Microsoft Warns of 'Evolving' LemonDuck Mining Malware Targeting Linux and Windows Machines
Posted: 2021-07-25 21:37:00 Source: http://rss.slashdot.org/~r/Slashdot/slashdotLinuxatom/~3/2SnwkyjIBN0/microsoft-warns-of-evolving-lemonduck-mining-malware-targeting-linux-and-windows-machines
The threat intelligence team for Microsoft's 365 Defender security suite recently focused on an example of "modern mining malware infrastructure," describing how "Anything that can gain access to machines — even so-called commodity malware — can bring in more dangerous threats." Specifically, it offered a case study of LemonDuck. The blog post's title? "When coin miners evolve..." Today, beyond using resources for its traditional bot and mining activities, LemonDuck steals credentials, removes security controls, spreads via emails, moves laterally, and ultimately drops more tools for human-operated activity. LemonDuck's threat to enterprises is also in the fact that it's a cross-platform threat. It's one of a few documented bot malware families that targets Linux systems as well as Windows devices. It uses a wide range of spreading mechanisms — phishing emails, exploits, USB devices, brute force, among others — and it has shown that it can quickly take advantage of news, events, or the release of new exploits to run effective campaigns... Notably, LemonDuck removes other attackers from a compromised device by getting rid of competing malware and preventing any new infections by patching the same vulnerabilities it used to gain access... LemonDuck spreads in a variety of ways, but the two main methods are (1) compromises that are either edge-initiated or facilitated by bot implants moving laterally within an organization, or (2) bot-initiated email campaigns. LemonDuck acts as a loader for many other follow-on activities, but one if its main functions is to spread by compromising other systems. Since its first appearance, the LemonDuck operators have leveraged scans against both Windows and Linux devices for open or weakly authenticated SMB, Exchange, SQL, Hadoop, REDIS, RDP, or other edge devices that might be vulnerable to password spray or application vulnerabilities... Other common methods of infection include movement within the compromised environment, as well as through USB and connected drives. These processes are often kicked off automatically and have occurred consistently throughout the entirety of LemonDuck's operation.

Vector Resize() Function in C++
Posted: 2021-07-25 21:19:22 Source: https://linuxhint.com/vector-resize-function-in-c/
Many built-in functions exist in C++ for doing the different types of tasks in a vector container. The resize() function is one of them. It is used to change the size of the vector. The vector size can be increased or decreased by using this function. The use of the vector resize() function in C++ is explained in this article with examples.
String to Hexadecimal in Python
Posted: 2021-07-25 21:05:51 Source: https://linuxhint.com/string-to-hexadecimal-in-python/
Hexadecimal has a base of 16, and we can represent a string in hexadecimal format using the prefix 0x. The hex () method is very popular because of its easy use. But sometimes, we want to convert the string without using the prefix 0x, so in that case, we can use the bytes encode () method. String to Hexadecimal in Python with examples is explained in this article.

Vector Erase() Function in C++
Posted: 2021-07-25 20:50:50 Source: https://linuxhint.com/vector-erase-function-in-c/
The array is used to store multiple data, and the number of elements of the array can't be changed at the run time. This problem can be solved by using a vector that works like a dynamic array. Different functions exist in the vector class to add and remove an element from the vector. The erase() function is used to remove one or more elements from the vector at the run time that decreases the size of the vector. The use of the vector erase() function in C++ with examples is explained in this article.
Vector Insert() Function in C++
Posted: 2021-07-25 20:48:08 Source: https://linuxhint.com/vector-insert-function-in-c/
The vector is a useful container class of C++ to store the sequence of data that works as a dynamic array. The insert() function is used to add one or more new elements before the specific element of the vector object by mentioning the position of that element. It will increase the size of the vector object dynamically. The use of the vector insert()function in C++ is explained in this article with examples.
Use of Vector Pop_Back() Function in C++
Posted: 2021-07-25 20:46:31 Source: https://linuxhint.com/vector-pop_back-function-in-c/
The size of the vector can be reduced by using different built-in functions of C++. The pop_back() function is one of them. It is used to remove the last element of the vector from the back and reduce the size of the vector by 1. But the last element of the vector is not removed permanently like the erase() function. The use of the vector pop_back()function in C++ is explained in this article with examples.
Vector Push_Back() Function in C++
Posted: 2021-07-25 20:44:33 Source: https://linuxhint.com/vector-push_back-function-in-c/
The push_back() function is one of the ways to insert a new element at the end of the vector that increases the size of the vector by 1. This function is useful when one element is required to add to the vector. If the data type of the vector does not support the value passed by the argument of this function, then an exception will be generated, and no data will be inserted. The use of the vector push_back()function in C++ is explained in this article with examples.

Posted: 2021-07-25 17:03:20 Source: https://linuxhint.com/get-pods-kubectl/
A pod collects one or even more containers with common storage/network assets and a set of instructions for running them. Although pods can accommodate numerous containers, it's best to keep it to a minimum. Kubectl is a command-line tool for running Kubernetes cluster instructions. It accomplishes this by verifying your cluster's Master Node and using API calls to explore a range of management tasks. How to get pods in Kubectl is explained in this article.

When you individually develop a project through any programming language, you're either comfortable with a command-line interface (terminal) or GUI tools. It is good to use a distributed version control system for small and large software projects. Each of the team members will get full access to the complete repository on the local system, and they can work offline. One such versatile software is Git, and a repository handles by Git is known as GitHub. How to Restore Git to Previous State is explained in this article.
