Levi Strauss disclosed a recent cybersecurity incident in which an unauthorized third party accessed its systems through a social engineering attack targeting three employees. The company said in a regulatory filing that it has taken containment measures and opened an investigation, with preliminary findings showing certain corporate information was accessed and extracted. Levi said the incident has not disrupted operations and is not expected to have a material effect on operations or financial results. The disclosure comes as major companies face a broader rise in cyberattacks and ransomware incidents, with Google and internet intelligence data reviewed by Reuters indicating that phone-based, ransom-seeking hackers targeted dozens of prominent U.S. financial institutions and other businesses over the past month and set digital traps for more than 200 companies in the past five weeks, including Levi Strauss.
