5 Common Cyber Threats to Watch Out For

5 Common Cyber Threats to Watch Out For

Every business today relies on technology and information for every business process. Regardless of industry, tech drives business results. However, this reliance on information technology (IT) has also created new challenges for businesses.

Cybercriminals of every stripe target businesses every day with cyberattacks designed to compromise data, disrupt operations, or steal money. Protecting your business from cyber threats requires a firm understanding of attackers’ motives and the different types of cybersecurity threats that are out there.

What’s a cyber threat? Which cyber threats should you watch out for? How can a cyberattack hurt your business? Most importantly, what can you do to stop cyber threats before they hurt your business?

What Is a Cyber Threat?

A cyber threat is, according to the Computer Security Resource Center (CSRC):

“Any circumstance or event with the potential to adversely impact organizational operations (including mission, functions, image, or reputation), organizational assets, individuals, other organizations, or the Nation through an information system via unauthorized access, destruction, disclosure, modification of information, and/or denial of service.”

Another way to define the term “cyber threat” is that it’s something that can result in the loss or theft of data, disruption of IT operations, or other damage to the organization.

What separates cyber threats from IT risks? Cyber threats could be considered a subset of IT risks, and are mostly concerned with attacks by malicious actors. IT risks can cover things that aren’t active threats but may increase the organization’s vulnerability to cyberattacks or IT failures—like having single points of failure in the network or obsolete security patches for software.

Who Is Behind Cyber Threats?

The culprits behind cyber threats can vary greatly. Different attackers might have motivations and goals—so the nature of the attacks they conduct will change from one attack to the next. Some of the most common motivations behind cyber threats include:

  • Crime for Profit. This is one of the most common reasons behind cyberattacks. Here, cybercriminals try to steal valuable data they can resell, hold the business’ IT assets hostage for a ransom, or try to trick members of the target organization into paying fraudulent bills.
  • To Steal Intellectual Property. Corporate espionage is another common motivation behind cyberattacks. Here, criminals try to steal sensitive data to pass along to another organization. Advanced persistent threats (APTs) and other malware that can discretely collect and transmit data are popular for this purpose.
  • State-Sponsored Espionage. Some cyberattacks are conducted on the behalf of countries. The goal is often to gain intelligence—such as determining how far along specific research projects are or the locations, identities, and activities of specific government agents. These attackers often target companies working with the U.S. Department of Defense (DoD) or other government agencies.
  • Political Statements. Some cyberattacks are carried out to raise awareness for a political cause or to punish an organization for some perceived infraction against that cause. Distributed denial of service (DDoS) attacks are a popular tool for these attackers.
  • Personal Grudges/Dissatisfaction. Sometimes, an attacker has a personal motive for trying to steal from or otherwise harm the company. Many internal threats arise from disgruntled employees with a personal grudge against the organization or another person within it.

5 Common Types of Cybersecurity Threats

Now that we’ve defined what cyber threats are (and who is likely to be behind them), what are some of the specific threats to know? Some of the most common types of cyber threats companies have to deal with include:

1. Distributed Denial of Service Attacks

DDoS attacks are a common type of cyberattack that seeks to disrupt operations—typically by overloading a target’s systems with requests, leveraging flaws in their firewall or load balancer, or targeting vulnerabilities in the software applications used. Regardless of the specific strategy used, a DDoS attack attempts to overwhelm the target system so it can’t process legitimate traffic.

According to Security Magazine, in the second half of 2020, there was “an increase of over 12% in the number of potential DDoS weapons available on the internet, with a total of approximately 12.5 million weapons detected.” So, there’s no shortage of DDoS options available to attackers.

Many of these attacks leverage the use of botnets—networks of malware-compromised IT assets—to increase the scale of the attack while hiding its origin point. These botnets also make it harder to stop a DDoS attack in progress since there is no single IP address to block to stop the attack. Instead, every IP address in the botnet needs to be blocked.

Here, having an artificial intelligence (AI) solution that leverages machine learning to identify DDoS attacks in real time and automatically respond to them (or at least notify the IT security team) can be invaluable for preventing service disruptions.

2. Ransomware

Ransomware is a form of malware that encrypts data on an organization’s network. This renders the data on the network unusable until they can get the encryption key. Shortly after the infection, the victim is given an ultimatum along the lines of “Pay up or lose your data forever.”

According to an article by PenTest Magazine, 51% of surveyed businesses were hit by ransomware in 2020. Additionally, the article noted that for the average small business, the ransom was about $5,900—but the average for all businesses was $178,000.

Countering ransomware starts with prevention. Avoiding downloading suspicious files and links is a good start. However, this isn’t a perfect strategy, as someone in the organization may eventually download the malware eventually.

Another strategy for fighting ransomware is employing remote data backups. With a remote backup of the company’s most important data, the local storage media can be formatted (or replaced). Then, the remote backup of the data can be downloaded.

3. Phishing

Phishing attacks are a bit different from other cyber threats. Instead of being the threat itself, most phishing attacks are more like a delivery method for other cyber threats (usually malware). In a phishing attack, the attacker sends fraudulent messages to people in an organization to try to trick them into taking a specific action—such as:

  • Downloading a malware program;
  • Clicking on a link to a malware-laden website;
  • Approving a fake invoice; or
  • Giving up sensitive information (user logins, financial data, etc.).

Some phishers will spend a lot of time researching their target before writing their fake message. They’ll use this information to create more believable phishing messages where they pose as a higher-up or as a vendor that the recipient is likely to trust (or listen to without question).

The first line of defense against phishing attacks is employee training. It’s important to set guidelines for internal communication for employees to follow to prevent them from falling for a phish.

For example, it can help to set a policy wherein managers, tech support, or others in the organization will never ask an employee for their login details. This way, phishers who ask for logins won’t be able to succeed.

4. Internal Attacks

Unfortunately, not every cyber threat comes from the “outside.” Some threats come from within the organization itself.

These internal threats can arise for a number of reasons. For example, an employee might be terminated and decide that they want to cause as much harm as possible on their way out. Or, an employee might feel that they aren’t appreciated enough and will try to steal from the company to make up the difference. Others may have joined specifically to get internal access to carry out their attack.

Regardless of the reason, internal attacks can be incredibly damaging and difficult to stop since the attacker has legitimate access to (and knowledge of) the organization’s systems.

Some important steps for minimizing the impact of these attacks include:

  • Applying a Policy of Least Privilege. One of the best ways to minimize the damage an internal attacker can do is to limit their access in the first place. A policy of least privilege restricts employee access to only the systems and applications that they need to do their job—nothing more. This way, if an employee attempts to abuse their access, the damage they can do is limited.
  • Removing User Privileges On Termination. Even when an employee is leaving on good terms, it’s important to immediately terminate their access to the company’s systems. This helps reduce the risk of their credentials being misused.
  • Leveraging Defense in Depth Strategies. Internal firewalls that help keep different assets on the network isolated can help slow the spread of an attack from an insider. This delay can mean the difference between being able to detect the attack before the insider can compromise more sensitive systems and facing the worst possible data breach.

5. Advanced Persistent Threats

“Advanced persistent threat” is a catch-all term for a variety of malware that is designed to be difficult to detect while discretely ferrying data from one system to another. This is a premier tool for cybercriminals to steal data without getting caught—at least for long enough to put the stolen data to use.

How big of a threat are APTs? Big enough that companies are spending billions of dollars per year to stop them. According to projections from Statista, by 2025: “the advanced persistent threat protection market will be worth an estimated almost [sic] 12.5 billion U.S. dollars annually.”

One of the better strategies for countering APTs is to have a solid security information and event management (SIEM) system in place. SIEMs can monitor traffic on a network to identify abnormal use patterns that might indicate an APT that is actively trying to ferry data to a cybercriminal.


Potential Impacts of Cyber Threats

So, why is it important to put a stop to cyber threats before they can impact your organization? The primary reason for proactive cyber defense is to avoid the costs that these cyberattacks can incur. These costs include:

Direct Monetary Losses

Dealing with cyber threats after the fact isn’t cheap. For example, as noted by IBM, the average cost of a data breach in the U.S. is about $8.64 million. While this won’t be the cost for every business, it’s still a sobering number that shows just how much damage a single breach can cause.

Loss of Market Share

Some cyber threats can compromise a company’s competitiveness and damage its reputation. This, in turn, can result in a loss of market share.

For example, say a retail store suffers a major data breach from an APT that compromises the credit card data of all the customers who shopped there over a month-long period of time. After such an event, how likely are customers to return to that store? Odds are, not likely.

In real-world examples of such attacks, it isn’t unusual for a store to see a severe drop in profits immediately after the breach is discovered. For example, Reuters reported that Target had a “46 percent drop in net profit in the crucial holiday quarter” following their headline-making 2013 data breach.

A Flood of IP-Violating Knock-Offs

Sometimes, when a company’s intellectual property is stolen, that company may see a sudden flood of knock-off products or services entering the market that uses their stolen IP. In many cases, the knock-offs are coming from overseas competitors who aren’t directly subject to U.S. copyright and trademark law. This can make it difficult to put a stop to the knock-offs.

Worse yet, these fraudulent products and services are often available for a lower cost since the competitor didn’t have to pay for the R&D to create the IP in the first place. This can mean that the knock-offs undercut the legitimate IP holder’s products and services.

Legal Fees and Settlements

If bad security compliance is found to be the cause of a data breach or similar event—or if consumers are negatively impacted by such a breach—the organization may find itself being subjected to fines or even lawsuits.

Legal action will require experienced legal counsel. Unfortunately, this can be prohibitively expensive. According to Legal Match, the average cost of an attorney can range from $150 to $325 per hour (or more for an especially large, high-powered firm). This might not sound expensive, but attorneys may log hundreds of billable hours for a single case.

These are just a few of the potential impacts that can follow from a cybersecurity incident caused by various cyber threats.
