Tag: Backdoor

backdoor is a method, often secret, of bypassing normal authentication in a product, computer system, cryptosystem or algorithm etc. Backdoors are often used for securing unauthorized remote access to a computer, or obtaining access to plaintext in cryptographic systems.

A backdoor may take the form of a hidden part of a program, a separate program (e.g. Back Orifice may subvert the system through a rootkit), or may be a hardware feature. Although normally surreptitiously installed, in some cases backdoors are deliberate and widely known. These kinds of backdoors might have “legitimate” uses such as providing the manufacturer with a way to restore user passwords.

Default passwords can function as backdoors if they are not changed by the user. Some debugging features can also act as backdoors if they are not removed in the release version.

In 1993 the United States government attempted to deploy an encryption system, the Clipper chip, with an explicit backdoor for law enforcement and national security access. The chip was unsuccessful internationally and in business.

WordFence says a fix has landed The folk at WordFence are warning that the WordPress Captcha plugin, popular enough to get around 300,000 installations, should be replaced with the latest official WordPress version (4.4.5).…
At the end of September, Palo Alto released a report on Unit42 activity where they – among other things – talked about PYLOT malware. We have been detecting attacks that have employed the use of this backdoor since at least 2015 and refer to it as Travle.

Coincidentally, KL was recently involved in an investigation of a successful attack where Travle was detected, during which we conducted a deep analysis of this malware.
Involves big hitter Android Studio, APKTool and more Security researchers have found several flaws in the developer tools and environments used by Android programmers.…
Welcome to ransomware in 2017 – the year global enterprises and industrial systems were added to the ever-growing list of victims, and targeted attackers started taking a serious interest in the threat. It was also a year of consistently high attack numbers, but limited innovation.
The accused hacked 3 multinational corporations in pursuit of intellectual property.
Being enthusiastic shoppers just like many other people around the world, at Kaspersky Lab we are, however paranoid enough to look at any Internet of Things (IoT)-device with some concern, even when the price is favorable.
So we randomly took several different connected devices and reviewed their security set up.

Android commercial spyware

Therersquo;s certainly no shortage of commercial spying apps for Android, with most positioned as parental control tools.
In reality, however, these apps barely differ from spyware, with the exception perhaps of the installation method.
Kaspersky Lab's internal investigation found a backdoor Trojan and other malware on the personal computer of the NSA employee who took home agency hacking tools.
In early October, a story was published by the Wall Street Journal alleging Kaspersky Lab software was used to siphon classified data from an NSA employeersquo;s home computer system.

To assist any independent investigators and all the people who have been asking us questions whether those allegations were true, we decided to conduct an internal investigation to attempt to answer a few questions we had related to the article and some others
Looking back at a year like 2017 brings the internal conflict of being a security researcher into full view: on the one hand, each new event is an exciting new research avenue for us, as what were once theoretical problems find palpable expression in reality. On the other hand, as people with a heightened concern for the security posture of users at large, each event is a bigger catastrophe.
OnePlus says it's "looking into" the report.
