Denial-of-Service and Man-in-the-middle vulnerabilities found in Smart scale IoT device

An IoT device analyzed by researchers was found to have four security flaws that could allow attackers to perform denial of service (DoS) and man-in-the-middle(MITM) attacks.
The device’s associated mobile apps on iOS and Android also had other privacy issues.

A string of security flaws was found in an IoT device that monitored users’ weight and related body factors. The device, known as Smart Scale PW 5653 by AEG is prone to adversarial situations such as DoS and MITM attacks. On Monday, security firm Checkmarx discovered these security loopholes in their analysis of the device. In addition, mobile apps associated with Smart Scale also had privacy issues.

As per the report by David Sopas of Checkmarx, vulnerabilities were mainly related to Bluetooth security. Attackers could exploit the Bluetooth Low Energy(BLE) technology in Smart Scale and conduct DoS as well as change internal settings in the device. The report classified the four vulnerabilities as ‘medium’ severity.

Exploits

After finding the security issues, Checkmarx team created an exploit that disables the device itself.

“We wrote a small proof-of-concept exploit (using pygatt python lib) to replicate it. It connects to the device, sleeps for 5 seconds (the device enters standby mode meanwhile), sends the request, and crashes the smart scale,” the researchers said, explaining the exploit functionality.

Moreover, privacy settings and the name of the device can also be changed with a tool known as GATTTool.

Coming to Smart Scale mobile apps, some of the permissions required by them are not relevant. For example, the Android app requests location to be switched on and access for device storage to function properly. Both of these are intrusive and do not clearly fit into the context of an IoT weighing scale. On the other hand, the iOS app sent device information to a server in China without the user’s knowledge.

Checkmarx has informed Smart Scale’s maker AEG of these problems. However, they are yet to respond with a fix.

Tr0ll 1.0 – Vulnhub CTF Challenge Walkthrough

Tr0ll 1.0 is an intentionally vulnerable machine, which is more of a CTF like type than real world scenario. Nevertheless, this machine has its own difficulties and you can learn some new stuff from it. So, let’s start. Enumeration Phase Let’s first run netdiscover to find the IP of our machine. netdiscover -r 192.168.1.1/24 After that, we run our typical nmap scan to see the open ports in the machine. nmap -A -sS -Pn -vv [target] Great we see many interesting stuff here. First of all, there is an open FTP port and we can connect to it with anonymous access . Also there is an open http port, we will run a nikto scan for it. The ssh port will be valuable later. From the nikto scan we got an interesting /secret/ folder. When we get inside, we can understand why the machine got this name. Nothing interesting here, as you can see. we got trolled Let’s connect to the ftp server. When we get asked for the username we type ‘ anonymous ‘ and we l

Uber fined $1.1 million by UK and Dutch regulators over 2016 data breach

British and Dutch data protection regulators Tuesday hit the ride-sharing company Uber with a total fine of $1,170,892 (~ 1.1 million) for failing to protect its customers’ personal information during a 2016 cyber attack involving millions of users. Late last year, Uber unveiled that the company had suffered a massive data breach in October 2016, exposing names, email addresses and phone numbers of 57 million Uber riders and drivers along with driving license numbers of around 600,000 drivers. Besides this, it was also reported that instead of disclosing the breach at the time, the company paid $100,000 in ransom to the two hackers with access to the stolen data in exchange for keeping the incident secret and deleting the information. Today Britain’s Information Commissioner’s Office (ICO) fined Uber 385,000 pounds ($491,102), while the Dutch Data Protection Authority (Dutch DPA) levied a 600,000 euro ($679,790) penalty on Uber for failing to protect the personal informa
