7 Chrome Extensions Spreading Through Facebook Caught Stealing Passwords

May 11, 2018Swati Khandelwal
Luring users on social media to visit lookalike version of popular websites that pop-up a legitimate-looking Chrome extension installation window is one of the most common modus operandi of cybercriminals to spread malware. Security researchers are again warning users of a new malware campaign that has been active since at least March this year and has already infected more than 100,000 users worldwide. Dubbed Nigelthorn, the malware is rapidly spreading through socially engineered links on Facebook and infecting victims’ systems with malicious browser extensions that steal their social media credentials, install cryptocurrency miners, and engage them in click fraud. The malware was pushed through at least seven different Chrome browser extensions—all were hosted on Google's official Chrome Web Store. These malicious Chrome browser extensions were first discovered by researchers at cybersecurity firm Radware, after a "well-protected network" of one of its custo

If you receive a link for a video, even if it looks exciting, sent by someone (or your friend) on Facebook messenger—just don't click on it without taking a second thought. Cybersecurity researchers from Trend Micro are warning users of a malicious Chrome extension which is spreading through Facebook Messenger and targeting users of cryptocurrency trading platforms to steal their accounts’ credentials. Dubbed FacexWorm , the attack technique used by the malicious extension first emerged in August last year, but researchers noticed the malware re-packed a few new malicious capabilities earlier this month. New capabilities include stealing account credentials from websites, like Google and cryptocurrency sites, redirecting victims to cryptocurrency scams, injecting miners on the web page for mining cryptocurrency, and redirecting victims to the attacker's referral link for cryptocurrency-related referral programs. It is not the first malware to abuse Facebook Messenger
How to Steal Bitcoin Wallet Keys (Cold Storage) from Air-Gapped PCs

How to Steal Bitcoin Wallet Keys (Cold Storage) from Air-Gapped PCs

April 24, 2018Wang Wei
Dr. Mordechai Guri, the head of R&D team at Israel's Ben Gurion University, who previously demonstrated various methods to steal data from an air-gapped computer, has now published new research named " BeatCoin ." BeatCoin is not a new hacking technique; instead, it's an experiment wherein the researcher demonstrates how all previously discovered out-of-band communication methods can be used to steal private keys for a cryptocurrency wallet installed on cold storage, preferably an air-gapped computer or Raspberry Pi. For those unaware, keeping your cryptocurrency protected in a wallet on a device which is entirely offline is called cold storage. Since online digital wallets carry different security risks, some people prefer keeping their private keys offline. Air-gapped computers are those that are isolated from the Internet, local networks, Bluetooth and therefore, are believed to be the most secure devices and are difficult to infiltrate or exfiltrate.

Security researchers have uncovered a new hacking group that is aggressively targeting healthcare organizations and related sectors across the globe to conduct corporate espionage. Dubbed " Orangeworm ," the hacking group has been found installing a wormable trojan on machines hosting software used for controlling high-tech imaging devices, such as X-Ray and MRI machines, as well as machines used to assist patients in completing consent forms. According to a new report  published by Symantec on Monday, the Orangeworm hacking group has been active since early 2015 and targeting systems of major international corporations based in the United States, Europe, and Asia with a primary focus on the healthcare sector. "We believe that these industries have also been targeted as part of a larger supply-chain attack in order for Orangeworm to get access to their intended victims related to healthcare," Symantec said. After getting into the victim's network, atta

If you have installed any of the below-mentioned Ad blocker extension in your Chrome browser, you could have been hacked. A security researcher has spotted five malicious ad blockers extension in the Google Chrome Store that had already been installed by at least 20 million users. Unfortunately, malicious browser extensions are nothing new. They often have access to everything you do online and could allow its creators to steal any information victims enter into any website they visit, including passwords, web browsing history and credit card details. Discovered by Andrey Meshkov, co-founder of Adguard, these five malicious extensions are copycat versions of some legitimate, well-known Ad Blockers. Creators of these extensions also used popular keywords in their names and descriptions to rank top in the search results, increasing the possibility of getting more users to download them. "All the extensions I've highlighted are simple rip-offs with a few lines of co

April 18, 2018Swati Khandelwal
Last year, the popular system cleanup software CCleaner suffered a massive supply-chain malware attack of all times, wherein hackers compromised the company's servers for more than a month and replaced the original version of the software with the malicious one. The malware attack infected over 2.3 million users who downloaded or updated their CCleaner app between August and September last year from the official website with the backdoored version of the software. Now, it turns out that the hackers managed to infiltrate the company's network almost five months before they first replaced the official CCleaner build with the backdoored version, revealed Avast executive VP and CTO Ondrej Vlcek at the RSA security conference in San Francisco on Tuesday. 6-Months Timeline of CCleaner Supply Chain Attack Vlcek shared a brief timeline of the last year's incident that came out to be the worst nightmare for the company, detailing how and when unknown hackers breached Pi

Cybercriminals Hijack Router DNS to Distribute Android Banking Trojan

April 16, 2018Swati Khandelwal
Security researchers have been warning about an ongoing malware campaign hijacking Internet routers to distribute Android banking malware that steals users' sensitive information, login credentials and the secret code for two-factor authentication. In order to trick victims into installing the Android malware, dubbed Roaming Mantis , hackers have been hijacking DNS settings on vulnerable and poorly secured routers . DNS hijacking attack allows hackers to intercept traffic, inject rogue ads on web-pages and redirect users to phishing pages designed to trick them into sharing their sensitive information like login credentials, bank account details, and more. Hijacking routers' DNS for a malicious purpose is not new. Previously we reported about widespread DNSChanger and Switcher —both the malware worked by changing the DNS settings of the wireless routers to redirect traffic to malicious websites controlled by attackers. Discovered by security researchers at Kaspersk
Hackers Found Using A New Code Injection Technique to Evade Detection

Hackers Found Using A New Code Injection Technique to Evade Detection

April 13, 2018Mohit Kumar
While performing in-depth analysis of various malware samples, security researchers at Cyberbit found a new code injection technique, dubbed Early Bird , being used by at least three different sophisticated malware that helped attackers evade detection. As its name suggests, Early Bird is a "simple yet powerful" technique that allows attackers to inject malicious code into a legitimate process before its main thread starts, and thereby avoids detection by Windows hook engines used by most anti-malware products. The Early Bird code injection technique "loads the malicious code in a very early stage of thread initialization, before many security products place their hooks—which allows the malware to perform its malicious actions without being detected," the researchers said. The technique is similar to the AtomBombing code injection technique that does not rely on easy-to-detect API calls, allowing malware to inject code into processes in a manner that no a

Microsoft Office 365 Gets Built-in Ransomware Protection and Enhanced Security Features

April 06, 2018Mohit Kumar
Ransomware has been around for a few years, but it has become an albatross around everyone's neck, targeting big businesses, hospitals, financial institutions and individuals worldwide and extorting millions of dollars. Last year, we saw some major ransomware outbreaks, including WannaCry  and  NotPetya , which wreaked havoc across the world, hitting hundreds of thousands of computers and business networks worldwide. From small to mid-range businesses, Microsoft Office 365 remains the most widely used and fastest-growing work office suite, so it's no surprise that it has become a primary target for viruses, ransomware, and phishing scams. In fact, most strains of ransomware target Microsoft productivity apps such as Word, Excel and encrypt sensitive data to hold the company hostage until the ransom is paid. Now, to combat such cyber attacks, Microsoft has announced some new security features for Office 365 that can help users mitigate the damage done by ransomware a

Security researchers at Cisco Talos have uncovered variants of a new Android Trojan that are being distributed in the wild disguising as a fake anti-virus application, dubbed "Naver Defender." Dubbed KevDroid , the malware is a remote administration tool (RAT) designed to steal sensitive information from compromised Android devices, as well as capable of recording phone calls. Talos researchers published Monday technical details about two recent variants of KevDroid detected in the wild, following the initial discovery of the Trojan by South Korean cybersecurity firm ESTsecurity two weeks ago. Though researchers haven't attributed the malware to any hacking or state-sponsored group, South Korean media have linked KevDroid with North Korea state-sponsored cyber espionage hacking group " Group 123 ," primarily known for targeting South Korean targets. The most recent variant of KevDroid malware, detected in March this year, has the following capabilit

Trojanized BitTorrent Software Update Hijacked 400,000 PCs Last Week

March 14, 2018Swati Khandelwal
A massive malware outbreak that last week infected nearly half a million computers with cryptocurrency mining malware in just a few hours was caused by a backdoored version of popular BitTorrent client called MediaGet . Dubbed Dofoil (also known as Smoke Loader), the malware was found dropping a cryptocurrency miner program as payload on infected Windows computers that mine Electroneum digital coins for attackers using victims' CPU cycles. Dofoil campaign that hit PCs in Russia, Turkey, and Ukraine on 6th March was discovered by Microsoft Windows Defender research department and blocked the attack before it could have done any severe damages. At the time when Windows Defender researchers detected this attack, they did not mention how the malware was delivered to such a massive audience in just 12 hours. However, after investigation Microsoft today revealed that the attackers targeted the update mechanism of MediaGet BitTorrent software to push its trojanized version (m

13 Critical Flaws Discovered in AMD Ryzen and EPYC Processors

March 13, 2018Swati Khandelwal
Security researchers claimed to have discovered 13 critical Spectre/Meltdown -like vulnerabilities throughout AMD's Ryzen and EPYC lines of processors that could allow attackers to access sensitive data, install persistent malware inside the chip, and gain full access to the compromised systems. All these vulnerabilities reside in the secure part of the AMD's Zen architecture processors and chipsets—typically where device stores sensitive information such as passwords and encryption keys and makes sure nothing malicious is running when you start your PC. The alleged vulnerabilities are categorized into four classes—RYZENFALL, FALLOUT, CHIMERA, and MASTERKEY—and threaten wide-range of servers, workstations, and laptops running vulnerable AMD Ryzen, Ryzen Pro, Ryzen Mobile or EPYC processors. Discovered by a team of researchers at Israel-based CTS-Labs, newly disclosed  unpatched vulnerabilities defeat AMD's Secure Encrypted Virtualization (SEV) technology and could
MOSQUITO Attack Allows Air-Gapped Computers to Covertly Exchange Data

MOSQUITO Attack Allows Air-Gapped Computers to Covertly Exchange Data

March 12, 2018Mohit Kumar
The team of security researchers—who last month demonstrated how attackers could steal data from air-gapped computers protected inside a Faraday cage—are back with its new research showing how two (or more) air-gapped PCs placed in the same room can covertly exchange data via ultrasonic waves. Air-gapped computers are believed to be the most secure setup wherein the systems remain isolated from the Internet and local networks, requiring physical access to access data via a USB flash drive or other removable media. Dubbed MOSQUITO , the new technique, discovered by a team of researchers at Israel's Ben Gurion University, works by reversing connected speakers (passive speakers, headphones, or earphones) into microphones by exploiting a specific audio chip feature. Two years ago, the same team of researchers demonstrated how attackers could covertly listen to private conversations in your room just by reversing your headphones (connected to the infected computer) into a micr

ISPs Caught Injecting Cryptocurrency Miners and Spyware In Some Countries

March 09, 2018Swati Khandelwal
Governments in Turkey and Syria have been caught hijacking local internet users' connections to secretly inject surveillance malware, while the same mass interception technology has been found secretly injecting browser-based cryptocurrency mining scripts into users' web traffic in Egypt. Governments, or agencies linked to it, and ISPs in the three countries are using Deep Packet Inspection technology from Sandvine (which merged with Procera Networks last year), to intercept and alter Internet users' web traffic. Deep packet inspection technology allows ISPs to prioritize, degrade, block, inject, and log various types of Internet traffic, in other words, they can analyze each packet in order to see what you are doing online. According to a new report by Citizen Lab, Turkey's Telecom network was using Sandvine PacketLogic devices to redirect hundreds of targeted users (journalists, lawyers, and human rights defenders) to malicious versions of legitimate progra

Two days ago, Microsoft encountered a rapidly spreading cryptocurrency-mining malware that infected almost 500,000 computers within just 12 hours and successfully blocked it to a large extent. Dubbed Dofoil , aka Smoke Loader , the malware was found dropping a cryptocurrency miner program as payload on infected Windows computers that mines Electroneum coins, yet another cryptocurrency, for attackers using victims' CPUs. On March 6, Windows Defender suddenly detected more than 80,000 instances of several variants of Dofoil that raised the alarm at Microsoft Windows Defender research department, and within the next 12 hours, over 400,000 instances were recorded. The research team found that all these instances, rapidly spreading across Russia, Turkey, and Ukraine, were carrying a digital coin-mining payload, which masqueraded as a legitimate Windows binary to evade detection. However, Microsoft has not mentioned how these instances were delivered to such a massive audienc

Hacker Who Never Hacked Anyone Gets 33-Month Prison Sentence

February 27, 2018Mohit Kumar
A hacker who was arrested and pleaded guilty last year—not because he hacked someone, but for creating and selling a remote access trojan that helped cyber criminals—has finally been sentenced to serve almost three years in prison. Taylor Huddleston, 26, of Hot Springs, Arkansas, pleaded guilty in July 2017 to one charge of aiding and abetting computer intrusions by building and intentionally selling a remote access trojan (RAT), called NanoCore , to hackers for $25. Huddleston was arrested in March, almost two months before the FBI raided his house in Hot Springs, Arkansas and left with his computers after 90 minutes, only to return eight weeks later with handcuffs. This case is a rare example of the US Department of Justice (DOJ) charging someone not for actively using malware to hack victims' computers, but for developing and selling it to other cybercriminals. Huddleston admitted to the court that he created his software knowing it would be used by other cybercrimi
