Discover crucial hazards that could affect your establishment and the malevolent culprits steering them from Cybersixgill’s team of experts in security threats. Each narrative illuminates clandestine operations, the individuals behind the threats, and the reasons for vigilance, as well as measures to mitigate risks.
In a world increasingly interconnected, infiltrations through supply chains have arisen as a daunting peril, jeopardizing not only singular organizations but the wider digital environment. The intricate network of relationships among businesses, notably software and IT providers, offers fertile ground for malefactors to exploit susceptibilities. By honing in on a single vulnerable link within the supply chain, threat actors can gain illicit entry to confidential information and carry out malevolent deeds with grave repercussions on multiple organizations, ranging from data breaches and monetary losses to widespread disruption and harm to reputation.
Gaining insight into the essence, implications, and mitigation approaches of supply chain attacks is imperative for fortifying cybersecurity defenses and guaranteeing the safety and resilience of the totality of the third-party network.
Rising Peril of Supply Chain Incursions
Supply chain assaults target the networks, systems, and procedures of an organization’s third-party vendors and suppliers, empowering malevolent actors to infiltrate and undermine the infrastructure of the ultimate victim. Following entry into a system, threat actors can implant harmful code, pilfer sensitive data, or disrupt operations, setting off a chain reaction within the supply chain. A breach at one organization or link within the supply chain can yield widespread repercussions and jeopardize the security of numerous entities. With this knowledge, perpetrators increasingly set their sights on the supply chain to gain a foothold and infiltrate the systems of organizations.
According to findings from Capterra, 61% of U.S. businesses were directly affected by a software supply chain assault in the 12 months leading up to April 2023. Our investigations reveal an uptick in the number of subterranean posts by cybercriminals advertising access to networks of service providers (comprising IT services, cloud services, HR solutions, and other services) over recent years. In 2023, there were approximately 245,000 software supply chain attacks, resulting in losses of $46 billion for businesses. This figure is predicted to surge to $60 billion by 2025, as threat actors increasingly target service providers, their clients, and associated third parties.
Objectives & Motivations of Attackers
The motives behind these assaults are multifaceted. The primary aim is unauthorized entry to specific systems or networks, which are more vulnerable when targeted through the supply chain. Such attacks also empower threat actors to attain greater dividends as they can have an impact on the intellectual property, financial information, customer data, and other confidential data of multiple organizations, which can be exploited for profit or utilized for competitive advantage.
While financial gain serves as a pivotal motivator for many cybercriminals, their objectives can extend to cyber espionage, political motives, or the pilfering of trade secrets and intellectual property. State-backed actors might seek access to classified intelligence or national security secrets, whereas competitive industries could encounter threats directed at exclusive research and innovations.
Infiltration Techniques
Perpetrators employ diverse modalities to execute supply chain attacks, as delineated below.
Breached Accounts
Malevolent actors frequently exploit the credentials of trusted vendors to access interconnected systems of target organizations, leveraging entrenched trust to circumvent conventional security protocols. These credentials can be obtained through various means or procured on illicit digital forums. For instance, Cybersixgill identified a post where a threat actor vendored access to the networks of a major Chinese cloud provider, impacting clients such as Ferrari and Audi.
Such breaches can lead to data theft, fraud, malware propagation, and ransomware assaults. Additionally, compromised providers can furnish doctored software to clients, resulting in harm to reputation, financial setbacks, legal entanglements, and operational interruptions.
Malware Insertion
Attackers also infuse malignant code or malware into legitimate components to incite a widespread chain of infection. For instance, in April 2024, a backdoor was unearthed in the data compression utility XZ Utils, enabling malefactors to gain unauthorized entry and execute remote code operations. This malevolent code affected various commonly used Linux distributions, including Kali Linux, Fedora, Debian, and Arch Linux. The backdoor was surreptitiously introduced by an individual who had gained the trust of the XZ Utils project maintainers over a span of two years, culminating in widespread damage.
Exploitation of Vulnerabilities
Capitalizing on vulnerabilities in software, hardware, or procedures is also an efficacious strategy to execute supply chain assaults and gain unauthorized entry, compromise systems, and propagate malevolent deeds. In June 2023, three critical SQL injection vulnerabilities were uncovered in Progress Software’s MOVEit Transfer platform, impacting roughly 1,700 organizations. The Cl0p ransomware syndicate exploited these vulnerabilities in a widespread assault, targeting entities such as Zellis, British Airways, the BBC, and the Minnesota Department of Education. This led to illicit access to sensitive information, including personal and financial particulars.
Insights from Previous Incidents
Prominent supply chain attacks, such as those on SolarWinds, Kaseya, and NotPetya, underscore the potentially devastating nature of these breaches. The SolarWinds assault entailed implanting a backdoor within software updates, which were subsequently disseminated to thousands of clients, encompassing government agencies and major corporations. This incident accentuated the necessity of stringent security measures for software supply chains and the imperative for uninterrupted vigilance and swift response capabilities.
Risk Mitigation Strategies
Given the dire implications of supply chain assaults, organizations’ SOC and threat-hunting teams must adopt proactive strategies to mitigate risks. Equipping teams with the right tools, intelligence, and context aids in comprehending the specific threats facing their organization.
The Third-Party Intelligence module by Cybersixgill furnishes advanced cyber threat intelligence from a plethora of sources, furnishing organizations with crucial insights into the cybersecurity vulnerabilities of their suppliers. This enables security teams to:
- Anticipate supply chain threats
- Continuously evaluate the security stance of third parties to minimize risks
- Report threats and propose recommended remedial actions to impacted vendors
- Conduct research on mergers and acquisitions before agreements are finalized
Conclusion
In the dynamically shifting cyber threat landscape, safeguarding a secure supply chain is not merely a tactical priority but an intrinsic necessity for upholding the integrity and dependability of digital operations.
The escalating peril of supply chain attacks mandates heightened awareness and robust security tactics from all stakeholders. As business networks grow more interconnected, the vulnerabilities within supply chains become increasingly discernible and exploitable. Organizations must implement comprehensive security measures, continually assess their relationships with third parties, and stay abreast of the latest threats to fortify their digital networks.
