Every week seems to bring news of another data breach, and it's no surprise why: securing sensitive data has become harder than ever. And it's not just because companies are dealing with orders of magnitude more data. Data flows and user roles are constantly shifting, and data is stored across multiple technologies and cloud environments. Not to mention, compliance requirements are only getting stricter and more elaborate.  The problem is that while the data landscape has evolved rapidly, the usual strategies for securing that data are stuck in the past. Gone are the days when data lived in predictable places, with access controlled by a chosen few. Today, practically every department in the business needs to use customer data, and AI adoption means huge datasets, and a constant flux of permissions, use cases, and tools. Security teams are struggling to implement effective strategies for securing sensitive data, and a new crop of tools, called data security platforms, have appear...

A well-known company popular for buying and selling zero-day vulnerabilities is now offering up to $100,000 for providing a working zero-day exploit for bypassing the Flash Player's Heap Isolation mitigation . Few months back, Adobe deployed Heap Isolation in Flash version 18.0.0209 with an aim at making the Use-After-Free (UAF) vulnerabilities more difficult for cybercriminals to exploit. Zerodium is a startup by the infamous French-based company Vupen that Buys and Sells zero-day exploits and vulnerabilities. Zerodium, which describes itself as " the premium zero-day acquisition platform ," recently paid $1 Million bounty to a hacker for submitting a remote browser-based iOS 9.1/9.2b Jailbreak (untethered) Exploit. What is "Isolated Heap" Mitigation Technique? The use-after-free vulnerability is a type of memory corruption flaw that can be exploited by Hackers to execute arbitrary code or even allows full remote code execution capab...
