Ivanti has rolled out security updates for a critical flaw in Virtual Traffic Manager (vTM) that could be exploited to achieve an authentication bypass and create rogue administrative users. The vulnerability, tracked as CVE-2024-7593, has a CVSS score of 9.8 out of a maximum of 10.0. "Incorrect implementation of an authentication algorithm in Ivanti vTM other than versions 22.2R1 or 22.7R2 allows a remote unauthenticated attacker to bypass authentication of the admin panel," the company said in an advisory. It impacts the following versions of vTM - 22.2 (fixed in version 22.2R1) 22.3 (fixed in version 22.3R3, available week of August 19, 2024) 22.3R2 (fixed in version 22.3R3, available week of August 19, 2024) 22.5R1 (fixed in version 22.5R2, available week of August 19, 2024) 22.6R1 (fixed in version 22.6R2, available week of August 19, 2024) 22.7R1 (fixed in version 22.7R2) As temporary mitigation, Ivanti is recommending customers to limit admin access to th...

The China-backed threat actor known as Earth Baku has diversified its targeting footprint beyond the Indo-Pacific region to include Europe, the Middle East, and Africa starting in late 2022. Newly targeted countries as part of the activity include Italy, Germany, the U.A.E., and Qatar, with suspected attacks also detected in Georgia and Romania. Governments, media and communications, telecoms, technology, healthcare, and education are some of the sectors singled out as part of the intrusion set. "The group has updated its tools, tactics, and procedures (TTPs) in more recent campaigns, making use of public-facing applications such as IIS servers as entry points for attacks, after which they deploy sophisticated malware toolsets on the victim's environment," Trend Micro researchers Ted Lee and Theo Chen said in an analysis published last week. The findings build upon recent reports from Zscaler and Google-owned Mandiant , which also detailed the threat actor's u...

A team of researchers from the CISPA Helmholtz Center for Information Security in Germany has disclosed an architectural bug impacting Chinese chip company T-Head's XuanTie C910 and C920 RISC-V CPUs that could allow attackers to gain unrestricted access to susceptible devices. The vulnerability has been codenamed GhostWrite. It has been described as a direct CPU bug embedded in the hardware, as opposed to a side-channel or transient execution attack. "This vulnerability allows unprivileged attackers, even those with limited access, to read and write any part of the computer's memory and to control peripheral devices like network cards," the researchers said . "GhostWrite renders the CPU's security features ineffective and cannot be fixed without disabling around half of the CPU's functionality." CISPA found that the CPU has faulty instructions in its vector extension, an add-on to the RISC-V ISA designed to handle larger data values than the base Instru...

Cybersecurity researchers have discovered two security flaws in Microsoft's Azure Health Bot Service that, if exploited, could permit a malicious actor to achieve lateral movement within customer environments and access sensitive patient data. The critical issues, now patched by Microsoft, could have allowed access to cross-tenant resources within the service, Tenable said in a new report shared with The Hacker News. The Azure AI Health Bot Service is a cloud platform that enables developers in healthcare organizations to build and deploy AI-powered virtual health assistants and create copilots to manage administrative workloads and engage with their patients. This includes bots created by insurance service providers to allow customers to look up the status of a claim and ask questions about benefits and services, as well as bots managed by healthcare entities to help patients find appropriate care or look up nearby doctors. Tenable's research specifically focuses on on...

Traditionally, the focus has been on defending against digital threats such as malware, ransomware, and phishing attacks by detecting them and responding. However, as cyber threats become more sophisticated. There is a growing recognition of the importance of measures that stop new attacks before they are recognized. With high-value assets, it's not good enough to have the protection, it's essential to have some assurance that the protection is effective. With software, that assurance is hard work, and this has led to a complimentary approach, called hardsec. What is Hardsec? Short for " Hardware Security ." Hardsec is about using hardware logic and electronics to implement a security defence, rather than through software alone - thereby providing a higher level of security assurance and resilience against both external and insider threats . Making it an essential component of comprehensive cybersecurity strategies. The Rise of Sophisticated Attacks When the impact of an attack ag...

The U.S. Federal Bureau of Investigation (FBI) on Monday announced the disruption of online infrastructure associated with a nascent ransomware group called Radar/Dispossessor. The effort saw the dismantling of three U.S. servers, three United Kingdom servers, 18 German servers, eight U.S.-based criminal domains, and one German-based criminal domain. Dispossessor is said to be led by individual(s) who go by the online moniker "Brain." "Since its inception in August 2023, Radar/Dispossessor has quickly developed into an internationally impactful ransomware group, targeting and attacking small-to-mid-sized businesses and organizations from the production, development, education, healthcare, financial services, and transportation sectors," the FBI said in a statement. As many as 43 companies have been identified as victims of Dispossessor attacks, including those located in Argentina, Australia, Belgium, Brazil, Canada, Croatia, Germany, Honduras, India, Peru, Pol...

The Computer Emergency Response Team of Ukraine (CERT-UA) has warned of a new phishing campaign that masquerades as the Security Service of Ukraine to distribute malware capable of remote desktop access. The agency is tracking the activity under the name UAC-0198. More than 100 computers are estimated to have been infected since July 2024, including those related to government bodies in the country. The attack chains involve the mass distribution of emails to deliver a ZIP archive file containing an MSI installer file, the opening of which leads to the deployment of malware called ANONVNC. ANONVNC, which is based on an open-source remote management tool called MeshAgent , allows for stealthy unauthorized access to the infected hosts. The development comes as CERT-UA attributed the hacking group UAC-0102 to phishing attacks propagating HTML attachments that mimic the login page of UKR.NET to steal users' credentials. Over the past few weeks, the agency has also warned of a ...

In 2023, no fewer than 94 percent of businesses were impacted by phishing attacks, a 40 percent increase compared to the previous year, according to research from Egress . What's behind the surge in phishing? One popular answer is AI – particularly generative AI, which has made it trivially easier for threat actors to craft content that they can use in phishing campaigns, like malicious emails and, in more sophisticated cases, deepfake videos . In addition, AI can help write the malware that threat actors often plant on their victims' computers and servers as part of phishing campaigns. Phishing as a Service , or PhaaS, is another development sometimes cited to explain why phishing threats are at an all-time high. By allowing malicious parties to hire skilled attackers to carry out phishing campaigns for them, PhaaS makes it easy for anyone with a grudge – or a desire to exfiltrate some money from unsuspecting victims – to launch phishing attacks. Phishing has become agil...

Cybersecurity researchers have identified a number of security shortcomings in photovoltaic system management platforms operated by Chinese companies Solarman and Deye that could enable malicious actors to cause disruption and power blackouts. "If exploited, these vulnerabilities could allow an attacker to control inverter settings that could take parts of the grid down, potentially causing blackouts," Bitdefender researchers said in an analysis published last week. The vulnerabilities have been addressed by Solarman and Deye as of July 2024, following responsible disclosure on May 22, 2024. The Romanian cybersecurity vendor, which analyzed the two PV monitoring and management platforms, said they suffer from a number of issues that, among others, could result in account takeover and information disclosure. A brief description of the issues is listed below - Full Account Takeover via Authorization Token Manipulation Using the /oauth2-s/oauth/token API endpoint  Deye...

After a good year of sustained exuberance, the hangover is finally here. It's a gentle one (for now), as the market corrects the share price of the major players (like Nvidia, Microsoft, and Google), while other players reassess the market and adjust priorities. Gartner calls it the trough of disillusionment , when interest wanes and implementations fail to deliver the promised breakthroughs. Producers of the technology shake out or fail. Investment continues only if the surviving providers improve their products to the satisfaction of early adopters.  Let's be clear, this was always going to be the case: the post-human revolution promised by the AI cheerleaders was never a realistic goal, and the incredible excitement triggered by the early LLMs was not based on market success.  AI is here to stay  What's next for AI then? Well, if it follows the Gartner hype cycle, the deep crash is followed by the slope of enlightenment where the maturing technology regains its foo...

The maintainers of the FreeBSD Project have released security updates to address a high-severity flaw in OpenSSH that attackers could potentially exploit to execute arbitrary code remotely with elevated privileges. The vulnerability, tracked as CVE-2024-7589 , carries a CVSS score of 7.4 out of a maximum of 10.0, indicating high severity. "A signal handler in sshd(8) may call a logging function that is not async-signal-safe," according to an advisory released last week. "The signal handler is invoked when a client does not authenticate within the LoginGraceTime seconds (120 by default). This signal handler executes in the context of the sshd(8)'s privileged code, which is not sandboxed and runs with full root privileges." OpenSSH is an implementation of the secure shell (SSH) protocol suite, providing encrypted and authenticated transport for a variety of services, including remote shell access. CVE-2024-7589 has been described as "another instance...

Security vulnerabilities have been disclosed in the industrial remote access solution Ewon Cosy+ that could be abused to gain root privileges to the devices and stage follow-on attacks. The elevated access could then be weaponized to decrypt encrypted firmware files and encrypted data such as passwords in configuration files, and even get correctly signed X.509 VPN certificates for foreign devices to take over their VPN sessions. "This allows attackers hijacking VPN sessions which results in significant security risks against users of the Cosy+ and the adjacent industrial infrastructure," SySS GmbH security researcher Moritz Abrell said in a new analysis. The findings were presented at the DEF CON 32 conference over the weekend. Following responsible disclosure, the issues have been addressed in firmware versions 21.2s10 and 22.1s3 as part of an advisory [PDF] issued by Ewon on July 29, 2024 - CVE-2024-33892 (CVSS score: 7.4) - Information leakage through cookies ...

The Russian government and IT organizations are the target of a new campaign that delivers a number of backdoors and trojans as part of a spear-phishing campaign codenamed EastWind . The attack chains are characterized by the use of RAR archive attachments containing a Windows shortcut (LNK) file that, upon opening, activates the infection sequence, culminating in the deployment of malware such as GrewApacha, an updated version of the CloudSorcerer backdoor, and a previously undocumented implant dubbed PlugY. PlugY is "downloaded through the CloudSorcerer backdoor, has an extensive set of commands and supports three different protocols for communicating with the command-and-control server," Russian cybersecurity company Kaspersky said . The initial infection vector relies on a booby-trapped LNK file, which employs DLL side-loading techniques to launch a malicious DLL file that uses Dropbox as a communications mechanism to execute reconnaissance commands and download add...

Cybersecurity researchers have discovered a new malicious package on the Python Package Index (PyPI) repository that masquerades as a library from the Solana blockchain platform but is actually designed to steal victims' secrets. "The legitimate Solana Python API project is known as 'solana-py' on GitHub, but simply ' solana ' on the Python software registry, PyPI," Sonatype researcher Ax Sharma said in a report published last week. "This slight naming discrepancy has been leveraged by a threat actor who published a 'solana-py' project on PyPI." The malicious "solana-py" package attracted a total of 1,122 downloads since it was published on August 4, 2024. It's no longer available for download from PyPI. The most striking aspect of the library is that it carried the version numbers 0.34.3, 0.34.4, and 0.34.5. The latest version of the legitimate "solana" package is 0.34.3. This clearly indicates an attempt o...

As many as 10 security flaws have been uncovered in Google's Quick Share data transfer utility for Android and Windows that could be assembled to trigger remote code execution (RCE) chain on systems that have the software installed. "The Quick Share application implements its own specific application-layer communication protocol to support file transfers between nearby, compatible devices," SafeBreach Labs researchers Or Yair and Shmuel Cohen said in a technical report shared with The Hacker News. "By investigating how the protocol works, we were able to fuzz and identify logic within the Quick Share application for Windows that we could manipulate or bypass." The result is the discovery of 10 vulnerabilities – nine affecting Quick Share for Windows and one impacting Android – that could be fashioned into an "innovative and unconventional" RCE attack chain to run arbitrary code on Windows hosts. The RCE attack chain has been codenamed QuickShell ...

An ongoing, widespread malware campaign has been observed installing rogue Google Chrome and Microsoft Edge extensions via a trojan distributed via fake websites masquerading as popular software. "The trojan malware contains different deliverables ranging from simple adware extensions that hijack searches to more sophisticated malicious scripts that deliver local extensions to steal private data and execute various commands," the ReasonLabs research team said in an analysis. "This trojan malware, existing since 2021, originates from imitations of download websites with add-ons to online games and videos." The malware and the extensions have a combined reach of at least 300,000 users of Google Chrome and Microsoft Edge, indicating that the activity has a broad impact. At the heart of the campaign is the use of malvertising to push lookalike websites promoting known software like Roblox FPS Unlocker, YouTube, VLC media player, Steam, or KeePass to trick users s...
