Dec 2, 2019

Original release date: December 2, 2019Cyber Monday draw millions of shoppers online for deals and savings, but this day also provides opportunities for an attacker to steal personal information. The Cybersecurity and Infrastructure Security Agency (CISA) reminds users to remain vigilant when browsing or shopping online.

Before providing any information, make sure that you are interacting with a reputable, established vendor. Some attackers may try to trick you by creating malicious websites that appear to be legitimate, so you should verify the legitimacy before supplying any information. (See Avoiding Social Engineering and Phishing Attacks.) Use caution with email links and attachments. Take appropriate precautions when using email and web browsers to reduce the risk of an infection. Be wary of unsolicited email attachments and avoid clicking on email links, even if they seem to come from people or businesses you know. (See Using Caution with Email Attachments.) Pay using a credit card. There are laws to limit your liability for fraudulent credit card charges, but debit cards may not have the same level of protection. Ensure your information is encrypted. Check website URLs to ensure they begin with "https:" (instead of "http:") accompanied by a padlock icon to verify that the site is secure.

Nov 27, 2019

Original release date: November 27, 2019Black Friday is one of the most lucrative shopping days of the year for retailers in brick-and-mortar shops and online, but shoppers aren't the only ones looking for deals. Malicious people may be able to obtain personal information (such as credit card numbers, phone numbers, account numbers, and addresses) by stealing your wallet, overhearing a phone conversation, rummaging through your trash (a practice known as dumpster diving), or picking up a receipt at a restaurant that has your account number on it. If a thief has enough information, he or she may be able to impersonate you to purchase items, open new accounts, or apply for loans. The Cybersecurity and Infrastructure Security Agency (CISA) encourages holiday shoppers to take the following identity theft precautions: Take advantage of security features. Passwords and other security features add layers of protection if used appropriately. (See Choosing and Protecting Passwords.) Check privacy policies. Take precautions when providing information, and make sure to check published privacy policies to see how a company will use or distribute your information. (See Protecting Your Privacy.) Check your statements. Keep a record of your purchases and copies of confirmation pages, and compare them to your bank statements. If there is a discrepancy, report it immediately. Be careful what information you publicize. Attackers may be able to piece together information from a variety of sources. Avoid posting personal data in public forums.

Securing Portable Electronic Devices During Travel

Nov 22, 2019

Original release date: November 22, 2019Holiday travelers often use portable electronic devices (PEDs) because they offer a range of conveniences, for example, enabling the traveler to order gifts on-the-go, access to online banking, or download boarding passes. However, these devices are vulnerable to cyberattack or theft, resulting in exposure of personal information. With the holiday season approaching, the Cybersecurity and Infrastructure Security Agency (CISA) reminds users to be mindful of the security risks associated with traveling with PEDs. CISA encourages travelers to take the following steps to protect their personal information: Avoid using public Wi-Fi networks to conduct personal business. Open Wi-Fi networks at places such as airports present an opportunity for attackers to intercept sensitive information. Turn off Bluetooth when not in use. Cyber criminals have the capability to pair with your device's open Bluetooth connection and steal personal information. Be cautious when charging. Avoid connecting your device to any computer or charging station that you do not control, such as a charging station at an airport terminal. Remember physical security. Do not leave your device unattended in public or easily accessible areas. Check out CISA’s Tips on Holiday Traveling with Personal Internet-Enabled Devices and Cybersecurity for Electronic Devices for more information and tips.   This product is provided subject to this Notification and this Privacy & Use policy.
