El malware (del ingl\u00e9s \u201cmalicious software\u201d), tambi\u00e9n llamado badware, c\u00f3digo maligno, software malicioso, software da\u00f1ino o software malintencionado, es un tipo de software que tiene como objetivo infiltrarse o da\u00f1ar una computadora o sistema de informaci\u00f3n sin el consentimiento de su propietario. El t\u00e9rmino malware es muy utilizado por profesionales de la inform\u00e1tica para referirse a una variedad de software hostil, intrusivo o molesto.1 Antes de que el t\u00e9rmino malware fuera acu\u00f1ado por Yisrael Radai en 1990, el software malicioso se agrupaba bajo el t\u00e9rmino \u00abvirus inform\u00e1ticos\u00bb.<\/p>\n
El software se considera malware en funci\u00f3n de los efectos que provoque en un computador. Malware no es lo mismo que software defectuoso; este \u00faltimo contiene bugs peligrosos, pero no de forma intencionada.<\/p>\n
Los resultados provisionales de Symantec publicados en el 2008 sugieren que \u00abel ritmo al que se ponen en circulaci\u00f3n c\u00f3digos maliciosos y otros programas no deseados podr\u00eda haber superado al de las aplicaciones leg\u00edtimas\u00bb. Seg\u00fan un reporte de F-Secure, \u00abSe produjo tanto malware en 2007 como en los 20 a\u00f1os anteriores juntos\u00bb.<\/p>\n
Seg\u00fan Panda Security, durante los 12 meses del 2011 se crearon 73 000 nuevos ejemplares de amenazas inform\u00e1ticas por d\u00eda, 10 000 m\u00e1s de la media registrada en todo el a\u00f1o 2010. De estas, el 73% fueron troyanos y crecieron de forma exponencial los del subtipo downloaders.<\/p>\n
En vistas del m\u00e1s reciente ataque de ransomware, Avast ha compartido la siguiente informaci\u00f3n. Una cosa para notar que es importante: Todo el mundo ha estado culpando \u00abPetya\u00bb ransomware para este ataque. Los investigadores de Avast, sin embargo, han descubierto que se trata de una modificaci\u00f3n de Petya. Es un malware diferente que abus\u00f3 del c\u00f3digo de Petya, lo remend\u00f3 y lo reutiliz\u00f3 para sus propios prop\u00f3sitos de extorsi\u00f3n. Por lo tanto, est\u00e1n llamando a este \u00abransomware basado en Petya\u00bb.<\/p>\n

\nFurther to reports of a massive cyber attack hitting a number of companies in Ukraine, including banks, energy companies and transport services as well as the government, we believe this is another example of the Petya-based ransomware, which was first identified in 2016. A few months ago, we spotted Petya ransomware patched and bundled in a different malware strain called PetrWrap. The attack appears to be spreading with incidents being reported in Russia, India, France, Spain and also the Netherlands, and those behind the attack demanding a $300 ransom to be paid in the cryptocurrency, Bitcoin.<\/p>\n
This modification of Petya seems to be spreading using the EternalBlue vulnerability, which was the same vulnerability used to spread WannaCry. We have seen 12,000 attempts today by malware to exploit EternalBlue, which we detected and blocked. Data from Avast\u2019s Wi-Fi Inspector, which scans networks and can detect if an Avast PC or another PC connected to the same network is running with the EternalBlue vulnerability, shows that 38 million PCs that were scanned last week have not patched their systems and are thus vulnerable. The actual number of vulnerable PCs is probably much higher.<\/p>\n
We strongly recommend Windows users, regardless if consumer or business users to update their systems with any available patches as soon as possible, and ensure their antivirus software is also up to date.<\/p>\n
While we don\u2019t know who is behind this specific cyber attack, we know that one of the perfidious characteristics of Petya ransomware is that its creators offer it on the darknet with an affiliate model which gives distributors a share of up to 85% of the paid ransom amount, while 15% is kept by the malware authors. The malware authors provide the whole infrastructure, C&C servers, and money transfer method. This type of model is called \u201cransomware as a service (RaaS)\u201d, which allows malware authors to win over non-tech savvy customers to distribute their ransomware.<\/p>\n","protected":false},"excerpt":{"rendered":"
