Top 9 Types of Cyber ​​Attacks Against Business Users

0

The 21st century is not devoid of crypto ransomware attacks, worldwide distributed cloud-based service shutdowns, and other forms of cyberattacks.

The main underlying problem is that businesses and individuals are equally affected by these attacks. And if you want to protect your business against cyberattacks, you should be aware of some of the most common cyberattacks in the business world.

These nine main types of cyberattacks will give you an idea of ​​what is prevalent in the market and what to look for before opening malicious links or files.


1. Phishing

Social engineering phishing attacks lure you in with fake messages that often convey excessive urgency while urging users to act immediately.

Some common examples of phishing attacks include authentic-looking social media login updates, e-commerce payment updates, payment gateway messages, Microsoft 365 account action messages, and many others.

Verizon’s 2021 Cybersecurity Report confirmed that 96% of phishing attacks occur via email, while 3% occur via (smishing or SMS attacks) and 1% via vishing (phone attacks).

Spear phishing (targeted attacks on business users) and whaling (random hunting victims in a group) have increased during the pandemic.

2. Malware

In 2021, malware caused 61% of business-oriented cyberattacks, as reported by Comparitech.

Suppose you are a business user based in the United States or the United Kingdom. In this case, you need to worry about your cybersecurity and how best to implement strategies to prevent malware-based attacks.

In 2022, malware is sophisticated enough to spread from employee to employee while crippling organizations entirely with data theft and ransomware. Nevertheless, overall malware attacks decreased for the first time since 2016.

Google reports that of 2.195 million compromised websites listed in its 2021 Transparency Report, only 27,000 were the result of malware.

3. DNS Tunneling

DNS tunneling exploits your data network through DNS queries and response packets. DNS tunneling allows the attacker to forward genuine host requests from your server to unscrupulous and unverified channels.

The infiltrators then spread malware from the infected endpoint that bypasses TCP/UDP connections, sends commands and uploads data to the remote command and control center.

Hackers commit DNS tunnel attacks by encoding sensitive data in the hostname label of the DNS query. Subsequently, the server sends the data encoded in the resource record of a DNS response packet.

Cyber ​​attackers embed DNS tunneling scripts on your system via spear-phishing or whaling attacks. Attackers further use DNS query reaction conventions to activate the IP stack.

4. Rootkits

Rootkit attacks are another cyberattack to worry about, especially when it comes to confidential data. According to Help Net Security, data spying continues to be the primary motivating factor in 77% of all rootkit-related crimes.


Hackers primarily engage in cyber espionage and data harvesting to intercept traffic or infect superior systems. Investigative forays into social engineering indicate that independent users, professional or otherwise, account for 56% of attacks.

One in four rootkit attacks targets telecommunications services, creating a large pool of victims. A cybersecurity firm said rootkit attacks mainly target government agencies.

Well-organized APT groups are likely to target specific individual users to infect connected systems rather than for financial gain.

However, government data breaches can have devastating consequences like loss of control over civic infrastructure, power plants, power grids, as has happened recently.

5. Internet of Things (IoT) Attacks

As CompTIA reported, 25% of all enterprise-facing attacks result from IoT-related intent. This technology is essential for maintaining and hosting civic services, utilities, business services, healthcare, retail and many more.

You can depend on it for big data analysis and insights across various departments in business settings. This makes IoT security imperative for every organization undergoing digital transformation.

Vigilance and compliance with safety hygiene are essential for professional users. You can start by investing in trained IT security personnel and good IoT endpoint defense tools.

The integration of IoT with machine learning and AI, big data, telecommunications and other technologies projects that IoT security will become an $18.6 billion market in 2022 .

6. Cross-site scripting

You may find a reason to put cross-site scripting attacks on your watch list. They depend on social engineering attacks to steal data and credentials stored on your system.

Hackers can perform a series of such attacks using cookies, IP details, etc. These fakes (XSRF) are more enhanced as they steal security information, digital access, PII and PHI using GET, POST and other HTTP methods.


XSRF attacks can trick you into compromising entire corporate networks and applications. It can also infect commercial web services, as evidenced by the 2020 TikTok XSRF attack.

XSRF attacks have attacked services like YouTube, ING Direct, and antivirus software developers, like McAfee, in the past.

7.SQL Injection

Your business applications can be threatened by SQL injection attacks. They target your web databases for data theft and remote C&C on your business web operations.

Targeted SQL injection attacks have rocked high-level enterprise data systems in the recent past. They can serve as an entry point for attacks on other databases on the same server.

SQL injections are one of the oldest forms of widespread cyberattacks today. Until 2019, they were the basis of 65% of all cyberattacks, according to an Akamai study.

They specifically target network points with poor authentication/firewall standards, weak credentials, poor web hygiene, lack of user awareness, outdated security software definitions and certificates, and even more.

8. Man-in-the-Middle Attack

Man-in-the-middle attacks exploit digital or software activity to steal data. They can either steal data as silent spies or impersonate you to steal your company’s data.

Small-scale MITM attacks focus more on login data theft, financial data theft, and basic user information theft. You can expect MITM attacks to monitor your company’s web services, BI, and SaaS enterprise-wide.

Man-in-the-middle cyberattacks have seen a massive spike in the past two years. Following the teleworking scenarios, India reported that 52% of businesses faced man-in-the-middle attacks once the pandemic started, according to The Financial Express.

9. Denial of Service Attack (DDoS)

According to Cloudflare’s report, a 29% year-over-year and 175% quarter-over-quarter increase was reported in Level 3 and Level 4 DDoS attacks targeting distributed systems, network and the logistical layers of your business.

DDoS attacks are unsavory favorites on this list. DDoS attackers are shifting to intermittent and short duration attacks, with 98% of Q4 attacks lasting just under an hour.

Your organization should prepare a vigilant endpoint-to-endpoint strategy against such attacks. These can include testing your corporate network defenses before a huge breach.

DDoS attacks choose to block the volume of web traffic or packet rates of businesses to overwhelm their infrastructure and services. It would be better to be wary of the recent adoption of DDoS attacks based on SNMP, MSSQL and UDP.

Top cyberattacks to watch out for

Different cyberattacks can have varying impacts on organizations. However, what is really important to note is the intensity of the attacks, as the duration to stop them will also vary accordingly.

However, cyberattacks of all shapes, forms, and sizes can be extremely damaging to organizations and businesses, making them a top-notch threat for everyone.
