What is Rdtk.io?
Rdtk.io domain is part of a redirect chain. Redirect chain is a sequence of URLs starting from the first – initial URL, ending with the last – final destination URL. For example, www.datalbase.com redirects to Rdtk.io, which in turn redirects to track.aff-flow.com and so on.
Attackers may use long redirect chains to hide malicious content. Most malicious redirects are conditional. It means that redirection only occurs when a certain condition is met. For example, search traffic redirects only occur when someone clicks from Google’s search results.
In some cases, unsuspecting users are taken to a rogue web page containing a pretend CAPTCHA examine, clicking which serves unwanted ads which are disguised to look as if they come from the working system and never from a web browser. In other cases, users are redirected to pages containing malware.

Rdtk.io redirect in detail
Rdtk.io is not the final redirect destination. Depending on the browser and the IP, the visitor gets redirected further. We detected the following domains were used in the redirect chain:
In most cases, malicious redirects occur when users browse high-risk websites, when users click on a malicious link from push notifications and spam emails. In addition, they can be redirected to the first – initial URL by malicious advertisements (malvertising) and Adware. Adware is a type of software that displays advertisements on a user’s device. While many forms of adware are benign and simply show unwanted ads, some forms of adware can also be spyware. Spyware is a type of software that is designed to collect personal information from a user’s device without their knowledge or consent.
Adware can gather data such as user browsing habits, search terms, and sensitive information such as login credentials and financial information. The gathered information is then sent to a third party, who may use it for malicious purposes, such as identity theft or targeted advertising.
Adware can be used by attackers as a means of redirecting users to other websites without their knowledge or consent. This is known as “malicious redirects”. Attackers can use these redirects to carry out various malicious activities, such as phishing, malware delivery, and ad fraud, among others.
In a phishing attack, a user may be redirected to a fake website that appears to be a legitimate site, in order to steal sensitive information such as login credentials or financial information. In a malware delivery attack, the user may be redirected to a website that downloads malware onto their device, compromising their security and privacy. Ad fraud involves redirecting users to websites that artificially inflate ad impressions and generate revenue from advertising.
Below are some examples of malicious sites (phishing, malware delivery, ad fraud, etc):
In summary, malicious redirects can trick users into making security mistakes or giving away sensitive information, exploit vulnerabilities on their computer and install malicious software.

Examples of malicious and scam sites
We have reported several other scam and malicious sites in the past. Examples: Windows Defender Security Center, Your File Is Ready To Download, McAfee TROJAN Virus Detected, You’ve made the 5-billionth search, VPN Update Scam.
Users never visit sites like Rdtk.io themselves. Typically, users are redirected to them after they click on misleading ads, visit torrent, illegal movie streaming and similar websites. Sometimes, users are redirected to the sites due to installed browser hijackers, adware or other unwanted software.
How does Adware get on your computer
A large number of spyware, adware programs, browser toolbars, hijackers, and PUPs are installed when installing freeware and peer-2-peer file sharing software. Therefore, when installing freeware, you need to be careful not to accidentally install additional software. It is important that you pay attention to the EULA (End User License Agreements) and select the Custom, Manual or Advanced setup mode as it will typically disclose what bundled apps will also be installed.
How can you protect against malicious redirects?
There are a number of methods that you can use to protect against malicious redirects and Adware. It is better to use them together, this will provide stronger protection.
- Use an ad blocker. Ad blockers allow you to browse sites without ads, thus eliminating the possibility of clicking on something malicious and preventing it from being downloaded to the machine.
- Pay for premium versions of popular services. The easiest way to avoid adware is to pay for the service you use. Many Internet services make it possible to use them without ads if you purchase a premium subscription. This helps ensure that malicious adware cannot reach you.
- Buy devices from trusted companies with built-in security. There have already been many cases where people who bought inexpensive Android devices found that adware was already installed on their devices. Cheap Android devices do not receive security updates and are therefore particularly susceptible to infection and should be avoided.
- Use an antivirus. Most antivirus programs can block malicious adware. Some malicious adware can block antiviruses, in which case a more aggressive method should be used, which is to use adware removal software. This software can detect and remove adware that has a negative impact on the device.
