  • CVE-2019-7238: Insufficient Access Controls in Sonatype Nexus Repository Manager 3 Allows Remote Code Execution

    Trend Micro - Security Intelligence
    A critical remote code execution (RCE) vulnerability (CVE-2019-7238) was found in Sonatype’s Nexus Repository Manager (NXRM) 3, an open source project that allows developers, such as DevOps professionals, to manage software components required for software development, application deployment, and automated hardware provisioning.

  • A Machine Learning Model to Detect Malware Variants

    Trend Micro - Security Intelligence
    When malware is difficult to discover — and has limited samples for analysis — we propose a machine learning model that uses adversarial autoencoder and semantic hashing to find what bad actors try to hide. We, along with researchers from the Federation University Australia, discussed this model in our study titled “Generative Malware Outbreak Detection.”

  • March’s Patch Tuesday Fixes Privilege Escalation Vulnerabilities Exploited in the Wild

    Trend Micro - Security Intelligence
    Microsoft’s Patch Tuesday for March addressed 64 vulnerabilities, 17 of which were rated critical, 45 important, one moderate, and another low in severity. Two of these vulnerabilities, CVE-2019-0797 and CVE-2019-0808, were reported to have been actively exploited in the wild. The patches addressed security flaws in a number of Microsoft products and services: .NET Framework, Edge, Exchange, Internet Explorer, Office, Office Services and Web Apps, NuGet, Team Foundation Server, and Windows. Seven of the vulnerabilities were disclosed via Trend Micro’s Zero Day Initiative (ZDI).

  • From Fileless Techniques to Using Steganography: Examining Powload’s Evolution

    Trend Micro - Security Intelligence
    In some of the recent Powload-related incidents we saw, we noticed significant changes to some of the attachments in the spam emails: the use of steganography and targeting of specific countries. Figure 2 shows the difference. For example, the samples we analyzed in early 2018 had more straightforward infection chains. These updates added another stage to the execution of malicious routines as a way to evade detection.
    The Powload variants that use these techniques drop and execute the Ursnif and Bebloh data stealers. We did not see any notable differences in the payloads’ routines. The distribution tactics also resemble a spam campaign we uncovered last year, which delivered the same information stealers but distributed via the Cutwail botnet.

  • New SLUB Backdoor Uses GitHub, Communicates via Slack

    Trend Micro - Security Intelligence
    We discovered a malware that uses three different online services -- including Slack and GitHub-- as part of its routine. Analysis of the attacker's tools, techniques, and procedures lead us to believe that this might be a targeted attack from very capable threat actors.

  • UPnP-enabled Connected Devices in the Home and Unpatched Known Vulnerabilities

    Trend Micro - Security Intelligence
    Many devices such as cameras, printers, and routers use UPnP to make it easy for them to automatically discover and vet other devices on a local network and communicate with each other for data sharing or media streaming. UPnP works with network protocols to configure communications in the network. But with its convenience comes security holes that range from attackers gaining control of devices to bypassing firewall protections.
    We looked into UPnP-related events in home networks and found that many users still have UPnP enabled in their devices.

  • Exposed IoT Automation Servers and Cybercrime

    Trend Micro - Security Intelligence
    In our latest research we tested possible threat scenarios against complex IoT environments such as in smart homes and smart buildings. A significant part of the research also involved a look into exposed automation platforms or servers, which are integral components of complex IoT environments.

  • Fileless Banking Trojan Targeting Brazilian Banks Downloads Possible Botnet Capability, Info Stealers

    Trend Micro - Security Intelligence
    We analyzed a fileless banking trojan targeting three major banks in Brazil and their customers, downloading info stealers, keyloggers and a hack tool. Infected machines can be used for a botnet and mass mailed targeted attacks, and our telemetry recorded the highest infection attempts from Brazil and Taiwan.

  • Exposed Docker Control API and Community Image Abused to Deliver Cryptocurrency-Mining Malware

    Trend Micro - Security Intelligence
    Through data analysis of the container honeypots we’ve set up to monitor threats, we’ve uncovered notable activities of undesired or unauthorized cryptocurrency miners being deployed as rogue containers using a community-contributed container image published on Docker Hub. The image is being abused as part of a malicious service that delivers cryptocurrency-mining malware. Networking tools are retrieved to carry out lateral movement on other exposed containers and applications.
    The activities we uncovered are also significant in that they don’t need to exploit vulnerabilities and don’t depend on any version of Docker. Identifying a misconfigured and thus exposed container image is all it could take for attackers to infect many exposed hosts.

  • Shifting Strategies: Using Social Media, SEO in Tech Support Scams

    Trend Micro - Security Intelligence
    Tech support scams have diversified into new territory. They now use pop-up alerts and social engineering tactics to spread fake toll-free numbers and links of their fake tech support websites on popular social media platforms.
