Targeted Ransomware Attacks Hit Several Spanish Companies

Targeted Ransomware Attacks Hit Several Spanish Companies

Nov 04, 2019
Everis , one of the largest IT consulting companies in Spain, suffered a targeted ransomware attack on Monday, forcing the company to shut down all its computer systems until the issue gets resolved completely. Ransomware is a computer virus that encrypts files on an infected system until a ransom is paid. According to several local media, Everis informed its employees about the devastating widespread ransomware attack, saying: "We are suffering a massive virus attack on the Everis network. Please keep the PCs off. The network has been disconnected with clients and between offices. We will keep you updated." "Please, urgently transfer the message directly to your teams and colleagues due to standard communication problems." According to cybersecurity consultant  Arnau Estebanell Castellví , the malware encrypted files on Everis's computers with an extension name resembling the company's name, i.e., " .3v3r1s ," which suggests the at...
Watch Out IT Admins! Two Unpatched Critical RCE Flaws Disclosed in rConfig

Watch Out IT Admins! Two Unpatched Critical RCE Flaws Disclosed in rConfig

Nov 03, 2019
If you're using the popular rConfig network configuration management utility to protect and manage your network devices, here we have an important and urgent warning for you. A cybersecurity researcher has recently published details and proof-of-concept exploits for two unpatched, critical remote code execution vulnerabilities in the rConfig utility, at least one of which could allow unauthenticated remote attackers to compromise targeted servers, and connected network devices. Written in native PHP, rConfig is a free, open source network device configuration management utility that allows network engineers to configure and take frequent configuration snapshots of their network devices. According to the project website, rConfig is being used to manage more than 3.3 million network devices, including switches, routers, firewalls, load-balancer, WAN optimizers. What's more worrisome? Both vulnerabilities affect all versions of rConfig, including the latest rConfig ver...
First Cyber Attack 'Mass Exploiting' BlueKeep RDP Flaw Spotted in the Wild

First Cyber Attack 'Mass Exploiting' BlueKeep RDP Flaw Spotted in the Wild

Nov 03, 2019
Cybersecurity researchers have spotted a new cyberattack that is believed to be the very first but an amateur attempt to weaponize the infamous BlueKeep RDP vulnerability in the wild to mass compromise vulnerable systems for cryptocurrency mining. In May this year, Microsoft released a patch for a highly-critical remote code execution flaw, dubbed  BlueKeep , in its Windows Remote Desktop Services that could be exploited remotely to take full control over vulnerable systems just by sending specially crafted requests over RDP. BlueKeep, tracked as CVE-2019-0708 , is a wormable vulnerability because it can be weaponized by potential malware to propagate itself from one vulnerable computer to another automatically without requiring victims' interaction. BlueKeep has been considered to be such a serious threat that since its discovery, Microsoft and even government agencies [ NSA and GCHQ ] had continuously been encouraging Windows users and admins to apply security p...

New Chrome 0-day Bug Under Active Attacks – Update Your Browser Now!

Nov 01, 2019
Attention readers, if you are using Chrome on your Windows, Mac, and Linux computers, you need to update your web browsing software immediately to the latest version Google released earlier today. With the release of Chrome 78.0.3904.87, Google is warning billions of users to install an urgent software update immediately to patch two high severity vulnerabilities, one of which attackers are actively exploiting in the wild to hijack computers. Without revealing technical details of the vulnerability, the Chrome security team only says that both issues are use-after-free vulnerabilities, one affecting Chrome's audio component ( CVE-2019-13720 ) while the other resides in the PDFium ( CVE-2019-13721 ) library. The use-after-free vulnerability is a class of memory corruption issues that allows corruption or modification of data in the memory, enabling an unprivileged user to escalate privileges on an affected system or software. Thus, both flaws could enable remote attackers...
Chinese Hackers Compromise Telecom Servers to Spy on SMS Messages

Chinese Hackers Compromise Telecom Servers to Spy on SMS Messages

Oct 31, 2019
A group of Chinese hackers carrying out political espionage for Beijing has been found targeting telecommunications companies with a new piece of malware designed to spy on text messages sent or received by highly targeted individuals. Dubbed " MessageTap ," the backdoor malware is a 64-bit ELF data miner that has recently been discovered installed on a Linux-based Short Message Service Center (SMSC) server of an unnamed telecommunications company. According to a recent report published by FireEye's Mandiant firm, MessageTap has been created and used by APT41 , a prolific Chinese hacking group that carries out state-sponsored espionage operations and has also been found involved in financially motivated attacks. In mobile telephone networks, SMSC servers act as a middle-man service responsible for handling the SMS operations by routing messages between senders and recipients. Since SMSes are not designed to be encrypted, neither on transmitting nor on the telec...
