2025-02-11 20:00:00 | Cybercrime: A Multifaceted National Security Threat (lien direct) | Executive Summary Cybercrime makes up a majority of the malicious activity online and occupies the majority of defenders\' resources. In 2024, Mandiant Consulting responded to almost four times more intrusions conducted by financially motivated actors than state-backed intrusions. Despite this overwhelming volume, cybercrime receives much less attention from national security practitioners than the threat from state-backed groups. While the threat from state-backed hacking is rightly understood to be severe, it should not be evaluated in isolation from financially motivated intrusions. A hospital disrupted by a state-backed group using a wiper and a hospital disrupted by a financially motivated group using ransomware have the same impact on patient care. Likewise, sensitive data stolen from an organization and posted on a data leak site can be exploited by an adversary in the same way data exfiltrated in an espionage operation can be. These examples are particularly salient today, as criminals increasingly target and leak data from hospitals. Healthcare\'s share of posts on data leak sites has doubled over the past three years, even as the number of data leak sites tracked by Google Threat Intelligence Group has increased by nearly 50% year over year. The impact of these attacks mean that they must be taken seriously as a national security threat, no matter the motivation of the actors behind it. Cybercrime also facilitates state-backed hacking by allowing states to purchase cyber capabilities, or co-opt criminals to conduct state-directed operations to steal data or engage in disruption. Russia has drawn on criminal capabilities to fuel the cyber support to their war in Ukraine. GRU-linked APT44 (aka Sandworm), a unit of Russian military intelligence, has employed malware available from cybercrime communities to conduct espionage and disruptive operations in Ukraine and CIGAR (aka RomCom), a group that historically focused on cybercrime, has conducted espionage operations against the Ukrainian government since 2022. However, this is not limited to Russia. Iranian threat groups deploy ransomware to raise funds while simultaneously conducting espionage, and Chinese espionage groups often supplement their income with cybercrime. Most notably, North Korea uses state-backed groups to directly generate revenue for the regime. North Korea has heavily targeted cryptocurrencies, compromising exchanges and individual victims\' crypto wallets. Despite the overlaps in effects and collaboration with states, tackling the root causes of cybercrime requires fundamentally different solutions. Cybercrime involves collaboration between disparate groups often across borders and without respect to sovereignty. Any solution requires international cooperation by both law enforcement and intelligence agencies to track, arrest, and prosecute these criminals. Individual takedowns can have important temporary effects, but the collaborative nature of cybercrime means that the disrupted group will be quickly replaced by others offering the same service. Achieving broader success will require collaboration between countries and public and private sectors on systemic solutions such as increasing education and resilience efforts. aside_block | Ransomware Malware Tool Vulnerability Threat Legislation Medical Cloud Technical | APT 41 APT 38 APT 29 APT 43 APT 44 | ★★★ |

2025-01-29 14:00:00 | Adversarial Misuse of Generative AI (lien direct) | Rapid advancements in artificial intelligence (AI) are unlocking new possibilities for the way we work and accelerating innovation in science, technology, and beyond. In cybersecurity, AI is poised to transform digital defense, empowering defenders and enhancing our collective security. Large language models (LLMs) open new possibilities for defenders, from sifting through complex telemetry to secure coding, vulnerability discovery, and streamlining operations. However, some of these same AI capabilities are also available to attackers, leading to understandable anxieties about the potential for AI to be misused for malicious purposes. Much of the current discourse around cyber threat actors\' misuse of AI is confined to theoretical research. While these studies demonstrate the potential for malicious exploitation of AI, they don\'t necessarily reflect the reality of how AI is currently being used by threat actors in the wild. To bridge this gap, we are sharing a comprehensive analysis of how threat actors interacted with Google\'s AI-powered assistant, Gemini. Our analysis was grounded by the expertise of Google\'s Threat Intelligence Group (GTIG), which combines decades of experience tracking threat actors on the front lines and protecting Google, our users, and our customers from government-backed attackers, targeted 0-day exploits, coordinated information operations (IO), and serious cyber crime networks. We believe the private sector, governments, educational institutions, and other stakeholders must work together to maximize AI\'s benefits while also reducing the risks of abuse.

2024-07-25 14:00:00 | APT45: Machine militaire numérique de la Corée du Nord APT45: North Korea\\'s Digital Military Machine (lien direct) |
Written by: Taylor Long, Jeff Johnson, Alice Revelli, Fred Plan, Michael Barnhart
Executive Summary APT45 is a long-running, moderately sophisticated North Korean cyber operator that has carried out espionage campaigns as early as 2009. APT45 has gradually expanded into financially-motivated operations, and the group\'s suspected development and deployment of ransomware sets it apart from other North Korean operators. APT45 and activity clusters suspected of being linked to the group are strongly associated with a distinct genealogy of malware families separate from peer North Korean operators like TEMP.Hermit and APT43. Among the groups assessed to operate from the Democratic People\'s Republic of Korea (DPRK), APT45 has been the most frequently observed targeting critical infrastructure. Overview Mandiant assesses with high confidence that APT45 is a moderately sophisticated cyber operator that supports the interests of the DPRK. Since at least 2009, APT45 has carried out a range of cyber operations aligned with the shifting geopolitical interests of the North Korean state. Although the group\'s earliest observed activities consisted of espionage campaigns against government agencies and defense industries, APT45 has expanded its remit to financially-motivated operations, including targeting of the financial vertical; we also assess with moderate confidence that APT45 has engaged in the development of ransomware. Additionally, while multiple DPRK-nexus groups focused on healthcare and pharmaceuticals during the initial stages of the COVID-19 pandemic, APT45 has continued to target this vertical longer than other groups, suggesting an ongoing mandate to collect related information. Separately, the group has conducted operations against nuclear-related entities, underscoring its role in supporting DPRK priorities. 
Shifts in Targeting and Expanding Operations
Similar to other cyber threat activity attributed to North Korea-nexus groups, shifts in APT45 operations have reflected the DPRK\'s changing priorities. Malware samples indicate the group was active as early as 2009, although an observed focus on government agencies and the defense industry was observed beginning in 2017. Identified activity in 2019 aligned with Pyongyang\'s continued interest in nuclear issues and energy. Although it is not clear if financially-motivated operations are a focus of APT45\'s current mandate, the group is distinct from other North Korean operators in its suspected interest in ransomware. Given available information, it is possible that APT45 is carrying out financially-motivated cybercrime not only in support of its own operations but to generate funds for other North Korean state priorities.

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. |

First-Ever Attack Leveraging Kubernetes RBAC to Backdoor Clusters
(published: April 21, 2023)
A new Monero cryptocurrency-mining campaign is the first recorded case of gaining persistence via Kubernetes (K8s) Role-Based Access Control (RBAC), according to Aquasec researchers. The recorded honeypot attack started with exploiting a misconfigured API server. The attackers preceded by gathering information about the cluster, checking if their cluster was already deployed, and deleting some existing deployments. They used RBAC to gain persistence by creating a new ClusterRole and a new ClusterRole binding. The attackers then created a DaemonSet to use a single API request to target all nodes for deployment. The deployed malicious image from the public registry Docker Hub was named to impersonate a legitimate account and a popular legitimate image. It has been pulled 14,399 times and 60 exposed K8s clusters have been found with signs of exploitation by this campaign.
Analyst Comment: Your company should have protocols in place to ensure that all cluster management and cloud storage systems are properly configured and patched. K8s buckets are too often misconfigured and threat actors realize there is potential for malicious activity. A defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) approach is a good mitigation step to help prevent actors from highly-active threat groups.

3CX Software Supply Chain Compromise Initiated by a Prior Software Supply Chain Compromise; Suspected North Korean Actor Responsible
(published: April 20, 2023)
Investigation of the previously-reported 3CX supply chain compromise (March 2023) allowed Mandiant researchers to detect it was a result of prior software supply chain attack using a trojanized installer for X_TRADER, a software package provided by Trading Technologies. The attack involved the publicly-available tool SigFlip decrypting RC4 stream-cipher and starting publicly-available DaveShell shellcode for reflective loading.

[Eyes on the Prize] How Crafty Cons Attempted a 36 Million Vendor Email Heist
The details in this thwarted VEC attack demonstrate how the use of just a few key details can both establish credibility and indicate the entire thing is a scam.
It\'s not every day you hear about a purely social engineering-based scam taking place that is looking to run away with tens of millions of dollars. But, according to security researchers at Abnormal Security, cybercriminals are becoming brazen and are taking their shots at very large prizes.
This attack begins with a case of VEC – where a domain is impersonated. In the case of this attack, the impersonated vendor\'s domain (which had a .com top level domain) was replaced with a matching .cam domain (.cam domains are supposedly used for photography enthusiasts, but there\'s the now-obvious problem with it looking very much like .com to the cursory glance).
The email attaches a legitimate-looking payoff letter complete with loan details. According to Abnormal Security, nearly every aspect of the request looked legitimate. The telltale signs primarily revolved around the use of the lookalike domain, but there were other grammatical mistakes (that can easily be addressed by using an online grammar service or ChatGPT).
This attack was identified well before it caused any damage, but the social engineering tactics leveraged were nearly enough to make this attack successful. Security solutions will help stop most attacks, but for those that make it past scanners, your users need to play a role in spotting and stopping BEC, VEC and phishing attacks themselves – something taught through security awareness training combined with frequent simulated phishing and other social engineering tests.

What’s With The Shared VBA Code Between Transparent Tribe And Other Threat Actors?
(published: February 9, 2022)
A recent discovery has been made that links malicious VBA macro code between multiple groups, namely: Transparent Tribe, Donot Team, SideCopy, Operation Hangover, and SideWinder. These groups operate (or operated) out of South Asia and use a variety of techniques with phishing emails and maldocs to target government and military entities within India and Pakistan. The code is similar enough that it suggests cooperation between APT groups, despite having completely different goals/targets.
Analyst Comment: This research shows that APT groups are sharing TTPs to assist each other, regardless of motive or target. Files that request content be enabled to properly view the document are often signs of a phishing attack. If such a file is sent to you via a known and trusted sender, that individual should be contacted to verify the authenticity of the attachment prior to opening. Thus, any such file attachment sent by unknown senders should be viewed with the utmost scrutiny, and the attachments should be avoided and properly reported to appropriate personnel.

Fake Windows 11 Upgrade Installers Infect You With RedLine Malware
(published: February 9, 2022)
Due to the recent announcement of Windows 11 upgrade availability, an unknown threat actor has registered a domain to trick users into downloading an installer that contains RedLine malware. The site, "windows-upgraded[.]com", is a direct copy of a legitimate Microsoft upgrade portal. Clicking the 'Upgrade Now' button downloads a 734MB ZIP file which contains an excess of dead code; more than likely this is to increase the filesize for bypassing any antivirus scan. RedLine is a well-known infostealer, capable of taking screenshots, using C2 communications, keylogging and more.
Analyst Comment: Any official Windows update or installation files will be downloaded through the operating system directly. If offline updates are necessary, only go through Microsoft sites and subdomains. Never update Windows from a third-party site due to this type of attack.

[Heads Up] FBI Warns Against New Criminal QR Code Scams
QR codes have been around for many years. While they were adopted for certain niche uses, they never did quite reach their full potential. They are a bit like Rick Astley in that regard, really popular for one song, but well after the boat had sailed. Do not get me wrong, Rick Astley achieved a lot. In recent years, he has become immortalized as a meme and Rick roller, but he could have been so much more.
However, in recent years, with lockdown and the drive to keep things at arms length, QR codes have become an efficient way to facilitate contactless communications, or the transfer of offers without physically handing over a coupon. As this has grown in popularity, more people have become familiar with how to generate their own QR codes and how to use them as virtual business cards, discount codes, links to videos and all sorts of other things.
QRime Codes
As with most things, once they begin to gain a bit of popularity, criminals move in to see how they can manipulate the situation to their advantage. Recently, we have seen fake QR codes stuck to parking meters enticing unwitting drivers to scan the code, and hand over their payment details believing they were paying for parking, whereas they were actually handing over their payment information to criminals.
The rise in QR code fraud resulted in the FBI releasing an advisory warning against fake QR codes that are being used to scam users. In many cases, a fake QR code will lead people to a website that looks like the intended legitimate site. So, the usual verification process of checking the URL and any other red flags apply.
