Uber Freight keeps on trucking after extortion crew breaks in

Uber Freight says it is investigating a "data security incident" days after the Helix extortion group listed the company on its data leak site on August 6. Helix claims to have stolen nearly 1 million files from mailboxes, OneDrive accounts, the accounts receivable department, and other repositories. An Uber Freight spokesperson told The Register that the incident was under investigation but had not disrupted the company's daily operations. "We are investigating a data security incident involving unauthorized access to a portion of Uber Freight's systems and repositories. The incident was identified, contained, and remediated, and we promptly engaged federal law enforcement. "There has been no impact to Uber Freight's business operations, which continue in the normal course without disruption. Our systems are secure and fully operational." Uber Freight is the ubiquitous ride-sharing company's lesser-known logistics arm, which describes itself as "one of North America's largest managed transportation and multimodal capacity networks." Its website claims that it manages 18 million shipments carrying more than $17 billion worth of goods each year. The Register did not download the files Helix released in stages, and Uber Freight neither confirmed nor denied that the material was authentic. Helix is one of several recently established extortion brands linked by researchers to infrastructure associated with BlackFile, which retired its name in May. According to Google Threat Intelligence Group (GTIG), Helix shares infrastructure with the Pink, Redact, and Falcon brands. Google tracks the wider cluster of activity as UNC6671. Operators associated with UNC6671 often use vishing to gain an initial foothold, posing as IT helpdesk staff overseeing mandatory security migrations, Google said. They contact employees on their personal phones and use device code phishing to obtain credentials and authenticated sessions before siphoning data from cloud services such as Microsoft 365. They have also targeted Okta identity infrastructure. Researchers believe the UNC6671-linked brands have recently shifted toward organizations in higher-value sectors. Since June, they have favored technology, transportation, and hospitality targets after focusing on manufacturing, real estate, healthcare, and insurance during April and May. Why multiple brands emerged after BlackFile shut down is unclear. GTIG said the strategy could "compartmentalize operations, hide overall breach volumes, and isolate any negotiation fallout," although other plausible explanations exist. Internal disagreements over matters such as handling finances and operational security could have led to the fragmentation of UNC6671, GTIG speculated. The core members may also be looking to retain control over the intrusion and data theft aspects of the attack, while outsourcing negotiations and extortion. The different groups may also just be using the same commoditized phishing tools. ®
