CVE-2026-55040, a critical SharePoint authentication bypass, is now being actively exploited. A proof-of-concept went public on August 11. Within 24 hours, threat intelligence firm Defused confirmed exploitation attempts against its SharePoint honeypots using that same PoC. Over 8,500 SharePoint servers remain reachable from the open internet, putting unpatched instances at immediate risk.

WhatsApp has begun rolling out usernames, letting people connect without sharing their phone number. The feature adds privacy for individual users but opens fresh territory for impersonation, lookalike accounts, and smishing, particularly as usernames are reserved on a country-by-country basis.

FedRAMP moved POA&Ms to agencies and replaced them with Accepted Weaknesses under the 2026 rules. Cloud providers must evaluate vulnerabilities in context (criticality, reachability, exploitability, detectability, prevalence, privilege, proximity, known threats), report results in JSON with PAIN N1–N5 ratings, and assume attacker automation. Remediate high PAIN, internet reachable risks fast; low PAIN risks can be accepted. Machine-readable data and platforms can help meet requirements.

Most organizations that try to write an AI security policy start with two lists. Approved tools and banned tools. But, that list is inevitably out of date within a month. Employees adopt AI features embedded in everyday software faster than any review board can evaluate them, and a blanket ban does not stop the behavior, instead it pushes people toward personal accounts and unmanaged services.

Under India's Digital Personal Data Protection (DPDP) Act, 2023, every organization that handles personal data falls into one of two roles: data fiduciary or data processor. A data fiduciary decides why and how personal data is processed. A data processor carries out those instructions on the fiduciary's behalf, with no independent decision-making authority. The distinction matters because the DPDP Act ties accountability, liability, and contractual duty directly to which role you occupy.

EDR (endpoint detection and response) works by deploying sensors on protected endpoints to continuously collect selected behavioral telemetry, forwarding that telemetry to a centralized analytics layer, commonly cloud-hosted, that applies detection rules, behavioral analytics, machine learning and threat intelligence, and surfacing prioritized incidents in a console where analysts can investigate and respond.
