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.Zbot is a fairly generic backdoor Trojan infection that is closely linked to Mal/VB-AER and the Zeus Trojan, one of the most infamous malware infections. Since 2007, Trojan.Zbot has made headlines when Trojan.Zbot was used to infiltrate and steal information from the Transportation Department of the United States. Since March of 2009, Trojan.Zbot and the Zeus Trojan became widespread, infecting millions of computer from all around the world. ESG security researchers detected thousands of FTP servers of some of the most popular websites that were infected with the Zeus Trojan and Trojan.Zbot. Malware analysts estimate that the botnets associated with Trojan.Zbot cost billions of dollars every year and that a large percentage of phishing messages on Facebook and in spam emails are sent in order to spread malware associated with Trojan.Zbot. In the fall of 2010, the FBI cracked down on the criminal network thought to be responsible for an attack using Trojan.Zbot and the Zeus Trojan that resulted in the theft of more than seventy million dollars from American banks. About ninety people were arrested in relation to these criminal acts in the United States, the Russian Federation, the United Kingdom and Ukraine. In 2011, PC security researchers are facing a serious challenge since the source code of Zeus Trojan and Trojan.Zbot were leaked to the public, enabling practically anyone to use Trojan.Zbot to perform their own attacks.

Digital Signatures
Digital Signatures
This section lists digital signatures that are attached to samples within this family. When analyzing and verifying digital signatures, it is important to confirm that the signature’s root authority is a well-known and trustworthy entity and that the status of the signature is good. Malware is often signed with non-trustworthy “Self Signed” digital signatures (which can be easily created by a malware author with no verification). Malware may also be signed by legitimate signatures that have an invalid status, and by signatures from questionable root authorities with fake or misleading “Signer” names.| Signer | Root | Status |

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.- Agent.AIBB
