Citadel (malware)
Citadel is a piece of massively-distributed malware based upon Zeus. It targets credentials stored in password managers such as Keepass, Password Safe and neXus Personal Security Client. By 2017 (it was first identified in 2011) Citadel had infected about 11 million computers worldwide and had caused over $500 million in losses. On March 20, 2017, having been extradited from Norway to the United States, a Russian computer science professional Mark Vartanyan pleaded guilty to a computer fraud charge for his part in developing the Control Panel for Citadel. In July 2017, he was sentenced to 5 years in federal prison.

Malware
Malware (a portmanteau for ''malicious software'') is any software intentionally designed to cause disruption to a computer, server, client, or computer network, leak private information, gain unauthorized access to information or systems, deprive access to information, or which unknowingly interferes with the user's computer security and privacy. By contrast, software that causes harm due to some deficiency is typically described as a software bug. Malware poses serious problems to individuals and businesses on the Internet. According to Symantec's 2018 Internet Security Threat Report (ISTR), malware variants number has increased to 669,947,865 in 2017, which is twice as many malware variants as in 2016. Cybercrime, which includes malware attacks as well as other crimes committed by computer, was predicted to cost the world economy $6 trillion USD in 2021, and is increasing at a rate of 15% per year. Many types of malware exist, including computer viruses, worms, Trojan ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeus (malware)
Zeus, ZeuS, or Zbot is a Trojan horse malware package that runs on versions of Microsoft Windows. While it can be used to carry out many malicious and criminal tasks, it is often used to steal banking information by man-in-the-browser keystroke logging and form grabbing. It is also used to install the CryptoLocker ransomware. Zeus is spread mainly through drive-by downloads and phishing schemes. First identified in July 2007 when it was used to steal information from the United States Department of Transportation, it became more widespread in March 2009. In June 2009 security company Prevx discovered that Zeus had compromised over 74,000 FTP accounts on websites of such companies as the Bank of America, NASA, Monster.com, ABC, Oracle, Play.com, Cisco, Amazon, and ''BusinessWeek''. Similarly to Koobface, Zeus has also been used to trick victims of technical support scams into giving the scam artists money through pop-up messages that claim the user has a virus, when in real ...

Password Manager
A password manager is a computer program that allows users to store and manage their passwords for local applications and online services. In many cases software used to manage passwords allow also generate strong passwords and fill forms. Password manager can be delivered as a one of or mixed of: computer application, mobile application, web browser extension, web based service, portable software for USB units. A password manager assists in generating and retrieving complex passwords, storing such passwords in an encrypted database, or calculating them on demand. Depending on the type of password manager used and on the functionality offered by its developers, the encrypted database is either stored locally on the user's device or stored remotely through an online cloud storage. Password managers typically require a user to generate and remember one "master" password to unlock and access information stored in their databases. Modern password managers increase security ...

Keepass
KeePass Password Safe is a free and open-source password manager primarily for Windows. It officially supports macOS and Linux operating systems through the use of Mono. Additionally, there are several unofficial ports for Windows Phone, Android, iOS, and BlackBerry devices. KeePass stores usernames, passwords, and other fields, including free-form notes and file attachments, in an encrypted file. This file can be protected by any combination of a master password, a key file, and the current Windows account details. By default, the KeePass database is stored on a local file system (as opposed to cloud storage). KeePass supports a number of plugins. It has a password generator and synchronization function, supports two-factor authentication, and has a ''Secure Desktop'' mode. It can use a two-channel auto-type obfuscation feature to offer additional protection against keyloggers. KeePass can import from over 30 other most commonly used password managers. A 2017 Consu ...

NeXus Personal Security Client
NEXUS is a joint Canada Border Services Agency and U.S. Customs and Border Protection-operated Trusted Traveler and expedited border control program designed for pre-approved, low-risk travelers. Members of the program can avoid waits at border entry points by using reserved lanes at land crossings into Canada and the United States (including from Mexico), by using self-serve kiosks at airports in Canada, the US and some international locations, or by phoning border officials for a marine entry. A NEXUS membership card is a valid document under the Western Hemisphere Travel Initiative (WHTI), so it can be used in place of a passport, including by air if flying between the US and Canada. However, carrying a valid passport is still recommended, in the rare event that a flight is diverted to an airport without NEXUS support. History NEXUS began as a pilot project in 2000 at the Port Huron–Sarnia border crossing to reduce traffic congestion. At the time, delay-free crossing was ava ...

Federal Prison
A federal prison is operated under the jurisdiction of a federal government as opposed to a state or provincial body. Federal prisons are used for convicts who violated federal law (U.S., Mexico), inmates considered dangerous (Brazil), or those sentenced to longer terms of imprisonment (Canada). Not all federated countries have a legal concept of "federal prison". Australia The Australian federal government does not directly control most prisons or detention facilities. There are a relatively small number of federal detention facilities, consisting of military detention facilities (such as the Defence Force Correctional Establishment), immigration detention facilities, and holding cells in Australian Federal Police stations in some territories. The vast majority of criminal prosecutions in Australia take place within state or territory court systems under state or territory law, however a relatively small number of prosecutions in state and federal courts occur under federal ...

Conficker
Conficker, also known as Downup, Downadup and Kido, is a computer worm targeting the Microsoft Windows operating system that was first detected in November 2008. It uses flaws in Windows OS software and dictionary attacks on administrator passwords to propagate while forming a botnet, and has been unusually difficult to counter because of its combined use of many advanced malware techniques. The Conficker worm infected millions of computers including government, business and home computers in over 190 countries, making it the largest known computer worm infection since the 2003 Welchia. Despite its wide propagation, the worm did not do much damage, perhaps because its authors – believed to have been Ukrainian citizens – did not dare use it because of the attention it drew. Four men were arrested, and one pled guilty and was sentenced to four years in prison. Prevalence Estimates of the number of infected computers were difficult because the virus changed its propagatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Command And Control (malware)
A botnet is a group of Internet-connected devices, each of which runs one or more bots. Botnets can be used to perform Distributed Denial-of-Service (DDoS) attacks, steal data, send spam, and allow the attacker to access the device and its connection. The owner can control the botnet using command and control (C&C) software. The word "botnet" is a portmanteau of the words "robot" and " network". The term is usually used with a negative or malicious connotation. Overview A botnet is a logical collection of Internet-connected devices, such as computers, smartphones or Internet of things (IoT) devices whose security have been breached and control ceded to a third party. Each compromised device, known as a "bot," is created when a device is penetrated by software from a ''malware'' (malicious software) distribution. The controller of a botnet is able to direct the activities of these compromised computers through communication channels formed by standards-based network protocols, ...

Gameover ZeuS
GameOverZeus is a peer-to-peer botnet based on components from the earlier ZeuS trojan. The malware was created by Russian hacker Evgeniy Mikhailovich Bogachev. It is believed to have been spread through use of the Cutwail botnet. Unlike its predecessor the ZeuS trojan, Gameover ZeuS uses an encrypted peer-to-peer communication system to communicate between its nodes and its command and control servers, greatly reducing its vulnerability to law enforcement operations. The algorithm used appears to be modeled on the Kademlia P2P protocol. Scammers control and monitor Gameover ZeuS via command and control (C&C) servers. The virus establishes the connection to the server as soon as its malicious executable installs on the computer, at which point it can disable certain system processes, download and launch executables, or delete essential system files, making the system unusable. According to a report by Symantec, Gameover ZeuS has largely been used for banking fraud and distributi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Tovar
Operation Tovar is an international collaborative operation carried out by law enforcement agencies from multiple countries against the Gameover ZeuS botnet, which is believed by the investigators to have been used in bank fraud and the distribution of the CryptoLocker ransomware. Participants include the U.S. Department of Justice, Europol, the FBI and the U.K. National Crime Agency, South African Police Service, together with a number of security companies and academic researchers, including Dell SecureWorks, Deloitte Cyber Risk Services, Microsoft Corporation, Abuse.ch, Afilias, F-Secure, Level 3 Communications, McAfee, Neustar, Shadowserver, Anubisnetworks, Symantec, Heimdal Security, Sophos and Trend Micro, and academic researchers from Carnegie Mellon University, the Georgia Institute of Technology, VU University Amsterdam and Saarland University.
