Barracuda XDR Report—Akira Ransomware Encrypts in Record 3 Hours
Source: MSP Channel Insights
Tags: ransomware, incident response, threat statistics
Summary:
Barracuda reports that Akira ransomware can go from breach to full encryption in just three hours, and 90% of ransomware incidents exploit a CVE or vulnerable account.
Why it matters:
Highlights rapid escalation in ransomware attacks, reducing the time defenders have to detect and respond.
Editor take:
Akira ransomware is reported to fully encrypt victim environments within three hours of initial breach. Security leaders should review detection and response workflows to ensure the fastest possible containment for ransomware events exploiting CVEs or weak credentials.
Risk: High
Likely impacted
- Organizations with unpatched CVEs
- Environments with weak or stale credentials
- Incident response teams
Actions
- Accelerate patching cycles for known CVEs
- Audit for vulnerable or stale privileged accounts
- Harden credential management and MFA enforcement
- Simulate rapid ransomware scenarios
- Test containment and recovery processes
Emerging Signals
Keycloak WebAuthn Attestation Bypass (CVE-2025-12150) Fix Available
Source: GitLab Advisory Database
Tags: CVE, identity security, authentication
Summary:
Keycloak WebAuthn registration flaw (CVE-2025-12150) allows bypass of attestation policies. Upgrade to version 26.4.4 or later to remediate.
Why it matters:
Weakens authentication integrity and allows forged authenticator registration.
Editor take:
A flaw in Keycloak’s WebAuthn implementation permits bypass of attestation policies, enabling forged authenticator registration. Administrators should apply the version 26.4.4 update promptly to restore authentication integrity.
Risk: Medium
Likely impacted
- Keycloak deployments using WebAuthn
- Federated identity environments
- SSO-integrated applications
Actions
- Upgrade Keycloak to version 26.4.4 or later
- Review authentication policy enforcement
- Monitor for suspicious authenticator registrations
- Harden federation and SSO entry points
Exploits in the Wild / CVEs
Cisco ISE Cloud Auth Bypass CVE-2025-20286 PoC Available
Source: Quorum Cyber
Tags: CVE, cloud auth, proof-of-concept
Summary:
Critical CVE-2025-20286 in Cisco ISE cloud deployments (CVSS 9.9) allows unauthenticated access via reused static credentials. A proof-of-concept exploit is available.
Why it matters:
Risks mass compromise across multi-cloud ISE deployments.
Editor take:
A critical vulnerability in Cisco ISE cloud with a public PoC enables unauthenticated access using static credentials, significantly increasing the likelihood of mass compromise in multi-cloud environments. Immediate patching and credential audits are vital.
Risk: Critical
Likely impacted
- Cisco ISE cloud deployments
- Multi-cloud infrastructure
- Identity and access management teams
Actions
- Apply patches for CVE-2025-20286 without delay
- Audit and rotate static credentials
- Restrict unnecessary cloud access paths
- Monitor for suspicious access attempts

Defensive Actions
- Accelerate patching cycles for all known CVEs, including Cisco ISE (CVE-2025-20286) and Keycloak (CVE-2025-12150), to minimize exposure windows.
- Upgrade Keycloak to version 26.4.4 or later to address the WebAuthn attestation bypass flaw.
- Apply patches for Cisco ISE cloud deployments immediately and audit the presence of static credentials, rotating as necessary.
- Audit privileged, stale, or vulnerable accounts and harden credential lifecycle management.
- Review and deploy strong MFA enforcement organization-wide.
- Simulate rapid ransomware escalation scenarios to validate response workflows.
- Test containment and data recovery processes for effectiveness under compressed timelines.
- Monitor for suspicious authenticator registrations and cloud access attempts in affected environments.
- Harden federation, SSO, and cloud entry points to reduce lateral movement risk.
- Restrict unnecessary cloud access paths and minimize privilege grants where possible.
What we are watching next
- Potential exploitation spikes following public proof-of-concept (PoC) code for critical authentication CVEs.
- Vendor responses and additional patches related to identity infrastructure vulnerabilities.
- Ransomware dwell time trends and advancements in rapid detection and containment tooling.
