Mercado Bitcoin identifies and contains security incident, with possible loss of R$ 217 million

Mercado Bitcoin, one of the main digital asset exchanges in Brazil, announced on Monday, November 2nd, that it detected and managed to contain a security incident in one of its systems. As a preventive measure, the company temporarily suspended deposit and withdrawal services.

The alert regarding possible unusual transactions was issued by Hypernative, a company specializing in blockchain security. According to monitoring conducted by this company, approximately US$ 40 million, which is equivalent to about R$ 217.7 million, were transferred from wallets linked to the exchange.

In its official statement, Mercado Bitcoin assured that the incident was quickly identified and contained, emphasizing that there was no damage to clients or data leakage. As a protective measure, deposits and withdrawals were temporarily halted. The company's teams are actively involved in the investigation, tracking the assets, and coordinating necessary actions with competent authorities, promising periodic updates.

Most of these transfers occurred between 3:19 AM and 3:53 AM on the day in question, following Brasília time zone. The assets were directed to recently created addresses that were identified by the security company as belonging to a probable intruder.

Although Mercado Bitcoin confirmed the containment of the problem without affecting clients or exposing data, it did not endorse the value estimated by Hypernative, keeping the case under investigation with the relevant bodies.

This event occurs just a few days after Binance reported what was classified as the largest cryptocurrency theft in history. On Friday, October 30th, the major market exchange announced that a hack resulted in the movement of about US$ 6.3 billion (R$ 33.9 billion) in user wallet assets.

Binance's preliminary analysis suggests that the criminals may have gained access to the notebook of a DevOps engineer, a professional responsible for integration between development and operations. Using this computer, the hackers allegedly managed to penetrate internal exchange services by exploiting the employee's access privileges. Binance guaranteed that it would fully cover all damages caused by the attack and, at the time, also suspended deposits and withdrawals during the incident analysis, although these services have since been restored.

Vivo evaluates acquisition of Vero to strengthen fiber optic operations

Telefônica Brasil, the controlling company of Vivo, is reportedly analyzing the possibility of acquiring the provider Vero. According to information gathered by Estadão, consultants have already been hired and negotiations are underway, although no agreement has been formalized yet.

If the transaction materializes, it would significantly strengthen Vivo's presence in the fiber optic segment and expand its customer base. Additionally, Vero would bring a virtual mobile telephony operation to the company, serving both consumers and as structural support for other brands.

Vero's main value lies in its broadband base. Data provided by Anatel indicates that Vero has approximately 1.29 million fixed internet accesses, ranking sixth in the Brazilian market. Vivo, on the other hand, is in second place, with about 8.54 million accesses, trailing only Claro.

Vero provides services in hundreds of municipalities located in states such as Minas Gerais, São Paulo, Paraná, Santa Catarina, and Rio Grande do Sul. A potential acquisition also aligns with the scenario of consolidation among various providers, large and medium. Recently, Giga+ stated that it is in talks with Sky regarding a possible business merger.

Beyond fixed internet, Vero operates as a Mobile Virtual Network Operator (MVNO), utilizing TIM's network. In June, the company had about 340,000 mobile users, which already accounted for 7% of its revenue. Furthermore, it offers infrastructure for other companies to provide cell phone plans under their own brands.

Among the accredited companies are Veek, Salvy, Ampernet, and regional providers. This deal could be of interest to Vivo by providing a ready structure to serve smaller brands, although the exact role of this structure in a potential purchase has not yet been defined.

The possible sale occurs amid financial difficulties for Vero, which has a net debt close to R$ 3 billion and recorded a reduction in its subscriber base this year. Concurrently, Vivo has been investing in reinforcing its fiber infrastructure. In May, Vivo assumed full control of FiBrasil, a company created specifically to manage fiber optic networks. The incorporation of Vero would expand Vivo's presence in the broadband retail sector and add virtual mobile operation capacity.

As of now, there is no signed contract nor any guarantee that the deal will be finalized. Until the companies release an official decision, there are no confirmed changes for customers.

France confirms first case of Shamond virus in human; patient died

French health authorities reported the first detection of the Shamond virus in a human, but the patient has died.

At the same time, French authorities emphasized that there is currently no threat to the general population.

The Shamond virus is an orthobunyavirus transmitted by insects and primarily affects cattle, especially bulls, being carried by biting mosquitoes.

Previously, the Order of Veterinary Doctors confirmed the presence of the Shamond virus (SHAV) in Portugal last week.

SHAV belongs to the genus Orthobunyavirus and serogroup Simbu. It is primarily transmitted by bites of small insects of the genus Culicoides (vectors), and cattle are particularly susceptible to infection with this virus. Symptoms in animals can include fever, diarrhea, exhaustion, and reduced milk yield, according to the statement.

In pregnant females, the infection can also be associated with abortions and fetal developmental defects.

According to the report, sheep and goats can also become infected, usually without obvious clinical signs.

Nevertheless, the Order of Doctors notes that 'there is no evidence that the Shamond virus is zoonotic, and the risk of transmission to humans is unknown.'

Two shipments of graphics cards worth 2.5 million reais disappear at Guarulhos Airport

Two shipments of GeForce RTX 5090 graphics cards delivered to Brazil disappeared last weekend at Guarulhos Airport (GRU) in São Paulo. This incident was reported by the official account of Grupo Oderço, which imports these graphics cards.

According to the distributor's statement, the two lost pallets represent damages amounting to 2.5 million reais, which presumably includes hundreds of graphics chips. The publication also notes that there are no video recordings of the component theft. The company is demanding an explanation from the managing company of GRU Airport, responsible for operations at São Paulo International Airport.

The missing models are products of the Zotac brand. On the national online store, this version is available for a price starting from 35 thousand reais. In response to G1's inquiry, GRU Airport assured that it is 'making every effort' to resolve the issue and that the fact of the graphics card disappearance 'has been reported to competent authorities.'

According to the concessionaire, Grupo Oderço has already received instructions regarding the procedure for receiving compensation for this situation. RTX 5090 graphics cards are considered a luxury item for those who want to build a gaming PC or a computer capable of performing heavy tasks, such as software editing.

Each stolen unit is valued at approximately 35 thousand reais on the Brazilian market, but Oderço reports damages of 2.5 million reais based on the cost price. Models of this type gain value in the market due to the memory chip crisis.

Each Zotac RTX 5090 is equipped with at least 32 GB of GDDR7 RAM, which is the most modern market standard. Furthermore, the version features three cooling fans, RGB lighting, and other characteristics that surpass standard Nvidia components.

The GRU Airport concessionaire stated that the disappearance occurred last Thursday (10/04), when Grupo Oderço was informed about the compensation procedure. In its statement, the airport administrator also emphasized that the distributor must provide the requested documentation to complete the process. It should be noted that the company filed a complaint on Saturday (10/06), demanding clarification and the recovery of the cargo. As of now, there is no information on the resolution of the case.
