The United States agencies today released a joint advisory warning the world about the 'significant cyber threat' posed by North Korean state-sponsored hackers to the global banking and financial institutions. Besides a summary of recent cyberattacks attributed to North Korean hackers, the advisory—issued by U.S. Departments of State, the Treasury, and Homeland Security, and the FBI—also contains a comprehensive guide intends to help the international community, industries, and other governments defend against North Korea's illicit activities. "In particular, the United States is deeply concerned about North Korea's malicious cyber activities, which the U.S. government refers to as HIDDEN COBRA. The DPRK has the capability to conduct disruptive or destructive cyber activities affecting U.S. critical infrastructure," the advisory says . "The DPRK also uses cyber capabilities to steal from financial institutions, and has demonstrated a pattern of d

Computer manufacturing giant Dell has released a new security tool for its commercial customers that aims to protect their computers from stealthy and sophisticated cyberattacks involving the compromise of the BIOS. Dubbed ' SafeBIOS Events & Indicators of Attack ' (IoA), the new endpoint security software is a behavior-based threat detection system that alerts users when BIOS settings of their computers undergo some unusual changes. BIOS (Basic Input Output System) is a small but highly-privileged program that handles critical operations and starts your computer before handing it over to your operating system. Protecting the BIOS program is crucial because: Changes to the system BIOS settings could allow malicious software to run during the boot process, Once a hacker takes over the BIOS, he can stealthily control the targeted computer and gain access to the data stored on it, Malware in BIOS remains persistent and doesn't get away even when you format or

The introduction of Open AI's ChatGPT was a defining moment for the software industry, touching off a GenAI race with its November 2022 release. SaaS vendors are now rushing to upgrade tools with enhanced productivity capabilities that are driven by generative AI. Among a wide range of uses, GenAI tools make it easier for developers to build software, assist sales teams in mundane email writing, help marketers produce unique content at low cost, and enable teams and creatives to brainstorm new ideas.  Recent significant GenAI product launches include Microsoft 365 Copilot, GitHub Copilot, and Salesforce Einstein GPT. Notably, these GenAI tools from leading SaaS providers are paid enhancements, a clear sign that no SaaS provider will want to miss out on cashing in on the GenAI transformation. Google will soon launch its SGE "Search Generative Experience" platform for premium AI-generated summaries rather than a list of websites.  At this pace, it's just a matter of a short time befo

As hospitals around the world are struggling to respond to the coronavirus crisis, cybercriminals—with no conscience and empathy—are continuously targeting healthcare organizations, research facilities, and other governmental organizations with ransomware and malicious information stealers. The new research, published by Palo Alto Networks and shared with The Hacker News, confirmed that "the threat actors who profit from cybercrime will go to any extent, including targeting organizations that are in the front lines and responding to the pandemic on a daily basis." While the security firm didn't name the latest victims, it said a Canadian government healthcare organization and a Canadian medical research university both suffered ransomware attacks, as criminal groups seek to exploit the crisis for financial gain. The attacks were detected between March 24 and March 26 and were initiated as part of the coronavirus-themed phishing campaigns that have become widespr

Cybersecurity researchers have discovered a new emerging IoT botnet threat that leverages compromised smart devices to stage ' distributed denial-of-service ' attacks, potentially triggered on-demand through platforms offering DDoS-for-hire services. The botnet, named "dark_nexus" by Bitdefender researchers, works by employing credential stuffing attacks against a variety of devices, such as routers (from Dasan Zhone, Dlink, and ASUS), video recorders, and thermal cameras, to co-opt them into the botnet. So far, dark_nexus comprises at least 1,372 bots, acting as a reverse proxy, spanning across various locations in China, South Korea, Thailand, Brazil, and Russia. "While it might share some features with previously known IoT botnets, the way some of its modules have been developed makes it significantly more potent and robust," the researchers said . "For example, payloads are compiled for 12 different CPU architectures and dynamically deliver

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

International hotel chain Marriott today disclosed a data breach impacting nearly 5.2 million hotel guests, making it the second security incident to hit the company in recent years. "At the end of February 2020, we identified that an unexpected amount of guest information may have been accessed using the login credentials of two employees at a franchise property," Marriott said in a statement . "We believe this activity started in mid-January 2020. Upon discovery, we confirmed that the login credentials were disabled, immediately began an investigation, implemented heightened monitoring, and arranged resources to inform and assist guests." The incident exposed guests' personal information such as contact details (name, mailing address, email address, and phone number), loyalty account information (account number and points balance), and additional information such as company, gender, dates of births, room preferences, and language preferences. The ho

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-

As the world comes to grips with the coronavirus pandemic , the situation has proven to be a blessing in disguise for threat actors, who've taken advantage of the opportunity to target victims with scams or malware campaigns. Now, according to a new report published by Check Point Research today and shared with The Hacker News, hackers are exploiting the COVID-19 outbreak to spread their own infections, including registering malicious Coronavirus-related domains and selling discounted off-the-shelf malware in the dark web. "Special offers by different hackers promoting their 'goods' — usually malicious malware or exploit tools — are being sold over the darknet under special offers with 'COVID19' or 'coronavirus' as discount codes, targeting wannabe cyber-attackers," the cybersecurity firm said. COVID-19 Discounts: Exploit Tools for Sale The report comes following an uptick in the number of malicious coronavirus-related domains that hav

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

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

Image credit: Times of Israel. Aleksei Burkov, a 29-year-old Russian hacker, on Thursday pleaded guilty to multiple criminal charges for running two illegal websites that helped cyber criminals commit more than $20 million in credit card fraud. The first website Burkov operated was an online marketplace for buying and selling stolen credit card and debit card numbers—called Cardplanet —which roughly hosted 150,000 payment card details between the years 2009 and 2013. Cardplanet marketplace offered stolen payment card details for anywhere between $2.50 and $10 a card, depending on the card type, country of origin, and the availability of card owner information. The carding website even offered a paid service that allowed buyers to instantly verify if a stolen payment card were still valid. "Many of the cards offered for sale belonged to U.S. citizens. The stolen credit card data from more than 150,000 compromised payment cards was allegedly sold on Burkov's site and

It's now or never to prevent your enterprise servers running vulnerable versions of Citrix application delivery, load balancing, and Gateway solutions from getting hacked by remote attackers. Why the urgency? Earlier today, multiple groups publicly released weaponized proof-of-concept exploit code [ 1 , 2 ] for a recently disclosed remote code execution vulnerability in Citrix's NetScaler ADC and Gateway products that could allow anyone to leverage them to take full control over potential enterprise targets. Just before the last Christmas and year-end holidays, Citrix announced that its Citrix Application Delivery Controller (ADC) and Citrix Gateway are vulnerable to a critical path traversal flaw (CVE-2019-19781) that could allow an unauthenticated attacker to perform arbitrary code execution on vulnerable servers. Citrix confirmed that the flaw affects all supported version of the software, including: Citrix ADC and Citrix Gateway version 13.0 all supported build

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

A British man suspected to be a member of ' The Dark Overlord ,' an infamous international hacking group, has finally been extradited to the United States after being held for over two years in the United Kingdom. Nathan Francis Wyatt , 39, appeared in federal court in St. Louis, Missouri, on Wednesday to face charges related to his role in hacking healthcare and accounting companies in the U.S. and then threatening to publish stolen information unless victims paid a ransom in Bitcoin. According to a court indictment unsealed yesterday, Wyatt faces one count of conspiracy, two counts of aggravated identity theft and three counts of threatening to damage a protected computer. However, the suspect has not yet pledged guilty to any of the charges in the U.S. federal court, where he appeared after fighting for 11 months to avoid being extradited from Britain. Cyber Attacks by The Dark Overlord Group British police first arrested Wyatt in September 2016 during an inves

Cybercriminals are busy innovators, adapting their weapons and attack strategies, and ruthlessly roaming the web in search of their next big score. Every manner of sensitive information, such as confidential employee records, customers' financial data, protected medical documents, and government files, are all subject to their relentless threats to cybersecurity . Solutions span a broad spectrum, from training email users to ensuring a VPN kill switch is in place, to adding extensive advanced layers of network protection. To successfully guard against severe threats from hackers, worm viruses to malware, such as botnet attacks, network managers need to use all tools and methods that fit well into a comprehensive cyber defense strategy. Of all the menaces mentioned above to a website owner's peace of mind, botnets arguably present the most unsettling form of security risk. They're not the mere achievements of malicious amateur cybercriminals. They're state
