For now, Chrome security team has only revealed that all four vulnerabilities are use-after-free issues in different components of the web browser, as mentioned below, the critical of which could lead to remote code execution attacks. The use-after-free vulnerability is a class of memory corruption issue that allows corruption or modificat...

EXCLUSIVE — While revealing details of a massive supply chain cyber attack against ASUS customers, Russian security firm Kaspersky last week didn't release the full list all MAC addresses that hackers hardcoded into their malware to surgically target a specific pool of users. Instead, Kaspersky released a dedicated offline tool and launched an online web page where ASUS PC users can search for their MAC addresses to check whether they were in the hit list. However, many believe it is not a convenient way for large enterprises with hundreds of thousands of systems to know if they were targeted or not. List of MAC Addresses Targeted in ASUS Supply Chain Attack To solve this and help other cybersecurity experts continue their hunt for related hacking campaigns, Australian security firm Skylight's CTO Shahar Zini contacted The Hacker News and provided the full list of nearly 583 MAC addresses targeted in the ASUS breach. "If information regarding targets exi...

The team of security researchers—who last month demonstrated how attackers could steal data from air-gapped computers protected inside a Faraday cage—are back with its new research showing how two (or more) air-gapped PCs placed in the same room can covertly exchange data via ultrasonic waves. Air-gapped computers are believed to be the most secure setup wherein the systems remain isolated from the Internet and local networks, requiring physical access to access data via a USB flash drive or other removable media. Dubbed MOSQUITO , the new technique, discovered by a team of researchers at Israel's Ben Gurion University, works by reversing connected speakers (passive speakers, headphones, or earphones) into microphones by exploiting a specific audio chip feature. Two years ago, the same team of researchers demonstrated how attackers could covertly listen to private conversations in your room just by reversing your headphones (connected to the infected computer) into a micr...

WikiLeaks has just published a new set of classified documents linked to another CIA project, dubbed ' Imperial ,' which reveals details of at least three CIA-developed hacking tools and implants designed to target computers running Apple Mac OS X and different flavours of Linux operating systems. If you are a regular reader of THN, you must be aware that this latest revelation by the whistleblower organisation is the part of an ongoing CIA-Vault 7 leaks, marking it as the 18th batch in the series. If you are unaware of the Vault 7 leaks, you can head on to the second of this article for having a brief look on all the leaks at once. Achilles — Tool to Backdoor Mac OS X Disk Images Dubbed Achilles , the hacking tool allows CIA operators to combine malicious Trojan applications with a legitimate Mac OS app into a disk image installer (.DMG) file. The binding tool, the shell script is written in Bash, gives the CIA operators "one or more desired operator specified e...

You need to be more careful next time while leaving your computer unattended at your office, as it cost hackers just $5 and only 30 seconds to hack into any computer. Well-known hardware hacker Samy Kamkar has once again devised a cheap exploit tool, this time that takes just 30 seconds to install a privacy-invading backdoor into your computer, even if it is locked with a strong password. Dubbed PoisonTap , the new exploit tool runs freely available software on a tiny $5/£4 Raspberry Pi Zero microcomputer, which is attached to a USB adapter. The attack works even if the targeted computer is password-protected if a browser is left open in the computer's background. All an attacker need is to plug the nasty device in the target computer and wait. Here's How PoisonTap works: Once plugged into a Windows or Mac computer via USB port, the tiny device starts impersonating a new ethernet connection. Even if the victim's device is connected to a WiFi network, Poi...

Remember Killer USB stick ? A proof-of-concept USB prototype that was designed by a Russian researcher, Dark Purple, last year, to effectively destroy sensitive components of a computer when plugged in. Now, someone has actually created the Killer USB stick that destroys almost anything – such as Laptops, PCs, or televisions – it is plugged into. A Hong Kong-based technology manufacturer is selling a USB thumb drive called USB Kill 2.0 that can fry any unauthorized computer it's plugged into by introducing a power surge via the USB port. It costs $49.95 . How does USB Kill 2.0 work? As the company explains, when plugged in, the USB Kill 2.0 stick rapidly charges its capacitors via the USB power supply, and then discharges – all in a matter of seconds. The USB stick discharges 200 volts DC power over the data lines of the host machine and this charge-and-discharge cycle is repeated several numbers of times in just one second, until the USB Kill stick is removed. ...

Air-gapped computers that are isolated from the Internet and other computers are long considered to be the most secure and safest place for storing data in critical infrastructures such as industrial control systems, financial institutions, and classified military networks. However, these systems have sometimes been targeted in the past, which proves that these isolated systems are not completely secure. Previous techniques of hacking air gap computers include: AirHopper that turns a computer's video card into an FM transmitter to capture keystrokes; BitWhisper that relies on heat exchange between two computer systems to stealthily siphon passwords or security keys; Hacking air-gapped computer using a basic low-end mobile phone with GSM network; and Stealing the secret cryptographic key from an air-gapped computer placed in another room using a Side-Channel Attack. Now, researchers have devised a new method to steal data from an infected computer even if it has no...

Just stop believing everything you see on your screen, as it turns out that even your computer monitor can be hacked. You have seen hackers targeting your computer, smartphone, and tablet, but now, it has been proved that they can even compromise your monitor and turn them against by just changing the pixels displayed on the screen. Although changing pixels is really hard and complicated, a team of security researchers at this year's DEF CON says that it is not impossible. Ang Cui and Jatin Kataria of Red Balloon Security has demonstrated a way to hack directly into the computer that controls monitor to see the pixels displayed on the monitor as well as manipulate the pixels in order to display different images. How to Hack Computer Monitors? According to the researchers, an attacker first needs to gain physical access to the monitor's USB or HDMI port which would then help the attacker access the firmware of the display. The duo said they discovered the hack by rev...

Hacking into computer, networks and websites could easily land you in jail. But what if you could freely test and practice your hacking skills in a legally safe environment? Facebook just open-sourced its Capture The Flag (CTF) platform to encourage students as well as developers to learn about cyber security and secure coding practices. Capture the Flag hacking competitions are conducted at various cyber security events and conferences, including Def Con, in order to highlight the real-world exploits and cyber attacks.

The Raspberry Pi is now gaining attention from malware distributors who want the popular mini-computers to deliver with pre-install malware. The Raspberry Pi Foundation has made a shocking revelation that the charitable foundation has been offered money to install malware onto the Raspberry Pi machines before they were shipped out to users. The Raspberry Pi is an extremely simple computer that looks and feels very basic, but could be built into many geeky projects. Due to the low-cost appeal of the Raspberry Pi, the Foundation has sold over 4 million units. Just Last month, Raspberry Pi unveiled its latest wonder: The Raspberry Pi Zero – a programmable computer that costs just $5 (or £4), may rank as the world's cheapest computer. Last Wednesday, the Foundation tweeted a screenshot of an email in which " business officer"  Linda effectively asked Foundation's director of communications Liz Uptonto to install a suspicious executable file onto Ras...

Can you name which Operating System is most Secure ? ...Windows, Mac, Linux or any particular Linux Distribution? Yes, we get that! It's not an easy thing to pick. Besides Windows, Even the so-called ultra-secure Linux Distros were found to be vulnerable to various critical flaws in past years. Because, almost all Linux Distros use the same Kernel, and the most number of cyber attacks target the Kernel of an operating system. So, It doesn't matter which Linux distribution you use. The kernel is the core part an operating system, which handles all the main activities and enforces the security mechanisms to the entire operating system. Making an Operating System secure requires that vulnerabilities shall not exist in the Kernel, which is the communicating interface between the hardware and the user.  To overcome the above situation, Security Researchers, Mathematicians and Aviation gurus from Boeing and Rockwell Collins joined a team of dedicated NIC...

WhatsApp recently claimed to have hit 900 Million monthly active users , but a dangerous security flaw in the web version of the popular instant messaging app puts up to 200 Million of its users at risk . Yes, the web-based extension of WhatsApp is vulnerable to an exploit that could allow hackers to trick users into downloading malware on their computers in a new and more sophisticated way. WhatsApp made its web client, WhatsApp Web , available to iPhone users just last month, after first rolling out its web-based instant messaging service for Android, Windows and BlackBerry Phone earlier in the year. Similar to Facebook Messenger, WhatsApp Web is an effective way to experience the mobile app in a web browser, allowing you to view all of the conversations you have made with your friends – including images, audio files, videos, GPS location and contact cards – straight on your PCs. However, a security flaw discovered by Check Point's security researcher Kasif...

A security researcher has discovered a critical vulnerability in the latest version of Apple's OS X Yosemite  that could allow anyone to obtain unrestricted root user privileges with the help of code that fits in a tweet. The privilege-escalation vulnerability initially reported on Tuesday by German researcher Stefan Esser , could be exploited by to circumvent security protections and gain full control of Mac computers. The most worrying part is that this critical vulnerability is yet to be fixed by Apple in the latest release of its operating system. This could make it easier for hackers to surreptitiously infect Macs with rootkits and other types of persistent malware. Thanks to an environment variable DYLD_PRINT_TO_FILE Apple added to the code of OS X 10.10 Yosemite. Apple Mac OS X Vulnerability Gives Full Control of your Mac This environment variable specifies where in the file system an operating system component called the OS X dynamic linker dyld ...

There's a new and clever way of hacking into computers, and it can be done cheaply – Using just a radio receiver and a piece of pita bread . Yeah, you heard it right. Security researchers at Tel Aviv University have demonstrated how to extract secret decryption keys from computers by capturing radio emissions of laptop computers . Capturing the radio signals to steal data from a computer system is nothing new. But the process required expensive, bulky lab equipment to accomplish. However, the Israeli-based researchers team managed to do it with cheap consumer-grade components as well as small enough to hide inside a piece of pita bread. Using cheap equipment, the team of researchers, including Daniel Genkin, Lev Pachmanov, Itamar Pipman and Eran Tromer , was able to capture keystrokes, applications running on a computer system, and encryption keys. How the method works? The idea is simple, as different computer operations, such as playing some game o...
