A dictionary attack is based on trying all the strings in a pre-arranged listing. Such attacks originally used words found in a dictionary (hence the phrase dictionary attack); [2] however, now there are much larger lists available on the open Internet containing hundreds of millions of passwords recovered from past data breaches. [3]
The attack also renewed concerns among some healthcare practitioners regarding ongoing efforts to centralize electronic patient data in Singapore. Plans to pass laws in late 2018 making it compulsory for healthcare providers to submit data regarding patient visits and diagnoses to the National Electronic Health Record system were postponed.

A vulnerability assessment is the process of identifying, quantifying, and prioritizing (or ranking) the vulnerabilities in a system. Examples of systems for which vulnerability assessments are performed include, but are not limited to, information technology systems, energy supply systems, water supply systems, transportation systems, and communication systems.
Common Vulnerabilities and Exposures (CVE) is a dictionary of common names (i.e., CVE Identifiers) for publicly known information security vulnerabilities. CVE's common identifiers make it easier to share data across separate network security databases and tools, and provide a baseline for evaluating the coverage of an organization's security ...
It was the most significant cybercrime attack on an Irish state agency and the largest known attack against a health service computer system. [5] [6] Bloomberg News reported that the attackers used the Conti ransomware. [7] The group responsible was identified as a criminal gang known as Wizard Spider, believed to be operating from Russia.
Recommended Mitigation; Since this is an attack pattern, the recommended mitigation for the attack can be listed here in brief. Ideally, this will point the user to a more thorough mitigation pattern for this class of attack. Related Patterns; This section will have a few subsections such as Related Patterns, Mitigation Patterns, Security ...
The known-plaintext attack (KPA) is an attack model for cryptanalysis where the attacker has access to both the plaintext (called a crib) and its encrypted version . These can be used to reveal secret keys and code books. The term "crib" originated at Bletchley Park, the British World War II decryption operation, where it was defined as:
A "passive attack" attempts to learn or make use of information from the system but does not affect system resources, compromising confidentiality. A threat is a potential for violation of security, which exists when there is a circumstance, capability, action, or event that could breach security and cause harm.
