Third-Party App Risks in the Age of Infostealer Malware

In this article, we discuss possible causes for breaches and how to take measures against them. As organizations rely more on third-party apps for efficiency and scalability, they also open doors to new cyber risks--especially from infostealer malware.

Name of the Game: Infostealer Malware

Infostealers are a type of malware designed to capture sensitive information from infected systems, such as login credentials, payment data, and other authentication details. These threats operate quietly, often evading detection while collecting valuable data.

Infostealers typically enter systems through phishing emails, compromised websites, or malicious downloads. Unlike ransomware, which demands payment, infostealers aim to gather data that attackers can use or sell, making them particularly dangerous to organizations that rely on third-party platforms with broad permissions.

Notable Cases of Third Party Applications and Supply Chain Compromise

Airbus

The RedLine infostealer malware compromised a Turkish airline employee's system, resulting in the exposure of sensitive data from 3,200 suppliers. This breach highlights the risks of weak endpoint security within the supply chain, where adversaries target vulnerable systems to exfiltrate valuable organizational data.

Uber

Raccoon stealer malware bypassed Uber's two-factor authentication (2FA) by leveraging session hijacking techniques and escalating privileges to gain access to internal systems. This incident illustrates the vulnerabilities of 2FA when adversaries exploit underlying session management flaws and unauthorized privilege escalation to circumvent multi-factor protections.

AT&T and Ticketmaster (Snowflake Incident)

Third-party platforms like Snowflake are crucial for modern businesses, offering tools for data storage, analysis, collaboration, and cloud accessibility. These platforms help companies focus on core operations by streamlining processes and enabling seamless data sharing. However, their popularity makes them attractive targets for cyber criminals.

In 2024, AT&T experienced a breach involving infostealer malware deployed by hacker group UNC5537, which stole customer credentials and led to unauthorized access to sensitive data on a third-party cloud platform, likely Snowflake. This attack, part of a larger campaign that also targeted organizations like Ticketmaster, highlights the significant risks posed by third-party applications and supply chain compromises.
