Instead of relying on a single model, Copilot's Researcher agent can now pull outputs from both OpenAI's GPT and Anthropic's Claude models for each response, thanks to a new feature called "Critique."
According to Microsoft, Claude will check the quality and correctness of the response before GPT provides it to the user. In the future, the business hopes to make that workflow bidirectional so that GPT may also evaluate Claude's writings.
"Having different models from different vendors in Copilot is highly attractive - but we're taking this to the next level, where customers actually get the benefits of the models working together," Nicole Herskowitz, VP of Copilot and Microsoft, said to Reuters.
The multi-model strategy will assist in increasing productivity and quality for customers by accelerating user workflow, controlling AI hallucinations, which occur when systems give incorrect information, and producing more dependable outputs.
Additionally, Microsoft is introducing a feature called "Council" that will let users compare results from various AI models side by side. The updates coincide with Microsoft expanding access to its new Copilot Cowork agentic AI tool for members of its "Frontier" program, which gives users early access to some of its most recent AI innovations.
According to Jared Spataro, Microsoft's AI-at-Work efforts leader, “We work only in a cloud environment, and we work only on behalf of the user. So you know exactly what information it (Copilot Cowork) has access to.”
On Monday, the company's stock increased by almost 1%. However, as investor confidence in AI declines, the stock is poised for its worst quarter since the global financial crisis of 2008, with a nearly 25% decline.
Microsoft capitalized on the increasing demand for autonomous AI agents earlier this month by releasing Copilot Cowork, a solution based on Anthropic's popular Claude Cowork product, in testing mode.
In the face of fierce competition from rivals like Google (GOOGL.O), the new tab Gemini, and autonomous agents like Claude Cowork, the Windows manufacturer has been rushing to enhance its Copilot assistant to promote greater usage.
New research suggests the cryptocurrency industry may have less time than anticipated to prepare for the risks posed by quantum computing, with potential implications for Bitcoin, Ethereum, and other major digital assets.
A whitepaper released on March 31 by researchers at Google indicates that breaking the cryptographic systems securing these networks may require fewer than 500,000 physical qubits on a superconducting quantum computer. This marks a sharp reduction from earlier estimates, which placed the requirement in the millions.
The study brings together contributors from both academia and industry, including Justin Drake of the Ethereum Foundation and Dan Boneh, alongside Google Quantum AI researchers led by Ryan Babbush and Hartmut Neven. The research was also shared with U.S. government agencies prior to publication, with input from organizations such as Coinbase and the Ethereum Foundation.
At present, no quantum system is capable of carrying out such an attack. Google’s most advanced processor, Willow, operates with 105 qubits. However, researchers warn that the gap between current hardware and attack-capable machines is narrowing. Drake has estimated at least a 10% probability that a quantum computer could extract a private key from a public key by 2032.
The concern centers on how cryptocurrencies are secured. Bitcoin relies on a mathematical problem known as the Elliptic Curve Discrete Logarithm Problem, which is considered practically unsolvable using classical computers. However, Peter Shor demonstrated that quantum algorithms could solve this problem far more efficiently, potentially allowing attackers to recover private keys, forge signatures, and access funds.
Importantly, this threat does not extend to Bitcoin mining, which relies on the SHA-256 algorithm. Experts suggest that using quantum computing to meaningfully disrupt mining remains decades away. Instead, the vulnerability lies in signature schemes such as ECDSA and Schnorr, both based on the secp256k1.
The research outlines three potential attack scenarios. “On-spend” attacks target transactions in progress, where an attacker could intercept a transaction, derive the private key, and submit a fraudulent replacement before confirmation. With Bitcoin’s average block time of 10 minutes, the study estimates such an attack could be executed in roughly nine minutes using optimized quantum systems, with parallel processing increasing success rates. Faster blockchains such as Ethereum and Solana offer narrower windows but are not entirely immune.
“At-rest” attacks focus on wallets with already exposed public keys, such as reused or inactive addresses, where attackers have significantly more time. A third category, “on-setup” attacks, involves exploiting protocol-level parameters. While Bitcoin appears resistant to this method, certain Ethereum features and privacy tools like Tornado Cash may face higher exposure.
Technically, the researchers developed quantum circuits requiring fewer than 1,500 logical qubits and tens of millions of computational operations, translating to under 500,000 physical qubits under current assumptions. This is a substantial improvement over earlier estimates, such as a 2023 study that suggested around 9 million qubits would be needed. More optimistic models could reduce this further, though they depend on hardware capabilities not yet demonstrated.
In an unusual move, the team did not publish the full attack design. Instead, they used a zero-knowledge proof generated through the SP1 zero-knowledge virtual machine to validate their findings without exposing sensitive details. This approach, rarely used in quantum research, allows independent verification while limiting misuse.
The findings arrive as both industry and governments begin preparing for a post-quantum future. The National Security Agency has called for quantum-resistant systems by 2030, while Google has set a 2029 target for transitioning its own infrastructure. Ethereum has been actively working toward similar goals, aiming for a full migration within the same timeframe. Bitcoin, however, faces slower progress due to its decentralized governance model, where major upgrades can take years to implement.
Early mitigation efforts are underway. A recent Bitcoin proposal introduces new address formats designed to obscure public keys and support future quantum-resistant signatures. However, a full transition away from current cryptographic systems has not yet been finalized.
For now, users are advised to take precautionary steps. Moving funds to new addresses, avoiding address reuse, and monitoring updates from wallet providers can reduce exposure, particularly for long-term holdings. While the threat is not immediate, researchers emphasize that preparation must begin well in advance, as advances in quantum computing continue to accelerate.
A newly observed version of the Chaos malware is now targeting poorly secured cloud environments, indicating a defining shift in how this threat is being deployed and scaled.
According to analysis by Darktrace, the malware is increasingly exploiting misconfigured cloud systems, moving beyond its earlier focus on routers and edge devices. This change suggests that attackers are adapting to the growing reliance on cloud infrastructure, where configuration errors can expose critical services.
Chaos was first identified in September 2022 by Lumen Black Lotus Labs. At the time, it was described as a cross-platform threat capable of infecting both Windows and Linux machines. Its functionality included executing remote shell commands, deploying additional malicious modules, spreading across systems by brute-forcing SSH credentials, mining cryptocurrency, and launching distributed denial-of-service attacks using protocols such as HTTP, TLS, TCP, UDP, and WebSocket.
Researchers believe Chaos developed from an earlier DDoS-focused malware strain known as Kaiji, which specifically targeted exposed Docker instances. While the exact operators behind Chaos remain unidentified, the presence of Chinese-language elements in the code and the use of infrastructure linked to China suggest a possible connection to threat actors from that region.
Darktrace detected the latest variant within its honeypot network, specifically on a deliberately misconfigured Hadoop deployment that allowed remote code execution. The attack began with an HTTP request sent to the Hadoop service to initiate the creation of a new application.
That application contained a sequence of shell commands designed to download a Chaos binary from an attacker-controlled domain, identified as “pan.tenire[.]com.” The commands then modified the file’s permissions using “chmod 777,” allowing full access to all users, before executing the binary and deleting it from the system to reduce forensic evidence.
Notably, the same domain had previously been linked to a phishing operation conducted by the cybercrime group Silver Fox. That campaign, referred to as Operation Silk Lure by Seqrite Labs in October 2025, was used to distribute decoy documents and ValleyRAT malware, suggesting infrastructure reuse across campaigns.
The newly identified sample is a 64-bit ELF binary that has been reworked and updated. While it retains much of its original functionality, several features have been removed. In particular, capabilities for spreading via SSH and exploiting router vulnerabilities are no longer present.
In their place, the malware now incorporates a SOCKS proxy feature. This allows compromised systems to relay network traffic, effectively masking the origin of malicious activity and making detection and mitigation more difficult for defenders.
Darktrace also noted that components previously associated with Kaiji have been modified, indicating that the malware has likely been rewritten or significantly refactored rather than simply reused.
The addition of proxy functionality points to a broader monetization strategy. Beyond cryptocurrency mining and DDoS-for-hire operations, attackers may now leverage infected systems to provide anonymized traffic routing or other illicit services, reflecting increasing competition within cybercriminal ecosystems.
This shift aligns with a wider trend observed in other botnets, such as AISURU, where proxy services are becoming a central feature. As a result, the threat infrastructure is expanding beyond traditional service disruption to include more complex abuse scenarios.
Security experts emphasize that misconfigured cloud services, including platforms like Hadoop and Docker, remain a critical risk factor. Without proper access controls, attackers can exploit these systems to gain initial entry and deploy malware with minimal resistance.
The continued evolution of Chaos underlines how threat actors are persistently enhancing their tools to expand botnet capabilities. It also reinforces the need for continuous security monitoring, as changes in how APIs and services function may not always appear as direct vulnerabilities but can exponentially increase exposure.
Organizations are advised to regularly audit configurations, restrict unnecessary access, and monitor for unusual behavior to mitigate the risks posed by increasingly adaptive malware threats.
Privacy issues have always bothered users and business organizations. With the rapid adoption of AI, the threats are also rising. DuckDuckGo’s Duck.ai chatbot benefits from this.
The latest report from Similarweb revealed that traffic to Duck.ai increased rapidly last month. The traffic recorded 11.1 million visits in February 2026, 300% more than January.
The statistics seem small when compared with the most popular chatbots such as ChatGPT, Claude, or Gemini.
Similarweb estimates that ChatGPT recorded 5.4 billion visits in February 2026, and Google’s Gemini recorded 2.1 billion, whereas Claude recorded 290.3 million.
For DuckDuckGo, the numbers show a good sign, as the bot was launched as beta in 2025, and has shown a sharp rise in visits.
DuckDuckGo browser is known for its privacy, and the company aims to apply the same principle to its AI bot. Duck.ai doesn't run a bespoke LLM, it uses frontier models from Meta, Anthropic, and OpenAI, but it doesn't expose your IP address and personal data.
Duck.ai's privacy policy reads, "In addition, we have agreements in place with all model providers that further limit how they can use data from these anonymous requests, including not using Prompts and Outputs to develop or improve their models, as well as deleting all information received once it is no longer necessary to provide Outputs (at most within 30 days, with limited exceptions for safety and legal compliance),”
What is the reason for this sudden surge? The bot has two advantages over individual commercial bots like ChatGPT and Gemini, it offers an option to toggle between multiple models and better privacy security. The privacy aspect sets it apart. Users on Reddit have praised Duck.ai, one person noting "it's way better than Google's," which means Gemini.
In March, Anthropic rejected a few applications of its technology for mass surveillance and weapons submitted by the Department of Defense. The DoD retaliated by breaking the contract. Soon after, OpenAI stepped in.
The incident stirred controversies around privacy concerns and ethical AI use. This explains why users may prefer chatbots like Duck.ai that safeguard user data from both the government and the big tech.
A new investigation has uncovered a cyberattack method that uses blockchain networks to quietly distribute malware, raising concerns among security researchers about how difficult it may be to stop once it spreads further.
The threat first surfaced when a senior engineering executive at Crystal Intelligence received a freelance opportunity through LinkedIn. The message appeared routine, asking him to review and run code hosted on GitHub. However, the request resembled a known tactic used by a North Korean-linked group often referred to as Contagious Interview, which relies on fake job offers to target developers.
Instead of proceeding, the executive examined the code and found something unusual. Hidden within it was the beginning of a multi-step attack designed to look harmless. A developer following normal instructions would likely execute it without noticing anything suspicious.
Once activated, the code connects to blockchain networks such as TRON and Aptos, which are commonly used because of their low transaction costs. These networks do not contain the malware itself but instead store information that directs the program to another blockchain, Binance Smart Chain. From there, the final malicious payload is retrieved and executed.
Researchers say this last stage installs a powerful data-stealing tool known as “Omnistealer.” According to analysts working with Ransom-ISAC, the malware is designed to extract a wide range of sensitive data. It can access more than 60 cryptocurrency wallet extensions, including MetaMask and Coinbase Wallet, as well as over 10 password managers such as LastPass. It also targets major browsers like Chrome and Firefox and can pull data from cloud storage services like Google Drive. This means attackers are not just stealing cryptocurrency, but also login credentials and internal access to company systems.
What initially looked like a simple phishing attempt turned out to be far more layered. By placing parts of the attack inside blockchain transactions, the attackers have created a system that is extremely difficult to dismantle. Data stored on blockchains cannot easily be removed, which means parts of this malware infrastructure could remain accessible for years.
Researchers believe the scale of this operation could grow rapidly. Some have compared its potential reach to the WannaCry ransomware attack, which disrupted hundreds of thousands of systems worldwide. In this case, however, the method is quieter and more flexible, which may allow it to spread further before being detected. At the same time, investigators are still unsure what the attackers ultimately intend to do with the access they gain.
Further analysis has revealed possible links to North Korean cyber actors. Investigators traced parts of the activity to an IP address in Vladivostok, a location that has previously appeared in investigations involving North Korean operations. Research cited by NATO has noted that North Korea expanded its internet routing through Russia several years ago. Additional findings from Trend Micro connect similar infrastructure to earlier campaigns involving fake recruiters.
The number of affected victims is already significant. Researchers estimate that around 300,000 credentials have been exposed so far, although they believe the real figure could be much higher. Impacted organizations include cybersecurity firms, defense contractors, financial companies, and government entities in countries such as the United States and Bangladesh.
The attackers rely heavily on deception to gain access. In some cases, they pose as recruiters and convince developers to run infected code as part of a hiring process. In others, they present themselves as freelance developers and introduce malicious code directly into company systems through platforms like GitHub.
Developers in rapidly growing tech ecosystems appear to be a key focus. India, for example, has seen a surge in new contributors on GitHub and ranks among the top countries for cryptocurrency adoption. Researchers suggest that a combination of high developer activity and economic incentives may make such regions more vulnerable to these tactics.
Initial contact is typically made through platforms such as LinkedIn, Upwork, Telegram, and Discord. Representatives from these platforms have advised users to be cautious, particularly when asked to download files or execute unfamiliar code outside controlled environments.
Not all targeted organizations appear strategically important, which suggests the attackers may be casting a wide net. However, the presence of defense and security-related entities among the victims raises more serious concerns about potential intelligence-gathering objectives.
Security experts say this campaign reflects a broader shift in how attacks are being designed. Instead of relying on a single point of failure, attackers are combining social engineering, publicly accessible code platforms, and decentralized infrastructure. The use of blockchain in particular adds a layer of persistence that traditional security tools are not designed to handle.
As investigations continue, researchers warn that this may only be an early stage of a much larger problem. The combination of hidden delivery methods, long-term persistence, and unclear intent makes this campaign especially difficult to predict and contain.
The global threat landscape has shifted from data theft to threats against human lives. The convergence of Operational Technology (OT) and Information Technology (IT) has increased the attack surface, exposing sectors like public utilities, aviation, and transport to outsider risks.
According to Gaurav Shukla, cybersecurity expert at Deloitte South Asia, “For the past two years, we observed that cyber threats were not limited only to the IT systems. They were pervading beyond IT systems, and the perpetrators were targeting more of the critical infrastructure.”
Digital transformation in recent years has increased the attack surface, providing more opportunities for threat actors to compromise critical infrastructure. “
"If you are driving a connected car on a highway at 120 km/h and suddenly find the steering is no longer in your control, you are not going to be worried about how much money is in your bank account. You are worried about the danger to your life,” Shukla added.
For instance, an attack on a medical device compromising patient information can be dangerous, whereas a cyber attack on power grids and the transmission sector can result in countrywide blackouts.
The world population of eight billion is currently surrounded by more than 30 billion IoT sensors. This means that, on average, a person is surrounded by more than 3.5 sensors.
India’s Digital Public Infrastructure, aka India Stack, has become a global benchmark. According to experts, Deloitte has suggested that 24 countries adopt their own framework for the India Stack. Shukla has warned that as DPI reaches beyond identity and payments to include education and healthcare, the convergence points create new threats. DPI accounts for around 80% of India’s digital transactions in January 2026.
Attackers' use of artificial intelligence (AI) increases the speed and scope of their attacks. Thus, ongoing testing against supply chain problems and AI-related risks will be extremely important, he continued.
Cyberwarfare is continuous, demanding ongoing cooperation between businesses, academics, and the government, whereas kinetic wars are time-bound. “Much like you need a language to build a foundation, awareness of cybersecurity and privacy is going to be just as important,” Shukla added.
