What is the Blocking (Aleta) ransomware?

Blocking is an updated variant of the Aleta ransomware. This malware is designed to encrypt data and demand payment for the decryption tools. In other words, victims cannot access files affected by Blocking (Aleta) ransomware, and they are asked to pay - to recover access to their data.

During the encryption process, files are appended with the cyber criminals' email address and the ".blocking" extension. For example, a file originally titled something like "1.jpg" would appear as "1.jpg.[avalona.toga@aol.com].blocking" - following encryption.

After this process is complete, ransom notes - "!#_READ_ME_#!.inf" - are dropped into compromised folders. Additionally, this malicious software changes the desktop wallpaper.

What is centralheat[.]net?

Typically, web pages like centralheat[.]net are promoted via questionable advertisements, other untrustworthy websites, potentially unwanted applications (PUAs). In other words, it is very uncommon for pages like centralheat[.]net to be visited by users on purpose.

When visited, they open a couple of other questionable sites or load their content - it depends on the visitor's geolocation. It is worthwhile to mention that PUAs can be designed to collect various data and (or) generate advertisements.

What is Paas?

Ransomware is designed to make files inaccessible by encrypting them. As a rule, malware of this type renames files and generates a ransom note (or multiple ransom notes) as well.

Paas ransomware belongs to the ransomware family called Djvu. It renames encrypted files by appending its extension (".paas") to their filenames.

For example, it renames a file named "1.jpg" to "1.jpg.paas", "2.jpg" to "2.jpg.paas", "sample.jpg" to "sample.jpg.paas", and so forth. Like most ransomware variants, it creates a text file as its ransom note - Paas creates the "_readme.txt" file.

What is premiumbros[.]com?

Similar to thenicenewz.com, leasedtohe.biz, news-central.org, fastcaptcharesolve.com, and countless others, premiumbros[.]com is an untrustworthy webpage. This site is designed to deliver questionable material and/or redirect visitors to rogue/malicious websites.

Visitors rarely enter premiumbros[.]com and pages akin to it - intentionally. Most get redirected to them by intrusive advertisements or installed PUAs (Potentially Unwanted Applications).

Reminews[.]com is an untrustworthy website.It shares many common traits with kokotrokot.com, reatenedb.club, ryknewho.club, and countless others. This page operates by delivering dubious material and/or redirecting visitors to rogue/malicious sites.

Users typically access such websites inadvertently; most get redirected to them by intrusive ads or installed PUAs (Potentially Unwanted Applications). These apps do not need explicit permission to infiltrate systems; hence, users may be unaware of their presence.

PUAs are designed to cause redirects, deliver intrusive advert campaigns, and collect browsing-related information.

What is Werise Tweaker?

Werise Tweaker is the name of legitimate software that is designed to optimize and speed up computers. However, there is advertising-supported software that is designed to look like the Werise Tweaker (it has the same name and similar user interface). This adware has nothing to do with the actual Werise Tweaker.

Its main purpose is to generate revenue for its developer by displaying advertisements. Users who have the fake Werise Tweaker installed on the operating system should remove it as soon as possible.

What is the "THUAN HIEP THANH" scam email?

"THUAN HIEP THANH email virus" is a malware-spreading spam campaign. This term defines a mass-scale operation during which deceptive/scam emails are sent by the thousand.

The letters distributed through this campaign - request recipients to review and confirm their purchase order. It must be emphasized that these emails are fake, and when their attachment is opened - it triggers download/installation of the NanoCore RAT (Remote Access Trojan).

Malware within this classification is designed to enable remote access and control over infected devices. These trojans can have a wide variety of heinous functionalities, and they are deemed to be highly dangerous.

What is GeneralObject?

GeneralObject is an adware-type application with browser hijacker traits. It operates by delivering intrusive advertisement campaigns and promoting fake search engines through modifications to browser settings.

Adware and browser hijackers typically spy on users' browsing activity and gather vulnerable data extracted from it. Hence, GeneralObject likely has such data tracking abilities as well.

This app has been observed being distributed via fake Adobe Flash Player updates. It is noteworthy that software products spread using dubious methods are classified as PUAs (Potentially Unwanted Applications).

What is the undwouldm[.]biz site?

Undwouldm[.]biz is a rogue website, which shares common traits with thatthereis.biz, puiont.com, ywfiof.com, and many others. This page is designed to load dubious content and/or redirect visitors to untrustworthy/malicious sites.

What is ZaDaRus?

Most ransomware variants are designed to prevent victims from accessing their files - they encrypt files and demand a payment (typically, in cryptocurrency) in exchange for a decryption software, key. ZaDaRus encrypts files and appends the zadarusfiles@tutanota.com email address, a string of random characters and the ".ZaDaRus" extension.

For example, it renames a file named "1.jpg" to "1.jpg.[ZadarusFiles@tutanota.com][MJ-XH0145796823].ZaDaRus", "2.jpg" to "2.jpg.[ZadarusFiles@tutanota.com][MJ-XH0145796823].ZaDaRus", and so on. ZaDaRus also creates the "Decrypt-me.txt" file (its ransom note) in folders containing affected (encrypted) files.

This ransomware variant is part of the VoidCrypt ransomware family.
