When you point a subdomain (like blog.yourcompany.com) to a cloud service and then close that service, the DNS record is left dangling. An attacker can seize your subdomain by claiming that service in their own name. This vulnerability is used for phishing on your domain, cookie theft and brand abuse. We explain how subdomain takeover happens, its effects and how to prevent it, with sources.
Read moreWhen an API key, database password or secret token stays embedded in code or accidentally leaks to GitHub, a frontend bundle or a backup, attackers find it within minutes. The result can be your cloud account being taken over, a data breach and high bills. We explain how leaked keys are found, their effects, and how to prevent them with secrets management, with sources.
Read moreIf your domain has no DMARC record, an attacker can send fake email in your name, from your domain. This vulnerability is used to phish your customers, commit invoice fraud and destroy your brand reputation. We explain how this vulnerability works, its effects, how to test whether your domain is exposed, and how to close it with SPF, DKIM and DMARC, with sources.
Read moreIf you run an e-commerce site, corporate website or web application in Istanbul, your site's security is both your reputation and your KVKK obligation. The most common web attacks, why penetration testing is needed, WAF and basic hardening, KVKK compliance, and choosing the right security service in Istanbul. A sourced, actionable guide.
Read moreiCloud is your phone's most important backup, but just as much a valuable target. The way to protect your Apple ID and iCloud data is a strong password, two factor authentication, a recovery key, and correctly using Advanced Data Protection (ADP), which provides end to end encryption. We explain what is encrypted, what is not protected, and how to secure your account, with sources.
Read moreData recovery is a last resort, the real work is protecting data before you lose it. The way to protect the photos, messages and accounts on your phone is correct backup, full disk encryption, a strong screen lock, theft and remote wipe measures, and managing app permissions. A step by step, sourced protection guide for Android and iPhone.
Read moreFor companies operating in Ankara, KVKK compliance is now mandatory. Who needs a VERBIS registration, which policies and documents must be prepared, how to build a data inventory, how to manage employee notices and explicit consent, the 72-hour breach rule and administrative fines. A step-by-step, sourced KVKK compliance and audit guide for Ankara-based businesses.
Read moreThree names stand out in mobile forensics: Cellebrite UFED, GrayKey and Oxygen Forensic Detective. Which is strong at unlocking, which at extraction breadth, which at analysis? An honest, sourced comparison of the difference between logical, file-system and physical extraction, why device/version support constantly changes, and the reality that these tools are for authorized use only.
Read moreThe foundation of professional data recovery is not copying files from a failing disk but taking a bit-by-bit copy of the entire surface. We explain what a raw image is, why it differs from copying files, how ddrescue and hardware imagers work, bad-sector mapping, what carving (recovering data without a file system) is, and how hash verification preserves forensic integrity, with sources.
Read morePC-3000 is the reference hardware of professional data recovery, but it is not a single device, it is a product family: PC-3000 Express, PC-3000 UDMA, PC-3000 Portable III and the SSD module. We explain which model is for which failure and lab scenario, its firmware service-area repair and bit-by-bit imaging capabilities, and why it needs hardware rather than software, with sources.
Read moreThe phone is physically intact but no one knows the screen passcode, or the device is fully encrypted. This is very different from a cracked screen or a water-damaged phone: the data is not lost, it is locked behind encryption. We honestly explain modern Android file-based encryption (FBE), the iPhone Secure Enclave, the limits of passcode cracking and what forensic unlock tools like Cellebrite can and cannot do, with sources.
Read moreAn unauthorized penetration test is a crime in Turkey. A test done without written authorization can fall under TCK 243, 244 and 245. We explain the legal framework (TCK, CMK 134, KVKK Article 12), the indispensable clauses of a pentest contract and Rules of Engagement, the PTES Permission to Test document and the get-out-of-jail letter, with sources, as a practical guide.
