Security researchers have uncovered a new Stuxnet like malware, named as " Havex ", which was used in a number of previous cyber attacks against organizations in the energy sector. Just like Famous Stuxnet Worm , which was specially designed to sabotage the Iranian nuclear project, the new trojan Havex is also programmed to infect industrial control system softwares of SCADA and ICS systems, with the capability to possibly disable hydroelectric dams, overload nuclear power plants, and even can shut down a country's power grid with a single keystroke. According to security firm F-Secure who first discovered it as Backdoor:W32/Havex.A. , it is a generic remote access Trojan ( RAT ) and has recently been used to carry out industrial espionage against a number of companies in Europe that use or develop industrial applications and machines. SMARTY PANTS, TROJANIZED INSTALLERS To accomplish this, besides traditional infection methods such as exploit kits and spam emails,

Today, the estimated number of known computer threats like viruses, worms, backdoors, exploits, Trojans, spyware, password stealer, and other variants of potentially unwanted software range into millions. It has the capability to create several different forms of itself dynamically in order to thwart antimalware programs. Users of the biggest online artwork community, DevianART with Global Alexa Rank 148, are targeted by the potentially unwanted software programs -- delivered by the advertisements on the website, Stop Malvertising reported on Sunday. A Potentially Unwanted Application (PUA) is a program that may not be intentionally malicious, but can negatively affect the performance and reliability of the system by distributing spyware or adware that can cause undesirable behavior on the computer. Some may simply display annoying advertisements, while others may run background processes that cause your computer to slow down. However, unlike malware, users themselves co

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

We have seen cybercriminals targeting PCs with Ransomware malware that encrypts your files or lock down your computer and ask for a ransom amount to be paid in a specified duration of time to unlock it. To deliver the Ransomware malwares to the mobile devices, cyber criminals have already started creating malicious software programs for android devices. Last month, we reported about a new Police Ransomware malware that locks up the devices until the victims pay a ransom to get the keys to unlock the phone. But, the malware just lock the mobile screen and a loophole in the its implementation allowed users to recover their device and data stored on SDcard. Now, in an effort to overcome this, threat actors have adopted encryption in the development of mobile Ransomware malwares. Recently, the security firm ESET has discovered a new Android ransomware, dubbed as Android/Simplocker.A , that has ability to encrypt the files on the device SD card and then demand a ransom from the victim

Ransomware is one of the most blatant and obvious money making schemes for cybercriminals and it was most likely to be known when last year Cryptolocker ransomware targeted millions of computers worldwide. Recently, security researchers at the Antivirus firm TrendLabs have unearthed another sophisticated variant of the ransomware malware which is employing  Windows PowerShell  in an effort to encrypt files on the victims' computer. The firm detected the variant as TROJ_POSHCODER.A . Windows PowerShell is a task automation and configuration management framework from Microsoft, consisting of a command-line shell and associated scripting language. It provides full access to COM and WMI, enabling administrators to perform administrative tasks on both local and remote Windows systems as well as WS-Management and CIM enabling management of remote Linux systems and network devices. It is believed that cybercriminals have used this feature of Windows just in order to make

If you are dealing in cryptocurrency Bitcoin and have Microsoft's Security Essentials (MSE) installed on your system, then you could be infected by a virus called " DOS/STONED " from the Bitcoin BlockChain.

Well, we all are very conscious, when it comes to the security of our personal information, security of our financial data and security of everything related to us. In the world of Smart devices where our Smartphones knows more than we know ourselves. To keep our device protected from harmful viruses, malware or spyware, we totally depend on various security products such as antivirus, firewall and privacy guard apps, that we typically install from some trusted sources, Google Play Store. Most Antivirus apps are available to download for free, but some of them are paid with extra premium features like advance firewall protection, anti theft, App Locker or Cloud Backup etc. But do you believe that just because you're downloading an application from an official app store and also if its a premium paid version, you're safe from malicious software? Think twice. PAID, BUT FAKE ANTIVIRUS APP In Past, Mobile Security Researchers had spotted numerous fake mobile anti

A year back, Security Researchers from the Antivirus firm Kaspersky found a sophisticated piece of malware which they dubbed as ' MiniDuke ', designed specifically to collect and steal strategic insights and highly protected political information, which is a subject to states' security. Now, once again the MiniDuke virus is spreading in wild via an innocent looking but fake PDF documents related to Ukraine , while the researcher at F-Secure were browsing the set of extracted decoy documents from a large batch of potential MiniDuke Samples. " This is interesting considering the current crisis in the area ," Mikko Hypponen, the CTO of security research firm F-Secure, wrote on Tuesday. The Hacker News reported a year ago about the malicious malware that uses an exploit ( CVE-2013-0640 ) of the famous and actively used Adobe Reader . MiniDuke malware written in assembly language with its tiny file size (20KB), and uses hijacked Twitter accounts for Command &a

Again the sophisticated piece of malware, " njRAT " has come to picture targeting the government agencies and organizations in the Middle East, according to the research carried out by Symantec security researchers. The researchers analyzed 721 samples of malicious code ' njRAT ' and revealed that a large number of about 24,000 infected computers worldwide were targeted by the malware infections with 542 control-and-command (C&C) server domain names. njRAT is not a new piece of malware in the market, it is available since June 2013. Till now its three variants have been released and all of which can be propagated through infected USB keys or networked drives. njRAT is a Remote Access Trojan (RAT) intensive in its data-stealing capabilities. In addition to log keystrokes, the malware is capable to access the victim's camera, steal credentials stored in browsers, upload and download files, perform process and file manipulations, view the victim's desktop.

As we reported earlier, Microsoft will stop supporting the Windows XP operating system after 8th April, apparently 95% of the world's 3 million ATM machines are run on it.  Microsoft's decision to withdraw support for Windows XP  poses critical security threat to the economic infrastructure worldwide. MORE REASONS TO UPGRADE Security researchers at Antivirus firm Symantec claimed that hackers can exploit a weakness in Windows XP based ATMs, that allow them to withdraw cash simply by sending an SMS to compromised ATMs. " What was interesting about this variant of  Ploutus  was that it allowed  cybercriminals  to simply send an SMS to the compromised ATM, then walk up and collect the dispensed cash. It may seem incredible, but this technique is being used in a number of places across the world at this time. " researchers said. HARDWIRED Malware for ATMs According to researchers - In 2013, they detected a malware named Backdoor . Ploutus,  installed on ATMs in Mexico, wh

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: Linux/Ebury –  an OpenSSH backdoor use

The Continuous Growth of spyware, their existence, and the criminals who produce & spread them are increasing tremendously. It's difficult to recognize spyware as it is becoming more complex and sophisticated with time, so is spreading most rapidly as an Internet threat. Recently, The security researchers have unearthed a very complex and sophisticated piece of malware that was designed to steal confidential data and has ability able to capture network traffic. The Researchers at the German security company G Data Software , refer the malware as Uroburos , named after an ancient symbol depicting a serpent or dragon eating its own tail, and in correspondence with a string ( Ur0bUr()sGotyOu# ) lurking deep in the malware's code.  The researchers claimed that the malware may have been active for as long as three years before being discovered and appears to have been created by Russian developers. Uroburos is a rootkit designed to steal data from secure facilit

Do you know, A Computer viruses could go Airborne over WiFi networks? Security researchers at the University of Liverpool  in Britain have demonstrated a WiFi virus that can spread between computer networks just like the ' common cold ' spreads between Humans. They have created a proof-of-concept which can infect the entire wireless network instead of a single computer at a time,  that replaces the firmware of the vulnerable Access Point (AP) with a virus-loaded version, and then propagates itself to the next victim on the WiFi network . The  WiFi  based virus named as ' Chameleon ', that can self-propagate over WiFi networks from access point to access point,  but  doesn't affect the working of the Wireless Access Point. This Virus is able to identify WiFi access points that are not protected by encryption and passwords, according to the research paper . It can badly hit less-protected open access WiFi networks available in coffee shops or airp
