Ransomware spike tied to potential zero‑day in SonicWall devices

Summary: Multiple incident responders report a surge in intrusions and ransomware deployments leveraging a suspected zero‑day affecting certain SonicWall firewall/VPN appliances. Activity clusters linked to Akira and other ransomware affiliates show rapid lateral movement from edge devices into Windows environments, with evidence of chained exploits and living‑off‑the‑land techniques post‑access. SonicWall customers are advised to apply mitigations, increase monitoring on management interfaces, and validate IPSec/SSL VPN hardening while awaiting definitive vendor guidance.

Suspected exploitation path and victim profile

Recent cases indicate threat actors are obtaining initial access directly through the perimeter device, bypassing conventional MFA prompts for VPN portals under specific configurations. Targeted organizations include mid‑market enterprises with remote access dependencies and legacy management exposure on WAN interfaces. Intrusions often show suppressed logging on the device, complicating forensics.

Post‑exploitation tradecraft

Once inside, operators pivot to domain controllers using credential material harvested from VPN session processes and cached admin accounts. Common follow‑on steps include enumeration via netlogon and PowerShell remoting, deployment of Cobalt Strike or Sliver beacons, and rapid staging of ransomware through PsExec and WMI after disabling EDR drivers with vulnerable‑driver abuse. Data theft precedes encryption, focusing on finance shares and hypervisor datastores.

Indicators and defensive guidance

• Monitor for anomalous VPN logins lacking expected MFA artifacts and for new administrative sessions from firewall‑adjacent subnets.
• Enable full packet capture or span ports on management networks to validate unexpected management plane calls from the appliance.
• Restrict management exposure to a dedicated, non‑routable segment; enforce strong certificate pinning for SSL VPN portals.
• Baseline EDR/AV driver states; alert on unsigned driver loads and service tampering prior to PsExec/WMI proliferation.
• Hunt for sudden SMB enumeration against SYSVOL/NETLOGON followed by creation of local admin accounts across multiple hosts.

What to do now

Apply vendor hardening guidance, rotate VPN and administrative credentials, and validate backups are isolated and restorable. Where feasible, place a temporary ACL in front of SSL VPN portals restricting source IPs and enforce emergency disablement of legacy auth ciphers.

Active exploitation of Microsoft SharePoint flaws fuels intrusions and extortion

Summary: State‑linked actors and cybercriminal groups are actively exploiting recently patched SharePoint vulnerabilities to obtain initial footholds, deploy web shells, and ultimately extort organizations. Intrusions feature server‑side request forgery and deserialization chains, rapid web shell placement under application pools, and data theft from document libraries followed by on‑prem to cloud pivoting.

Initial access via SharePoint application layer

Attackers send crafted HTTP requests to SharePoint front‑end servers to trigger code execution in the application context. Successful exploitation results in web shell deployment within the SharePoint root or temporary directories, often obfuscated as resource or image files, granting persistent command execution.

Privilege escalation and lateral movement

From the application pool, adversaries extract service account credentials, query the configuration database, and pivot to on‑prem AD through unconstrained delegation or misconfigured SPNs. Cloud pivoting occurs via synced identities, targeting Exchange Online and SharePoint Online through compromised OAuth tokens.

Defensive priorities

• Patch SharePoint servers and verify installation with binary/file version checks rather than relying on registry keys alone.
• Scan for web shells in SharePoint content and temp directories; monitor for anomalous w3wp.exe child processes and command interpreters.
• Restrict outbound internet access from SharePoint servers; enable script block logging and centralize IIS logs for anomaly detection.
• Harden service accounts: remove excessive privileges, enforce managed service accounts where possible, and rotate credentials post‑incident.

Incident response actions

Assume credential compromise for SharePoint app pools and any service accounts accessed by the server. Collect memory images to recover transient web shell artifacts, and review Azure AD sign‑in logs for abuse of synchronized identities.

US DOJ settles with Illumina over alleged sale of vulnerable systems to agencies
