How to detect a cyberattack and prevent money theft.

Let’s find out how to detect an attack at each of its stages and minimize the risk, as well as analyze two common scenarios of such attacks — money theft manually using remote control programs and using special malware, a banking trojan: https://amp.gs/j1o57

“We often check retro games. In our company, many developers like to find interesting projects for themselves. They feel nostalgic when they’re studying these projects. But we need to run retro games on something, right? This time we checked a project that helps to run old games on modern hardware”

Full motion video with digital audio on the classic 8-bit game console.

Let’s take an old console from 1983, that only has a handful of kilobytes of memory and mere megahertz of the 8-bit processing power, and make it to play digitized audio: https://amp.gs/jYjMz

How to choose a static analysis tool.

Nowadays, you can find various static analyzers: from free open-source to cross-functional commercial solutions. On the one hand, it’s great — you can choose from many options. On the other hand — you have to perform advanced research to find the right tool for your team: https://amp.gs/jY8CX
