Levi Strauss & Co disclosed a cyberattack in an SEC filing, revealing that social engineering was used to compromise three employees' company-issued computers, resulting in corporate data being accessed and exfiltrated. The company says it has contained the incident and evicted the attackers, with no customer data or business operations appearing to have been affected. The investigation is ongoing, and unconfirmed reports suggest the hacking group UNC6671, known for voice phishing campaigns, may have been responsible.
