Dear Readers,
Let's discuss the critical issue of ransomware attacks further. According to our Advisory Board member, Paulo Pereira, this topic is highly disruptive to our daily lives. Just recalling the attack in LA is concerning. In September 2022, a ransomware attack and data leak led to compromised assessment records, driver's license numbers, and Social Security numbers of around 2,000 students, including 60 currently enrolled. We do not have many places here to multiply such examples, but there are uncountable cases like this one. Such attacks are harmful not only to individuals, but also to companies and organizations. So let’s see what you can find this time in the issue.
Best regards,
Ewa & eForensics Team

AI Powered Ransomware Protection
Kate Libby
AI refers to the development of computer systems that can perform tasks that typically require human intelligence, such as learning, reasoning, and problem-solving. These computer systems are designed to mimic human cognitive abilities, including perception, recognition, and decision-making. Some recent and very well-known examples are Open AI’s ChatGPT and Microsoft’s AI which has been integrated into Bing. If you have used any of these platforms, then you have probably experienced some scary capabilities and shortcomings.
