Malware | Breaking Cybersecurity News | The Hacker News

Cyber criminals have exploited the power of two online advertising networks, Google's DoubleClick and popular Zedo advertising agency , to deliver malicious advertisements to millions of internet users that could install malware on a user's computer. A recent report published by the researcher of the security vendor Malwarebytes suggests that the cyber criminals are exploiting a number of websites, including The Times of Israel, The Jerusalem Post and the Last.fm music streaming website, to serve malicious advertisements designed to spread the recently identified Zemot malware . Malvertising is not any new tactic used by cybercriminals, but Jerome Segura, a senior security researcher with Malwarebytes, wrote in a blog post that his company " rarely see attacks on a large scale like this. " "It was active but not too visible for a number of weeks until we started seeing popular sites getting flagged in our honeypots," Segura wrote. "That's

A huge data-stealing cyber espionage campaign that targeted Banks, Corporations and Governments in Germany, Switzerland, and Austria for 12 years, has finally come for probably the longest-lived online malware operation in history. The campaign is dubbed as ' Harkonnen Operation ' and involved more than 800 registered front companies in the UK — all using the same IP address – that helped intruder installs malware on victims' servers and network equipments from different organizations, mainly banks, large corporations and government agencies in Germany, Switzerland and Austria. In total, the cyber criminals made approximately 300 corporations and organisations victims of this well-organised and executed cyber-espionage campaign . CyberTinel , an Israel-based developer of a signature-less endpoint security platform, uncovered this international cyber-espionage campaign hitting Government institutions, Research Laboratories and critical infrastructure facilit

Over the past two years, a shocking  51% of organizations surveyed in a leading industry report have been compromised by a cyberattack.  Yes, over half.  And this, in a world where enterprises deploy  an average of 53 different security solutions  to safeguard their digital domain.  Alarming? Absolutely. A recent survey of CISOs and CIOs, commissioned by Pentera and conducted by Global Surveyz Research, offers a quantifiable glimpse into this evolving battlefield, revealing a stark contrast between the growing risks and the tightening budget constraints under which cybersecurity professionals operate. With this report, Pentera has once again taken a magnifying glass to the state of pentesting to release its annual report about today's pentesting practices. Engaging with 450 security executives from North America, LATAM, APAC, and EMEA—all in VP or C-level positions at organizations with over 1,000 employees—the report paints a current picture of modern security validation prac

The official website of a prominent Israel-based, Middle East foreign policy-focused think tank, the Jerusalem Center for Public Affairs (JCPA) , has been compromised and abused by attackers to distribute malware . The Israeli think tank website JCPA – an independent research institute focusing on Israeli security, regional diplomacy and international law – was serving the Sweet Orange exploit kit via drive-by downloads to push malware onto the computers of the website's visitors by exploiting software vulnerabilities, researchers from security firm Cyphort reported on Friday. The Sweet Orange is one of the most recently released web malware exploitation kits, available for sale at selected invite-only cyber crime friendly communities and has been around for quite some time. However, Sweet Orange has also disappeared but in October 2013, shortly after the arrest of Paunch, the author of BlackHole , experts observed a major increase in the use of Sweet Orange. The

As far, you have probably heard about the biggest digital exposure of private and very personal nude photographs of as many as 100 female celebrities including Jenny McCarthy, Kristin Dunst, Mary E Winstead, and Oscar winner Lawrence and Kate Upton, that was surfaced on notorious bulletin-board 4chan, and anonymous image board AnonIB over the weekend. It was believed that the group of hackers allegedly taken celebrities photos from their Apple iCloud backups after their iCloud accounts were compromised, but users of devices running Google's Android could have been targeted too. A forum post on anonymous image board AnonIP shows that the group of hackers may have used a cloned Flappy Bird app to steal and collect the naked photos of females from their Android devices and then send them to remote servers. Experts believe that the group may have been stealing and trading nude and very personal photos of more than 100 female celebrities for more than two years, gather

Researchers have uncovered a new social engineering trick that leads users to a malicious extension from Google Chrome impersonating to deliver Adobe's Flash Player in order to lure victims in a click fraud campaign. Security experts at TrendMicro believe that the malware is triggered by opening Facebook or Twitter via shortened links provided in any social networking websites. Once clicked, the links may lead victims to a site that automatically downloads the malicious browser extension . MALWARE INVOLVES DOWNLOADING MULTIPLE MALICIOUS FILES The process is quite complicated as the malware drops a downloader file which downloads multiple malicious files on the victim's computer. Moreover, the malicious program also has ability to bypass Google's recent security protection added to Chrome against installation of browser extensions that are not in Chrome Web Store. Researchers came across a baiting tweet that advertises " Facebook Secrets ", claiming to show videos

Till now we have seen a series of different malware targeting Windows operating system and not Mac, thanks to Apple in way it safeguard its devices' security. But with time, cyber criminals and malware authors have found ways to exploit Mac as well. GROUP BEHIND THE MAC VERSION OF BACKDOOR Researchers have unmasked a group of cyber criminals that has recently started using a new variant of XSLCmd backdoor program to target Mac OS X systems. This Mac version of backdoor shares a significant portion of its code with the Windows version of the same backdoor that has been around since at least 2009. According to FireEye researchers, the group, dubbed as GREF , is already infamous for its past cyber espionage attacks against the US Defense Industrial Base (DIB), companies from the electronics and engineering sectors worldwide, foundations and other NGO's as well. " We track this threat group as "GREF" due to their propensity to use a variety of Google references in th

A New York-based online ad network company AppNexus, that provides a platform specializing in real-time online advertising, has again been spotted as the origin of a recent "malvertising" campaign that makes use of the Angler Exploit Kit to redirect visitors to malicious websites hosting the Asprox malware. AppNexus servers process 16 billion ad buys per day, making it the biggest reach on the open web after Google. Back in May, AppNexus was serving malicious ads targeting Microsoft's Silverlight platform. The world's largest Internet Video Subscription service Netflix runs on Silverlight, and because of its popularity, hackers have been loading exploit kits with Silverlight. As part of this campaign, users of several high-profile websites including Java.com, Deviantart.com, TMZ.com, Photobucket.com, IBTimes.com, eBay.ie, Kapaza.be and TVgids.nl , last week were redirected to websites serving malicious advertisements that infected visitors by installing botnet ma

If you have jailbroken your iPhone, iPad, or iPod touch and have downloaded pirated tweaks from pirated repositories, then you may be infected by "AdThief" malware, a Chinese malware that is now installed on more than 75,000 iPhone devices. According to a recent research paper published on Virus Bulletin by the Security Researcher Axelle Apvrille , the malware, also known as " spad ," was first discovered by security researcher Claud Xiao in March this year. Till now, AdThief aka Spad malware has hijacked an estimated 22 million advertisements and stealing revenue from developers on the iOS jailbreak community, Axelle Apvrille says. The malware allegedly infects iOS jailbroken devices by disguising itself as Cydia Substrate extension, presents only on jailbroken Apple devices, when a malware infected Cydia package is downloaded and installed by the unsuspecting user. Once installed, the malware modifies certain advertisements displayed on your iOS devi

Before proceeding towards the story, let's first go back two years to figure out what was wrong when Syria was completely blackout - sudden disconnect from the Internet - which lasted for the period of three days in 2012. Is that the Syrian government behind the blackout ? The outage took place during a period of intense fighting in the country's still-ongoing civil war. So, it was supposed that may it be the government's fault. But, the Syrian Minister of Information said that the government didn't disable the Internet, instead the outage was caused by a cable being cut by some terrorists. When investigated, it was unlikely to be the case. So, Who was actually behind Syria Blackout ? NSA? Yup! It was the same NSA who was behind a number of major happenings. National Security Agency ( NSA ) – the God-like powered agency that had ruled over the privacy of the entire world from countries to individuals, the one with master access to read anyone's data, intruded into larg

Scammers have again targeted more than one billion active users of the popular social networking giant Facebook, to infect as many victims as possible. This time, an old Facebook scam is back in action once again! Malicious Facebook "Color Changer" app has resurfaced again on the popular social networking site Facebook, this time compromising more than 10,000 people worldwide. The malicious app promises users to change the characteristic blue colour of Facebook's header and interface to one of nine other colours including pink, purple, green, yellow, orange and black, in order to infect users' phones and computers with malicious software. Researchers at China-based Internet company Cheetah Mobile have detected the " Facebook colour changer " that tricks Facebook users into downloading the app via a malicious phishing site. The phishing website targets users in two ways: First of all, it steals the users' Facebook Access Tokens by asking them

FinFisher spyware, a spyware application used by government and law enforcement agencies for the purpose of surveillance, appears to have been hacked earlier this week and a string of files has been dumped on the Internet. The highly secret surveillance software called " FinFisher " sold by British company Gamma International can secretly monitors computers by turning ON webcams, recording everything the user types with a keylogger, and intercepting Skype calls, copying files, and much more. A hacker has claimed on Reddit and Twitter that they'd infiltrated the network of one of the world's top surveillance & motoring technology company Gamma International, creator of FinFisher spyware, and has exposed 40GB of internal data detailing the operations and effectiveness of the FinFisher suite of surveillance platforms. The leaked information was published both on a parody Gamma Group Twitter account ( @GammaGroupPR ) and Reditt by the hacker that began publishi

When I say Ransomware, the first nasty piece of malware strikes in the mind is CryptoLocker . A nasty strain of ransomware malware that threatened most of the people around the world by effectively destroying important files of the victims forever. CRYPTOLOCKER - A DEVASTATING THREAT CryptoLocker is a simple rather a devastating piece of Ransomware that encrypts the files on a victim's computer and issues an ultimatum - Pay up or lose your data. CryptoLocker is particularly designed to extort money from computer users by holding computer files hostage until the computer user pays a ransom fee to get them back. Cryptolocker hijacker sniffs out your personal files and wraps them with strong AES-256-bit encryption before it demands money. HOW TO DECRYPT CRYPTOLOCKER? FREE TOOL RELEASED Thanks to security experts, who created an online service where victims whose systems have been encrypted by the CryptoLocker ransomware can get the decryption keys for free. This o

Tor has always been a tough target for law enforcement for years, but the United States Federal Bureau of Investigation ( FBI ) has found a way to successfully track users across the network. Just a few days back, Tor made a difficult announcement that an attack on its system likely exposed its users of anonymity. Now, a new report from Wired suggests that the FBI has been running a malware campaign to identify Tor users by infecting their computers for years on a large scale. FBI USES DRIVE-BY HACKING TO TRACK USERS Tor is generally thought to be a place where users come online to hide their activities and remain anonymous, but a court case has revealed an opposite story. FBI has been using a tactic called drive-by hacking to track computers using the Tor anonymous computing system. Security researchers call the tactic a " drive-by download " in which a hacker infiltrates a high-traffic website to deliver the malware to large swaths of visitors. That simply means t

If we talk about old days, a hacker often rely on the natural helpfulness as well as weaknesses of people whom he wanted to target. This tactic to break into a computer network by gaining the confidence of an authorized user and get them to reveal information that compromises the network's security is known as Social Engineering . WHAT IS SOCIAL ENGINEERING Social engineering is nothing but a non technical kind of intrusion that relies heavily on human interaction and involves manipulating people so they give up confidential information. Social engineering was very effective those old days as well as today, as major targets are made victims using this old trick only and it is also one of the important components of many types of exploits like: Virus writers use social engineering tactics to persuade people to run malicious email attachments Phishers use social engineering tactics to convince people to disclose their sensitive information such as banking credentia

Researchers have warned users of Android devices to avoid app downloads from particularly unauthorized sources, since a new and sophisticated piece of malware is targeting Android users through phishing emails . The malware, dubbed SandroRAT , is currently being used by cybercriminals to target Android users in Poland via a widely spread email spam campaign that delivers a new variant of an Android remote access tool (RAT). The emails masquerade itself as a bank alert that warns users of the malware infection in their mobile device and offers a fake mobile security solution in order to get rid of the malware infection. The mobile security solution poses as a Kaspersky Mobile Security , but in real, it is a version of SandroRAT, a remote access tool devised for Android devices, whose source code has been put on sale on underground Hack Forums since December last year. A mobile malware researcher at McAfee, Carlos Castillo, detailed the new variant of Android remot

Malware is nothing but a malicious files which is stored on an infected computer system in order to damage the system or steal sensitive data from it or perform other malicious activities. But security researchers have uncovered a new and sophisticated piece of malware that infects systems and steals data without installing any file onto the targeted system. Researchers dubbed this  persistent malware as Poweliks , which resides in the computer registry only and is therefore not easily detectable as other typical malware that installs files on the affected system which can be scanned by antivirus or anti-malware Software. According to Paul Rascagneres , Senior Threat Researcher, Malware analyst at GData software, due to the malware's subsequent and step-after-step execution of code, the feature set was similar to a stacking principles of Matryoshka Doll approach. Paul has made a number of name ripping malware and bots to uncover and undermine cyber crimes. He won last

Due to the majority in the mobile platform, Google's Android operating system has been a prior target for cybercriminals and a recently exposed weakness in the way the operating system handles certificate validation, left millions of Android devices open to attack. Researchers at BlueBox security , who identified the vulnerability, dubbed the flaw as Fake ID , which affects all versions of Android operating system from 2.1 ( released in 2010 ) up to Android 4.4, also known as KitKat . ALL VERSIONS ARE VULNERABLE UPTO KITKAT Researchers marked the vulnerability as critical because it could allow a fake and malicious app to masquerade as a legitimate and trusted application, enabling an attacker to perform various actions such as inserting malicious code into a legitimate app, infiltrating your personal information or even take complete control of an affected device. Specifically, devices running the 3LM administration extension are at risk for a complete compromise, whic
