Cybersecurity researchers on Thursday revealed details about a new Mirai-inspired botnet called "mirai_ptea" that leverages an undisclosed vulnerability in digital video recorders (DVR) provided by KGUARD to propagate and carry out distributed denial-of-service (DDoS) attacks. Chinese security firm Netlab 360  pinned  the first probe against the flaw on March 23, 2021, before it detected active exploitation attempts by the botnet on June 22, 2021. The Mirai botnet, since  emerging on the scene  in 2016, has been linked to a string of large-scale DDoS attacks, including one against  DNS service provider Dyn  in October 2016, causing major internet platforms and services to remain inaccessible to users in Europe and North America. Since then,  numerous   variants  of  Mirai  have  sprung up  on the threat landscape, in part due to the availability of its source code on the Internet. Mirai_ptea is no exception. Not much has been disclosed about the security flaw in an att

Cybersecurity researchers are warning of ongoing attacks coordinated by a suspected Chinese-speaking threat actor targeting the Afghanistan government as part of an espionage campaign that may have had its provenance as far back as 2014. Israeli cybersecurity firm Check Point Research attributed the intrusions to a hacking group tracked under the moniker "IndigoZebra," with past activity aimed at other central-Asian countries, including Kyrgyzstan and Uzbekistan. "The threat actors behind the espionage leveraged Dropbox, the popular cloud-storage service, to infiltrate the Afghan National Security Council (NSC)," the researchers said in a technical write-up shared with The Hacker News, adding they "orchestrated a ministry-to-ministry style deception, where an email is sent to a high-profile target from the mailboxes of another high-profile victim." IndigoZebra first came to light in August 2017 when Kaspersky  detailed  a covert operation that single

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

The recent tsunami of ransomware has brought to life the fears of downtime and data loss cybersecurity pros have warned about, as attacks on the energy sector, food supply chain, healthcare industry, and other critical infrastructure have grabbed headlines. For the industry experts who track the evolution of this threat, the increased frequency, sophistication, and destructiveness of ransomware suggests that businesses still have some major gaps in their defense strategies. It's no surprise that a new, multi-layered approach to protection is needed to stem the damage caused by ransomware. But what changes should an IT team implement to close those gaps? During a recent panel, a team of cybersecurity experts outlined a three-step plan to do just that -- centered around embracing new technologies, improving security processes, and ensuring their people know how to help curb the threat. 1  —  New Strains Overwhelm Old Defenses Many new ransomware strains now act like advanced pe

Colombian authorities on Wednesday said they have arrested a Romanian hacker who is wanted in the U.S. for distributing a virus that infected more than a million computers from 2007 to 2012. Mihai Ionut Paunescu (aka "Virus"), the individual in question, was detained at the El Dorado airport in Bogotá, the Office of the Attorney General of Colombia  said . Paunescu was  previously charged  by the U.S. Department of Justice (DoJ) in January 2013 for operating a bulletproof hosting service that "enabled cyber criminals to distribute the Gozi Virus, the Zeus Trojan and other notorious malware, and conduct other sophisticated cyber crimes." He was arrested in Romania in December 2012 but managed to avoid extradition to the U.S. "Through this service, Paunescu, like other bulletproof hosts, knowingly provided critical online infrastructure to cyber criminals that allowed them to commit online criminal activity with little fear of detection by law enforcement,&

Organizations today already have an overwhelming number of dangers and threats to look out for, from spam to phishing attempts to new infiltration and ransomware tactics. There is no chance to rest, since attack groups are constantly looking for more effective means of infiltrating and infecting systems. Today, there are hundreds of groups devoted to infiltrating almost every industry, constantly devising more sophisticated methods to attack organizations. It's even more troubling to note that some groups have started to collaborate, creating complex and stealthy tactics that leave even the best security teams scrambling to respond. Such is the case noted by XDR Provider Cynet, as the company observes in its newest Research Webinar ( register here ). Cynet's research team noted that two of the most infamous attack groups – Lunar Spider and Wizard Spider – have started working together to infect organizations with ransomware. The development is certainly troubling, and the

Microsoft on Friday said it's investigating an incident wherein a driver signed by the company turned out to be a malicious Windows rootkit that was observed communicating with command-and-control (C2) servers located in China. The driver, called " Netfilter ," is said to target gaming environments, specifically in the East Asian country, with the Redmond-based firm noting that "the actor's goal is to use the driver to spoof their geo-location to cheat the system and play from anywhere." "The malware enables them to gain an advantage in games and possibly exploit other players by compromising their accounts through common tools like keyloggers," Microsoft Security Response Center (MSRC)  said . It's worth pointing out that Netfilter also refers to a legitimate software package , which enables packet filtering and network address translation for Linux based systems. Microsoft dubbed the malware " Retliften ," alluding to "ne

There has been a lot of buzz in the industry about ransomware lately. Almost every other day, it's making headlines. With businesses across the globe holding their breath, scared they might fall victim to the next major ransomware attack, it is now time to take action. The FBI IC3 report of 2020 classified Ransomware as the most financially damaging cybercrime of the year, with no major improvement in 2021. Wouldn't it be nice if you could prevent a ransomware attack from occurring in the first place?  DMARC  can make this seemingly impossible claim a possibility for domain owners!  Multiple benefits arise from your DMARC implementation over time, including an increase in the deliverability of your email as well as a higher domain reputation. DMARC is also known as the first line of defense against Ransomware. Let's take a closer look. What are the Risks Associated with Ransomware?  Ransomware is malicious software that installs itself on your computer without your p

A previously undocumented Windows malware has infected over 222,000 systems worldwide since at least June 2018, yielding its developer no less than 9,000 Moneros ($2 million) in illegal profits. Dubbed " Crackonosh ," the malware is distributed via illegal, cracked copies of popular software, only to disable antivirus programs installed in the machine and install a coin miner package called XMRig for stealthily exploiting the infected host's resources to mine Monero. At least 30 different versions of the malware executable have been discovered between Jan. 1, 2018, and Nov. 23, 2020, Czech cybersecurity software company Avast  said  on Thursday, with a majority of the victims located in the U.S., Brazil, India, Poland, and the Philippines. Crackonosh works by replacing critical Windows system files such as "serviceinstaller.msi" and "maintenance.vbs" to cover its tracks and abuses the  safe mode , which prevents antivirus software from working, to

A Ukrainian national and a mid-​level supervisor of the hacking group known as FIN7 has been sentenced to seven years in prison for his role as a "pen tester" and perpetuating a criminal scheme that enabled the gang to compromise millions of customers debit and credit cards. Andrii Kolpakov , 33, was arrested in Spain on June 28, 2018, and subsequently extradited to the U.S. the following year on June 1, 2019. In June 2020, Kolpakov pleaded guilty to one count of conspiracy to commit wire fraud and one count of conspiracy to commit computer hacking. The Western District of Washington also ordered Kolpakov to pay $2.5 million in restitution. The defendant, who was involved with the group from April 2016 until his arrest, managed other hackers who were tasked with breaching the point-of-sale systems of companies, both in the U.S. and elsewhere, to deploy malware capable of stealing financial information. FIN7 , also called Anunak, Carbanak Group , and the Navigator Group,

The cybercrime ring that was apprehended last week in connection with Clop (aka Cl0p) ransomware attacks against dozens of companies in the last few months helped launder money totaling $500 million for several malicious actors through a plethora of illegal activities. "The group — also known as FANCYCAT — has been running multiple criminal activities: distributing cyber attacks; operating a high-risk exchanger; and laundering money from dark web operations and high-profile cyber attacks such as Cl0p and Petya ransomware," popular cryptocurrency exchange Binance  said  Thursday. On June 16, the Ukraine Cyber Police  nabbed six individuals  in the city of Kyiv, describing the arrests as resulting from an international operation involving law enforcement authorities from Korea, the U.S., and Interpol. While the bust was seen as a major blow to the operations of the Clop gang, the hackers published earlier this week a fresh batch of confidential employee records stolen from

A threat actor with suspected ties to Pakistan has been striking government and energy organizations in the South and Central Asia regions to deploy a remote access trojan on compromised Windows systems, according to new research. "Most of the organizations that exhibited signs of compromise were in India, and a small number were in Afghanistan," Lumen's Black Lotus Labs  said  in a Tuesday analysis. "The potentially compromised victims aligned with the government and power utility verticals." Some of the victims include a foreign government organization, a power transmission organization, and a power generation and transmission organization. The covert operation is said to have begun at least in January 2021. The intrusions are notable for a number of reasons, not least because in addition to its highly-targeted nature, the tactics, techniques, and procedures (TTPs) adopted by the adversary rely on repurposed open-source code and the use of compromised dom

Cybersecurity researchers are sounding the alarm bell over a new ransomware strain called " DarkRadiation " that's implemented entirely in Bash and targets Linux and Docker cloud containers, while banking on messaging service Telegram for command-and-control (C2) communications. "The ransomware is written in  Bash  script and targets Red Hat/CentOS and Debian Linux distributions," researchers from Trend Micro  said  in a report published last week. "The malware uses OpenSSL's AES algorithm with CBC mode to encrypt files in various directories. It also uses Telegram's API to send an infection status to the threat actor(s)." As of writing, there's no information available on the delivery methods or evidence that the ransomware has been deployed in real-world attacks. The findings come from an analysis of a collection of hacking tools hosted on the unidentified threat actor's infrastructure (IP address "185.141.25.168") in a

Hackers are increasingly using ransomware as an effective tool to disrupt businesses and fund malicious activities. A recent analysis by cybersecurity company Group-IB revealed  ransomware attacks doubled in 2020 , while Cybersecurity Ventures predicts that a ransomware attack will occur every 11 seconds  in 2021. Businesses must prepare for the possibility of a ransomware attack affecting their data, services, and business continuity. What steps are involved in recovering from a ransomware attack? Isolate and shutdown critical systems Enact your business continuity plan Report the cyberattack Restore from backup Remediate, patch, and monitor Isolate and shutdown critical systems The first important step is to isolate and shut down business-critical systems. There is a chance the ransomware has not affected all accessible data and systems. Shutting down and isolating both infected systems and healthy systems helps contain malicious code. From the first evidence of ransomwa

A new research published by a group of academics has found that anti-virus programs for Android continue to remain vulnerable against different permutations of malware, in what could pose a serious risk as malicious actors evolve their toolsets to better evade analysis. "Malware writers use stealthy mutations (morphing/obfuscations) to continuously develop malware clones, thwarting detection by signature based detectors," the researchers  said . "This attack of clones seriously threatens all the mobile platforms, especially Android." The findings were published in a study last week by researchers from Adana Science and Technology University, Turkey, and the National University of Science and Technology, Islamabad, Pakistan. Unlike iOS, apps can be downloaded from third-party sources on Android devices, raising the possibility that unwitting users can install unverified and lookalike apps that clone a legitimate app's functionality but are built to trick tar

South Korea's state-run Korea Atomic Energy Research Institute (KAERI) on Friday disclosed that its internal network was infiltrated by suspected attackers operating out of its northern counterpart. The intrusion is said to have taken place on May 14 through a vulnerability in an unnamed virtual private network (VPN) vendor and involved a  total of 13 IP addresses , one of which — "27.102.114[.]89" — has been previously linked to a state-sponsored threat actor dubbed  Kimsuky . KAERI, established in 1959 and situated in the city of Daejeon, is a government-funded research institute that designs and develops nuclear technologies related to reactors, fuel rods, radiation fusion, and nuclear safety. Following the intrusion, the think tank said it took steps to block the attacker's IP addresses in question and applied necessary security patches to the vulnerable VPN solution. "Currently, the Atomic Energy Research Institute is investigating the subject of the ha

A string of cyber espionage campaigns dating all the way back to 2014 and likely focused on gathering defense information from neighbouring countries have been linked to a Chinese military-intelligence apparatus. In a wide-ranging report published by Massachusetts-headquartered Recorded Future this week, the cybersecurity firm's Insikt Group said it identified ties between a group it tracks as " RedFoxtrot " to the People's Liberation Army (PLA) Unit 69010 operating out of Ürümqi, the capital of the Xinjiang Uyghur Autonomous Region in the country. Previously called the Lanzhou Military Region's Second Technical Reconnaissance Bureau, Unit 69010 is a military cover for a Technical Reconnaissance Bureau (TRB) within China's Strategic Support Force (SSF) Network Systems Department ( NSD ). The connection to PLA Unit 69010 stems from what the researchers said were "lax operational security measures" adopted by an unnamed suspected RedFoxtrot threa

It's natural to get complacent with the status quo when things seem to be working. The familiar is comfortable, and even if something better comes along, it brings with it many unknowns. In cybersecurity, this tendency is countered by the fast pace of innovation and how quickly technology becomes obsolete, often overnight. This combination usually results in one of two things – organizations make less than ideal choices about the software and tools they're adding, or security leaders simply cannot stay abreast of new developments and opt to stay put with their existing stack. The problem is that once you let one update pass you by, you're suddenly miles behind. A new eBook from XDR provider Cynet ( download here ) offers insights into factors that are clear signs organizations need to upgrade their detection and response tools to stay with the times. The eBook highlights several factors and questions that companies can ask themselves to determine whether they are okay

Google has rolled out yet another update to Chrome browser for Windows, Mac, and Linux to fix four security vulnerabilities, including one zero-day flaw that's being exploited in the wild. Tracked as  CVE-2021-30554 , the high severity flaw concerns a  use after free vulnerability  in WebGL (aka Web Graphics Library), a JavaScript API for rendering interactive 2D and 3D graphics within the browser. Successful exploitation of the flaw could mean corruption of valid data, leading to a crash, and even execution of unauthorized code or commands. The issue was reported to Google anonymously on June 15, Chrome technical program manager Srinivas Sista  noted , adding the company is "aware that an exploit for CVE-2021-30554 exists in the wild." While it's usually the norm to limit details of the vulnerability until a majority of users are updated with the fix, the development comes less than 10 days after Google addressed another zero-day vulnerability exploited in act
