Microsoft may be the most impersonated brand in phishing attacks, but the impersonation of LinkedIn is also common and there has been a massive increase in phishing attacks spoofing the professional networking platform in recent weeks.
LinkedIn is an ideal brand to impersonate in phishing attacks and now is the perfect time to be running phishing campaigns due to the Great Resignation. For those unaware of the term, the Great Resignation is a phenomenon where record numbers of employees quit their jobs. The term was coined in May 2021 by Professor Anthony Klotz of Texas A&M University, who predicted that when the pandemic ends there will be a mass exodus of people leaving their jobs.
While there were mass layoffs as a result of the pandemic, many workers who retained their jobs chose not to leave due to the uncertainty of the job market, but now many workers who are not living from paycheck to paycheck are reconsidering their positions. There has certainly been an upward trend in workers voluntarily leaving their jobs since the start of 2021, indicating the great resignation has begun.
LinkedIn is used by job seekers to identify contacts, network, research companies, and find new employment opportunities. A phishing email that spoofs LinkedIn and indicates a potential employer has been reading a user’s profile, shows a message has been sent through the platform, or advises the user about a new job opportunity is likely to be clicked.
LinkedIn phishing campaigns are helped by the regular email communications from LinkedIn advising users of the platform of the number of searches they appeared in, new messages, and alerts about jobs. That means that users of the platform are used to receiving regular communications from the platform, so if a phishing email is received that looks exactly like a LinkedIn communication, there is likely to be less scrutiny of the email that there would be of an email from a platform that rarely communicates with users via email.
The latest LinkedIn phishing campaign uses HTML templates that include the LinkedIn logo and the color scheme used in official LinkedIn communications. The emails also have the same footer as genuine email communications from the platform, including the correct address and unsubscribe option. The display name is spoofed to make it appear as if the emails are official communications; however, closer inspection will reveal the emails have been sent from webmail addresses.
The phishing emails include subject lines such as “Who’s searching for you online”, “You Have 1 New Message,” and “You appeared in 4 searches this week,” exactly mirroring official LinkedIn emails and they also reference well-known companies such as American Express and Tesla to make it appear that the user is being headhunted by a major corporation. The emails have an HTML button to click that will direct the user to a website where LinkedIn credentials are harvested.
LinkedIn phishing campaigns can be highly effective, but as with all phishing scams, there are ways of blocking the attacks. The first is to ensure that an advanced email security solution is deployed to block the phishing emails at the gateway to prevent them from being delivered to inboxes. SpamTitan Plus uses machine learning techniques and predictive analysis to identify suspicious URLs in emails and provides time-of-click protection. If a link is found to be unsafe, a user will be presented with a block page containing additional information and further options.
SpamTitan Plus has 100% coverage of all current market-leading anti-phishing feeds, a 1.5X increase in unique phishing URL detections, and 1.6X faster phishing detections than the current market leaders, with 10 million net new, previously undiscovered phishing URLs added to the solution every single day.
It is also important to provide security awareness training to the workforce to teach employees how to identify phishing emails and to encourage following email security best practices. TitanHQ has created SafeTitan security awareness training to help train the workforce to be security titans. SafeTitan provides behavior-driven security awareness training tailored for the behaviors of individual employees, includes an extensive library of training courses, videos, and quizzes, and provides real-time intervention training combined with simulated phishing attacks. The solution is proven to reduce employee susceptibility to phishing attacks by up to 92%.
