Mimikatz
Mimikatz is both an Exploit (computer security), exploit on Microsoft Windows that extracts passwords stored in memory and software that performs that exploit. It was created by France, French programmer Benjamin Delpy and is French slang for "cute cats". History Benjamin Delpy discovered a flaw in Microsoft Windows that holds both an encrypted copy of a password and a key that can be used to decipher it in memory at the same time. He contacted Microsoft in 2011 to point out the flaw, but Microsoft replied that it would require the machine to be already compromised. Delpy realised that the flaw could be used to gain access to non-compromised machines on a network from a compromised machine. He released the first version of the software in May 2011 as Proprietary software, closed source software. In September 2011, the exploit was used in the DigiNotar hack. Russian conference He spoke about the software at a conference in 2012. Once during the conference, he returned to his room t ...

Petya And NotPetya
Petya is a family of encrypting malware that was first discovered in 2016. The malware targets Microsoft Windows–based systems, infecting the master boot record to execute a payload that encrypts a hard drive's file system table and prevents Windows from booting. It subsequently demands that the user make a payment in Bitcoin in order to regain access to the system. Variants of Petya were first seen in March 2016, which propagated via infected e-mail attachments. In June 2017, a new variant of Petya was used for a global cyberattack, primarily targeting Ukraine. The new variant propagates via the EternalBlue exploit, which is generally believed to have been developed by the U.S. National Security Agency (NSA), and was used earlier in the year by the WannaCry ransomware. Kaspersky Lab referred to this new version as NotPetya to distinguish it from the 2016 variants, due to these differences in operation. In addition, although it purports to be ransomware, this variant was modi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 tho ...

Varonis Systems
Varonis Systems is a software company with headquarters in New York City with R&D offices in Herzliya, Israel. They developed a security software platform that allows organizations to track, visualize, analyze and protect unstructured data. Varonis performs User Behavior Analytics (UBA) that identifies abnormal behavior from cyberattacks. Their software extracts metadata from an enterprise's IT infrastructure and uses this information to map relationships among employees, data objects, content, and usage. History Varonis Systems was founded in 2005 by Yaki Faitelson and Ohad Korkus, in order to address security issues such as file activity tracking, information rights management, and access control. Prior to Varonis, Faitelson and Korkus worked at the global professional services and systems integration divisions of NetVision and NetApp. Faitelson and Korkus invented a solution that would retrieve metadata contained in file systems. They brought in Dr. Jacob Goldberger, an exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Bundestag
The Bundestag (, "Federal Diet") is the German federal parliament. It is the only federal representative body that is directly elected by the German people. It is comparable to the United States House of Representatives or the House of Commons of the United Kingdom. The Bundestag was established by Title III of the Basic Law for the Federal Republic of Germany (, ) in 1949 as one of the legislative bodies of Germany and thus it is the historical successor to the earlier Reichstag. The members of the Bundestag are representatives of the German people as a whole, are not bound by any orders or instructions and are only accountable to their electorate. The minimum legal number of members of the Bundestag (german: link=no, Mitglieder des Bundestages) is 598; however, due to the system of overhang and leveling seats the current 20th Bundestag has a total of 736 members, making it the largest Bundestag to date and the largest freely elected national parliamentary chamber in the wo ...

Carbanak
Carbanak is an APT-style campaign targeting (but not limited to) financial institutions, that was discovered in 2014 by the Russian cyber security company Kaspersky Lab. It utilizes malware that is introduced into systems running Microsoft Windows using phishing emails, which is then used to steal money from banks via macros in documents. The hacker group is said to have stolen over 900 million dollars, from the banks as well as from over a thousand private customers. The criminals were able to manipulate their access to the respective banking networks in order to steal the money in a variety of ways. In some instances, ATMs were instructed to dispense cash without having to locally interact with the terminal. Money mules would collect the money and transfer it over the SWIFT network to the criminals’ accounts, Kaspersky said. The Carbanak group went so far as to alter databases and pump up balances on existing accounts and pocketing the difference unbeknownst to the user whose ...

Privilege Escalation
Privilege escalation is the act of exploiting a bug, a design flaw, or a configuration oversight in an operating system or software application to gain elevated access to resources that are normally protected from an application or user. The result is that an application with more privileges than intended by the application developer or system administrator can perform unauthorized actions. Background Most computer systems are designed for use with multiple user accounts, each of which has abilities known as privileges. Common privileges include viewing and editing files or modifying system files. Privilege escalation means users receive privileges they are not entitled to. These privileges can be used to delete files, view private information, or install unwanted programs such as viruses. It usually occurs when a system has a bug that allows security to be bypassed or, alternatively, has flawed design assumptions about how it will be used. Privilege escalation occurs in two ...

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).
