What is remote access trojan?

Remote Access Trojans are programs that provide the capability to allow covert surveillance or the ability to gain unauthorized access to a victim PC. Remote Access Trojans often mimic similar behaviors of keylogger applications by allowing the automated collection of keystrokes, usernames, passwords, screenshots, browser history, emails, chat lots, etc. Remote Access Trojans differ from keyloggers in that they provide the capability for an attacker to gain unauthorized remote access to the victim machine via specially configured communication protocols which are set up upon initial infection of the victim computer. This backdoor into the victim machine can allow an attacker unfettered access, including the ability to monitor user behavior, change computer settings, browse and copy files, utilize the bandwidth (Internet connection) for possible criminal activity, access connected systems, and more.

How can remote access Trojans be installed?

Specially crafted email attachments, web-links, download packages, or .torrent files could be used as a mechanism for installation of the software.

What is botnet in computer?

Botnets are networks of computers infected by a botnet agent that are under hidden control of a third party. They are used to execute various commands ordered by the attacker. Most common uses of botnets are criminal operations that require distributed resources, such as DDoS attacks on selected targets, spam campaigns, and performing click fraud. Often, the botnet agent is ordered to download and install additional payloads or to steal data from the local computer.

How do botnets communicate?

From the moment of infection, botnet agents keep in touch with their remote Command-and-Control server (C&C). The communication can be carried by various means, and cybercriminals keep on inventing in new methods to hide their data transmission channels. There have been some unusual ways via social media like Twitter or reddit to send commands. However, the most common implementation of the C&C is a web-application, contacted by the client via simple HTTP requests.

What is a rogue scanner?

Rogue scanners, also known as fake scanners, fake AV, or rogueware, are pieces of code injected into legitimate sites or housed in fake sites. Their social engineering tactic normally involve displaying fictitious security scan results, threat notices, and other deceptive tactics in an effort to manipulate users into purchasing fake security software or licenses in order to remove potential threats that have supposedly infected their systems. Their warnings were deliberately crafted to closely resemble interfaces of legitimate AV or anti-malware software, further increasing the likelihood that users who see them will fall for the ploy. These malware can target and affect PCs and Mac systems alike. In 2011, known names in the security industry have noted the dramatic decline of rogue scanners, both in detection of new variants and search engine results for their solutions.

What are the different types of POS malware?

POS malware may come in three types: keyloggers, memory dumpers, and network sniffers.

What is POS malware?

Point-of-sale (POS) malware is software specifically created to steal customer data, particularly from electronic payment cards like debit and credit cards and from POS machines in retail stores. It does this by scraping the temporarily unencrypted card data from the POS’s memory (RAM), writing it to a text file, and then either sending it to an off-site server at a later date or retrieving it remotely. It is believed that criminals behind the proliferation of this type of malware are mainly after data they can sell, not for their own personal use. Although deemed as less sophisticated than your average PC banking Trojan, POS malware can still greatly affect not just card users but also merchants that unknowingly use affected terminals, as they may find themselves caught in a legal mess that could damage their reputation.

What is intrusion detection?

Intrusion detection systems are important tools for blocking software intrusion that can evade detection by antivirus software and firewall utilities. The SolarWinds Security Event Manager is a Host-based Intrusion Detection System. However, there is a section of the tool that works as a Network-based Intrusion Detection System. This is the Snort Log Analyzer. You can read more about Snort below, however, you should know here that it is a widely used packet sniffer. By employing Snort as a data collector to feed into the Snort Log Analyzer, you get both real-time and historic data analysis out of the Security Event Manager.

How does Beast RAT work?

The Beast RAT attacks Windows systems from Windows 95 up to Windows 10. This uses the same client-server architecture that Back Orifice pioneered with the server part of the system being the malware that gets installed surreptitiously on the target computer. Once the server element is operational, the hacker can access the victim computer at will through the client program. The client connects to the target computer at port number 6666. The server is also able to open connections back to the client and that uses port number 9999. Beast was written in 2002 and is still widely in use.

Why do companies use RATs?

RATs can also be used to reroute traffic through your company network to mask illegal activities.

Why is a RAT dangerous?

Nevertheless, what really makes a RAT particularly dangerous is the fact that it can imitate trustworthy remote access apps.

Because it’s more advantageous for hackers to keep out of the limelight and avoid being caught. If you’re not taking proper security measures, it’s possible you could have a Remote Access Trojan on your computer for a long period without it being detected.

How does Snort intrusion detection work?

The intrusion detection mode operates by applying threat intelligence policies to the data it collects, and Snort has predefined rules available on their website, where you can also download policies generated by the Snort user community. You can also create your own policies or tweak the ones Snort provides. These include both anomaly- and signature-based policies, making the application’s scope fairly broad and inclusive. Snort’s base policies can flag several potential security threats, including OS fingerprinting, SMB probes, and stealth port scanning.

What is the best way to detect malware?

The best option, especially for larger organizations, is to employ an intrusion detection system, which can be host-based or network-based. Host-based intrusion detection systems (HIDSs), which are installed on a specific device, monitor log files and application data for signs of malicious activity; network-based intrusion detection systems (NIDSs), on the other hand, track network traffic in real time, on the lookout for suspicious behavior. When used together, HIDSs and NIDSs create a security information and event management (SIEM) system. SIEM is an incredibly beneficial part of a strong security regimen and can help to block software intrusions which have slipped past firewalls, antivirus software, and other security countermeasures.

What was the Russian attack on Georgia?

An example of this occurred in 2008, when Russia used a coordinated campaign of physical and cyber warfare to seize territory from the neighboring Republic of Georgia. The Russian government did this using distributed denial-of-service (DDoS) attacks which cut off internet coverage across Georgia, combined with APTs and RATs allowing the government to both collect intelligence about and disrupt Georgian military operations and hardware. News agencies across Georgia were also targeted, many of which had their websites either taken down or radically altered.

How do remote access Trojans evade live data analysis?

One way in which Remote Access Trojans can evade the live data analysis NIDSs provide is by dividing the command messaging sent through the malware across multiple data packets. NIDSs like Zeek, which focus more on application layers, are better able to detect split command messaging by running analyses across multiple data packets. This is one advantage Zeek has over Snort.
