In recent years, malicious code has caused significant damage to computer systems worldwide. For example, the “WannaCry” ransomware worm, released in May 2017, severely damaged thousands of computers by encrypting data. In just one day, the “WannaCry” virus infected 150 countries and 230,000 systems. According to statistics from the FBI, ransomware is the fastest-growing malware … Read more
1Introduction Online debugging (OCD, On-Chip Debugging) interfaces provide chip-level control over target devices, serving as a primary means for engineers, researchers, and hackers to extract firmware code or data, modify memory contents, or change device operations. If you are familiar with hardware circuits or embedded systems, you certainly know that JTAG (Joint Test Action Group) … Read more
In a world filled with PPT presentations, some phenomena are quite interesting. For example, maybe your girlfriend has never heard of what an embedded system is, but she definitely knows what the Internet of Things (IoT) is; even if she doesn’t know that “the Internet has no privacy,” she surely knows that “the most critical … Read more
Researchers from Kaspersky Lab periodically analyze the popular security technologies in the cybersecurity market. This time, they decided to study what security technologies operating system developers provide for embedded systems (in other words, the Internet of Things). Our main interest lies in how these operating systems address issues related to cybersecurity. Note that during the … Read more
