An attacker sends a phishing email to lure an end user within an organization into clicking a malicious link, opening an attachment, or providing login credentials. Once the attacker lands on the victim’s machine, what’s their first move? They’ll likely figure out their position within the organization, scraping the memory for cached information. This can include temporarily stored admin credentials, connected file shares, domain controllers, browsing history of SharePoint resources, and virtually any means to become a local or domain admin.
For the attacker, moving laterally and building a foothold is key at this stage to stay persistent. Gaining privileged access allows them to access infrastructure, on-prem networks, cloud, and SaaS applications. It’s also a prime location to launch phishing or social engineering scams, enabling access to other employees or partners.
Once the foothold is established and expansion achieved, executing objectives becomes the focus. This might involve stealing intellectual property, sensitive data, transferring funds, or causing business disruption through ransomware. Skilled attackers will do what they can to cover their tracks, often using ransomware as an effective diversion to encrypt evidence.
Most companies lack the skills to keep up with emerging threats. For example, you wouldn’t hire a plumber or electrician full-time just because there might be a pipe blockage or power outage, right? Managed Detection & Response (MDR) services are designed to stop attackers by covering multiple attack surfaces and phases in the cyber kill chain. These technologies often include EDR, XDR, NDR, CDR, SIEM, and SOAR. But one component often overlooked is Email security.
Email security is often the unsung hero in the fight against cyber threats. While technologies like EDR, XDR, NDR, CDR, SIEM, and SOAR are commonly associated with MDR services, Email security is frequently left on the sidelines. Yet, it’s a vital piece of the puzzle.
Email is the starting point for around 90% of cyber-attacks, and a single phishing email can lead to significant data breaches. Ensuring that your MDR service focuses on identifying and mitigating phishing attempts is key to reducing risks like data loss, unauthorized access, and other security incidents.
Successful phishing attacks can wreak havoc on business operations, leading to compromised user accounts, network infiltration, malware infections, or ransomware incidents. MDR services must leverage advanced techniques to identify and block phishing emails promptly, minimizing potential impacts on business continuity.
