API rate limiting protects capacity and user experience. This guide shows how to ship it correctly on NGINX: define limit_req zones, tune burst/nodelay, add per-IP and per-token limits, return proper 429s with Retry-After, and combine limit_conn for connection abuse. You’ll get production-ready snippets and a safe rollout plan.
Gootloader is active again. Attackers poison search results for legal templates, hide content with glyph-mapped fonts, and ship malformed ZIP files that drop JavaScript. The post-compromise tempo increases, so defenders must harden browsers, restrict scripts, and tune detections now.
Spin up a free SIEM home lab this weekend. You’ll deploy Wazuh or OpenSearch, collect Windows telemetry with Sysmon, and run Sigma detections you can actually see and tune. This guide prioritizes students and hobbyists: minimal hardware, copy-paste steps, and safe tests so you learn detection engineering not just dashboards.
Seven fresh techniques let attackers leak ChatGPT data through everyday workflows: poisoned search, “q=” one-click links, allowlisted ad redirects, conversation injection, markdown hiding, and memory poisoning. Because exposure rides on normal browsing and memory behavior, prevention requires policy plus proof: sanitize URLs, block bing.com/ck/a, disable Saved Memory for high-risk roles, and validate controls continuously with OWASP LLM Top 10 and MITRE ATLAS as your benchmarks.
NGAV (next-gen antivirus) focuses on stopping malware and exploits with AI and behavior analysis. EDR adds continuous visibility, investigation, and one-click response when prevention misses. For most SMEs, start with a strong NGAV baseline and move to EDR as soon as you can support alerts and response especially if ransomware or hands-on-keyboard attacks worry you. …
Iran-aligned operators ran a precise phishing campaign against US policy experts. They impersonated scholars, redirected victims to prefilled Microsoft 365 pages, and, when blocked, installed remote-access tools. The goal: long-term visibility into policy drafts, research, and contacts—achieved through identity abuse, inbox rules, and pragmatic persistence.
A trivial surveillance password created an opening at one of the world’s most prominent institutions. Intruders gained awareness and timed their move because credential policy failed. This analysis delivers the signals, mitigations, and governance disciplines that stop repeats: rotation, MFA, segmentation, PAM for service accounts, and continuous validation for VMS and NVR stacks—without resorting to list spam or generic advice.
Criminal crews deploy legitimate RMM tools inside carriers and brokers, then hijack booking and dispatch to steal real freight. This body explains how access lands, which artifacts reveal the intrusion, and what controls stop RMM-driven cargo theft without breaking logistics operations or delaying shipments.
TruffleNet validates stolen AWS keys, profiles accounts, and abuses Amazon SES to run high-leverage BEC. Therefore, clamp down on access keys, isolate SES to a low-trust account, and alert on first-seen identity actions. Consequently, you deny validation, break pivots, and stop invoice fraud before it lands.
Business email compromise drains budgets with executive spoofing and invoice fraud. This practical Microsoft 365 guide shows nine rules that actually stop BEC: tuned anti-phish and impersonation, Safe Links and Safe Attachments, SPF/DKIM/DMARC, phishing-resistant MFA with Conditional Access, external sender tags, mailbox hygiene, attack simulation, and a short incident playbook.
