Bluetooth bluetooth® technology is widely used in a variety of devices, and will continue to play a key role in the IoT world of IoT. Here are some tips on Bluetooth technology to prepare for reference.Bluetooth bluetooth® Technology was founded in 1994 with the name of a Danish king Harold Bluetoothin 10th century, who unified the current Norwegian, Swedish and Danish regions, Named after him is also a means of connecting the various discrete devices that are now available. So bluetooth® Blueto

it, our goal is to learn how to run this code.
First, download the Red tool chain. Red appears to be too slim and even doubtful about the ability of hundreds of MB of tool chains compared to other programming languages. Can you imagine a tool less than 1MB, containing two compilers (red and Red/system), an interpreter (red)? It's though small, spite.

. Notable development trends include modifying the Protocol to increase the bandwidth of Bluetooth 2.0 + data rate enhanced version-EDR) and planning to bring Bluetooth and ultra-broadband technology to the Alliance recently. The next trend is bound to combine the advantages of the bluetooth wireless lan wpan with the data transmission rate of up to 100 Mbit/s for the UWB system.However, none of these measures can change the following facts: it is tru
With the release of the 4.0 Bluetooth protocol, a growing number of developers have received various development requirements for BLE Bluetooth.And there are many times also need to be compatible with the previous 3.0 version, to the development of people to bring trouble, the author also encountered such problems, accidentally found GetType () This function of the magical.public int GetType () Added in API level 18Get the Bluetooth device type of the remote device.Returns the device type Device

A Cisco router is detected infected with a secret backdoor.
Security company FireEye researchers reported that backdoor programs called SYNful knock were found on 14 Cisco routers in 4 countries. Cisco has confirmed this. The attack does not take advantage of the vulnerability of the product itself, but requires valid management creden。 such as the default password or physical access to the victim's device. Backdoor implants are integrated into modif
Internet Explorer GC Information Leakage
This vulnerability was released by dion Ox a few months ago. Recently, it also won the pwnie award. In the original article, we talked about flash, ff and Other GC engines all adopt conservative mark clearing algorithms and do not mark data or pointers. Therefore, this problem exists. We believe that dion is familiar to everyone, I did not know how to search for flash jit spray. I just checked it. This guy also went to

SlemBunk was first discovered by FireEye. Later, some other security companies also found that the author had the honor to get the sample and analyzed the Trojan horse to find that its design was superb and can be further evolved on this basis. This sample is forged into some other commonly used android applications, deceiving users to input credit card-related sensitive information. Next we will analyz

Cylance and FireEye also use machine learning to apply more advanced detection software. However, they use sandboxes, at least much more than Deep Instinct, and they do not perform real-time monitoring with a low false positive rate.

Today's malware will use some clever technologies to circumvent the traditional signature-based anti-malware detection. Intrusion prevention systems, web page filtering, and Anti-Virus products are no longer able to defend against new categories of attackers. Such new categories combine complex malware with persistent remote access features, the objective is to steal sensitive company data for a long period of time.

Although mainstream websites have announced that they have fixed the heartbleed vulnerability, in fact, for enterprises and ordinary Internet users, the warning of the heartbleed vulnerability is far from being lifted. According to the FireEye report, more than 0.15 billion Android apps downloaded from the Google app store still have the OpenSSL heartbleed vulnerability. Even after Google fixes the Android operating system vulnerability, it cannot eli
