Unpatched Bug Let Attackers Bypass Windows Lock Screen On RDP Sessions

Unpatched Bug Let Attackers Bypass Windows Lock Screen On RDP Sessions

Jun 04, 2019
A security researcher today revealed details of a newly unpatched vulnerability in Microsoft Windows Remote Desktop Protocol (RDP). Tracked as CVE-2019-9510 , the reported vulnerability could allow client-side attackers to bypass the lock screen on remote desktop (RD) sessions. Discovered by Joe Tammariello of Carnegie Mellon University Software Engineering Institute (SEI), the flaw exists when Microsoft Windows Remote Desktop feature requires clients to authenticate with Network Level Authentication (NLA), a feature that Microsoft recently recommended as a workaround against the critical BlueKeep RDP vulnerability . According to Will Dormann, a vulnerability analyst at the CERT/CC, if a network anomaly triggers a temporary RDP disconnect while a client was already connected to the server but the login screen is locked, then "upon reconnection the RDP session will be restored to an unlocked state, regardless of how the remote system was left." "Starting with W
Firefox Web Browser Now Blocks Third-Party Tracking Cookies By Default

Firefox Web Browser Now Blocks Third-Party Tracking Cookies By Default

Jun 04, 2019
As promised, Mozilla has finally enabled "Enhanced Tracking Protection" feature on its Firefox browser by default, which from now onwards would automatically block all third-party tracking cookies that allow advertisers and websites to track you across the web. Tracking cookies, also known as third-party cookies, allows advertisers to monitor your online behavior and interests, using which they display relevant advertisements, content, and promotions on the websites you visit. Which makes sense as no one likes to waste time in watching advertisements and offers that are not of one's interest. However, since tracking cookies gather way more information without requiring users' explicit permissions and there is no control over how companies would use it, the technique also poses a massive threat to users' online privacy. To limit this extensive tracking, Mozilla included the "Enhanced Tracking Protection" option as an experimental feature in Octo
Making Sense of Operational Technology Attacks: The Past, Present, and Future

Making Sense of Operational Technology Attacks: The Past, Present, and Future

Mar 21, 2024Operational Technology / SCADA Security
When you read reports about cyber-attacks affecting operational technology (OT), it's easy to get caught up in the hype and assume every single one is sophisticated. But are OT environments all over the world really besieged by a constant barrage of complex cyber-attacks? Answering that would require breaking down the different types of OT cyber-attacks and then looking back on all the historical attacks to see how those types compare.  The Types of OT Cyber-Attacks Over the past few decades, there has been a growing awareness of the need for improved cybersecurity practices in IT's lesser-known counterpart, OT. In fact, the lines of what constitutes a cyber-attack on OT have never been well defined, and if anything, they have further blurred over time. Therefore, we'd like to begin this post with a discussion around the ways in which cyber-attacks can either target or just simply impact OT, and why it might be important for us to make the distinction going forward.

Apple Launches Privacy-Focused 'Sign in with Apple ID' Feature at WWDC 2019

Apple Launches Privacy-Focused 'Sign in with Apple ID' Feature at WWDC 2019

Jun 03, 2019
Just like 'login with Google,' 'login with Facebook,' Twitter, LinkedIn or any other social media site, you would now be able to quickly sign-up and log into third-party websites and apps using your Apple ID. What's the difference? Well, Apple claims that signing-in with Apple ID would protect users' privacy by not disclosing their actual email addresses to the 3rd-party services and also limiting personal information to the minimum necessary data. While announcing 'Sign in with Apple' today at WWDC, the company revealed that the feature has been designed to randomly generate a new unique email address for each different service a user sign-up with, and will forward all emails to your primary email ID, internally. "It [randomly generate emails] is a smart jab against spam: Not only will you be able to turn off spammy email more easily, but you'll also be able to see who exactly is sharing and selling your email widely when that random a

macOS 0-Day Flaw Lets Hackers Bypass Security Features With Synthetic Clicks

macOS 0-Day Flaw Lets Hackers Bypass Security Features With Synthetic Clicks

Jun 03, 2019
A security researcher who last year bypassed Apple 's then-newly introduced macOS privacy feature has once again found a new way to bypass security warnings by performing 'Synthetic Clicks' on behalf of users without requiring their interaction. Last June, Apple introduced a core security feature in MacOS that made it mandatory for all applications to take permission ("allow" or "deny") from users before accessing sensitive data or components on the system, including the device camera or microphone, location data, messages, and browsing history. For those unaware, 'Synthetic Clicks' are programmatic and invisible mouse clicks that are generated by a software program rather than a human. MacOS itself has built-in functionality for synthetic clicks, but as an accessibility feature for disabled people to interact with the system interface in non-traditional ways. So, the feature is only available for Apple-approved apps, preventing ma
SUPRA Smart TV Flaw Lets Attackers Hijack Screens With Any Video

SUPRA Smart TV Flaw Lets Attackers Hijack Screens With Any Video

Jun 03, 2019
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

Hackers Stole Customers' Credit Cards from 103 Checkers and Rally's Restaurants

May 31, 2019
If you have swiped your payment card at the popular Checkers and Rally's drive-through restaurant chains in past 2-3 years, you should immediately request your bank to block your card and notify it if you notice any suspicious transaction. Checkers, one of the largest drive-through restaurant chains in the United States, disclosed a massive long-running data breach yesterday that affected an unknown number of customers at 103 of its Checkers and Rally's locations—nearly 15% of its restaurants. The impacted restaurants [ name, addresses and exposure dates ] reside in 20 states, including Florida, California, Michigan, New York, Nevada, New Jersey, Florida, Georgia, Ohio, Illinois, Indiana, Delaware, Kentucky, Louisiana, Alabama, North Carolina, Pennsylvania, Tennessee, West Virginia and Virginia. After becoming aware of a "data security issue involving malware" at some Checkers and Rally's locations, the company launched an extensive investigation which r

Hackers Infect 50,000 MS-SQL and PHPMyAdmin Servers with Rootkit Malware

May 29, 2019
Cyber Security researchers at Guardicore Labs today published a detailed report on a widespread cryptojacking campaign attacking Windows MS-SQL and PHPMyAdmin servers worldwide. Dubbed Nansh0u , the malicious campaign is reportedly being carried out by an APT-style Chinese hacking group who has already infected nearly 50,000 servers and are installing a sophisticated kernel-mode rootkit on compromised systems to prevent the malware from being terminated. The campaign, which dates back to February 26 but was first detected in early-April, has been found delivering 20 different payload versions hosted on various hosting providers. The attack relies on the brute-forcing technique after finding publicly accessible Windows MS-SQL and PHPMyAdmin servers using a simple port scanner. Upon successful login authentication with administrative privileges, attackers execute a sequence of MS-SQL commands on the compromised system to download malicious payload from a remote file server and
