In large companies, as a rule the average employee isn’t often asked for an opinion on their career aspirations, areas of interest, or accomplishments outside their job description. It tends to happen once a year — for the performance review. However, many would like to share their thoughts with management much more often. So, when an invitation to take a self-evaluation lands in the inbox, they jump at the chance without hesitation. And this is what cybercriminals exploit in the latest spear-phishing campaign.
Phishing email with invitation
Seemingly from HR, an email arrives containing an elaborate description of the employee self-evaluation procedure, which “promotes candid dialogue between staff members and their managers/supervisors”. It goes on to say that “you can learn a lot about your strengths and shortcomings … to reflect on your successes, areas for development, and career objectives”. All in all, quite a convincing piece of corporate spiel.
Convincing it may be, but all the same the email does contain a few identifiable red flags regarding phishing. For starters, take a look at the domain name in the sender’s address. That’s right, it doesn’t match the name of the company. Of course, it’s possible that your HR department might be using a contractor unknown to you — but why would “Family Eldercare” be providing such services? Even if you don’t know that this is a non-profit organization that helps families care for elderly relatives, the name should ring an alarm bell.
What’s more, the email says that the survey is “COMPULSORY for EVERYONE”, and must be completed “by End Of Day”. Even if we leave aside the crude and faulty capitalization, the focus on urgency is always a reason to stop and think — and check with the real HR department whether they sent it.
Fake self-evaluation form
Those who miss the flags and click through to the form are faced with a set of questions that may actually have something to do with assessing their performance. But the crux of the phishing operation lies in the last three of those questions — which ask the victim to provide their email address, and enter their password for authentication and then re-enter it for confirmation.
This is actually a smart move on the phishers’ part. Typically, phishing of this type leads straight from the email to a form for entering corporate credentials on a third-party site, which puts many on their guard straight away. Here, however, the request for a password and email address (which commonly doubles up as a username) is disguised as part of the form — and at the very end. By this stage the victim’s vigilance is well and truly lulled.
Also note how the word “password” is written: two letters are replaced with asterisks. This is to bypass automatic filters set to search for “password” as a keyword.
How to stay safe
To stop company employees falling for phishing, keep them informed of all the latest tricks (for example, by forwarding our posts about phishing ploys). If you prefer a more systematic approach, carry out regular trainings and checks, for example with our Kaspersky Automated Security Awareness Platform.
Ideally, employees should never even see most phishing thanks to technical means: install security solutions with anti-phishing technology both at the corporate mail gateway level and on all work devices used for internet access.
