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, software bugs, 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.

Heartbleed bug

The internet bug known as “Heartbleed” is a vulnerability with the open-source encryption software, OpenSSL, which protects an estimated two-thirds of all internet websites. This bug is believed to have existed since 2012 and was disclosed publicly on April 7, 2014. Heartbleed has had no impact on the safety of online and mobile banking at Wells Fargo.

Wells Fargo constantly monitors for vulnerabilities and we make updates as needed to keep online and mobile banking safe for our customers. You can help protect your personal and account information by ensuring:

  • Your online banking username and password are different than those used for other online accounts or activities.
  • You change your username and password periodically through online banking, using a combination of letters, numbers, and special characters.
  • You regularly review your statements and account activity through online banking for suspicious transactions.

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.
