WebDiscover Browser is an adware threat developed by a Canada-based company named WebDiscover Media. Once installed on a PC, the malicious app makes a series of unwanted changes to all browsers installed on the computer, leading to a deteriorating online surfing experience. WebDiscover replaces the default home pages and search engines of affected Internet browsers with its own WebDiscover Homepage and WebDiscover Search, respectively. Furthermore, the malicious app modifies the “new tab” settings so that the corrupted browsers launch the malware's own search portal page when the user opens a new tab. Chrome users may not even recognize WebDiscover as an unwanted program and think they...

APT Attack Spreads Malware Using Coronavirus Theme screenshot

The APT (Advanced Persistent Threat) group was spotted sending out spear-phishing emails that allegedly have detailed information about COVID-19, a.k.a.

Flip-search.com

Flip-search.com is a fake search engine's address. Usually, such fake engines are promoted by numerous browser-hijacker applications designed to control the user's Web browser and, more specifically, the homepage, new page tab, and the default search engine. These settings will be modified to open the promoted fake search engine, and every time they are opened, it would generate artificial traffic towards the address. Another common functionality observed in browser hijackers is their ability to harvest various system data. In most cases, the collected information includes browser and search history, clicked URLs, geolocation, IP address, and Internet provider, but some applications try to dig far deeper and actually attempt to access credit or debit card details. Flip-search.com is classified as a fake search engine due to its...

Adr Ransomware

The Adr Ransomware behaves as a typical ransomware threat, but, so far, infosec researchers have not placed it as part of any pre-existing malware family, which makes it a unique threat. When the Adr Ransomware infiltrates a computer, it leverages a strong encryption algorithm to encrypt the files stored there. Affected users will realize that they no longer access their personal or business files leading to potentially severe consequences. This particular ransomware threat changes the names of the files it encrypts drastically. In fact, it substitutes them entirely with a random string of characters that also varies in length, followed by '.adr' as a new extension. The Adr Ransomware's ransom note is then dropped in the 'C:\Users\[Username]' folder as a text file named 'DesktopDECRYPT_ME.TXT.' The instructions left by the...

CoderWare Ransomware

The CoderWare Ransomware is a potent malware threat that aims to extort money from its victims after locking up their computer files with uncrackable encryption. So far, CoderWare has not been classified as part of any of the already established ransomware families, and as a result, it can be considered as a unique crypto locker threat. When CoderWare encrypts a file, it appends '.DEMON' as a new extension to the file's original name. The threat then delivers a ransom note with instructions from the hackers both as text files and displayed in a pop-up window. The text files are named 'README.txt' and will be dropped in every folder that contains the encrypted data. The text from the pop-up window and in the text files is identical. According to the note, the cybercriminals responsible for unleashing the CoderWare Ransomware want to be...

Hyperlinksearch.net

Hyperlinksearch.net is a browser hijacker designed to promote the fake search engine Hyperlink Search. To achieve their goal and have a broad reach, threat actors have made this Potentially Unwanted Application (PUA) capable of affecting all popular browsers. Once installed on a device, Hyperlinksearch.net undertakes some crucial modifications in the browser's settings: it changes the homepage, new tab address, and default search engine, replacing them with the fake search URL – hyperlinksearch.net. After infecting a system, Hyperlinksearch.net launches on every browser startup and redirects all the user searches through its own search engine. That generates artificial traffic and advertising revenue for its creators while putting users' online safety at risk. As fake search tools like this one cannot conduct an independent search,...

Tmanger

Tmanger is a Remote Access Trojan (RAT) tool used in attacks carried out by the Advanced Persistent Threat (APT) group known as TA428. The malware threat was first observed when deployed against targets in Japan, but it can easily be transferred to infect entities from Mongolia, the original target of the TA428 group, or Vietnam, a member of the Belt and Road initiative. The name of the threat - Tmanger, may be a mistyped version of Tmanager, a conjecture supported by several mistyped strings found in the underlying code of the trojan. Tmanger is comprised of three different parts, but they all share certain identical behavior and functions. The names of the components are SetUp, MloadDll, and Client. The SetUp file is the first to be executed and its tasked with establishing the persistence mechanism for the threat. Before that,...

FileEngineering Ransomware

Two different versions of FileEngineering Ransomware has been observed to be unleashed in the wild. The two variants operate in a perfectly identical way - they aim to infiltrate users' computer systems, encrypt the files found there with an uncrackable cryptographic algorithm, and then extort their victims in exchange for the potential decryption of the locked data. The main and only differences between the two FileEnginerring Ransomware threats are the specific email address they leave to their victims as communication channels. Files encrypted by either of the two FileEngineering Ransomware variants will have their original names changed drastically. The threats will first append a string representing the unique ID designated to the PC user, followed by an email address that belongs to the hackers, and finally '.encrypted' as a new...

BBtok Trojan

The BBtok Trojan is a new banking malware strain that has been deployed mostly against users in Mexico. The threat leverages a fileless attack approach to compromise users' devices. For its propagation vector, BBtok Trojan uses phishing emails carrying weaponized attachments consisting of a compressed package delivering threatening lnk files. The email is designed to appear as legitimate as possible, and they attempt to trick the recipient into starting the malware-laced lnk files resulting in the execution of a PowerShell script. Before the main BBtok Trojan component is delivered to the device, several setup stages must be cleared. First, when the initial threatening PowerShell script is activated, it downloads and executes a Loader payload written in .Net. The Loader then deploys the persistence mechanism of the threat by...

BlackRota Backdoor

BlackRota is a backdoor threat written in the Go programming language. BlackRota exploits an unauthorized-access vulnerability found in the Docker Remote API. The threat is capable of compromising both 64-bit and 86-bit architectures but works only on Linux systems. A unique feature of BlackRota is the heave-level of obfuscation that has been implemented by the hackers responsible for the threat. It is extremely rare for malware written in Go to feature such intensive obfuscation measures. In fact, the infosec researchers who analyzed BlackRota state that it is the most obfuscated Go malware they have encountered to date. After infiltrating its target, BlackRota establishes what the researchers called a 'geacon.' It represents a beacon through which the malware communicates with its Command-and-Control server to receive commands and...

As mentioned, Enspread.top has no content, however, it shows a series of misleading text messages, attempting to lure users into allowing browser notifications. The alerts that Enspread.top shows are a clickbait tactic that prompts users to click on a given 'Allow' button and subscribe to the scammers' pop-ups.
