Secondo quanto riporta il The New York Times, il virus, che si diffonde via internet, è in grado di di 'rubare' documenti digitali, inviare spam, e installare programmi per registrare i caratteri digitati sulla tastiera
Un virus informatico di tipo botnet (diffuso via internet) ha infettato i computer di oltre 2.500 aziende in tutto il mondo: è quanto pubblica il quotidiano statunitense The New York Times, citando l’azienda di sicurezza informatica NetWitness.
Il virus è in grado di 'rubare' documenti digitali, inviare spam, e installare programmi per registrare i caratteri digitati sulla tastiera; lo scopo di questa particolare versione del virus sembra essere quello di raccogliere le password per i servizi bancari on-line, social network e caselle di posta elettronica.
Non si tratta dell’episodio più grave della storia recente: il virus Conficker, creato nel 2008, riuscì ad infettare oltre 15 milioni di pc e continua ad essere presente su milioni di sistemi informatici.

NetWitness Discovers Massive ZeuS Compromise - "Kneber Botnet" Targets Corporate Networks and Credentials
HERNDON , VA - February 18, 2010 - NetWitness, the world leader in advanced persistent threat detection and real-time network forensics, announced today that its analysts have discovered a dangerous new ZeuS botnet affecting 75,000 systems in 2,500 organizations around the world. The newly-discovered infestation, dubbed the "Kneber botnet" after the username linking the infected systems worldwide, gathers login credentials to online financial systems, social networking sites and email systems from infested computers and reports the information to miscreants who can use it to break into accounts, steal corporate and government information, and replicate personal, online and financial identities.
NetWitness first discovered the Kneber botnet in January during a routine deployment of the NetWitness advanced monitoring solutions. Deeper investigation revealed an extensive compromise of commercial and government systems that included 68,000 corporate login credentials, access to email systems, online banking sites, Facebook, Yahoo, Hotmail and other social networking credentials, 2,000 SSL certificate files, and dossier-level data sets on individuals including complete dumps of entire identities from victim machines.
Discussing the importance of the Kneber botnet, Amit Yoran, CEO of NetWitness and former Director of the National Cyber Security Division, said, "While Operation Aurora shed light on advanced threats from sponsored adversaries, the number of compromised companies and organizations pales in comparison to this single botnet. These large-scale compromises of enterprise networks have reached epidemic levels. Cyber criminal elements, like the Kneber crew quietly and diligently target and compromise thousands of government and commercial organizations across the globe. Conventional malware protection and signature based intrusion detection systems are by definition inadequate for addressing Kneber or most other advanced threats. Organizations which focus on compliance as the objective of their information security programs and have not kept pace with the rapid advances of the threat environment will not see this Trojan until the damage already has occurred. Systems compromised by this botnet provide the attackers not only user credentials and confidential information, but remote access inside the compromised networks."
"Many security analysts tend to classify ZeuS solely as a Trojan that steals banking information," stated Alex Cox, the Principal Analyst at NetWitness responsible for uncovering the Kneber-bot, "but that viewpoint is naive. When we began to detect the correlation among both the methodology used by the Kneber crew to attack victim machines and the wide variety of data sets harvested, it became clear that security teams must rethink their entire perspective on advanced threats such as ZeuS and consider more diverse mission objectives."
Over half the machines infected with Kneber also were infected with Waledac, a peer to peer botnet. The coexistence of ZeuS and Waledac suggests the goals of resilience and survivability and potential deeper cross-crew collaboration in the criminal underground.
"NetWitness enables the discovery of malicious code like Kneber - before things get critical and valuable data is lost," said Cox. "It is 100% certain that many organizations have no idea they are victimized by these types of problems because they're just not tooled to see them on their networks. The Kneber botnet is just one category of advanced threat that organizations have been facing the past few years that they are still largely ignorant or blind to today."

1 Questa notizia anche se risalente al 2 Marzo 2009 serve per capire il meccanismo d'azione del trojan.
La nascita di questo trojan risale al 2008, nella notizia indicata si parla gia di una nuova versione e che gia lo scorso anno stava facendo ancora più danni. Ulteriormente sottovalutato, ha portato poi a quelli che sono i risultati nella notizia princiaple di oggi.
p.s. è la prima news che posto; ho cercato di attenermi alle regole indicate ma in caso ci sia qualcosa che non va fatemi sapere. Grazie
