However, with advancements in technology and analytics, the industry is now shifting toward a proactive approach, emphasizing prevention through real-time monitoring and intelligent threat detection. <a href="https://www.chainalysis.com/product/hexagate/" rel="nofollow">Chainalysis Hexagate</a> brings this shift to life, using pattern recognition and machine learning (ML) to detect decentralized finance (DeFi) hack activity before it occurs.Keep reading to learn more about evolving trends in DeFi hacks and several risky events thus far in 2025 that Chainalysis Hexagate identified before exploits occurred.<h2>Ethereum smart contract events: How many appear malicious?</h2>Every year, more than five million smart contracts are created on the Ethereum blockchain, approximately 20% (one million) of which are actively used on an annual basis. In Q1 2025 alone, nearly 6.2 million new smart contracts were created, surpassing the total amount created in 2024. This number reflects the network’s expanding use across DeFi, gaming, and beyond.<img src="https://static.fwimg.io/img/feed/4a8f91c01461fc8598c0587937c65792.jpg" alt="">Between January and March 2025, there were 261,000 unique events emitted on Ethereum, with approximately 20% actively used on an annual basis (52,200). On Ethereum, emitting an event refers to a smart contract logging a specific action on the blockchain. Events are commonly used to record important steps in a transaction, such as a token being transferred or a swap taking place. Overall, the lack of active events emitted suggests a massive surface area of potentially obscure or risky activity, as legitimate smart contracts are typically deployed more regularly.As we see in the below chart, the most frequently emitted event on Ethereum thus far in 2025 has been Transfer, which occurs when <a href="https://www.chainalysis.com/blog/introduction-to-erc-20-tokens/" rel="nofollow">ERC-20 tokens</a> are transferred between addresses. This event is the basic building block for any token-based activity, including payments, rewards, and user interactions.Other frequently observed events come from DeFi contracts and include:<ul><li>Swap: Triggered when a user exchanges one token for another on a decentralized exchange (DEX).</li><li>Approval: Occurs when a user gives permission to a contract to spend their tokens.</li></ul><ul><li>Sync: Used by liquidity pools to update price or reserve ratios.</li></ul><ul><li>Deposit: Indicates that a user has added funds to a contract, often in the context of staking or providing liquidity.</li></ul><img src="https://static.fwimg.io/img/feed/220f416e22fb7e5e251ab4b0c22b3d58.jpg" alt="">According to Chainalysis Hexagate data, risky events on Ethereum represent only 0.2% of total events emitted in 2025. Risky events include Initialized, RoleGranted, and RemovedOwner, which Chainalysis Hexagate has identified as high-risk signatures.The “Initialized” event is typically emitted when a smart contract becomes operational and signals that the contract has been assigned its initial configuration. The “RoleGranted” event indicates that a specific address has been assigned a defined role within a smart contract’s access control structure. And the “RemoveOwner” event is triggered when an address with ownership or administrative rights is removed from a contract’s list of authorized controllers.<img src="https://static.fwimg.io/img/feed/879644face9f5d799b543c8ea8b3a229.jpg" alt="">Although rare, these events typically lead to major losses and therefore require close monitoring to ensure that legitimate users are not put at risk. Chainalysis Hexagate utilizes real-time monitoring of these events and machine learning models to proactively identify and mitigate potential threats.<h2>Chainalysis Hexagate can detect threats before they occur</h2>In the first quarter of 2025, Chainalysis Hexagate’s machine learning model flagged more than $402.1 million in risky assets tied to malicious activity, with amounts surging 60.71% between February and March. This type of activity includes assets stolen from DeFi, centralized exchanges (CEXs), and token smart contracts.<img src="https://static.fwimg.io/img/feed/124366b0cbe41ce114dd9502edb4ca9c.jpg" alt="">Given the rise in <a href="https://www.chainalysis.com/blog/preventing-authorized-push-payment-fraud-in-crypto/" rel="nofollow">phishing attacks</a>, it’s crucial to dig deeper into the above topline figures to understand just how much of the malicious activity can be traced back to phishing schemes specifically. Between January and March 2025, approximately 18,000 phishing tokens were created. Each month, phishing tokens impact more than 50 million wallets; in March 2025 alone, 400,000 services were affected.<img src="https://static.fwimg.io/img/feed/a6d682acf28a07d4065dd3efc0a5501c.jpg" alt=""><h2>A growing threat surface in 2025: DPRK-linked attacks and volume of on-chain exploits</h2>Crypto’s expanding footprint in 2025 has been met with a surge in sophisticated exploit attempts across the ecosystem. Evidence of this growing threat includes the scale of DPRK-linked thefts and the significance of the top 10 attacks identified by Chainalysis Hexagate.As we reported in our <a href="https://www.chainalysis.com/blog/crypto-hacking-stolen-funds-2025/" rel="nofollow">2025 Crypto Crime Report</a>, North Korea-linked hackers stole more from crypto platforms than ever before in 2024. Unfortunately, stolen funds linked to the DPRK are continuing to grow — 2025 numbers are already trending higher than those of 2024 and have surpassed $1 billion.<img src="https://static.fwimg.io/img/feed/46f171a0784f61fe2d30e1ba8243a605.jpg" alt="">Additionally, the volume and complexity of on-chain exploits are increasing monthly — Chainalysis Hexagate’s detection volume doubled from January to March 2025. In the chart below, we see the top 10 hacks in Q1 2025, all of which were detected by Chainalysis Hexagate as potentially risky before the exploits occurred. Although many of these events were not disrupted in real-time, they provide an important reminder for Hexagate users to increase their defenses against malicious attacks.<img src="https://static.fwimg.io/img/feed/8f16f552a664571ba512ebc5f2f920e0.jpg" alt=""><h2>Staying ahead of evolving crypto-related threats</h2>Malicious on-chain activity is becoming more frequent and more complex. From phishing schemes to social engineering exploits, threat actors in 2025 are adapting quickly — and so must the defenses. As these tactics evolve, the need for proactive, real-time protection has never been more urgent. Chainalysis Hexagate helps fill that gap, using machine learning and on-chain intelligence to stop exploits before they escalate.Book a demo of Chainalysis Hexagate’s security solution <a href="https://www.chainalysis.com/request-a-demo/" rel="nofollow">here</a>.This website contains links to third-party sites that are not under the control of Chainalysis, Inc. or its affiliates (collectively “Chainalysis”).

패턴 인식 및 머신 러닝을 활용한 Chainalysis Hexagate로 DeFi 해킹 이벤트 방지

오늘 금, 은, 팔라듐 가격이 모두 사상 최고치를 경신했습니다! 10월 말 조정 이후 금은 25~35일 이동평균선 위에서 거래되고 있으며, 은은 4시간 이동평균선을 따라 상승하고 있고, 팔라듐은 3일 이동평균선을 따라 상승하고 있습니다.
동기화: 이러한 "동시적인 신고가 경신"은 일반적으로 주요 추세의 시작을 의미합니다. 금은 "안정성"을, 은은 "탄력성"을 제공하며, 팔라듐의 추가는 산업 및 투자 수요의 동시 급증을 나타냅니다.
이처럼 뚜렷한 상승 추세 속에서 거래량은 크게 감소하지 않았으며, 공매도(Short) 추세를 나타내는 신호도 나타나지 않았습니다. 최고점에서 숏(Short) 시도하지 마십시오. 그렇지 않으면 큰 손실을 볼 수 있습니다.

시장 분석 | 금, 은, 팔라듐이 사상 최고치를 경신했습니다! 어디까지 오를 수 있을까요!?

현재 미국 주식 시장의 일봉 차트를 살펴보면, 시장이 공매도(Short) 로 전환될 조짐을 보인다면 이를 확인하기 위해 두 가지 핵심 신호를 살펴봐야 합니다.
- 주요 지지선 하향 돌파: 3대 주요 지수 모두 빨간색 선 아래로 떨어져야 합니다.
- 구조적 반전: 추세는 더 낮은 고점과 더 낮은 저점을 보여야 합니다.
전반적인 추세는 여전히 상승, 아직 최고점을 경신하지 못했기 때문에 10월 30일 이후로는 사실상 횡보세를 보이고 있습니다.
마켓펄스 데이터에 따르면 현재 지수는 약 50 수준입니다.
