As companies increasingly rely on cloud-based email platforms like Microsoft 365 email security, cybercriminals have found increasingly sophisticated methods to penetrate email security. The 2024 Domain Security Report clearly illustrates this trend, illustrating how hijacked domains can bypass email defenses to target organizations. Of the techniques being wielded by attackers today, domain hijacking is one of the most pervasive. It allows an attacker to impersonate trusted contacts and do serious harm, combining trust in familiar domains with the scalability of cloud email security services.
Understanding the Risk: How Hijacked Domains Threaten Cloud Email Security
It is highly dangerous for cloud-based email systems because such domains appear to be perfectly valid, thus easily bypassing traditional filters while misleading users and security teams. Herein is a more critical look at how these kinds of attacks usually unfold:
Phishing Attacks: Cyber crooks use compromised domains to send convincing emails to dupe victims into releasing sensitive data. The domains sound so familiar that they bypass basic security filters and easily surprise victims.
Malware distribution can include hosting malware on the hijacked domains or offering links directly to malware. This leads to users downloading harmful files or accessing websites compromised by malware, which will appear harmless.
DNS: Cybercriminals impersonate the senior executive or supplier to demand via wire transfer, using fake domain names that sound legitimate enough, thereby creating an environment for extensive losses. Attackers exploit “dangling DNS vulnerabilities”, taking control of unprotected subdomains through this technique and hosting malicious content in what appears to be trusted domains.
Risks Associated with Hijacked Domains
Business email compromise scams resulting from domain hijacking generally result in wire transfers or payments to unauthorized accounts, consequently forcing organizations to incur immense financial losses. Cybercriminals employ domain impersonators in furtherance of efforts meant to bypass protection extended by cloud email security services and dupe employees into wiring money to an unknown account.
Beyond financial repercussions, hijacked domains can have lasting detrimental reputations. When customers or partners begin receiving spam emails from domains that appear familiar to them, their trust in cloud email security services quickly diminishes; this erosion of trust often has long-term ramifications that may prove hard to repair.
Hijacked domains can serve as entryways to data breaches. Phishing attacks targeting Microsoft 365 email security services often expose sensitive information, putting companies at risk of compliance violations and legal complications. To avoid these breaches, proactive domain security measures must be in place.
According to the 2024 Domain Security Report, third parties registered 80% of web domains that closely resemble well-known brands. Many of these contain active MX records that could make them attractive targets for attackers, thus demonstrating the need for vigilant monitoring of hijacked domains as part of Microsoft 365 email security services.
Best Practices for Protecting Domains From Hijacked Activity
Implement Secure Protocols:
- Registry Locks: Essential to Microsoft 365 security, registry locks help maintain the integrity of your domain.
- DNSSEC-DNS: DNSSEC authenticates DNS responses, prevents hijacking attacks on DNS domain names, and offers essential email protection.
- CAA Records: Set forth which certificate authorities can issue certificates to your domain, decreasing the risk of an attacker obtaining unauthorized domain certificates.
Enhance Monitoring and Layered Security
Layered defense strategies employ several protocols at various detection points to increase cloud email security, such as DMARC, DNSSEC, registry locks, and real-time monitoring.
Continuous Monitoring quickly detects any unapproved changes or abnormal activity on an IT network, providing real-time alerts that allow IT teams to act swiftly against suspicious activities and potentially mitigate damage caused by them.
Predictive Modeling uses algorithms to track domain activity patterns, aiding administrators in managing Microsoft 365 email security services through proactive threat detection.
Strengthen Cloud Email Security Protection
Effectively combatting hijacked domains requires taking proactive protective steps. Use tools like DMARC, registry locks, and continuous monitoring to add multiple layers of security; advanced email security services make these threats easy to manage while providing user and data safety. Explore cloud email security solutions to discover how adding extra protection measures could make a substantial difference in protecting users and data against hijacked domain attacks.
Microsoft 365 Email Security Services and cloud email security services can help protect your organization against the increasing threat of hijacked domains, upholding trust while guaranteeing integrity in digital communications.
