What is cyber hijacking?
Cyber hijacking, or computer hijacking, is a type of network security attack in which the attacker takes control of computer systems, software programs and/or network communications. A wide range of cyber attacks rely on hijacking in one form or another, and -- similar to other hijackings, such as an airplane hijacker or criminals seizing control of an armored transport vehicle -- cyber hijacking is often, but not always, highly illegal with severe consequences for both the attacker and the victim.

How does man in the browser work?
This is similar to a man-in-the-middle attack, but the attacker must first infect the victim's computer with a Trojan through some form of trickery or deceit. Once the victim is tricked into installing malware onto the system, the malware waits for the victim to visit a targeted site. The man-in-the-browser malware can invisibly modify transaction information and it can also create additional transactions without the user knowing. Because the requests are initiated from the victim's computer, it is very difficult for the web service to detect that the requests are fake.
What is session hijacking?

What happens if you hijack a cloud account?
Cloud account hijacking at the enterprise level can be particularly devastating, depending on what the attackers do with the information. Company integrity and reputations can be destroyed, and confidential data can be leaked or falsified causing significant cost to businesses or their customers. Legal implications are also possible for companies and organizations in highly regulated industries, such as healthcare, if clients’ or patients’ confidential data is exposed during cloud account hijacking incidents.
How to keep data secure?
There are simple, effective steps businesses and organizations can take to keep their data secure on the cloud. Be sure to: 1 Check with your service provider to make sure they have conducted background checks on employees who have physical access to the servers in their data centers. 2 Have a strong method of authentication for cloud app users. 3 Make sure all of your data is securely backed up in the event that your data is lost in the cloud. 4 Restrict the IP addresses allowed to access cloud applications. Some cloud apps provide tools to specify allowable IP ranges, forcing users to access the application only through corporate networks or VPNs. 5 Require multi-factor authentication. Several tools exist that require users to enter static passwords as well as dynamic one-time passwords, which can be delivered via SMS, hardware tokens, biometrics, or other schemes. 6 Encrypt sensitive data before it goes to the cloud.
What is cloud account hijacking?
Cloud account hijacking is a common tactic in identity theft schemes in which the attacker uses the stolen account information to conduct malicious or unauthorized activity. When cloud account hijacking occurs, an attacker typically uses a compromised email account or other credentials to impersonate the account owner.
Why is cloud computing important?
While cloud computing carries with it a wealth of benefits to organizations, including reduced capital costs and on-demand resources, it also provides cyber criminals with an environment ripe for attack , since huge amounts of data are housed in one place. Because the data is stored and accessed on devices and resources often shared across many different users, the risks presented by cloud account hijacking are plentiful.
How to choose cloud service providers?
One such step is to carefully review potential contracts and compare the cloud security and data-integrity systems of cloud service providers. Companies should also take a data-driven approach when evaluating potential cloud service providers, including considering the number of data loss or interference incidents a cloud service has experienced. You should know how often the cloud service provider experiences downtime and how the service provider monitors and manages vulnerabilities. Companies should choose cloud service providers that allow clients to audit the providers’ performance in these areas.
What is data security?
These types of data security platforms should include cloud security capabilities such as end-to-end encryption, application control, continuous data monitoring, and the ability to control or block risky data activity based on behavioral and contextual factors involving the user, event, and data access type. This data-aware and comprehensive approach enables organizations to effectively manage cloud security risks while capitalizing on the benefits offered by cloud computing.
What is restricted IP address?
Restrict the IP addresses allowed to access cloud applications. Some cloud apps provide tools to specify allowable IP ranges, forcing users to access the application only through corporate networks or VPNs.
What is WannaCry remote desktop?
WannaCry enumerates current remote desktop sessions and tries to execute the malware on each session. [5]
What is RDP session hijacking?
Adversaries may perform RDP session hijacking which involves stealing a legitimate user's remote session. Typically, a user is notified when someone else is trying to steal their session.
Is RDP legitimate?
Use of RDP may be legitimate, depending on the network environment and how it is used. Other factors, such as access patterns and activity that occurs after a remote login, may indicate suspicious or malicious behavior with RDP.
Can adversaries hijack a remote desktop session?
Adversaries may hijack a legitimate user’s remote desktop session to move laterally within an environment. Remote desktop is a common feature in operating systems. It allows a user to log into an interactive session with a system desktop graphical user interface on a remote system. Microsoft refers to its implementation of the Remote Desktop Protocol (RDP) as Remote Desktop Services (RDS). [1]
What is DNS Hijacking?
DNS hijacking is a type of attack that uses intercepted DNS queries to redirect users to malicious sites or pop-ups. Cybercriminals are not the only ones exploiting DNS. Internet Service Providers (ISPs) also hijack your DNS to redirect your traffic to suit their objectives.
Why is DNS poisoning bad?
Because the DNS resolver manages the requests of all devices on your network, a well-planned cache poisoning attack could endanger your entire LAN and those using it. Just one user clicking a malicious link in an email or pop-up could lead to a host of problems.
Why do people use VPNs?
Today, however, their uses and advantages extend far beyond that. Because a VPN creates an encrypted tunnel through which it ferries all your traffic, it bypasses your router’s settings and performs a DNS request using the VPN’s DNS resolvers.
How many types of DNS hijacking attacks are there?
Generally speaking, there are five types of DNS hijacking attacks that you must protect yourself against:
How to check if a website is phishing?
Always check the URL of the site to make sure that it’s the exact site you intended to visit. If any part of the address appears unfamiliar, close the browser immediately and check your DNS settings for vulnerabilities or leaks. Phishing sites usually do not have a valid SSL (secure sockets layer) certificate. Check to make sure that the site you are using has a valid SSL certificate indicated by the lock icon in your browser’s address bar. Never enter private data (i.e. credit card details, personal info) into a web form on a site that does not have have a valid SSL certificate.
What is DNS request?
Whenever you type the name of a site into your browser, your browser sends that name – the Universal Resource Locator (URL) – to the DNS. This is known as a DNS request.
Why do governments use DNS hijacking?
Many governments will also use DNS hijacking for surveillance and censorship, redirecting users away from banned sites and towards government-authorized sites .
