Operator of VirusTotal Like Malware-Scanning Service Jailed for 14 Years

September 22, 2018Mohit Kumar
A Latvian hacker behind the development and operation of counter antivirus service "Scan4You" has finally been sentenced to 14 years in prison. 37-year-old Ruslans Bondars, described as a Latvian "non-citizen" or "citizen of the former USSR who had been residing in Riga, Latvia," was found guilty on May 16 in federal court in Alexandria, during which a co-conspirator revealed he had worked with Russian law enforcement. Bondars created and ran Scan4you—a VirusTotal like online multi-engine antivirus scanning service that allowed hackers to run their code by several popular antiviruses to determine if their computer virus or malware would be flagged during routine security scans before launching them into a real-world malware campaign. While legal scanning services share data about uploaded files with the antivirus firms, Scan4you instead informed its users that they could "upload files anonymously and promised not to share information about the
WikiLeaks Reveals 'Marble' Source Code that CIA Used to Frame Russia and China

WikiLeaks Reveals 'Marble' Source Code that CIA Used to Frame Russia and China

March 31, 2017Mohit Kumar
WikiLeaks published hundreds of more files from the Vault 7 series today which, it claims, show how CIA can mask its hacking attacks to make it look like it came from other countries, including Russia, China, North Korea and Iran. Dubbed " Marble ," the part 3 of CIA files contains 676 source code files of a secret anti-forensic Marble Framework, which is basically an obfuscator or a packer used to hide the true source of CIA malware. The CIA's Marble Framework tool includes a variety of different algorithm with foreign language text intentionally inserted into the malware source code to fool security analysts and falsely attribute attacks to the wrong nation. The leaked files indicate that the Marble's source code includes Chinese, Russian, Korean, Arabic and Farsi languages, as well as English, which shows that the CIA has engaged in clever hacking games. "Marble is used to hamper[ing] forensic investigators and anti-virus companies from attributin
New “Fileless Malware” Targets Banks and Organizations Spotted in the Wild

New "Fileless Malware" Targets Banks and Organizations Spotted in the Wild

February 08, 2017Swati Khandelwal
More than a hundred banks and financial institutions across the world have been infected with a dangerous sophisticated, memory-based malware that's almost undetectable, researchers warned. Newly published report by the Russian security firm Kaspersky Lab indicates that hackers are targeting banks, telecommunication companies, and government organizations in 40 countries, including the US, South America, Europe and Africa, with Fileless malware that resides solely in the memory of the compromised computers. Fileless malware was first discovered by the same security firm in 2014, has never been mainstream until now. Fileless malware is a piece of nasty software that does not copy any files or folder to the hard drive in order to get executed. Instead, payloads are directly injected into the memory of running processes, and the malware executes in the system's RAM. Since the malware runs in the memory, the memory acquisition becomes useless once the system gets reboot
Apple's own Encryption Mechanism allows hacker to create an Undetectable Mac OS X Malware

Apple's own Encryption Mechanism allows hacker to create an Undetectable Mac OS X Malware

October 07, 2013Mohit Kumar
In the past, there was a general belief that Macs is much more secure than Windows PCs, but now Mac malware is a serious threat to the security of users' computers and information. One of the reasons behind the increase in Mac related Malware attacks is the fact that Apple products are popular with many prominent businessmen and influential politicians. Daniel Pistelli, Reverse Engineer and lead developer of Cerbero Profiler, former developer of IDA Pro comes up with another interesting research, and explained The Hacker News , the basic details behind the technique he used to create an undetectable malware for Mac OS X. Apple implements internally an encryption mechanism to protect some of their own executable like " Dock.app " or " Finder.app ". This encryption can be applied to malware as well. If one does, anti-malware solutions can no longer detect the malware because of the encryption, but OS X has no problem loading such malware. This same
Shylock malware : Undetectable virus stealing bank account information

Shylock malware : Undetectable virus stealing bank account information

December 01, 2012Mohit Kumar
Shylock, a financial malware platform discovered by Trusteer in 2011, is a non-Zeus-based information-stealing trojan that improved methodology for injecting code into additional browser processes to take control of a computer, and an improved evasion technique to prevent malware scanners from detecting its presence. Why this Name ?  Shylock named after the ruthless money lender in Shakespeare's The Merchant of Venice, also deletes its installation files, runs solely in memory, and begins the process again once the infected machine reboots. Shylock has gained a new trick: The ability to detect whether it's running in a virtual machine (VM) that is being analyzed by malware researchers. What New ?  Latest Shylock dropper detects a remote desktop environment by feeding invalid data into a certain routine and then observing the error code returned. It uses this return code to differentiate between normal desktops and other "lab" environments. In particular, when execu
