Key Insight
Cyber criminals are increasingly exploiting trusted platforms like Google OneDrive, Dropbox, and Adobe to conduct sophisticated phishing attacks known as ChainLink phishing. By using these legitimate services as intermediary pages, attackers bypass traditional security defenses, making it harder for both individuals and organizations to detect and prevent these attacks.
Cyber criminals are increasingly exploiting trusted platforms such as Google Drive, Dropbox, and others to carry out sophisticated phishing attacks known as ChainLink phishing. Unlike traditional phishing attacks that rely on obvious malicious links or attachments, this method first directs victims to legitimate services through a link in an email. After interacting with these trusted platforms, victims are then redirected to a phishing page that closely mimics a legitimate login page, such as Microsoft’s, to steal sensitive information. This tactic takes advantage of the trust users have in these platforms, making it much harder to detect.
For example:
- Google Calendar phishing – Attackers are now using Google Calendar to send fake invites that redirect users to fraudulent login pages. By using Google’s trusted platform, they can trick victims into entering sensitive information, such as account credentials, without raising suspicion.
A recent report by Bitdefender reveals that 84% of major cyber attacks now involve the use of legitimate services to bypass security measures. This highlights the growing trend of attackers leveraging trusted services for phishing attacks, with victims unknowingly giving up their sensitive information.
While phishing attacks have been around for years, ChainLink phishing has become especially dangerous because it makes use of trusted infrastructure and platforms. This evolving method of attack continues to deceive users by hiding its malicious intent, emphasizing that “known good” is no longer a trustworthy security signal—it's now being used as a disguise by bad actors.
- Exploitation of trusted platforms – Attackers target platforms that people use daily and trust, like Google Calendar, making it easier for them to deceive victims.
- Lack of awareness and vigilance – Users often overlook the signs of phishing when they receive seemingly legitimate requests or calendar invites, which increases the risk of successful attacks.
- Bypassing traditional defenses – Since these attacks do not rely on malware, traditional defenses like antivirus software are often ineffective, making them harder to detect and prevent.
- Credential theft – When users interact with legitimate platforms, such as Microsoft login pages, they may be redirected to phishing pages where their login credentials are stolen by attackers, granting unauthorized access to sensitive accounts.
- Financial loss – Once attackers gain access to sensitive financial information, it can lead to unauthorized transactions, fraudulent activities, or drained accounts.
- Data breaches – Phishing attacks can expose personal or company data, making it available to cyber criminals for identity theft, fraud, or malicious use.
- Always verify unexpected communications – Employees should not assume that every message or invite they receive is genuine. If the organization has established secure verification methods, they should use those to confirm the sender before taking action, especially when it involves entering sensitive information or clicking links.
- Use official websites or channels – Employees should avoid following links in unsolicited emails or messages. Instead, they should go directly to the website or platform to manage accounts or complete tasks.
- Report suspicious activity immediately – If employees notice anything unusual or suspicious in their communications, they should report it to the IT team or the service provider right away to mitigate potential threats.
- Ensure verification of critical requests and communications – Encourage employees to verify important communications, especially those requesting sensitive data, account changes, or financial transactions, through additional channels. It’s always better to take a moment to confirm before acting.
- Implement Multi-Factor Authentication (MFA) – Ensure MFA is set up for all accounts, particularly those involving sensitive data or systems. This adds an extra layer of protection even if an attacker gains access to a login credential.
- Promote vigilance when interacting with trusted platforms – Remind employees that even trusted services can be exploited by attackers. Educate them on how to spot suspicious activities, such as unexpected login prompts or unusual requests.
- Monitor communications regularly – Set up systems to monitor interactions and identify any suspicious patterns in emails, messages, or invitations, ensuring that any potential threats are addressed promptly before they escalate.
