According to a new report, the world's biggest personal computer maker, Chinese firm Lenovo Group Limited has reportedly been banned from supplying equipment for  networks of the intelligence and defense services of Australia, the United States, Britain, Canada and New Zealand, due to hacking concerns. Sources from intelligence and defense entities in the UK and Australia have confirmed the ban introduced in the mid-2000s after intensive laboratory testing of its equipment. In 2006 it was disclosed that the US State Department had decided not to use 16,000 new Lenovo computers on classified networks because of security concerns. Serious backdoor vulnerabilities in hardware and firmware were apparently discovered during the tests which could allow attackers to remotely access devices without the knowledge of the owner. Lenovo, headquartered in Beijing, acquired IBM's personal computer business in 2005, after which IBM continued to sell servers and mainframes that we

" Ransomware " may be a term you haven't heard before. This type of criminal malware, which spread around the world on PCs in 2012, encrypts some or all the files on a computer and holds them for ransom and  Cyber thieves have already made millions through such methods. Ransomware is no longer all about computers. It has evolved to now target mobile devices, specifically Androids platform. For a hacker, a pop up message is just one more way to steal money by sending fake alerts and serious warnings that scare a user into making a payment. For example, in the case of PCs, we have encountered malware that encrypts crucial data on a user's hard disk, asking the victim to pay a sum to the attacker in order to recover his/her data. Last year in November at many Hacking Conferences, Security Researcher Mohit Kumar ( @Unix_Root ) already demonstrated one the most sophisticated android malware called " Android Malware Engine ", one of its kind yet

Identities now transcend human boundaries. Within each line of code and every API call lies a non-human identity. These entities act as programmatic access keys, enabling authentication and facilitating interactions among systems and services, which are essential for every API call, database query, or storage account access. As we depend on multi-factor authentication and passwords to safeguard human identities, a pressing question arises: How do we guarantee the security and integrity of these non-human counterparts? How do we authenticate, authorize, and regulate access for entities devoid of life but crucial for the functioning of critical systems? Let's break it down. The challenge Imagine a cloud-native application as a bustling metropolis of tiny neighborhoods known as microservices, all neatly packed into containers. These microservices function akin to diligent worker bees, each diligently performing its designated task, be it processing data, verifying credentials, or

Trend Micro researchers have uncovered a new backdoor pieces of malware from the Winnti family, which are mainly used by a Chinese  cyber criminal group to target South East Asian organizations from the video gaming sector. Winnti malware used by hackers to hijack control of web users systems using a new backdoor contained in the legitimate Aheadlib analysis tool. Dubbed as " Bkdr_Tengo.A, " passes itself off as a legitimate system DLL file called winmm.dll. " We believe that this was done using a legitimate tool called Aheadlib, which is a legitimate analysis tool. "  wrote Trend Micro's Eduardo Altares. " The file is not encrypted and neither was it particularly hard to analyze. Its main behavior is to steal Microsoft Office, .PDF, and .TIFF files from USB drives inserted into the system. These stolen files are stored in the $NtUninstallKB080515$ under the Windows folder. It also creates a log file named Usblog_DXM.log. The files can be retrieved by

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

A new malware threat for the Mac has been discovered that attempting to set up a secure connection for a remote hacker to connect through and grab private information. Dubbed " Pintsized " that uses a modified version of OpenSSH to potentially set up a remote connection into Mac accounts. This backdoor Trojan can be used to conduct distributed denial of service (DDoS) attacks, or it can be used to install additional Trojans or other forms of malicious software. Since the connection between the hacker and the machine is encrypted, it becomes very hard for the Trojan to be detected or traced. The threat has the potential to become serious, as it uses an exploit in OS X to bypass Gatekeeper and establish a reverse shell that creates a secure connection.  Trojan stays hidden by disguising itself as a file that is used for networked printers in Mac OS X. The location of the malware has been traced to this particular directory. This tactic conceals the Trojan and makes a moni

Incapsula announced this week that they're offering an intriguing Backdoor Protection feature for sites using their cloud-based website security and performance services. What's a Backdoor? A backdoor is a malicious function that enables hackers to remotely operate a site or server, even after whatever exploit they used for initial access has been patched. Installing a backdoor is often the first thing a hacker will do after gaining access to your site - so if you've been hacked before, there's a good chance you've already got one. Hackers love backdoors because they provide easy return access to the site. Once installed, backdoors can used to distribute spam and malware, launch distributed denial of service (DDoS) attacks, or to help steal valuable data like credit card numbers. Recently, Incapsula reported how during the ongoing DDoS attacks against United States banks, a backdoor was used to turn a compromised site into a unwilling foot-soldier in the hackers Zombie Bo
