Pendrive Malware | Breaking Cybersecurity News | The Hacker News

Security researchers have discovered a new data-stealing Trojan that makes special use of USB devices in order to spread itself and does not leave any trace of activity on the compromised systems. Dubbed USB Thief ( or Win32/PSW.Stealer.NAI), the malware has the capability of stealthy attacking against air-gapped or isolated computers, warns ESET security firm. The malware author has employed special programs to protect the USB Thief from being reproduced or copied, making it even harder to detect and reverse-engineer. USB Thief has been designed for targeted attacks on computer systems that are isolated from the Internet, according to the ESET malware analyst Tomáš Gardoň. The 'USB Thief' Trojan Malware The USB Thief Trojan malware is stored either as a portable application's plugin source or as a Dynamically Linked Library (DLL) used by the portable application. Since USB devices often store popular applications like Firefox, Notepad++ or TrueCrypt portab...

The bad news is that internal data breaches are on the rise. And one of the biggest culprits? USB devices. In the past few years, there has been many organizations tracking down the loss of sensitive/confidential information due to the usage of USB drives and other mass storage media. Cyber-security breaches and data theft are making more and more IT leaders paranoid about security than ever before. Why are USB devices dangerous? USB devices can hold a lot of information. For example, a 128 GB USB flash drive can store 60,000 photos, 20,000 songs, 100+ videos, and more. Just imagine how many protected corporate files could fit on one drive. Also, the storage capacity of USB devices is only going to increase. USB devices are super portable. Some USB storage devices are the size of a small coin. This makes them very difficult to visually detect when plugged into an open port. USB devices are cheap and easy to find. If you're in the market for a USB storage device, there...

The problem is simple: all breaches start with initial access, and initial access comes down to two primary attack vectors – credentials and devices. This is not news; every report you can find on the threat landscape depicts the same picture.  The solution is more complex. For this article, we'll focus on the device threat vector. The risk they pose is significant, which is why device management tools like Mobile Device Management (MDM) and Endpoint Detection and Response (EDR) are essential components of an organization's security infrastructure. However, relying solely on these tools to manage device risk actually creates a false sense of security. Instead of the blunt tools of device management, organizations are looking for solutions that deliver device trust . Device trust provides a comprehensive, risk-based approach to device security enforcement, closing the large gaps left behind by traditional device management solutions. Here are 5 of those limitations and how to ov...

Once again USB has come up as a major threat to a vast number of users who use USB drives – including USB sticks and keyboards. Security researchers have released a bunch of hacking tools that can be used to convert USB drive into silent malware installer. This vulnerability has come about to be known as " BadUSB ", whose source code has been published by the researchers on the open source code hosting website Github , demanding manufacturers either to beef up protections for USB flash drive firmware and fix the problem or leave hundreds of millions of users vulnerable to the attack. The code released by researchers Adam Caudill and Brandon Wilson has capability to spread itself by hiding in the firmware meant to control the ways in which USB devices connect to computers. The hack utilizes the security flaw in the USB that allows an attacker to insert malicious code into their firmware. But Wait! What this means is that this critical vulnerability is now ava...
