Security News and Updates

Ransomeware Alert

As you may be aware, many organizations across the world have been impacted by the ransomware known as Petrwrap, Petya or similar names. The exploit is similar to the Wannacry outbreak from May 2017. At this time, none of the infections reported have been introduced within our internal US systems. Altice USA employs best practices for endpoint protection, vulnerability management, and perimeter defense; the following practices have been effective in preventing this malware on Altice USA's (Cablevision and Suddenlink) networks:

  • Endpoint protection (e.g., antiviral software) assures software for detecting malware is deployed and up dated, including updates to specifically detect the reported ransomware.
  • Vulnerability management ensures networks and systems are inspected for vulnerabilities and remediated through patching at regular intervals. Our systems have been updated with the Microsoft-recommended critical patch for protection against the reported ransomware.
  • Perimeter defense restricts network traffic including a specific policy to block Windows Systems traffic from external sources therefore preventing the spread of the malicious ransomware.

Our security operations continue to monitor for indications of the malware and are staying connected with our security partners and federal agencies for situation updates. While we certainly have taken additional action to protect both our network and that of our customers, it remains incumbent on our customers to take similar action to protect their own networks.

Security Alert: Uninstall QuickTime for Windows

According to the U.S. Department of Homeland Security, it was recently discovered that, if a customer has QuickTime for Microsoft Windows installed on their PC, it could allow online attackers to easily infect their computer when browsing compromised or malicious websites. QuickTime for Windows is an Apple product, and Apple is no longer providing support or security fixes for it. Therefore, security software companies and the U.S. Department of Homeland Security recommend that customers uninstall QuickTime for Windows to protect themselves from potential online threats. Customers with QuickTime for Mac are not affected by this issue.

Many web browsers, including Internet Explorer, Mozilla Firefox, and Google Chrome, provide media player functionality similar to that of QuickTime and can serve as alternatives going forward.

Be aware of seasonal IRS scams

As we head into a new calendar year and approach the common April 15th filing deadline for income taxes, Optimum customers should be aware that scammers have continued to evolve tax season-related schemes. The U.S. Government's Internal Revenue Service (IRS) does not solicit payments from people via email or websites. The IRS does not accept payments on pre-paid debit cards (such as GreenDot or similar).

If you have received a phone call or email claiming to be from the U.S. Government or the IRS that requests you to make a payment using a pre-paid debit card, please be aware that this request is fraudulent. Do not follow the links provided in these e-mails. Callers that ask you to visit websites or type commands into your computer could be attempting to infect your computer with malware that could allow the scammers to access your computer, render your files (documents, photos, etc.) inaccessible, detect the passwords you type, and commit other fraudulent activities.

As your security is very important to us, we encourage you to:

  • Be wary of unsolicited calls and emails asking you for payments, especially using pre-paid debit cards.
  • Be wary of telephone calls and emails requesting payment or personal information by individuals claiming to be from government agencies.
  • Use a quality security suite that includes anti-malware, browser protection, and a password manager. Optimum offers internet protection powered by McAfee, at no cost to Optimum Online customers, that provides these features on up to 20 devices. Visit http://www.optimum.net/protect for more information and to download the software.

Your Computer Is Infected Phone Scam

At Optimum, the security of your computer and personal information is our priority, so we're advising our customers to be aware of a phone scam that is targeting computer users. The scam usually begins with a phone call from someone claiming to be a tech support expert from Microsoft, Optimum or some other well-known technology company. The "expert" claims that your computer is infected with a virus or is sending error messages. In order to fix the "problem," the scammer asks for remote access to your computer to check for threats. Once the scammer is given access, they not only have access to all your information, they also seek a fee for the "service" provided.

Optimum never makes unsolicited phone calls to our customers. If you get a call from someone who claims to be tech support, hang up and call Optimum directly using the Customer Support number listed here. Please keep in mind that web search or directory service for the Optimum Customer Support phone number might yield fraudulent results, which could lead you contacting a scammer unwittingly. For your safety, please make this page your first stop to find all the correct, secure and verified contact information to reach us 24 hours a day.

Thanks for being an Optimum customer.


Fake FBI/Department of Justice Message

Optimum customers are advised to be aware of a recent virus, that once loaded on a computer, displays a page claiming a copyright violation has occurred. This page "freezes" the infected machine, and demands payment of a fine to restore normal access.

If you are experiencing this issue on your computer, do not follow payment instructions.

Protecting your email

Tips To Protect Your Information

Here are a few tips to help identify suspicious e-mails and protect your information:

  • Generally, if you receive a suspicious e-mail from a financial institution or online retailer, do nothing. Do not reply to the e-mail, or click on any of the links. Do not give any personal details to the sender.
  • Do not provide personal information via e-mail, unless you are certain of a person's authority to have the information.
  • If you get an e-mail that warns you, with little or no notice, that your account will be shut down unless you reconfirm your billing information, do not reply or click on any link in the e-mail. Instead, contact the company cited in the e-mail using a telephone number or web site address known to be genuine.
  • Avoid e-mailing personal and financial information. Before submitting financial information through a web site, look for the "lock" icon on the browser's status bar. It signals that your information is secure during transmission.
  • Review credit card and bank account statements as soon as you receive them to determine whether there are any unauthorized charges. If your statement is late by more than a couple of days, call your credit card company or bank to confirm your billing address and account balances.
  • Be suspicious of unsolicited phone calls, visits, or e-mail messages from individuals asking about employees or other internal information. If an unknown individual claims to be from a legitimate organization, attempt to verify his or her identity directly with the company.
  • Pay attention to the URL of a web site. Malicious web sites may look identical to a legitimate site, but the URL may use a variation in spelling or a different domain (e.g., .com vs. .net). Be aware that the true URL of a link is often masked in the e-mail text, so never click on hyperlinks within e-mails. Instead, copy and paste them into the browser.
  • If you're unsure whether an e-mail request is legitimate, attempt to verify it by contacting the company directly. Do not use contact information provided on a web site connected to the request; instead, check previous statements for contact information.

Notice About Phishing Scams

It has come to our attention that some of our customers may have recently received an e-mail falsely representing that it was from Optimum Online, requesting customers to reply with their Optimum Online password. E-mails such as this, referred to as "phishing" e-mails, typically attempt to fraudulently acquire sensitive information, such as usernames, passwords, credit card details or other personal information, by claiming such information is required for account verification, to prevent account termination or some other course of action in connection with your account.

As a policy, Optimum Online will never contact customers via e-mail requesting personal information or passwords.

If you have already responded to an e-mail of this nature and released your Optimum Online password or other personal information, you should consider the information compromised. You may change your e-mail password online using the Reset password page. You may also call your local Customer Support Center.
