UK workers are being targeted with a new email money transfer scam, according to a new police intelligence report. The current threat level has been deemed to be high enough to warrant a warning being issued by Financial Fraud Action UK to alert UK employees to the risk of attack.
Rather than the campaign being sent in mass email spam mailings, individuals are being targeted by criminals using a new spear phishing campaign that attempts to fool users into making a transfer from their personal account in order to secure an important work contract, or help resolve an urgent work issue.
The highly convincing scam involves the sending of emails to individuals in a particular organization that is being targeted. The perpetrators of the campaign have masked the email address of the sender, making it appear as if the email has actually been sent by their boss, a work colleague, or member of the accounts department. In some cases, the emails have actually been sent from a real account.
Email money transfer scam conducted in two separate attacks
Criminals first compromise an email account in the organization under attack by gaining access to an individual’s login credentials using a separate phishing campaign or by hacking passwords. Criminals have been able to gather a large amount of data on individuals via social media networks such as Facebook, Twitter, and LinkedIn. That information is subsequently used to craft convincing email campaigns to fool their targets into revealing sensitive information to gain access to their email accounts.
Those accounts are then used to send email requests to other individuals within the organization asking for a bank transfer to be made. The requests are out of the ordinary but, as explained in the scam emails, the payments are critical to the running of the business. Once a transfer has been made, the money is rapidly withdrawn from the scammer’s account. Victims are left with little recourse to get their money back.
The email money transfer scam has proved to be particularly effective. Employees see that the email has been sent by a manager and out of a sense of duty, or fear of job loss, they respond without first checking the genuineness of the email. Oftentimes, the perpetrators of the crime have sent emails from senior managers and partners’ accounts. An employee lower down the ladder would typically not usually have direct contact with these people, lessening the chance of them contacting that person directly to validate the request. Contact information is often provided in the email that will put the target in direct contact with the scammer, who will then validate the request.
Senior managers and partners are the initial targets in this new email money transfer scam. Criminals attempt to fool them into revealing their login credentials. Employees are the secondary targets who actually arrange the transfers to the fraudsters’ accounts. Both groups of individuals should be warned of the risk, and measures should be implemented to reduce the risk of the phishing campaigns being delivered.
To protect against the first attack made by the perpetrators of this email money transfer scam, it is recommended that companies make the following changes to improve security:
- Issue alerts to their employees, including senior managers, warning of the latest wave of phishing campaigns to put them on high alert.
- Enforce changes to email account passwords, ensuring that only secure passwords are used. Stipulate a minimum of 8 characters, force the use of special characters (!,”,£,$,%,^,&,*,(, or ) for example), and ensure that at least one capital letter and number is included.
- Purchase a robust Anti-Spam filtering solution to prevent phishing emails from being delivered to employee’s inboxes. SpamTitan also includes an Anti-Phishing module that can provide additional protection against complex campaigns such as this.
- Ensure that all Anti-Virus software has virus definitions updated on a daily basis
- Scammers often attempt to obtain login credentials by fooling targets into visiting a link to a malicious website containing malware. The sites may contain malicious code that probes for weaknesses in the target’s browser. The attackers then use SQL injection techniques to exploit software vulnerabilities and install keyloggers to obtain passwords. Anti-Phishing software can block these sites, providing protection even if an email link is clicked.
- Security vulnerability scans should be conducted regularly. Updates may be issued regularly so daily checks should be conducted. A scan may reveal a critical Windows 10 security update is required, or Oracle, Chrome, Firefox, Skype, or Adobe Flash may need to be updated.
- Inform employees of the company’s processes for requesting payments via bank transfers and confirm that under no circumstances would an employee receive a request via email to make a transfer to a senior manager or partner.
Protecting end users from becoming victims of an email money transfer scam
End users should also be informed about the correct actions to take when receiving email requests:
- This email money transfer scam relies on the user being fooled into thinking the email has been sent from a manager’s account. End users should check the email address used to make sure it has been sent from a company account, but to be wary that an email could have been hijacked.
- To contact the person who has made the request directly. Since email accounts may have been compromised, this should be done via telephone using the company switchboard or direct deal numbers, not the telephone numbers supplied in the email.
- To exercise extreme caution when receiving any request which appears to be out of the ordinary, especially when that request involves making a bank transfer or requests that sensitive information is disclosed.
- To read any email carefully, and then re-read it to identify spelling errors, grammatical mistakes or language that would be out of keeping with an email typically sent by that individual.
