2017 Petya Cyberattack
A series of powerful cyberattacks using the Petya malware began on 27 June 2017 that swamped websites of Ukrainian organizations, including banks, ministries, newspapers and electricity firms. Similar infections were reported in France, Germany, Italy, Poland, Russia, United Kingdom, the United States and Australia. ESET estimated on 28 June 2017 that 80% of all infections were in Ukraine, with Germany second hardest hit with about 9%. On 28 June 2017, the Ukrainian government stated that the attack was halted. On 30 June 2017, the Associated Press reported experts agreed that Petya was masquerading as ransomware, while it was actually designed to cause maximum damage, with Ukraine being the main target. Approach Security experts believe the attack originated from an update of a Ukrainian tax accounting package called MeDoc (), developed by Intellect Service. MeDoc was widely used among tax accountants in Ukraine, and the software was the main option for accounting for ot ... [...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 compatible w ...

Bitcoin
Bitcoin ( abbreviation: BTC; sign: ₿) is a decentralized digital currency that can be transferred on the peer-to-peer bitcoin network. Bitcoin transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. The cryptocurrency was invented in 2008 by an unknown person or group of people using the name Satoshi Nakamoto. The currency began use in 2009, when its implementation was released as open-source software. The word "''bitcoin''" was defined in a white paper published on October 31, 2008. It is a compound of the words ''bit'' and ''coin''. The legality of bitcoin varies by region. Nine countries have fully banned bitcoin use, while a further fifteen have implicitly banned it. A few governments have used bitcoin in some capacity. El Salvador has adopted Bitcoin as legal tender, although use by merchants remains low. Ukraine has accepted cryptocurrency donations to fund the resistance to the 2022 Russ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Master File Table
New Technology File System (NTFS) is a proprietary software, proprietary journaling file system developed by Microsoft. Starting with Windows NT 3.1, it is the default file system of the Windows NT family. It superseded File Allocation Table (FAT) as the preferred filesystem on Windows and is supported in Linux and BSD as well. NTFS reading and writing support is provided using a free and open-source kernel implementation known as NTFS3 in Linux kernel, Linux and the NTFS-3G driver in BSD. By using the convert (command), convert command, Windows can convert FAT32/16/12 into NTFS without the need to rewrite all files. NTFS uses several files typically hidden from the user to store metadata about other files stored on the drive which can help improve speed and performance when reading data. Unlike FAT and High Performance File System (HPFS), NTFS supports access control lists (ACLs), filesystem encryption, transparent compression, sparse files and Journaling file system, file system j ...

Microsoft Windows
Windows is a group of several proprietary graphical operating system families developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. For example, Windows NT for consumers, Windows Server for servers, and Windows IoT for embedded systems. Defunct Windows families include Windows 9x, Windows Mobile, and Windows Phone. The first version of Windows 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). Windows is the most popular desktop operating system in the world, with 75% market share , according to StatCounter. However, Windows is not the most used operating system when including both mobile and desktop OSes, due to Android's massive growth. , the most recent version of Windows is Windows 11 for consumer PCs and tablets, Windows 11 Enterprise for corporations, and Windows Server 2022 for servers.

EternalBlue
EternalBlue is a computer exploit (computer security), exploit developed by the U.S. National Security Agency (NSA). It was leaked by the The Shadow Brokers, Shadow Brokers hacker group on April 14, 2017, one month after Microsoft released patches for the Vulnerability (computing), vulnerability. On May 12, 2017, the worldwide WannaCry ransomware used this exploit to attack unpatched computers. On June 27, 2017, the exploit was again used to help carry out the 2017 NotPetya cyberattack on more unpatched computers. The exploit was also reported to have been used since March 2016 by the Chinese hacking group Advanced persistent threat#APT groups, Buckeye (APT3), after they likely found and re-purposed the tool, as well as reported to have been used as part of the Retefe banking Trojan horse (computing), trojan since at least September 5, 2017. EternalBlue was among the several exploits used, in conjunction with the DoublePulsar Backdoor (computing), backdoor implant tool, in exe ...

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 ...

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 Inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
