Why Darktrace?

Attacker-centric security isn't the answer. Organization-specific is.

Threat story: Phishing

How we stopped an attempted Dropbox phishing attack

Item A
Item B
Item C

Initial infection

Threat actors used Dropbox to send phishing emails with a PDF containing a malicious link, bypassing traditional security since both the sender and hosting service were legitimate.

Darktrace identified the unusual sender behavior, held the email, and later locked the link to prevent access.

Credential harvesting

An employee bypassed security measures and accessed a fake Microsoft 365 login page designed to steal credentials, which traditional tools failed to block.

Darktrace detected the unusual domain connection and flagged the activity for investigation before further escalation.

Account takeover

Attackers used stolen credentials to log in from VPN-masked locations, bypassing MFA and evading standard security tools that trust valid tokens.

Darktrace detected anomalous logins and alerted security teams to the compromise.

Lateral movement and phishing

The compromised account created hidden inbox rules and sent phishing emails, tactics that blended into normal activity and evaded detection.

Darktrace flagged the unusual mailbox rule changes, and if Autonomous Response had been enabled, it would have disabled the account immediately.

Platform security

Protect against attacks that traverse your digital environment

A phishing message or email is often only the start of a targeted campaign to compromise a network or account. Through taking a defense-in-depth approach, Darktrace ensures that phishing can’t spread across the digital estate.

Phishing

Frequently asked questions

Item A
Item B
Item C

What is a phishing attack and how does it work?

A phishing attack is a cyber threat where attackers impersonate trusted sources (like banks, brands or known entities) to trick users into revealing sensitive data. These emails often include malicious links or attachments and can lead to data breaches or financial loss. Anti-phishing services use automation and AI to stop these threats before they reach inboxes.

What are the most common types of phishing attacks?

Some common types of phishing attacks are:

• Email phishing: Generic fake emails.

• Spear phishing: Targeted messages using personal info.

• Whaling: Aimed at executives or high-value targets.

• Credential phishing: Fake login pages to steal credentials.

• Smishing/Vishing: Phishing via SMS or phone calls.

What is the impact of AI on phishing attacks?

AI can make phishing emails more convincing by mimicking human tone and style, and it lowers the barrier to entry for creating these types of campaigns. On the other hand, it also powers AI anti-phishing protection, which can analyze email behavior and intent to detect phishing emails that traditional filters miss.

How does Darktrace detect phishing emails?

Darktrace uses Self-Learning AI to understand the unique “pattern of life” for every user and device in an organization. It then detects phishing emails by identifying subtle anomalies in behavior, content and tone – even when threats originate from trusted domains or don’t contain known signatures. This allows Darktrace to catch both known and novel attacks in real time.

What actions does Darktrace take on phishing emails?

Once a phishing email is detected, Darktrace/Email can take targeted actions such as holding the email, rewriting or locking malicious links, or stripping dangerous attachments. These actions are automated and adaptive, minimizing disruption while neutralizing the threat before a user engages.

How can employees be trained to spot phishing attempts?

Darktrace enhances user awareness by inserting real-time banners that explain why an email is suspicious, helping to educate users as they interact with messages. With this context, the user can then decide whether to report the email to the security team, an approach which results in 60% fewer benign emails reported.

How does Darktrace deal with advanced phishing threats? (i.e. social engineering, QR codes, multi-stage payloads)

Darktrace is uniquely equipped to detect and stop advanced phishing tactics such as social engineering, QR code phishing (quishing), and multi-stage payloads. Its AI analyzes content, context, and communication history – not just links or attachments – to spot threats that bypass traditional filters and sandboxing tools. Its advanced link detection capabilities can also identify the malicious content behind links, even if they lead to a trusted domain.

How does Darktrace prevent credential phishing?

By recognizing unusual login patterns, redirect behaviors, or abnormal email requests, Darktrace / EMAIL detects credential phishing attempts even when links lead to seemingly legitimate sites. If credentials are stolen and a user is compromised, it can also identify the signs of an account takeover and take automatic action.

How does Darktrace ensure phishing doesn’t spread across the digital estate?

Darktrace takes an ecosystem-wide approach. If a phishing attack bypasses the inbox and spreads into a user account, Darktrace’s coverage of outbound email activity, lateral movement, login activity and SaaS accounts prevents the attack from spreading. Darktrace / EMAIL also integrates with the rest of the digital estate via the Darktrace ActiveAI Security Platform, which shares AI insights to improve detection for the whole enterprise.
