2025-04-17 10:31:17 | Autour du monde en 90 jours: les acteurs parrainés par l'État essaient Clickfix Around the World in 90 Days: State-Sponsored Actors Try ClickFix (lien direct) |
Conclusions clés Alors que principalement une technique affiliée à des acteurs cybercrimins, les chercheurs de ProofPoint ont découvert des acteurs parrainés par l'État dans plusieurs campagnes en utilisant la technique d'ingénierie sociale ClickFix pour la première fois. Sur seulement une période de trois mois de la fin de 2024 au début de 2025, des groupes de Corée du Nord, d'Iran et de Russie ont tous été vus en utilisant la technique Clickfix dans leur activité de routine. L'incorporation de ClickFix ne révolutionne pas les campagnes réalisées par TA427, TA450, UNK_Remooterogue et TA422 mais remplace plutôt les étapes d'installation et d'exécution dans les chaînes d'infection existantes. Bien que actuellement limité à quelques groupes parrainés par l'État, la popularité croissante du fixe de clics dans la cybercriminalité au cours de la dernière année ainsi que dans les campagnes d'espionnage au cours des derniers mois suggère que la technique sera probablement plus testée ou adoptée par des acteurs parrainés par l'État. Aperçu Une tendance majeure dans le paysage des menaces est la fluidité des tactiques, des techniques et des procédures (TTPS). Les acteurs de menace partagent, copiernt, voler, adopter et tester les TTP de la métier exposée publiquement ou l'interaction avec d'autres groupes de menaces. Plus précisément, les acteurs parrainés par l'État ont souvent mis à profit les techniques développées et déployées pour la première fois par des acteurs cybercriminaux. Par exemple, les acteurs de la menace nord-coréenne copiant les techniques de la cybercriminalité pour voler la crypto-monnaie au nom du gouvernement, ou des groupes chinois imitant les chaînes d'infection de cybercriminalité pour livrer des logiciels malveillants dans les opérations d'espionnage. L'exemple le plus récent de cette tendance est Clickfix. ClickFix est une technique d'ingénierie sociale qui utilise des boîtes de dialogue avec des instructions pour copier, coller et exécuter des commandes malveillantes sur la machine Target \\. Cette technique créative utilise non seulement de faux messages d'erreur comme problème, mais aussi une alerte faisant autorité et des instructions provenant du système d'exploitation en tant que solution. Principalement observé dans l'activité de la cybercriminalité, la technique Clickfix a été vue pour la première fois début mars 2024 déployé par le courtier d'accès initial TA571 et le cluster Clearfake, après quoi il a inondé le paysage des menaces. Un an plus tard, au moins quatre acteurs de menaces parrainés par l'État ont depuis expérimenté des variations de cette technique dans le cadre de leurs campagnes d'espionnage habituées. Sur environ trois mois d'octobre 2024 à janvier 2025, les acteurs de la menace provenant de trois pays distincts (Corée du Nord, Iran et Russie) ont incorporé Clickfix comme étape de leurs chaînes d'infection. Corée du Nord: TA427 En janvier et février 2025, ProofPoint a d'abord observé les opérateurs TA427 ciblant les individus dans moins de cinq organisations dans le secteur des ateliers avec une nouvelle chaîne d'infection en utilisant la technique ClickFix. Ta427 chevauche avec des tiers de l'activité appelée kimsuky ou grésil émeraude. TA427 a établi un contact initial avec l'objectif grâce à une demande de réunion d'un expéditeur usurpé livré aux cibles traditionnelles TA427 travaillant sur les affaires nord-coréennes. Après une brève conversation pour engager la cible et renforcer la confiance, comme on le voit souvent dans l'activité TA427, les attaquants ont dirigé la cible vers un site contrôlé par l'attaquant où ils ont convaincu la cible d'exécuter une commande PowerShell. Bien qu'une chaîne n'ait pas réussi à récupérer d'autres charges utiles, une autre instance de cette campagne comprenait une chaîne à plusieurs étages qui a exécuté PowerShell, VBS et les scripts par lots, ce qui a finalement conduit à une charge utile finale - Quasarrat | Malware Tool Vulnerability Threat Prediction Cloud | APT 28 | ★★★ |

Written by: Aurora Blum, Kelli Vanderlee
Like many countries across the globe, Mexico faces a cyber threat landscape made up of a complex interplay of global and local threats, with threat actors carrying out attempted intrusions into critical sectors of Mexican society. Mexico also faces threats posed by the worldwide increase in multifaceted extortion, as ransomware and data theft continue to rise. Threat actors with an array of motivations continue to seek opportunities to exploit the digital infrastructure that Mexicans rely on across all aspects of society. This joint blog brings together our collective understanding of the cyber threat landscape impacting Mexico, combining insights from Google\'s Threat Analysis Group (TAG) and Mandiant\'s frontline intelligence. By sharing our global perspective, especially during today\'s Google for Mexico event, we hope to enable greater resiliency in mitigating these threats. Cyber Espionage Operations Targeting Mexico As the 12th largest economy in the world, Mexico draws attention from cyber espionage actors from multiple nations, with targeting patterns mirroring broader priorities and focus areas that we see elsewhere. Since 2020, cyber espionage groups from more than 10 countries have targeted users in Mexico; however, more than 77% of government-backed phishing activity is concentrated among groups from the People\'s Republic of China (PRC), North Korea, and Russia. 
Figure 1: Government-backed phishing activity targeting Mexico, January 2020 – August 2024
The examples here highlight recent and historical examples where cyber espionage actors have targeted users and organizations in Mexico. It should be noted that these campaigns describe targeting and do not indicate successful compromise or exploitation.
PRC Cyber Espionage Activity Targeting Mexico
Since 2020, we have observed activity from seven cyber espionage groups with links to the PRC targeting users in Mexico, accounting for a third of government-backed phishing activity in the country.
This volume of PRC cyber espionage is similar to activity in other regions where Chinese government investment has been focused, such as countries within China\'s Belt and Road Initiative. In addition to activity targeting Gmail users, PRC-backed groups have targeted Mexican government agencies, higher |

Written by: John Hultquist
As North Atlantic Treaty Organization (NATO) members and partners gather for a historic summit, it is important to take stock of one of its most pressing challenges-the cyber threat. The Alliance faces a barrage of malicious cyber activity from all over the globe, carried out by emboldened state-sponsored actors, hacktivists, and criminals who are willing to cross lines and carry out activity that was previously considered unlikely or inconceivable. In addition to military targets, NATO must consider the risks that hybrid threats like malicious cyber activity pose to hospitals, civil society, and other targets, which could impact resilience in a contingency. The war in Ukraine is undoubtedly linked to escalating cyber threat activity, but many of these threats will continue to grow separately and in parallel. NATO must contend with covert, aggressive malicious cyber actors that are seeking to gather intelligence, preparing to or currently attacking critical infrastructure, and working to undermine the Alliance with elaborate disinformation schemes. In order to protect its customers and clients, Google is closely tracking cyber threats, including those highlighted in this report; however, this is just a glimpse at a much larger and evolving landscape. Cyber Espionage NATO\'s adversaries have long sought to leverage cyber espionage to develop insight into the political, diplomatic, and military disposition of the Alliance and to steal its defense technologies and economic secrets. However, intelligence on the Alliance in the coming months will be of heightened importance. This year\'s summit is a transition period, with the appointment of Mark Rutte as the new Secretary General and a number of adaptations expected to be rolled out to shore up the Alliance\'s defense posture and its long-term support for Ukraine. Successful cyber espionage from threat actors could potentially undermine the Alliance\'s strategic advantage and inform adversary leadership on how to anticipate and counteract NATO\'s initiatives and investments. NATO is targeted by cyber espionage activity from actors around the world with varying capabilities. Many still rely on technically simple but operationally effective methods, like social engineering. Others have evolved and elevated their tradecraft to levels that distinguish themselves as formidable adversaries for even the most experienced defenders. APT29 (ICECAP) Publicly attributed to the Russian Foreign Intelligence Services (SVR) by several governments, APT29 is heavily focused on diplomatic and political intelligence collection, principally targeting Europe and NATO member states. APT29 has been involved in multiple high-profile breaches of technology firms that were designed to provide access to the public sector. In the past year, Mandiant has observed APT29 targeting technology companies and IT service providers in NATO member countries to facilitate third-party and software supply chain compromises of government and poli |

Written by: Kristen Dennesen, Luke McNamara, Dmitrij Lenz, Adam Weidemann, Aline Bueno
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.

2024-04-25 10:00:00 | Pole Voûte: cyber-menaces aux élections mondiales Poll Vaulting: Cyber Threats to Global Elections (lien direct) |
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. |

The content of this post is solely the responsibility of the author. AT&T does not adopt or endorse any of the views, positions, or information provided by the author in this article. The supply chain, already fragile in the USA, is at severe and significant risk of damage by cyberattacks. According to research analyzed by Forbes, supply chain attacks now account for a huge 62% of all commercial attacks, a clear indication of the scale of the challenge faced by the supply chain and the logistics industry as a whole. There are solutions out there, however, and the most simple of these concerns a simple upskilling of supply chain professionals to be aware of cybersecurity systems and threats. In an industry dominated by the need for trust, this is something that perhaps can come naturally for the supply chain. Building trust and awareness At the heart of a successful supply chain relationship is trust between partners. Building that trust, and securing high quality business partners, relies on a few factors. Cybersecurity experts and responsible officers will see some familiarity - due diligence, scrutiny over figures, and continuous monitoring. In simple terms, an effective framework of checking and rechecking work, monitored for compliance on all sides. These factors are a key part of new federal cybersecurity rules, according to news agency Reuters. Among other measures are a requirement for companies to have rigorous control over system patching, and measures that would require cloud hosted services to identify foreign customers. These are simple but important steps, and give a hint to supply chain businesses as to what they should be doing; putting in measures to monitor, control, and enact compliance on cybersecurity threats. That being said, it can be the case that the software isn’t in place within individual businesses to ensure that level of control. The right tools, and the right personnel, is also essential. The importance of software Back in April, the UK’s National Cyber Security Centre released details of specific threats made by Russian actors against business infrastructure in the USA and UK. Highlighted in this were specific weaknesses in business systems, and that includes in hardware and software used by millions of businesses worldwide. The message is simple - even industry standard software and devices have their problems, and businesses have to keep track of that. There are two arms to ensure this is completed. Firstly, the business should have a cybersecurity officer in place whose role it is to monitor current measures and ensure they are kept up to date. Secondly, budget and time must be allocated at an executive level firstly to promote networking between the business and cybersecurity firms, and between partner businesses to ensure that even cybersecurity measures are implemented across the chain. Utilizing AI There is something of a digital arms race when it comes to artificial intelligence. As ZDNet notes, the lack of clear regulation is providing a lot of leeway for malicious actors to innovate, but for businesses to act, too. While regulations are now coming in, it remains that there is a clear role for AI in prevention. According t | Threat Cloud | APT 28 ChatGPT | ★★ |

2022-08-18 08:00:00 | Ukraine and the fragility of agriculture security (lien direct) |  By Joe Marshall.The war in Ukraine has had far-reaching global implications and one of the most immediate effects felt will be on the global supply chain for food. This war-induced fragility has exposed the weaknesses of how we feed ourselves globally. Ransomware cartels and other adversaries are well aware of this and are actively exploiting that fragility. For the past six years, Cisco Talos has been actively involved in assisting public and private institutions in Ukraine to defend themselves against state-sponsored actors. Our involvement stretches the gamut from commercial to critical infrastructure, to election security. Our presence has afforded us unique opportunities and observations about cybersecurity in a macro and micro way. Ukraine has been a frequent victim of state-sponsored cyber attacks aimed at critical infrastructures like power and transportation. Talos is proud to stand with our partners in Ukraine and help defend their critical networks and help users there maintain access to necessary services. Now that Russia has invaded Ukraine, those threats have escalated to kinetic attacks that are wreaking havoc on a critical element of our world: agriculture and our global food supply chain. Even worse is the implications this war will have for future cyber attacks, as fragility is considered a lucrative element in deciding victimology by threat actors like ransomware cartels. To truly grasp the implications of the war in Ukraine, we have to examine how vital Ukrainian agriculture feeds the world, the current state of affairs, and what this means for the global cybersecurity posture to protect agricultural assets. Where there is weakness, there is opportunityRansomware cartels and their affiliates are actively targeting the agricultural industry. Moreover, these actors have done their homework and are targeting agricultural companies during the two times of the year where they cannot suffer disruptions: planting and harvesting. Per the published FBI PIN Alert: “Cyber actors may perceive cooperatives as lucrative targets with a willingness to pay due to the time-sensitive role they play in agricultural production.” This is far from unusual for these adversaries - they are shrewd and calculating, and understand their victims' weaknesses and industries.

Volexity researchers discovered SharpExt, a new malicious browser app used by the North-Korea sponsored Velvet Chollima (Kimsuky, SharpTongue, Thallium) group. SharpExt inspects and exfiltrates data from a victim's webmail (AOL or Gmail) account as they browse it. Velvet Chollima continues to add new features to the app, the latest known version (3.0) supports three browsers: Microsoft Edge, Google Chrome, and Whale, the latter almost exclusively used in South Korea. Following the initial compromise, Velvet Chollima deploy SharpExt and to avoid warning the victim they manually exfiltrate settings files to change the settings and generate a valid "super_mac" security check value. They also hide the newly opened DevTools window and any other warning windows such as a warning regarding extensions running in developer mode.
Analyst Comment: Velvet Chollima is known for its tactic of deploying malicious browser extensions, but in the past it was concentrating on stealing credentials instead of emails. The group continues aggressive cyberespionage campaigns exfiltrating military and industrial technologies from Europe, South Korea, and the US. Network defenders should monitor for suspicious instances of PowerShell execution, as well as for traffic to and from known Velvet Chollima infrastructure (available in Anomali Match).

Untangling KNOTWEED: European Private-Sector Offensive Actor Using 0-Day Exploits
(published: July 27, 2022)
Microsoft researchers detail activity of DSIRF, Austrian private-sector offensive actor (PSOA). In 2021, this actor, tracked as Knotweed, used four Windows and Adobe 0-day exploits. In 2022, DSIRF was exploiting another Adobe Reader vulnerability, CVE-2022-22047, which was patched in July 2022. DSIRF attacks rely on their malware toolset called Subzero. The initial downloader shellcode is executed from either the exploit chains or malicious Excel documents. It downloads a JPG image file with extra encrypted data, extracts, decrypts and loads to the memory the Corelump memory-only infostealer. For persistence, Corelump creates trojanized copies of legitimate Windows DLLs that se |
