Someone Hijacks Botnet Network & Replaces Malware with an Antivirus
Feb 05, 2016
The Dridex banking trojan that is widely being used by cyber criminals to distribute malware onto users' machines has now been found distributing a security software. A portion of the Dridex banking Trojan botnet may have been hacked or compromised by an unknown Whitehat Hacker, who replaced the malicious links with  Avira Antivirus  installers. What is Dridex Banking Trojan? How it Works? Dridex malware – also known as Bugat and Cridex – is believed to have been created by cyber criminals in Eastern Europe in an effort to harvest online banking details. Even after a high-profile takedown operation in late 2015, the Dridex botnet seems to be active again. The Dridex virus typically distributes itself through spam messages or emails that include malicious attachments, most often a Microsoft Office file or Word document integrated with malicious macros. Once the malicious file has been clicked, the macros download and install the main payload of the virus – th

CryptoLocker Ransomware demands $300 or Two Bitcoins to decrypt your files
Oct 13, 2013
If you're a daily computer user, you're likely aware of all the threats you face every day online in the form of viruses and malware . CryptoLocker , a new ransomware malware, began making the rounds several months ago. This ransomware is particularly nasty because infected users are in danger of losing their personal files forever. Ransomware is designed to extort money from computer users by holding computer files hostage until the computer user pays a ransom fee to get them back. The Cryptolocker hijacker sniffs out your personal files and wraps them with strong encryption before it demands money. Cryptolocker is spread through malicious hyperlinks shared via social media and spam emails, like fake UPS tracking notification emails. The original demanded payments of $100 to decrypt files, but the new and improved version demanding $300 from victims. Apparently, the encryption is created using a unique RSA-2048 public key. The decryption key is located o

FixMeStick's first to supports Windows 8 with Secure Boot ON

FixMeStick's first to supports Windows 8 with Secure Boot ON
Jun 12, 2013
Windows 8 PCs contain a new technology called Secure Boot that only boots devices that have been verified by Microsoft. Also Microsoft's own Offline Defender won't boot on Windows 8 PCs with Secure Boot on. Neither will Norton's Bootable Recovery Tool. We asked the guys at FixMeStick how their external hardware-based anti-malware device can boot on brand new Windows 8 hardware with Secure boot on, as well as 10 year old PCs with 32 processors running XP. Here's their answer: 1. It got a Master Boot Record. : In other words, it boots on BIOS-based PCs, essentially all PCs prior to Windows 8. 2. and it got UEFI boot partition : It also got a UEFI boot partition, so it will boot on PCs with the latest UEFI firmware too. 3. It's 32 bit : There's a 32 bit operating system on the stick so it will work with 32 bit microprocessors. Most rescue ISOs\disks are 32 bit only, so by default they work on 32 bit processors and 64 bit processors. 4. and it's 64

Feb 03, 2013
A new Cyber Crimeware kit arrived in Hacking scenes called 'PiceBOT' just like other Latin American botnets such as vOlk (Mexico) & S.A.P.Z (Peru) and  cost just $140 in underground market for Cyber criminals. Like other amazing exploit kits, the main purpose is the distribution of malware that steals financial information through local pharming attacks. Bad bots perform malicious tasks allowing an attacker to take complete control over an affected computer for the criminal to control remotely. Once infected, these machines may also be referred to as 'zombies'. Kaspersky uncovered that this kit has already been adopted by Latin American cyber criminals to target clients of major banks and so far financial bodies from Chile, Peru, Panama, Costa Rica, Mexico, Colombia, Uruguay, Venezuela, Ecuador, Nicaragua and Argentina under attack. Detected as  Trojan-Dropper.Win32.Injector , the malware having couple of dozen variants. Malware is still under observation by an

Dissecting a mobile malware
Jan 27, 2013
The capillary diffusion of mobile devices, the lack of security systems on these platforms and low level of awareness on principal cyber threats made them a privileged target for cybercrime. We have assisted in the recent year to an explosion of malware designed to hit principal mobile OSs, in a recent report Sophos security firm revealed that in Australia and the U.S. Android threat exposure rates exceeding those of PCs showing the urgency to implement proper countermeasures. The situation appears really critical that why I asked to the expert of Group-IB Forensics Lab to show me how these agents work with a really case study. Several month ago Group-IB Forensics Lab detected mobile-banking malware through Google Play by Sberbank request (Russian leading national bank).  The File associated to the malware was named sber.apk , it was an Android Package having size of 225,905 bytes and digest md5: F27D43DFEEDFFAC2EC7E4A069B3C9516 .

Universal Man in the Browser Attacks

Universal Man in the Browser Attacks
Oct 03, 2012
Researchers have discovered a new type of Man-in-the-Browser (MItB) attack that is Website independent, and does not target specific Websites, but instead collects data submitted to all sites. Trusteer have discovered a new Man in the Browser (MitB) scam that can collects data submitted to all websites without the need for post-processing. According to Trusteer's CTO Amit Klein: " In comparison, uMitB does not target a specific web site. Instead, it collects data entered in the browser at all websites and uses "generic" real time logic on the form submissions to perform the equivalent of post-processing. This attack can target victims of new infections as well as machines that were previously infected by updating the existing malware with a new configuration. The data stolen by uMitB malware is stored in a portal where it is organized and sold ." In a YouTube video, the company demonstrated how the attack could happen. The video showed how a user could enter personal a

Oct 03, 2012
Blue Coat systems has undertaken detailed research into the use of 'malnets' by criminals to help support their various attacks in order to uncover the best ways to take down these systems. Botnet infections are commonly spread though compromised websites seeded with malicious scripts and promoted via black hat SEO tactics such as link farms. These malware networks, or malnets, pose a growing threat, The company said the number of malnets now stands at more than 1,500, an increase of 300% in the past six months, and it expects they will be, "responsible for two-thirds of all malicious cyberattacks in 2012." According to Blue Coat, the largest known malnet is Shnakule, which has used up to 5,005 malicious hosts or servers at any given time, depending on the capabilities needed at any given moment by its operators. Blue Coat believes that Shnakule is controlled by a single gang, and it's been used to serve up just about every type of known attack, including &quo

Oct 02, 2012
More than 4.5 million DSL modems have been compromised as part of a sustained hacking campaign in Brazil, with the devices spreading malware and malicious web address redirects. According to the malware analyst at Kaspersky Lab in Brazil, Fabio Assolini. The vulnerability exploited by attackers allowed the use of a script to steal passwords and remotely access the configuration of modems. The attacks was described as " One firmware vulnerability, two malicious scripts, three hardware manufacturers, 35 malicious DNS servers, thousands of compromised ADSL modems, millions of victims. " According to Kaspersky, the Brazilian attackers sought to steal users' banking credentials by redirecting users to false versions of popular sites like Facebook or Google and prompting them to install malware. Some 40 DNS servers were set up outside Brazil too in order to serve forged requests for domain names belonging to Brazilian banks. Nakedsecurity writes,-- The first thing users ma

ARMY : USB Drive responsible for over 70 percent of Cyber Security Breaches
Sep 30, 2012
A ban on the use of pen drives has not been able to safeguard cyber security as it has now been labeled as a major threat in defence forces, the Army officials said. The use of pen drives as an easy-to-carry storage device has increased in the recent past and internal reports have confirmed that over 70 percent cyber security breaches in the armed forces are due to their unauthorised use " These pen drives, which are mostly manufactured in China, have emerged as a big threat to our cyber security systems ," they said. Generally it is found that officials use pen drive to store official data for use at their personal computers but from there, it is transmitted from their IP addresses to hackers from the 'malware' present in the pen drives. About a couple of years ago, a Major posted in Andaman and Nicobar Islands was apprehended as it was found that sensitive data was being transferred from his computer.  However, it later emerged that his system had been hacked and

It's a fact that as smartphones get more capable, the possibilities for their misuse also increase. They're already exploited by crooks to swipe personal information, but a new Android app created by the U.S. Navy is on another level entirely. It's a scary piece of malware called " PlaceRaider " that was developed by the US Naval Surface Warfare center and for now it is being viewed as just a proof of concept. According to the MIT Technology Review, researchers at Indiana University and the Naval Surface Warfare Center have developed a new form of malware designed to record and reconstruct a victim's environment. They has just worked out how to infect a mobile phone with a Trojan that can take photos without you knowing anything about it and send sensor data back to a server. The data are used to construct a 3D model which can be used not only to perform the reconnaissance necessary to break in, but also to steal confidential information such as bank details. O

New Android Exploit Could Force Factory Reset remotely

New Android Exploit Could Force Factory Reset remotely
Sep 25, 2012
Clicking one wrong link can cause malicious code to execute, which could do anything from infecting your computer with malware to, apparently, wiping your phone data completely. At the Ekoparty security conference, researcher Ravi Borganokar demonstrated at the Ekoparty security conference in Argentina last week, that how a single line of HTML code could be used to run a factory reset or even clear the SIM card on certain Samsung phones. Malicious hackers can hide a code in a web page that will trigger a full factory reset of Samsung's best-selling Galaxy S3 smartphone, deleting contacts, photographs, music, apps and other valuable data. The devastating flaw lies in Samsung's dialling software, triggered by the tel protocol in a URL. It isn't applicable to all the company's Android handsets, but those that are vulnerable can have their PIN changed or be wiped completely just by visiting a web page or snapping a bad QR code, or even bonking up against the wrong wireless N

Exploit Released for Internet Explorer zero-day attacks : CVE-2012-4969
Sep 19, 2012
Microsoft has confirmed reports that a zero-day vulnerability in its Internet Explorer browser is being actively attacked in the wild. Four active exploits of a zero-day vulnerability in the browser exists. Microsoft will push out an out-of-cycle Windows patch to temporarily fix the critical Internet Explorer flaw. Security researcher Eric Romang identified the exploit code on a server used by the "Nitro" hacking group, believed to have exploited the Java zero-day vulnerability reported last month.  Security firm Rapid7 advises that Internet users try a different Web browser. The malware may be linked to an ongoing attack on companies that has been dubbed "Nitro", and was first discovered in October by Symantec. The zero-day in IE 6-9 is a use-after-free memory corruption vulnerability , similar to a buffer overflow, that would enable an attacker to remotely execute code on a compromised machine. The original exploit payload dropped the PoisonIvy remote access Trojan (RAT)

Android 4.0.4 multiple Zero-Day Vulnerabilities
Sep 19, 2012
The Samsung Galaxy S3 can be hacked via NFC, allowing attackers to download all data from the Android smartphone, security researchers demonstrated during the Mobile Pwn2Own contest in Amsterdam. Using a pair of zero day vulnerabilities, a team of security researchers from U.K.-based MWR Labs hacked into a Samsung Galaxy S3 phone running Android 4.0.4 by beaming an exploit via NFC (Near Field Communications). NFC is a technology that allows data to be sent over very short distances. For mobile devices, the protocol allows digital wallet applications to transfer money to pay at the register. While the technology has been slow to take off, despite the adoption by Google for its Wallet payment application, a number of recent high-profile announcements have boosted its adoption. " Through NFC it was possible to upload a malicious file to the device, which allowed us to gain code execution on the device and subsequently get full control over the device using a second vulnerability
