## Snapshot Last week\'s OSINT reporting reveals a diverse range of cyber threats targeting organizations globally. The articles highlight various attack vectors, including phishing emails with malware payloads (SSLoad, [Cobalt Strike](https://security.microsoft.com/intel-profiles/fd8511c1d61e93d39411acf36a31130a6795efe186497098fe0c6f2ccfb920fc)), ransomware variants (KageNoHitobito, DoNex), and mobile banking malware (Brokewell) distributed through fake domain schemes and overlay attacks. Threat actors behind these campaigns range from financially motivated ransomware groups to sophisticated state-sponsored actors like Sandworm ([Seashell Blizzard](https://sip.security.microsoft.com/intel-profiles/cf1e406a16835d56cf614430aea3962d7ed99f01ee3d9ee3048078288e5201bb)) and UAT4356 ([Storm-1849](https://sip.security.microsoft.com/intel-profiles/f3676211c9f06910f7f1f233d81347c1b837bddd93292c2e8f2eb860a27ad8d5)). Targetted organizations span Europe, Asia, and the Americas and targetted industries include critical infrastructure and IT. ## Description 1. **[Ongoing FROZEN#SHADOW Phishing Campaign](https://security.microsoft.com/intel-explorer/articles/e39d9bb3)**: The FROZEN#SHADOW campaign utilizes phishing emails to distribute SSLoad malware, alongside [Cobalt Strike](https://security.microsoft.com/intel-profiles/fd8511c1d61e93d39411acf36a31130a6795efe186497098fe0c6f2ccfb920fc) and ConnectWise ScreenConnect for extensive persistence and remote access. The victim organizations, predominantly in Europe, Asia, and the Americas, are targeted via JavaScript file downloads and MSI installers connecting to attacker-controlled domains. 2. **[Insights on KageNoHitobito and DoNex Ransomware](https://security.microsoft.com/intel-explorer/articles/ff848e92)**: KageNoHitobito and DoNex are ransomware variants with distinct encryption methods and ransom note presentations. While KageNoHitobito prompts victims to negotiate through a TOR site, DoNex terminates specific services and processes, deletes shadow copies, and may be linked to DarkRace ransomware. 3. **[Brokewell Mobile Banking Malware](https://security.microsoft.com/intel-explorer/articles/99a5deee)**: Brokewell poses a significant threat to the banking industry, utilizing overlay attacks, spyware functionalities, and remote control capabilities to steal credentials and device information. The malware\'s active development and promotion on underground channels indicate a growing interest among cybercriminals targeting different regions. 4. **[Malvertising Campaign Targeting IT Teams with MadMxShell](https://security.microsoft.com/intel-explorer/articles/ffa6ca10)**: A sophisticated threat actor distributes the MadMxShell backdoor through fake domains, using Google Ads to push them to the top of search results. MadMxShell employs complex evasion techniques, including multi-stage injection and DNS tunneling for C2 communication, indicating an interest in targeting IT professionals for unauthorized access. 5. **[ArcaneDoor Campaign by UAT4356 (Storm-1849)](https://security.microsoft.com/intel-explorer/articles/a0cf0328)**: UAT4356 (tracked by Microsoft as [Storm-1949](https://sip.security.microsoft.com/intel-profiles/f3676211c9f06910f7f1f233d81347c1b837bddd93292c2e8f2eb860a27ad8d5)) targets perimeter network devices like Cisco Adaptive Security Appliances (ASA) with backdoors "Line Runner" and "Line Dancer" for reconnaissance and malicious actions. The campaign showcases a state-sponsored actor\'s advanced tradecraft, with deliberate efforts to evade forensics and exploit 0-day vulnerabilities. The initial access vector used in this campaign remains unidentified, but two vulnerabilities ([CVE-2024-20353](https://security.microsoft.com/intel-explorer/cves/CVE-2024-20353/description) and[CVE-2024-20359](https://security.microsoft.com/intel-explorer/cves/CVE-2024-20359/description)) were exploited. 6. **[Kapeka Backdoor Linked to Sandworm (Seashell Blizzard)](https://security.microsoft.com/intel-explorer/articles/364efa92)**: Kapeka (tracked by Microsoft as K | Ransomware Malware Tool Vulnerability Threat Mobile Industrial | ★★★ | |

#### Targeted Geolocations - Oceania - Southeast Asia - South Asia - East Asia - Central Asia #### Targeted Industries - Government Agencies & Services - Defense ## Snapshot Kaspersky reports the APT group ToddyCat has been observed targeting governmental organizations, particularly defense-related ones in the Asia-Pacific region, with the goal of stealing sensitive information on an industrial scale. ## Description They employ various tools and techniques, including traffic tunneling and the creation of reverse SSH tunnels, to maintain constant access to compromised infrastructure. The attackers utilize disguised OpenSSH private key files, execute scripts to modify folder permissions, create SSH tunnels to redirect network traffic, and employ the SoftEther VPN package to potentially facilitate unauthorized access and data exfiltration. Additionally, they use various files and techniques, such as concealing file purposes, copying files through shared resources, and tunneling to legitimate cloud providers, to gain access to victim hosts and evade detection. The threat actors initially gain access to systems by installing servers, modifying server settings, and utilizing tools like Ngrok and Krong to redirect C2 traffic and create tunnels for unauthorized access. They also employ the FRP client, a data collection tool named "cuthead", and a tool called "WAExp" to search for and collect browser local storage files containing data from the web version of WhatsApp. The attackers demonstrate a sophisticated and evolving approach to data collection and exfiltration, utilizing multiple tools and techniques to achieve their objectives. ## Recommendations Microsoft recommends the following mitigations to reduce the impact of Information stealer threats. - Check your Office 365 email filtering settings to ensure you block spoofed emails, spam, and emails with malware. Use [Microsoft Defender for Office 365](https://learn.microsoft.com/microsoft-365/security/office-365-security/defender-for-office-365?ocid=magicti_ta_learndoc) for enhanced phishing protection and coverage against new threats and polymorphic variants. Configure Microsoft Defender for Office 365 to [recheck links on click](https://learn.microsoft.com/microsoft-365/security/office-365-security/safe-links-about?ocid=magicti_ta_learndoc) and [delete sent mail](https://learn.microsoft.com/microsoft-365/security/office-365-security/zero-hour-auto-purge?ocid=magicti_ta_learndoc) in response to newly acquired threat intelligence. Turn on [safe attachments policies](https://learn.microsoft.com/microsoft-365/security/office-365-security/safe-attachments-policies-configure?ocid=magicti_ta_learndoc) to check attachments to inbound email. - Encourage users to use Microsoft Edge and other web browsers that support SmartScreen, which identifies and blocks malicious websites, including phishing sites, scam sites, and sites that host malware. - Turn on [cloud-delivered protection](https://learn.microsoft.com/microsoft-365/security/defender-endpoint/configure-block-at-first-sight-microsoft-defender-antivirus?ocid=magicti_ta_learndoc) in Microsoft Defender Antivirus, or the equivalent for your antivirus product, to cover rapidly evolving attacker tools and techniques. Cloud-based machine learning protections block a majority of new and unknown variants. - Enforce MFA on all accounts, remove users excluded from MFA, and strictly [require MFA](https://learn.microsoft.com/azure/active-directory/identity-protection/howto-identity-protection-configure-mfa-policy?ocid=magicti_ta_learndoc) from all devices, in all locations, at all times. - Enable passwordless authentication methods (for example, Windows Hello, FIDO keys, or Microsoft Authenticator) for accounts that support passwordless. For accounts that still require passwords, use authenticator apps like Microsoft Authenticator for MFA.

2024-04-05 13:39:39 | Même cibles, nouveaux manuels: les acteurs de la menace en Asie de l'Est utilisent des méthodes uniques Same targets, new playbooks: East Asia threat actors employ unique methods (lien direct) |
## Snapshot Microsoft has observed several notable cyber and influence trends from China and North Korea since June 2023 that demonstrate not only doubling down on familiar targets, but also attempts to use more sophisticated influence techniques to achieve their goals. Chinese cyber actors broadly selected three target areas over the last seven months. - One set of Chinese actors extensively targeted entities across the South Pacific Islands. - A second set of Chinese activity continued a streak of cyberattacks against regional adversaries in the South China Sea region. - Meanwhile, a third set of Chinese actors compromised the US defense industrial base. Chinese influence actors-rather than broadening the geographic scope of their targets-honed their techniques and experimented with new media. Chinese influence campaigns continued to refine AI-generated or AI-enhanced content. The influence actors behind these campaigns have shown a willingness to **both amplify AI-generated media that benefits their strategic narratives, as well as create their own video, memes, and audio content**. Such tactics have been used in campaigns stoking divisions within the United States and exacerbating rifts in the Asia-Pacific region-including Taiwan, Japan, and South Korea. These campaigns achieved varying levels of resonance with no singular formula producing consistent audience engagement. North Korean cyber actors made headlines for **increasing software supply chain attacks and cryptocurrency heists over the past year**. While strategic spear-phishing campaigns targeting researchers who study the Korean Peninsula remained a constant trend, North Korean threat actors appeared to make greater use of legitimate software to compromise even more victims. ## Activity Overview ### Chinese cyber operations target strategic partners and competitors #### Gingham Typhoon targets government, IT, and multinational entities across the South Pacific Islands **** *Figure 1: Observed events from Gingham Typhoon from June 2023 to January 2024 highlights their continued focus on South Pacific Island nations. However, much of this targeting has been ongoing, reflecting a yearslong focus on the region. Geographic locations and diameter of symbology are representational. * During the summer of 2023, Microsoft Threat Intelligence observed extensive activity from China-based espionage group Gingham Typhoon that targeted nearly every South Pacific Island country. Gingham Typhoon is the most active actor in this region, hitting international organizations, government entities, and the IT sector with complex phishing campaigns. Victims also included vocal critics of the Chinese government. Diplomatic allies of China who were victims of recent Gingham Typhoon activity include executive offices in government, trade-related departments, internet service providers, as well as a transportation entity. Heightened geopolitical and diplomatic competition in the region may be motivations for these offensive cyber activities. China pursues strategic partnerships with South Pacific Island nations to expand economic ties and broker diplomatic and security agreements. Chinese cyber espionage in this region also follows economic partners. For example, Chinese actors engaged in large-scale targeting of multinational organizations in Papua New Guinea, a longtime diplomatic partner that is benefiting from multiple Belt and Road Initiative (BRI) projects including the construction of a major highway which links a Papua New Guinea government building to the capital city\'s main road.

#### Description Volexity has uncovered active in-the-wild exploitation of two vulnerabilities allowing unauthenticated remote code execution in Ivanti Connect Secure VPN devices. An official security advisory and knowledge base article have been released by Ivanti that includes mitigation that should be applied immediately. The vulnerabilities allow unauthenticated remote code execution and have been assigned the following CVEs: CVE-2023-46805 and CVE-2024-21887. The attacker leveraged these exploits to steal configuration data, modify existing files, download remote files, and reverse tunnel from the ICS VPN appliance. Volexity discovered that the attacker was placing webshells on multiple internal and external-facing web servers. The attacker modified a legitimate CGI file (compcheckresult.cgi) on the ICS VPN appliance to allow command execution. Further, the attacker also modified a JavaScript file used by the Web SSL VPN component of the device in order to keylog and exfiltrate credentials for users logging into it. Volexity currently attributes this activity to an unknown threat actor it tracks under the alias UTA0178. #### Reference URL(s) 1. https://www.cisa.gov/news-events/alerts/2024/01/10/ivanti-releases-security-update-connect-secure-and-policy-secure-gateways 2. https://www.volexity.com/blog/2024/01/10/active-exploitation-of-two-zero-day-vulnerabilities-in-ivanti-connect-secure-vpn/ #### Publication Date January 11, 2024 #### Author(s) Matthew Meltzer Robert Jan Mora Sean Koessel Steven Adair Thomas Lancaster |
