A new phishing campaign is exploiting the popularity of google Calendar to trick victims into clicking on malicious links. According to cybersecurity researchers at Check Point, this financially-motivated scam has already affected approximately 300 organizations, sending over 4,000 emails in just four weeks.
The attackers cleverly disguise their emails as legitimate Google Calendar invitations, making them appear to be sent from someone the recipient knows. This tactic exploits the widespread use of Google Calendar, which boasts over 500 million users worldwide, increasing the likelihood of individuals falling for the ruse.
The phishing emails typically include a calendar file with a deceptive .ics extension, containing a link that directs the victim to Google forms or Google Drawings. Once clicked, the link leads to another prompt, often disguised as a reCAPTCHA or support button. Check Point researchers warn that clicking this second link is a mistake.
“Spoiler alert: it’s fake.” Clicking the malicious link transports victims to a webpage mimicking a cryptocurrency mining or Bitcoin support site.
Cybercriminals Exploiting Google Calendar to Launch Phishing Attacks
Security researchers at Check point have uncovered a cunning phishing campaign that leverages fake Google Calendar notifications to trick unsuspecting victims into divulging sensitive data and financial details. The attack starts innocently enough: users receive an email appearing to be a legitimate Google Calendar notification. Though, these emails are cleverly disguised and designed to lead victims to a malicious website. “These pages are actually intended to perpetrate financial scams,” Check Point explained in a blog post detailing the campaign. “Once users reach said page, they are asked to complete a fake authentication process, enter personal information, and eventually provide payment details.” The researchers promptly alerted Google to the issue, and while the tech giant provided recommendations, Check Point also offered its own advice for safeguarding against such attacks. They urge users to exercise caution when encountering event invites that include unusual steps or requests, such as completing CAPTCHA puzzles. A fundamental rule of thumb, they emphasize, is to “think before you click.” Hover over any links within the email and manually type the URL into your browser instead of directly clicking on it.This simple step can help prevent you from falling victim to malicious links or attachments, which are often used to steal credentials and gain access to sensitive data. Another crucial security measure is to enable two-factor authentication for your google account, and ideally, for any platform storing sensitive information. This extra layer of security makes it considerably more tough for attackers to compromise your accounts,even if they manage to obtain your password.Phishing and spoofing attacks are on the rise, posing a meaningful threat to individuals and organizations alike. According to a recent report from the FBI, over 298,000 complaints were filed in 2023 alone, resulting in a staggering $18.7 million in financial losses.
The alarming success rate of these social engineering tactics lies in their simplicity and high potential payoff for cybercriminals. By impersonating trusted entities or leveraging deceptive tactics, attackers can trick victims into divulging sensitive information or clicking on malicious links.
While Google Calendar has recently emerged as a tool used by scammers, their methods are constantly evolving. Attackers are opportunistic and will adapt their strategies to target vulnerable individuals wherever they can find them.
“Don’t fall for the bait,” the FBI cautions, emphasizing the importance of vigilance and awareness in today’s digital landscape.
