LockBit
LockBit is a cybercriminal group proposing ransomware as a service (RaaS). Software developed by the group (also called ransomware) enables malicious actors who are willing to pay for using it to carry out attacks in two tactics where they not only encrypt the victim's data and demand payment of a ransom, but also threaten to leak it publicly if their demands are not met. According to a joint statement by various government agencies, LockBit was the world's most prolific ransomware in 2022. It was estimated in early 2023 to be responsible for 44% of all ransomware incidents globally. In the United States between January 2020 and May 2023, LockBit was used in approximately 1,700 ransomware attacks, with US$91 million paid in ransom to hackers. Government agencies did not formally attribute the group to any nation-state. Software with the name "LockBit" appeared on a Russian-language based cybercrime forum in January 2020. The group is financially motivated. However, in an interv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ransomware As A Service
Ransomware as a service (RaaS) is a cybercrime business model where ransomware operators write software and affiliates pay to launch attacks using said software. Affiliates do not need to have technical skills of their own but rely on the technical skills of the operators. The "ransomware as a service" model is a criminal variation of the "software as a service" business model. This model allows small threat attackers to gain access to sophisticated ransomware tools at lower costs, also lowering the threshold of entry into cybercrime and complicating defenses against hacking. Revenue models Affiliates can choose from different revenue models, including monthly subscriptions, affiliate programs, one-time license fees, and pure profit sharing. The most advanced RaaS operators provide portals that allow their subscribers to track the status of infections, payments, and encrypted files. This level of support and functionality is similar to legitimate SaaS products. A common profit sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ransomware
Ransomware is a type of malware that Encryption, encrypts the victim's personal data until a ransom is paid. Difficult-to-trace Digital currency, digital currencies such as paysafecard or Bitcoin and other cryptocurrency, cryptocurrencies are commonly used for the ransoms, making tracing and prosecuting the perpetrators difficult. Sometimes the original files can be retrieved without paying the ransom due to implementation mistakes, leaked cryptographic keys or a complete lack of encryption in the ransomware. Ransomware attacks are typically carried out using a Trojan horse (computing), Trojan disguised as a legitimate file that the user is tricked into downloading or opening when it arrives as an email attachment. However, one high-profile example, the WannaCry worm, traveled automatically between computers without user interaction. Starting as early as 1989 with the first documented ransomware known as the AIDS (Trojan horse), AIDS trojan, the use of ransomware scams grew inter ...

Cybercriminal
Cybercrime encompasses a wide range of criminal activities that are carried out using digital devices and/or networks. It has been variously defined as "a crime committed on a computer network, especially the Internet"; Cybercriminals may exploit vulnerabilities in computer systems and networks to gain unauthorized access, steal sensitive information, disrupt services, and cause financial or reputational harm to individuals, organizations, and governments. In 2000, the tenth United Nations Congress on the Prevention of Crime and the Treatment of Offenders classified cyber crimes into five categories: unauthorized access, damage to computer data or programs, sabotage to hinder the functioning of a computer system or network, unauthorized interception of data within a system or network, and computer espionage. Internationally, both state and non-state actors engage in cybercrimes, including espionage, financial theft, and other cross-border crimes. Cybercrimes crossing internatio ...

PowerShell
PowerShell is a shell program developed by Microsoft for task automation and configuration management. As is typical for a shell, it provides a command-line interpreter for interactive use and a script interpreter for automation via a language defined for it. Originally only for Windows, known as Windows PowerShell, it was made open-source and cross-platform on August 18, 2016, with the introduction of PowerShell Core. The former is built on the .NET Framework; the latter on .NET (previously .NET Core). PowerShell is bundled with current versions of Windows and can be installed on macOS and Linux. Since Windows 10 build 14971, PowerShell replaced Command Prompt as the default command shell exposed by File Explorer. In PowerShell, administrative tasks are generally performed via ''cmdlets'' (pronounced ''command-lets''), which are specialized .NET classes implementing a particular operation. These work by accessing data in different data stores, like the file system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows Task Scheduler
Task Scheduler (formerly Scheduled Tasks) is a job scheduler in Microsoft Windows that launches computer programs or scripts at pre-defined times or after specified time intervals. Microsoft introduced this component in the Microsoft Plus! for Windows 95 as ''System Agent.'' Its core component is an eponymous Windows service. The Windows Task Scheduler infrastructure is the basis for the Windows PowerShell scheduled jobs feature introduced with PowerShell v3. Task Scheduler can be compared to cron or anacron on Unix-like operating systems. This service should not be confused with the scheduler, which is a core component of the OS kernel that allocates CPU resources to processes already running. Versions Task Scheduler 1.0 Task Scheduler 1.0 is included with Windows NT 4.0 (with Internet Explorer 4.0 or later), Windows 2000, Windows XP and Windows Server 2003. It runs as a Windows Service, and the task definitions and schedules are stored in binary .job files. Tasks a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Command-line Argument
A command-line interface (CLI) is a means of interacting with software via command (computing), commands each formatted as a line of text. Command-line interfaces emerged in the mid-1960s, on computer terminals, as an interactive and more user-friendly alternative to the non-interactive mode available with punched cards. For a long time, a CLI was the most common interface for software, but today a graphical user interface (GUI) is more common. Nonetheless, many programs such as operating system and software development utility software, utilities still provide CLI. A CLI enables automation, automating computer program, programs since commands can be stored in a scripting language, script computer file, file that can be used repeatedly. A script allows its contained commands to be executed as group; as a program; as a command. A CLI is made possible by command-line interpreters or command-line processors, which are programs that execute input commands. Alternatives to a CLI ...

Microsoft Windows
Windows is a Product lining, product line of Proprietary software, proprietary graphical user interface, graphical operating systems developed and marketed by Microsoft. It is grouped into families and subfamilies that cater to particular sectors of the computing industry – Windows (unqualified) for a consumer or corporate workstation, Windows Server for a Server (computing), server and Windows IoT for an embedded system. Windows is sold as either a consumer retail product or licensed to Original equipment manufacturer, third-party hardware manufacturers who sell products Software bundles, bundled with Windows. The first version of Windows, Windows 1.0, was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). The name "Windows" is a reference to the windowing system in GUIs. The 1990 release of Windows 3.0 catapulted its market success and led to various other product families ...

Virtual Private Network
Virtual private network (VPN) is a network architecture for virtually extending a private network (i.e. any computer network which is not the public Internet) across one or multiple other networks which are either untrusted (as they are not controlled by the entity aiming to implement the VPN) or need to be isolated (thus making the lower network invisible or not directly usable). A VPN can extend access to a private network to users who do not have direct access to it, such as an office network allowing secure access from off-site over the Internet. This is achieved by creating a link between computing devices and computer networks by the use of network tunneling protocols. It is possible to make a VPN secure to use on top of insecure communication medium (such as the public internet) by choosing a tunneling protocol that implements encryption. This kind of VPN implementation has the benefit of reduced costs and greater flexibility, with respect to dedicated communication li ...

Brute-force Attack
In cryptography, a brute-force attack or exhaustive key search is a cryptanalytic attack that consists of an attacker submitting many possible keys or passwords with the hope of eventually guessing correctly. This strategy can theoretically be used to break any form of encryption that is not information-theoretically secure. However, in a properly designed cryptosystem the chance of successfully guessing the key is negligible. When cracking passwords, this method is very fast when used to check all short passwords, but for longer passwords other methods such as the dictionary attack are used because a brute-force search takes too long. Longer passwords, passphrases and keys have more possible values, making them exponentially more difficult to crack than shorter ones due to diversity of characters. Brute-force attacks can be made less effective by obfuscating the data to be encoded making it more difficult for an attacker to recognize when the code has been cracked or by ma ...

Phishing
Phishing is a form of social engineering and a scam where attackers deceive people into revealing sensitive information or installing malware such as viruses, worms, adware, or ransomware. Phishing attacks have become increasingly sophisticated and often transparently mirror the site being targeted, allowing the attacker to observe everything while the victim navigates the site, and transverses any additional security boundaries with the victim. As of 2020, it is the most common type of cybercrime, with the Federal Bureau of Investigation's Internet Crime Complaint Center reporting more incidents of phishing than any other type of cybercrime. The term "phishing" was first recorded in 1995 in the cracking toolkit AOHell, but may have been used earlier in the hacker magazine '' 2600''. It is a variation of ''fishing'' and refers to the use of lures to "fish" for sensitive information. Measures to prevent or reduce the impact of phishing attacks include legislation, user educa ...

Remote Desktop Protocol
Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft Corporation which provides a user with a graphical interface to connect to another computer over a network connection. The user employs RDP client software for this purpose, while the other computer must run RDP server software. Several clients exist for most versions of Microsoft Windows (including Windows Mobile but the support has ended), Linux (for example Remmina), Unix, macOS, iOS, Android, and other operating systems. RDP servers are built into the server and professional editions of Windows operating systems but not home editions; an RDP server for Unix and OS X also exists (for example xrdp). By default, the server listens on TCP port 3389 Microsoft KB article 306759, revision 2.2. and UDP port 3389. Microsoft currently refers to their official RDP client software as Remote Desktop Connection, formerly "Terminal Services Client". The protocol is an extension of the ITU-T T.128 applic ...
