Canada’s Oil and Gas Sector Faces Rising Cybersecurity Threats Amid Digital Transformation

 

Canada’s oil and gas sector, a vital part of its economy, contributes approximately $120 billion, or about 5% of the country’s Gross Domestic Product (GDP). This industry not only drives economic growth but also supports essential services such as heating, transportation, and electricity generation, playing a crucial role in national security. However, the increasing digital transformation of Operational Technology (OT) within this sector has made it more vulnerable to cyber threats, according to a report by the Canadian Centre for Cyber Security.

A survey conducted by Statistics Canada revealed that around 25% of all Canadian oil and gas organizations reported experiencing a cyber incident in 2019. This is the highest rate of reported incidents among all critical infrastructure sectors, highlighting the urgent need for improved cybersecurity measures in Canada. While the digital transformation of OT systems enhances management and productivity, it also expands the attack surface for cyber actors, exposing these systems to various cyber threats.

The Canadian Centre for Cyber Security's report indicates that medium- to high-sophistication cyber threat actors are increasingly targeting organizations indirectly through their supply chains. This tactic enables attackers to gain valuable intellectual property and information about the target organization’s networks and OT systems. The reliance of large industrial asset operators on a diverse supply chain—including laboratories, manufacturers, vendors, and service providers—creates critical vulnerabilities that cyber actors can exploit to access otherwise protected IT and OT systems.

The report emphasizes that cybercriminals driven by financial gain pose the most significant threat to the oil and gas sector. Business Email Compromise (BEC) schemes and ransomware attacks are particularly prevalent. Although BEC is more common and costly, ransomware remains a primary concern due to its potential to disrupt the supply of oil and gas to customers.

The evolving cybercriminal ecosystem, including ransomware-as-a-service (RaaS) models, allows even less skilled attackers to launch sophisticated attacks, resulting in an increase in successful incidents targeting the sector. The report cites the Colonial Pipeline ransomware attack in May 2021 as a stark example of the potential consequences of such cyber incidents. This attack forced the shutdown of a major fuel pipeline in the U.S., leading to significant disruptions, panic buying, and price spikes. Similar incidents could occur in Canada, jeopardizing the supply of essential products and services.

Financial Implications of Data Breaches

The report also highlights the financial implications of cyber threats. The cost of a data breach can vary significantly, with estimates suggesting it can reach millions of dollars depending on the organization's size and nature. The potential for disruption or sabotage of OT systems poses a costly threat to owner-operators of large OT assets, impacting national security, public safety, and the economy.

The Canadian Centre for Cyber Security notes that the oil and gas sector attracts considerable attention from financially motivated cyber threat actors due to the high value of its assets. Cybercriminals target not only operational systems but also valuable intellectual property, business plans, and client information. Protecting these assets is crucial, as the disruption of operations could have far-reaching consequences.

In light of these threats, the report urges organizations within the oil and gas sector to prioritize cybersecurity investments and adopt a proactive approach to risk management. Continuous training and awareness programs for employees are essential to mitigate risks associated with human error, a significant factor in successful cyber attacks.

The Canadian Centre for Cyber Security stresses the need for collaboration between public and private sectors to combat cyber threats effectively. By sharing information and best practices, organizations can better prepare for and respond to cyber incidents.

Overall, the findings from the Canadian Centre for Cyber Security highlight the pressing need for enhanced cybersecurity measures within Canada’s oil and gas sector. With cyber threats on the rise, it is imperative for organizations to take proactive steps to safeguard their operations and ensure the resilience of this critical infrastructure. The time to act is now, as the stakes have never been higher in the fight against cybercrime

Cybersecurity Threats Fickle Stealer Infostealer Malware Safety Security

New Infostealer 'Fickle Stealer' Targets Sensitive Data Using Multiple Distribution Methods

 

Security experts are raising alarms about a new infostealer named Fickle Stealer, which is being disseminated through various techniques across the internet. Fickle Stealer engages in typical malicious activities, such as stealing sensitive files, system information, browser-stored files, and cryptocurrency wallet details. However, what sets Fickle Stealer apart is its construction using the Rust programming language.

"Beyond targeting popular applications, this stealer searches for sensitive files in the parent directories of common installation paths to ensure thorough data collection," stated security researcher Pei Han Liao. "It also fetches a target list from the server, adding flexibility to Fickle Stealer's operations."

According to cybersecurity researchers from Fortinet FortiGuard Labs, Fickle Stealer employs four distinct distribution methods: a VBA dropper, a VBA downloader, a link downloader, and an executable downloader. Some of these methods utilize a PowerShell script that bypasses User Account Control (UAC) mechanisms. This script also transmits system information, such as the device's location (country and city), IP address, operating system version, computer name, and username, to a Telegram bot.

Infostealers are among the most prevalent and disruptive forms of malware, second only to ransomware. They enable cybercriminals to access sensitive services, including banking accounts, social media profiles, and corporate platforms. With access to cryptocurrency wallet data, hackers can transfer funds to their own wallets, effectively stealing any available money. Furthermore, infostealers allow criminals to access email inboxes, leading to phishing attacks, impersonation, identity theft, and potentially ransomware attacks on corporate IT systems.

Securing devices against infostealers involves the same precautions as defending against other types of malware. Users should avoid downloading and running suspicious files and thoroughly verify email attachments before opening them. By adhering to these practices, individuals and organizations can better protect their sensitive data from cyber threats.

YouTube Emerging as a Hotspot for Cyber Threats: Avast Report

 

YouTube has become a new battleground for cybercriminals to launch phishing attacks, spread malware, and promote fraudulent investment schemes, according to a recent report by Avast, a leading security vendor.

Avast's researchers highlighted the use of tools like Lumma and RedLine in executing phishing attacks, creating scam landing pages, and distributing malicious software. YouTube functions as a traffic distribution network, guiding unsuspecting users to these harmful sites, thus facilitating various levels of scams.

The platform is also experiencing a surge in deepfake videos, which are used to mislead viewers with hyper-realistic but fake content, thereby spreading disinformation. Avast discovered multiple high-subscriber accounts, each with over 50 million followers, that were compromised and repurposed to disseminate cryptocurrency scams utilizing deepfake technology. These fraudulent videos often feature fake comments to deceive viewers further and include links to malicious sites.

Researchers identified five primary methods through which YouTube is exploited by cybercriminals. These include sending personalized phishing emails to YouTube creators, proposing fake collaboration opportunities to gain trust and eventually send malicious links. Additionally, attackers embed malicious links in video descriptions to trick users into downloading malware. They also hijack YouTube channels to spread other threats, such as cryptocurrency scams.

Moreover, cybercriminals exploit reputable software brands and legitimate-looking domains by creating fraudulent websites filled with malware. They produce videos that use social engineering tactics, guiding users to supposedly helpful tools that are actually malicious software in disguise.

Avast attributes its advanced scanning technology to protecting over 4 million YouTube users in 2023 and around 500,000 users in the first quarter of this year alone.

Trevor Collins, a network security engineer at WatchGuard, stresses the importance of educating employees and security teams about these threats. 

"Regular education is essential. Make people aware that there are scammers out there doing this," Collins says. "In addition, train and reassure them that it's OK to notify either their security team or other people within the company if they've gotten an unusual request — for instance, to provide login credentials, move money, or go buy a bunch of gift cards — before acting on it."

Critical Windows Event Log Vulnerability Uncovered: Enterprise Security at Risk

 

In a recent discovery, cybersecurity researchers have identified a critical zero-day vulnerability posing a significant threat to the Windows Event Log service. This flaw, when exploited, has the potential to crash the service on all supported versions of Windows, including some legacy systems, raising concerns among enterprise defenders. 

Discovered by security researcher Florian and reported to Microsoft, the zero-day vulnerability is currently without a patch. The Windows Event Log service plays a pivotal role in monitoring and recording system events, providing essential information for system administrators and security professionals. The exploitation of this vulnerability could result in widespread disruption of critical logging functions, hindering the ability to track and analyze system activities. 

In PoC testing, the team discovered that the Windows Event Log service restarts after two crashes, but if it experiences a third crash, it remains inactive for a period of 24 hours. This extended downtime poses a considerable risk, as many security controls rely on the consistent functioning of the Event Log service. The fallout includes compromised security controls and non-operational security control products. This vulnerability allows attackers to exploit known vulnerabilities or launch attacks without triggering alerts, granting them the ability to act undetected, as outlined in the blog. 

During the period when the service is down, detection mechanisms dependent on Windows logs will be incapacitated. This grants the attacker the freedom to conduct additional attacks, including activities like password brute-forcing, exploiting remote services with potentially destabilizing exploits, or executing common attacker tactics such as running the "whoami" command, all without attracting attention. 

While the vulnerability is easily exploitable locally, a remote attacker aiming to utilize the PoC must establish an SMB connection and authenticate to the target computer. Configuring Windows to prevent this attack without completely disabling SMB poses a challenge, given its role in various network functionalities like shares and printers, according to Kolsek. Internet-facing Windows systems are unlikely to have open SMB connectivity, reducing the likelihood of remote exploitation. 

The vulnerability proves advantageous for an attacker already present in the local network, especially if they have gained access to a low-privileged user's workstation. As a temporary solution until Microsoft issues a patch, users can apply a micro patch provided by Acros through the 0patch agent, tailored for multiple Windows releases and server versions. This helps mitigate potential real-time detection issues linked to the Event Log service's disablement.
