first_img Spanish police arrested a 16-year-old boy involved in operating the KillSec ransomware group

According to Decrypt, the European Union's law enforcement agency reported that Spanish police arrested a 16-year-old Romanian suspect in Alicante, suspected of being an administrator and main operator of the ransomware group KillSec.Two other suspects in their twenties were arrested in the UK and Romania, respectively; another developer who just turned 18 in August this year has been identified but has not been arrested due to some crimes occurring during their minor years.This operation, codenamed Operation KillSwitch, was led by the Hamburg State Criminal Police and the city's prosecution office, focusing on approximately 1,000 suspected attacks worldwide, with about 500 confirmed as successful intrusions.Law enforcement searched eight locations in Spain, Greece, Romania, and the UK, seized five central servers, and redirected related domain names to seizure announcement pages, while also confiscating at least 110 TB of stolen data.KillSec has been active since around 2024, exploiting software vulnerabilities and poorly secured cloud storage entry points to infiltrate corporate systems, copying internal data and naming victim organizations on dark web leak sites, threatening to publicly release documents to demand cryptocurrency ransoms, and if the target refuses to pay, they release the data for free.The Swiss Federal Police noted that the group also employed double extortion tactics, first encrypting servers and then applying pressure. U.S. prosecutors' charges indicate that a Dutch national residing in the UK, Fouad Eltibrizi (nicknamed Archduke), was indicted by a federal grand jury in Puerto Rico on September 16, subsequently arrested, and awaiting extradition, facing up to 10 years in prison. The European Cybercrime Centre, under the European Union Agency for Law Enforcement Cooperation, is assisting in tracing cryptocurrency funds and conducting digital forensics.

first_img XRP Ledger carries the Brazilian CSD BR fund records, involving approximately 4 trillion USD in assets

The regulated operator responsible for the registration, securities custody, and settlement system of the Brazilian financial market, CSD BR, has begun to record the ownership of shares in certain investment funds under BTG Pactual, mirroring them to the public XRP Ledger. CSD BR manages registered assets exceeding 22 trillion Brazilian Reais, approximately 4 trillion US dollars. Its existing database still serves as the official record for registration, custody, and settlement, and the relevant assets have not been transferred to the XRP Ledger; fund shares will be presented in token form on the XRPL.This blockchain copy aims to allow approved banks and institutions to verify ownership changes in real-time, replacing post-reconciliation, reducing the slow and costly verification process, while retaining identity checks and regulatory controls. Anyone can read the token circulation on the XRPL, but CSD BR still controls who has the right to hold and transfer these tokens. The tokens adopt the multi-purpose token standard of the XRP Ledger, allowing issuers to restrict participants and freeze assets or revoke transactions upon regulatory or court requests, while participants still need to pass identity and anti-money laundering checks.The project starts with real fund records, distinguishing it from previous pilots that used test assets or closed networks. CSD BR was established in 2018 and is authorized by the Central Bank of Brazil and the securities regulatory authority. After becoming familiar with the mirroring system, CSD BR and Ripple plan to test the direct issuance of assets on the XRP Ledger and allow approved participants to trade, with potential targets including Brazilian real estate receivables and agricultural receivables.
