Le Centre canadien pour la cybersécurité publie l’Évaluation des cybermenaces nationales 2023-2024

Le Centre canadien pour la cybersécurité (Centre pour la cybersécurité) a publié son Évaluation des cybermenaces nationales 2023-2024, un rapport qui se veut une mise en garde en ce qui concerne le nombre croissant de cybermenaces parrainées par des États et motivées par le gain financier qui sont susceptibles de toucher les Canadiens, et les efforts déployés par les auteurs de menace étrangers pour influencer les Canadiens au moyen de la mésinformation, de la désinformation et de la malinformation dans le cyberespace.

Ce rapport fait la lumière sur les cybermenaces les plus courantes qui ciblent les Canadiens et les organisations canadiennes, indique la probabilité que surviennent de telles cybermenaces et explique comment elles évolueront au cours des années à venir.

Cette évaluation non classifiée révèle que les rançongiciels sont presque assurément la forme la plus perturbatrice de cybercriminalité à laquelle sont confrontés les Canadiens et qu'ils représentent une menace omniprésente pour les organisations canadiennes. On y indique également que les infrastructures essentielles risquent de plus en plus d'être visées par des activités de cybermenace. Cela dit, s'il n'y a aucune hostilité internationale directe contre le Canada, il est improbable que des auteurs de menace parrainés par des États perturbent volontairement les infrastructures essentielles du Canada.

Le Centre pour la cybersécurité estime que les activités de cybermenace parrainées par des États ont des répercussions sur les Canadiens. En effet, les auteurs de menace étatiques peuvent cibler des activistes et des membres de certaines diasporas au Canada, des organisations canadiennes et leur propriété intellectuelle aux fins d'espionnage, et des particuliers pour obtenir un gain financier. Selon ses observations, les auteurs de cybermenace tentent d'influencer les Canadiens en ayant recours à la mésinformation, à la désinformation et à la malinformation (MDM) et on juge que l'exposition de la population canadienne à la MDM augmentera presque certainement dans les deux prochaines années.

Par ailleurs, l'évaluation indique que les technologies perturbatrices, comme la cryptomonnaie, l'apprentissage machine et l'informatique quantique, offrent de nouvelles possibilités aux auteurs de cybermenace et constituent, par le fait même, de nouvelles menaces pour les Canadiens.

La cybersécurité fait partie des priorités du gouvernement du Canada en raison de l'évolution constante des menaces. Les investissements en ce sens comprennent, entre autres, l'adoption de la Loi sur le CST qui a permis au Centre de la sécurité des télécommunications d'intercepter et de contrer plus efficacement les menaces étrangères. Le budget 2022 a accordé à l'organisme 875,2 M$ pour soutenir sa capacité à contrer et à prévenir les cyberattaques et à se défendre contre elles. Ces investissements protégeront les infrastructures essentielles, les systèmes gouvernementaux et la sécurité nationale du Canada. Pour une première fois cette année, le Centre pour la cybersécurité a également regroupé ses meilleurs avis et conseils pour les Canadiens, les organisations canadiennes et les infrastructures essentielles en tenant compte des menaces à la cybersécurité mentionnées dans l'évaluation.

Contexte

Il s'agit de la troisième édition de l'Évaluation des cybermenaces nationales du Centre pour la cybersécurité. La première a été publiée en décembre 2018.

En plus de l'Évaluation des cybermenaces nationales 2023-2024, le Centre pour la cybersécurité lance également une mise à jour de son document Introduction à l'environnement de cybermenace. Ce document de référence offre de l'information de base sur l'environnement de cybermenace, ainsi que sur les auteurs de cybermenace, leurs motivations, leurs techniques et les outils qu'ils utilisent dans le contexte canadien.

À propos du Centre pour la cybersécurité

Relevant du Centre de la sécurité des télécommunications, le Centre pour la cybersécurité est l'autorité technique au Canada et la seule source unifiée de conseils, d'orientation, de services et de soutien pour toutes les questions opérationnelles liées à la cybersécurité.

Le Centre pour la cybersécurité travaille avec les entreprises et les organisations qui ont été victimes d'un cyberincident pour atténuer les répercussions des incidents de cybersécurité.

    AETE must move to make room for new fighters says commanding officer

    Kelly-Anne Riess ADJUSTCOMMENTPRINT Moving the Canadian military's Aerospace Engineering Test Establishment out of Cold Lake to Ottawa is the only way 4 Wing can grow to accommodate new fighters, says AETE commanding officer Col. Eric Grandmont, referring to feasibility studies conducted by the Air Force. He said the loss of AETE will be offset by a gain for 4 Wing. “We are planning ahead for the long-term future of Canada's fighters,” he said. “The RCAF is committed to Cold Lake and Bagotville as our fighter bases, and there will be significant investment in these areas to prepare for the arrival of the future fighters.” The new aircraft will require an expansion of 4 Wing. Facilities will need to be updated and the current AETE building, which is the newest and second largest hanger on the base, will need to be repurposed. Canada is currently in the process of purchasing 25 used fighter aircraft from Australia and buying another 88 new jets to replace the existing fleet of CF-18s. The costs for relocating AETE are included in the $470 million the Liberal government has set aside for buying the used Australian F-18 fighter jets. Grandmont said he is hoping the transition plan for AETE will be approved by this spring. The move, which would not take place before the summer of 2021, could affect one-third of AETE, which employs 166 military personnel and 22 public servants. The remainder would be reassigned elsewhere in the air force, either in Cold Lake or other military bases. “We are trying to minimize the impact on the city,” said Grandmont, adding the current plan is to stagger his staff's moves to Ottawa. He said some of the positions in question are currently vacant and, if filled, those employees would start their jobs immediately in the nation's capital instead of coming to Cold Lake in the interim. Also, some public servants currently working for AETE in Cold Lake are close to retirement and would likely choose to end their careers and stay in Alberta's north instead of moving to Ottawa. Grandmont says once the unit relocates it will augment its staff with civilian test pilots. “We are hoping to recruit retired members back to the unit once it's in Ottawa,” said Grandmont, adding that moving AETE would put the unit in a central position to service all Canadian Forces aircraft, many of which are in Eastern Canada. “Our people spend a lot of time on the road. They can be away for five or six months a year,” said Grandmont. Recently, some AETE personnel spent seven months in Petawawa, Ont. doing the work necessary to have two Chinooks available to send to Mali, where Canada has been providing emergency medical evacuation for the United Nations peacekeeping mission going on in that country. There are 19 fleets in the Canadian Air Force and only two of them are in Cold Lake—the CF-18 and the Griffon helicopters, said Grandmont. Other aircraft, like the CC-130J Hercules, CC-17 Globemaster and CC-150 Polaris are all based in Trenton, Ont. The CC-144 Challengers are in Ottawa. The CP-140 Aurora and the CH-149 Cormorants are in Greenwood, NS. The CH-148 Cyclones are in Shearwater, NS, The CH-147F Chinooks are in Petawawa, Ont. There are CC-138 Twin Otters are in Yellowknife. AETE, like all units in the Air Force, is facing a shortage of pilots. Recruiting multiengine pilots from Eastern Canada is a challenge for AETE, and a CC-130H Hercules pilot based in Winnipeg does not necessarily want to uproot his or her family to Cold Lake where his or her spouse would have limited options for employment, as well as restricted access to health care. “Although once people get to Cold Lake, they usually enjoy their time here,” said Grandmont. “It is a beautiful area.” AETE has also been losing personnel to private industry, which can offer better working conditions for experienced testers. Postmedia first revealed the proposal to move AETE in 2016. The plan first started under the Conservative government, but the Liberals continued with the relocation initiative. -With files from David Pugliese (Disclosure: The editor of the Cold Lake Sun is married to a member of AETE.) https://www.pinchercreekecho.com/news/local-news/aete-must-move-to-make-room-for-new-fighters-says-commanding-officer

    Cyber-warfare could be entering a new and alarming phase, ex-CIA analyst tells MPs

    Murray Brewster · CBC News Online attacks on Canada's financial system could become far more destructive as more militaries around the globe get involved in cyber operations, a security expert and former CIA analyst told a House of Commons committee Wednesday. Christopher Porter, the chief intelligence strategist for the cyber security company Fireeye, Inc., testified that as NATO countries share their expertise on how to defend against and defeat online threats, "major cyber powers outside the alliance" will likely do the same. The consequences, he said, could be dire. The West's imposition of sanctions on "some countries" has in the past been met with denial-of-service attacks on financial services websites, he said — attacks that have only been disruptive. "In the future, they may respond with destructive attacks aimed at permanently disabling financial services or altering data in ways that undermine trust in the global financial system, such as by delaying or impairing the trustworthy settlement of collateralized government debt," Porter said. "For countries sufficiently sanctioned and therefore increasingly outside that financial system anyway, there is little incentive not to do so during a confrontation." Where the threat comes from He did not name the countries he believes pose an imminent threat, but North Korea, Russia and Iran are widely known to possess sophisticated cyber capabilities and — in some cases — loose associations with groups of private hackers. The Commons public safety committee is studying security in the financial sector. Wednesday's hearing focused on online threats. "I am gravely concerned about the militarization of cyber operations," said Porter, who spent nearly nine years at the CIA and served as the cyber threat intelligence briefer to White House National Security Council staff. "(The) proliferation of cutting-edge offensive cyber power, combined with an increased willingness to use it with minimal blowback and spiraling distrust, has set the stage for more disruptive and destabilizing cyber events, possibly in the near future." The cyber espionage threat Canada faces is still "moderate," said Porter, but his organization has noted at least 10 groups from China, Russia and Iran that have targeted Canada in the last few years. His grim assessment was echoed by another private sector expert who appeared before the committee. Jonathan Reiber, head of cybersecurity at Illumio, an American business data center, said most of Washington's efforts to get everyone to step back from the cyber-warfare brink have gone nowhere. He also suggested that online militarization was inevitable. "Adversaries have escalated in cyberspace, despite U.S. efforts at deterrence," he said. The United States, Canada and other western nations must take a more aggressive stance to deter cyber aggression by "defending forward" and conducting offensive cyber operations to disrupt hacking, Reiber said. The Liberal government's defence policy, released in June 2017, gave the Canadian military permission to conduct those kinds of operations. "Nation states have the right to defend themselves in cyberspace just as they do in other domains," Reiber said. Mutual defence Determining the point at which a online attack provokes a real world military response is something that NATO and many western countries have been grappling with over the last five years. The alliance has a mutual assistance clause, known as Article 5, which requires NATO nations to aid an ally under attack. Liberal MP John McKay, head of the public safety committee, asked whether NATO's decision-making mechanisms are nimble enough to keep pace with cyber attacks. Porter said he believes the system is sound. The challenge, he said, is to get all allies on the same page. "I think a bigger issue is who is going to call for such a response and under what circumstances," he said. "In the States, I think, you're always waiting for a cyber Pearl Harbour destructive event." Such a massive attack is still less likely than a series of smaller events, he said, "a death by a thousand cuts" that might not rise to the level of provoking allies. https://www.cbc.ca/news/politics/cyber-warfare-could-be-entering-a-new-and-alarming-phase-ex-cia-analyst-tells-mps-1.5008956
