  • New software security tool to detect bugs in OS

    The Universal Serial Bus (USB) connects external devices to a host. This interface exposes the OS kernels and device drivers to attacks by malicious devices.

    To help detect such vulnerabilities, EPFL researchers have come up with a new security tool called USBFuzz to identify vulnerabilities in the USB driver stacks of widely used operating systems, including Linux, Windows, and macOS.

  • Github uncovers malicious ‘Octopus Scanner’ targeting developers

    The malware is called the Octopus Scanner, and it targets Apache NetBeans, which is an integrated development environment used to write Java software. In its write-up of the attack, the GitHub Security Labs team explains how the malware lurks in source code repositories uploaded to its site, activating when a developer downloads an infected repository and uses it to create a software program.

  • Joomla Team Disclosed Data Breach Occurred Last Week

    Joomla! is one of the biggest CMS in the World, to be specific, it is the 3rd most popular after WordPress and Drupal. Being that big in the industry, even a tiny error can cause millions of users worldwide. Just a few days back, the Joomla! team announced a data breach that occurred accidentally last week.

    Thankfully, the breach does not affect millions but 2,700 users who registered on JRD, Joomla Resources Directory. The incident happened last week when a member of JRD left a full unencrypted backup of JRD on AWS S3 server.

    [...]

    Most of the users’ information involved in the breach is already public except the IP address and hashed passwords. If anyone found the backup and successfully unhashed the passwords, he can use those passwords on other websites like Gmail, Microsoft, Facebook, etc. to access them. If you are affected by the breach, used the same passwords on Gmail, Facebook, etc. as on JRD platform, change your passwords immediately.

  • KeePassXC review

    KeePassXC appeals to Linux users who want to handle their own password management offline, but the added effort involved and lack of built-in password sync will frustrate casual users.

  • Career Choice Tip: Cybercrime is Mostly Boring [iophk: Windows TCO]

    For example, running an effective booter service requires a substantial amount of administrative work and maintenance, much of which involves constantly scanning for, commandeering and managing large collections of remote systems that can be used to amplify online attacks.

  • Find the coefficients of the Quadratic Equation of the given two roots with Python

    In this example, you are expected to find the coefficients of the quadratic equation of the given two roots (x1 and x2) with a python function. The Quadratic Equation looks like this ax^2 + bx + c = 0. Our mission is to find the coefficients of the equations which is a, b, and c. The return type from the function is a Vector containing coefficients of the equations in the order (a, b, c). Since there are infinitely many solutions to this problem, we fix a = 1. Below is the method to find the return Vector.

  • 10 most useful Python Dictionary Methods

    Dictionary is used in python to store multiple data with key-value pairs. It works like an associative array of other programming languages. The curly ({}) brackets are used to define a dictionary and the key-value is defined by the colon(:). The content of the key and value can be numeric or string. Python has many built-in methods to do different types of tasks on the dictionary data such as add, update, delete, search, count, etc. 10 most useful dictionary methods of python are explained in this article.

  • 10 most useful Python String Methods

    The string data is the characters of an array that contains one or more characters as value for any programming language. All printable characters such as alphabets, numbers, special characters, etc. are commonly used in the string data. ASCII code and Unicode are mainly used for converting any character to a number that the computer can understand. Python uses Unicode characters for string data. We need to perform different types of tasks based on the programming purpose on the string data such as searching the particular character or characters, capitalizing the first character, making all characters uppercase, etc. Python has many built-in string methods to do these types of tasks very easily. The 10 most useful python string methods are explained in this article.
