  7. Five S3 ransomware variants exploit AWS’s built-in encryption, especially SSE-KMS and SSE-C.
  8. Abuse of imported key material and external key stores allows attackers to control key management.
  9. Researchers recommend hardening S3 with stricter controls and monitoring for suspicious activities.
  10. An “assume breach” approach is vital, emphasizing comprehensive security and backup strategies.

TAKEAWAYS:

  1. Organizations must enhance security protocols around cloud storage, especially AWS S3.
  2. Understanding encryption abuse in cloud environments is crucial to prevent ransomware.
  3. Implementing least privilege access and protective controls is essential for data protection.
  4. Constant monitoring of cloud environments can detect potential ransomware activities.
  5. An “assume breach” mindset ensures preparedness against sophisticated ransomware strategies.

ONE SENTENCE SUMMARY:

A coordinated campaign has spiked malicious scanning on Palo Alto Networks GlobalProtect VPN portals, amplifying security concerns significantly.

MAIN POINTS:

  1. Malicious activity targeting GlobalProtect VPN surged 40 times in one day.
  2. Activity began escalating on November 14, reaching a 90-day high.
  3. October saw a 500% increase in IPs scanning GlobalProtect, 91% suspicious.
  4. April reported 24,000 IPs targeting GlobalProtect, many suspicious.
  5. The surge linked to previous campaigns via fingerprints and timing.
  6. Primary attacks originated from ASNs in Germany and Canada.
  7. 2.3 million sessions targeted VPN logins between November 14 and 19.
  8. Attacks focused on US, Mexico, and Pakistan users.
  9. 80% of scanning spikes precede new security flaw disclosures.
  10. February saw active exploitation of vulnerabilities in Palo Alto Networks.

TAKEAWAYS:

  1. Coordinate security efforts to address escalating VPN portal threats.
  2. Track IP activity patterns to preempt future security disclosures.
  3. Recognize geographical attack concentration for better defense strategies.
  4. Identify imminent threats by examining historical scanning spikes.
  5. Utilize intelligence reports to inform security budget planning.

Velociraptor WSUS Exploitation, Pt. I: WSUS-Up?

Source: Huntress Blog

Author: unknown

URL: https://www.huntress.com/blog/velociraptor-misuse-part-one-wsus-up

ONE SENTENCE SUMMARY:

Threat actors exploited a WSUS vulnerability to install Velociraptor for remote access, increasing incidents of dual-use tool abuse.

MAIN POINTS:

  1. In November, threat actors exploited a WSUS vulnerability (CVE-2025-59287) to gain initial access.
  2. Velociraptor, an open-source tool, was used for command-and-control (C2) communications.
  3. Huntress SOC observed increased misuse of Velociraptor over recent months.
  4. The WSUS vulnerability was patched by Microsoft on October 23.
  5. Cisco Talos linked Velociraptor activity to a SharePoint vulnerability called ToolShell.
  6. Threat actors installed Velociraptor with a malicious MSI from s3.wasabisys.com.
  7. PowerShell commands were used post-installation for system discovery.
  8. Dual-use tools like Cobalt Strike and Mimikatz have been similarly abused.
  9. Velociraptor is part of a larger trend of legitimate tools being misused.
  10. Further insights on Velociraptor misuse will continue in part two of the series.

TAKEAWAYS:

  1. Vigilance is crucial as legitimate tools like Velociraptor are increasingly misused for attacks.
  2. Regular patching can mitigate vulnerabilities, like the recently addressed WSUS flaw.

Active Directory Trust Misclassification: Why Old Trusts Look Like Insecure External Trusts

Source: Tenable Blog

Author: Clément Notin

URL: https://www.tenable.com/blog/active-directory-trust-misclassification-why-old-trusts-look-like-insecure-external-trusts

ONE SENTENCE SUMMARY:

Tenable Research discovered Windows 2000 intra-forest trusts missing a key flag, impacting trust identification across upgraded Active Directory environments.

MAIN POINTS:

  1. Active Directory trusts originating from Windows 2000 may lack proper identification as intra-forest trusts.
  2. The TRUST_ATTRIBUTE_WITHIN_FOREST flag, introduced in Windows 2003, was not retroactively applied.
  3. Upgraded domains maintain zero trust attributes, misidentifying internal trusts as potentially insecure external ones.
  4. CrossRef objects can accurately determine if a trust is intra-forest or external.
  5. External trusts lack a dedicated flag, often appearing as trustAttributes=0.
  6. AD administrative tools may still identify correct trust types despite missing flags.
  7. Tenable conducted lab tests confirming the persistence of the legacy issue.
  8. The issue affects security-analysis tools by confusing internal and external trusts.
  9. New interpretation methods have been validated in real-world environments.
  10. Tenable’s discovery aims to improve trust management in legacy AD environments.

TAKEAWAYS:

  1. Windows 2000 intra-forest trusts may be misidentified due to absent flags.
  2. CrossRef objects offer a solution for identifying trust types.
  3. Upgrades do not resolve missing trust flags in older domains.
  4. Accurate trust interpretation is vital for exposure management tools.
  5. Awareness of this issue aids security professionals in managing legacy AD environments.
