2- Ransomware Crooks Demand $70,000 After Hacking San Francisco Transport System
I know we already posted topics about ransomware on our class blogs, but I also found this article interesting as ransomware is becoming a more and more popular form of attack from hackers. This week, Forbes reported that hackers took control of the San Francisco transportation system and demanded 100 Bitcoin, worth roughly $70,000, to release Muni machines from their control. Ransomware should be one of the areas of focus for cyber security. Article is below.
Regarding the Mirai worm attack which deviates my attention with fancy name I think it was actually exploiting one of the type of router which lets this malicious viruses able to get through unsecured ports.It targets unsecured transmission control protocol (TCP) ports on routers. After entering through port 7547, the attack caused routers to download a binary file with the name ‘1’ and execute that file, making the router search for and infect other devices with unsecured TCP ports.
