Trojan Horse Virus

Trojan Horse Virus is a type of malware that downloads onto a computer disguised as a legitimate program. The delivery method typically sees an attacker use social engineering to hide malicious code within legitimate software to try and gain users' system access with their software.

What Is a Trojan Virus

Trojans are deceptive programs that appear to perform one function, but in fact perform another, malicious function. They might be disguised as free software, videos or music, or seemingly legitimate advertisements. The term “trojan virus” is not technically accurate; according to most definitions, Trojans are not viruses. A virus is a program that spreads by attaching itself to other software, while a trojan spreads by pretending to be useful software or content. Many experts consider spyware programs, which track user activity and send logs or data back to the attacker, as a type of trojan. 

Trojans can act as standalone tools for attackers or can be a platform for other malicious activity. For example, trojan downloaders are used by attackers to deliver future payloads to a victim’s device. Trojan rootkits can be used to establish a persistent presence on a user’s device or a corporate network.

Trojan Infection Methods

Here are common ways trojans can infect computers in your corporate network:

A user is targeted by phishing or other types of social engineering, opens an infected email attachment, or clicks a link to a malicious website

A user visits a malicious website and experiences a drive-by download pretending to be useful software, or is prompted to download a codec to play a video or audio stream

A user visits a legitimate website infected with malicious code (for example, malvertising or cross-site scripting)

A user downloads a program whose publisher is unknown or unauthorized by organizational security policies

Attackers install a trojan by exploiting a software vulnerability, or through unauthorized access.

Daserf” Trojan created by the cyber-espionage group REDBALDKNIGHT is often installed through the use of decoy documents attached in emails.

Types of Trojans

The first trojan seen in the wild was ANIMAL, released in 1975. Since then, many millions of trojan variants have emerged, which may be classified into many types. Here are some of the most common types.

Downloader Trojan

A downloader trojan downloads and deploys other malicious code, such as rootkits, ransomware, or keyloggers. Many types of ransomware distribute themselves via a “dropper”, a downloader trojan that installs on a user’s computer and deploys other malware components. A dropper is often the first stage in a multi-phase trojan attack, followed by the installation of another type of trojan that provides attackers with a persistent foothold in an internal system. For example, a dropper can be used to inject a backdoor trojan into a sensitive server.

Backdoor Trojan

A backdoor trojan opens up a secret communication tunnel, allowing the local malware deployment to communicate with an attacker’s Command & Control center. It may allow hackers to control the device, monitor or steal data, and deploy other software.

Spyware

Spyware is software that observes user activities, collecting sensitive data like account credentials or banking details. They send this data back to the attacker. Spyware is typically disguised as useful software, so it is generally considered a type of trojan.

Rootkit Trojans

Rootkit trojans acquire root-level or administrative access to a machine, and boots together with the operating system, or even before the operating system. This makes them very difficult to detect and remove.

DDoS Attack Trojan (Botnet)

A DDoS trojan turns the victim’s device into a zombie participating in a larger Botnet. The attacker’s objective is to harvest as many machines as possible and use them for malicious purposes without the knowledge of the device owners—typically to flood servers with fake traffic as part of a Distributed Denial of Service (DoS) attack.

Trojan Horse Malware Examples

Zeus

Zeus/Zbot is a malware package operating in a client/server model, with deployed instances calling back home to the Zeus Command & Control (C&C) center. It is estimated to have infected over 3.6 million computers in the USA, including machines owned by NASA, Bank of America, and the US Department of Transportation. Zeus infects Windows computers and sends confidential data from the victim’s computer to the Zeus server. It is particularly effective at stealing credentials, banking details, and other financial information and transmitting them to the attackers. The weak point of the Zeus system is the single C&C server, which was a primary target for law enforcement agencies. Later versions of Zeus added a domain generation algorithm (GDA), which lets Zbots connect to a list of alternative domain names if the Zeus server is not available.

Zeus has many variants, including:

Zeus Gameover—a peer-to-peer version of the Zeus botnet without a centralized C&C.

SpyEye—designed to steal money from online bank accounts.

Ice IX—financial malware that can control content in a browser during a financial transaction, and extract credentials and private data from forms.

Citadel—an open-source variant of Zeus that has been worked on and improved by a community of cybercriminals, and was succeeded by Atmos.

Carberp—is one of the most widely spread financial malware in Russia. Can exploit operating system vulnerabilities to gain root access to target systems. 

Shylock—uses a domain generation algorithm (DGA), used to receive commands from a large number of malicious servers. 

ILOVEYOU

ILOVEYOU (commonly referred to as the “ILOVEYOU virus”) was a trojan released in 2000, which was used in the world’s most damaging cyberattack, which caused $8.7 billion in global losses. The trojan was distributed as a phishing email, with the text “Kindly check the attached love letter coming from me”, with an attachment named “ILOVEYOU” that appeared to be a text file. Recipients who were curious enough to open the attachment became infected, the trojan would overwrite files on the machine and then send itself to their entire contact list. This simple but effective propagation method caused the virus to spread to millions of computers.

Cryptolocker

Cryptolocker is a common form of ransomware. It distributes itself using infected email attachments; a common message contains an infected password-protected ZIP file, with the password contained in the message. When the user opens the ZIP using the password and clicks the attached PDF, the trojan is activated. It searches for files to encrypt on local drives and mapped network drives, and encrypts the files using asymmetric encryption with 1024 or 2048-bit keys. The attackers then demand a ransom to release the files. 

Stuxnet

Stuxnet was a specialized Windows Trojan designed to attack Industrial Control Systems (ICS). It was allegedly used to attack Iran’s nuclear facilities. The virus caused operator monitors to show business as usual, while it changed the speed of Iranian centrifuges, causing them to spin too long and too quickly, and destroying the equipment.

Detect Trojans in Your Organization

Trojans are a major threat to organizational systems and a tool commonly used as part of Advanced Persistent Threats (APT). Security teams can use the following technologies and methods to detect and prevent trojans:

Endpoint protection platforms

Modern endpoint protection systems include device traditional antivirus, next-generation antivirus (NGAV) that can prevent zero-day and unknown trojans, and behavioral analytics that identifies anomalous activity on user devices. This combination of protective measures is effective against most trojans.

Web application firewall (WAF)

A WAF is deployed at the network edge and is able to prevent trojan infections, by preventing downloads of trojan payloads from suspicious sources. In addition, it can detect and block any unusual or suspicious network communication. WAFs can block trojans when they “phone home” to their C&C center, rendering them ineffective, and can help identify the affected systems.

Threat hunting

Threat hunting is the practice of actively searching for threats on corporate networks by skilled security analysts. Analysts use Security Information & Event Management  (SIEM) systems to collect data from hundreds of IT systems and security tools and use advanced searches and data analytics techniques to uncover traces of trojans and other threats present in the local environment.

Triaging user complaints

Often, a simple user complaint about a slow machine or strange user interface behavior could signal a trojan. Triaging IT support requests with behavioral analytics and data from other security tools can help identify hidden trojans.

The following are common symptoms of trojans that may be reported by users:

• *Popups appear, launched by the user’s browser or operating system
• *Disk space disappears, unexplained persistent disk errors
• *Poor system performance, the machine suddenly slows down with no apparent cause
• *The mouse or keyboard operates on their own
• *Computer shuts down or restarts with no user action
• *Change to desktop image or configuration
• *Change to browser homepage or start page
• *Searches redirect to an unknown domain
• *System firewall or antivirus turned off without user intervention
• *Unusual network activity when the user is not active
• *New programs, favorites, or bookmarks not added by the user

Imperva Data Protection Solutions

Imperva helps detect and prevent trojans via user rights management—it monitors data access and activities of privileged users to identify excessive, inappropriate, and unused privileges. It also offers the industry’s leading Web Application Firewall (WAF), which can detect and block trojans when they attempt to contact their Command & Control center. In addition to ransomware detection and prevention, Imperva’s Data Security solution protects your data wherever it lives—on-premises, in the cloud, and in hybrid environments. It also provides security and IT teams with full visibility into how the data is being accessed, used, and moved around the organization.

Marketing

What Is Marketing

Marketing is the process of getting potential clients or customers interested in your

 products and services. The keyword in this definition is "process." Marketing involves researching, promoting, selling, and distributing your products or services. 

This discipline centers on the study of market and consumer behaviors and it analyzes the commercial management of companies in order to attract, acquire, and retain customers by satisfying their wants and needs and instilling brand loyalty.

Definition of Marketing

The definition of marketing is the action or business of promoting and selling products or services, including market research and advertising. Today, marketing is something that every company and organization must implement in its growth strategy. Many companies use marketing techniques to achieve their goals without even realizing it, as they work to promote themselves and increase sales of their product or service. These days, marketing is one of the key aspects of businesses.

People often do not know exactly what marketing is and, when asked, they define it as selling or advertising. While these answers are not wrong, they are only a part of marketing. There are many other aspects to marketing like product distribution, promotion, designing and creating materials like landing pages and social media content, improving customer experience, doing market research, establishing market segments, and much more. Marketing is very broad and encompasses all the strategies that help a company, brand, or individual achieve its objectives. 

• Product. 
• Having a product is key and is the root of all things marketing. A product could be anything that a company offers consumers to satisfy a need. The best thing to do is to decide on your product or service based both on the needs and motivations of consumers and how the product would benefit the consumer, rather than on the object’s physical characteristics or attributes.
• Place. 
• Strategic merchandising locations can be anything from an online store to a channel of physical stores across multiple towns or countries. The goal of the distribution strategy is to enable potential clients to have easy access to your products/services as well as offer a good experience throughout the purchasing process.  
• Price.
• How you price your products and services is an extremely important part of the marketing strategy. This factor affects other factors such as:
• • The margin you hope to obtain.
  • What target market do you want to appeal to and what purchasing power do your consumers have? Do you want to enter the luxury market or the mass market?
  • The company's financial goals.
  • How does the competition price their products and what possible product substitutes are there?
  • Trends and fads.
  • Increasing your price in order to give a better perception of quality.
• Promotion. 
• This refers to all the marketing and communication that is done in order to showcase the benefits of your product or service within the market. This is how you increase sales.

Marketing Do for Your Business

Raising Brand Awareness

This is important because it gets people acquainted with your brand and the products or services you provide. It also makes you memorable to customers who can begin to trust your brand, become loyal clients, and tell their network about you.

 

Generating Traffic

Growing the number of visitors to your site means getting more qualified leads (lead scoring can help determine this) and ultimately increasing your sales. An effective marketing strategy will help you through this process.

Silver Sparrow Malware

What is Silver Sparrow malware?

Silver Sparrow is a malicious program targeting Mac OS operating systems. There are two versions of this malware, the key difference being the targeted OS architecture. Silver Sparrow's activity has been observed in the United States, United Kingdom, Canada, France, and Germany.

One variant of Silver Sparrow is designed for Intel x86_64 system architecture, the other for this and M1 ARM64. The latter is relatively new and, as such, is targeted somewhat less. As mentioned, this piece of malicious software is intended to infect systems with other malware, however, at the time of research, it has not been observed injecting compromised devices with any payloads. Therefore, the specific goals of cyber criminals behind Silver Sparrow are unknown. Likewise, it is unclear what potential damage the malware can cause. Additionally, some aspects of Silver Sparrow make its code easily modifiable, which makes it a versatile threat.

Note that this malware uses Amazon AWS - a legitimate service provided by Amazon Inc. - for its malicious purposes. This increases Silver Sparrow's chances of proliferation, as Amazon AWS offers suitable conditions (e.g., resilient file distribution and content delivery, etc.).Malware capable of causing chain infections (i.e., backdoor functionalities) can infect devices with a wide variety of malicious programs. Furthermore, malware can have varied capabilities in different combinations. For example, Trojans can function as backdoors, allow remote access and control over the infected machine, download content stored on the system, extract content/information from browsers and other installed applications, spy on users (e.g., monitor keystrokes, record/live-stream video and audio, take screenshots, etc.), and so on.

Ransomware operates by encrypting stored data and/or locking the device's screen for ransom purposes. Crytominers use system resources (potentially to the point of system failure) to mine cryptocurrency. To summarize, Silver Sparrow can cause multiple system infections and lead to severe privacy issues, data loss, device damage, financial losses, and identity theft. If it is suspected/known that Silver Sparrow (or other malware) has already infected the system, use anti-virus software to remove it immediately.

the Electorate, OSAMiner, Eleanor, and XCSSET are some examples of other Mac malware. This malicious software can have an array of dangerous functionality, which can pose a correspondingly broad range of serious problems. The sole purpose of this software is to generate profit at users' expense. Regardless of how the malware operates, it is highly dangerous. To ensure device integrity and user safety, it is crucial to eliminate all threats immediately upon detection.

How did Silver Sparrow infiltrate my computer?

The exact method used to spread Silver Sparrow is unknown. Typically, malicious programs are proliferated through untrustworthy download channels (e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third-party downloaders), and illegal activation tools ("cracks"), fake updaters, and spam campaigns. Malware (including ransomware) is usually distributed via malspam campaigns, unofficial software activation ('cracking') tools, Trojans, dubious file/software download sources, and fake software updating tools.

When cyber criminals attempt to distribute malware via malspam campaigns, they send emails that contain malicious attachments or download links for malicious files. Typically, they disguise their emails as official and important. If recipients open the attached file (or a file downloaded via a website link), they cause the installation of malicious software. Cybercriminals commonly attach executable files (.exe), archive files such as RAR, ZIP, PDF documents, JavaScript files, and Microsoft Office documents to their emails. Software 'cracking' tools supposedly activate licensed software illegally (bypass activation), however, they often install malicious programs and do not activate any legitimately installed software. Trojans are other rogue programs that can cause chain infections. I.e., when a Trojan is installed on the operating system, it can install additional malware. Free file hosting websites, freeware download websites, Peer-to-Peer networks (e.g., torrent clients, eMule), unofficial websites, and third-party downloaders are examples of other sources that are used to distribute malware. Cybercriminals disguise malicious files as legitimate and regular. When users download and open them, they inadvertently infect their computers with malware. Fake software updating tools install malicious software rather than updates/fixes for installed programs, or they exploit bugs/flaws of outdated software that is installed on the operating system.

How to avoid installation of malware

Do not trust irrelevant emails that have files attached (or contain website links) and are received from unknown, suspicious addresses. Software should not be downloaded or installed through third-party downloaders, installers, unofficial pages, or other similar sources/tools. Use only official websites and direct links. Installed software should never be updated or activated with third-party, unofficial tools since they can install malware. Furthermore, it is illegal to use third-party tools to activate licensed software. The only legitimate way to update and activate the software is to use tools and functions that are provided by the official developers. Regularly scan your computer with reputable antivirus or anti-spyware software and keep this software up to date.

If your computer is already infected with malware, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them. Screenshot of VirusTotal detections of the installer distributing the second version of Silver Sparrow malware.

Update 2 March 2021 - It is likely that Silver Sparrow infects computers via adware or advertisements, and third-party offers during the installation processes of certain programs. It is known that the purpose of Silver Sparrow is to infect computers with additional malware, but the payload is still unknown whatever it is, it cannot be configured because the configuration file is hosted in AWS S3. Note also that Silver Sparrow uninstalls itself once the "~/Library/._insu" file appears in the system. It is likely that this file is generated when there is nothing more to gain from the infected machine.
