A blended threat (also known as a blended attack) is a software exploit that involves a combination of attacks against different vulnerabilities. Blended threats can be any software that exploits techniques to attack and propagate threats, for example worms, trojan horses, and computer viruses. Description Complex threats consist of two or more attacks, such as multiple attacks of the same kind. Examples of complex threats include a series of coordinated physical hostilities, such as the Paris terrorist attacks in 2015 or a combination of threats such as a cyberattack and a distinct physical attack, which may be coordinated. In more recent years , cyber attacks have demonstrated increased ability to impact physical systems, such as Stuxnet, Triton or Trisis malware, and have caused ransomware attacks such as WannaCry and Netwalker By recognizing computer system threats occur from potential physical hazards, the term "blended threat" has also been defined as a natural, accidental, or purposeful physical or virtual danger that has the potential for crossover impacts or to harm life, information, operations, environment, and property. This is an adaptation based on terminology from the 2010 US Department of Homeland Security's Risk Lexicon. Illustrating how rapidly and dangerously this can play out, Sarah Coble (writing in Infosecurity Mag on 12 June 2020 reported, that "the life of Jessica Hatch, a Houston business owner, was “threatened after cyber-criminals hacked into her company’s social media account and posted racist messages". The founder and CEO of Infinity Diagnostics Center said that her company’s Instagram account was compromised… by an unknown malicious hacker. After gaining access to the account, the threat actor uploaded multiple stories designed to paint Hatch and her business as racist.” In this post "Blended Threats: Protests! Hacking? Death Threats!?!", Gate 15 highlighted that risk management processes need to account for our complex and blended threat environment. On 6 September 2020, the Argentina's official immigration agency, Dirección Nacional de Migraciones, suffered a Netwalker ransomware attack that temporarily halted border crossing into and out of the country. Blended threats, in the form of a cyber attack, have evolved to cause a loss of life. On 10 September 2020, German authorities say a hacker attack caused the failure of IT systems at the University Hospital Düsseldorf (UKD) Duesseldorf, and a woman who needed urgent admission died after she had to be taken to another city for treatment. According to The Guardian, in a worst-case scenario,
