Hacker Reveals Easiest Way to Hijack Privileged Windows User Session Without Password

Hacker Reveals Easiest Way to Hijack Privileged Windows User Session Without Password

March 20, 2017Mohit Kumar
You may be aware of the fact that a local Windows user with system rights and permissions can reset the password for other users, but did you know that a local user can also hijack other users' session, including domain admin/system user, without knowing their passwords? Alexander Korznikov, an Israeli security researcher, has recently demonstrated that a local privileged user can even hijack the session of any logged-in Windows user who has higher privileges without knowing that user's password, using built-in command line tools. This trick works on almost all versions of Windows operating system and does not require any special privileges. Korznikov is himself unable to figure out if it is a Windows feature or a security flaw. The issue discovered by Korznikov is not entirely new, as a French security researcher, namely Benjamin Delpy, detailed a similar user session hijacking technique on his blog some six years ago. Korznikov calls the attack a "privilege

Now you can hijack nearly any drone mid-flight just by using a tiny gadget. Security researcher Jonathan Andersson has devised a small hardware, dubbed Icarus, that can hijack a variety of popular drones mid-flight, allowing attackers to lock the owner out and give them complete control over the device. Andersson, who is the manager of Trend Micro's TippingPoint DVLab division, demonstrated this new hack at this year's PacSec security conference in Tokyo, Japan on Wednesday. Besides Drones, the new gadget has the capability of fully hijacking a wide variety of radio-controlled devices, including helicopters, cars, boats and other remote control gears that run over the most popular wireless transmission control protocol called DSMx. DSMx is a protocol used to facilitate communication between radio controllers and devices, including drones, helicopters, and cars. This is not the first hardware that can hijack drones mid-flight . There are jamming devices available in

Cybercriminals Hijack Router DNS to Distribute Android Banking Trojan

April 16, 2018Swati Khandelwal
Security researchers have been warning about an ongoing malware campaign hijacking Internet routers to distribute Android banking malware that steals users' sensitive information, login credentials and the secret code for two-factor authentication. In order to trick victims into installing the Android malware, dubbed Roaming Mantis , hackers have been hijacking DNS settings on vulnerable and poorly secured routers . DNS hijacking attack allows hackers to intercept traffic, inject rogue ads on web-pages and redirect users to phishing pages designed to trick them into sharing their sensitive information like login credentials, bank account details, and more. Hijacking routers' DNS for a malicious purpose is not new. Previously we reported about widespread DNSChanger and Switcher —both the malware worked by changing the DNS settings of the wireless routers to redirect traffic to malicious websites controlled by attackers.

I have an Android phone with a five different gmail accounts configured in it. But what if any one of them get compromised via phishing, malware or any other way? The Hacker would be able to access my Google account and obviously Google Play Store account too, which allows anyone to install any Android application remotely into my phone without my knowledge and confirmation… What if someone compromises large number of Google accounts and trigger mass installation of a spying or malware app remotely with just one click???? Yes, this was exactly what the National Security Agency (NSA) had done under its widely spread Global surveillance program. A new top-secret document obtained from the former NSA contractor Edward Snowden revealed that the NSA and its closest allies planned to hijack Google and Samsung app stores to infect smartphones with spyware. The operation was launched by the Network Tradecraft Advancement Team, including spy agents from each of the coun

Do you own a blog on WordPress.com website? If Yes, then you should take some extra cautious while signing into your Wordpress account from the next time when connected to public Wi-Fi, because it can be hacked without your knowledge, even if you have enabled two-factor authentication. Yan Zhu , a researcher at the Electronic Frontier Foundation (EFF) noticed that the blogs hosted on WordPress are sending user authentication cookies in plain text, rather than encrypting it. So, it can be easily hijacked by even a Script-Kiddie looking to steal information. HIJACKING  AUTHENTICATION COOKIES When Wordpress users log into their account, WordPress.com servers set a web cookie with name " wordpress_logged_in " into the users’ browser, Yan Zhu explained in a blog post. He noticed that this authentication cookie being sent over clear HTTP, in a very insecure manner. One can grab HTTP cookies from the same Wi-Fi Network by using some specialized tools, such as F

BASHLITE Malware leverages ShellShock Bug to Hijack Devices Running BusyBox

November 17, 2014Swati Khandelwal
Cyber criminals are using new malware variants by exploiting GNU Bash vulnerability referred to as ShellShock ( CVE-2014-6271 ) in order to infect embedded devices running BusyBox software, according to a researcher. A new variant of " Bashlite " malware targeting devices running BusyBox software was spotted by the researchers at Trend Micro shortly after the public disclosure of the ShellShock vulnerability. BusyBox provides set of command line utilities that are specifically designed to run in constrained embedded environments. At compile time, different capabilities can be left out, reducing the size of the binaries, and efforts are made to make them memory efficient. This makes the software an excellent candidate for use in consumer electronics devices, which seem to have been the items of interest in this case. The malware variant, detected as ELF_BASHLITE.A (ELF_FLOODER.W) , when executed on victim's machine, scans compromised networks for device

There are more than 100 Million users who are using Facebook mobile app. Facebook has fixed multiple critical vulnerabilities in its Android based applications that allows hackers to steal access tokens and hijack accounts. Egyptian security researcher Mohamed Ramadan, Security researcher with Attack Secure, has who disclosed  a couple of vulnerabilities in the Facebook Main app and Facebook messenger app and Facebook page's manager application for Android. User’s access token is the key to accessing a Facebook account and according to him, an attacker only needs to send a message that contains an attachment of any type, i.e. Videos, documents, and pictures. Once the victim will click on that file to download, immediately victim's access_token will be stored in the Android's log messages called -  logcat ,  that enables other apps to grab user’s access token and hijack the account.

Proof of Concept : PuttyHijack – Hijack SSH/PuTTY Sessions

October 02, 2011Mohit Kumar
Proof of Concept : PuttyHijack - Hijack SSH/PuTTY Sessions PuttyHijack is a POC tool that injects a dll into the Putty process to hijack an existing, or soon to be created, connection. This can be useful during penetration tests when a windows box that has been compromised is used to SSH/Telnet into other servers. The injected DLL installs hooks and creates a socket in guest operating system for a callback connection that is then used for input/output redirection. PuttyHijack does not kill the current connection, and will cleanly uninject if the socket or process is stopped. Leaves no race for further analysis. How to run/install PuttyHijack Start a nc listener on some fully controlled machine.

I have said it before, and I will say it again — Smart devices are one of the dumbest technologies, so far, when it comes to protecting users' privacy and security. As more and more smart devices are being sold worldwide, consumers should be aware of security and privacy risks associated with the so-called intelligent devices. When it comes to internet-connected devices, smart TVs are the ones that have highly-evolved, giving consumers a lot of options to enjoy streaming, browsing the Internet, gaming, and saving files on the Cloud—technically allowing you to do everything on it as a full-fledged PC. Apparently, in the past few years we have reported how Smart TVs can be used to spy on end users without their explicit consent, how remote hackers can even take full control over a majority of Smart TVs without having any physical access to them, and how flaws in Smart TVs allowed hackers to hijack TV screen . Now most recently, Smart TVs selling under SUPRA brand-name h
