Cyber War, a Strong Future Trend

first_img Currently we are under the impression that if there is a new world war, it will probably be in cyberspace, where there are neither laws nor restrictions, which can be a great advantage. The Internet also shows its dark side, maximized for use in military actions of espionage and sabotage, either by nations or any other non-governmental entity. The cybertroops may be used for both defense and for an ample offensive, hitting all sectors where there are connections and vulnerabilities. The problem is so present, that the United Nations studied a project to protect the state structures on the Internet and the organization of Cyber-Centers in NATO, anticipating the possibility that this new type of conflict will occur, and it is more possible today than a nuclear war. The threats generated by computer networks can be classified into five types, or what we call the 5Cs. A cyber threat is an effort to obtain non-authorized access to an online system, with the objective of extracting or manipulating data, violating the confidentiality, authenticity, integrity, or availability of the data within the system. Generally, it is performed by spyware, which may be introduced via legit software or via a Trojan virus. The same concept may be used for cyber espionage. Cyber war is defined as a group of actions adopted by countries against computer systems of other countries, with the objective of causing damage or interruption of services (see the Estonia case, in 2003, the first registered occurrence). Finally, Cyber terrorism is the use of the Internet to organize and execute attacks against critical computer networks, systems, and infra-structures, aiming to destroy or incapacitate them, as ideological motivations, causing chaos in the economy and inflicting fear in the population. We left cyber crime out, because of its criminal nature. In a way, their weapons are more precise and lethal than conventional weapons: until the super viruses are detected, they have already caused much irreparable damage to the opponent, similar to the effects of bacterial virus. A common characteristic of cyber war, as well as of other virtual threats, is that it becomes almost impossible to detect who initiated or sponsored such actions, because the trails left behind, most of the time, are part of the disinformation practice. However, the biggest threat to all countries is that they can also be triggered by non-governmental parties, driven or not by different motives, breaking a historical paradigm which governments previously initiated via their Armed Forces. *André Luís Woloszyn, Strategic Affairs Analyst By Dialogo February 12, 2013last_img read more

Latin America tops four million coronavirus cases

first_imgMore than four million coronavirus cases have been recorded in Latin America and the Caribbean, half of them in Brazil, according to an AFP tally based on official figures.The region passed the bleak milestone as Brazil reported a daily record of 67,860 new coronavirus cases Wednesday.Latin America is one of the hardest-hit regions in the world, with 4,040,925 recorded cases and 172,886 people killed by COVID-19. Mexico’s death toll has surged to become the fourth-highest in the world, at 40,400.The country surpassed Italy on Sunday, and now has more victims than anywhere but the United States, Brazil and Britain.Worldwide, the virus has infected more than 15 million people and killed nearly 625,000 since it emerged in China late last year.Brazil in particular has struggled to set a strategy for responding to the pandemic.President Jair Bolsonaro faces criticism for downplaying the virus and attacking social distancing measures adopted by state and local authorities.The far-right leader, who has regularly hit the streets mask-less for rallies by his supporters, has been in quarantine at the presidential palace since July 7 after contracting the virus himself.His office announced Wednesday he had again tested positive, saying he would continue his quarantine and suspend his upcoming travel plans.Bolsonaro, 65, argues the economic fallout from stay-at-home measures could be worse than the virus itself, and is instead pushing the unproven malaria drugs chloroquine and hydroxychloroquine as remedies, following in the footsteps of US President Donald Trump.Margareth Dalcomo, an expert at Brazil’s leading public-health institute, Fiocruz, said Bolsonaro’s hydroxychloroquine-pushing was “deplorable.””This politicization of the drug by the US and Brazilian presidents for murky reasons has no justification, and it deceives people,” she told AFP.”It has been proven this drug has no effect against COVID-19.”Bolsonaro is on his third health minister since the pandemic reached Brazil five months ago, after falling out with two doctors who previously held the post over their recommendations on containing the virus.The current minister, an interim, is Eduardo Pazuello, an army general with no prior medical experience.The World Health Organization voiced optimism last week that the outbreak in Brazil had finally reached a plateau, urging the country to use the opportunity to “take control.”But though the level of daily infections and deaths has stabilized, it remains high.The country has recorded an average of more than 37,000 infections and 1,050 deaths a day over the past week. Topics :center_img That is the highest caseload of any region except North America, and the highest death toll of any region except Europe.Brazil alone has registered 2.2 million cases and 82,771 deaths, the second-biggest outbreak in the world after the United States.Although many Latin American countries have begun relaxing stay-at-home measures, the virus is still spreading quickly across much of the region.Peru, Mexico and Chile are also on the list of the top 10 countries by total cases, with well over 300,000 each.last_img read more
