligence chips to China, which are the second most advanced chips in the world. 

The decision was swiftly criticized by China hardliners and Democratic lawmakers, who warned that Beijing could exploit the advanced computing capabilities of the country to speed up military modernization and surveillance. 

It was concluded by administration officials, however, that a shift was justified after months of intensive negotiations with industry executives and national security agencies. Among the proposed measures, the U.S. government agreed that economic gains from the technology outweighed earlier fears that it would increase China's technological and military ambitions, including the possibility that the U.S. government would receive a share of its revenues resulting from the technology. 

A quick response from the financial markets was observed when former President Donald Trump announced the policy shift on his Truth Social platform on his morning show. Shares of Nvidia soared about 2% after hours of trading after Trump announced the decision, adding to a roughly 3% gain that was recorded earlier in the session as a result of a Semafor report. 

The president of China, Xi Jinping, said he informed him personally that the move was being made, noting that Xi responded positively to him, a particularly significant gesture considering that Nvidia's chips are being scrutinized by Chinese regulators so closely. 

Trump also noted that the U.S. Commerce Department has been in the process of formalizing the deal, and that the same framework is going to extend to other U.S. chip companies as well, including Advanced Micro Devices and Intel. 

As part of the deal, the United States government will be charged a 25 percent government tax, a significant increase from the 15 percent proposed earlier this year, which a White House official confirmed would be collected as an import tax from Taiwan, where the chips are manufactured, before they are processed for export to China, as a form of security. 

There was no specific number on how many H200 chips Trump would approve or detail what conditions would apply to the shipment, but he said the shipment would proceed only under safeguards designed to protect the national security of the US. 

Officials from the administration described the decision as a calculated compromise, in which they stopped short of allowing exports of Nvidia's most advanced Blackwell chips, while at the same time avoiding a complete ban that could result in a greater opportunity for Chinese companies such as Huawei to dominate the domestic AI chip market. 

NVIDIA argued that by offering H200 processors to vetted commercial customers approved by the Commerce Department, it strikes a “thoughtful balance” between American interests and the interests of the companies. Intel declined to comment and AMD and the Commerce Department did not respond to inquiries. 

When asked about the approval by the Chinese foreign ministry, they expressed their belief that the cooperation should be mutually beneficial for both sides. Among the most important signals that Trump is trying to loosen long-standing restrictions on the sale of advanced U.S. artificial intelligence technology to Chinese countries is his decision, which is widely viewed as a clear signal of his broader efforts. During this time of intensifying global competition, it is a strategic move aimed at increasing the number of overseas markets for American companies. 

In an effort to mend relations among the two countries, Washington has undergone a significant shift in the way it deals with Beijing's controls on rare earth minerals, which provide a significant part of the raw materials for high-tech products in the United States and abroad. 

Kush Desai, a White House spokesperson, said that the administration remains committed to preserving American dominance in artificial intelligence, without compromising national security, as Chinese Embassy spokesperson Liu Pengyu urged the United States to take concrete steps to ensure that global supply chains are stable and work efficiently. 

Despite requests for comment, the Commerce Department, which oversees export controls, did not respond immediately to my inquiries. Trump’s decision marks a sharp departure from his first term, when he aggressively restricted Chinese access to U.S. technology, which received international attention.

China has repeatedly denied allegations that it has misappropriated American intellectual property and repurposed commercial technology for military purposes-claims which Beijing has consistently denied. There is now a belief among senior administration officials that limiting the export of advanced AI chips could slow down the rise of domestic Chinese rivals because it would reduce companies such as Huawei's incentive to develop competing processors, thus slowing their growth. 

According to David Sacks, the White House's AI policy lead, the approach is a strategic necessity, stating that if Chinese chips start dominating global markets, it will mean a loss of U.S. technological leadership.

Although Stewart Baker, a former senior official at the Department of Homeland Security and the National Security Agency, has argued this rationale is extremely unpopular across Washington, it seems unlikely that China will remain dependent on American chips for years to come. According to Baker, Beijing will inevitably seek to displace American suppliers by developing a self-sufficient industry. 

Senator Ron Wyden, a democratic senator who argued that Trump struck a deal that undermined American security interests, expressed similar concerns in his remarks and Representative Raja Krishnamoorthi, who called it a significant national security mistake that benefits America’s foremost strategic rival. 

There are, however, those who are China hawks who contend that the practical impact may be more limited than others. For example, James Mulvenon, a longtime Chinese military analyst, who was consulted by the U.S. government when the sanctions against Chinese chipmakers SMIC were imposed. In total, the decision underscores the fact that artificial intelligence hardware has become an important tool in both economic diplomacy and strategic competition. 

The administration has taken a calibrated approach to exports by opening a narrow channel while maintaining strict limits on the most advanced technologies. Even though the long-term consequences of this move remain uncertain, it has maintained a balanced approach that seeks to balance commercial interest with security considerations.

In order for U.S. policymakers to ensure that well-established oversight mechanisms keep pace with rapid advances in chip capabilities, it will be important to ensure that they prevent the use of such devices for unintended reasons such as military or spying, while maintaining the competitiveness of American firms abroad. 

There is no doubt that the episode demonstrates the growing need to take geopolitical risks into account when planning and executing product, supply chain, and investment decisions in the industry. It also signals that lawmakers are having a broader conversation about whether export controls alone can shape technological leadership in an era of rapid technological advances.

The outcome of the ongoing battle between Washington and Beijing is unlikely to simply affect the development of artificial intelligence, but it is likely to also determine the rules that govern how strategic technologies are transferred across borders—a matter that will require sustained attention beyond the immediate reaction of the market.

Cybercriminals Exploit Law Enforcement Data Requests to Steal User Information

 

While most of the major data breaches occur as a result of software vulnerabilities, credit card information theft, or phishing attacks, increasingly, identity theft crimes are being enacted via an intermediary source that is not immediately apparent. Some of the biggest firms in technology are knowingly yielding private information to what they believe are lawful authorities, only to realize that the identity thieves were masquerading as such.  

Technology firms such as Apple, Google, and Meta are mandated by law to disclose limited information about their users to the relevant law enforcement agencies in given situations such as criminal investigations and emergency situations that pose a threat to human life or national security. Such requests for information are usually channeled through formal systems, with a high degree of priority since they are often urgent. All these companies possess detailed information about their users, including their location history, profiles, and gadget data, which is of critical use to law enforcement. 

This process, however, has also been exploited by cybercriminals. These individuals try to evade the security measures that safeguard data by using law enforcement communication mimicking. One of the recent tactics adopted by cyber criminals is the acquisition of typosquatting domains or email addresses that are almost similar to law enforcement or governmental domains, with only one difference in the characters. These malicious parties then send sophisticated emails to companies’ compliance or legal departments that look no different from law enforcement emails. 

In more sophisticated attacks, the perpetrators employ business email compromise to break into genuine email addresses of law enforcement or public service officials. Requests that appear in genuine email addresses are much more authentic, which in turn multiplies the chances of companies responding positively. Even though this attack is more sophisticated, it is also more effective since it is apparently coming from authentic sources. These malicious data requests can be couched in the terms of emergency disclosures, which could shorten the time for verification. 

This emergency request is aimed at averting real damage that could occur immediately, but the attacker takes advantage of the urgency in convincing companies to disclose information promptly. Using such information, identity theft, money fraud, account takeover, or selling on dark markets could be the outcome. Despite these dangers, some measures have been taken by technology companies to ensure that their services are not abused. Most of the major companies currently make use of law enforcement request portals that are reviewed internally before any data sharing takes place. Such requests are reviewed for their validity, authority, and compliance with the law before any data is shared. 

This significantly decreased the number of cases of data abuse but did not eradicate the risk. As more criminals register expertise in impersonation schemes that exploit trust-based systems, it is evident that the situation also embodies a larger challenge for the tech industry. It is becoming increasingly difficult to ensure a good blend of legal services to law-enforcement agencies with the need to safeguard the privacy of services used by users. Abuse of law-enforcement data request systems points to the importance of ensuring that sensitive information is not accessed by criminals.

Gartner Warns: Block AI Browsers to Avert Data Leaks and Security Risks

 

Analyst company Gartner has issued a recommendation to block AI-powered browsers to help organizations protect business data and cybersecurity. The company says most of these agentic browsers—browsers using autonomous AI models for interacting with web content and automating tasks by default—are designed to provide good user experiences at the cost of compromising security. 

These, the company warns, may leak sensitive information, such as credentials, bank details, or emails, to malicious websites or unauthorized parties. While browsers like OpenAI's ChatGPT Atlas can summarize content, gather data, and automatically navigate users between different websites, the cloud-based back ends commonly used by such browsers handle and store user data, leaving it exposed unless their security settings are carefully managed and appropriate measures implemented. 

What Gartner analysts mean here is that agentic browsers can be deceived into collecting and sending sensitive data to unauthorized parties, especially when workers have confidential data open in browser tabs while using an AI assistant. Furthermore, even if the backend of a browser conforms to the cybersecurity policies of a firm, improper use or configuration may turn the situation very risky. 

The analysts highlight that in all cases, the responsibility lies squarely with each organization to determine the compliance and risks involved with backend services for any AI browser. Besides, Gartner cautions that workers will be tempted to automate mundane or mandated activities, such as cybersecurity training, with the browsers, which could circumvent basic security protocols. 

Safety tips 

To mitigate these risks, Gartner suggests organizations train users on the hazards of exposing sensitive data to AI browser back ends and ensure users do not use these tools while viewing highly confidential information. 

"With the rise of AI, there is a growing tension between productivity and security, as most AI browsers today err toward convenience over safety. I would not recommend complete bans but encourage organizations to perform risk assessments on specific AI services powering the browsers," security expert Javvad Malik of KnowBe4 commented. 

Tailored playbooks for the adoption, oversight, and management of risk for AI agents should be developed to enable organizations to harness the productivity benefits of AI browsers while sustaining appropriate cybersecurity postures.

AI Browsers Raise Privacy and Security Risks as Prompt Injection Attacks Grow

 

A new wave of competition is stirring in the browser market as companies like OpenAI, Perplexity, and The Browser Company aggressively push to redefine how humans interact with the web. Rather than merely displaying pages, these AI browsers will be engineered to reason, take action independently, and execute tasks on behalf of end users. At least four such products, including ChatGPT's Atlas, Perplexity's Comet, and The Browser Company's Dia, represent a transition reminiscent of the early browser wars, when Netscape and Internet Explorer battled to compete for a role in the shaping of the future of the Internet. 

Whereas the other browsers rely on search results and manual navigation, an AI browser is designed to understand natural language instructions and perform multi-step actions. For instance, a user can ask an AI browser to find a restaurant nearby, compare options, and make a reservation without the user opening the booking page themselves. In this context, the browser has to process both user instructions and the content of each of the webpages it accesses, intertwining decision-making with automation. 

But this capability also creates a serious security risk that's inherent in the way large language models work. AI systems cannot be sure whether a command comes from a trusted user or comes with general text on an untrusted web page. Malicious actors may now inject malicious instructions within webpages, which can include uses of invisible text, HTML comments, and image-based prompts. Unbeknownst to them, that might get processed by an AI browser along with the user's original request-a type of attack now called prompt injection. 

The consequence of such attacks could be dire, since AI browsers are designed to gain access to sensitive data in order to function effectively. Many ask for permission to emails, calendars, contacts, payment information, and browsing histories. If compromised, those very integrations become conduits for data exfiltration. Security researchers have shown just how prompt injections can trick AI browsers into forwarding emails, extracting stored credentials, making unauthorized purchases, or downloading malware without explicit user interaction. One such neat proof-of-concept was that of Perplexity's Comet browser, wherein the researchers had embedded command instructions in a Reddit comment, hidden behind a spoiler tag. When the browser arrived and was asked to summarise the page, it obediently followed the buried commands and tried to scrape email data. The user did nothing more than request a summary; passive interactions indeed are enough to get someone compromised. 

More recently, researchers detailed a method called HashJack, which abuses the way web browsers process URL fragments. Everything that appears after the “#” in a URL never actually makes it to the server of a given website and is only accessible to the browser. An attacker can embed nefarious commands in this fragment, and AI-powered browsers may read and act upon it without the hosting site detecting such commands. Researchers have already demonstrated that this method can make AI browsers show the wrong information, such as incorrect dosages of medication on well-known medical websites. Though vendors are experimenting with mitigations, such as reinforcement learning to detect suspicious prompts or restricting access during logged-out browsing sessions, these remain imperfect. 

The flexibility that makes AI browsers useful also makes them vulnerable. As the technology is still in development, it shows great convenience, but the security risks raise questions of whether fully trustworthy AI browsing is an unsolved problem.

Asus Supplier Breach Sparks Security Concerns After Everest Ransomware Claims Data Theft

 

Asus has confirmed a security breach via one of its third-party suppliers after the Everest ransomware group claimed it had accessed internal materials belonging to the company. In its statement, Asus confirmed that a supply chain vendor "was hacked," and the intrusion impacted portions of the source code relating to cameras for Asus smartphones. The company emphasized that no internal systems, products, or customer data were impacted. It refused to name the breached supplier or detail exactly what was accessed, but it said it is shoring up supply chain defenses to align with cybersecurity best practices. 

The disclosure comes amid brazen claims from the Everest ransomware gang, an established extortion outfit that has traditionally targeted major technology firms. Everest claimed it had pilfered around 1 TB of data related to Asus, ArcSoft, and Qualcomm, leaking screenshots online as evidence of the breach. The group said on its dark-web leak site that it was offering an array of deep technical assets, from segmentation modules to source code, RAM dumps, firmware tools, AI model weights, image datasets, crash logs, and test applications. The cache supposedly also contained calibration files, dual-camera data, internal test videos, and performance evaluation reports, the gang said. 

As it is, Asus hasn't verified the broader claims of Everest and has called the incident isolated to a single external supplier that holds camera-related resources. The company hasn't provided an explanation of whether material that was supposedly exfiltrated by the attackers included its proprietary code or information from the other organizations named by the group. Requests for additional comment from the manufacturer went unreturned, thus leaving various aspects of the breach unexplained. The timing is problematic for Asus, coming just weeks after new research highlighted yet another security issue with the company's consumer networking hardware. Analysts in recent weeks said about 50,000 Asus routers were compromised in what observers believe is a China-linked operation. 

That campaign involved attackers exploiting firmware vulnerabilities to build a relatively large botnet that's able to manipulate traffic and facilitate secondary infections. Although the router exploitation campaign and the supplier breach seem unrelated, taken together the two incidents raise the temperature on Asus' overall security posture. With attackers already targeting its networking devices en masse, the discovery of a supply chain intrusion-one that may have entailed access to source code-only adds to the questions about the robustness of the company's development environments. 

As supply chain compromises remain one of the biggest risks facing the tech sector, the incident serves as a reminder of the need for far better oversight, vetting of vendors, and continuous monitoring to ensure malicious actors do not penetrate upstream partners. For Asus, the breach raises pressure on the company to reassure customers and partners that its software and hardware ecosystems remain secure amid unrelenting global cyberthreat activity.

December Patch Tuesday Brings Critical Microsoft, Notepad++, Fortinet, and Ivanti Security Fixes

 


While December's Patch Tuesday gave us a lighter release than normal, it arrived with several urgent vulnerabilities that need attention immediately. In all, Microsoft released 57 CVE patches to finish out 2025, including one flaw already under active exploitation and two others that were publicly disclosed. Notably, critical security updates also came from Notepad++, Ivanti, and Fortinet this cycle, making it particularly important for system administrators and enterprise security teams alike. 

The most critical of Microsoft's disclosures this month is CVE-2025-62221, a Windows Cloud Files Mini Filter Driver bug rated 7.8 on the CVSS scale. It allows for privilege escalation: an attacker who has code execution rights can leverage the bug to escalate to full system-level access. Researchers say this kind of bug is exploited on a regular basis in real-world intrusions, and "patching ASAP" is critical. Microsoft hasn't disclosed yet which threat actors are actively exploiting this flaw; however, experts explain that bugs like these "tend to pop up in almost every big compromise and are often used as stepping stones to further breach". 

Another two disclosures from Microsoft were CVE-2025-54100 in PowerShell and CVE-2025-64671, impacting GitHub Copilot for JetBrains. Although these are not confirmed to be exploited, they were publicly disclosed ahead of patching. Graded at 8.4, the Copilot vulnerability would have allowed for remote code execution via malicious cross-prompt injection, provided a user is tricked into opening untrusted files or connecting to compromised servers. Security researchers expect more vulnerabilities of this type to emerge as AI-integrated development tools expand in usage. 

But one of the more ominous developments outside Microsoft belongs to Notepad++. The popular open-source editor pushed out version 8.8.9 to patch a weakness in the way updates were checked for authenticity. Attackers were managing to intercept network traffic from the WinGUp update client, then redirecting users to rogue servers, where malicious files were downloaded instead of legitimate updates. There are reports that threat groups in China were actively testing and exploiting this vulnerability. Indeed, according to the maintainer, "Due to the improper update integrity validation, an adversary was able to manipulate the download"; therefore, users should upgrade as soon as possible. 

Fortinet also patched two critical authentication bypass vulnerabilities, CVE-2025-59718 and CVE-2025-59719, in FortiOS and several related products. The bugs enable hackers to bypass FortiCloud SSO authentication using crafted SAML messages, which only works if SSO has been enabled. Administrators are advised to disable the feature until they can upgrade to patched builds to avoid unauthorized access. Rounding out the disclosures, Ivanti released a fix for CVE-2025-10573, a severe cross-site scripting vulnerability in its Endpoint Manager. The bug allows an attacker to register fake endpoints and inject malicious JavaScript into the administrator dashboard. Viewed, this could serve an attacker full control over the session without credentials. There has been no observed exploitation so far, but researchers warn that it is likely attackers will reverse engineer the fix soon, making for a deployment environment of haste.
