First-Ever Ransomware Found Using ‘Process Doppelgänging’ Attack to Evade Detection

May 07, 2018Mohit Kumar
Security researchers have spotted the first-ever ransomware exploiting Process Doppelgänging , a new fileless code injection technique that could help malware evade detection. The Process Doppelgänging attack takes advantage of a built-in Windows function, i.e., NTFS Transactions, and an outdated implementation of Windows process loader, and works on all modern versions of Microsoft Windows OS, including Windows 10. Process Doppelgänging attack works by using NTFS transactions to launch a malicious process by replacing the memory of a legitimate process, tricking process monitoring tools and antivirus into believing that the legitimate process is running. If you want to know more about how Process Doppelgänging attack works in detail, you should read this article  I published late last year. Shortly after the Process Doppelgänging attack details went public, several threat actors were found abusing it in an attempt to bypass modern security solutions. Security researchers
New Cryptocurrency Mining Malware Infected Over 500,000 PCs in Just Few Hours

New Cryptocurrency Mining Malware Infected Over 500,000 PCs in Just Few Hours

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

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

Dynamic Analysis tools for Android Fail to Detect Malware with Heuristic Evasion Techniques

May 14, 2014Mohit Kumar
We are quite aware of the Android malware scanner Google’s Bouncer that tests the apps by running them in a virtualized environment i.e. a simulated phone created in software which automatically scans the apps to watch its real behaviour on users’ devices, before approving them to the Play Store market. To protect its users and their devices from harm, Google launched this apps scanning software tool, two year ago. Bouncer is a security feature for the Android Play store Market that is designed to protect the Android users to not to be a victim of any malicious Android malware app. But does the security tool go far enough? Despite having protective shield factor, we have seen Google play store market is surrounded by many malicious apps which easily by-passes the Bouncer scan test and targets Android users. Security Research from Columbia University have exploited weaknesses in Google's Bouncer service to sneak malicious apps on to the Android market. They publish

Today I desire to propose an interview with Andrey Komarov , CEO of IntelCrawler and Dan Clements , President of IntelCrawler. IntelCrawler  is a multi-tier intelligence aggregator, which gathers information and cyber prints from a starting big data pool of over 3, 000, 000, 000 IPv4 and over 200, 000, 000 domain names, which are scanned for analytics and dissemination to drill down to a desired result. I have prepared for them a series of answers and questions to analyze significant evolutions in the cyber-threat landscape: Q. Which are the most concerning cyber threats for private businesses and government organizations? A. Avoiding talking about usual and standard things, of course, the most dangerous and annoying is the emergence of fundamentally new vulnerabilities in critical applications and systems. " Zero day " vulnerabilities market is developing every day and taking the shape of a part of the future cyber warfare market , as it is still in the process of formati
