Dealing with Newsletter and Subscription bombs
ExchangeDefender now protects you from malicious subscriptions to newsletters and emails you never opted into through “Subscription (Newsletter) Bomb Protection” available at admin.exchangedefender.com. By enabling the feature all newsletter “CAN-SPAM” “legitimate sender” content that you don’t want in your mailbox will automatically be filtered out as SureSPAM by ExchangeDefender.

The Bomb Issue
Hackers are currently exploiting security issues in newsletter software that allows them to add your email address to a mailing list without validation. If you’ve signed up for anything recently you know that you’re generally sent a confirmation email to validate you own the email address — well, hackers have found a way to add your email to the list without that step. Repeated thousands of times, it gives hackers a way to blow up your mailbox through a broadcast storm by otherwise legitimate senders who cannot tell your email address from thousands of others on their mailing list.

The ExchangeDefender Solution
ExchangeDefender already has a built-in newsletter management software (where you can have all of your newsletters skip your inbox and be available for reading online). We can effectively quarantine all the newsletters for you and allow you to read them online without them hitting your inbox and putting you over the quota. With the Subscription Bomb protection we go an extra step and outright classify these newsletters you haven’t subscribed to as SureSPAM. You can still access them but they won’t bother you or damage your Inbox or productivity.

There are 3 options:
Enabled: Protection is turned on and any newsletter will be flagged as SureSPAM. We do not recommend this option as it will catch all newsletters, whether you’ve subscribed to them or not.
Disabled: No protection. This is the default setting at the moment for all domains.
Whitelisted: Protection from newsletters but whitelisted ones will still get through. This allows you to have the best of both worlds: protection from newsletters you didn’t subscribe to but newsletters you want and have whitelisted will still come through. On January 1, 2019 this will be the default setting.

What do I tell my clients?
ExchangeDefender can now protect you from SPAM being generated by legitimate newsletter and subscription providers – if someone steals your identity (your email address, name, etc) they can subscribe you to newsletters without your knowledge or permission. Because the sending and management of these lists is automated, hackers can get an innocent third party to send you thousands of newsletters to clog up your inbox, make you wait for your email to download, and just make your email experience miserable.

ExchangeDefender can detect newsletters and “legitimate marketing emails” with unsubscribe or newsletter control keywords and automatically filter it out from you. Messages aren’t gone, you can still access them through admin.exchangedefender.com in realtime and on demand, but your Inbox will stay clean.

ExchangeDefender Office Macro (OLE) Dangerous Content Filtering

ExchangeDefender now includes advanced protection from dangerous Microsoft Office macro code (OLE). Since usage of Office macro code is very limited (and seldom moved via email) it’s almost universally used as an attack vector by hackers who send malicious macro code embedded in Microsoft Office documents that target vulnerabilities in Outlook, Word, Excel, Powerpoint, and more.

Specifically, our service scans the following attachments for the presence of dangerous, encrypted, malformed, malicious, or suspicious code: doc,dot,pot,ppa,pps,ppt,sldm,xl,xla,xls,xlt,xslb,docm,dotm,ppam,potm,ppst,ppsm,pptm,sldm,xlm,xlam,xlsb,xlsm, and xltm. If we detect something suspicious or dangerous the message will not be destroyed or quarantined (as is the case with virus or infected attachments) – rather we just filter it to SureSPAM.

Managing Your OLE Protection

We will start strictly enforcing macro protection on January 1, 2019. However, the feature is available now and can be enabled at any time by going to https://admin.exchangedefender.com and logging in as a domain administrator (if you don’t see the setting, you aren’t logging in with your domain account but your personal or service provider account).

Click on Configuration > Policies > Phishing Options.

At the bottom of the form you will see “ExchangeDefender Office Macro Protection” section that is currently (October 2018) set to Off. The following options are available:

Off – Turns off ExchangeDefender Office Macro (OLE) protection
On – Turns on the protection but whitelisting the domain/email will bypass it
Strict – Turns on the protection and ignores whitelists

ExchangeDefender recommends this setting be configured as Strict in order to protect from spoofing where clients own domain or vendor (that doesn’t have SPF/DKIM implemented) address is used to deliver a dangerous attachment. Using “Strict” setting bypasses whitelist checks so if the message contains dangerous content it will automatically go into SureSPAM even if the domain is whitelisted.

What do I tell the users?

First, set the setting to Strict. Then, adjust the date in the message below and make sure SureSPAM settings are set to Quarantine.

“Starting with January 1, 2019, ExchangeDefender will protect you from dangerous attachments that contain rarely used Microsoft Office macro (OLE) code. If dangerous macro code is detected in an attachment, message will go into SureSPAM category and if configured to quarantine the message will be accessible at https://admin.exchangedefender.com in the SureSPAM quarantine. We have enabled the protection for you. If you ever see a familiar contact/domain but you were not expecting the message, it’s likely being spoofed/forged in order to trick you to click on a dangerous attachment. Take an extra step and contact the sender asking them if they sent you a document. If not, delete the message.”

We hope this helps keep your users more secure and in our production use so far it’s helping stop 100% of dangerous content

 

ExchangeDefender Encryption Enrollment Account Reset

Encryption is hot – with daily news of hackers breaking in or compromising one system after another, taking that extra step to make sure your information is safe and secure has never been on the minds of business owners more. We may sound like a broken record when it comes to encryption but it is one of our more popular products and today we’re happy to announce another quick feature that is coming.

October 1st: You can now reset your recipients accounts (PIN+Password) in Corporate Encryption.

ExchangeDefender Corporate Encryption has an alternate [ENCRYPT] flag that can allow the users to encrypt messages on demand and require the recipient to enroll in the ExchangeDefender Corporate Encryption in order to access the message. Enrollment process is quick and simple and requires the recipient to provide their name and phone number along with a selection of a password and a 4 digit PIN. This additional security step is put in place to eliminate man in the middle attacks where a hacker may have compromised the firewall, disgruntled employee is trying to spy on inbound mail, or a variety of other threatening issues. It is the ultimate layer of protection because PIN is only known to the user.

If you support ExchangeDefender Corporate Encryption, you’re going to like this feature a lot because you’ve likely had to deal with the inevitable case of a recipient forgetting both their password and their PIN. Since we have no way to verify the users identity, we’ve always processed reset requests manually. Now, this process is automated.

Just go to admin.exchangedefender.com and login as the domain administrator.  If you subscribe to Corporate Encryption you will see it under the Configuration menu. Simply type in the recipients email address and their account at ExchangeDefender will be reset allowing them to enroll again.

As a security precaution, they will not be able to see emails sent to them prior to the enrollment period – only new messages after they have created their account. On the backend, there are additional checks in order to make sure that this is actually a user that receives email from your domain, etc, etc so we don’t open the door to a malicious ExchangeDefender client attempting to reset accounts of unknown contacts. Obviously there is far more going on in the background that we cannot disclose in a blog post but if you’re interested in the technology, we have patents pending on several of these and would be happy to discuss privately.

There you have it, October 1st. Another cool feature that will save a lot of time for our users while keeping everyone just a little bit safer. We’re adding more features all over the place so please stay tuned to our blog and our Facebook page.

 

Email encryption is on the rise, ExchangeDefender offers two types of encryption.

Corporate Encryption

ExchangeDefender Encryption (Corporate Encryption) has been one of our hottest products for years, the demand for it is fueled by daily news of exploits, hacking, data theft and so on. Just last night, one of the largest retailers in the world was exploited and for over a month hackers stole credit cards and client information. This sort of daily reporting is creating an unprecedented demand for encryption products, with Let’s Encrypt becoming the largest SSL certificate issuer on the planet.

One thing remains, if the data you are sending or receiving is sensitive to you it’s your responsibility and best interest to assure it is protected.

When it comes to email encryption things get a bit more confusing, complicated, fragmented and unclear. One thing remains, if the data you are sending or receiving is sensitive to you it’s your responsibility and best interest to assure it is protected. Whether you’re the sender or the recipient. Unfortunately, email alone isn’t secure enough by design and <big deal>it is the most exploited and hacked medium available.</bigdeal> . Why hack a bank when I can hack your mailbox and get all your accounts, credentials, reset mechanisms, notes, private information and more?

This is where ExchangeDefender, and ExchangeDefender Encryption, become such a big deal and such a valuable <i>service</i> for your business. You can exchange emails back and forth securely, without installing any software, without requiring the recipient to install any software. Your still use your same email program, desktop, mobile phone, tablet – but your information goes from point to point in an encrypted and protected process. Not just that but you get things you typically can’t get from IT – knowing when the message was was received, when it was read, how many times it’s been read, and you get a reply in the same secure way.

ExchangeDefender Corporate Encryption
ExchangeDefender Corporate Encryption

ExchangeDefender Corporate Encryption now allows you to send encrypted attachments and share files securely from any device, even many of you that aren’t on Microsoft Outlook/Exchange. It was one of the more popular parts of the webinar we held yesterday (hope you had a chance to attend it, you can watch it anytime in our secure portal at https://support.ownwebnow.com)

ExchangeDefender Corporate Encryption was designed to eliminate the pain point of traditional key-based email encryption: too much software, too much management, exchange of public keys, software deployment, and more. It also eliminates the complaints about cloud based solutions that are often clunky, unfriendly, not to mention expensive. ExchangeDefender Corporate Encryption is none of those: it is friendly, affordable, requires no additional software or hardware.

And as of this week, it allows the sender and the recipient to exchange attachments so that the content is encrypted in both directions. Furthermore, because it is cloud based, you can resume work when you get back to your desk. The upgrades to the UI allow you to quickly see new messages, respond to them, or forward them elsewhere. It is truly turning into a highly secure, policy-based, email solution for businesses that require compliance and content security.

We’ve also made the UI more friendly by putting actions on top of the page so that it resembles popular webmail products end users have gotten used to for over a decade. Attachments are a lot more prominent and go both ways: not only can you send them, but when the recipient logs into our portal to reply they can attach anything they want to in response as well – assuring that content is protected and encrypted at all times.

 

ExchangeDefender mail flow and email analysis troubleshooting is at times a long and difficult process that has been automated through our admin portal at  https://admin.exchangedefender.com. We realize that it’s not an option for some of our end users and new MSPs so we often get tickets in our support portal asking us why a certain message got delayed, rejected, classified as SPAM or allowed to get through if it had SPAM content, etc.

In order to troubleshoot an issue with a specific message we always ask for SMTP headers. The following blog post will help you find them in Outlook Web App, Outlook 2013 and Outlook 2016.

Outlook Web App

From the message listing, right click on the message and select “View Message Details”:

 

 

 

 

 

 

 

 

You will see Message details screen. Copy and paste it in the ticket and we can help you with the rest.

 

 

 

 

 

 

 

 

 

Outlook 2013 / Outlook 2016

From the message listing double click on the message so it pops up in it’s own Outlook window.

 

 

 

 

 

 

 

 

 

 

 

Then click on File and you will be shown the message file options:

 

 

 

 

 

 

 

 

Click on Properties and you will see the SMTP headers. Copy and paste it in the ticket and we can help you with the rest.

 

 

 

 

 

 

 

 

Important: Please copy and paste the contents of the screen into our support ticket instead of taking a screenshot. Sometimes the SMTP headers contain characters that are very similar (qf9mfIlI1IlI) and it can take a lot longer to locate the message rather than having a specific text search.

What happens next is that our team is able to locate the specific message in our database and then with that data do further analysis using the node that processed the message and look at all the logs generated by hundreds of different services that are analyzing every message for dangerous content.

 

 

About the PIN requests

Several years ago we introduced the ExchangeDefender Phone PIN support to enable our clients and partners to obtain full support over the phone as if they were in our support portal. Being able to talk to someone that can directly make any change you need to make on the go is incredibly valuable for on-the-go business manager that is typical in SMB.

Our implementation left a lot to be desired. We put the PIN in the area where few people looked. We had no system to quickly retrieve your PIN. Some of our support techs took advantage of the system to avoid helping clients. All these issues have been addressed so we wanted to go over our phone support process again.

Our Support Process

We have a typical 3 tier support system – people on the phones (Level 1), people in the support portal (Level 2), and people managing network services and software that approve overrides and make changes manually (Level 3).
When you call 877-546-0316, you will always be speaking to a Level 1 person. Their job is to be friendly and help you figure out how to get things done. In general, they will walk you through the portal, provide our manuals and walk through guides, open a ticket on your behalf, and sometimes even provide additional information about services. Their goal is to eliminate the clutter, the transfers, the “not my department, not my job” you often get when you call a company for help.

If you call our support and are active, in good standing (no late or past due invoices), with proper credentials – our team will greet you with “Thank you for calling ExchangeDefender, whom do I have the pleasure of speaking” and will try to locate your profile and your PIN. From there, we’ll take good care of you. If you don’t know your pin, or if we cannot locate you in the portal, our support will still provide basic public information about our services but is prohibited from discussing pricing, settings, passwords, company data and so on. This is for your security and protection – we’ve all experienced identity theft, people pretending to be someone else, people that have been terminated looking to sabotage their employer, etc – the PIN removes that from being an issue.

What requires a PIN?

Anything that is not public or available on our web site will require you to provide an email address and a PIN. Things that don’t require a PIN are basic answers about how our products work, where to find documentation, if there are any issues with services at the moment, how to become a partner, marketing collateral requests, etc.
Everything else that is account-confidential will require a PIN, for example:

– Getting a copy of the invoice, pricing information
– Account modification, service change, settings change
– Opening a new support ticket on your behalf
– Adding a new service or subscription
– Modifying service settings (passwords, IP addresses, credentials)

There are only two things that our support on the phone will not do regardless of whether you know your PIN or not: add a new contact to the support portal and delete any service/subscription. For legal, compliance, and past experience reasons that is a red line we cannot cross.
OK so how do I get my PIN?
You can find it in your Contact information at https://support.ownwebnow.com
If you don’t know your PIN or support password, you can request a new PIN at https://exchangedefender.com/pin
If you don’t have a contact in our portal at all, you will be provided with a PDF to provide to whoever manages the ExchangeDefender relationship in your organization.

We hope that as we introduce chat and more phone support you can still get everything you want done much faster and more efficiently – but most of all: securely.

Development and service improvement around ExchangeDefender is really in a different gear now and we have a huge webinar to discuss all the new stuff that you will start seeing in September:

–  New Shockey Monkey Service Manager UI (for private portals)
–  Exchange 2016 rollout for SMB clients
–  Upgrades to IoT for CAN-SPAM tracking/issues
–  Allowing threaded conversations in Web File Sharing
–  Allowing file exchange through Corporate Encryption
–  ExchangeDefender Pro UI changes
–  and much more.

It’s a LOT of stuff with HUGE improvements all around so if you work with us you’ll really want to attend:

ExchangeDefender New Stuff Webinar
Wednesday, September 5th. Noon EST
https://attendee.gotowebinar.com/register/1810967512151336450

Since February of 2017 we’ve been working on core infrastructure updates to address major weaknesses in the previous infrastructure model and have embraced rapid development, regulatory compliance requirements, different laws and regulations impacting our clients all over the world, and major needs our clients expressed that required development at a different scale. This again puts us (and you) ahead of the competition and we look forward to helping you gain more business.

Tune in!



Mobile Device Security

ExchangeDefender protects pretty much any device that has access to email – and a category most prone to email-borne security exploits are mobile devices. ExchangeDefender Pro and our Exchange hosting services can nearly eliminate an attack vector through malware detection, phishing attempt alerts and can help you wipe a device remotely without having physical access to it.

Malware

The number one way to get malicious content to a mobile device is still via email – it’s so easy to trick a user to click on a malicious link and on a mobile device it is far harder to tell if the sender is legitimate or spoofed. Hackers format messages in such a way that it’s easy to see legitimate links and accidentally click on malicious ones so ExchangeDefender is extremely useful in making sure any such dangerous content is stripped off in the cloud. Anyone can email any content they wish to your mobile device and with ExchangeDefender you are assured that even the most aggressive of 0 day exploits do not arrive in your users mailbox.

Phishing

Phishing, or forging/deceiving an identity of a third party, is a popular way for hackers to get users to click on links that appear to be legitimate. It’s very easy to copy a look of an Amazon or bank email notification and get the user to click on the link that takes them to a forged web site to download malicious content. Unlike Malware protection, which removes dangerous content from the email, phishing protection deactivates links in email messages and highlights phishing attempts when links to third party sites do not match the domain name of the sender. If you were getting an email from jeff@amazon.com would he be including a link to http://1001smallbizscamsandfrauds-519.org? Our system will deactivate that link and keep your user safe from whatever is on the malicious site.

Remote Wipe & Device loss management

In the event that your users device is lost, users employment is terminated, you don’t have physical access to the device but need to wipe it for security reasons – you can start a remote device wipe through your Outlook Web App under Settings > Mail > Options > Mobile devices and selecting Wipe Device. Within moments the device will be wiped clean of any data, content and settings and this works for both iPhone and Android devices (tables and phones).

Support Services

ExchangeDefender Pro offers users a VPN server to connect to in a secure manner no matter where they go. Public Wifi hotspots tend to have questionable security at best and can be used to compromise a device that is connecting blindly across the Internet. Connecting your phone automatically to a VPN can assure that email access (and all the confidential data in the email) can never be snooped on.

We are currently in beta with our mobile OTP/2FA applications which will further turn the mobile device into a part of your authentication so you don’t have to remember complex passwords at all. In the meantime, it’s important to let the users know what ExchangeDefender is currently capable of doing for them and to enable/configure those features so they are actively protecting every email user in your organization.

   Beta Launch: Managed Outbound Network Services

ExchangeDefender is proud to announce the beta launch of our Managed Outbound Network Services – interjecting support, monitoring, and management of outbound mail delivery services. If you’ve ever had to deal with outbound delays, deferrals, rejections, SMTP channel errors, etc we will now have the ability to assist you with email delivery and facilitate problem resolution for outbound email delivery in realtime.

One of the biggest problems in troubleshooting outbound mail problems is that problems are noticed days later, and are generally resolved well before a ticket is opened. The same goes for abuse, sometimes a mail blast is caught only after hundreds of messages have been sent and domain/sender had their reputation damaged.

    Tighter Restrictions Means Better Monitoring

Our new ExchangeDefender Managed Outbound Network Service involves tighter restrictions and better monitoring of email traffic by actual humans reviewing statistical models in realtime. This is not something that is possible through automation because it’s very difficult for computers to determine legitimate content from illegitimate or dangerous content. Sending patterns also change depending on the sender, time of day, day of the month, devices, etc. User may run a mail merge marketing campaign or invoice batch and send hundreds of messages in a very short period of time, blocking their access automatically would interrupt legitimate activity. By adding people to the mix, that can analyze the content and sending patterns we have the ability to stop outbound mail abuse the same way we do it on the inbound side.

Considering that almost 30% of our support time is dedicated to outbound mail delivery inquiries,
we expect this new solution to reduce our partners and clients time significantly.”

-Vlad Mazek, CEO ExchangeDefender

The best part about the new service is that it will be free and will require no configuration or management on our clients or partners behalf. Any notices we may have to issue to end users will automatically carry our partners or clients logo and contact information and will be resolved in realtime. Historically, we know that 90% of the time our clients are not aware of an issue at all, and we hope that the new service will reduce ongoing support and technical troubleshooting struggle our partners have had to go through regarding email delivery. By catching the issue in realtime, we will also help our partners appear more proactive and able to protect their clients better during 0-day infections and outbreaks. Additionally, we will be able to minimize the damage that a single careless user or hacker can cause an entire organization by stopping an outbreak at the source.

We will be writing more about this service in August and the first beta clients will be onboarded during the 2nd week of August – if you are interested in participating please send an email to beta@ownwebnow.com and let us know!
