Security

Ever since we committed to ExchangeDefender Phishing Firewall as a core feature in ExchangeDefender, we knew that the biggest user benefit will be a trusted cyber-security expert available as a part of the solution. ExchangeDefender redirects all links that pass through ExchangeDefender through our firewall, giving users that click on a suspicious link in their email more information about the suspicious site – for example, if you clicked on a link in an email from Bank of America and are actually going to a web site in Poland, it might be an issue. But who do you turn to when there is an issue?

ExchangeDefender Chief Security Officer is just a click away and so far we’ve handled over a thousand inquiries from our clients and partners. If you’re looking at a link and you cannot tell why we intercepted and flagged the content, just click on the yellow button and fill out a form.

Within 24 hours you’re guaranteed a response from our team. The turnaround average so far has been just 18 minutes!
What happens on the back-end is actually quite hands-on: first we investigate the original email and compare the context with the link target, location, etc. We then open the link in a sandbox (safe environment without additional network connectivity and no data) to see what sort of information the web site collects and attempts to send. We then rephrase it in a non-techie user-friendly way and help the client out.

We’ve been overwhelmed with both skepticism and compliments as a result – turns out most users do not expect a response and are pleasantly surprised when an actual human emails back with useful information. We’ve gotten compliments on our turnaround time, usefulness of information, saving the user from dangerous content, as well as thankful comments about the frustration that phishing in general creates – as we’ve been fine tuning xdref.com our users are seeing it less and less and when they do see it we are happy to help.

The overall value of the service cannot be overstated – we’ve saved our CIOs, partners, MSPs, IT guys and gals hundreds of hours in investigative work alone. We got our clients a security audit that allowed them to continue to work quickly. Not to mention about all the bad links that likely would have lead to a breach or security compromise – that the users and techs never had to deal with.

P.S. Included in ExchangeDefender Pro at no additional cost. If you’re still frustrating your clients with “training” programs/videos/whitepapers that SPAM filters catch and junk anyhow – stop wasting your clients time and moneyExchangeDefender Phishing Firewall is a better, more effective, more affordable solution.

ExchangeDefender Phishing Firewall has been a huge success in it’s initial roll out and I wanted to take a moment to bring you up to speed on our progress and our end goal: to eliminate phishing and spear phishing as a threat to our clients. I do not intend to mince words here, this is the #1 threat out there – 90% of all compromises and breeches start with a phishing email. Stopping it, as an email security company, is our #1 job and I’m happy to report that initial results are stunning.

Little bit of a rewind: Until now the most popular way to fight phishing and spear phishing was through “education” – there is an entire cottage industry of supposed “phishing education”, testing, refreshers – and it all revolves around training people to hover over links in Outlook, what not to click, what to read. It will not surprise you that such “training” is practically worthless, but they say that a picture is worth a thousand words so here is our phishing book:

In the 48 hours following 4th of July weekend in United States, dangerous links in the email were clicked on over 770,000 times.

Without ExchangeDefender Phishing Firewall, these links would have redirected our clients to dangerous sites that likely would have lead to a compromise or a security breach. So much for training.

What’s even more telling is that, even with our firewall in place, 164,000 people decided to proceed to a dangerous site anyhow.

If more than 1 out of 5 clicks in your email will take you somewhere dangerous, how well is your training performing?

With ExchangeDefender Phishing Firewall we are enabling companies to setup policies, restrict access, provide intelligence as the user clicks — and we provide logging giving you an idea who attempted to trash your organizations network.

The scary truth behind phishing is that training is only useful in blatantly apparent cases – the kind that will NEVER even get to your inbox. Our SPAM filtering detects dangerous email content and filters it out before it has a chance to get to your Inbox. The stuff that we can flag as dangerous – thanks to user reporting, audits, and look-ahead scanning is far more sophisticated than anything we could pack into a SPAM filter – and it gives your users real intelligence on what they are about to click on. You cannot expect users to remember all their training and to be a web security analyst – their job is acting on the email.

Our job, is making sure the emails get to them clean and free of dangerous malware. Once they click on the links in the email – we are going one step ahead – and leveraging our industry relationships (data feeds and infosec sharing of dangerous content) to make sure you know exactly what you’re clicking on.

Phishing is immensely profitable and far more effective than any other form of hacking – the user literally clicks and gives the hacker the keys to the network – and our ExchangeDefender Phishing Firewall helps remove the danger and reduces phishing to merely an annoyance.

The numbers speak for themselves.

Sincerely,
Vlad Mazek

ExchangeDefender Phishing Firewall continues to impress in terms of performance and user engagement – it’s catching dangerous content and keeping users safe from phishing attacks that often result in security compromises and breaches. Phishing accounts for over 90% of IT compromises, and as we’ve written before more than 1 out of 5 links our clients click on have lead them somewhere dangerous. With those numbers it’s clear to see why hackers are relying on phishing as the first and most effective form of attack – people will click on anything!!! And as intrusive as EPF seems to some (thank you for your feedback), our development team has been working overtime since the launch to make ExchangeDefender Phishing Firewall out of the way when it should be, and in your face when something dangerous shows up.

The goal of ExchangeDefender Phishing Firewall is to keep you safe from potentially dangerous sites and out of the way the rest of the time. You can keep up with our Dev fixes over at https://www.anythingdown.com and keep sending us your feedback. We love to hear it and we love improving the service so it can help keep you and your business safe. We also like to hear what you want us to add to the service that would make it more valuable. One such piece of feedback helped build a “Report Issue” feature:

If you click on something that you don’t recognize and you can’t tell what it is – DO NOT CLICK ON THE LINK – we are here for you. Our security concierge will open the link in an isolated virtual environment and see what kind of data is being sent back-and-forth. You will get a response, generally within minutes, with either a thumbs up or thumbs down. How cool is that?

Keep the suggestions coming, we love making ExchangeDefender Phishing Firewall the key part of your defense from phishing.

ExchangeDefender Phishing Firewall has had an outstanding first * X days * protecting our clients from phishing. While the roll-out of such a massive service is always going to be a challenge, we cannot be more thankful for our users and the relationship that has lead to tons of feedback, bug fixes, new features, and a meteoric rise in additional security that everyone enjoys.

Just as a reminder, ExchangeDefender Phishing Firewall is an always-on phishing protection for email and web. As someone emails you phishing content, in hopes that you’d click on it and give away credentials and download malware, ExchangeDefender both helps keep that email sanitized and quarantined so that it never gets to your Inbox to be clicked on. But that’s not a fool-proof process, nor is it realtime – a site that was safe when the email was sent could have just been hacked and dangerous content uploaded – but we’ve got you protected there too: when you click on any suspicious site in ExchangeDefender scanned messages you will be directed to our firewall site, instead of directly to the suspicious content. Once you’re there, you are further protected by your corporate policies, and you’re given additional information that helps you determine if the site is dangerous or not. Once you’re sure you can either whitelist or blacklist the site and you’ll never be interrupted again.

How cool is that? Well, it’s so cool that during just the first two (2) days of use, ExchangeDefender Phishing Firewall caught 770,000 clicks on suspicious sites that aren’t one of the top 5,000 Internet domains – and 164,000 requests proceeded to known dangerous stuff.
When you’re dealing with email and dangerous links, you need every bit of security and intelligence in your corner and ExchangeDefender Phishing Firewall delivers that:

It’s always on, always scanning your messages

There is nothing to configure, setup, install, or buy

It works on Outlook, Gmail, and any other email service

It protects you on your desktop, laptop, tablet, and anywhere else you click on links

It gives you a database of known dangerous/suspicious sites

It protects you by isolating patterns/data from ExchangeDefender’s reputation table

It secures you by leveraging data-sharing relationships we have with the worlds largest security vendors

It logs your activity so you can backtrack and identify dangerous activity

It gives your business ability to setup custom policies and block/allow access as needed

It gives you control over which sites to whitelist and blacklist so you’re not interrupted

It learns what you click on and how so you don’t have to manage a whitelist

Most importantly, it gives you access to our Chief Security Officer infrastructure where you can Report an Issue and have our team help evaluate a potentially dangerous link.

Not only are we doing everything to keep you safe and secure online, we’re literally available in person to assist when necessary. We know that every feature/block isn’t going to be loved by everyone, we know that every change can grind some folks the wrong way, we know that it’s not going to be perfect – but we’re in your corner, we’re here for you, and keep on sending us feedback so we can build this into a security service everyone loves as much as ExchangeDefender.

Thank you for your business and have a SAFE day on the Internets :slightly_smiling_face:

It is our pleasure to introduce you to the ExchangeDefender Phishing Firewall support services. While the launch of the XDPF has been rocky, we’ve received nothing but glowing reviews about it and the potential behind it to solve other email related issues (more on that in the webinar). Now that most of the dust is settled, we’re moving on to expanding this service to better serve and protect our users and the first feature out of the gate is the most obvious question a user would ask their IT/security person:

“Is this link safe to click on?”

Prior to ExchangeDefender Phishing Firewall deployment, nobody would even think of such a question. You clicked, and if you clicked on something malicious, boom you’re pwn3d. Now you’re presented with the link, the path, and you suddenly have a choice to make: “Do I trust this site?” – well, sometimes it’s hard to guess and we’re here to help. When you click on an HTML link, you will be taken to the ExchangeDefender Security Center and there will be a new yellow button there labeled “Report Issue”:

If you click on the yellow button you will be presented with a form to provide additional comments and contact information. After you provide the minimal required information, a service request will be sent to a human being at ExchangeDefender that will evaluate the link for you:

We will basically look at the link and the email data (sender, charset, SPAM data, reputation) as well as the link destination. The link will be opened in a virtual sandbox environment and we will look for any obvious payload that is automatically downloaded or data requested from the browser. We will then report back to you in an email within 24 hours and let you know what we found.

Obviously, we will also be using the same form for any support or issue management, basically setting up the ExchangeDefender Phishing Firewall as a managed, supported, and facilitated service end-to-end.

We will be discussing this feature in far more detail during the webinar on July 10th, 2019: https://register.gotowebinar.com/register/5418502553065819404 but in general terms this is a huge commitment to us that requires us to be available as a Security Officer whenever our clients need us. As a result of managing both the email and the web security incidents, we now have far more data and reputation information that can rely on to help secure our clients in near real-time. As it becomes harder and harder to know who to trust, businesses need security expertise and analysis provided on demand so they can get back to work – phishing is far too profitable and as the #1 attack vector leading to breaches and compromises, it is only going to get worse. With ExchangeDefender, you have a trusted partner that is there to help beyond just another automated security layer, our power is in the people.

ExchangeDefender Phishing Firewall goes online tomorrow, and we wanted to explain our policy and our implementation of the URL rewriting/redirection because it is a departure from a traditional IT hierarchy where organizational policies override group and user requirements.

Our goal with ExchangeDefender PF is to provide a level of alert and notification to our clients that is designed to provide additional information about the link they clicked on. As we scale this service out, that will be it’s purpose: Be aware of what you clicked on, and prepare for what you’re about to see. Phishing, and spear phishing in particular, is designed to be a convincing fraudulent identity theft of an organization you know and trust (your bank, your coworker, your vendors) and our goal is to help you discern if something is valid or not.

Our whitelist/blacklist implementation is in line with “we inform, you decide” mantra, as we cannot outright block you from actually going to the dangerous site. That is the responsibility of your IT department, your network management, and your organization.

How do Whitelists and Blacklists work?

In ExchangeDefender we have 4 sets of whitelists and blacklists: user, domain/organization, service provider, and global. Our global lists are automatically populated for our service providers and when they protect a domain with ExchangeDefender, those entries are applied on the domain/organization level, and further down to the end user. As we continue to monitor, manage, and get additional intelligence about dangerous sites we will continue to curate these lists as a part of the service.

For example, we might find out that *.vlad8150.microsoft.net is a Microsoft Azure instance that is attempting to spread malware. We will promptly add it to our global blacklist and that site will now be blacklisted for every ExchangeDefender user. When they click on a link that leads them to that domain, they will see the ExchangeDefender PF notice with the URL in red. User will then have the option of ignoring it and proceeding to the site, or adding it to their whitelist. If they whitelist a domain/web site, any future requests will bypass ExchangeDefender PF web site and automatically redirect to the target URL.

The hierarchy of whitelists/blacklists is as follows, whichever rule is defined on the top is the one that is applied to the user when they click on a link.


But why, why not implement policies like NTFS, access list, or any other policy in which global deny rules override end user policies?

Simply put: Traffic blocking should be done on the network level. We are simply the alert service, we will advise you when we see something dangerous and it’s up to you to discern if the site is trustworthy or not. We believe that this implementation will cause the least amount of interruption to the day-to-day use.

That said, we have been working on additional controls and policies to help our service providers and CIO’s better enforce company security policies. As with everything, security policies must be implemented in layers – and dangerous content should be enforced in accordance to business requirements. This means that if your clients should not be downloading .exe files, the network firewall should be doing that. We don’t have the means to do that as an email service – users can right click on the email, put it in notepad, remove https://r.xdref.com/url= from the link and go straight to the web site.

How do we manage them?

ExchangeDefender PF whitelists are available at every level of ExchangeDefender. Simply add a site to either a whitelist and blacklist and ExchangeDefender will automatically propagate your rules down through the entire organization. Users will have the ability to add / block sites from the ExchangeDefender PF in real-time and their settings will be preserved in their account only.

Service Provider Level
Domain Level

P.S. Officially the service goes online tomorrow, unofficially it’s been in place for months we just haven’t rewritten a single URL except for the emails you received from us – we have worked very hard on the implementation and we don’t expect major problems but will have staff on hand around the clock to address any issues immediately. Spear phishing is an epidemic, over 90% of compromises start with a link in an email. We will handle any glitches, bugs, and issues as fast as possible and have full confidence that having an alerting service with potential problems is far more useful than having nothing and leaving clients exposed.

ExchangeDefender is thrilled to announce the new Phishing Firewall in the cloud, going into full production – Wednesday, June 12th, 2019 for all ExchangeDefender Pro and Enterprise protected clients. The old way of highlighting, underlining, inserting warnings and so on will be removed from the service at the same time because it lacks the ability to protect clients in real-time.

The ExchangeDefender Phishing Firewall (EPF) is a real-time, active pishing protection. As ExchangeDefender processes inbound mail, it will rewrite every link to proxy it through EPF when user clicks on it. If the site is safe, the user will be automatically redirected to it and will not even know that EPF is in the way. If the site is not on the safe list, end users will see this warning:

They will have the option to just click on the link and proceed, add to whitelist (at which point they are automatically allowed through in the future) or add to blacklist.

Because of the way phishing works, and all identity theft or forgery in general, it is impossible to secure email messages in transit without making annoying modifications to the message that often distort the look and feel of it. Majority of those links are in the 95% of the mail that passes through ExchangeDefender as SPAM/SureSPAM, meaning that they would never even be seen by anyone. By moving the Phishing Firewall to the cloud, we can now secure every device and provide additional metrics and advisory on top of it to protect our clients from 0-day exploits.

This feature is provided to our clients free of charge and replaces expensive “security awareness training” solutions that users typically hate and do nothing to adequately secure the client. With Exchange Phishing Firewall we enable our clients to create custom policies, maintain whitelists, blacklists, get enterprise reporting and more. It further allows us to go one step beyond – in the upcoming releases we’ll offer the ability to display a screenshot of the site as well as link intelligence data (How long ago was the domain name registered? Where is the IP you’re about to go to located? Is the domain a close spelling error of a widely recognized site? Is the forged site just a cloud hosted Google, Microsoft or Amazon cloud service instance that is holding or redirecting you to another more dangerous location?)

If you’re currently on ExchangeDefender Essentials, we encourage you to schedule a demo with our team to check this feature out as it’s significantly cheaper than antivirus or “security training” solutions and will do a far better job. If you’re on ExchangeDefender Pro or ExchangeDefender Enterprise, you will get this feature free of charge. On Monday, June 10 we will send an email notification announcing this launch to our partners, MSPs, and Service Providers. On Tuesday, June 11 we will send an email notification to end users. Finally, on Wednesday, June 12th we will go live with the service and hope to minimize the annoyance of phishing once and for all. Email is the single most popular attack vector, with 91% of the compromises starting through a phishing attack, and we look forward to protecting all our users even better.

This Thursday, June 6th, we will be announcing a major overhaul in the way we deal with spear phishing SPAM. No, it’s not a mind-blowing patent-pending stroke-of-genius sort of stuff, it’s much closer to what your parents told you growing up: Don’t get into a car with strangers don’t click on links or open attachments from strangers.

In a way, ExchangeDefender has had protection from this issue for years. If you had a decent IT Solution Provider implementing ExchangeDefender for you, they would have setup your SPF record and eliminated this issue – but many don’t. Or they would have turned on ExchangeDefender protection where all messages spoofing/forging your domain would automatically get junked – almost none of them do. Which is why ExchangeDefender as a service has become less of an IT tool and more of an end user suite of services to get stuff done.

When features like this are left disabled “because they might become support issues” it becomes really difficult to secure users. But I get it, IT companies have a business to run too, which is why we’ve really stepped up our support efforts and are going to be there to help folks get things done without becoming an additional problem for the IT department. Doing so has really made us rethink how we implement features and how the service behavior needs to speak the same language as the end user. Which brings me to phishing beyond forgeries.

Can you spot a stranger?One of the new phishing protection features in ExchangeDefender will allow you to flag messages that are coming from outside of your organization. You will have two settings – to modify the subject and to modify the header of the message so when you look inside of your mailbox you’ll know what came from a stranger right away. Try it:

Even from the message listing you’ll know which messages shouldn’t even be opened. But suppose you ignored even that – you can set another warning, printed inside of the message, giving the user even more of an instruction of what to do.

Warning: Message was sent from outside of the organization. Do not click on links or open attachments if you don’t recognize the sender.

Far from subtle. And it has to be – because most people check email quickly, between tasks, or are simply interrupted by it. ExchangeDefender has your back, and we’ll make sure we alert you to possible issues before they become problems. Which we hope everyone will be aboard with.

Please join us, June 6th at Noon, for our NEW webinar featuring ExchangeDefender’s Phishing and Spoofing protection, plus see what’s new with Encryption, WFS, and Wrkoo!

It’s no secret to anyone that’s been paying attention to this space that ExchangeDefender is getting a lot more user friendly – both in service and in design. We’ve been improving the way we communicate with our clients and our partners through efforts like embedded help, in-line training and support, real-time chat support, self service portals, NOC sites, etc

Next week we will launch a major feature in ExchangeDefender. It will address one of the biggest pain points in email security and it will give users a ton of control that will help close what is currently the biggest exploitable hole in email security: spear phishing. This will require us to give users a heads up about what they are about to see and training/documentation about how to use it to the fullest.

Which is where we have to make sure our partners are a part of the process too. During the webinar we’ll go over the details about how to insert branding and a message/note at https://admin.exchangedefender.com. This is generally not a big issue, since almost all of our partners would rather have us do more work for them than less, but if you’re really sensitive about this topic make sure you’re in the webinar to see what options you have and how to best leverage them for your own business purposes.

Looking forward to showing you all of this, and the redesigned ExchangeDefender Encryption product on June 6th at noon. https://register.gotowebinar.com/register/198414968804117507


ExchangeDefender is opening a wider beta test of our whitelisting functionality, which allows IT Solution Providers to whitelist sender mail servers that have broken DNS (missing PTR, mismatched A/PTR records) and poor sender reputation (hosts listed on multiple RBL blacklists).

If you have a sender you would like to whitelist against these essential network tests, please open a ticket at support.ownwebnow.com with subject “Whitelist PTR/RBL: IP Address” and provide as much information in the ticket so we can accommodate this specific request. Only hard non-negotiable rejections to whitelist will be for unknown address space and dialup/consumer cable IP addresses (because due to their nature those are typically dynamically assigned address spaces that shouldn’t be relaying mail at all, they should be using their ISP mail server provided smarthost)

Requests will be reviewed and either approved (and enrolled) or rejected within 24 hours by our CSO.

Background: Inability to previously whitelist broken DNS and dynamic IP address space is rooted in our mission statement. We are here, beyond everything else, to help secure the email. We know our partners, IT Solution Providers, VARs, MSPs, etc do not have the skill set, the time to properly research underlying issues, enough data and statistical models to evaluate sender IP reputation, or even the incentive to discern how big of a security threat and compromise a specific IP address with broken DNS or poor reputation may pose to your client.

In fact, you pay us to worry about those things and keep your clients secure. But, sometimes clients like to think they know better than their technology experts, generally accepted security standards on the Internet, and ExchangeDefender. And the client is always right. But, when they get infected attachments, broadcast storm, password dumps, or other security compromises because they insisted on lowering their security – then ExchangeDefender is on the hook for securing them. And we don’t get to say “told you so” nor do we have any rapid means to fix the issue.

Since my retirement, all of those hard-line policies designed to keep clients safe beyond whatever “specific business case requirement” they may have, are slowly going away. Good news for the client, good news for the partners. Good news for us, because going forward we will start providing Email Security Engineering services – so when you get a security compromise or an usual issue and you’ve asked us to compromise your security – we will be able to address the issue on your behalf.

I choose to look at this as a positive – we will help our clients meet their business needs and get the mail they desperately need – and if something breaks we will be there to help assist with the cleanup (for a fee, of course). This, among many other service related things, is just the part of the ExchangeDefender being more responsive and service oriented when it comes to our clients demands as opposed to our expert opinion as a security policy.
