Fundamentals for Shoring Up Phishing Defences from the NCSA

We would like to thank the National Cyber Security Alliance for providing the following valuable information to help protect from phishing threats. 

From ransomware to SolarWinds, the cybersecurity space has been as hectic as it has ever been over the last 12-24 months. However, for all of the emerging threats and news that are cropping up on the horizon, phishing -- one of the oldest pain points in cybersecurity -- is continuing to quietly wreak havoc, and is as big of a threat as it has ever been.

Despite often being overlooked in terms of hype, phishing has been a mainstay in the cybersecurity threat landscape for decades. In fact, 43 percent of cyberattacks in 2020 featured phishing or pre-texting, while 74 percent of US organisations experienced a successful phishing attack last year alone. That means that phishing is one of the most dangerous “action varieties” to an organisation’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 for dealing with phishing threats.

Know the Red Flags

Phishes are masters of making their content and interactions appealing. From content design to language, it can be difficult to discern whether 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, and subject lines that create a sense of urgency are all hallmarks that the content you received could be potentially from phish and indicate that it should be handled with caution.

Verify the Source

Phishing content comes in a variety of ways, however, many phishes will try to impersonate someone you may already know -- such as a colleague, service provider or friend -- as a way to trick you into believing their malicious content is actually trustworthy. Don’t fall for it. If you sense any red flags that something may be out of place or unusual, reach out directly to the individual to confirm whether the content is authentic and safe. If not, break-off communication immediately and flag the incident through the proper channels.

Be Aware of Vishing and Other Phishing Offshoots

As more digital natives have come online and greater awareness has been spread about phishing, bad actors have begun to diversify their phishing efforts beyond traditional email. For example, voice phishing -- or vishing -- has become a primary alternative for bad actors looking to gain sensitive information from unsuspecting individuals. Similar to conventional phishing, vishing is typically executed by individuals posing as a legitimate organisation -- such as a healthcare provider or insurer -- and asking for sensitive information. Simply put, it is imperative that individuals be wary of any sort of communication that asks for personal information whether it be via email, phone or chat -- especially if the communication is unexpected. If anything seems suspicious, again, break-off the interaction immediately and contact the company directly to confirm the veracity of the communications.

Phishing may be “one of the oldest tricks in the book,” but it is still incredibly effective. And although it may be hard to spot when you may be in the midst of a phishing attempt, by exercising caution and deploying these few fundamentals, individuals and organisations more broadly can drastically mitigate the chances of falling victim to a phishing attack.

Stay Protected 

Prevention is always better than cure, and the best defence is to encourage businesses to proactively boost their company’s cyber resilience levels to avoid being hit by ransomware or other compromises in the first place. The fact that a staggering 94% of malware attacks are delivered by email, makes email an extremely important vector for businesses to fortify.  

Being hit by a cyber-attack can cause businesses significant financial losses and a hit to their reputation, especially following a tough pandemic-ridden year which resulted in many businesses struggling to keep the lights on. If you are using Microsoft 365 or G Suite, you should also have third-party solutions in place to mitigate your risk. For example, using a specialist cloud email security solution like MailGuard to complement Microsoft 365. For more information about how MailGuard can help defend your inboxes, contact us here: expert@mailguard.com.au.
