EnigmaSoft Threat Scorecard
EnigmaSoft Threat Scorecards are assessment reports for different malware threats which have been collected and analyzed by our research team. EnigmaSoft Threat Scorecards evaluate and rank threats using several metrics including real-world and potential risk factors, trends, frequency, prevalence, and persistence. EnigmaSoft Threat Scorecards are updated regularly based on our research data and metrics and are useful for a wide range of computer users, from end users seeking solutions to remove malware from their systems to security experts analyzing threats.
EnigmaSoft Threat Scorecards display a variety of useful information, including:
Popularity Rank: The ranking of a particular threat in EnigmaSoft’s Threat Database.
Severity Level: The determined severity level of an object, represented numerically, based on our risk modeling process and research, as explained in our Threat Assessment Criteria.
Infected Computers: The number of confirmed and suspected cases of a particular threat detected on infected computers as reported by SpyHunter.

Trojan.Locky.LB is a Windows-based Trojan horse that quietly infiltrates computers and performs malicious actions in the background without the user's knowledge or consent. Classified as a high-risk threat with a danger level of 8 out of 10, this Trojan is designed to give attackers unauthorized access to an infected system, making it a serious concern for both home users and businesses.

What Trojan.Locky.LB Does
Once Trojan.Locky.LB installs itself on a computer, it runs silently in the background, avoiding detection while it carries out harmful tasks. Like other threats in the Trojan category, it may give remote attackers significant or even complete control over the infected system. This can include the ability to covertly delete files, install additional malware onto the machine, steal sensitive information, change system settings, and monitor the victim's activity. Because the Trojan operates stealthily, many users remain unaware that their computer has been compromised until significant damage has already been done.
How It Usually Gets Onto Computers
Trojan.Locky.LB typically spreads by exploiting system vulnerabilities and security flaws found in outdated software or unpatched operating systems. It is also commonly distributed through software downloads from malicious or compromised websites. Another common infection method involves email attachments sent from untrusted or unknown sources. These attachments may be disguised as harmless files, including executables (.exe), screensavers (.pif), video files (.avi), or even image files (.jpg), tricking users into opening them. Once opened, the malicious code executes and the Trojan installs itself without any visible warning signs.
Risks for the User
The presence of Trojan.Locky.LB on a system poses serious risks. Because it can grant hackers remote access, attackers may use the infection to steal personal or financial information, harvest login credentials, or spy on the user's online activities. The Trojan can also serve as a gateway for additional malware, including ransomware or spyware, to be downloaded and installed on the compromised machine. Deleted files, altered system settings, and degraded system performance are also common consequences. In some cases, infected machines may be enlisted into larger networks controlled by attackers for further malicious purposes.
Signs of Infection
Because Trojans like Locky.LB are designed to operate stealthily, noticeable symptoms can be subtle or absent. However, users should watch for warning signs such as unexplained slowdowns in system performance, unfamiliar processes running in the background, unexpected changes to system or browser settings, programs crashing or behaving erratically, and files going missing or becoming inaccessible. Unusual network activity or unexpected outbound connections can also indicate that a Trojan is communicating with a remote attacker.
How to Stay Protected
To reduce the risk of infection from threats like Trojan.Locky.LB, users should keep their operating system and all installed software fully updated to close known security vulnerabilities. Avoid downloading software from untrusted or unofficial websites, and never open email attachments from unknown or unexpected senders, especially executable files or files with unusual extensions. Maintaining regular backups of important files, using a reputable and up-to-date security solution, and practicing caution when browsing the web are all essential steps toward protecting your system from this and similar Trojan threats.

Similar Families
Similar Families
This section lists other families that share similarities with this family, based on EnigmaSoft’s analysis. Many malware families are created from the same malware toolkits and use the same packing and encryption techniques but uniquely extend functionality. Similar families may also share source code, attributes, icons, subcomponents, compromised and/or invalid digital signatures, and network characteristics. Researchers leverage these similarities to rapidly and effectively triage file samples and extend malware detection rules.- Locky.LC
