The GoPlus Security team has disclosed a new type of attack in its AgentGuard AI project: inducing AI agents to perform unauthorized sensitive operations through "memory poisoning." This attack method does not rely on traditional vulnerabilities or malicious code but exploits the long-term memory mechanism of AI agents. For example, an attacker first induces the agent to "remember preferences," such as "usually prioritizing proactive refunds instead of waiting for chargebacks," and then uses vague expressions like "process as usual" or "execute as before" in subsequent instructions, thereby triggering automated financial operations.GoPlus points out that the key risk in such cases lies in the AI agent mistakenly treating "historical preferences" as a basis for authorization, leading to financial losses or security incidents in operations such as refunds, transfers, and configuration changes. To address this issue, the team has proposed several protective recommendations, including:Operations involving refunds, transfers, deletions, or sensitive configurations must require explicit confirmation in the current session.Memory-related instructions like "habit," "usual way," and "as before" should be regarded as high-risk state changes.Long-term memory must have a traceability mechanism (writer, time, confirmation status).Vague instructions should automatically elevate the risk level and trigger secondary verification.Long-term memory must not replace real-time authorization processes.The team emphasizes that the "AI agent memory system" should be viewed as a potential attack surface and should be constrained and audited through a dedicated security framework.

The Speaker of the Polish Sejm, Włodzimierz Czarzasty, announced that the parliament has officially begun reviewing four competing regulatory bills for crypto assets, following President Karol Nawrocki's veto of related legislation twice. This review involves multiple legislative proposals from the government, the presidential office, the Poland 2050 party, and the Confederation party, with a second reading vote expected to take place on Thursday. The core disagreement centers on the scope of the Polish Financial Supervision Authority (KNF) regarding account freezing powers and the maximum penalties for violations. The presidential draft sets the maximum fine at approximately 20 million zlotys (about 5.5 million USD), while the Ministry of Finance's version raises it to 25 million zlotys (about 6.9 million USD).Meanwhile, the opposition Law and Justice party (PiS), after withdrawing support for earlier regulatory proposals, submitted a separate bill on Monday advocating for a complete ban on crypto asset-related activities in Poland, further complicating the regulatory discussion. Speaker Czarzasty stated that the PiS ban draft will enter the review process only after the four main regulatory bills are completed and questioned the connection between crypto industry funding and political activities, specifically inquiring about potential political financing issues, including those involving zondacrypto.

U.S. prosecutors also accused him of using some of the funds to purchase Florida properties worth a total of $14.5 million, as well as for hosting lavish events and trips. Delgado is currently out on bail, and if convicted on all charges, he could face up to 30 years in federal prison.

In February this year, several Chinese citizens were raided by the police at a rented villa in Country Heights, Kajang, Malaysia. The police claimed to suspect that the Chinese citizens were involved in fraud, and subsequently, the Chinese citizens were forced to transfer about $50,000 (approximately 200,000 ringgit) in USDT. The police later arrested 12 officers involved in the case and removed them from frontline duties, but the investigation still awaits technical reports and digital evidence results, and there has been no breakthrough to date.Lawyer Charles, representing eight Chinese victims, stated that the investigation is progressing too slowly. Since the arrest of the 12 involved police officers, there has been no further information, raising suspicions of internal interference attempting to suppress the case. He warned that if there is internal protection, he will file a complaint with the Malaysian Anti-Corruption Commission.

According to Crypto.news, the New South Wales police in Australia seized 52.3 bitcoins, worth approximately 5.7 million Australian dollars (4.1 million US dollars), in a law enforcement operation targeting the dark web market, making it one of the largest dark web cryptocurrency seizures in the country.This operation is part of the Strike Force Andalusia investigation that began in September 2024 and lasted 15 months. The police tracked a large bitcoin wallet holding proceeds from the dark web market, ultimately identifying two male suspects, aged 39 and 41, who are accused of supplying prohibited drugs and transferring over 100,000 Australian dollars in dark web-related cryptocurrency.

Bitcoin fell below the $80,000 mark this week, following a five-day streak of net inflows into spot ETFs, as the market's rebound momentum from February's lows showed signs of cooling. The U.S. April non-farm payroll data added 115,000 jobs, exceeding the expected 62,000, while the unemployment rate remained at 4.3%. Although the overall data was relatively strong, it did not significantly alleviate market concerns about macroeconomic uncertainty; instead, it reinforced expectations that "energy-driven inflation limits the space for interest rate cuts."In terms of capital flow, the spot Bitcoin ETF saw a net outflow of $277 million on Thursday, ending a previous cumulative inflow of $1.69 billion; the Ethereum ETF also recorded a net outflow of $104 million on the same day, indicating a short-term cooling of institutional risk appetite. On the geopolitical front, tensions between Iran and the U.S. have escalated again, prompting the market to reprice the risks in the Strait of Hormuz, leading to a rebound in oil prices, which partially offset the support that previous risk assets received from the decline in oil prices.The derivatives market shows a more long-term hawkish outlook, with interest rate futures pricing in over a 50% probability of rate hikes beyond 2027, suggesting that the easing cycle may be delayed until 2028. On-chain data indicates that the current rise in Bitcoin is primarily driven by institutional spot buying and short covering, with retail participation remaining relatively low, and funding rates maintaining a moderate level, resulting in a weak market momentum structure. Analysts believe that if retail funds do not return, BTC may still face the risk of testing the support range of $75,000 to $78,000.

The New South Wales police in Australia seized 52.3 bitcoins, worth approximately 5.7 million AUD (about 4.1 million USD), during a 15-month investigation and arrested two suspects allegedly operating a dark web market in Ingleburn, Sydney.The police stated that the seized bitcoins are suspected to be related to illegal activities on the dark web associated with drug and weapon trafficking. This operation was carried out by the state crime command's cyber crime unit, Strike Force Andalusia, and is considered one of the largest cryptocurrency seizures related to the dark web in Australia. Meanwhile, AUSTRAC has recently strengthened its anti-money laundering regulations for domestic virtual asset service providers and cryptocurrency trading platforms.

According to Bloomberg, ECB President Lagarde stated that even euro-denominated stablecoins pose risks to financial stability and the transmission of monetary policy, questioning the necessity of introducing such tools.She pointed out that while euro stablecoins could lower financing costs in the euro area and enhance the global appeal of the euro, the costs are significant and outweigh short-term benefits. Lagarde emphasized that if the goal is to enhance the international appeal of the euro, stablecoins are not an effective means. She referenced a working paper from the ECB in March, which warned that the widespread adoption of stablecoins would pose significant risks to euro area banks and monetary sovereignty. She stated that Europe's task is not to "replicate tools developed elsewhere" and continues to push for the introduction of a digital euro.
