Cyber Threats

Cyber threats are Internet-borne activities that may harm a computer or network and impact the availability of network data or systems. Cyber threats may target institutions’ computer systems, internet service providers, or personal devices, such as computers, tablets, and smart phones. Examples of cyber threats include keystroke logging, malware, phishing, and denial of service.

Cyber threats may originate from a variety of sources with specific or unspecified targets. Any website or internet property can be a potential target.

Denial of service (DoS)

DoS is a deliberate attempt to disrupt business operations by flooding an online or mobile website with a high volume of traffic. DoS makes it difficult for customers to access their accounts online by creating an electronic traffic jam that restricts or prevents access to a website. Even though past denial-of-service events targeting Wells Fargo were designed to hamper accessibility, customer account and personal information remained safe.

Wells Fargo has significant protections in place in an effort to ensure our online and mobile channels remain secure and available so we can service our customers’ financial needs.

If you're having difficulty accessing the site or mobile banking, try logging on again as the disruption is usually intermittent. You can also access your accounts through our ATMs, stores, or by phone at 1-800-869-3557.
