시스코 탈로스 "삼성 스마트싱스 취약점 주시 권고"

[아이뉴스24 성지은 기자] 시스코의 보안연구 조직 탈로스는 삼성 스마트싱스(SmartThings) 허브에서 사용 중인 펌웨어 내부에서 여러 개의 취약점을 발견했다고 27일 발표했다.

삼성 스마트싱스 허브는 스마트 플러그, LED 조명, 온도조절 장치, 카메라 등 스마트홈에 탑재되는 다양한 사물인터넷(IoT) 기기를 제어하고 감시하는 허브 역할을 한다. 사용자들은 스마트폰을 사용해 이러한 기기를 원격으로 제어할 수 있다.

스마트싱스 허브에 사용되는 펌웨어는 리눅스(Linux) 기반으로 설계돼 이더넷·지그비(Zigbee)·지웨이브(Z-Wave)·블루투스 등 서로 다른 다양한 기술을 사용하는 IoT 기기들과 상호 통신한다.

탈로스에 따르면, 공격자는 관련 취약점에 감염된 기기들에 운영체제(OS) 명령, 임의적인 코드 실행 등을 단행할 수 있었다. 민감 정보에 접근하고 스마트홈 내 기기들을 감시·제어해 승인되지 않은 행동들에 활용할 수 있었던 것으로 보인다.

탈로스 측은 "허브 장치는 다양한 환경에서 구축 가능하기 때문에 허브 장치에 대한 공격이 성공할 경우 심각한 피해를 초래할 수 있어 가능한 빠른 업데이트를 권장한다"며 "삼성은 허브 장치에 자동 업데이트를 배포하기 때문에 대부분의 경우 수동 조작이 필요하지 않지만, 업데이트 버전이 실제로 장치에 적용돼 더 이상 취약점에 노출되지 않다는 점을 확인하는 것이 중요하다"고 조언했다.

한편, 탈로스는 사전 조율된 공개 정책에 따라 삼성과 협력으로 관련 이슈를 해결했으며, 펌웨어 업데이트가 제공되도록 지원했다. 삼성은 이번에 발견된 이슈들을 해결하는 펌웨어 업데이트를 배포했다.

Six Tools Used by Hackers to Steal Cryptocurrency: How to Protect Wallets

In the early July, it was reported that Bleeping Computer detected suspicious activity targeted at defrauding 2.3 million Bitcoin wallets, which they found to be under threat of being hacked. The attackers used malware — known as “clipboard hijackers” — which operates in the clipboard and can potentially replace the copied wallet address with one of the attackers. The threat of hacking attacks of this type has been predicted by Kaspersky Lab as early as November of last year, and they did not take long to become reality. For the time being, this is one of the most widespread types of attacks that is aimed at stealing users’ information or money, with the overall estimated share of attacks to individual accounts and wallets being about 20 percent of the total number of malware attacks. And there’s more. On July 12, Cointelegraph published Kaspersky Lab’s report, which stated that criminals were able to steal more than $9 million in Ethere...

Alibaba Opens Robot Restaurant as Automation Expands Around the Globe

https://thespoon.tech/alibaba-opens-robot-restaurant-as-automation-expands-around-the-globe/ Alibaba has opened up a highly automated restaurant in Shanghai, as robots continue to enter eateries around the globe. The Robot.he restaurant in the Hema supermarket uses a series of apps, QR codes, and robots to provide a futuristic dining experience (hat tip to Axios ). The Hema app tells customers where to sit in the restaurant and is used to pay for meals as well as to order more food once seated. Once the food is ready, small pod-like robots scurry out on shiny tracks to deliver it straight to the table. While there is a ton of technology at play here, Hema still relies on humans for much of the work. From the video (see below), staff on-hand helps with the selection of seafood, and there are human cooks making the meals. Alibaba’s news site, Alizila , didn’t say exactly when the restaurant opened, or provide much information regarding future...

BLACK LABEL Secured Automobile Smart Key Solution

Developed by MERCEDES BENZ for the first time 20 years ago, the SmartKey has been very convenient for motorists. However, since this technology has been applied so far, the smart key security has not been upgraded so that even if a simple wireless hacking device is purchased on the market, the password which is exchanged between the car and the smart key is wirelessly captured, the car door is opened, Things are happening in a random way. The biggest problem in smart key security so far is that the identification code exchanged between the smart key and the key is a fixed value and the security is difficult to hack the fixed single code value. However, if a mutual verification system, which is a security solution of BLACK LABEL, is applied to a smart key and a vehicle, it is impossible to access the vehicle even if the identification code value is fixed in a single code, Can be made. This is because the code that has been changed once and then discarded is discarded. ...
