Stargazers Ghost Network
Stargazers Ghost Network
  • Check Point Research identified a network of GitHub accounts (Stargazers Ghost Network) that distribute malware or malicious links via phishing repositories. The network consists of multiple accounts that distribute malicious links and malware and perform other actions such as starring, forking, and subscribing to malicious repositories to make them appear legitimate. This network is a highly sophisticated operation that acts as a Distribution as a Service (DaaS). It allows threat actors to share malicious links or malware for distribution through highly victim-oriented phishing repositories. Check Point Research is tracking the threat group behind this service as Stargazer Goblin. The group provides, operates, and maintains the Stargazers Ghost Network and distributes malware and links via their GitHub Ghost accounts. The network distributed all sorts of malware families, including Atlantida Stealer, Rhadamanthys, RisePro, Lumma Stealer, and RedLine. Our latest calculations suggest that more than 3,000 active Ghost accounts are part of the network. Based on core GitHub Ghost accounts, we believe that the network began development or testing on a smaller scale for the first time around August 2022. Check Point Research discovered an advertiser in Dark-Web forums that provides the exact GitHub operation. The first advertisement was published on July 8, 2023, from an account created the previous day. Based on the monitored campaigns from mid-May to mid-June 2024, we estimate that Stargazer Goblin earned approximately $8,000. However, we believe that this amount is only a small fraction of what the actor made during that period. The total amount during the operations’ lifespan is estimated to be approximately $100,000. * Stargazers Ghost Network appears to be only one part of the grand picture, with other Ghost accounts operating on different platforms, constructing an even bigger Distribution as a Service universe.

Resurrecting Internet Explorer: Threat Actors Using Zero-day Tricks in Internet Shortcut File to Lure Victims (CVE-2024-38112)
Resurrecting Internet Explorer: Threat Actors Using Zero-day Tricks in Internet Shortcut File to Lure Victims (CVE-2024-38112)
Check Point Research recently discovered that threat actors have been using novel (or previously unknown) tricks to lure Windows users for remote code execution. Specifically, the attackers used special Windows Internet Shortcut files (.url extension name), which, when clicked, would call the retired Internet Explorer (IE) to visit the attacker-controlled URL. An additional trick on IE is used to hide the malicious .hta extension name. By opening the URL with IE instead of the modern and much more secure Chrome/Edge browser on Windows, the attacker gained significant advantages in exploiting the victim’s computer, although the computer is running the modern Windows 10/11 operating system.

Rafel RAT, Android Malware from Espionage to Ransomware Operations
Rafel RAT, Android Malware from Espionage to Ransomware Operations
Android, Google’s most popular mobile operating system, powers billions of smartphones and tablets globally. Known for its open-source nature and flexibility, Android offers users a wide array of features, customization options, and access to a vast ecosystem of applications through the Google Play Store and other sources. However, with its widespread adoption and open environment comes the risk of malicious activity. Android malware, a malicious software designed to target Android devices, poses a significant threat to users’ privacy, security, and data integrity. These malicious programs come in various forms, including viruses, Trojans, ransomware, spyware, and adware, and they can infiltrate devices through multiple vectors, such as app downloads, malicious websites, phishing attacks, and even system vulnerabilities.

Check Point - Wrong Check Point (CVE-2024-24919)
Check Point - Wrong Check Point (CVE-2024-24919)
Gather round, gather round - it’s time for another blogpost tearing open an SSLVPN appliance and laying bare a recent in-the-wild exploited bug. This time, it is Check Point who is the focus of our penetrative gaze. Check Point, for those unaware, is the vendor responsible for the 'CloudGuard Network Security' appliance, yet another device claiming to be secure and hardened. Their slogan - "you deserve the best security" - implies they are a company you can trust with the security of your network. A bold claim.

Magnet Goblin Targets Publicly Facing Servers Using 1-Day Vulnerabilities
Magnet Goblin Targets Publicly Facing Servers Using 1-Day Vulnerabilities
  • Magnet Goblin is a financially motivated threat actor that quickly adopts and leverages 1-day vulnerabilities in public-facing services as an initial infection vector. At least in one case of Ivanti Connect Secure VPN (CVE-2024-21887), the exploit entered the group’s arsenal as fast as within 1 day after a POC for it was published. Campaigns that we were able to attribute to this actor targeted Ivanti, Magento, Qlink Sense and possibly Apache ActiveMQ. Analysis of the actor’s recent Ivanti Connect Secure VPN campaign revealed a novel Linux version of a malware called NerbianRAT, in addition to WARPWIRE, a JavaScript credential stealer. * The actor’s arsenal also includes MiniNerbian, a small Linux backdoor, and remote monitoring and management (RMM) tools for Windows like ScreenConnect and AnyDesk.

The Risks of the #MonikerLink Bug in Microsoft Outlook and the Big Picture
The Risks of the #MonikerLink Bug in Microsoft Outlook and the Big Picture
Recently, Check Point Research released a white paper titled “The Obvious, the Normal, and the Advanced: A Comprehensive Analysis of Outlook Attack Vectors”, detailing various attack vectors on Outlook to help the industry understand the security risks the popular Outlook app may bring into organizations. As mentioned in the paper, we discovered an interesting security issue in Outlook when the app handles specific hyperlinks. In this blog post, we will share our research on the issue with the security community and help defend against it. We will also highlight the broader impact of this bug in other software.
