Top 10 Cloud Security Breaches in 2024

Cloud security, often called cloud computing security, is defending infrastructure, applications, and data stored in the cloud from threats and cyberattacks. Although cloud security has the same objectives as traditional cybersecurity, it varies in the aspect that managers must protect assets that are housed inside the infrastructure of third-party service providers.

Organizations use cloud computing to lower computing expenses and quickly deploy new computer resources to serve changing business needs. Enterprises now access stakeholders and customers more swiftly than ever thanks to cloud-based technologies, which offer prospects for quick go-to-market.

This article examines the top 10 Cloud Security Breaches and key lessons we can learn from them.

What are Cloud Security Breaches?

Cloud Security Breaches occur when an unauthorized person has access to private data and sensitive personal information in the cloud. This could happen in a variety of situations, such as:

  • Negligence (such as leaving an account open in a public space, which is more likely due to the cloud’s simplicity for remote access)
  • Application Programming Interfaces (APIs) misuse by hackers
  • Sharing files, passwords, and other security information without restriction (management cannot readily trace the sharing data on a cloud-based platform)
  • Engineers working on the cloud sometimes make mistakes that compromise file security or expose data.

Top 10 Cloud Security Breaches

The following are the top 10 cloud security breaches that are occurring in 2024:

#1 Phishing attacks

The first in cloud security breaches is phishing. Phishing begins with a false email or message to grab someone’s attention. This message appears to come from a reliable source. If duped, they might divulge personal information, frequently on a false website. Additionally, their computer might occasionally download malicious malware.

The attackers may only be interested in using the victim’s credit card or personal information to generate money. Sometimes, they send phishing emails to employees to obtain login credentials or other crucial information. To conduct a sophisticated attack on a particular corporation, they do this. And if the companies do not use a DMARC checker to verify the legitimacy of the email sender, they easy fall victim. Cybercriminals frequently use phishing as a starting point for more dangerous assaults like ransomware and advanced persistent threats (APTs).

#2 Malicious cyber attacks

Nobody wants to think that their employees are out to get them, but it’s a sad reality leading to many cloud security breaches yearly.

Sometimes, a person with privileged system access, such as an IT professional or other system administrator, is the most likely offender. A knowledgeable and malicious administrator can leave a back door unlocked or install malicious software on the network to allow data theft. Some people might even be the ones to install the malware, resulting in millions of dollars in losses.

The best way to prevent these kinds of cloud security breaches is to keep an eye on your staff and look for any signs of unhappiness or discontentment. To prevent any possibility of remote access, cancel all network access and passwords whenever a person departs the firm.

#3 Man-in-the-Middle (MitM) Attacks

In a man-in-the-middle attack, an attacker places oneself between two parties to obtain sensitive information while the parties are unaware of it. The following techniques can be used to carry out these cloud security breaches:

  • Utilizing network infrastructure vulnerabilities.
  • Compromising switches or routers.
  • Use malware to take control of equipment. 

Use secure and encrypted communication routes, such as HTTPS for websites or VPNs for network connections, to defend yourself from MitM attacks. Additionally, routinely updating enterprise software can reduce the danger of MitM attacks.

#4 Social engineering

Hackers utilize social engineering tactics to trick and influence people into disclosing private information or taking security-compromising acts. The main goal of social engineering is to deceive people into:

  • Sharing private information voluntarily.
  • Allowing illegal access to computer systems or data. 

In contrast to other hacking techniques, social engineering focuses on human psychology to take advantage of trust, curiosity, and other human attributes. Social engineering attacks involve physically accessing prohibited areas or information and using technology. Hackers can achieve this by fooling their targets into thinking they are someone they can trust, like a coworker.

Strong security policies, knowledge, and education are required to defend against social engineering threats. You need to be aware of any unexpected demands for sensitive information and be wary of them. 

#5 Insider threats

Insider risks are cloud security breaches brought on by someone with authorized access to a company’s systems, networks, or data, who then abuses that access for bad. These people might be partners in the company, contractors, or former or present workers. 

Data theft, leakage, or system disruption happens from a person abusing their rights, whether on purpose or accidentally. The following are some typical types of insider threats:

  • Theft of data 
  • Sabotage
  • Unauthorized entry 
  • Fraud

Insider threats are dangerous because insiders frequently have access to sensitive information, an organization’s security procedures, and weaknesses. They can thus avoid detection and get around security measures faster than outside intruders. 

#6 Eavesdropping attack

When it comes to cyber security breaches, eavesdropping attacks, also known as sniffing or snooping attacks, are a big problem. Your information, including passwords, credit card numbers, and other sensitive data, is easily stolen through these assaults as it is moved from one device to another.

These attacks are particularly effective because they employ unsecured network communications to access data while it is being delivered or received by its user without triggering any form of alert during transmission.

Here are some ways attackers could target you:

  • A communications link between a sender and a recipient would be tapped to eavesdrop. Radiofrequency transmissions or a wire, such as active or inactive telephone lines, electrical wires, or ungrounded electrical conduits, can be used for this. 
  • When we install bugs on phones to record talks, it’s called a listening post. It uses triggers to track when a phone is picked up to make or receive a call and turns off automatically when the call is over. 

#7 Hijacking accounts

Playing on your employees’ weaknesses is one of the most popular ways to create internal cloud security breaches. Many people are uninformed about the risks posed by internal threats and how hackers conduct their attacks.

For instance, many staff are happy to provide only the necessary details over the phone. Some people who fall for the phishing phone call from a cyber attacker even divulge their credentials. Additionally, they are not able to identify phishing emails, particularly those that contain information on a current project or may allude to specific team members.

Your business is unavoidably at risk if ALL of your employers are unaware of the numerous methods that hackers manipulate and obtain information from within.

An employee account can occasionally be hacked. Once they take that action, there is a greater chance that they will be able to access your company’s secure data. Only the information that each employee account needs to perform their duties should be granted access.

#8 Leaked information

Employees knowingly and unknowingly collect information on their phones, cameras, and USB data drives. 

To mitigate cloud security breaches, every business should utilize software to define its guidelines for what kind of computers can access the network and when certain types of data may be downloaded. It is essential to inform employees of the policies and their justifications.

If not, they’ll figure out how to go around them, ignore them, or misinterpret them completely. In actuality, human error—one of the most frequent causes of an inside threat—was the cause of the most recent breach at Virgin Media.

You might want to think about restricting access to web-based email services like Gmail and data storage services. If staff members have access to private data stored in their internet accounts, a threat to internal security is beyond your control.

Additionally, some companies choose to lock down their networks to prohibit wireless access from anyone other than approved customers using their authorized devices. It might be very challenging to figure out if any Bluetooth data is lost.

#9 Downloading malicious content

Employees use the internet for personal purposes while at work. While they are taking a break from their work, they might check their social media or play a quick game.

Through the same routes, malware and virus risks are there, and staff members frequently unintentionally allow them access to the network.

To ensure your company’s security from cloud security breaches, frequently update and fix your IT systems.

Regular security downloads are insufficient. Regular program updates are required, as is antivirus software layering. Don’t rely solely on one layer of defense.

#10 Insecure applications

It’s likely that although your system is extremely safe, your external programs are making things difficult.

Third-party services might severely hamper internal website security. Before installing any program, make sure your team carefully discusses and evaluates if it is appropriate for your network.

To mitigate cloud security breaches, don’t let your personnel download any program they think would be valuable for your business. Make it a rule that the IT department must first approve all applications before being put into use.
