VF Corp, the owner of brands like Vans and The North Face, saw its shares tumble over 7% after announcing it suffered a cyberattack. The company said the cyberattack encrypted some of its systems and hackers stole personal data, indicating it was likely a ransomware attack although the company did not confirm. The attack is expected to have a material effect on VF Corp's business according to its SEC filing, as it gears up for the busy holiday season. Fulfilling orders may be hampered.
