Prioritize edge device exposure. Attackers frequently bypass authentication on internet-facing administrative interfaces to gain root access, as seen with Barracuda Email Security Gateways where chained vulnerabilities allowed command injection (The Register, The Register). SonicWall similarly warned of an SSL-VPN flaw that enables MFA bypass, a tactic CISA added to its Known Exploited Vulnerabilities list (TLDR Infosec). Chris Goettl of Ivanti notes that 44% of exploited vulnerabilities reside in edge devices and IT management tools, which require active exposure management rather than standard patching alone (Krebs on Security).
Validate identity and access trust. Qubole recently suffered an incident where an attacker assumed customer cross-account roles to harvest secrets and download data from S3 buckets. Organizations can mitigate such risks by pinning trust policies to specific vendor principals using source IP conditions, preventing unauthorized role assumption. Even when MFA is enforced, attackers increasingly use stolen browser sessions or tokens to maintain access, making session management a critical defense layer (Cybersecurity News by Jose Bolanos MD).
Address fundamental security debt. Organizations often accumulate security tools while neglecting basic operational hygiene like patching and privilege reduction (Rod Trent from Rod’s Blog). Microsoft released nearly 1,100 security updates this month, including a zero-click remote code execution bug in Windows Search that triggers upon automatic indexing (Zero Day Initiative Blog). Despite the volume of patches, security teams struggle to maintain visibility, as shadow IT and unmanaged devices frequently operate outside standard endpoint protections.
- Google patched its eighth actively exploited Chrome zero-day of 2026, a use-after-free vulnerability in the XML component tracked as CVE-2026-125350 (The Register).
- QNAP urges users to update Plex servers on NAS devices to mitigate four actively exploited vulnerabilities that could lead to full system compromise (TLDR Infosec).
- Mozilla Firefox 160 resolves nearly 100 CVEs, with approximately half of the addressed security flaws rated as high severity (Krebs on Security).

Pin your cloud vendor cross-account trust policies to specific source IP ranges.
Identify all active IAM roles that assume trust from third-party vendors and review their current trust policy conditions.
You need
- Access to your cloud provider's IAM console
- List of authorized IP ranges for your vendors
- CloudTrail logs or equivalent access records
Steps
- Query your environment for roles that allow cross-account access from external vendor account IDs.
- Identify which of these roles show no legitimate activity from the vendor in the last 30 days.
- Delete any unused vendor-trusting roles immediately.
- Update the trust policy for remaining vendor roles to include an aws:SourceIp condition.
- Verify that the policy restricts access to the specific IP ranges provided by the vendor.
