WARNING: Hackers Install Secret Backdoor on Thousands of Microsoft SQL Servers

WARNING: Hackers Install Secret Backdoor on Thousands of Microsoft SQL Servers

April 01, 2020Ravie Lakshmanan
Cybersecurity researchers today uncovered a sustained malicious campaign dating back to May 2018 that targets Windows machines running MS-SQL servers to deploy backdoors and other kinds of malware, including multi-functional remote access tools (RATs) and cryptominers. Named " Vollgar " after the Vollar cryptocurrency it mines and its offensive "vulgar" modus operandi, researchers at Guardicore Labs said the attack employs password brute-force to breach Microsoft SQL servers with weak credentials exposed to the Internet. Researchers claim the attackers managed to successfully infect nearly 2,000-3,000 database servers daily over the past few weeks, with potential victims belonging to healthcare, aviation, IT & telecommunications, and higher education sectors across China, India, the US, South Korea, and Turkey. Thankfully for those concerned, researchers have also released a script to let sysadmins detect if any of their Windows MS-SQL servers have been

Multiple DDoS Botnets Exploited 0-Day Flaws in LILIN DVR Surveillance Systems

March 21, 2020Ravie Lakshmanan
Multiple zero-day vulnerabilities in digital video recorders (DVRs) for surveillance systems manufactured by Taiwan-based LILIN have been exploited by botnet operators to infect and co-opt vulnerable devices into a family of denial-of-service bots. The findings come from Chinese security firm Qihoo 360 's Netlab team, who say different attack groups have been using LILIN DVR zero-day vulnerabilities to spread Chalubo , FBot , and Moobot botnets at least since August 30, 2019. Netlab researchers said they reached out to LILIN on January 19, 2020, although it wasn't until a month later the vendor released a firmware update (2.0b60_20200207) addressing the vulnerabilities. The development comes as IoT devices are increasingly being used as an attack surface to launch DDoS attacks and as proxies to engage in various forms of cybercrime. What Are the LILIN Zero-Days About? The flaw in itself concerns a chain of vulnerabilities that make use of hard-coded login cred

Mukashi: A New Mirai IoT Botnet Variant Targeting Zyxel NAS Devices

March 21, 2020Ravie Lakshmanan
A new version of the infamous Mirai botnet is exploiting a recently uncovered critical vulnerability in network-attached storage (NAS) devices in an attempt to remotely infect and control vulnerable machines. Called " Mukashi ," the new variant of the malware employs brute-force attacks using different combinations of default credentials to log into Zyxel NAS, UTM, ATP, and VPN firewall products to take control of the devices and add them to a network of infected bots that can be used to carry out Distributed Denial of Service (DDoS) attacks. Multiple Zyxel NAS products running firmware versions up to 5.21 are vulnerable to the compromise, Palo Alto Networks' Unit 42 global threat intelligence team said, adding they uncovered the first such exploitation of the flaw in the wild on March 12. Zyxel's Pre-Authentication Command Injection Flaw Mukashi hinges on a pre-authentication command injection vulnerability (tracked as CVE-2020-9054 ), for which a proof-

Cybercriminals will stop at nothing to exploit every chance to prey on internet users. Even the disastrous spread of SARS-COV-II (the virus), which causes COVID-19 (the disease), is becoming an opportunity for them to likewise spread malware or launch cyber attacks. Reason Cybersecurity recently released a threat analysis report detailing a new attack that takes advantage of internet users' increased craving for information about the novel coronavirus that is wreaking havoc worldwide. The malware attack specifically aims to target those who are looking for cartographic presentations of the spread of COVID-19 on the Internet, and trickes them to download and run a malicious application that, on its front-end, shows a map loaded from a legit online source but in the background compromises the computer. New Threat With An Old Malware Component The latest threat, designed to steal information from unwitting victims, was first spotted by MalwareHunterTeam last week and h

US Govt Warns Critical Industries After Ransomware Hits Gas Pipeline Facility

February 19, 2020Ravie Lakshmanan
The U.S. Department of Homeland Security's Cybersecurity and Infrastructure Security Agency (CISA) earlier today issued a warning to all industries operating critical infrastructures about a new ransomware threat that if left unaddressed could have severe consequences. The advisory comes in response to a cyberattack targeting an unnamed natural gas compression facility that employed spear-phishing to deliver ransomware to the company's internal network, encrypting critical data and knocking servers out of operation for almost two days. "A cyber threat actor used a spear-phishing link to obtain initial access to the organization's information technology network before pivoting to its operational technology network. The threat actor then deployed commodity ransomware to encrypt data for impact on both networks," CISA noted in its alert. As ransomware attacks continue to escalate in frequency and scale , the new development is yet another indication that p

A new report published by cybersecurity researchers has unveiled evidence of Iranian state-sponsored hackers targeting dozens of companies and organizations in Israel and around the world over the past three years. Dubbed " Fox Kitten ," the cyber-espionage campaign is said to have been directed at companies from the IT, telecommunication, oil and gas, aviation, government, and security sectors. "We estimate the campaign revealed in this report to be among Iran's most continuous and comprehensive campaigns revealed until now," ClearSky researchers said . "The revealed campaign was used as a reconnaissance infrastructure; however, it can also be used as a platform for spreading and activating destructive malware such as ZeroCleare and Dustman." Tying the activities to threat groups APT33, APT34, and APT39, the offensive — conducted using a mix of open source and self-developed tools — also facilitated the groups to steal sensitive information
Emotet Malware Now Hacks Nearby Wi-Fi Networks to Infect New Victims

Emotet Malware Now Hacks Nearby Wi-Fi Networks to Infect New Victims

February 12, 2020Ravie Lakshmanan
Emotet, the notorious trojan behind a number of botnet-driven spam campaigns and ransomware attacks, has found a new attack vector: using already infected devices to identify new victims that are connected to nearby Wi-Fi networks. According to researchers at Binary Defense , the newly discovered Emotet sample leverages a "Wi-Fi spreader" module to scan Wi-Fi networks, and then attempts to infect devices that are connected to them. The cybersecurity firm said the Wi-Fi spreader has a timestamp of April 16, 2018, indicating the spreading behavior has been running "unnoticed" for close to two years until it was detected for the first time last month. The development marks an escalation of Emotet's capabilities, as networks in close physical proximity to the original victim are now susceptible to infection. How Does Emotet's Wi-Fi Spreader Module Work? The updated version of the malware works by leveraging an already compromised host to list all
Landry's Restaurant Chain Suffers Payment Card Theft Via PoS Malware

Landry's Restaurant Chain Suffers Payment Card Theft Via PoS Malware

January 02, 2020Mohit Kumar
Landry's, a popular restaurant chain in the United States, has announced a malware attack on its point of sale (POS) systems that allowed cybercriminals to steal customers' payment card information. Landry's owns and operates more than 600 bars, restaurants, hotels, casinos, food and beverage outlets with over 60 different brands such as Landry's Seafood, Chart House, Saltgrass Steak House, Claim Jumper, Morton's The Steakhouse, Mastro's Restaurants, and Rainforest Cafe. According to the  breach notification published this week, the malware was designed to search for and likely steal sensitive customer credit card data, including credit card numbers, expiration dates, verification codes and, in some cases, cardholder names. The PoS malware infected point-of-sale terminals at all Landry's owned locations, but, fortunately, due to end-to-end encryption technology used by the company, attackers failed to steal payment card data from cards swiped at its
New Zeppelin Ransomware Targeting Tech and Health Companies

New Zeppelin Ransomware Targeting Tech and Health Companies

December 11, 2019Mohit Kumar
A new variant of Vega ransomware family, dubbed Zeppelin , has recently been spotted in the wild targeting technology and healthcare companies across Europe, the United States, and Canada. However, if you reside in Russia or some other ex-USSR countries like Ukraine, Belorussia, and Kazakhstan, breathe a sigh of relief, as the ransomware terminates its operations if found itself on machines located in these regions. It's notable and interesting because all previous variants of the Vega family, also known as VegaLocker, were primarily targeting Russian speaking users, which indicates Zeppelin is not the work of the same hacking group behind the previous attacks. Since Vega ransomware and its previous variants were offered as a service on underground forums, researchers at BlackBerry Cylance believes either Zeppelin "ended up in the hands of different threat actors" or "redeveloped from bought/stolen/leaked sources." According to a report BlackBerry Cyl

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
Apple iTunes and iCloud for Windows 0-Day Exploited in Ransomware Attacks

Apple iTunes and iCloud for Windows 0-Day Exploited in Ransomware Attacks

October 10, 2019Mohit Kumar
Watch out Windows users! The cybercriminal group behind BitPaymer and iEncrypt ransomware attacks has been found exploiting a zero-day vulnerability affecting a little-known component that comes bundled with Apple's iTunes and iCloud software for Windows to evade antivirus detection. The vulnerable component in question is the Bonjour updater, a zero-configuration implementation of network communication protocol that works silently in the background and automates various low-level network tasks, including automatically download the future updates for Apple software. To be noted, since the Bonjour updater gets installed as a separate program on the system, uninstalling iTunes and iCloud doesn't remove Bonjour, which is why it eventually left installed on many Windows computers — un-updated and silently running in the background. Cybersecurity researchers from Morphisec Labs discovered the exploitation of the Bonjour zero-day vulnerability in August when the attackers
