Darkhotel APT Malware Targets Global CEOs Using Hotel Internet

November 11, 2014Mohit Kumar
A seven-year-old cyber espionage campaign has targeted senior level executives from large global companies by using a specialized Advanced Persistent Threat (APT) , zero-day exploits, and well-developed keyloggers to extract information from them when they stay in luxury hotels during their business trips. The researchers at Moscow-based security firm Kaspersky Lab dubbed the threat as " DarkHotel APT ," appear to have the ability to know in advance when a targeted executive checks in and checks out of a hotel. The group has been operating in Asia since from 2009 but there have been infections recorded in the United States, South Korea, Singapore, Germany, Ireland and many others, as well. It uses hotel Wi-Fi networks to target elite executives at organisations in manufacturing, defense, investment capital, private equity, automotive and other industries. The group has access to zero day vulnerabilities and exploits, and it used them to infect victims. Threa

Trojan.Stabuniq geographic distribution by unique IP address Security researchers from Symantec have identified a new Trojan that appears to be targeting financial institutions. Dubbed Trojan.Stabuniq , the malware has been collecting information from infected systems potentially for the preparation of a more damaging attack. According to researchers , roughly 40 IP addresses infected with the Stabuniq Trojan, 40% per cent belong to financial institutions who are mostly based in Chicago and New York. The malware appears to be spread by a phishing attack through spam e-mail containing a link to the address of a server hosting a Web exploit toolkit . Such toolkits are commonly used to silently install malware on Web users' computers by exploiting vulnerabilities in outdated browser plug-ins like Flash Player , Adobe Reader , or Java. These attacks can be very simple, such as a written email from a prince in Nigeria asking for bank account information. Once in

Rootkit named as "Necurs" infect 83,427 unique machines during the month of November 2012. It is a multi-purpose rootkits capable of posing a threat to both 32 and 64-bit Windows systems. Distributed via drive-by download on the websites that host the BlackHole exploit kit. Like other rootkits it is able to hide itself from detection and also capable of downloading additional malware from outside. Attackers can maintain remote access to a machine this way in order to monitor activity, send spam or install scareware. Rootkit also stop security applications from functioning and hence no detection. Microsoft list this as  Trojan:Win32/Necurs . Trojan:Win32/Necurs is a family of malware that work together to download additional malware and enable backdoor access and control of your computer. The malware can be installed on its own or alongside rogue security software, such as Rogue:Win32/Winwebsec. The malware downloads itself into the folder " %windi

Malware called 'Eurograbber' steals 36 million Euros

December 07, 2012Mohit Kumar
A new version of the Zeus botnet was used to steal about $47 million from European banking customers in the past year. This Zeus variant Trojan is blamed for attacks that stole more than 36 million Euros ($47 million U.S. dollars) from an estimated 30,000 consumer and corporate accounts at European banks. Dubbed "Eurograbber"  is more than just another banking Trojan. It's an exploitation of fundamental online banking authentication practices that could strike any institution. With the phone number and platform information, the attacker sends a text message to the victim's phone with a link to a site that downloads what it says is "encryption software" for the device. Customers become victims of Eurograbber by clicking on malicious links that may come in phishing-attack emails and then after injecting scripts to browser , the malware intercepts two-step authentication text messages sent to customers' phones. Customers at an estimated 30 banks fell vic

New Mac Malware 'Dockster' Found on Dalai Lama site

A new trojan horse app called Dockster is targeting Mac users by exploiting a known Java vulnerability CVE-2012-0507. The trojan is apparently being delivered through a website (gyalwarinpoche.com) dedicated to the Dalai Lama and once installed can collect user keystrokes and other personal information. Mac in Danger ?  Earlier this spring, a Russian security firm discovered a trojan piece of malware which took advantage of a Java vulnerability on many computers, Macs and PCs alike. This trojan, known as "Flashback," was used to enlist some 600,000 infected computers into a botnet. Malware also provides an interface that allows attackers to download and execute additional malware. Dockster has been found to use the same exploit code as the previous SabPab virus to gain access through a backdoor. Dockster is also said to launch an agent called mac.dockset.deman, which restarts each time a user logs in to their Mac. Dockster is only the latest Mac-based threat to h

Detected a malware that steal image files via FTP … Should we be concerned?

November 09, 2012Anonymous
I have recently found an interesting post of Niranjan Jayanand, a researcher of McAfee and members of Facebook team and customer escalation team. The experts announced that his team has recently detected a Trojan that is able to steal every king of image files form a Windows PC, including a memory dump of the victim machine (.dmp files), and upload them to an FTP server. The activities observed are much suspected, they portend that there is an ongoing attack for cyber espionage or a massive information theft operation by  cyber crime  . This could be just a first stages of the attacks in which information are collected for further and complex initiatives. The stolen image files could be used for blackmailing the victims and demanding a ransom , it's nor first time, let's reminds what happened some months ago when nude pictures of celebrities were stolen. This is not the unique use that I could suppose, images could be also used for other purposes, they could be related to reserved

Russian Web proxy with backdoors, Distributing malware

October 09, 2012Mohit Kumar
Antivirus company Symantec has detected a malicious campaign in which hackers managed to deceive thousands of people allegedly signed by a paid proxy service. They expose that hundreds of thousands of users signing up for a cheap and supposedly legitimate proxy service have ended up downloading malware and being ensnared into a botnet. Three months ago, Symantec researchers started an investigation into a piece of malware called Backdoor.Proxybox that has been known since 2010, but has shown increasing activity recently. " The malware is Backdoor.Proxybox, and our investigation has revealed an entire black hat operation, giving us interesting information on the operation and size of this botnet, and leading us to information that may identify the actual malware author ," Symantec. The service - ProxyBox - supposedly provides access to its entire list of thousands of proxies for only $40 a month, which is obviously too cheap a price for the provider to break eve
