Three Fundamentals for Shoring Up Phishing Defenses

Phishing -- one of the oldest pain points in cybersecurity. Also known as pre-texting, phishing continues to wreak havoc quietly and is as significant a threat as ever.

Despite often being overlooked, phishing has been a mainstay in the cybersecurity threat landscape for decades. In fact, 44 percent of cyberattacks in 2024 featured phishing or pre-texting, while 85 percent of US organizations experienced a successful phishing attack last year alone. That means that phishing is one of the most dangerous “action varieties” to an organization’s cybersecurity health. As a result, the need for proper anti-phishing hygiene and best practices is an absolute must.

With that in mind, here are a few quick best practices and tips to help you recognize and deal with phishing threats.

Know the Red Flags: Emails

Phishers are masters of making their content and interactions appealing. From content design, layout to language, it can be difficult to discern whether the content is genuine or a potential threat, which is why it is so important to know the red flags.

Awkward and unusual formatting
Overly explicit call-outs to click a hyperlink or open an attachment
Strange requests concerning an account, system, or application changes with no prior awareness
Requests for personally identifiable information or your login and password
Subject lines that create a sense of urgency

These are all hallmarks that the content you received could potentially be a phishing attempt and indicate that it should be handled with caution. Most organizations will communicate multiple times and well in advance of any application transitions, and they will provide websites and other supporting materials and contact information for more details.

All suspicious emails can be sent to GW IT Security at abuse@gwu.edu, and questions about the content or requests in an email can be verified with the GW IT Support Center at 202-994-4948.

Verify the Source

Phishing can occur in a variety of ways. In addition to email, phishers ply their craft through phone calls, text messages, sometimes regular mail. Often, phishers will try to impersonate someone you may already know -- such as a colleague, service provider, relative, or friend to trick you into believing their message is trustworthy.

Don’t fall for it. If you sense that something about an email, phone call, or text message may be out of place or unusual, try to confirm whether the content is authentic and safe. If not, immediately break off communication and flag the incident through the proper channels (at GW, this is forwarding the message to abuse@gwu.edu).

Vishing and Other Phishing Offshoots

Greater awareness about phishing has spawned more diverse phishing efforts beyond traditional email scams.Phishers have adapted, expanding their techniques to target unsuspecting individuals through different mediums.

Voice Phishing (Vishing): With the increase of advanced technologies, vishing or voice phishing is the most popular modality for hackers. Cybercriminals pretend to be the part of organizations such as healthcare providers or insurance companies in order to extort information.

Protecting Yourself from Vishing: Like most other social engineering attacks such as email phishing, vishing also lies solely on deception. Any message that seeks to ask you questions that you feel might compromise your personal details whether its email, telephone call or a chat you should disengage from the conversation immediately.
