North Korean state-sponsored hackers have just executed one of the most shocking moves in crypto news history by officially weaponizing blockchain technology, hiding dangerous malware inside smart contracts on BNB Smart Chain and Ethereum to steal cryptocurrency. This isn't just another ordinary cyber attack, it marks the first time in history that a nation-state actor has officially deployed the EtherHiding technique to distribute malware, creating a wave of deep concern throughout the global cryptocurrency investment community and crypto trading platforms worldwide. With over $2 billion already stolen in 2025 alone, this blockchain news is forcing crypto investors and digital asset security experts to completely reconsider their protection strategies.
Google's Threat Intelligence Group has announced a breakthrough discovery about the hacker group UNC5342 with close ties to North Korea, who are deploying an attack campaign dubbed "Contagious Interview" targeting cryptocurrency developers and technology professionals. The alarming aspect of this cryptocurrency market news is that they began using the EtherHiding technique in February 2025, allowing them to hide JavaScript malware inside smart contracts on BNB Smart Chain and Ethereum in a completely unremovable manner. UNC5342's sophisticated attack toolkit includes a JavaScript downloader named JADESNOW, designed to fetch and execute the INVISIBLEFERRET backdoor directly from data stored in blockchain smart contracts.
According to real-time data from the cryptocurrency market today, Bitcoin is trading at $107, 156 USD on October 19, 2025, up 0.67% from yesterday and up 56.51% year-over-year. Meanwhile, Ethereum price today has reached approximately $3, 890 USD, showing the market maintains strong recovery momentum despite escalating security risks. This leads crypto market analysts to conclude that investors need to balance profit opportunities with digital asset wallet protection measures against these new threats.

The EtherHiding technique's operating mechanism in this cryptocurrency news is particularly dangerous because it exploits blockchain's immutable nature. Smart contracts once deployed on networks like BNB Smart Chain or Ethereum cannot be deleted, creating a permanent malware repository that security experts cannot remove. What's even more concerning in the current crypto news context is that read-only calls to the blockchain don't create new transactions or leave traces in blockchain analysis tools, making detection and prevention extremely difficult.
The UNC5342 group has cleverly exploited this mechanism by updating or changing malware payloads through overwriting storage variables in on-chain smart contracts, all happening without needing to re-infiltrate distribution pages or customer devices. While previous blockchain news recorded attackers motivated by financial gain using similar infrastructure, this is the first time Google has witnessed a state-sponsored group integrating this technique into their operational toolkit.
Google's report links this blockchain infrastructure to actual attacks distributed via compromised WordPress sites and social engineering lures, including fake job interviews designed to attract crypto developers. Victims accessing these websites receive the JADESNOW loader, which then connects to on-chain smart contracts, retrieves the JavaScript payload and runs it locally on their computers. This payload subsequently launches INVISIBLEFERRET, a full-featured backdoor with remote control capabilities enabling long-term espionage operations and data theft.
According to research from Cisco Talos, recent campaigns also show integration between BeaverTail and OtterCookie, two complementary malware strains frequently used by the North Korea-linked Famous Chollima group. These tools not only target cryptocurrency wallet theft but also collect login credentials and private data stored in browsers. The sophisticated nature of these attacks represents a significant evolution in blockchain security threats that the cryptocurrency investment community must understand and defend against.

In this crypto news context, intelligence agencies and the United Nations have warned that stolen cryptocurrency is directly funding North Korea's nuclear and missile programs, increasing pressure for stricter international cryptocurrency regulations. Blockchain analytics company Elliptic reports that North Korea-linked hacker groups have stolen over $2 billion in crypto assets in 2025, the highest figure ever recorded with three months still remaining in the year.
This $2 billion figure is nearly triple last year's total and exceeds the previous record of $1.35 billion set in 2022. The Bybit exchange hack in February 2025 with $1.46 billion accounted for the majority of this total, becoming one of the largest recorded crypto thefts. Additionally, Elliptic attributes attacks on LND. Fi, WOO X, and Seedify this year to North Korea, along with over 30 additional incidents involving smaller exchanges and DeFi platforms.
With Bitcoin and promising altcoin projects attracting increasingly more investors, understanding these security threats becomes extremely important. Experts on reputable cryptocurrency trading platforms recommend users should only purchase through licensed and fully regulated platforms with strong track records. Binance , one of the world's largest crypto exchanges, has continuously upgraded security measures to counter these increasingly sophisticated threats.
Although Google didn't specify how smart contract data is retrieved, previous research on EtherHiding has shown attackers typically rely on standard JSON-RPC calls, which can go through public or hosted infrastructure. Blocking these services or forcing customers to use self-hosted nodes with policy restrictions could provide temporary blocking solutions. On the browser side, organizations can enforce strict extension and script execution policies, while locking update processes to prevent fake Chrome-type alerts from spreading.

For those learning how to invest in cryptocurrency for beginners, this latest Bitcoin news today serves as an important reminder about security's critical importance. Experts recommend never downloading software from unclear sources, especially when receiving job offers or attractive investment opportunities via email or messages. Using hardware wallets is considered one of the most effective protection measures for personal crypto assets.
In today's cryptocurrency market, Bitcoin price predictions this week show a slight upward trend with fluctuations ranging from $105, 000 to $110, 000 USD, while Ethereum price forecasts this week may fluctuate between $3, 800 to $4, 200 USD. Smart investors are taking advantage of this opportunity to accumulate more assets while maintaining strict security measures. Choosing reputable crypto trading platforms domestically or internationally like Binance is the first crucial step to protecting your investment.
Research from blockchain security companies shows 2025 is witnessing a significant increase in attack sophistication levels. Beyond 51% attacks, blockchain endpoint vulnerabilities, and routing attacks, the crypto market now faces threats from abusing blockchain technology's very immutable nature. This raises major questions about balancing blockchain's transparency and decentralization with security and control needs.
DeFi and NFT platforms are also in these hacker groups' crosshairs, with dozens of small-scale attacks recorded monthly. BNB Smart Chain recorded an 85% decrease in losses from security incidents in 2023 versus 2022, with $161 million lost across 414 incidents, but new techniques like EtherHiding are creating completely new challenges. This shows the battle between hackers and security experts is an endless arms race.

Google Threat Intelligence Group has played a pivotal role in discovering and warning about this campaign, showing the importance of collaboration between major tech companies and the crypto community. Google's threat tracking and analysis capabilities have helped accurately identify actor groups, attack methods and infrastructure used. However, challenges remain significant when blockchain API service providers don't respond uniformly to requests limiting access from identified malicious actors.
Coordination between blockchain analytics companies like Elliptic, CertiK, and other security platforms with major exchanges is becoming more necessary than ever. Chrome Enterprise tools allow administrators to enforce download restrictions on dangerous file types and manage automatic browser updates, thereby preventing malware installation triggered by fake update pop-ups or deceptive phishing tactics.
Security experts predict using blockchain as a malware distribution medium will continue increasing in coming months. Blockchain's immutability and decentralization make it an ideal repository for attackers wanting long-term control without worrying about infrastructure takedown. Particularly, the ability to flexibly switch between different blockchain networks to store payloads complicates tracking and analysis while reducing operational costs due to lower transaction fees.
The global blockchain community and cryptocurrency investors need regular updates about new attack methods and apply corresponding protection measures. Following latest Bitcoin news today from reputable sources, participating in crypto security courses, and using multi-factor authentication are basic steps every investor should implement.

For individual users, never clicking suspicious links, especially those related to job or investment opportunities in the crypto field, is extremely important.
Reputable crypto exchanges like Binance have deployed multiple security layers including two-factor authentication (2FA), pre-approved withdrawal address lists, and 24/7 abnormal transaction monitoring systems. This is why choosing a reputable domestic or high-credibility international cryptocurrency trading platform is the first and most important step in the safe cryptocurrency investment journey.
The global blockchain community faces an interesting paradox when the very characteristics that make this technology powerful are being exploited for harm. Blockchain's transparency, decentralization and immutability were created to protect users, but now have become tools for cybercriminals. This raises major questions about designing future blockchain protocols that both maintain core characteristics and have capability to resist abuse forms.
Researchers are exploring potential solutions including integrating smart content moderation mechanisms into blockchain nodes, developing more advanced smart contract behavior analysis tools, and creating new security standards for blockchain interaction. However, all solutions must carefully balance security and blockchain technology's fundamental decentralization principles.
As we approach the end of 2025, this year has proven to be a watershed moment in the history of blockchain security and cryptocurrency investment. The emergence of EtherHiding as a nation-state weapon marks a dangerous new chapter where advanced persistent threat actors are no longer just exploiting software vulnerabilities but weaponizing the very architecture of decentralized technology itself. With just three months remaining in 2025, the crypto community stands at a critical juncture where the decisions made today about security protocols, regulatory frameworks, and collaborative defense mechanisms will shape the safety and viability of digital assets for years to come. Looking ahead to 2026, industry experts predict this timeline will be remembered as the year that forced the entire blockchain ecosystem to fundamentally rethink the balance between decentralization ideals and practical security imperatives.
