As the name implies, spear phishing attacks are highly targeted scams. They often occur in professional settings, where the scammers go after one “big phish,” such as a ranking employee with access to finances or data. From there, the scammers employ social engineering (aka manipulation) to trick the target into transferring funds to them or giving them access to sensitive company systems. Sometimes, it’s a mix of both.
Some of the most striking examples of spear phishing attacks come from the Shamoon2 attacks seen in Saudi Arabia back in 2016. Successive waves of attacks ultimately infected machines with malware and destroyed systems.
So, how did this specific spear phishing attack work, exactly? Cybercriminals targeted specific organizations in Saudi Arabia with emails that included malicious attachments in them. Then, when victims clicked and opened the attachment, they were infected, valuable company data was taken and systems were quickly wiped.
Spear phishing has been around for quite some time yet remains as effective as ever. Spear phishing’s success is based on familiarity. Usually, cybercriminals pretend to be an organization or individual that you know and include a piece of content—a link, an email attachment, etc.—that they know you’ll want to interact with.
For example, cybercriminals have taken advantage of tragedies in the headlines and used targeted emails claiming to be a charitable organization asking for donations. In the case of Shamoon2, the attackers lured in victims with a tempting email attachment sent from organizations the victims were likely to trust. But instead of giving to their charity of choice, or opening a seemingly harmless workplace attachment, victims then self-infect their systems with malware.
Moreover, we have seen spear phishing attacks take on an entirely new form with the advent of AI deepfakes. Now, instead of reaching out to victims via email, sophisticated scammers create deepfakes that pose as employees on video calls. All in real-time. Such was the case in Hong Kong in February 2024 where a host of deepfakes pressured a company’s finance officer into transferring $25 million to the scammers running the deepfakes.[i]
Moral of the story: spear phishing (and regular phishing) attacks can be tricky. However, fear not, there’s a lot you can do to stay on top of this threat.
For starters:
Go straight to the source.
Spear phishing attacks can be easily deceiving. In fact, cybercriminals have been able to impersonate known, credible charities or an employer’s business partners and customers. So, if you receive an email from an organization asking for donations or a partner asking you to open a file you didn’t request, a good rule of thumb is to go directly to the organization through a communications channel other than email. Go to the company’s site and do more research from there. That way, you can ensure you’re gaining accurate information and can interact with the right people, rather than cyber-attackers.
Always check for legitimacy first. Spear phishing emails rely on you—they want you to click a link, or open an attachment. But before you do anything, you always need to check an email’s content for legitimacy. Hover over a link and see if it’s going to a reliable URL. Or, if you’re unsure about an email’s content or the source it came from, do a quick Google search and look for other instances of this campaign, and what those instances could tell you about the email’s legitimacy.
Fraudsters do their research — keep your guard up.
Fraudsters select their victims carefully in these targeted attacks. They hunt down employees with access to info and funds and then do their research on them. Using public records, data broker sites, “people finder” sites, and info from social media, fraudsters collect intel on their marks. Armed with that, they can pepper their conversations with references that sound more informed, more personal, and thus more convincing. Just because what’s being said feels or sounds somewhat familiar doesn’t always mean it’s coming from a trustworthy source.
Clean up your online presence.
With that, employees can reduce the amount of personal info others can find online. Features like McAfee Personal Data Cleanup can help remove personal info from some of the riskiest data broker sites out there. I also keep tabs on those sites if more personal info appears on them later. Additionally, employees can set their social media profiles to private by limiting access to “friends and family only,” which denies fraudsters another avenue of info gathering. Using our Social Privacy Manager can make that even easier. With just a few clicks, it can adjust more than 100 privacy settings across their social media accounts — making them more private as a result.
