What is the ompanied[.]top website?

Ompanied[.]top is a rogue site sharing many similarities with freevideos24h.com, hey-brazil.net, blackflightfind.tw, and thousands of others. This page presents visitors with dubious material and/or redirects them to untrustworthy or malicious websites.

Typically, rogue sites are accessed unintentionally - via redirects caused by intrusive adverts or installed PUAs (Potentially Unwanted Applications).

What is ourdadaikri[.]com?

Ourdadaikri[.]com is one of the many websites designed to promote various potentially malicious pages and display deceptive content. It is strongly recommended not to trust ourdadaikri[.]com and other similar pages (e.g., freevideos24h[.]com, hey-brazil[.]net, ersfeeiling[.]fun).

Usually, users open such pages unintentionally, for example, by clicking untrustworthy advertisements or visiting other dubious websites, or browsers open them when they have some potentially unwanted application (PUA) installed on them.

It is noteworthy that those apps are called potentially unwanted because most of them get downloaded and installed unknowingly.

What is AccessibleSearchEngine?

Usually, browsers are considered hijacked after the installation of a potentially unwanted application (PUA) designed to change their settings. A browser hijacker is a type of PUA that modifies settings to promote a fake search engine (its address).

AccessibleSearchEngine is designed to promote the search.operativeeng.com address. Another issue with most browser hijackers is that they can access browsing-related information.

In some cases, they can access sensitive details. In one way or another, it is strongly recommended not to have any browser hijacker installed on a browser (or the operating system) or use a fake search engine. It is noteworthy that the AccessibleSearchEngine app adds the "Managed by your organization feature" to hijacked Chrome browsers.

What is ersfeeiling[.]fun?

Similar to applydatinghere.com, blackflightfind.tw, ouropiniio.fun, bennyaflickgotit.ga, and thousands of others, ersfeeiling[.]fun is an untrustworthy website. It is designed to deliver questionable material and/or redirect visitors to unreliable and possibly malicious pages.

What is the "System Administrator Quota Update" scam email?

"System Administrator Quota Update" is the name of yet another phishing spam campaign. This term defines a mass-scale operation during which thousands of deceptive emails are sent.

The letters distributed through this campaign - claim that recipients' email inboxes have reached their storage limit and will not be able to receive/send messages. The goal of this spam mail is to promote a phishing website that is disguised as an email account sign-in page.

Sites of this type are designed to record information entered into them; in this case - account log-in credentials (i.e., email addresses and passwords). Hence, by trusting these scam emails, users can have their mail accounts stolen by scammers.

What is Lohodf?

In most cases, ransomware victims cannot access their files because they are encrypted. Also, they are provided with instructions on how to contact the attackers about the decryption and some other details.

It is common that malware of this type both encrypts and renames files (appends its extension to their filenames). Lohodf appends ".8329892832982983982" as the file extension.

For example, it renames a file named "1.jpg" to "1.jpg.8329892832982983982", "2.jpg" to "2.jpg.8329892832982983982", and so on. This ransomware displays a pop-up window and creates the "КАК РАСШИФРОВАТЬ ФАЙЛЫ.txt" text file as its ransom notes.

Lohodf creates this text file in all folders that contain encrypted files. This ransomware variant belongs to the Xorist ransomware family.

What is ExtendedField?

ExtendedField is a piece of rogue software. It is classified as adware and has browser hijacker traits. ExtendedField operates by delivering intrusive advertisement campaigns and modifying browser settings to promote fake search engines.

Since most users download/install ExtendedField unintentionally, it is also categorized as a PUA (Potentially Unwanted Application). Additionally, apps within this category (adware and browser hijackers included) typically collect browsing-related and other sensitive information.

It is noteworthy that ExtendedField has been observed being distributed via fake Adobe Flash Player updates. Illegitimate software updaters/installers are notorious for proliferating PUAs and even malware (e.g., trojans, ransomware, etc.).
