A cyberattack is any type of offensive maneuver employed by individuals or whole organizations that targets computer information systems, infrastructures, computer networks, and/or personal computer devices by various means of malicious acts usually originating from an anonymous source that either steals, alters, or destroys a specified target by hacking into a susceptible system.
These attacks are wide-ranging, global and do not seem to discriminate among governments and companies.
These attacks relate to inflicting damage on specific organizations.
These are politically motivated destructive attacks aimed at sabotage and espionage.
These attacks relate to stealing information from/about government organizations:
These attacks relate to stealing data of corporations related to proprietary methods or emerging products/services.
These attacks relate to stealing login information for specific web resources.
A supply chain attack is a cyber-attack that seeks to damage an organization by targeting less secure elements in the supply chain. A supply chain attack can occur in any industry, from the financial sector, oil industry, to a government sector. A supply chain attack can happen in software or hardware. Cybercriminals typically tamper with the manufacturing or distribution of a product by installing malware or hardware-based spying components. Symantec's 2019 Internet Security Threat Report states that supply chain attacks increased by 78 percent in 2018.
Cyberwarfare by China is the aggregate of all combative activities in the cyberspace which are taken by organs of the People's Republic of China, including affiliated advanced persistent threat (APT) groups, against other countries.
In computer security, a wiper is a class of malware intended to erase the hard drive or other static memory of the computer it infects, maliciously deleting data and programs.
A cyberattack occurs when there is an unauthorized action against computer infrastructure that compromises the confidentiality, integrity, or availability of its content.
Dexter is a computer virus or point of sale (PoS) malware which infects computers running Microsoft Windows and was discovered by IT security firm Seculert, in December 2012. It infects PoS systems worldwide and steals sensitive information such as credit and debit card information.
Seculert was a cloud-based cyber security technology company based in Petah Tikva, Israel. The company's technology was designed to detect breaches and advanced persistent threats (APTs), attacking networks. Seculert's business was based on malware research and the ability to uncover malware that has gone undetected by other traditional measures.
The Equation Group, classified as an advanced persistent threat, is a highly sophisticated threat actor suspected of being tied to the Tailored Access Operations (TAO) unit of the United States National Security Agency (NSA). Kaspersky Labs describes them as one of the most sophisticated cyber attack groups in the world and "the most advanced (...) we have seen", operating alongside the creators of Stuxnet and Flame. Most of their targets have been in Iran, Russia, Pakistan, Afghanistan, India, Syria and Mali.
Cozy Bear, classified by the United States federal government as advanced persistent threat APT29, is a Russian hacker group believed to be associated with one or more intelligence agencies of Russia. The Dutch General Intelligence and Security Service (AIVD) deduced from security camera footage that it is led by the Russian Foreign Intelligence Service (SVR), a view shared by the United States. Cybersecurity firm CrowdStrike also previously suggested that it may be associated with either the Russian Federal Security Service (FSB) or SVR. The group has been given various nicknames by other cybersecurity firms, including CozyCar, CozyDuke, Dark Halo, The Dukes, Midnight Blizzard, NOBELIUM, Office Monkeys, StellarParticle, UNC2452, and YTTRIUM.
CrowdStrike Holdings, Inc. is an American cybersecurity technology company based in Austin, Texas. It provides cloud workload and endpoint security, threat intelligence, and cyberattack response services. The company has been involved in investigations of several high-profile cyberattacks, including the 2014 Sony Pictures hack, the 2015–16 cyber attacks on the Democratic National Committee (DNC), and the 2016 email leak involving the DNC.
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.
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 cyber security, but many organizations did not apply them, citing a need for 24/7 operation, the risk of formerly working applications breaking because of the changes, lack of personnel or time to install them, or other reasons.
EternalBlue is computer exploit software developed by the U.S. National Security Agency (NSA). It is based on a vulnerability in Microsoft Windows that, at the time, allowed users to gain access to any number of computers connected to a network. The NSA had known about this vulnerability for several years but had not disclosed it to Microsoft yet, since they planned to use it as a defense mechanism against cyber attacks. In 2017, the NSA discovered that the software was stolen by a group of hackers known as the Shadow Brokers. Microsoft was informed of this and released security updates in March 2017 patching the vulnerability. While this was happening, the hacker group attempted to auction off the software, but did not succeed in finding a buyer. EternalBlue was then publicly released on April 14, 2017.
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.
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.
The city of Atlanta, Georgia was the subject of a ransomware attack which began in March 2018. The city recognized the attack on Thursday, March 22, 2018, and publicly acknowledged it was a ransomware attack.
In 2020, a major cyberattack suspected to have been committed by a group backed by the Russian government penetrated thousands of organizations globally including multiple parts of the United States federal government, leading to a series of data breaches. The cyberattack and data breach were reported to be among the worst cyber-espionage incidents ever suffered by the U.S., due to the sensitivity and high profile of the targets and the long duration in which the hackers had access. Within days of its discovery, at least 200 organizations around the world had been reported to be affected by the attack, and some of these may also have suffered data breaches. Affected organizations worldwide included NATO, the U.K. government, the European Parliament, Microsoft and others.
Lapsus$, stylised as LAPSUS$ and classified by Microsoft as Strawberry Tempest, was an international extortion-focused hacker group known for its various cyberattacks against companies and government agencies. The group was globally active, and has had members arrested in Brazil and the UK.
A wave of cyberattacks and data breaches began in June 2023 after a vulnerability was discovered in MOVEit, a managed file transfer software.
