May 19, 2014Wang Wei
If you are dealing in cryptocurrency Bitcoin and have Microsoft's Security Essentials (MSE) installed on your system, then you could be infected by a virus called " DOS/STONED " from the Bitcoin BlockChain. With a number of high-profile cases of fraud, theft, and technical incompetence against the bitcoins, it seems like cyber criminals are looking to scam unsuspecting customers. Blockchain is Bitcoin's most popular bitcoin wallet and block explorer. It is a central part of the Bitcoin system that includes a log file in which all bitcoin transactions are recorded. It stores the wallet data in encrypted form and runs on privately owned dedicated hardware. In an discussion on the Microsoft discussion boards, a user go by the name ' edc678 ' claimed that  Microsoft's Security Essentials  is showing alerts of the signature of the STONED virus in the Bitcoin BlockChain, which could only allow an attacker to write small chunk of text to accomp

Chameleon Virus that Spreads Across WiFi Access Points like Common Cold

February 26, 2014Anonymous
Do you know, A Computer viruses could go Airborne over WiFi networks? Security researchers at the University of Liverpool  in Britain have demonstrated a WiFi virus that can spread between computer networks just like the ' common cold ' spreads between Humans. They have created a proof-of-concept which can infect the entire wireless network instead of a single computer at a time,  that replaces the firmware of the vulnerable Access Point (AP) with a virus-loaded version, and then propagates itself to the next victim on the WiFi network . The  WiFi  based virus named as ' Chameleon ', that can self-propagate over WiFi networks from access point to access point,  but  doesn't affect the working of the Wireless Access Point. This Virus is able to identify WiFi access points that are not protected by encryption and passwords, according to the research paper . It can badly hit less-protected open access WiFi networks available in coffee shops or airp

Zeus , a financially aimed Banking Trojan that comes in many different forms and flavors, is capable to steal users' online-banking credentials once installed. This time, an infamous  Zeus Trojan has turned out to be a more sophisticated piece of malware that uses web-crawling action . Instead of going after Banking credentials and performing malicious keystroke logging, a new variant of Zeus Trojan focuses on Software-as-a-service (SaaS) applications for the purpose of obtaining access to proprietary data or code. The SaaS Security firm vendor Adallom , detected a targeted malware attack campaign against a Salesforce.com customer, which began as an attack on an employee's home computer. Adallom found that the new variant had web crawling capabilities that were used to grab sensitive business data from that customer's CRM instance.

Gameover Malware, variant of ZeuS Trojan uses Encryption to Bypass Detection

February 04, 2014Swati Khandelwal
The year begins with the number of new variants of malware that were discovered by various security researchers. The new variants are more complex, sophisticated and mostly undetectable. Two years back in 2012, the FBI warned us about the ‘ GameOver ’ banking Trojan, a variant of Zeus financial malware that spreads via phishing emails. GameOver makes fraudulent transactions from your bank once installed in your system with the capability to conduct Distributed Denial of Service, or DDoS, attack using a botnet, which involves multiple computers flooding the financial institution’s server with traffic in an effort to deny legitimate users access to the site. But that wasn't the end; a new variant of the same family of banking Trojan has been discovered by researchers that are being delivered by cyber criminals to users’ machines, making it easier for the banking malware to evade detection and steal victim’s banking credentials.

Hollywood wants Right to use Malware to hack the computers of Pirates

May 28, 2013Mohit Kumar
In the constant battle between illegal file sharers (Pirates) and the entertainment industry (Hollywood) supplying the protected digital materials, the pirates have been staying one step ahead, although the industry may soon have a powerful new weapon in their arsenal. A new report released by the Commission on the Theft of American Intellectual Property suggests the use of malware to fight piracy. In a report, the Commission on the Theft of American Intellectual Property proposed many ways piracy can be combated, including infecting alleged violators’ computers with malware that can wreck havoc, including and up to destroying the user’s computer. It would also give the entertainment industry the advantage of tracking those who commit IP theft on-line no matter their location. Though it sounds reasonable on the surface, it is really a bad idea due to the challenge of correctly identifying a cyber attacker, as well as the unavoidable risk of collateral damage.

April 27, 2013Mohit Kumar
A new sophisticated and stealthy Apache backdoor meant to drive traffic to malicious websites serving Blackhole exploit kit widely has been detected by  Sucuri recently. Researchers claimed that this backdoor affecting hundreds of web servers right now. Dubbed Linux/Cdorked.A , one of the most sophisticated Apache backdoors we have seen so far. The backdoor leaves no traces of compromised hosts on the hard drive other than its modified httpd binary, thereby complicating forensics analysis. All of the information related to the backdoor is stored in shared memory.  The configuration is pushed by the attacker through obfuscated HTTP requests that aren't logged in normal Apache logs. The HTTP server is equipped with a reverse connect backdoor that can be triggered via a special HTTP GET request. This means that no command and control information is stored anywhere on the system. ESET researchers  analyzed the binary and discovered a nasty hidden backdoor. In the Li

November 27, 2012Mohit Kumar
Symantec recently identified a database-corrupting piece of malware targeting systems mostly in Iran, but despite early speculation that it could be related to the likes of Stuxnet and Flame, it appears to be targeting small businesses rather than the country’s infrastructure. Malware Dubbed W32.Narilam , is predominantly active in the Middle East, and it has also been detected in the USA and UK. The worm looks for particular words in Microsoft SQL databases and overwrites them. The worm specifically targets SQL databases with three distinct names, alim, maliran, and shahd. Once the targeted databases are found, Narilam looks for specific objects and tables and either deletes the tables or replaces items with random values. On Monday an alert was published on tarrahsystem.com warning of the W32.Narilam threat to its customers. The bulk of the infections thus far have been found in the Middle East, particularly Iran and Afghanistan.
