Significant Attacks on Cloud-based Servers and How to Avoid Them

Cloud computing is reshaping how businesses manage data. The global cloud computing market is estimated to rise to billions of dollars in 2028. Therefore, the hackers couldn’t help but valve their penetrating eyes into this growing lucrative market.

Cloud computing adoption has its own pitfalls. However, the most giant elephant in the room is and will continue to be the security.

Understanding Cloud-based Server Attacks

In this context, cloud attacks are cyber-attacks on services that are based in the cloud. These could be in the form of data storage and processing services or hosted applications under Platform as a Service (PaaS) or Software as a Service (SaaS) environments.

The consequences include data breaches, loss of unauthorized access to crucial information, and disruption of services.

Organizations genuinely need to act correctly in terms of security protocols and also have a ‘beading eye’ on their cloud assets. If you need more proof, you can just look at some of the major data breaches that hit major companies last year and remember why cloud security should be a priority.

2. BlueBleed – Microsoft’s Azure Major Fumble

A misconfigured Azure Blob Storage bucket exposed 2.4TB of Microsoft customers’ data. The ripple effect was felt throughout tens of thousands of companies.

Worse still, the company’s support staff is on record for saying that their role does not involve alerting GDPR regulators about such bungles. The firm also minimized the seriousness of what happened and claimed that much data was a duplicate. However, the company never shared an actual number.

3. Chinese Police Leaks Data

Recently, hackers stole data from a Shanghai police database that stored delicate details of more than one billion Chinese citizens. It was a jolt to the heart of Chinese data integrity. The data was stored with Alibaba Cloud, implying that the management dashboard had probably been compromised.

4. Microsoft Ambushed by Lapsus$ Extortion Group

Lapsus$ hacking group steals 37GB of data from Microsoft’s Azure DevOps server. The data breach had even spilled out Microsoft’s source code for several projects. Microsoft, not blaming itself anymore, identified the compromised employee account as a cause of this breach.

5. Medibank’s Mammoth Data Debacle

Late last year, there was a major data breach at Medibank, one of Australia’s largest health insurers. In what proved to be a mind-blowing breach of the company’s data network hosted in the cloud, over 9 million customers’ data was exposed.

In addition to the names, this breach included the addresses and passport numbers of the customers. This entire data was later thrown onto the dark web and could be accessed by anyone. Medibank is also currently mired in some class-action lawsuits.

6. Pegasus Airlines’ Cloud Security Incident

Pegasus Airlines nears being charged for data loss of 6.5 TB. This breach caused sensitive flight data to be breached, including information about the crew and source codes manifest in a misconfigured AWS S3 bucket.

Pegasus Airlines could have avoided this incident, however; it is only that corporate security very occasionally gets the right priority.

7. Mangatoon’s Data Hack

One Piece lovers have been introduced to Mangatoon which has an affiliation with the loved anime characters. The site lost the personal information of 23 million of its own users in a breach on their unsecured Elasticsearch database just last year, unfortunately.

The privacy of personal information i.e., names, email addresses, and social media tokens was lost. Such security overlooks are classic. That is why the manga was not updated for several days and the fans were left very perplexed.

8. Puma in the Kronos Ransomware Crosshairs

Puma, the sportswear giant was one of those affected indirectly by ransomware attacks on the Kronos, a cloud-based HR management company. This breach compromised data of more than 6,000 Puma employees.

9. Amazon’s Prime Video Blunder

A security lapse occurred last year when a Prime Video database, with approximately 215 million records of viewers’ online viewing habits was exposed. Amazon blamed a misstep in the deployment process for this. There is only one bright side to the story – no payment info was stolen.

10. Civicom’s Cloud Calamity

Unprotected Amazon S3 bucket leaks 8TB in sensitive customer data for market research service Civicom. It comprised of the conversations done in private and personal recordings. Indeed, it is the best example of how not to keep a cloud-based environment secure.

Cloud Computing Attacks to Watch Out for

All of the security issues you’ve read above are just the tip of the iceberg. Cloud computing has seized the world of technology dictating those in need to be careful and ensure tight security measures are taken to protect this precious cloud.

Here’s the rundown of ten cloud computing attacks that warrant your utmost attention:

1. DDoS Attack

A Distributed Denial-of-Service (DDoS) attack is like a heavy shower. It implies an impressive amount of traffic attacking cloud services. This therefore leaves the system requiring assistance in processing valid requests. These can wreak havoc and subsequently result in astronomical financial difficulties and perception tragedy when essential services come under such siege of traffic.

2. Account Hijacking

It involves the usage of a cloud computing account by some unauthorized persons who gain access cunningly. Once inside, they can also maliciously take advantage of vital resources or manipulate crucial information. They may use high-tech approaches to get login details.

3. Compromising a User’s Account

This is when an attacker is able to breach through the account holder, who could be taking their trust for granted or using deceitful means in order to extract login details. It differs from account hijacking as the account holder unknowingly becomes involved in the compromise.

4. Cloud Malware Injection Attacks

This is a technique whereby hackers introduce malware into cloud resources. It is similar to putting poison in a system, rendering essential processes unsustainable and potential destruction of data. This can range from exploiting weaknesses in the cloud infrastructure to using social engineering techniques that mislead users into downloading malicious software.

5. Insider Threats

The certainty of internal threat is a grim reality no matter how strong a fortress is from the outside. In some cases, the misuse of cloud values in clouts might be found among employees and contract workers. The difficulty of detecting such cases stems from the fact that those involved have authorized access, and their motives may be diverse.

6. Side-channel Attacks

It is an example of an attack that uses information leaked during the physical implementation of a system. This may include planting and performing compromising activities on genuine hardware by putting in place a malicious machine from where secret data can be stolen.

7. Cookie Poisoning

In other words, this entails tampering with cookies through the introduction of cloud applications that are infected. As such, it is well-established that cookies operate as preferences and history banks. When corrupt, they are used to hack into cloud applications.

8. Security Misconfiguration

It takes place when there are improper configurations of cloud resources to counter cyber threats. This entails correctly establishing the access controls, system security, and constant upgradation of system patches.

9. Insecure APIs

APIs without strong security can contain loopholes that hackers use to break into their systems or data. These include poorly documented shadow APIs and API parameters that are vulnerable to injection attacks.

10. Cloud Crypto Mining

Cloud crypto mining involves the use of cloud computing resources for crypto mining without authority. Indeed, they usually tap on stolen credentials or malware to exploit cloud resources to mine cryptos.

3. Regular Audits and Vigilant Monitoring

Regular security audits should be done in order to stay on the course regarding the adopted security policy. Use monitoring tools like watchful sentries, spotting, and reacting that are to patrol and respond quickly when any security incident arises.

4. Strict Access Controls

Never waver in the enforcement of access control policies. You need to make sure that people can get only into the information and resources they need for their roles.

5. Multi-factor Authentication (MFA)

Firms should use MFA to require multiple forms of verification. This adds an extra layer of security against unauthorized access.

6. Secure Your APIs Diligently

Provide regular checks on APIs, and execute the documentation, and authorization for API usage together with acts of validating and sanitation mechanisms.

7. Incident Response Strategy

Create an all-inclusive incident response plan. Being proactive and having security breach action plans can control much destruction.

8. Backup Data with a Recovery Plan

Keep data routinely backed up in a secure place. This ensures that your data can be retrieved without any problems when there is a loss or a ransomware attack.

9. Employ Network Security Measures

Protect your network using firewalls, intrusion detection systems, and secure network architectures.

10. Stay Updated with Regular Patches

Keep updating systems and applications with the latest patches of security.

Do I Need a VPN for Cloud Security?

But with locked-down cloud assets, what about your online traffic? It could be that you are taking a sip of coffee and accessing your files on the cloud remotely through public WiFi.
