Russian Router Campaign Turns SNMP Into a Critical Infrastructure Risk
NSA, CISA, the FBI, and 15 allied agencies warn that Russian FSB Center 16 actors are still compromising poorly configured routers across critical infrastructure. The practical fix starts with SNMPv3, blocked management protocols, patched firmware, and a hard look at exposed network devices.
SharePoint’s New Exploited RCE Turns Patching Into Key Rotation Triage
CISA added Microsoft SharePoint Server CVE-2026-58644 to its exploited-vulnerabilities catalog on July 16, two days after Microsoft patched it. Admins should patch, verify AMSI, hunt for machine-key theft, and reduce internet exposure before treating the farm as clean.
Signal Backup-Key Phishing Turns Account Recovery Into an Espionage Target
The FBI and CISA warn that Russian intelligence-linked actors are impersonating messaging-app support accounts to steal Signal backup recovery keys, verification codes, and account PINs. The attacks do not break encryption, but they can expose message backups and keep account-takeover paths alive until users replace compromised keys.
iDirect Satellite Terminal Flaws Put Link Management on the Patch List
CISA says ST Engineering iDirect iQ-Series satellite terminals running software 4.5.2.1 or earlier expose sensitive device identifiers and can be forced into reboots through weak API controls. Operators should treat the July 2 advisory as both a patch event and a management-plane exposure audit.
SharePoint RCE Gives Admins a July 4 Patch Deadline
CISA has added Microsoft SharePoint Server CVE-2026-45659 to its exploited-vulnerabilities catalog, giving federal agencies until July 4 to apply mitigations and run forensic triage. The flaw was patched in May, but active exploitation means on-prem SharePoint teams should verify builds, review exposure, and check for compromise now.
BlueHammer Ransomware Flag Puts Microsoft Defender Patching Back on the Clock
CISA has updated the Microsoft Defender BlueHammer flaw, CVE-2026-33825, to mark it as used in ransomware campaigns. The flaw was patched in April, but the new flag gives Windows teams a fresh reason to verify Defender updates, endpoint telemetry, and local privilege escalation controls.
Daktronics Controller Flaws Put Public Digital Signs on Patch Watch
CISA is warning that flaws in Daktronics DMP-5000, VFC-DMP-5000, and DMP-8000 controller firmware could expose public display systems to root-level compromise. Operators of billboards, highway signs, venues, hospitals, and other connected displays should patch firmware, change default credentials, and verify that controllers are not reachable from the open internet.
PTC Windchill Exploits Put Manufacturing PLM Systems on Patch Clock
CISA added CVE-2026-12569, a critical PTC Windchill and FlexPLM remote code execution flaw, to its Known Exploited Vulnerabilities catalog with a June 28 deadline. The bug is being used to deploy JSP web shells against product lifecycle management systems that often sit deep inside manufacturing and engineering workflows.
CISA Gives UniFi OS and Lantronix Flaws a June 26 Patch Deadline
CISA added three Ubiquiti UniFi OS flaws and a Lantronix EDS5000 code-injection bug to its Known Exploited Vulnerabilities catalog, setting a June 26 remediation deadline for federal agencies. The risk is not just another CVE list: exposed network management interfaces can become a fast path to device control.
CISA’s June 23 Deadline Puts Cisco SD-WAN, Chrome, and Arista EOS on the Triage List
CISA’s June 23 remediation deadline covers three actively exploited flaws across Cisco Catalyst SD-WAN Manager, Google Chrome’s V8 engine, and Arista EOS. The useful move for security teams is not treating them as one patch chore, but triaging each layer: network control plane, browsers, and tunnel decapsulation paths.
