New MacOS Malware, Signed With Legit Apple ID, Found Spying On HTTPS Traffic

April 28, 2017Swati Khandelwal
Many people believe that they are much less likely to be bothered by malware if they use a Mac computer, but is it really true? Unfortunately, No. According to the McAfee Labs , malware attacks on Apple's Mac computers were up 744% in 2016, and its researchers have discovered nearly 460,000 Mac malware samples, which is still just a small part of overall Mac malware out in the wild. Today, Malware Research team at CheckPoint have discovered a new piece of fully-undetectable Mac malware, which according to them, affects all versions of Mac OS X, has zero detections on VirusTotal and is "signed with a valid developer certificate (authenticated by Apple)." Dubbed DOK , the malware is being distributed via a coordinated email phishing campaign and, according to the researchers, is the first major scale malware to target macOS users. The malware has been designed to gain administrative privileges and install a new root certificate on the target system, which allows

Yet Another Android Malware Infects Over 4.2 Million Google Play Store Users

Yet Another Android Malware Infects Over 4.2 Million Google Play Store Users

September 15, 2017Swati Khandelwal
Even after so many efforts by Google, malicious apps somehow managed to fool its Play Store's anti-malware protections and infect people with malicious software. The same happened once again when at least 50 apps managed to make its way onto Google Play Store and were successfully downloaded as many as 4.2 million times—one of the biggest malware outbreaks. Security firm Check Point on Thursday published a blog post revealing at least 50 Android apps that were free to download on official Play Store and were downloaded between 1 million and 4.2 million times before Google removed them. These Android apps come with hidden malware payload that secretly registers victims for paid online services, sends fraudulent premium text messages from victims' smartphones and leaves them to pay the bill—all without the knowledge or permission of users. Dubbed ExpensiveWall by Check Point researchers because it was found in the Lovely Wallpaper app, the malware comes hidden in fre

Malware Hijacks Microphones to Spy On Ukrainian Businesses, Scientists and Media

February 21, 2017Swati Khandelwal
Ukraine has once again been a target of a potential hacking attack that infected computer systems from dozens of Ukrainian businesses with highly sophisticated malware, allowing hackers to exfiltrate sensitive data and eavesdrop on their network. Late last year, the country also suffered a power outage caused by the same group of hackers that targeted Ukraine's power grid with the BlackEnergy malware in late 2015, causing 225,000 residents to lose electricity. Now security researchers from threat intelligence firm CyberX have uncovered an advanced malware-based operation that has already siphoned over 600 gigabytes of data from about 70 victim organizations, including critical infrastructure, news media, and scientific research. Operation BugDrop: Damages and Modus Operandi Dubbed " Operation BugDrop ," the large-scale malware campaign has been perpetrated against targets in the Ukraine, though targets from other countries include Russia, Saudi Arabia, and Austr
The Rise of Super-Stealthy Digitally Signed Malware—Thanks to the Dark Web

The Rise of Super-Stealthy Digitally Signed Malware—Thanks to the Dark Web

November 06, 2017Swati Khandelwal
Guess what's more expensive than counterfeit United States passports, stolen credit cards and even guns on the dark web? It's digital code signing certificates. A recent study conducted by the Cyber Security Research Institute (CSRI) this week revealed that stolen digital code-signing certificates are readily available for anyone to purchase on the dark web for up to $1,200. As you may know, digital certificates issued by a trusted certificate authority (CA) are used to cryptographically sign computer applications and software, and are trusted by your computer for execution of those programs without any warning messages. However, malware author and hackers who are always in search of advanced techniques to bypass security solutions have been abusing trusted digital certificates during recent years. Hackers use compromised code signing certificates associated with trusted software vendors in order to sign their malicious code, reducing the possibility of their malw
New Point-of-Sale Malware Steals Credit Card Data via DNS Queries

New Point-of-Sale Malware Steals Credit Card Data via DNS Queries

February 09, 2018Swati Khandelwal
Cybercriminals are becoming more adept, innovative, and stealthy with each passing day. They are now adopting more clandestine techniques that come with limitless attack vectors and are harder to detect. A new strain of malware has now been discovered that relies on a unique technique to steal payment card information from point-of-sale (PoS) systems. Since the new POS malware relies upon User Datagram Protocol (UDP) DNS traffic for the exfiltration of credit card information, security researchers at Forcepoint Labs, who have uncovered the malware, dubbed it UDPoS . Yes, UDPoS uses Domain Name System (DNS) queries to exfiltrate stolen data, instead of HTTP that has been used by most POS malware in the past. This malware is also thought to be first of its kind. Besides using 'unusual' DNS requests to exfiltrate data, the UDPoS malware disguises itself as an update from LogMeIn —a legitimate remote desktop control service used to manage computers and other systems remo

Dangerous Malware Discovered that Can Take Down Electric Power Grids

June 12, 2017Swati Khandelwal
Last December, a cyber attack on Ukrainian Electric power grid caused the power outage in the northern part of Kiev — the country's capital — and surrounding areas, causing a blackout for tens of thousands of citizens for an hour and fifteen minutes around midnight. Now, security researchers have discovered the culprit behind those cyber attacks on the Ukrainian industrial control systems. Slovakia-based security software maker ESET and US critical infrastructure security firm Dragos Inc. say they have discovered a new dangerous piece of malware in the wild that targets critical industrial control systems and is capable of causing blackouts. Dubbed " Industroyer " or " CrashOverRide ," the grid-sabotaging malware was likely to be used in the December 2016 cyber attack against Ukrainian electric utility Ukrenergo , which the security firms say represents a dangerous advancement in critical infrastructure hacking. According to the researchers, CrashO

A newly uncovered malware strain has already infected more than 14 Million Android devices around the world, earning its operators approximately $1.5 Million in fake ad revenues in just two months. Dubbed CopyCat , the malware has capabilities to root infected devices, establish persistency, and inject malicious code into Zygote – a daemon responsible for launching apps on Android, providing the hackers full access to the devices. Over 14 Million Devices Infected; 8 Million of them Rooted According to the security researchers at Check Point who discovered this malware strain, CopyCat malware has infected 14 million devices, rooted nearly 8 million of them, had 3.8 million devices serve ads, and 4.4 million of them were used to steal credit for installing apps on Google Play. While the majority of victims hit by the CopyCat malware resides in South and Southeast Asia with India being the most affected country, more than 280,000 Android devices in the United States were al

Unveiled: How xHelper Android Malware Re-Installs Even After Factory Reset

April 07, 2020Mohit Kumar
Remember xHelper? A mysterious piece of Android malware that re-installs itself on infected devices even after users delete it or factory reset their devices—making it nearly impossible to remove. xHelper reportedly infected over 45,000 devices last year, and since then, cybersecurity researchers have been trying to unfold how the malware survives factory reset and how it infected so many devices in the first place. In a blog post published today, Igor Golovin, malware analyst at Kaspersky, finally solved the mystery by unveiling technical details on the persistence mechanism used by this malware, and eventually also figured out how to remove xHelper from an infected device completely. As the initial attack vector and for distribution, the malware app disguises itself as a popular cleaner and speed optimization app for smartphones — affecting mostly users in Russia (80.56%), India (3.43%), and Algeria (2.43%). "But in reality, there is nothing useful about it: af

Over the past few months, hundreds of Android users have been complaining online of a new piece of mysterious malware that hides on the infected devices and can reportedly reinstall itself even after users delete it, or factory reset their devices. Dubbed Xhelper , the malware has already infected more than 45,000 Android devices in just the last six months and is continuing to spread by infecting at least 2,400 devices on an average each month, according to the latest report published today by Symantec. Here below, I have collected excerpts from some comments that affected users shared on the online forums while asking for how to remove the Xhelper Android malware: "xhelper regularly reinstalls itself, almost every day!" "the 'install apps from unknown sources' setting turns itself on." "I rebooted my phone and also wiped my phone yet the app xhelper came back." "Xhelper came pre-installed on the phone from China."
GandCrab ransomware and Ursnif virus spreading via MS Word macros

GandCrab ransomware and Ursnif virus spreading via MS Word macros

January 25, 2019Swati Khandelwal
Security researchers have discovered two separate malware campaigns, one of which is distributing the Ursnif data-stealing trojan and the GandCrab ransomware in the wild, whereas the second one is only infecting victims with Ursnif malware. Though both malware campaigns appear to be a work of two separate cybercriminal groups, we find many similarities in them. Both attacks start from phishing emails containing an attached Microsoft Word document embedded with malicious macros and then uses Powershell to deliver fileless malware. Ursnif is a data-stealing malware that typically steals sensitive information from compromised computers with an ability to harvest banking credentials, browsing activities, collect keystrokes, system and process information, and deploy additional backdoors. Discovered earlier last year, GandCrab is a widespread ransomware threat that, like every other ransomware in the market, encrypts files on an infected system and insists victims to pay a ransom

FBI issues alert over two new malware linked to Hidden Cobra hackers

May 30, 2018Swati Khandelwal
The US-CERT has released a joint technical alert from the DHS and the FBI, warning about two newly identified malware being used by the prolific North Korean APT hacking group known as Hidden Cobra. Hidden Cobra, often known as Lazarus Group and Guardians of Peace, is believed to be backed by the North Korean government and known to launch attacks against media organizations, aerospace, financial and critical infrastructure sectors across the world. The group was even associated with the WannaCry ransomware menace that last year shut down hospitals and businesses worldwide. It is reportedly also linked to the 2014 Sony Pictures hack , as well as the SWIFT Banking attack in 2016. Now, the Department of Homeland Security (DHS) and the FBI have uncovered two new pieces of malware that Hidden Cobra has been using since at least 2009 to target companies working in the media, aerospace, financial, and critical infrastructure sectors across the world. The malware Hidden Cobra is
