Levi Strauss & Co. (Levi’s) has announced a cybersecurity incident involving an unauthorized third party who used social engineering to access the company's systems and exfiltrate corporate information from the systems of three employees. The clothing giant disclosed the incident in its filing with the U.S Securities and Exchange Commission (SEC). According to the SEC's investigation, certain corporate information was accessed and exfiltrated during the attack.
Several employees were targeted by the attackers through social engineering, which gave them access to their systems without their consent. Levi Strauss has not disclosed the precise social engineering technique used by the threat actor, or whether the threat actor made any extortion demands, but this incident specifically affected three company-provided computers. Levi Strauss stated that its security teams responded quickly to contain and terminate the unauthorized access.
According to Levi Strauss' preliminary investigation, it is not believed that customer information has been stolen. In addition, the company stated that the incident did not disrupt operations for the company.
Levi Strauss stated in its SEC filing that, based on preliminary findings from the Company's investigation, it believes that some corporate information has been accessed and exfiltrated as a result of the incident. Levi Strauss expects the incident to have no material impact on the company's financial position or business based on its preliminary findings so far. Levi Strauss will provide additional notifications as additional information becomes available.
The Levi Strauss & Co. (Levi’s) apparel company, one of the world's most recognizable companies, employs approximately 19,000 people and operates over 3,300 stores. The products are also available through third parties and online platforms. Levi Strauss has not identified the threat actor responsible for the intrusion or revealed whether the company received any extortion demands from the attacker. Unconfirmed reports suggest that the hacker may have been associated with UNC6671, a hacking group that has been associated with recent voice phishing attacks.
According to Levi Strauss, the attribution has not been confirmed, and it remains unclear what tactics were employed in the attack.
There is a general indication that the Levi Strauss incident occurred at the same time as a broader wave of voice phishing and social engineering attacks targeting major organizations.
According to Google and other internet intelligence sources consulted by Reuters, ransom-seeking attackers were attempting to compromise victims through phone calls in recent weeks by targeting dozens of prominent financial institutions and other organizations in the United States.
Levi Strauss was among more than 200 companies targeted with digital traps over the course of five weeks with the same intelligence. Levi Strauss has not confirmed the possible connection, and the attackers, the specific corporate information stolen, and the method of targeting employees are still under investigation.
Despite the company's assertion that customer information was not compromised, the incident demonstrates the continuing threat posed by social engineering and phishing attacks. Organizations continue to be vulnerable when attackers can manipulate employees into providing access to corporate systems and information.
In response to the attackers' attempt to gain access to the compromised computers, the company immediately responded and contained them. Levi Strauss has not reported any interruption to its business operations and does not believe the incident has, or is reasonably likely to have, a material impact on its financial or business position at this time.
Despite the breach, Levi Strauss has not reported any operational impacts and continues to investigate the incident.
Levi Strauss' incident illustrates the growing threat of voice-phishing and social engineering attacks against large corporations. Although the company has indicated that the customer data was not compromised, the ongoing investigation emphasizes the need for employee awareness, access controls, and rapid response to targeted cyberattacks to limit their impact.
