From the desk of Thomas F. Duffy, MS-ISAC Chair

The number of scams and malware taking advantage of social media users and platforms is on the rise. Social media scams are easy to create and can target thousands of people at once due to how users interact with pages, posts, and contacts. Once your account is compromised, malicious actors can leverage it as a conduit to spread scams and malware to your network of friends or contacts. Facebook, Twitter, LinkedIn, and Instagram are a few very common examples of social media sites where you or your account could be at risk.

If the answer to any of the following questions is “NO,” that means your computer is infected with Fireball or a similar adware.
Open your web browser and check:

  1. Did you set your homepage?
  2. Are you able to modify your browser’s homepage?
  3. Are you familiar with your default search engine and can modify that as well?
  4. Do you remember installing all of your browser extensions?

To remove the adware, just uninstall the respective application from your computer (or use an adware cleaner software) and then restore/reset your browser configurations to default settings.

The primary way to prevent such infections is to be very careful when you agree to install.

You should always pay attention when installing software, as software installers usually include optional installs. Opt for custom installation and then de-select anything that is unnecessary or unfamiliar.

Now that W-2’s are arriving, it’s time to consider how to stay safe from tax season scams. Every year, unfortunate taxpayers go to file their returns and are shocked to find that someone else has filed a fraudulent one in their name! Some innocent people also receive fraudulent phone calls from criminals impersonating tax officials. Sadly, tax fraud has only become more widespread and digital communication has opened new ways for it to happen.

While the Internal Revenue Service (IRS) reports on multiple tax-payer related scams, and even publishes a “Dirty Dozen” list , three scams variants are worth highlighting: Phishing and Malware Schemes; Identity Theft and Falsely Filed Tax Returns; and Impersonation Scams. Once criminals have your information, they can also continue to commit identity theft well beyond tax season. Here are some details on each of these scams, along with how to identify them and seek help in case of identity theft.

More information for staying safe during this tax season is available on the Center for Internet Security site.

OVERVIEW:
Multiple vulnerabilities have been discovered in iOS, watchOS, tvOS, iTunes, OS X El Capitan, and Safari which could allow for arbitrary code execution. Apple iOS is an operating system for iPhone, iPod touch, and iPad. watchOS is the mobile operating system of the Apple Watch. tvOS is an operating system for Apple TV digital media player. Apple iTunes is used to play media files on Microsoft Windows and MAC OS X platforms. OS X El Capitan is an operating system for Macintosh computers. Apple Safari is a web browser available for OS X and Microsoft Windows.

Successful exploitation of these vulnerabilities could result in, but are not limited to information disclosure, giving an attacker the ability determine kernel memory layout, or allow for arbitrary code to be run within the context of the user or kernel.

RECOMMENDATIONS:
We recommend the following actions be taken:

  • Apply appropriate updates provided by Apple to vulnerable systems immediately after appropriate testing.
  • Run all software as a non-privileged user to diminish the effects of a successful attack.
  • Do not to download, accept, or execute files from un-trusted or unknown sources.
  • Do not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
