Cyberattacks Strike North American Transportation Companies Using Lumma Stealer and NetSupport Malware

Transportation and logistics companies across North America have fallen victim to a new wave of cyberattacks that have left them vulnerable to a range of malicious software. Recent reports from cybersecurity firm Proofpoint reveal that cybercriminals are leveraging a phishing campaign to target these industries, deploying a variety of information stealers and remote access trojans (RATs), including the notorious Lumma Stealer and NetSupport Manager malware.

These sophisticated attacks, which began in May 2024 and have continued into late August, highlight the increasing threat faced by critical infrastructure industries, including transportation, which are essential to the functioning of the global supply chain.

Phishing Campaign Exploiting Compromised Email Accounts

The attackers behind this campaign have utilized compromised legitimate email accounts belonging to transportation and shipping companies to inject malware into ongoing email threads. This tactic has proven to be particularly effective, as it lends legitimacy to the malicious emails, making it harder for recipients to detect the fraudulent nature of the communication. According to Proofpoint, as many as 15 email accounts have been breached and used as part of this ongoing attack.

Though the exact method by which these accounts were compromised remains unclear, it’s evident that the attackers are well-organized and sophisticated. The phishing emails typically contain .URL attachments or links to Google Drive, which lead to malicious files that activate once opened by unsuspecting users. The malware, once triggered, uses Server Message Block (SMB) to download additional payloads, further infiltrating the victim’s system.

Lumma Stealer, NetSupport Manager, and Evolving Tactics

Initially, from May to July 2024, the attackers predominantly relied on Lumma Stealer, StealC, and NetSupport Manager to carry out their attacks. Lumma Stealer is particularly dangerous as it is designed to exfiltrate sensitive information such as user credentials, banking details, and other personal data. NetSupport Manager, while initially a legitimate remote access tool, has been repurposed by the attackers as a trojan to take full control of the victim’s system remotely.

In August 2024, the cybercriminals updated their methods, using new infrastructure and delivery techniques. They also introduced new malware payloads, including DanaBot and Arechclient2, increasing the complexity and potential damage of their attacks. These new tactics make the threat even more dangerous, as they are designed to evade detection by conventional security systems.

One particularly concerning element of this new attack vector is the use of a method known as ClickFix. Victims are tricked into pasting a Base64-encoded PowerShell script into their terminal, initiating the download and installation of the DanaBot malware. This method exploits human error, preying on the victim’s trust in the malicious emails, which often impersonate well-known transportation management software providers such as Samsara, AMB Logistic, and Astra TMS.

Impact on the Transportation Industry

The transportation and logistics sectors have long been attractive targets for cybercriminals, given the critical role they play in the global economy. By disrupting operations or stealing sensitive data, cybercriminals can cause significant financial and operational damage to businesses. These industries rely on seamless coordination and communication, making any cyberattack particularly devastating.

The latest attack campaigns, focusing on companies involved in freight operations and fleet management, suggest that the attackers conduct extensive research on their targets, ensuring their phishing emails appear legitimate and relevant to the recipient. This targeting method increases the likelihood of success, as the victims are more likely to engage with the malicious content.

According to Proofpoint, the attackers behind this campaign may be financially motivated, seeking to steal valuable data that can be sold on dark web marketplaces. However, some researchers suggest that the evolving tactics and the introduction of espionage-related malware like RomCom RAT indicate that there may be broader motivations at play, such as espionage or sabotage.

Emerging Malware Threats: A Growing Concern

In addition to Lumma Stealer and NetSupport Manager, the transportation sector is facing a wave of emerging malware strains. These include Angry Stealer, BLX Stealer, and Gomorrah Stealer, among others. These new variants are designed to steal various types of sensitive data, ranging from login credentials to credit card information and cryptocurrency wallets.

Furthermore, the discovery of RomCom RAT—a sophisticated remote access trojan used in targeted espionage campaigns—adds another layer of complexity to the threat landscape. RomCom RAT allows attackers to execute commands, download additional malware, and even control the victim’s system entirely. Unlike earlier versions of the malware that were linked to ransomware campaigns, RomCom RAT appears to be focused on gathering intelligence, possibly indicating a shift toward cyber-espionage activities.

The threat posed by these new malware variants cannot be overstated, as they have the potential to disrupt critical infrastructure and steal invaluable data, leaving companies vulnerable to further attacks and financial losses.
