Гадәттә миңа ни өчен ноутбукларымда һәм телефоннарымда яктылык датчикларына стикер эленгән дигән сораулар килә. Кайберәүләр яктылык сенсоры белән камера арасындагы аерманы белмим дип уйлыйлар һәм бу камера түгел дип аңлатырга тырышалар. Алар белмәгән нәрсә шунда ки, тирә-яктагы яктырту сенсорлары була ала…

Mastercardның еллык озын отпускы ярдәмендә (бездә бар 25 көннәр!) I took a two week trip to Egypt earlier this month to visit a place I have always wanted to see: the burial tombs of the ancient pharaohs in the Valley of the Kings. As a security engineer, I could not help looking at these…

Бу хәбәр дустыма җавап булып тора, ул бик кыен базарда киберкуркынычсызлык ролен эзли. Бүгенге көндә бу киң таралган проблема булуын исәпкә алып, I decided to write a post rather than simply leaving a comment. Various statistics from multiple sources suggest that there is a wide gap in cybersecurity roles,…

Минем киберҗинаять дөньясы белән беренче очрашуым берничә ел элек watering hole һөҗүм кампаниясе аша булды.

I promptly contacted the site administrator, who informed me that they had no technical knowledge of the issue. It became apparent that…

DDoS (distributed denial of service) and DoS (denial of service) attacks can be broadly classified into three categories based on the layers of the OSI model they target: network layer (Layer 3), transport layer (Layer 4), and application layer (Layer 7). Layer 3 and Layer 4 attacks are typically less complex–even though that they might…

The web application firewall (WAF) is a security tool used to guard against unwanted access to web applications. It is often a security device that sits on top of a web server and guards against threats from the internet or from beyond the network perimeter. Unlike Layer 3 (Network) and Layer 4 (Transport) firewalls, which…

Canvas fingerprinting, and Zombie cookie trackers are nothing new; however, these methods are improved and have become notoriously effective over the time. Recently, a study revealed that one in every four 10,000 most visited websites on the internet uses canvas fingerprinting to track the visitors with up to 99.9% төгәллек. The tracking attempt to collect…

For many years, I zealously have used Suhosin with any implementations of PHP5 on Apache2 or PHP-FPM Nginx webservers to defend against SQL injection and other common web attacks. In fact, PHP5 was so disastrous, both in terms of its core security, and its functions and modules that I could have never conceived using it…
