Information security and privacy are consistently hot topics after Edward Snowden revelations of NSA's global surveillance that brought the world's attention towards data protection and encryption as never before. Moreover, just days after Windows 10 's successful launch last summer, we saw various default settings in the Microsoft's newest OS that compromise users' privacy , making a large number of geeks, as well as regular users, migrate to Linux. However, the problem is that majority of users are not friendly to the Linux environment. They don't know how to configure their machine with right privacy and security settings, which makes them still open to hacking and surveillance. However, this gaping hole can be filled with a  Debian-based  Security-focused Linux operating system called Subgraph OS: A key solution to your Privacy Fear. Subgraph OS is a feather weighted Linux flavor that aims to combat hacking attacks easier, even on fai...

Finally, it's happening. Microsoft has built its own custom Linux kernel to power " Azure Sphere ," a newly launched technology that aims to better secure billions of " Internet of things " devices by combining the custom Linux kernel with new chip design, and its cloud security service. Project Azure Sphere focuses on protecting microcontroller-based IoT devices, including smart appliances, connected toys, and other smart gadgets, Microsoft announced during the security-focused RSA Conference in San Francisco Monday. It is basically a security package consists of three main components: Azure Sphere-certified microcontrollers (MCUs) Azure Sphere OS Azure Sphere Security Service "Azure Sphere provides security that starts in the hardware and extends to the cloud, delivering holistic security that protects, detects, and responds to threats—so they're always prepared," Microsoft said. Internet of Things (IoT) devices are 'ridicu...

If you are using the Internet, there are the possibilities that you are open to attack. The Transmission Control Protocol (TCP) implementation in all Linux systems deployed since 2012 ( version 3.6 and above of the Linux kernel ) poses a serious threat to Internet users, whether or not they use Linux directly. This issue is troubling because Linux is used widely across the Internet, from web servers to Android smartphones, tablets, and smart TVs. Researchers have uncovered a serious Internet flaw, which if exploited, could allow attackers to terminate or inject malware into unencrypted communication between any two vulnerable machines on the Internet. The vulnerability could also be used to forcefully terminate HTTPS encrypted connections and downgrade the privacy of secure connections, as well as also threatens anonymity of Tor users by routing them to certain malicious relays. The flaw actually resides in the design and implementation of the Request for Comments: 5961 ( RF...

Security researchers working for F-Secure have found a web exploit that detects the operating system of the computer and drops a different trojan to match.The attack was first seen on a Columbian transport website which had been hacked by a third party. This malware is known as GetShell.A and requires users to approve a Java applet installation. It detects if you're running Windows, Mac OS X, or Linux, and then downloads the corresponding malware for your platform. The malicious files developed for each type of OS connect to the same Command & Control server that F-Secure has localized at IP address 186.87.69.249. Karmina Aquino, a senior analyst with F-Secure said " All three files for the three different platforms behave the same way. They all connect to 186.87.69.249 to get additional code to execute. The ports are 8080, 8081, and 8082 for OSX, Linux and Windows, respectively ." On upcoming 29th July 2012 Security Researchers  Sina Hatef Matbue and Arash Shirk...

Cybersecurity researchers have disclosed vulnerabilities in select model webcams from Lenovo that could turn them into BadUSB attack devices. "This allows remote attackers to inject keystrokes covertly and launch attacks independent of the host operating system," Eclypsium researchers Paul Asadoorian, Mickey Shkatov, and Jesse Michael said in a report shared with The Hacker News. The vulnerabilities have been codenamed BadCam (aka CVE-2025-4371 ) by the firmware security company. The findings were presented at the DEF CON 33 security conference today. The development likely marks the first time it has been demonstrated that threat actors who gain control of a Linux-based USB peripheral that's already attached to a computer can weaponize it for malicious intent. In a hypothetical attack scenario, an adversary can take advantage of the vulnerability to send a victim a backdoored webcam, or attach it to a computer if they are able to secure physical access, and remot...

As Millions of Hackers, Spammers and Scammers are after your sensitive online data, you can't really expect your passwords to stay secure forever, even if you are using long passwords. Most of us might be worried about losing our passwords as we keep signing up for online services. However, Google is equally concerned about your online security and wants to help you protect your most sensitive data in a most smarter way. Google has now made what has to be one of the smallest computers ever — Project Vault. That's a really catching name announced on the second day of the annual Google I/O developers conference on Friday. Project Vault, designed by Google's ATAP (Advanced Technology and Projects) group, is a secure computer entirely packed onto a microSD card that can be plugged into any system whether it's a desktop or a mobile phone. The vault is technically a computer though it is not for regular computing. Rather it is a new and secure way to com...

Google is bringing a host of new features to its Android 4.2 Jelly Bean operating system designed to increase productivity, creativity and peace of mind and some very promising security improvements including: client side malware protection, Security Enhanced Linux, and always-on VPN . Most important Security Improvements in Android 4.2 is that it now includes a service based on Bouncer that works with all apps, not just those on Google Play. For example, it can check the apps you download on the Amazon App Store, or from 3rd Party sites. Whenever user will install any app from a different source than the official market, and will scan it for any malicious code that may prove potentially harmful for your device. Other than this, Users can now control how much data apps can access and share. This is made even more secure by something called VPN lockdown that can limit the amount of information sent over a connection that may not be secure or that is shared rather ...

A new Firefox add-on called "Firesheep," developed by Seattle-based freelance Web application developer Eric Butler, enables almost anyone to scan a Wi-Fi network and hijack others' access to popular services like Facebook, Twitter, and others. Butler unveiled Firesheep at the ToorCon security conference in San Diego, which occurred from October 22-24. Butler explained that he developed Firesheep to highlight the risks associated with accessing unencrypted websites via public Wi-Fi spots. While many sites secure user log-ins with HTTPS or SSL, they often do not encrypt the rest of the traffic. "This leaves the cookie, and the user, vulnerable," Butler stated in a blog post. "On an open wireless network, cookies are basically shouted through the air, making these attacks extremely easy." Once a hacker obtains a user's cookie, they can perform any action that the user can on the website. Firesheep can hijack sessions on several major sites, includ...

A newly disclosed vulnerability affecting Intel processors could be abused by an adversary to gain access to sensitive information stored within enclaves and even run arbitrary code on vulnerable systems. The vulnerability ( CVE-2021-0186 , CVSS score: 8.2) was discovered by a group of academics from ETH Zurich, the National University of Singapore, and the Chinese National University of Defense Technology in early May 2021, who used it to stage a confidential data disclosure attack called " SmashEx " that can corrupt private data housed in the enclave and break its integrity. Introduced with Intel's Skylake processors, SGX (short for Software Guard eXtensions) allows developers to run selected application modules in a completely isolated secure compartment of memory, called an enclave or a Trusted Execution Environment (TEE), which is designed to be protected from processes running at higher privilege levels like the operating system. SGX ensures that data is secure ...

Researchers have discovered a severe vulnerability in Cisco products that could allow attackers to implant persistent backdoor on wide range devices used in enterprises and government networks, including routers, switches, and firewalls. Dubbed Thrangrycat or 😾😾😾, the vulnerability, discovered by researchers from the security firm Red Balloon and identified as CVE-2019-1649, affects multiple Cisco products that support Trust Anchor module (TAm). Trust Anchor module (TAm) is a hardware-based Secure Boot functionality implemented in almost all of Cisco enterprise devices since 2013 that ensures the firmware running on hardware platforms is authentic and unmodified. However, researchers found a series of hardware design flaws that could allow an authenticated attacker to make the persistent modification to the Trust Anchor module via FPGA bitstream modification and load the malicious bootloader. "An attacker with root privileges on the device can modify the contents of...

A leading provider of advanced threat, security and compliance solutions, Tripwire , has announced that Craig Young , a security researcher from its Vulnerability and Exposure Research Team (VERT) , is working on a paper about SSL vulnerabilities that will be presented at DEF CON 22 Wireless Village . There are thousands of websites over Internet that contain serious mistakes in the way that Secure Sockets Layer and Transport Layer Security (SSL/TLS) is implemented, leaving them vulnerable to man-in-the-middle (MitM) attacks that could compromise sensitive user data such as banking credentials, credit card numbers and other information. MitM attack is one of the common and favorite techniques of attackers used to intercept wireless data traffic. Cyber criminals could able to intercept sensitive user data, including credit card numbers, PayPal credentials and social network credentials as well. Young has unearthed various situations where poor SSL implementations in co...

A group of academics from the University of California and Tsinghua University has uncovered a series of critical security flaws that could lead to a revival of DNS cache poisoning attacks. Dubbed " SAD DNS attack " (short for Side-channel AttackeD DNS), the technique makes it possible for a malicious actor to carry out an off-path attack, rerouting any traffic originally destined to a specific domain to a server under their control, thereby allowing them to eavesdrop and tamper with the communications. "This represents an important milestone — the first weaponizable network side channel attack that has serious security impacts," the researchers said. "The attack allows an off-path attacker to inject a malicious DNS record into a DNS cache." Tracked as CVE-2020-25705, the findings were presented at the ACM Conference on Computer, and Communications Security (CCS '20) held this week. The flaw affects operating systems Linux 3.18-5.10, Windows Serv...
