A new variant of the notorious Mirai botnet has been found leveraging several security vulnerabilities to propagate itself to Linux and IoT devices. Observed during the second half of 2022, the new version has been dubbed  V3G4  by Palo Alto Networks Unit 42, which identified three different campaigns likely conducted by the same threat actor. "Once the vulnerable devices are compromised, they will be fully controlled by attackers and become a part of the botnet," Unit 42 researchers  said . "The threat actor has the capability to utilize those devices to conduct further attacks, such as distributed denial-of-service (DDoS) attacks." The attacks primarily single out exposed servers and networking devices running Linux, with the adversary weaponizing as many as 13 flaws that could lead to remote code execution (RCE). Some of the notable flaws relate to critical flaws in Atlassian Confluence Server and Data Center, DrayTek Vigor routers, Airspan AirSpot, and Geu...

Cisco has rolled out security updates to address a critical flaw reported in the ClamAV open source antivirus engine that could lead to remote code execution on susceptible devices. Tracked as  CVE-2023-20032  (CVSS score: 9.8), the issue relates to a case of remote code execution residing in the HFS+ file parser component. The flaw affects versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier. Google security engineer Simon Scannell has been credited with discovering and reporting the bug. "This vulnerability is due to a missing buffer size check that may result in a heap buffer overflow write," Cisco Talos  said  in an advisory. "An attacker could exploit this vulnerability by submitting a crafted HFS+ partition file to be scanned by ClamAV on an affected device." Successful exploitation of the weakness could enable an adversary to run arbitrary code with the same privileges as that of the ClamAV scanning process, or crash the process, resu...

A popular npm package with more than 3.5 million weekly downloads has been found vulnerable to an account takeover attack. "The package can be taken over by recovering an expired domain name for one of its maintainers and resetting the password," software supply chain security company Illustria  said  in a report. While npm's security protections limit users to have only one active email address per account, the Israeli firm said it was able to reset the GitHub password using the recovered domain. The attack, in a nutshell, grants a threat actor access to the package's associated GitHub account, effectively making it possible to publish trojanized versions to the npm registry that can be weaponized to conduct supply chain attacks at scale. This is achieved by taking advantage of a GitHub Action that's configured in the repository to automatically publish the packages when new code changes are pushed. "Even though the maintainer's npm user account i...

The prolific  SideWinder  group has been attributed as the nation-state actor behind attempted attacks against 61 entities in Afghanistan, Bhutan, Myanmar, Nepal, and Sri Lanka between June and November 2021. Targets included government, military, law enforcement, banks, and other organizations, according to an  exhaustive report  published by Group-IB, which also found links between the adversary and two other intrusion sets tracked as Baby Elephant and  DoNot Team . SideWinder  is also referred to as APT-C-17, Hardcore Nationalist (HN2), Rattlesnake, Razor Tiger, and T-APT4. It's suspected to be of Indian origin, although Kaspersky in 2022 noted that the attribution is no longer deterministic. The  group  has been linked to  no less than 1,000 attacks  against government organizations in the Asia-Pacific region since April 2020, according to a report from the Russian cybersecurity firm early last year. Of the 61 potential targets...

Chinese-speaking individuals in Southeast and East Asia are the targets of a new rogue Google Ads campaign that delivers remote access trojans such as FatalRAT to compromised machines. The attacks involve purchasing ad slots to appear in Google search results and direct users looking for popular applications to rogue websites hosting trojanized installers, ESET said in a report published today. The ads have since been taken down. Some of the spoofed applications include Google Chrome, Mozilla Firefox, Telegram, WhatsApp, LINE, Signal, Skype, Electrum, Sogou Pinyin Method, Youdao, and WPS Office. "The websites and installers downloaded from them are mostly in Chinese and in some cases falsely offer Chinese language versions of software that is not available in China," the Slovak cybersecurity firm  said , adding it observed the attacks between August 2022 and January 2023. A majority of the victims are located in Taiwan, China, and Hong Kong, followed by Malaysia, Japan, ...

Security researchers have disclosed two new vulnerabilities affecting Schneider Electric Modicon programmable logic controllers (PLCs) that could allow for authentication bypass and remote code execution. The flaws, tracked as  CVE-2022-45788  (CVSS score: 7.5) and  CVE-2022-45789  (CVSS score: 8.1), are part of a  broader collection  of  security defects  tracked by Forescout as OT:ICEFALL. Successful exploitation of the bugs could enable an adversary to execute unauthorized code, denial-of-service, or disclosure of sensitive information. The cybersecurity company said the shortcomings can be chained by a threat actor with known flaws from other vendors (e.g.,  CVE-2021-31886 ) to achieve deep lateral movement in operational technology (OT) networks. "Deep lateral movement lets attackers gain deep access to industrial control systems and cross often overlooked security perimeters, allowing them to perform highly granular and stealthy ...

Security teams typically have great visibility over most areas, for example, the corporate network, endpoints, servers, and cloud infrastructure. They use this visibility to enforce the necessary security and compliance requirements. However, this is not the case when it comes to sensitive data sitting in production or analytic databases, data warehouses or data lakes. Security teams have to rely on data teams to locate sensitive data and enforce access controls and security policies. This is a huge headache for both the security and data teams. It weakens the business's security and compliance putting it at risk of exposing sensitive data, large fines, reputational damages, and more. Also, in many cases, it slows down the business's ability to scale up data operations.  This article examines how Satori, a data security platform, gives control of the sensitive data in databases, data warehouses and data lakes to the security teams. Satori's  automated data security plat...

Telecommunication service providers in the Middle East are being targeted by a previously undocumented threat actor as part of a suspected intelligence gathering mission. Cybersecurity firms SentinelOne and QGroup are tracking the activity cluster under the former's work-in-progress moniker  WIP26 . "WIP26 relies heavily on public cloud infrastructure in an attempt to evade detection by making malicious traffic look legitimate," researchers Aleksandar Milenkoski, Collin Farr, and Joey Chen  said  in a report shared with The Hacker News. This includes the misuse of Microsoft 365 Mail, Azure, Google Firebase, and Dropbox for malware delivery, data exfiltration, and command-and-control (C2) purposes. The initial intrusion vector used in the attacks entails "precision targeting" of employees via WhatsApp messages that contain links to Dropbox links to supposedly benign archive files. The files, in reality, harbor a malware loader whose core feature is to depl...

More than 500 hosts have been newly compromised en masse by the ESXiArgs ransomware strain, most of which are located in France, Germany, the Netherlands, the U.K., and Ukraine. The  findings  come from attack surface management firm Censys, which  discovered  "two hosts with strikingly similar ransom notes dating back to mid-October 2022, just after ESXi versions 6.5 and 6.7 reached end of life." The first set of infections dates back to October 12, 2022, much earlier than when the campaign  began to gain traction  at the start of February 2023. Then on January 31, 2023, the ransom notes on the two hosts are said to have been updated with a revised version that matches the ones used in the current wave. Some of the crucial differences between the two ransom notes include the use of an onion URL instead of a Tox chat ID, a Proton Mail address at the bottom of the note, and a lower ransom demand (1.05 Bitcoin vs. 2.09 Bitcoin). "Each variant of the ran...
