Attackers commonly use the macro functionality found in Microsoft Word and Excel to attack their victims. They attach malicious document file to an email. When opened, the files can lead to a virus infection on your computer. If you ever get a message with any of these attachments, particularly if you were not expecting it, do NOT open the attachment.
We have received reports for faked order confirmation and fake invoice emails this week that have been well crafted. The faked emails included malicious Microsoft Word documents bearing malware. A couple of examples are included below.
ALWAYS verify unexpected emails with the sender, particularly if they include attachments.
NEVER open attachments that you are not expecting without first verifying they are legitimate with the sender.
If you do open an attachment or file that you suspect is malicious unplug your network cable and contact the helpdesk at x2200 immediately.
Several members of our community have recently reported being prompted to install MacKeeper on their Apple computers running Mac OS X. MacKeeper is malicious software of the adware variety. While MacKeeper offers legitimate services for a fee, it also opens security holes in your system that can introduce other forms of malware and adware which cause problems for your web browser and OS X operating system, such as performance or integrity issues. Do Not install MacKeeper!
MacKeeper is offered by the company Kromtech (formerly ZeoBIT) and has been identified in issues such as fraudulent installs masquerading as other anti-virus applications such as ClamXav. MacKeeper is also known for predacious distribution practices employing other adware to market and distribute their product through pop-up ads. It has also been used to distribute other malware exploits such as OS X/Agent-ANTU as reported by researchers at BAE and Sophos.
If you suspect that you may have installed MacKeeper please contact the Help Desk at x2200 for help removing this software.
Mobile devices have become one of the primary ways that we communicate and interact with each other. Powerful computers now fit in our pockets and on our wrists, allowing us to bank, shop, view our medical history, work remotely, and communicate from virtually anywhere. With all this convenience comes added risk, so here are some tips to help secure your devices and protect your personal information.
Password-protect your devices. Protect the data on your mobile device and enable encryption by enabling passwords, PINs, fingerprint scans, or other forms of authentication. On most current mobile operating systems you have the option to encrypt your data when you have a password turned on. Turn it on!
Secure those devices and backup data. Make sure that you can remotely lock and/or wipe each mobile device. That also means you should back up your data on each device in case you need to use the remote wipe function. Services such as iCloud, OneDrive, and Google offer device location, wipe and backup services.
Verify app permissions. Don’t forget to review which privacy-related permissions each application is requesting, before installing it. Be cautious of fake applications masquerading as legitimate programs by verifying that the application is from a reputable source, such as the Apple Apps Store, Microsoft’s Store, or Google’s Play Store. Occasionally, applications in the official stores can include malware. Read reviews and descriptions carefully. Only install applications that you need. Remove applications that you are no longer using.
Update operating systems. Security fixes or patches for mobile devices’ operating systems are often included in these updates. Just like patching a computer, iOS, Android, and Windows Mobile all need to be patched and kept current.
Be cautious of public Wi-Fi hotspots. When using your mobile device, watch for connections to public hotspots. Many mobile devices will automatically connect to hotspots and prioritize data transmission over Wi-Fi by default. Verify that your settings require manually selecting hotspots if possible. Working with sensitive data while connected to a public hotspot could lead to unintended data exposure. Always ensure that you are using a secure connection.
