Did you know that over a period of 12 months, nearly one-fifth of Canadian businesses experience some form of cyber attack? Or that the average attack lasts approximately 23 hours and costs $5,600 per minute? Or, even worse, 60% of these businesses become so crippled as a result of a data breach, they’re forced to close their doors as a result?
So, how do you know if your business has fallen victim to a cyber attack? Here’s how to tell:
The Top 5 Signs Your Business Has Been Hacked
1. They’ll Tell You
It’s not unheard of for cybercriminals to simply come straight out and notify you that you’ve been hacked. Generally referred to as ransomware, hackers will steal or prevent you from accessing your data (specific files or your entire system), taking it “ransom” until you pay them a fee to release it. This can come in a variety of forms – everything from pop-ups to locked screens - and even though ransomware attacks can be paralyzing to any organization (especially if you haven’t backed up your data), it is not recommended you pay the ransom.
2. Unusual Emails From Other Employee Accounts
If you receive an unusual email from your employer or a coworker asking you to open a link, download info or send money to a client, don’t open it! Hackers rely on email phishing scams to prey on trusting employees who are less likely to question fraudulent emails coming from people they know - encouraging them to infect their systems and the company network with nasty viruses and other forms of malware.
3. Unusual Amounts of Outbound DNS Traffic
To put it simply, Domain Name System (DNS) is the system that connects domain names (human language) to numbers (machine language) on the internet. For instance, an organization may monitor outbound DNS traffic to external sites such as Facebook, to prevent their employees from spending too much time on social media. A sudden and unusual rise in outbound DNS is a telltale sign you’ve been compromised by an outside, criminal network in which your network may now be communicating.
4. Fantom Computers
If you’ve ever noticed your webcam light flickering on without prompting, or your mouse moving on its own internally, this is a sinister sign that hackers have gained control of your network or machine. Other indicators to watch out for include the appearance of unusually large files as a result of your computer’s microphone activating on its own.
5. Denial of Service (DoS), Re-Directs and Other Weird Activity
- DoS attacks – DoS attacks are the ultimate decoy when it comes to infiltrating your business. Typically, hackers will infiltrate your website, shutting it down for intermittent periods of time while in the meantime, they are breaching your network elsewhere.
- Re-Directs – Should your browser automatically re-direct to somewhere other than what you’ve programmed in your browser settings, this could be a sign of a redirect virus.
- Privileged Account Usage – If you notice unusual network activity on your privileged user accounts (i.e. after working hours or the middle of the night) this is is a sure sign of cybercriminal activity. You may also notice failed login attempts and unusual downloads as well.
The above are just a few of the most common indications your business has been hacked. But the truth is, as cybercrime evolves, so too do cybercriminals in their attempts to penetrate and harm businesses.
