## Snapshot Last week\'s OSINT reporting reveals a persistent focus on sophisticated cyber espionage and ransomware campaigns by state-sponsored threat actors and advanced cybercriminal groups. Key trends include the exploitation of known vulnerabilities in network devices and hypervisors by Chinese groups like Velvet Ant and UNC3886, leveraging custom malware for long-term access and data theft. Meanwhile, actors active in the Middle Eastern and South Asian such as Arid Viper and UTA0137 continue to target adversaries with trojanized apps and Linux malware, respectively. Additionally, innovative social engineering techniques, like those used by TA571 and ClearFake, highlight the evolving methods threat actors employ to deliver diverse payloads, including ransomware and information stealers. The consistent targeting of critical infrastructure, government entities, and high-value enterprises underscores the need for robust, multi-layered cybersecurity defenses to mitigate these sophisticated and persistent threats. ## Description 1. **[Arid Viper Espionage Campaigns](https://sip.security.microsoft.com/intel-explorer/articles/19d9cd7d)**: ESET researchers uncovered Arid Viper\'s espionage campaigns targeting Android users in Egypt and Palestine. The campaigns distribute trojanized apps through dedicated websites, focusing on user data espionage with their AridSpy malware, a sophisticated multistage Android spyware. 2. **[Velvet Ant Exploits F5 BIG-IP](https://sip.security.microsoft.com/intel-explorer/articles/e232b93d)**: Sygnia analysts revealed that the Chinese cyberespionage group Velvet Ant exploited vulnerabilities in F5 BIG-IP appliances to deploy malware like PlugX, enabling long-term access and data theft. These incidents emphasize the threat posed by persistent threat groups exploiting network device vulnerabilities. 3. **[UNC3886 Targets Hypervisors](https://sip.security.microsoft.com/intel-explorer/articles/faed9cc0)**: Google Cloud reported that Mandiant investigated UNC3886, a suspected Chinese cyberespionage group, targeting hypervisors with sophisticated malware and exploiting vulnerabilities in FortiOS and VMware technologies. The group utilized rootkits and custom malware for persistence and command and control. 4. **[UTA0137 Cyber-Espionage Campaign](https://sip.security.microsoft.com/intel-explorer/articles/bc2b5c55)**: Volexity identified Pakistan-based UTA0137 targeting Indian government entities with DISGOMOJI malware, which uses Discord for command and control. The campaign targets Linux systems, employing various persistence mechanisms and exploiting vulnerabilities like DirtyPipe for privilege escalation. 5. **[Proofpoint Highlights Copy-Paste Attacks](https://sip.security.microsoft.com/intel-explorer/articles/c75089e9)**: Proofpoint researchers reported that threat actors, including TA571 and ClearFake, are using techniques that prompt users to copy and paste malicious PowerShell scripts. These campaigns deliver various malware, including DarkGate and NetSupport, through clever social engineering tactics that trick users into compromising their systems. 6. **[Shinra and Limpopo Ransomware](https://sip.security.microsoft.com/intel-explorer/articles/b7a96cbd)**: FortiGuard Labs identified the emergence of Shinra and Limpopo ransomware strains in early 2024. Shinra ransomware exfiltrates data before encryption, while Limpopo targets ESXi environments, affecting multiple countries and causing significant disruptions. 7. **[CVE-2024-4577 Vulnerability Exploits](https://sip.security.microsoft.com/intel-explorer/articles/8635c515)**: Cyble Global Sensor Intelligence detected multiple scanning attempts exploiting CVE-2024-4577, a vulnerability in Windows affecting PHP installations. Threat actors are using this flaw to deploy ransomware and malware, emphasizing the urgent need for organizations to upgrade PHP versions to mitigate risks. 8. **[SmallTiger Malware Targets South Korea](https://sip.security.microsoft.com/intel-explorer/articles/3f29a6c8)**: The AhnLab Securi | Ransomware Malware Tool Vulnerability Threat Mobile Cloud | APT-C-23 | |

New SolarMaker (Jupyter) Campaign Demonstrates the Malware’s Changing Attack Patterns
(published: April 8, 2022)
Palo Alto Researchers have released their technical analysis of a new version of SolarMaker malware. Prevalent since September 2020, SolarMaker’s initial infection vector is SEO poisoning; creating malicious websites with popular keywords to increase their ranking in search engines. Once clicked on, an encrypted Powershell script is automatically downloaded. When executed, the malware is installed. SolarMaker’s main functionality is the theft of web browser information such as stored passwords, auto-fill data, and saved credit card information. All the data is sent back to an encoded C2 server encrypted with AES. New features discovered by this technical analysis include increased dropper file size, droppers are always signed with legitimate certificates, a switch back to executables instead of MSI files. Furthermore, the backdoor is now loaded into the dropper process instead of the Powershell process upon first time execution.
Analyst Comment: Never click on suspicious links, always inspect the url for any anomalies. Untrusted executables should never be executed, nor privileges assigned to them. Monitor network traffic to assist in the discovery of non standard outbound connections which may indicate c2 activity.

Google is on Guard: Sharks shall not Pass!
(published: April 7, 2022)
Check Point researchers have discovered a series of malicious apps on the Google Play store that infect users with the info stealer Sharkbot whilst masquerading as AV products. The primary functionality of Sharkbot is to steal user credentials and banking details which the user is asked to provide upon launching the app. Furthermore, Sharkbot asks the user to permit it a wide array of permissions that grant the malware a variety of functions such as reading and sending SMS messages and uninstalling other applications. Additionally, the malware is able to evade detection through various techniques. Sharkbot is geofenced, therefore it will stop functioning if it detects the user is from Belarus, China, India, Romania, Russia or Ukraine. Interestingly for Android malware, Sharkbot also utilizes domain generation algorithm (DGA). This allows the malware to dynamically generate C2 domains to help the malware function after a period of time even i |
