How to Protect Your Business from Phishing: A Practical Guide for 2026

Your accountant received an email from “PrivatBank” urgently requesting account verification. The email looks perfect — logo, signature, even the link seems legitimate. One click — and attackers now have access to your credentials.

This is not a hypothetical scenario. This is a real incident that we at IT-Premium investigated last month.

Phishing in 2026: Why It’s Problem #1

Phishing remains the most common cyberattack vector globally. According to the Verizon Data Breach Investigations Report, 36% of all data breaches begin with a phishing email. For small and medium businesses, the situation is even worse — they rarely have a dedicated security team.

In Ukraine, the problem has intensified since 2022. The war created perfect conditions for phishers:

  • Emotional pressure — emails about “mobilization,” “data evacuation,” “urgent payments” work flawlessly
  • Remote work transition — less oversight, more personal devices
  • New government services — Diia, eSupport, Reserve+ became targets for fake websites

According to CERT-UA, over 4,000 phishing campaigns targeting Ukrainian organizations were recorded in 2025. And those are only the registered cases.

Anatomy of a Phishing Attack: How It Works

Understanding the mechanics helps recognize threats. A typical phishing attack consists of several stages:

1. Reconnaissance

The attacker gathers information: employee names from LinkedIn, company structure, email format ([email protected]). The more public information available, the more convincing the email.

2. Bait Preparation

An email or message is created that imitates a trusted source: bank, tax authority, supplier, colleague, or manager. In 2026, attackers actively use AI to create perfect replicas.

3. Delivery

The email reaches the inbox. Modern phishing emails bypass basic spam filters because they lack classic spam indicators.

4. Exploitation

The victim clicks a link, enters credentials on a fake website, or downloads a file. Often, a single click is enough.

5. Persistence

Once inside, the attacker acts fast: exfiltrates data, installs malware, or prepares server encryption.

5 Types of Phishing Ukrainian Businesses Face

Mass Email Phishing

The classic variant: mass mailings impersonating banks, government services, or popular platforms. Low quality, but effective through volume.

Example: An email “from Ukrposhta” about an undelivered package with a tracking link. The link leads to a copycat site requesting card details.

Spear Phishing (Targeted)

An attack on a specific person or company. The attacker knows the name, position, and work context. Far more dangerous than mass phishing.

Example: An email “from the CEO” to the accountant urgently requesting payment to a new supplier. The email looks internal, and the tone matches the executive’s style.

BEC (Business Email Compromise)

A real employee’s or partner’s mailbox is compromised. Emails come from a legitimate address — nearly impossible to detect.

Real IT-Premium case: A trading company’s supplier manager email was compromised. New bank details were sent from their address. The company transferred UAH 280,000 to a fraudulent account.

Vishing (Phone Phishing)

Calls from “bank security,” “Microsoft support,” or “tax authorities.” Especially prevalent in Ukraine since the full-scale invasion.

Messenger Phishing

Viber, Telegram, WhatsApp — new channels for phishers. Messages from “Diia,” “eVorog,” “volunteers” with links to malicious sites.

How to Recognize Phishing: Checklist for Every Employee

Print this list and post it at every workstation:

🔴 Urgency. “Immediately!”, “Within 24 hours!”, “Your account will be blocked!” Real organizations rarely pressure with urgency.

🔴 Unknown sender. Check the full email address. [email protected] and [email protected] differ by one letter.

🔴 Mismatched links. Hover over the link (don’t click!) and check the actual URL at the bottom of the browser.

🔴 Request for confidential data. Password, card number, SMS code — no legitimate organization requests this via email.

🔴 Attachments from unknowns. Especially .exe, .zip, .docm files. Even PDFs can contain malicious code.

🔴 Grammar errors. Though AI makes this less reliable as an indicator, it still occurs.

🟡 Mismatched tone. If the “CEO” suddenly writes in an unusual style — verify through another communication channel.

🟡 Unusual request. Changed bank details, urgent payment, system access — always confirm by voice.

Technical Protection: What Every Company Must Have

Employee training is only half the solution. The other half is technical measures that block phishing before it reaches a person.

1. Email Authentication (SPF, DKIM, DMARC)

These three protocols are the foundation of corporate email protection:

  • SPF — defines which servers may send emails on behalf of your domain
  • DKIM — adds a digital signature to every email
  • DMARC — specifies what to do with emails that fail verification

According to our data, only 23% of Ukrainian SMBs have properly configured DMARC. The rest are open targets for email spoofing.

2. Multi-Factor Authentication (MFA)

Even if a phisher obtains a password — without the second factor, they can’t log in. MFA reduces account compromise risk by 99.9% (Microsoft data).

Minimum: MFA on email, VPN, accounting systems, cloud services.

Recommendation: Use hardware keys (YubiKey) or authenticator apps. SMS codes are better than nothing but vulnerable to SIM-swapping.

3. Email and Web Traffic Filtering

Modern solutions analyze:

  • Links in real time (sandbox verification)
  • Attachments for malicious code
  • Sender reputation
  • Anomalies in email headers

4. Endpoint Detection and Response (EDR)

Antivirus is no longer sufficient. EDR solutions track suspicious behavior on devices: unusual connections, privilege escalation attempts, mass file copying.

5. 3-2-1 Backup Rule

If phishing leads to encryption — backups save the business:

  • 3 copies of data
  • 2 different media types
  • 1 copy offsite (cloud or another location)

What to Do If Someone Clicked

An incident has occurred. The employee realized they clicked the wrong thing. Every minute counts now.

First 5 minutes:

  1. Disconnect the device from the network (Wi-Fi, Ethernet)
  2. Do not shut down the computer (preserve evidence in RAM)
  3. Notify the IT department or IT provider

First hour:

  1. Change passwords for compromised accounts from a different device
  2. Review login logs for unauthorized sessions
  3. Block suspicious IP addresses on the firewall

First 24 hours:

  1. Scan all network devices
  2. Check for lateral movement
  3. Report to CERT-UA (if the incident is serious)
  4. Document the incident

Employee Training: How to Do It Right

A one-time lecture doesn’t work. An effective anti-phishing program includes:

Regular simulations. Send test phishing emails monthly. Track who clicks. Train those who fall for it.

Short micro-trainings. 5-10 minutes every two weeks. Real examples from the Ukrainian context work better than abstract slides.

Positive reinforcement. Praise those who report suspicious emails. Create a culture where reporting is valued, not seen as paranoia.

Simple reporting channel. A “Report Phishing” button in the email client or a dedicated messenger chat.

Cost of Protection vs Cost of an Incident

Typical costs for basic anti-phishing protection for a company with 20-50 employees:

Measure Approximate Cost
SPF/DKIM/DMARC setup UAH 2,000 - 5,000 (one-time)
MFA for all accounts UAH 0 (built into most services)
Email filtering (cloud) UAH 500 - 2,000/month
Staff training UAH 3,000 - 8,000/quarter
Annual total ~UAH 30,000 - 60,000

Average cost of a single phishing incident for Ukrainian SMBs (our data): UAH 150,000 - 500,000. This includes downtime, recovery, lost data, and reputational damage.

The math is simple: protection costs 3-10x less than a single incident.
