URGENT Malware/Ransomware Newsletter – May 2017
As you may have heard, a new threat has emerged on the internet known as WannaCry (AKA Wcry and WannaCryptor), although the exploit is not new as far as what it does, this latest ransomware threat has already crippled companies overseas and has started to show up in the U.S. including FedEx. The threat comes in the form of a malicious email, that may have a fake invoice (PDF or Word Document) or something similar attached that sounds important (to make you want to open it). The exploit can launch once the attachment is opened. Some have also reported that simply previewing the email can launch the hidden script in the background to launch the ransomware process (but this is unverified).

This is a serious threat because once your system is infected, you will have to pay for the decryption key or all of your photos, docs and other files will be in an unusable state. The attackers are demanding payment in Bitcoin and you don’t have very long to get them the ransom before they threaten to delete your decryption key, leaving your data forever locked. There are several ways to protect yourself (and/or your company) shown below:
1) STEP 1 : Ensure you are running your Windows Updates. This particular exploit uses a vulnerability in Microsoft Windows (all versions, including Server O/S). Those who use DNS Texas for computer management (those with their own servers in most cases) – we are deploying the hotfixes to your servers and workstations today (5/13/2017). Those on home computers should manually run Windows Update to ensure all security patches are applied. For the tech savvy, patches specifically that need to be installed (if you don’t like letting everything install) can be found here: https://technet.microsoft.com/en-us/library/security/ms17-010.aspx

2) STEP 2 : Make sure your virus or malware protection is up-to-date! Microsoft includes Windows Defender in Windows 8.1 and higher which is a decent start, although it doesn’t catch everything, Microsoft does confirm that, if up-to-date, it will help mitigate this current threat. To add additional safety, complimenting your current antivirus solution, you can add additional protection by installing MalwareBytes. The premium (paid) version of this software can actually replace your antivirus and goes above and beyond by looking real-time at the websites you are visiting, blocking known bad sites from even displaying, protecting from ransomware, malware and rootkits, all on the fly. NOTE: On Windows VISTA and Windows 7 Microsoft Antivirus is no longer supported/updated – your system could be unprotected! MalwareBytes is a logical solution for Windows Vista and Windows 7 computers. It can also protect Windows XP. All MalwareBytes premium customers are protected from WCRY, per the company website.
