Internal network of Brazil’s Ministry of Economy hit by ransomware attack

Recently, the Brazilian Ministry of Economy issued a statement saying that the internal network of the Treasury Secretariat was attacked by ransomware. The statement reads as follows:

A ransomware attack targeting the internal network of the Treasury Secretariat was discovered on Friday night (13th);

Containment measures have been taken immediately and federal police have been called;

Currently, security experts from the Secretariat of the National Ministry of Finance and the Digital Government Secretariat (DGS) are evaluating the impact of the attack;

In the first phase, the assessment concluded that the action had not compromised the Treasury Secretariat’s structural systems, such as the Integrated Financial Management System (SIAFI) and systems related to public debt, and safeguards were being implemented.

It is understood that the DGS operates under the Special Secretariat for the Management and Digital Government of the Ministry of Economy and plays a strategic role in the deployment of the Brazilian network. DGS is also the central agency for SISP, the system used to plan, coordinate, organize, operate, control and monitor the information technology resources of more than 200 federal government agencies.

Initial assessments to date have reportedly found no damage to the treasury’s structural systems, such as platforms related to public debt management. The Brazilian Ministry of Economy noted that new information on the incident will be disclosed in a timely manner and with appropriate transparency.

A separate statement issued by the Ministry of Finance and the Brazilian stock exchange on the 16th stated that the attack would not affect the operation of the Tesouro Direto project, which sells Brazilian government bonds to individuals.

Before Brazil’s Ministry of Finance, Brazil’s high electoral court suffered a major cyber attack in November 2020. The attack halted the court’s systems for more than two weeks. In terms of its sophistication and scope of damage, the incident was considered at the time the most comprehensive attack ever orchestrated against a Brazilian public sector agency; in Brazil’s private sector, major ransomware attacks this year have involved large companies , such as medical company Fleury and aerospace group Embraer.
