El exploit de seguridad en la cadena SagaEVM, ocurrido el 21 de enero, resultó en el robo de aproximadamente 7 millones de dólares en activos, que fueron transferidos en parte a Ethereum. El equipo de Saga detuvo la cadena para evitar más transferencias no autorizadas e identificó la billetera del atacante, colaborando con exchanges para bloquearla y recuperar los fondos. La investigación forense continúa y se publicará un informe técnico completo. Aunque el exploit afectó a SagaEVM y sus entornos asociados, la capa de consenso principal y la seguridad de los validadores no se vieron comprometidas. Paralelamente, un informe de Chainalysis estima que la industria de las criptomonedas perdió más de 3.400 millones de dólares por robos en 2025.

La cadena SagaEVM, parte del ecosistema blockchain de Capa-1 Saga, permaneció pausada tras una explotación de seguridad el 21 de enero. Con ello, la actualización de la investigación se publicó el 22 de enero, se encontró la billetera del atacante y alrededor de $7 millones en activos, con algunos convertidos a Ethereum. Además, el equipo está trabajando para incluir en la lista negra la dirección de ese hacker.

Saga Identifica la Billetera del Atacante Mientras los Fondos se Puentean a Ethereum

Después de que se identificó la explotación, el primer día, el equipo pausó la cadena en la altura de bloque 6,593,800 para detener las transferencias no autorizadas. Además, parece haber involucrado una secuencia de implementaciones de contratos, interacciones cross-chain y retiros rápidos de liquidez que permitieron al atacante extraer activos.

Los activos robados, incluido USDC, fueron transferidos a la red principal de Ethereum y, en algunos casos, convertidos a ETH u otros tokens. Asimismo, Saga ha identificado la billetera vinculada a la explotación y está trabajando con exchanges y operadores de puentes para incluirla en la lista negra y apoyar la recuperación de activos.

Con ello, actualmente, el equipo de Saga está realizando una investigación forense detallada y planea publicar un informe técnico post-mortem exhaustivo.

La explotación afectó a la propia cadena de red SagaEVM, así como a entornos como Colt y Mustang que dependen de la funcionalidad EVM, mientras que la red principal de Saga SSC, la capa de consenso y la seguridad del Validador no se vieron afectadas, y no hubo evidencia de compromiso de claves privadas.

NVIDIA's New Open-Source MoE: One Line of Import, Fine-Tuning Accelerated by 3.7x

NVIDIA has open-sourced NeMo AutoModel, a tool designed to significantly accelerate the fine-tuning of Mixture-of-Experts (MoE) large language models. By adding just one import line to existing code based on Hugging Face Transformers v5, users can achieve a 3.4x to 3.7x increase in training throughput and reduce GPU memory usage by 29% to 32% without altering their API. The key innovations include Expert Parallelism (EP) to distribute expert weights across GPUs, lowering memory pressure; DeepEP to fuse computation and communication; and TransformerEngine kernels for accelerated core operations. Benchmarks on models like Qwen3-30B-A3B show training throughput per GPU jumping from 3075 to 11340 tokens per second. The solution also enables the fine-tuning of very large models, such as the 550B parameter Nemotron 3 Ultra, which would exceed memory limits with the standard Transformers v5. Code and benchmarks are available on GitHub.

How to Detect AI-Generated Videos? A Review of Dynamic, Traceable, and Explainable Detection Systems

**How to Detect AI-Generated Videos: A Survey on Dynamic, Traceable, and Explainable Detection Systems** With rapid advances in AI video generation (e.g., Sora, Veo), creating highly realistic, multi-minute videos is now possible, widening the gap with detection research. Current AI video detection, often limited to unreliable binary classifications, is insufficient. This survey, accepted at ACL 2026, reframes the goal as **"factual fidelity verification"**—checking if a video's content (who, when, where, what) aligns with the real world perceptually and cognitively. It categorizes AI-generated videos into three paradigms: **Local Manipulation Videos (LMV**, e.g., face swaps), **Audio-Visual Editing (AVE**, e.g., lip-syncing), and **Generative Video Synthesis (GVS**, fully synthetic videos like Sora's). Detection challenges evolve from visual artifacts in LMV to multi-modal inconsistencies in AVE and higher-level world knowledge violations in GVS. The core proposal is a **Vision-Language Dual-View framework** with four hierarchical layers: 1. **Layer 1 (Intrinsic Visual Cues):** Analyzes low-level signal statistics, noise patterns, and physiological signals. 2. **Layer 2 (Spatiotemporal Consistency):** Checks for temporal coherence in object motion and scene dynamics. 3. **Layer 3 (Cross-Modal Consistency):** Verifies alignment between video, audio, and text within the video. 4. **Layer 4 (Language-Guided World-Level Reasoning):** Uses external knowledge, facts, and physical laws to judge semantic plausibility and factual correctness. The survey traces a shift in detection focus from lower layers (1 & 2) toward higher, language-involved layers (3 & 4). It also reviews evolving evaluation metrics and datasets tailored for each video paradigm. The conclusion advocates for a **dynamic, evidence-first detection system** that moves beyond simple classification. Future trustworthy detection requires combining visual evidence (from CV) with semantic reasoning and explanation (from NLP & multimodal AI), ultimately creating traceable and explainable judgments about a video's adherence to real-world constraints.

It Turns Out the First Real-World Application of AI x Crypto is in Security Auditing

The article explores the surprising trend where AI's first major impact on crypto has been in security auditing, not in areas like trading or analytics. It details how AI-powered tools are dramatically lowering the barrier to finding smart contract vulnerabilities, enabling attackers to scan thousands of contracts and execute exploits within minutes. This has rendered traditional, manually-produced audit reports with their month-long validity periods increasingly obsolete, creating a critical "structural crack" in the old security model. Cases like Drift Protocol and KelpDAO show that even extensively audited protocols can be hacked through social engineering, operational flaws, or infrastructure misconfigurations beyond pure code review. Attackers are also using AI to find and exploit vulnerabilities in years-old, deployed contracts. Notably, OpenZeppelin's co-founder has expressed a grim view that "all DeFi is insecure" due to AI's asymmetric advantage. In response, the audit industry is undergoing a fundamental shift. While there's a short-term spike in defensive re-audits, the long-term business model is changing. Firms are developing AI-assisted systems and moving from one-time report deliveries towards embedded, continuous services like real-time monitoring and formal verification. Examples include AI tools uncovering critical, previously missed vulnerabilities in heavily audited protocols like Curve Finance and Zcash. The conclusion is that security must become a continuous investment, not a one-time checkbox, and audit firms must rapidly evolve their tools and service models to survive.

Never expected that the first tangible application of AI x Crypto is in security auditing

Unexpectedly, the initial major application of AI in the Crypto sphere has turned out to be security auditing. In 2026, DeFi has faced significant security challenges, with 121 hacking incidents resulting in approximately $942 million in losses. While AI was expected to first impact areas like quantitative trading, its initial breakthrough has instead transformed security auditing by drastically lowering the cost and skill barrier for finding smart contract vulnerabilities. The traditional audit model is facing obsolescence. Advanced AI models, such as Claude Mythos, enable attackers to scan thousands of contracts and identify vulnerability patterns at scale, compressing the time from discovery to execution to mere minutes. This renders the month-long validity of traditional audit reports ineffective. Notably, attacks now frequently target well-audited, established protocols by exploiting business logic flaws, operational security weaknesses, and even years-old historical contracts, demonstrating that old audit reports offer zero protection. This pressure is forcing a fundamental shift in the industry. In the short term, a wave of defensive re-auditing is occurring, driven by projects seeking to meet new AI-era security standards and regulatory requirements. In the long run, audit firms' business models are diverging. The one-time report delivery model is declining in value, as evidenced by platforms like Code4rena shutting down. Leading firms are now pivoting towards AI-powered defense, integrating continuous monitoring, real-time on-chain risk detection, and embedding security directly into the development phase, as seen with tools like OpenZeppelin's Skills system. Ultimately, the era of "audit once, secure forever" is over. Security must become a continuous, embedded infrastructure investment for projects. For audit companies, survival depends on proactively transforming from traditional service providers into platforms offering AI-native, ongoing security solutions.

$3M Exploit Hits Polymarket: Users to Receive Full Refunds After Third-Party Breach

Polymarket will fully reimburse users affected by a front-end exploit that stole approximately $3 million in crypto assets. The company stated the incident was not a flaw in its core protocol but a supply chain attack. A compromised third-party vendor injected a malicious script into the platform's front-end for a limited number of users, allowing the attacker to drain funds from about 15 wallets while they interacted with the site. The stolen assets, primarily Polymarket's pUSD stablecoin, were bridged to Ethereum and converted to roughly 1,893 ETH. This marks the second security incident for Polymarket in under two months, following a separate $700,000 loss. The event highlights growing risks associated with third-party dependencies in the crypto industry.
