por

PoR (Proof of Reserves) is a verification mechanism used by cryptocurrency exchanges or financial institutions to prove the amount of asset reserves they hold. Through PoR, institutions can demonstrate the transparency and security of their assets to users and regulators, typically achieved through third-party audits or cryptographic proofs. The implementation of PoR helps to enhance user trust in the platform and prevent financial risks caused by insufficient assets.

first_img Indian cybersecurity agency: AI agents unauthorizedly read corporate confidential records

The Indian Computer Emergency Response Team (CERT-In) released an important announcement this week titled "AI Agents as Attack Vectors," indicating that AI agents operated by unnamed model providers exceeded their granted task scope during testing, reading confidential business records in the online systems of Indian agencies, and no affected agencies discovered this behavior on their own.CERT-In stated that it received voluntary disclosures from several AI model providers, which indicated that these models accessed the online systems of Indian agencies while being researched and evaluated on the internet. The announcement did not disclose the names of the providers, models, or affected agencies. The agents read business records containing personal data and confidential materials, utilizing credentials and connection settings exposed in application configurations, public code repositories, and overly permissive cloud service roles. In some cases, the same credentials were recovered multiple times and reused in different operations.Additionally, CERT-In observed that criminals exploited publicly available AI-driven offensive security frameworks to scan for vulnerabilities, implement exploits, and launch economically motivated attacks against Indian entities, reducing the time from initial access to final impact from several days to just hours; these tools were repeatedly repackaged and deployed, with related deployments appearing on servers in multiple countries.

first_img Report: The cost of remittances using stablecoins is 84% lower than traditional transfers, with settlement taking just a few minutes

The third-quarter report released by the stablecoin payment network Borderless.xyz shows that the median cost of sending a $200 remittance through stablecoin funding channels is 1%, or $2; whereas, according to World Bank data, the median cost of traditional remittance channels is 6.36%, or $12.72. In comparison, the cost of stablecoin remittances is approximately 84% lower. This comparison uses Borderless's pricing for the third quarter of 2026 and World Bank data for the same period in 2025.In emerging markets, the cost advantage is also evident. The cost of stablecoin remittances in Sub-Saharan Africa is 2.9%, while traditional transfers are 8.46%; in Latin America, the figures are 1.25% and 5.64%, respectively. In terms of corporate payments, a $10,000 stablecoin transfer to the Eurozone can cost as low as $26 when choosing the lowest-cost service provider, with the median service provider costing $52; traditional international bank wire transfers for the same amount require $135 to $150, including transfer fees and a 1% foreign exchange spread.Regarding settlement speed, the report states that stablecoin payments can reach the recipient's local bank account within minutes. The median settlement time for Brazil's PIX network in the third quarter is 2 minutes, Mexico's SPEI is 3 minutes, and Colombia's PSE is 2 minutes; traditional SWIFT transfers typically settle the next day, with the slowest 10% taking 3 business days. The success rate for receiving funds varies significantly: Mexico's SPEI is 98.6%, Brazil's PIX is 97.8%, Colombia's PSE is 79%, and Costa Rica's SINPE is only 73%. Standard Chartered Bank recently pointed out that although the total market capitalization of stablecoins has grown relatively slowly this year, transaction volumes are still rising, and it is expected that this market will reach $2 trillion by 2030, two years later than previously predicted.

first_img NEAR Intents released a post-mortem report, revealing that the $3.8 million vulnerability originated from a deposit notification flaw

The cross-chain exchange protocol NEAR Intents released a post-mortem report attributing a $3.8 million vulnerability to a flaw in the deposit notification feature. The protocol deploys a public settlement contract on NEAR that maintains an internal ledger of deposited tokens, while withdrawals transfer tokens out via a cross-chain bridge. The report was published by NEAR Intents General Manager Alex Shevchenko on October 16, stating that the attacker withdrew $3.8 million before the protocol was shut down on October 1 and returned all funds within 36 hours of detection, with all affected users fully compensated.The report indicates that the feature notifies third-party contracts when tokens are deposited. The attacker created a contract that intentionally caused the notification to fail, allowing the token contract to refund the deposit while NEAR Intents retained the corresponding ledger credit. Through 23 failed deposit transactions, the attacker accumulated $3.8 million in unsupported balance, referred to in the report as ghost funds, and subsequently withdrew real tokens based on this and transferred them to other chains via the Omni infrastructure. Shevchenko stated that this was a vulnerability in the NEAR Intents contract, not in the Omni infrastructure.Withdrawals occurred between September 29 and October 1. The settlement contract was paused and reopened on October 1, with affected routes gradually restored, and contract-side deposits resumed on October 2. The report noted that the vulnerability went undetected because monitoring only compared the original chain assets with the total balance of NEAR side tokens, without comparing the total internal user balances with the actual tokens held by the contract; the team has since added this check and will automatically pause the contract when there is a balance inconsistency. The fix for the October vulnerability was deployed on October 2, but another serious vulnerability report regarding the same feature prompted its complete removal on October 7, with the relevant researcher receiving a $300,000 reward.

CryptoQuant: The proportion of new Bitcoin whales in the realized market value has risen to about 1/3, with a cost basis of approximately $77,000

CryptoQuant analyst MorenoDV_ published an analysis indicating that the realized market cap of new whales in Bitcoin is $78.61 billion, while old whales stand at $159.15 billion. New whales account for 33.06%, compared to about 18% earlier in 2026.Since September, the realized market cap of new whales has continued to grow, while old whales have remained relatively stable, with the growth primarily coming from new whales. The realized market cap is calculated based on the price at the last on-chain transfer of the tokens and does not represent the proportion of BTC supply.In terms of cost, the overall cost basis of new whales has decreased from a previous high of around $110,000 to about $68,000 at the end of August, before rebounding to around $77,000. The current BTC price is $82,134, which is approximately 6.7% higher than the cost basis of new whales.The analysis suggests that the data shows large holders buying during the downturn and continuing to accumulate as prices rebound. However, the turnover of the holder group and transfers between addresses can also inflate the realized market cap, so the growth in realized market cap cannot be interpreted as an equivalent influx of new funds. If BTC continues to fall below around $77,000, new whales will incur losses again, increasing the likelihood of selling during a rebound. The inflow to exchanges and realized losses can be used to determine whether this is short-term pressure or if large holders are starting to sell off again.
