A new attack that uses terrestrial radio signals to hack a wide range of Smart TVs raises an unsettling prospect—the ability of hackers to take complete control of a large number of sets at once without having physical access to any of them.
The proof-of-concept exploit uses a low-cost transmitter to embed malicious commands into a rogue TV signal. That signal is then broadcast to nearby devices. It worked against two fully updated TV models made by Samsung. By exploiting two known security flaws in the Web browsers running in the background, the attack was able to gain highly privileged root access to the TVs. By revising the attack to target similar browser bugs found in other sets, the technique would likely work on a much wider range of TVs.
"Once a hacker has control over the TV of an end user, he can harm the user in a variety of ways," Rafael Scheel, the security consultant who publicly demonstrated the attack, told Ars. "Among many others, the TV could be used to attack further devices in the home network or to spy on the user with the TV's camera and microphone."
Im involved in a project to deploy a SIEM (Security Information Event Management) / SOC (Security Operation Center) for a customer. The current approach is to outsource the services to an external company also called a MSSP (Managed Security Services Provider). We had an interesting chat about the pro con to have an internal or external SOC. The main arguments from the company are:
Often, if not always conceded, the deployment of a SIEM is part of a long list of compliance requirements (from the business or the group the company belongs to).
Here is a small recap of the points we discussed:
And you? What is your point of view? Feel free to share.
