What is Smart Blocker?

Smart Blocker is a rogue browser extension promoted as an ad-blocking tool (adblock). It specifically promises to block adverts on online videos. This piece of software operates by running intrusive advertisement campaigns. In other words, it delivers various misleading, unreliable, and even malicious ads.

Due to this, Smart Blocker is classified as adware. Additionally, this browser extension spies on users' browsing habits and collects sensitive information. Since most users download/install adware-type products unintentionally, they are also categorized as PUAs (Potentially Unwanted Applications).

What is mahaidroagra[.]com?

Similar to enuebenet.biz, yitmethissu.biz, todhamilton.pro, and thousands of others, mahaidroagra[.]com is a rogue site. Visitors to this page are presented with dubious content and/or get redirected to untrustworthy/malicious websites.

Sites of this type are usually accessed unintentionally; most users get redirected to them by intrusive ads or installed PUAs (Potentially Unwanted Applications). These apps do not need explicit user permission to infiltrate systems. PUAs operate by causing redirects, running intrusive advertisement campaigns, and gathering browsing-related information.

What is attohearally[.]biz?

Attohearally[.]biz is an untrustworthy page designed to check visitor's IP address and then open other pages of this kind or load deceptive content. There are many sites like attohearally[.]biz, for example, rlongletterit[.]biz, enuebenet[.]biz, and yitmethissu[.]biz.

Typically, users do not visit them intentionally - these pages get opened through shady advertisements, websites or by installed potentially unwanted applications (PUAs). It is worth mentioning that it is uncommon for PUAs to be downloaded and installed on purpose.

What is pesoaniz[.]com?

Pesoaniz[.]com is a rogue website, which shares many similarities with rlongletterit.biz, enuebenet.biz, witmayhav.fun, and countless others. This site is designed to present visitors with dubious content and/or redirect them to different unreliable and possibly malicious pages.

Users typically enter such webpages unintentionally. Most get redirected to them by intrusive adverts or installed PUAs (Potentially Unwanted Applications). This software can infiltrate systems without user consent and subsequently cause redirects, deliver intrusive advertisement campaigns, and gather browsing-related data.

What is Undelivered Mails scam?

Scammers use email as a tool for various purposes. One of them is to trick recipients into providing personal information. Emails of this type are called phishing emails.

Typically, scammers behind emails of this type pretend to be legitimate companies and try to trick recipients into providing login credentials (for example, usernames, passwords), credit card details (for example, cardholder name, CVV code, expiry date), social security numbers or other sensitive details.

It is common that scammers use deceptive websites to trick users into providing information. For example, they disguise fake login pages as legitimate, official sites. In one way or another, emails (and links in them) of this type should be ignored.

What is the Industria_host ransomware?

Industria_host is a malicious program, which is identical to the ChupaCabra ransomware. This malware operates by encrypting data to demand payment for the decryption. In other words, the Industria_host ransomware locks files (thereby rendering them inaccessible/unusable) and demands victims pay a ransom to recover access to their data.

During the encryption process, compromised files are appended with the ".industria_host" extension. For example, a file initially titled something like "1.jpg" would appear as "1.jpg.industria_host", "2.jpg" as "2.jpg.industria_host", "3.jpg" as "3.jpg.industria_host", etc.

After the completion of this process, ransom notes are created/displayed in a pop-up window and "HowToDecrypt.txt" text file.

What kind of malware is Exx?

Exx is a piece of malicious software categorized as ransomware. Systems infected with this malware have their data encrypted (files rendered inaccessible) and receive ransom demands for the decryption (access recovery).

During the encryption process, affected files are appended with the ".exx" extension. For example, a file originally named something like "1.jpg" would appear as "1.jpg.exx" - following encryption.

After the completion of this process, Exx ransomware displays a pop-up window, which contains a ransom note. Additionally, this malicious program changes the desktop wallpaper to HELP_RESTORE_FILES.bmp" and drops "HELP_RESTORE_FILES.txt" files into compromised folders. The wallpaper and text files contain identical ransom-demanding messages.

What is Plexita?

Plexita is a hijacker because it modifies browser's settings (forces users to use a fake search engine/visit plexita.com) and does not allow users undo the changes that it has made. It is worth mentioning that most browser hijackers collect browsing data. In some cases, they can access sensitive information.

Another detail about apps of this type is that users rarely download and install them on purpose. For this reason, Plexita and other apps of this type are called potentially unwanted applications (PUAs).

What is the rlongletterit[.]biz website?

Rlongletterit[.]biz is a rogue webpage designed to load dubious content and/or redirect visitors to other untrustworthy or possibly malicious sites. The Internet is full of websites of this type; enuebenet.biz, yitmethissu.biz, and witmayhav.fun are just a couple of examples.

Users typically enter such pages unintentionally; most get redirected to them by intrusive adverts or PUAs (Potentially Unwanted Applications) already installed onto their devices. This software can infiltrate systems without user consent. PUAs are designed to force-open websites, run intrusive advertisement campaigns, and gather browsing-related data.

What is CryT0Y?

In most cases, ransomware is designed to encrypt files (prevent victims from accessing their files), change their extensions, and generate a ransom note (or multiple ransom notes). CryT0Y renames encrypted files by appending the ".cryT0y" extension.

For example, it renames a file named "1.jpg" to "1.jpg.cryT0y", "2.jpg" to "2.jpg.cryT0y", and so forth. Also, it changes the desktop wallpaper, displays a pop-up window, and creates the "READ_IT.txt" text file (all of them contain ransom demanding messages).
