The 7 Most Common Cybersecurity Threats
Businesses around the world are constantly challenged by Cybersecurity threats driven by different attacker groups. The complexity of current information technologies and the way that information is being shared and accessed at work require us to take every action possible to protect this information and keep it safe online. Cybersecurity technologies and controls have matured over time to support our defense practices. Still, security awareness continues to be the most essential line of defense. Due to COVID-19 and rapidly increasing remote work policies, the working environment is no longer restricted to the confines of a secure office. Building users’ security awareness is more crucial now than ever before.
Although attackers invent and use different methods in their attacks, the following list summarizes the most predominant cybersecurity threats everyone should be aware of:
- Password Attacks
- Rogue Software
- Man in the Middle
Phishing is a social engineering attack where the attacker tricks the unsuspecting victim to provide sensitive information or open a malicious file using a fraudulent message that contains a malicious link or harmful attachment. Phishing emails are the most successful and prevalently used form of phishing attacks. Most malware, especially ransomware, delivery starts with phishing emails.
Through Distributed Denial of Service attacks, adversaries can target online services and networks by sending huge volumes of requests and data over the network. When targeted networks get saturated and servers are overloaded, the attacked services will significantly slow down or stop serving legitimate users. Botnets are commonly deployed to perform DDoS attacks.
3. Password Attacks
A password attack is a type of cyber attack where an attacker attempts to continuously guess, or crack the victim user’s account password.
There are several techniques used for cracking a user’s account password, such as Credential Stuffing, Brute-Force attack, Dictionary attack, Password Spraying, Rainbow Table attack, and Keylogger attack.
4. Rogue Software
Rogue software is a malicious program used to mislead users to fix computer slowness or security issues, most commonly claiming a computer virus exists and should be removed. Victim users will be offered to download and install a malicious program, sometimes for a price, to fix the claimed problem. In most cases, the installed program contains malware causing further harm to victim users.
When most people think of cyber attacks, the first thing that comes to mind is malware.
Malware is short for malicious software, which includes programs harmful to networks, computers, and other systems. Malware can damage, disable, or invade the victim’s IT resources and infrastructure. Ransomware is a widely used type of malware that leaks users data or encrypt and block access to data until a claimed ransom has been paid. Paying the ransom does not guarantee access to data will be restored.
6. Man in the Middle
Man-in-the-middle attacks involve a third party intercepting and sometimes exploiting communications between two entities that should remain private. Eavesdropping occurs, but information can be changed or misrepresented by the intruder, causing inaccuracy and even security breaches.
A drive-by download refers to the uninformed download of malicious software to the victim device without necessary user interaction. Drive-by download can take place on an attacker-owned websites, on a legitimate website that has been compromised, or through malicious advertisements displayed on otherwise safe websites.
