Zeus (malware) "Zbot" redirects here.
For the action figures, see Zbots. Zeus is very difficult to detect even with up-to-date antivirus software as it hides itself using stealth techniques It is considered that this is the primary reason why the Zeus malware has become the largest botnet on the Internet: some 3.6 million PCs are said to be infected in the U.S. alone. Security experts are advising that businesses continue to offer training to users to teach them to not to click on hostile or suspicious links in emails or Web sites, and to keep antivirus protection up to date. Antivirus software does not claim to reliably prevent infection; for example Browser Protection says that it can prevent "some infection attempts". One countermeasure would be to run a hardware-based solution that is a non-writable, read-only file system and web browser, such as a secure hardware browser . Heuristic analysis. This article is about antivirus software.
For the use of heuristics in usability evaluation, see Heuristic evaluation. Heuristic analysis is a method employed by many computer antivirus programs designed to detect previously unknown computer viruses, as well as new variants of viruses already in the "wild". Heuristic analysis is an expert based analysis that determines the susceptibility of a system towards particular threat/risk using various decision rules or weighing methods. MultiCriteria analysis (MCA) is one of the means of weighing. This method differs from statistical analysis, which bases itself on the available data/statistics. How it works Another common method of heuristic analysis is for the anti-virus program to decompile the suspicious program, then analyze the source code contained within. Effectiveness Heuristic analysis is capable of detecting many previously unknown viruses and new variants of current viruses.

The common thread running through the malware trends we’ve seen in recent months is the evolution, maturation and diversification of the attacks and fraud schemes they facilitate.
Malware, once purpose-built, is clearly becoming a flexible platform — in many respects, it is now almost a commodity. Take, for example, the leak of Carberp’s source code in 2013. Carberp joined Zeus as the latest prominent Man-in-the-Browser malware to become “open.” With access to this source code, cyber criminals can quickly implement a wide variety of attacks and fraud schemes aimed at specific targets. Along with the more traditional and pure in-browser attacks, SMS-stealing attacks are becoming common, researcher evasion is quickly emerging as a malware trend and new approaches to account takeover and remote device control are being encountered more and more frequently. How to remove the Superfish malware: What Lenovo doesn’t tell you.
If you have a Lenovo system that includes the Superfish malware, you'll want to remove it.
Blowing away your system and reinstalling Windows is one way to do this, but while it's a relatively straightforward process, it's a time-consuming one. Using Lenovo's own restore image won't work, because that will probably reinstate Superfish anyway. Performing a clean install from Windows media will work, but you'll have to reinstall all your software and restore all your data from backup to do the job fully. An alternative is to remove the malware itself. Lenovo has published instructions, but at the time of writing, they're woefully inadequate. Carberp Family Malware Targeting the Banking Sector -HackSurfer. A challenge incident responders and fraud analysts for firms in the banking and financial services sector (BFSS) will soon be faced with is an increased incidence of customer take-over fraud from a very advanced malware family that was recently released into the wild (Cohen, 2013, July 9).
After the historic ZeuS Trojan was released into the wild more sophisticated programmers transformed this already powerful banking Trojan into the very virulent Citadel Trojan. The Citadel permutation was even more resilient, evasive, and sophisticated than the ZeuS Trojan (ibid. p.1). Many are now expressing concern about an even more notorious Russian Trojan that can easily be modified to target BFSS firms in the U.S. (Krebs, 2013, June 13).
