WannaCry Ransomware Attack
The WannaCry ransomware attack was a worldwide cyberattack in May 2017 by the WannaCry ransomware cryptoworm, which targeted computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in the Bitcoin cryptocurrency. It propagated by using EternalBlue, an exploit developed by the United States National Security Agency (NSA) for Windows systems. EternalBlue was stolen and leaked by a group called The Shadow Brokers a month prior to the attack. While Microsoft had released patches previously to close the exploit, much of WannaCry's spread was from organizations that had not applied these, or were using older Windows systems that were past their end-of-life. These patches were imperative to organizations' cyber security but many were not implemented due to ignorance of their importance. Some have claimed a need for 24/7 operation, aversion to risking having formerly working applications breaking because of patch changes, lack of person ...

Cyberattack
A cyberattack is any offensive maneuver that targets computer information systems, computer networks, infrastructures, or personal computer devices. An attacker is a person or process that attempts to access data, functions, or other restricted areas of the system without authorization, potentially with malicious intent. Depending on the context, cyberattacks can be part of cyber warfare or cyberterrorism. A cyberattack can be employed by sovereign states, individuals, groups, societies or organisations and it may originate from an anonymous source. A product that facilitates a cyberattack is sometimes called a cyber weapon. Cyber attacks have increased with an alarming rate for the last few years A cyberattack may steal, alter, or destroy a specified target by hacking into a susceptible system. Cyberattacks can range from installing spyware on a personal computer to attempting to destroy the infrastructure of entire nations. Legal experts are seeking to limit the use of the ...

The Shadow Brokers
The Shadow Brokers (TSB) is a hacker group who first appeared in the summer of 2016. They published several leaks containing hacking tools, including several zero-day exploits, from the "Equation Group" who are widely suspected to be a branch of the National Security Agency (NSA) of the United States. Specifically, these exploits and vulnerabilities targeted enterprise firewalls, antivirus software, and Microsoft products. The Shadow Brokers originally attributed the leaks to the Equation Group threat actor, who have been tied to the NSA's Tailored Access Operations unit. Name and alias Several news sources noted that the group's name was likely in reference to a character from the ''Mass Effect'' video game series. Matt Suiche quoted the following description of that character: "The Shadow Broker is an individual at the head of an expansive organization which trades in information, always selling to the highest bidder. The Shadow Broker appears to be highly competent at its t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Server Message Block
Server Message Block (SMB) is a communication protocol originally developed in 1983 by Barry A. Feigenbaum at IBM and intended to provide shared access to files and printers across nodes on a network of systems running IBM's OS/2. It also provides an authenticated inter-process communication (IPC) mechanism. In 1987, Microsoft and 3Com implemented SMB in LAN Manager for OS/2, at which time SMB used the NetBIOS service atop the NetBIOS Frames protocol as its underlying transport. Later, Microsoft implemented SMB in Windows NT 3.1 and has been updating it ever since, adapting it to work with newer underlying transports: TCP/IP and NetBT. SMB implementation consists of two vaguely named Windows services: "Server" (ID: LanmanServer) and "Workstation" (ID: LanmanWorkstation). It uses NTLM or Kerberos protocols for user authentication. In 1996, Microsoft published a version of SMB 1.0 with minor modifications under the Common Internet File System (CIFS ) moniker. CIFS was compatibl ...

Exploit (computer Security)
An exploit (from the English verb ''to exploit'', meaning "to use something to one’s own advantage") is a piece of software, a chunk of data, or a sequence of commands that takes advantage of a bug or vulnerability to cause unintended or unanticipated behavior to occur on computer software, hardware, or something electronic (usually computerized). Such behavior frequently includes things like gaining control of a computer system, allowing privilege escalation, or a denial-of-service (DoS or related DDoS) attack. In lay terms, some exploit is akin to a 'hack'. Classification There are several methods of classifying exploits. The most common is by how the exploit communicates to the vulnerable software. A ''remote exploit'' works over a network and exploits the security vulnerability without any prior access to the vulnerable system. A ''local exploit'' requires prior access to the vulnerable system and usually increases the privileges of the person running the exploit past t ...

Microsoft Visual C++
Microsoft Visual C++ (MSVC) is a compiler for the C, C++ and C++/CX programming languages by Microsoft. MSVC is proprietary software; it was originally a standalone product but later became a part of Visual Studio and made available in both trialware and freeware forms. It features tools for developing and debugging C++ code, especially code written for the Windows API, DirectX and .NET. Many applications require redistributable Visual C++ runtime library packages to function correctly. These packages are often installed independently of applications, allowing multiple applications to make use of the package while only having to install it once. These Visual C++ redistributable and runtime packages are mostly installed for standard libraries that many applications use.

DoublePulsar
DoublePulsar is a backdoor implant tool developed by the U.S. National Security Agency's (NSA) Equation Group that was leaked by The Shadow Brokers in early 2017. The tool infected more than 200,000 Microsoft Windows computers in only a few weeks, and was used alongside EternalBlue in the May 2017 WannaCry ransomware attack. A variant of DoublePulsar was first seen in the wild in March 2016, as discovered by Symantec. Sean Dillon, senior analyst of security company RiskSense Inc., first dissected and inspected DoublePulsar. He said that the NSA exploits are "10 times worse" than the Heartbleed security bug, and use DoublePulsar as the primary payload. DoublePulsar runs in kernel mode, which grants cybercriminals a high level of control over the computer system. Once installed, it uses three commands: ping, kill, and exec Exec or EXEC may refer to: * Executive officer, a person responsible for running an organization * Executive producer, provides finance and guidance ...

Marcus Hutchins
Marcus Hutchins (born 1994), also known online as MalwareTech, is a British computer security researcher known for stopping the WannaCry ransomware attack. He is employed by cybersecurity firm Kryptos Logic. Hutchins is from Ilfracombe in Devon. Early life Hutchins is the elder son of Janet Hutchins, a Scottish nurse, and Desmond Hutchins, a Jamaican social worker. Around 2003, when Hutchins was nine years old, the parents moved the family from urban Bracknell, near London, to rural Devon. Hutchins had shown early aptitude with computers and learned simple hacking skills early on such as bypassing security on school computers to install video game software. In addition, he spent time learning to be a surf lifeguard. He became involved with an online forum that promoted malware development, more as a means to show off their skills to each other rather than for nefarious purposes. When he was about 14 years old, he created his own contribution, a password stealer based on Int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
