#1: Cyber Assault Forces Southwestern Ontario Hospitals to Rebuild Networks
A sophisticated cyberattack in October struck five hospitals in southwestern Ontario, compelling them to undertake a complete reconstruction of their networks.
The hospitals, including Windsor Regional Hospital, Hotel-Dieu Grace Healthcare, Erie Shores HealthCare, Bluewater Health, and Chatham-Kent Health Alliance, released a statement through their IT provider, TransForm, affirming the impact on all clinical and non-clinical systems reliant on a secure network.
In response to expert advice, the hospitals opted for the cautious approach of rebuilding their networks entirely. The statement detailed the affected systems, encompassing patient records and history, medication lists, pre-admission work-ups, and reports from other professionals involved in patient care.
This incident aligns with the broader trend of healthcare being consistently targeted by cyberattacks, with unauthorized access in hospitals escalating by 162% since 2019.
#2: India-Linked Hacker Group Targets Military and Parliament Websites in Major Canadian Cyberattacks
A hacker group based in India claimed responsibility for a series of cyberattacks targeting military and parliamentary institutions in Canada. Despite the assertion, Canada's signals intelligence agency suggested that these attacks were more of a "nuisance" nature, with no apparent compromise of private information. The focus of the attacks was on government-controlled institutions rather than the core infrastructure supporting federal departments and agencies.
In September, the Canadian Armed Forces reported a temporary unavailability of their website to mobile users, quickly resolved within a few hours. Although the attack impacted various pages on the House of Commons website, House of Commons systems responded as planned, protecting the network and IT infrastructure.
#3: Suncor Energy Faces Cybersecurity Incident Impacting Petro-Canada Gas Stations Nationwide
Calgary-based Suncor Energy joined the ranks of oil companies facing cybersecurity incidents in 2023, as social media users reported disruptions at Petro-Canada gas stations and issues accessing the company's car wash services.
While Canada has not experienced large-scale cyberattacks on domestic oil and gas companies, cybersecurity experts have long warned of the industry's attractiveness to both financially motivated cybercriminals, including ransomware attackers, and state-sponsored hackers seeking geopolitical disruption. The incident at Suncor Energy underscores the persistent threat faced by the country's energy sector in the ever-evolving landscape of cyber threats.
#4: Midnight Blizzard's Microsoft Teams Assault Through Mass Social Engineering
In August, Microsoft Threat Intelligence sounded the alarm on a targeted social engineering campaign orchestrated by the Midnight Blizzard hacker group, also known as NOBELIUM, specifically using Microsoft Teams as their battleground.
Operating under the guise of tech support entities within previously compromised Microsoft 365 tenants, Midnight Blizzard employed a clever tactic: sending messages over Teams to unsuspecting users. This cunning approach allowed them to pilfer credentials, exploiting the platform's vulnerabilities and sidestepping multi-factor authentication (MFA) prompts.
While this calculated campaign affected fewer than 40 organizations globally, it did include targets within Canada. To thwart potential future attacks, organizations were urged to take the following steps:
- Scrutinize the Microsoft advisory, actively seeking indicators of compromise to detect related activity.
- Conduct Employee Awareness Training focused on phishing, coupled with established procedures for handling phishing attempts received by employees or key stakeholders.
- Implement phishing-resistant MFA solutions, such as FIDO2 security keys, Windows Hello, and Certificate-Based Authentication.
- Enforce rigorous management of administrative privileges.
- Strengthen business continuity planning to ensure resilience in the face of cyber threats."
#5: Indigo Faces a $50M Blow, Mostly Attributed to Post-Cyberattack Recovery Time
In a significant setback, Indigo reported a staggering loss of $50 million in its latest fiscal year, primarily stemming from a high-profile cyber breach.
The TSX-listed company disclosed its financial results for the most recent quarter and full fiscal year up to April 1st, 2023, unveiling that the renowned book retailer experienced a $4.6 million (0.4%) dip in revenue compared to the previous year, totaling $1.058 billion.
Despite a marginal increase in merchandise sales by $4.6 million (0.5%) to $1.015 billion, the aftermath of their infamous cyberattack in February cast a long shadow. The massive breach incapacitated Indigo's stores, rendering them incapable of processing debit or credit card transactions for several days. This, in turn, wiped out online sales for nearly a month.
Indigo's financial woes underscore the critical importance of proactive investments in cybersecurity, emphasizing the need to fortify defenses before falling victim to an attack. This rings especially true for cyber insurance, with a noteworthy 48% of SMBs opting to purchase it only post-breach."
#6: Air Canada Faces Security Breach with Employee Data Exposure
In a recent revelation, prominent transportation company Air Canada disclosed a security breach that granted unauthorized access to the "personal information of some employees and certain records."
While details regarding the extent and timing of the breach were limited in the company's statement, it emphatically reassured that no customer information was compromised in this incident. Air Canada swiftly responded to the breach by implementing measures to mitigate its impact. The company has taken proactive steps, reaching out to the affected parties of the data leak and notifying relevant authorities.
In tandem with this breach, the Canada Border Services Agency (CBSA) acknowledged a distributed denial-of-service (DDoS) attack, causing disruptions in connectivity that affected check-in kiosks and electronic gates across multiple airports nationwide.
During this period, a hacking group with alleged ties to Russia claimed responsibility for several attacks targeting key Canadian government organizations, including both the CBSA and the Canadian Air Transport Security Authority.
The confluence of these incidents underscores the multifaceted challenges faced by critical entities in the transportation sector. As cyber threats continue to evolve, it becomes imperative for organizations like Air Canada to remain vigilant, continually fortifying their cybersecurity measures to protect both employee and customer data from the ever-present risk of unauthorized access and disruptive attacks.
