The aim of most hackers is to be discreet, but there’s almost always a tell-tale sign they’re at work. You just have to know what you’re looking for.

Damage limitation is an essential part of cyber-security and, accordingly, the sooner you realize you’ve been hacked, the sooner you can get to work on rectifying the issue. Establishing that you’ve been hacked, however, isn’t always straightforward. Hackers are well known for their stealthy attack strategies, and, in many cases, you’re unlikely to realize that you’ve been hacked. You may, instead, simply think that your network is experiencing technical problems, and that’s why you can’t access your files, or why your PCs performance has ground to a halt. But you also need to consider that you may have been hacked.

How Do You Know You’ve Been Hacked?

There are several clear giveaways that your organization’s digital defenses have been breached, and here are five of the most sure-fire ways to know you’ve been hacked:

  1. Your Files are Encrypted: your day-to-day IT activity will likely center around the regular usage of files e.g. Word documents and Excel spreadsheets. But what happens when you can’t access these? Firstly, your organization’s productivity will plummet and, secondly, it could indicate that you’ve been the victim of ransomware. If your files are encrypted and a message is received demanding a ransom fee to decrypt them, then you’ve been hacked.
  2. Unusual Network Activity: regular traffic patterns should be easily identifiable on your network logs, but anything unusual should be closely scrutinized. Modern hacking methods often find malware communicating with remote locations to transmit information or download further malware. Therefore, any unknown locations that are delivering or receiving data from your organization need to be investigated.
  3. Persistent Pop-Ups: there’s nothing more irritating than a pop-up window when you’re trying to work on something. But when these are regularly popping up, when they shouldn’t be, there’s a good chance you’ve been hacked. Often, these pop-ups will try to convince you to perform an action, such as downloading an anti-malware app due to an infection on your PC. These, of course, are fake and are simply a devious strategy to get you to download further malware on to your PC.
  4. People Ask You If You’ve Been Hacked: one of the most obvious signs that you’ve been hacked is when people start asking you if you’ve been hacked. And this is because malware often hijacks email accounts to help spread spam. As a result, people you know – who are listed in your email address book – will be receiving spam messages direct from your email account. Naturally, these unusual messages will ring alarm bells with the recipients, and they are likely to check in with you to confirm if your email account has been hacked.
  5. Your Credentials are Available Online: hackers like to make money by harvesting valuable login credentials, these can then be sold to other hackers who want to breach security measures and gain quick, unauthorized access to private networks. Thankfully, applications such as Google’s Password Manager can warn you when these credentials turn up in password dumps, this is a good sign to immediately change all your passwords.

New Domen Malware is Highly Advanced and Dangerous

There’s only one thing worse than malware: clever malware. If it’s clever then it will to be difficult to detect and remove. And Domen is exactly that.

You probably haven’t heard of Domen before, but that’s because it’s a brand new toolkit. And it’s a toolkit which is fiendishly clever. What a hacker classes as ‘good’ malware is one that is deceptive and skilled in the art of subterfuge. If it can adapt to different scenarios and conditions that it’s even better. And, again, Domen ticks these boxes.

It certainly doesn’t sound appealing, does it? And I’ll bet my bottom dollar that you don’t want your organization to fall victim to it. Well, to help you avoid the perils of Domen, let’s hold it up to the light and see what we can make of it.

What is Domen?

Social engineering is a key part of the modern hacker’s arsenal, so it’s no surprise to see Domen clutching it so closely to its digital chest. A toolkit, of course, is much more than one single application. As the name suggests, it’s packed full of different applications that can work individually or side by side to maximize its impact. Domen is most likely to be found housed within the code of a compromised website – sites based upon WordPress are particularly affected – where it lurks discreetly and quietly.

However, Domen will not lurk discreetly for long. Nonetheless, when it does make an appearance it takes a keen eye to spot that anything is amiss. The infected website will generate a pop-up window that contains a link to a malicious download. This download will initiate a PowerShell attack that leaves your PC at the mercy of hackers who will gain full control of it. Dangerous pop-up windows are nothing new, but Domen differs in that it’s adaptive to the PC it’s attacking.

Domen has been designed so that it identifies the operating system, the user’s location and their browser. It’s at this point that the social engineering aspect comes into play. Domen uses this unique data to tailor a specific pop-up window that urges the user to download a necessary update. So, for example, if you’re using a Chrome browser then a pop-up will appear for a Chrome update.  And, if you’re based in France, for example, the content will be written in French.

Protecting Your Organization from Domen

It’s important that you practice vigilance when working with PCs as malware is so prevalent in the digital age. Evidence of malware such as Domen being present can include:

  • Your default browser homepage changing to something new without your authorization
  • New software installed and loading at startup
  • Evidence of remote access to your PC taking place

Thankfully, the PowerShell attack – initiated by the download of a .hta file – can be thwarted by protecting yourself with any good cyber-security suite. The tools contained with these suites should be able to identify the malicious .hta file and prevent it from executing on your PC. However, this can all be prevented by being vigilant and ignoring any suspicious pop-ups.
