Cybersecurity Fatigue: Is Your Business at Risk?

/in , ,

Security fatigue is real. You’ve felt it, and so have we. Cyber criminals know this, and they are waiting to capitalize on it. When we let security fatigue guide our decisions and allow our guard to drop, we become much more likely to fall victim to a cyberattack.

Over the past few weeks, we have assisted multiple companies that fell victim to such attacks. These events reflect a recent surge in cyberattacks, serving as a harsh reminder that we must remain vigilant.

Common Elements

Each of these recent cases shared three common elements:

  1. An employee clicked on a malicious link and shared account information.
  2. The company opted not to deploy recommended security measures.
  3. Neither the business or IT leaders had a plan for how to respond to an emergency.

These elements demonstrate critical failures at every phase of a cybersecurity event.

Prior to The Event

Even as small businesses, we are more vulnerable to cyberattacks than we may expect. A basic suite of cybersecurity services is no longer optional, it is essential for defending and protecting against attacks.

In each of the cases we recently handled, simple and effective baseline tools were not in place. Decisions made to avoid the incremental cost of added protections left these businesses exposed.

Consequently, each company is now paying a much larger price, ranging from several days of downtime and lost productivity to potential fines and litigation.Connect with a Cloud Advisor

The Event

Human action triggered all three of these recent events. While it is easy to claim that the individuals involved should have known better, the reality is that even knowledgeable people succumb to these tricks when they are tired or distracted.

How many times have you replied to or acted on an email that you skimmed or quickly read without focusing on the content? We are all busy, and an email often feels like just another task to check off.

When you combine a false sense of security with a momentary lack of attention, it is very easy to click the wrong link, enter credentials into a fake site, or share private information.

Technology is vital for protection, but your people must also understand the risks. They should be able to identify suspect interactions and know exactly what to do when faced with a suspicious email, text, call, or web page.

After The Event

In every recent event we have handled, the business and IT leaders were unsure how to proceed. Given the urgency and stress of the moment, none of them referred to an existing Information Security Plan because they did not have an incident response checklist or strategy in place.

We tend to focus on recovery, such as getting systems back online and restoring data. While this is an urgent and tangible response, it is only one part of the equation.

Your cyber insurance carrier may need to verify your security measures, conduct a forensics analysis, or direct your recovery efforts. You likely have legal, industry, or contractual reporting requirements, and you may even need law enforcement to investigate.

Response and recovery from a cyberattack requires having the technology in place to get your systems, apps, and data back in operation as well as having resources in place to get you through the legal, regulatory, contractual, marketing, and customer relationship challenges you will face.

Service Update: Advanced Threat Protection

/in ,

Service Update Announcement

Beginning July 1, 2022, Cumulus Global is adding Advanced Threat Protection services to all clients using Microsoft 365 and Google Workspace.

With more than 40% of cyber attacks targeting small businesses and two thirds of attacks using email, Advanced Threat Protection is no longer an option. The stakes are too high. Recovery takes an average of 21 days and 60% of small businesses fail within six months of a successful attack.

To minimize the impact, we are waiving the standard setup fee and discounting the service by 20% for customers with an annual commitment. The fee will be reflected on your annual invoice or monthly invoices, as appropriate.

You may opt out of the Advanced Threat Protection service. To opt-out, please notify us by email prior to May 25, 2022. If you elect to opt-out, please review the terms of our Service Level Agreement as posted on our website.

Please contact us or schedule time with one of our cloud advisors if you have any questions.

Different Types of Email Security Features

Different Types Of Email Security Solutions Can Help Protect your Business

When launched Cumulus Global 15 years ago to provide small and midsize businesses (SMBs) with email security and security solutions. As early adopters, we saw how managed cloud services and solutions made enterprise grade solutions affordable and effective for small businesses.  While much as changed over the past decade and a half, we still face email-based threats.

Email Attacks are Easy

According to Verizon’s 2021 Data Breach Report, email remains one of the most common vectors for attacks. And, phishing attacks are at the top of the list. Email phishing attacks remain prevalent because they are relatively easy. Cyber attackers are able to say one step ahead of our defenses, in large part to the rise in social engineering. With more of our personal information available through social media, attackers can use psychological tactics and personalized messaging to target specific individuals (spear phishing) and business leaders (whaling). In doing so, they garner sensitive information and gain access to systems and data.

Business Email Compromise

Business Email Compromise (BEC) attacks impersonate your email domains or emails for specific users. In most instances, BEC attacks look and feel like legitimate emails from your business. Combined with social engineering tactics and personalize information, they are hard to spot and often successful.  Cyber security attacks can be “internal” that target your employees, or “external” that use your business to defraud your customers and associates.

Email and Domain Impersonation

Preventing email and domain impersonation attacks bypass account level security, including multi-factor authentication. To prevent these attacks, recipients should only accept email that can be authenticated as coming from your domain.

Different Types of Email Security Protection: Good, Better, Best

Currently, you have three levels of email domain security that can protect your business and your identity: Good, Better, and Best.

Good: SPF Sender Policy Framework

SPF verifies emails sent from valid IP addresses, either from your domain or authorized senders. While most small businesses have an SPF record configured, errors cause individual emails, or emails from marketing and CRM systems, to be flagged as spam by the recipient. Cyber attackers can spoof email addresses to give the appearance of a validated sender.

Better: DKIM DomainKeys Identified Mail

DKIM verifies that have been digitally signed by the sending domain, or by services sending email on behalf of the domain. Proper configuration is technical and involves cryptographic key management; errors can lead to fake messages with valid DKIM signatures. Cyber attackers can remove the DKIM signature using sophisticated relay attacks.

Best: DMARC Domain-based Message Authentication, Reporting,
and Conformance

DMARC authenticates email origin by aligning identifiers from SPF and DKIM, and instructs recipients to deliver, quarantine, or reject failed emails by policy. DKIM helps improve email deliverability. Is the best protection against email and domain impersonation attacks, whether they target your employees, vendors, or customers. Reporting enables you to see email sources and manage your policies.

Protect Your Business With Our Email Security Services

While you set up SPF and DKIM with DNS record entries, DMARC is best implemented as a service. Doing so provides you access to settings, reports, and analysis tools. For most small and midsize businesses, the level of protection DMARC provides is worth the minimal cost.

EFail Flaw: Encryption Alone Does Not Protect Your Email

/in ,

Email EncryptionAs reported last week by eWeek and others, researched found two flaws that allow hackers with access to email accounts to read emails encrypted with OpenPGP and S/MIME.  This is significant for two reasons:

  1. These standards are available for us in almost every email client
  2. Budget-conscious users often relay on public-domain or free tools to use OpenPGP or S/MIME for email encryption

As noted in the eWeek article, 23 of 35 email clients tested as of the publication date were vulnerable.  While the actual risk from EFail is currently moderately low — hackers need access to the encrypted emails before they can exploit EFail, the rate of identity compromise is on the rise. Secondary threats, such as EFail, will become a more prominent form of attack in the future.

Free Encryption Solutions Often Lack Sufficient Protection

Robust email security and encryption services include features, such as validation of digital signatures, that ensure the integrity of encrypted email messages.

Furthermore, solutions, like ZixEncrypt, control both ends of the encryption process, so any messages (with or without S/MIME encrypted attachments) with an invalid or missing digital signature get bounced. Integrity checks prevent the delivery of compromised messages, thereby preventing exposure.

As you face an increasing need to secure email communications, the robust features in services like ZixEncrypt create a value proposition most businesses cannot and should not ignore.
