Individuals and organizations in Brazil face a unique cyber threat landscape because it is a complex interplay of global and local threats, posing significant risks to individuals, organizations, and critical sectors of Brazilian society. Many of the cyber espionage threat actors that are prolific in campaigns across the globe are also active in carrying out attempted intrusions into critical sectors of Brazilian society. Brazil also faces threats posed by the worldwide increase in multifaceted extortion, as ransomware and data theft continue to rise. At the same time, the threat landscape in Brazil is shaped by a domestic cybercriminal market, where threat actors coordinate to carry out account takeovers, conduct carding and fraud, deploy banking malware and facilitate other cyber threats targeting Brazilians. The rise of the Global South, with Brazil at the forefront, marks a significant shift in the geopolitical landscape; one that extends into the cyber realm. As Brazil\'s influence grows, so does its digital footprint, making it an increasingly attractive target for cyber threats originating from both global and domestic actors. This blog post brings together Google\'s collective understanding of the Brazilian threat landscape, combining insights from Google\'s Threat Analysis Group (TAG) and Mandiant\'s frontline intelligence. As Brazil\'s economic and geopolitical role in global affairs continues to rise, threat actors from an array of motivations will further seek opportunities to exploit the digital infrastructure that Brazilians rely upon across all aspects of society. By sharing our global perspective, we hope to enable greater resiliency in mitigating these threats. Google uses the results of our research to improve the safety and security of our products, making them secure by default. Chrome OS has built-in and proactive security to protect from ransomware, and there have been no reported ransomware attacks ever on any business, education, or consumer Chrome OS device. Google security teams continuously monitor for new threat activity, and all identified websites and domains are added to Safe Browsing to protect users from further exploitation. We deploy and constantly update Android detections to protect users\' devices and prevent malicious actors from publishing malware to the Google Play Store. We send targeted Gmail and Workspace users government-backed attacker alerts, notifying them of the activity and encouraging potential targets to enable Enhanced Safe Browsing for Chrome and ensure that all devices are updated.

Written by: Kelli Vanderlee, Jamie Collier
Executive Summary The election cybersecurity landscape globally is characterized by a diversity of targets, tactics, and threats. Elections attract threat activity from a variety of threat actors including: state-sponsored actors, cyber criminals, hacktivists, insiders, and information operations as-a-service entities. Mandiant assesses with high confidence that state-sponsored actors pose the most serious cybersecurity risk to elections. Operations targeting election-related infrastructure can combine cyber intrusion activity, disruptive and destructive capabilities, and information operations, which include elements of public-facing advertisement and amplification of threat activity claims. Successful targeting does not automatically translate to high impact. Many threat actors have struggled to influence or achieve significant effects, despite their best efforts. When we look across the globe we find that the attack surface of an election involves a wide variety of entities beyond voting machines and voter registries. In fact, our observations of past cycles indicate that cyber operations target the major players involved in campaigning, political parties, news and social media more frequently than actual election infrastructure. Securing elections requires a comprehensive understanding of many types of threats and tactics, from distributed denial of service (DDoS) to data theft to deepfakes, that are likely to impact elections in 2024. It is vital to understand the variety of relevant threat vectors and how they relate, and to ensure mitigation strategies are in place to address the full scope of potential activity. Election organizations should consider steps to harden infrastructure against common attacks, and utilize account security tools such as Google\'s Advanced Protection Program to protect high-risk accounts. Introduction The 2024 global election cybersecurity landscape is characterized by a diversity of targets, tactics, and threats. An expansive ecosystem of systems, administrators, campaign infrastructure, and public communications venues must be secured against a diverse array of operators and methods. Any election cybersecurity strategy should begin with a survey of the threat landscape to build a more proactive and tailored security posture. The cybersecurity community must keep pace as more than two billion voters are expected to head to the polls in 2024. With elections in more than an estimated 50 countries, there is an opportunity to dynamically track how threats to democracy evolve. Understanding how threats are targeting one country will enable us to better anticipate and prepare for upcoming elections globally. At the same time, we must also appreciate the unique context of different countries. Election threats to South Africa, India, and the United States will inevitably differ in some regard. In either case, there is an opportunity for us to prepare with the advantage of intelligence. |

While not as common as Windows malware, there has been a steady stream of malware discovered over the years that runs on the OS X operating system, now rebranded as macOS. February saw three particularly interesting publications on the topic of macOS malware: a Trojan Cocoa application that sends system information including keychain data back to the attacker, a macOS version of APT28\'s Xagent malware, and a new Trojan ransomware. In this blog, the FLARE team would like to introduce two small tools that can aid in the task of reverse engineering Cocoa applications for macOS. In order to |

Le rôle des acteurs de l'État-nation dans les cyberattaques a peut-être été le plus largement révélé en février 2013 lorsque mandiant href = "https://www.mandiant.com/resources/mandiant-expose-apt1-chinas-cyber-espionage-units" cible = "_ Blank"> Rapport APT1, en Chine.Aujourd'hui, nous publions un nouveau rapport: apt28:Une fenêtre sur les opérations de cyber-espionnage de la Russie?
Ce rapport se concentre sur un groupe de menaces que nous avons désigné comme APT28.Alors que les logiciels malveillants d'APT28 \\ sont assez connus dans la communauté de la cybersécurité, notre rapport détaille des informations supplémentaires exposant des opérations en cours et ciblées qui, selon nous, indiquent un sponsor gouvernemental basé à Moscou.

The role of nation-state actors in cyber attacks was perhaps most widely revealed in February 2013 when Mandiant released the APT1 report, which detailed a professional cyber espionage group based in China. Today we release a new report: APT28: A Window Into Russia\'s Cyber Espionage Operations? This report focuses on a threat group that we have designated as APT28. While APT28\'s malware is fairly well known in the cybersecurity community, our report details additional information exposing ongoing, focused operations that we believe indicate a government sponsor based in Moscow.
