Cybercrime encompasses a wide range of criminal activities that are carried out using digital devices and/or networks. These crimes involve the use of technology to commit fraud, identity theft, data breaches, computer viruses, scams, and expanded upon in other malicious acts. Cybercriminals exploit vulnerabilities in computer systems and networks to gain unauthorized access, steal sensitive information, disrupt services, and cause financial or reputational harm to individuals, organizations, and governments.
A security hacker or security researcher is someone who explores methods for breaching defenses and exploiting weaknesses in a computer system or network. Hackers may be motivated by a multitude of reasons, such as profit, protest, information gathering, challenge, recreation, or evaluation of a system weaknesses to assist in formulating defenses against potential hackers.

The Lazarus Group is a hacker group made up of an unknown number of individuals, alleged to be run by the government of North Korea. While not much is known about the Lazarus Group, researchers have attributed many cyberattacks to them since 2010. Originally a criminal group, the group has now been designated as an advanced persistent threat due to intended nature, threat, and wide array of methods used when conducting an operation. Names given by cybersecurity organizations include Hidden Cobra and ZINC or Diamond Sleet. According to North Korean defector Kim Kuk-song, the unit is internally known in North Korea as 414 Liaison Office.

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 was propagated 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.
Alex Stamos is an American computer scientist and adjunct professor at Stanford University's Center for International Security and Cooperation.

The Cybersecurity and Infrastructure Security Agency (CISA) is a component of the United States Department of Homeland Security (DHS) responsible for cybersecurity and infrastructure protection across all levels of government, coordinating cybersecurity programs with U.S. states, and improving the government's cybersecurity protections against private and nation-state hackers.
Internet security awareness or Cyber security awareness refers to how much end-users know about the cyber security threats their networks face, the risks they introduce and mitigating security best practices to guide their behavior. End users are considered the weakest link and the primary vulnerability within a network. Since end-users are a major vulnerability, technical means to improve security are not enough. Organizations could also seek to reduce the risk of the human element. This could be accomplished by providing security best practice guidance for end users' awareness of cyber security. Employees could be taught about common threats and how to avoid or mitigate them.
Bugcrowd is a crowdsourced security platform. It was founded in 2012, and in 2019 it was one of the largest bug bounty and vulnerability disclosure companies on the internet. Bugcrowd runs bug bounty programs and also offers a range of penetration testing services it refers to as "Penetration Testing as a Service" (PTaaS), as well as attack surface management.
Ryuk is a type of ransomware known for targeting large, public-entity Microsoft Windows cybersystems. It typically encrypts data on an infected system, rendering the data inaccessible until a ransom is paid in untraceable bitcoin. Ryuk is believed to be used by two or more criminal groups, most likely Russian or Ukrainian, who target organizations rather than individual consumers.
A global wave of cyberattacks and data breaches began in January 2021 after four zero-day exploits were discovered in on-premises Microsoft Exchange Servers, giving attackers full access to user emails and passwords on affected servers, administrator privileges on the server, and access to connected devices on the same network. Attackers typically install a backdoor that allows the attacker full access to impacted servers even if the server is later updated to no longer be vulnerable to the original exploits. As of 9 March 2021, it was estimated that 250,000 servers fell victim to the attacks, including servers belonging to around 30,000 organizations in the United States, 7,000 servers in the United Kingdom, as well as the European Banking Authority, the Norwegian Parliament, and Chile's Commission for the Financial Market (CMF).
Log4Shell (CVE-2021-44228) is a zero-day vulnerability reported in November 2021 in Log4j, a popular Java logging framework, involving arbitrary code execution. The vulnerability had existed unnoticed since 2013 and was privately disclosed to the Apache Software Foundation, of which Log4j is a project, by Chen Zhaojun of Alibaba Cloud's security team on 24 November 2021. Before an official CVE identifier was made available on 10 December 2021, the vulnerability circulated with the name "Log4Shell", given by Free Wortley of the LunaSec team, which was initially used to track the issue online. Apache gave Log4Shell a CVSS severity rating of 10, the highest available score. The exploit was simple to execute and is estimated to have had the potential to affect hundreds of millions of devices.
