Ebury | Breaking Cybersecurity News | The Hacker News

A malware botnet called  Ebury  is estimated to have compromised 400,000 Linux servers since 2009, out of which more than 100,000 were still compromised as of late 2023. The findings come from Slovak cybersecurity firm ESET, which characterized it as one of the most advanced server-side malware campaigns for financial gain. "Ebury actors have been pursuing monetization activities [...], including the spread of spam, web traffic redirections, and credential stealing," security researcher Marc-Etienne M.Léveillé  said  in a deep dive analysis. "[The] operators are also involved in cryptocurrency heists by using AitM and credit card stealing via network traffic eavesdropping, commonly known as server-side web skimming." Ebury was first documented over a decade ago as part of a campaign codenamed  Operation Windigo  that targeted Linux servers to deploy the malware, alongside other backdoors and scripts like Cdorked and Calfbot to redirect web traffic and ...

A Russian man accused of infecting tens of thousands of computer servers worldwide to generate millions in illicit profit has finally entered a guilty plea in the United States and is going to face sentencing in August. Maxim Senakh, 41, of Velikii Novgorod, Russia, pleaded guilty in a US federal court on Tuesday for his role in the development and maintenance of the infamous Linux botnet known as Ebury that siphoned millions of dollars from victims worldwide. Senakh, who was detained by Finland in August 2015 and extradition to the US in January 2016, admitted to installing Ebury malware on computer servers worldwide, including thousands in the United States. First spotted in 2011, Ebury is an SSH backdoor Trojan for Linux and Unix-style operating systems, like FreeBSD or Solaris, which infected more than 500,000 computers and 25,000 dedicated servers in a worldwide malware campaign called ' Operation Windigo .' Ebury backdoor gives attackers full shell control of...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

In late 2013, Security Researchers identified thousands of Linux systems around the world infected with the OpenSSH b ackdoor trojan and  credential stealer  named Linux/Ebury ,  that allows  unauthorized access of an affected computer to the remote attackers. Antivirus Firm ESET's Reseacher team has been tracking and  investigating the operation behind Linux/Ebury and today team  uncovers the details [ Report PDF ] of a massive,  sophisticated and organized  malware campaign called ' Operation Windigo ', infected more than 500,000 computers and 25,000 dedicated servers. ' We discovered an infrastructure used for malicious activities that is all hosted on compromised servers. We were also able to find a link between different malware components such as Linux/Cdorked, Perl/Calfbot and Win32/Glupteba.M and realized they are all operated by the same group. '  ESET reported. Malware used in Operation Windigo: Linu...
