Alleged 10PB Breach Targets China Supercomputing Hub
|
Threat actors claim a 10-petabyte data theft from China’s Tianjin supercomputing hub, which supports thousands of academic, industrial, and defense entities.
If confirmed, the breach could expose sensitive assets like missile designs and classified research, with the attack reportedly starting from a compromised VPN domain.
|
China has not yet confirmed if the threat actor claims are accurate.
Enforce MFA on VPNs, segment networks with least privilege, monitor for anomalous activity, and use DLP tools.

Palo Alto Networks Cortex Flaw Exposes Sensitive Data
|
A vulnerability in Palo Alto Networks’ Cortex platform could allow attackers to access and manipulate sensitive data without authentication through a flawed Microsoft Teams integration.
Affecting Cortex XSOAR and XSIAM, the flaw allows attackers to impersonate trusted components and manipulate incident response workflows.
Palo Alto Networks has released a patch for the vulnerability.
Apply the latest patch, restrict integration access with strong authentication and IP allowlisting, and monitor logs and build playbooks for suspicious or unauthorized activity.

AWS Patches RES RCE Vulnerabilities
|
AWS has patched high-severity flaws in its Research and Engineering Studio (RES) that could let authenticated attackers execute root commands and escalate privileges.
The vulnerabilities put sensitive workloads at risk of data exposure and lateral movement, with potential to disrupt operations and extend access across AWS environments.
AWS reported that no exploitation has been seen in the wild at the time of publication.
Immediately upgrade RES, restrict API access with strong controls, enforce least privilege on IAM roles, and monitor for anomalous command or API activity.

Security Tools You Can Use

|
|
SonicWall Vulnerabilities Enable Privilege Escalation
|
Multiple vulnerabilities in SonicWall SMA1000 appliances could let attackers escalate privileges, bypass MFA, and enumerate user credentials.
The flaws potentially enable full administrative control through chained exploitation.
|
No exploitation has been reported yet in the wild.
Apply the latest patches, restrict external access with allowlisting or zero trust controls, and monitor for suspicious login or privilege escalation activity.
|
GitLab Flaws Enable DoS, Code Injection
|
GitLab has released patches for flaws that could enable DoS attacks and unintended code execution in self-managed environments.
The vulnerabilities impact both Community and Enterprise editions, risking disrupted pipelines, exposed code, and compromised CI/CD workflows.
GitLab has deployed fixes in hosted environments, but urges patching for self-managed deployments.
Apply the latest patches, use DoS protections and monitor for suspicious activity.

Are You Overlooking Cloud Security Gaps?
|
Cloud environments continue to be targets, with misconfigurations and over-permissive access driving many incidents.
As organizations expand across multi-cloud and SaaS environments, gaps in visibility and identity management create opportunities for attackers to exploit exposed assets.
|
How to strengthen your cloud security posture:
|
- Enforce least privilege and strong identity controls by limiting access, applying MFA, using identity federation, and implementing PAM solutions.
- Use CSPM and CNAPP tools to detect misconfigurations, compliance gaps, and security risks across cloud environments.
- Monitor activity logs, segment resources, and audit storage permissions to detect suspicious behavior and data exposure.
|
Effective cloud security requires continuous visibility and control, combining strong access management, activity monitoring, and proactive risk detection to reduce exposure.
