Phishing – An inconspicuous enemy
Do you remember the last suspicious email you received? Maybe not, as recent phishing attacks are so cleverly crafted that even the most attentive user can be fooled. SMBs and government agencies are currently the focus of this nasty phishing campaign uncovered by ESET researchers. Users of the Zimbra software in particular are in the spotlight.
What is Zimbra actually?
For those of you who may be frowning, Zimbra Collaboration is a popular collaboration tool primarily preferred by organizations with tight IT budgets. It represents a cost-effective alternative to the likes of Microsoft Outlook or Mozilla Thunderbird.
The attack: A wolf in sheep's clothing
Simple but sophisticated – that’s how you could describe the attackers’ tactics. The method is classic: an attached document in an email that leads the recipient to a phishing page. But there's more to it than that. This email warns you about a supposed update or other “problem”. And how do most of us react to such an email? That's right, they open the attachment.
Once opened, the user is presented with a deceptively real-looking Zimbra login page. If you enter your data here, it will go directly to the attackers. A smart approach, as this method successfully sneaks past the anti-spam guidelines.
How do I recognize the enemy?
You would think that this type of email would be easy to spot. But not always. Grammatical errors, suspicious senders or a surprising sense of urgency can alert us. But be vigilant! Not every suspicious email will contain such obvious clues.
What now?
It is important to always be on guard. And yes, that sounds cliche, but in this case, a little paranoia can actually be useful. Think twice before clicking a link or opening an attachment. And if you're unsure? Then stay away!
Conclusion: The current phishing attack on Zimbra users shows how important it is to always stay up to date and keep your eyes open. Cybercriminals never sleep and are constantly becoming more innovative. And while this campaign may not be the most technically sophisticated, it still has the potential to cause great harm. It is up to us to remain vigilant and protect ourselves from such threats.
