Detect Unauthorized Processes Making Changes in Your Environment with Qualys File Integrity Monitoring

With the average cost of a data breach exceeding $3.5 million as per Cost of a Data Breach Report, almost all organizations these days adopt stringent policies in order to safeguard their confidential business and customer information. Strong RBAC-driven systems have certainly made it difficult for attackers to gain unauthorized access. However, malicious programs masked as genuine ones can compromise your environment, sneak their way into your databases, and can even allow unauthorized parties to access and/or view information.

LibMiner: Container-Based Cryptocurrency Miner Targeting Unprotected Redis Servers

Qualys is actively tracking threats which target containers. In our recent analysis, we have identified a few docker instances executing a malware which we term as “LibMiner”. This malware has the capability to deploy and execute Cryptominer. It uses a unique technique for lateral movement across the containers as well as Linux systems, executing on unprotected Redis servers and initiating mining on them. The malware has the ability to protect its termination, thus making it impossible to gain control over it. This blog post uncovers the unique techniques and tactics used by LibMiner.

Microsoft Windows CryptoAPI Spoofing Vulnerability (CVE-2020-0601) – How to Detect and Remediate

Update January 27, 2020: Client testing is now available at clienttest.dev.ssllabs.com.

Update January 15, 2020: Detection dashboard now available.

Today, Microsoft released patch for CVE-2020-0601, aka Curveball, a vulnerability in windows “crypt32.dll” component that could allow attackers to perform spoofing attacks. This was discovered and reported by National Security Agency (NSA) Researchers. The vulnerability affects Windows 10 and Windows Server 2016/2019 systems.

This is a serious vulnerability and patches should be applied immediately. An attacker could exploit this vulnerability by using a spoofed code-signing certificate, meaning an attacker could let you download and install malware that pretended to be something legit, such as software updates, due to the spoofed digital signature. Examples where validation of trust may be impacted include:

  • HTTPS connections
  • Signed files and emails
  • Signed executable code launched as user-mode processes
Exploits/PoC:

There are no reports of active exploitation or PoC available in public domain at this point of time. However, per NSA advisory “Remote exploitation tools will likely be made quickly and widely available.”

Citrix ADC and Gateway Remote Code Execution Vulnerability (CVE-2019-19781)

Update January 17, 2020: A new detection in Qualys Web Application Scanning was added. See “Detecting with Qualys WAS” below.

Citrix released a security advisory (CVE-2019-19781) for a remote code execution vulnerability in Citrix Application Delivery Controller (ADC) and Citrix Gateway products. The vulnerability allows an unauthenticated remote attacker to execute arbitrary code on the system. Once exploited, remote attackers could obtain access to private network resources without requiring authentication.

During the week of January 13, attacks on Citrix appliances have intensified. Because of the active attacks and the ease of exploitation, organizations are advised to pay close attention.

Blue is a color we love but can’t Keep!  

Recent reports this year revealed nearly 1 million computer systems are still vulnerable and exposed to BlueKeep in the wild. These systems are still easy targets for an unauthenticated attacker (or malware) to execute code leveraging this patchable vulnerability. Because so many systems are still vulnerable, Qualys has added its BlueKeep dashboard directly into the product, so you can more easily track and remediate this vulnerability.

Streamlining and Automating Compliance

There are seemingly countless regulatory and industry frameworks out there that organizations have to navigate and comply with. SOX (Sarbanes-Oxley), PCI-DSS (Payment Card Industry Data Security Standard), GDPR (General Data Protection Regulation), HIPAA (Health Insurance Portability and Accountability Act), and many others that require maintaining a specified baseline of security. Compliance is a challenge in and of itself, but it is increasingly difficult to maintain compliance with accelerated DevOps lifecycles and complex, hybrid cloud environments.
