The P2PInfect peer-to-peer (P2) worm has been observed employing previously undocumented initial access methods to breach susceptible Redis servers and rope them into a botnet. "The malware compromises exposed instances of the Redis data store by exploiting the replication feature," Cado Security researchers Nate Bill and Matt Muir  said  in a report shared with The Hacker News. "A common attack pattern against Redis in cloud environments is to exploit this feature using a malicious instance to enable replication. This is achieved via connecting to an exposed Redis instance and issuing the SLAVEOF command." The Rust-based malware was  first documented  by Palo Alto Networks Unit 42, calling out the malware's ability to exploit a critical Lua sandbox escape vulnerability ( CVE-2022-0543 , CVSS score: 10.0) to obtain a foothold into Redis instances. The campaign is believed to have commenced on or after June 29, 2023. However, the latest discovery suggests th...

Threat actors associated with the hacking crew known as Patchwork have been spotted targeting universities and research organizations in China as part of a recently observed campaign. The activity, according to  KnownSec 404 Team , entailed the use of a backdoor codenamed  EyeShell . Patchwork , also known by the names Operation Hangover and Zinc Emerson, is suspected to be a threat group that operates on behalf of India. Active since at least December 2015, attack chains mounted by the outfit have a narrow focus and tend to single out Pakistan and China with custom implants such as BADNEWS via spear-phishing and watering hole attacks. The adversarial collective has been found to share tactical overlaps with other cyber-espionage groups with an Indian connection, including  SideWinder  and the  DoNot Team . Earlier this May, Meta  disclosed  that it took down 50 accounts on Facebook and Instagram operated by Patchwork, which took advantage of rog...

Demand for Virtual CISO services is soaring. According to Gartner, the use of vCISO services among small and mid-size businesses and non-regulated enterprises was expected to grow by a whopping 1900% in just one year, from only 1% in 2021 to 20% in 2022! Offering vCISO services can be especially attractive for MSPs and MSSPs. By addressing their customers' needs for proactive cyber resilience, they can generate a growing amount of recurring revenue from existing and new customers. And all while differentiating themselves from the competition. vCISO services also enable upselling of additional products and services the MSP or MSSP specializes in. However, not all MSPs and MSSPs fully understand how to provide vCISO services . Some may be unsure about which services are expected from them. Others may not realize they are already providing vCISO services and have the potential to effortlessly broaden their offerings into a complete vCISO suite or package it differently to make it more ...

More details have emerged about a botnet called  AVRecon , which has been observed making use of compromised small office/home office (SOHO) routers as part of a multi-year campaign active since at least May 2021. AVRecon was  first disclosed  by Lumen Black Lotus Labs earlier this month as malware capable of executing additional commands and stealing victim's bandwidth for what appears to be an illegal proxy service made available for other actors. It has also surpassed QakBot in terms of scale, having infiltrated over 41,000 nodes located across 20 countries worldwide. "The malware has been used to create residential proxy services to shroud malicious activity such as password spraying, web-traffic proxying, and ad fraud," the researchers said in the report. This has been corroborated by new findings from KrebsOnSecurity and Spur.us, which last week  revealed  that "AVrecon is the malware engine behind a 12-year-old service called SocksEscort, which rents ...

Threat actors are creating fake websites hosting trojanized software installers to trick unsuspecting users into downloading a downloader malware called Fruity with the goal of installing remote trojans tools like Remcos RAT. "Among the software in question are various instruments for fine-tuning CPUs, graphic cards, and BIOS; PC hardware-monitoring tools; and some other apps," cybersecurity vendor Doctor Web  said  in an analysis.  "Such installers are used as a decoy and contain not only the software potential victims are interested in, but also the trojan itself with all its components." The exact initial access vector used in the campaign is unclear but it could potentially range from phishing to drive-by downloads to malicious ads. Users who land on the fake site are prompted to download a ZIP installer package. The installer, besides activating the standard installation process, stealthily drops the Fruity trojan, a Python-based malware that unpacks an MP...

Multiple security vulnerabilities have been disclosed in the Ninja Forms plugin for WordPress that could be exploited by threat actors to escalate privileges and steal sensitive data. The flaws, tracked as CVE-2023-37979, CVE-2023-38386, and CVE-2023-38393, impact versions 3.6.25 and below, Patchstack  said  in a report last week. Ninja Forms is installed on over 800,000 sites. A brief description of each of the vulnerabilities is below - CVE-2023-37979  (CVSS score: 7.1) - A POST-based reflected cross-site scripting (XSS) flaw that could allow any unauthenticated user to achieve privilege escalation on a target WordPress site by tricking privileged users to visit a specially crafted website. CVE-2023-38386  and  CVE-2023-38393  - Broken access control flaws in the form submissions export feature that could enable a bad actor with Subscriber and Contributor roles to export all Ninja Forms submissions on a WordPress site. Users of the plugin are reco...

A new Android malware strain called  CherryBlos  has been observed making use of optical character recognition (OCR) techniques to gather sensitive data stored in pictures. CherryBlos, per  Trend Micro , is distributed via bogus posts on social media platforms and comes with capabilities to steal cryptocurrency wallet-related credentials and act as a  clipper  to substitute wallet addresses when a victim copies a string matching a predefined format is copied to the clipboard. Once installed, the apps seek users' permissions to grant it accessibility permissions, which allows it to automatically grant itself additional permissions as required. As a defense evasion measure, users attempting to kill or uninstall the app by entering the Settings app are redirected back to the home screen. Besides displaying fake overlays on top of legitimate crypto wallet apps to steal credentials and make fraudulent fund transfers to an attacker-controlled address, CherryBlos u...

Apple has announced plans to require developers to submit reasons to use certain APIs in their apps starting later this year with the release of iOS 17, iPadOS 17, macOS Sonoma, tvOS 17, and watchOS 10 to prevent their abuse for data collection. "This will help ensure that apps only use these APIs for their intended purpose," the company  said  in a statement. "As part of this process, you'll need to select one or more approved reasons that accurately reflect how your app uses the API, and your app can only use the API for the reasons you've selected." The APIs that  require  reasons for use relate to the following - File timestamp APIs System boot time APIs Disk space APIs Active keyboard APIs, and User defaults APIs The iPhone maker said it's making the move to ensure that such APIs are not abused by app developers to collect device signals to carry out  fingerprinting , which could be employed to  uniquely identify users  across different...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday disclosed details of a "novel persistent backdoor" called  SUBMARINE  deployed by threat actors in connection with the hack on Barracuda Email Security Gateway (ESG) appliances. "SUBMARINE comprises multiple artifacts — including a SQL trigger, shell scripts, and a loaded library for a Linux daemon — that together enable execution with root privileges, persistence, command and control, and cleanup," the agency  said . The findings come from an analysis of malware samples obtained from an unnamed organization that had been compromised by threat actors exploiting a critical flaw in ESG devices,  CVE-2023-2868  (CVSS score: 9.8), which allows for remote command injection. Evidence gathered so far shows that the attackers behind the activity, a suspected China nexus-actor tracked by Mandiant as  UNC4841 , leveraged the flaw as a zero-day in October 2022 to gain initial access to vic...

Ivanti has disclosed yet another security flaw impacting Endpoint Manager Mobile (EPMM), formerly known as MobileIron Core, that it said has been weaponized as part of an exploit chain by malicious actors in the wild. The new vulnerability, tracked as  CVE-2023-35081  (CVSS score: 7.8), impacts supported versions 11.10, 11.9, and 11.8, as well as those that are currently end-of-life (EoL). "CVE-2023-35081 enables an authenticated administrator to perform arbitrary file writes to the EPMM server," the company  said  in an advisory. "This vulnerability can be used in conjunction with  CVE-2023-35078 , bypassing administrator authentication and ACLs restrictions (if applicable)." A successful exploit could allow a threat actor to write arbitrary files on the appliance, thereby enabling the malicious party to execute OS commands on the appliance as the tomcat user. "As of now we are only aware of the same limited number of customers impacted by CVE-2023-35078...

The threat actors linked to the malware loader known as IcedID have made updates to the BackConnect (BC) module that's used for post-compromise activity on hacked systems, new findings from Team Cymru reveal. IcedID, also called BokBot , is a strain of malware similar to  Emotet  and  QakBot  that started off as a banking trojan in 2017, before switching to the role of an initial access facilitator for other payloads. Recent versions of the malware have been  observed  removing functionality related to online banking fraud to prioritize ransomware delivery. The BackConnect (BC) module,  first documented  by Netresec in October 2022, relies on a proprietary command-and-control (C2) protocol to exchange commands between a server and the infected host. The protocol, which comes with a VNC component for remote access, has also been identified in other malware such as the now-discontinued  BazarLoader  and QakBot. In December 2022, Team ...

An ongoing cyber attack campaign has set its sights on Korean-speaking individuals by employing U.S. Military-themed document lures to trick them into running malware on compromised systems. Cybersecurity firm Securonix is tracking the activity under the name STARK#MULE . The scale of the attacks is currently not known, and it's not clear if any of these attack attempts turned out to be successful. "Based on the source and likely targets, these types of attacks are on par with past attacks stemming from typical North Korean groups such as APT37 as South Korea has historically been a primary target of the group, especially its government officials," security researchers Den Iuzvyk, Tim Peck, and Oleg Kolesnikov said in a report shared with The Hacker News. APT37, also known by the names Nickel Foxcroft, Reaper, Ricochet Chollima, and ScarCruft, is a  North Korean nation-state actor  that's known to exclusively focus on targets in its southern counterpart, specific...
