Hospitals far more vulnerable to cyberattacks due to health crisis

If this is not the first thing that crosses the mind in this time of health crisis, it is the fact that hospitals are now the targets favoured by cyber criminals.

Cyber criminals looking for ways to make money increasingly targets health centers and other institutions with ransomware. These latter accounts for the fact that hospitals are overwhelmed by the ever-increasing number of patients every day, will not dare to refuse to pay the ransoms demanded. This is to avoid dramatic consequences that could affect the lives of patients. However, at the beginning of the health crisis, some cyber criminals had promised not to attack health facilities. One wonders what the state of this promise is today.

This situation is quite complicated. From the United States and Canada to Europe, almost every week hospitals and health centres are targeted and attacked.

Last week, the FBI, the U.S. Federal Police, issued a pretty strong alarm. In collaboration with the Department of Health and the Department of the Interior, the Federal Police officially declared an "imminent cybercriminal threat against U.S. hospitals and health service providers." In the aftermath, the U.S. authority urges health facilities to "take prompt and appropriate precautions to protect their computer networks."

For this problem of computer threats, the trend and much more on the side of ransomware. The malware that allows cyber criminals to encrypt access to their targets' information systems and data. Demanding in return the payment of a certain amount of money in exchange for the decryption keys.

In such cases, some targets agree to cooperate and pay the ransom demanded. But not everyone does. For example, the University of Vermont Hospital in the United States, recently stated that it was hit by a similar attack, it would work accordingly with the authorities to contain it. "A now confirmed cyberattack has affected some of our systems with varying impacts on patient care. means the center.

In recent weeks, nearly 400 hospitals have reportedly been victims of an illegal intrusion into their information systems. They are located in the United Kingdom and the United States based on data collected by Cybersecurity expert Daniel Dos Santos at Forescout. "Interrupting care means people are going to die," dos Santos says.

Unfortunately, health care facilities cannot afford to block the computer system for quite a long time. This means that it will have to be done in an analogous way, "which can cause major slowdowns," the Forescout specialist adds.

Unfortunately, the health sector's computer systems are particularly vulnerable. Indeed, it generally uses devices such as scanners that are considered to be the most sensitive point for the security of the network as a whole. The problem is that these tools typically use unsecured channels for data transmission. A boon for cyber criminals. The proof, Mr. dos Santos discovered in a recent report conducted during a study conducted by his company of caps belonging to nearly 3 million American patients. Data that is "unprotected and accessible to anyone who knows how to search."

In early October, Canadian authorities warned all institutions against attacks by the Ryuk ransomware. "Affecting multiple (public) entities, including municipalities, health and safety organizations in Canada and abroad." "The problem with extortion software is that it's getting worse. We desperately have to find a solution," says Brett Callow, a specialist at Emsisoft, a company specializing in computer security. He therefore advises a strict ban on the payment of ransoms. Because "these types of attacks exist because they are profitable. If the money tap was stopped, (they) would stop and hospitals would no longer be at risk," he notes.

Hacking with pro-Islamist messages

For some time now, there has been a wave of anti-French sentiment in the Muslim world.

Especially after some of the remarks made by French President Emmanuel Macron. This situation also has an impact on computer security. Indeed, several French sites were targeted by various computer attacks that aimed to disfigure their interface. The hackers managed to control nearly 10 websites whose home pages were purely at their mercy.

It all starts exactly on Sunday. The Muslim world is angry at the French president and all of France in a way. Illicit attacks have been observed by the national system of assistance to persons targeted by cyber-malicious actors. The organization has spotted several disfigurements of French platforms and believes that this is growing, "by hackers dissatisfied with the president's words on freedom of expression and the caricatures of Muhammad, after the assassination of Professor Samuel Paty. ».

The Cybermalveillance.gouv platform then made a definitional approach to this type of computer hacking, it must be admitted is quite special. It consists of "demonstrating a takeover of the site and making it known with different objectives: the search for notoriety, the political or ideological claim, the direct damage to the image of the site, and/or the theft of sensitive information. ». The organization will give some rules to follow in order to be able to protect against this act of cyber malice. For example, regular updating of computer systems and software.

At the moment no large-scale damage has been observed as the targeted websites are in relation to their level of security. "Often, disfigured sites are already 'holed' and could be compromised with just a few clicks," explained cyberwar hacker Adrien Jeanneau in an interview with online media outlet Numérama. 

The websites of the Parisian club Paris FC, one of the residents of the 2nd division of the French championship. The club would have been targeted because of its ideological criteria. It should be noted that the president of the club, Pierre Ferracci, is quite close to President Emmanuel Macron. "You have insulted our prophet and we will avenge this unless you apologize to the Muslims. "Cybercriminals who wrote the attack on the homepage. According to some reports he is of Bangladeshi origin. However, an important point to be served, the Muslim state of Bahrain a 20% owner of the Parisian club.

In the background, there have not been many large group apartment websites. In particular, they were sites with little audience or a confidential audience. Among other things, small's campsites of French town halls or deputies.

The messages relayed by the hackers according to Europe 1 are: "Victory for Mohammed, victory for Islam and Death to France and a montage depicting Emmanuel Macron climbed into a pig were displayed in place of the home pages."

"In 2015, after the attacks on Charlie Hebdo and Hyper Cacher, thousands of French sites, including those of local authorities, had already been disfigured," Cyberwaris noted. Several other campaigns are visible on the internet targeting President Macron and France. This can be said clearly in one of his messages; "You have freedom of expression and we are free to behead. ».

Hackers on the attack on information systems

It has been brought to the public attention that the Jewish General Hospital in Montreal was affected by a computer attack deemed disturbing.

The cyberattack was reportedly aimed at stealing medical data.

In recent times, Quebec has been plagued by a wave of computer attacks that affects almost all sectors of activity, particularly the health and public transport sector. Whether it's hospitals in health centres, police facilities or public transport, hackers are literally on the attack.

The Jewish General Hospital in Montreal had to urgently disconnect its entire computer network last Wednesday. The same is true of the CIUSSS in the West Centre of the Island of the Quebec city. The urgency was reported when it was observed that an intrusion was actually directed at the health data. Servers, Internet access, computers or any other connected machine had to be disconnected from me. To prevent the intrusion from having a slightly broader consequence. "We are practically an isolated island in the entire health care system," CIUSSS CEO Dr. Lawrence Rosenberg said at a press briefing on Thursday.

Of course such a situation with the decision that followed to create a slowdown in important services. Management acknowledges this fact, but notes that the negative effects are limited at this time. "There may be some service withdrawals, but it's really minimal. Screening centres work as usual," said Francine Dupuis, deputy CEO of the health organization. "There was no ransom or ransom demand that was made, since we cut the problem at its source. ». Says ciUSSS deputy manager of the West Centre of the Island of Montreal.

For now, the agency says it can't elaborate on any link between this intrusion and the wave of ransomware computer attacks that nearly half a dozen U.S. health facilities, particularly in New York and California, are experiencing these days. It should also be noted that 3 Ontario hospitals hospitals have been affected by similar cyber attacks. According to a recent Washington Post article, the cybercriminals behind all these attacks are active from Eastern Europe and communicate in Russian.

Currently, several teams are searching for these computer attacks. In particular, the cybersecurity team seconded by the Department of Health and Social Services, specialists from the Royal Canadian Mounted Police and the SQ, a technician seconded by Microsoft. They want to know everything that has happened at the level of Montreal's health institutions and find ways to restore disconnected systems sustainably and safely. According to ciUSSS vice-manager Dr Dupuis, the operation will take "a few days (…) We don't know what they're going to find, or how long it's going to take for them to find it."

"It may be a coincidence, but there is every reason to believe that what is happening in Quebec's health care system is linked to the wave of attacks we see in the United States," says Alexis Dorais-Joncas, a computer security researcher and team leader at ESET, a cybersecurity firm. "If that is the case, it is unlikely that the initial compromise occurred on Wednesday. Rather, it is the kind of attack where malware spreads through networks over time. Hackers are gradually gaining administrator privileges," he adds. Regarding the Ryuk ransomware, he notes that: "Since 2019, this ransomware has been increasingly used to attack large companies or organizations. Hackers carry out a three-phase attack to infiltrate computer networks and encrypt all the data in them. They then claim a large sum from the administrators, in exchange for which they usually release the data. ».

Investigations continue for the time being.

Canadian and U.S. hospitals targeted by wave of large-scale computer attacks

Since the beginning of the week, the computer systems of several U.S. and Canadian hospitals have faced a cyberattack campaign.

While no concrete relationship has been established between these various computer attacks, the hypothesis of a mass, well-organized attack is the main route of the authorities and specialists.

"It may be a coincidence, but there is every reason to believe that what is happening in Quebec's health care system is linked to the wave of attacks we see in the United States … If so, it is unlikely that the initial compromise occurred on Wednesday. Rather, it is the kind of attack where malware spreads through networks over time. Hackers are gradually gaining administrator privileges," notes Alexis Dorais-Joncas, a computer security researcher and team leader at ESET.

It is practical to note that these cyberattacks target not only hospitals but several other health-related and non-health-related institutions. For example, in Quebec, the Ministry of Health was also the victim of a ransomware attack. Because indeed the attacks are indeed and ransomware.

In other words, we are talking about a large-scale attack. According to the US authorities, the threat is not only growing but also imminent. One more problem to deal with in the midst of the Covid-19 pandemic. As if cyber criminals had decided to take advantage of this moment to facilitate their actions.

Several investigations are still on both the U.S. and Canadian sides. As a result, several government structures and institutions are involved in clearing up this computer scourge. The Health Sector Cyber Security Operational Centre is deploying a package of measures to best limit the negative impact of this campaign of ransomware cyberattacks.

In another sense, some even refer to a global campaign. According to an email from the Ministry of Health's Cyber Defense Operational Center, the attacks are very well coordinated, and in less than 24 hours several hospitals have been affected. Some health institutions such as the CIUSSS of the West Centre of the Island of Montreal have disconnected all of their devices and servers connected to the Internet. All external remote access has been removed.

The consequences of such a situation are really important. For example, there are difficulties in accessing information for medical test results, particularly those related to covid-19. In the case of urgency, the information continues to be transmitted via the computer, even if this is not really advisable. In an internal memo, Laurence Rosenberg, CEO of CIUSSS at the West Centre of the Island of Montreal, wrote, "We do not believe that information about patients or staff has been accessed. ».

But it must also be said that this wave of cyberattacks is not limited to the health sector. Indeed, the Montreal transportation company was hit by a ransomware. On the Quebec security side, a similar cyber attack was also observed. In the United States all institutions are on alert. The threat is considered imminent is growing.

"Same problem in the United States. U.S. federal agencies warned the health care system on Wednesday that such attacks are a growing and imminent threat.The Cybersecurity and Infrastructure Security Agency (CISA) says in an opinion issued during the week that all structures in the health sector must take a number of measures to protect themselves because the situation is serious. radio Quebec reports.

The U.S. cybersecurity agency says U.S. hospitals that are under attack have been attacked through the Ryuk ransomware. For Canadian hospitals, there is no confirmation on this side at this time. The modus operandi of cyber criminals is either simply to paralyze the system and encrypt access to data and the computer network. CISA also states that it is through another malware, Trickbot, that the Ryuk ransomware is deployed.

With regard to the relationship that may well exist between the attacks on U.S. and Canadian hospitals, the outcome of a thorough investigation is waited.

Digital transformation firm Sopra Steria was the victim of an attack

The company after suffering a computer attack announced soon to return to normal within a few weeks.

The IT service group made the statement on Monday, six days after it publicly announced it had been targeted by a large-scale computer attack.

This did not interfere with the proper operation of the business. "The return to normalcy throughout the group will take a few weeks," Sopra Steria said in a recent statement. The group said the "progressive and secure restart" of its information system had begun on Monday.

In other words, according to the IT service company, the discovery of the cyberattack, several "security measures immediately implemented," which allowed the company "to contain the spread of the virus to a limited part of the group's facilities and to preserve its customers and partners," the company's spokesman said in the statement.

At this time, the company maintains that it has not yet "found any data leakage or damage to its customers' information systems."

According to the company, the malware used to infiltrate its computer network is a famous ransomware: "This is a new version of the Ryuk 'ransomware' hitherto unknown to antivirus vendors and security agencies." Ransomware called ransomware is a malicious computer program that is used to take a computer system or network hostage, criticizing the access and data contained in that system, and then demanding payment of the ransom in exchange for the decryption keys. A scourge that has been in vogue for some time in the cybersecurity sector. Unfortunately, many companies are continually affected by these types of cyberattacks. Last spring it was the optical specialist Essilor and the group specializing in the analysis service Eurofins last year went through this cyberattack box. The list of victims is growing. From the Norwegian aluminium production company Norsk to the French agri-food group Fleury Michon through the French construction group Bouygues construction.

At this time the extent of the attack suffered by Sopra Steria has not yet been determined as a company has not been made on the subject.

The trend continues. Businesses seem to be unduitable for this problem. The number of companies regardless of the sector affected by ransomware this year continues to grow. Authorities are continuing to investigate the true origin of his computer attacks. Even if it seems inconclusive, there is a slim chance of being able to trace it back to cybercriminals. So the advice remains the same. Practice the right uses for digital. Continue to raise awareness among employees to close the door to cybercrime as much as possible. Update its applications and operating system and back up its data.
