Cybersecurity researchers have disclosed five previously unreported security vulnerabilities affecting B. Braun's Infusomat Space Large Volume Pump and SpaceStation that could be abused by malicious parties to tamper with medication doses without any prior authentication. McAfee, which discovered and reported the flaws to the German medical and pharmaceutical device company on January 11, 2021,  said  the "modification could appear as a device malfunction and be noticed only after a substantial amount of drug has been dispensed to a patient, since the infusion pump displays exactly what was prescribed, all while dispensing potentially lethal doses of medication." The issues have been addressed by B. Braun in SpaceCom L82 or later, Battery Pack SP with WiFi:L82 or later, and DataModule compactplus version A12 or later. Infusion pumps are medical devices used to deliver intravenous fluids, such as nutrients and medications, into a patient's body in controlled amoun...

A computer retail company based in the U.S. was the target of a previously undiscovered implant called SideWalk as part of a recent campaign undertaken by a Chinese advanced persistent threat group primarily known for singling out entities in East and Southeast Asia. Slovak cybersecurity firm ESET attributed the malware to an advanced persistent threat it tracks under the moniker SparklingGoblin, an adversary believed to be connected to the Winnti umbrella group, noting its similarities to another backdoor dubbed  Crosswalk  that was put to use by the same threat actor in 2019. "SideWalk is a modular backdoor that can dynamically load additional modules sent from its C&C [command-and-control] server, makes use of Google Docs as a  dead drop resolver , and  Cloudflare workers  as a C&C server," ESET researchers Thibaut Passilly and Mathieu Tartare  said  in a report published Tuesday. "It can also properly handle communication behind a prox...

A modified version of the WhatsApp messaging app for Android has been trojanized to intercept text messages, serve malicious payloads, display full-screen ads, and sign up device owners for unwanted premium subscriptions without their knowledge. "The Trojan Triada snuck into one of these modified versions of the messenger called FMWhatsApp 16.80.0 together with the advertising software development kit (SDK)," researchers from Russian cybersecurity firm Kaspersky  said  in a technical write-up published Tuesday. "This is similar to  what happened with APKPure , where the only malicious code that was embedded in the app was a payload downloader." Modified versions of legitimate Android apps — a practice called Modding — are designed to perform functions not originally conceived or intended by the app developers. FMWhatsApp, billed as a custom build of WhatsApp, allows users to refashion the app with different themes, personalize icons, and hide features like last ...

A previously undisclosed "zero-click" exploit in Apple's iMessage was abused by Israeli surveillance vendor NSO Group to circumvent iOS security protections and target nine Bahraini activists. "The hacked activists included three members of Waad (a secular Bahraini political society), three members of the Bahrain Center for Human Rights, two exiled Bahraini dissidents, and one member of Al Wefaq (a Shiite Bahraini political society)," researchers from University of Toronto's Citizen Lab  said  in a report published today, with four of the targets hacked by an actor it tracks as LULU and believed to be the government of Bahrain. Citizen Lab called the new exploit chain "FORCEDENTRY." It's also a zero-click exploit, meaning that it can be used to trigger an infection simply by sending a malicious message to the target, even without having to click a link or view the message in question. "As always, if NSO receives reliable information r...

Cybersecurity researchers on Tuesday took the wraps off four up-and-coming ransomware groups that could pose a serious threat to enterprises and critical infrastructure, as the ripple effect of a recent spurt in ransomware incidents show that attackers are growing more sophisticated and more profitable in extracting payouts from victims. "While the ransomware crisis appears poised to get worse before it gets better, the cast of cybercrime groups that cause the most damage is constantly changing," Palo Alto Networks' Unit 42 threat intelligence team  said  in a report shared with The Hacker News. "Groups sometimes go quiet when they've achieved so much notoriety that they become a priority for law enforcement. Others reboot their operations to make them more lucrative by revising their tactics, techniques and procedures, updating their software and launching marketing campaigns to recruit new affiliates." The development comes as ransomware attacks are g...

More than 38 million records from 47 different entities that rely on Microsoft's Power Apps portals platform were inadvertently left exposed online, bringing into sharp focus a "new vector of data exposure." "The types of data varied between portals, including personal information used for COVID-19 contact tracing, COVID-19 vaccination appointments, social security numbers for job applicants, employee IDs, and millions of names and email addresses," UpGuard Research team  said  in a disclosure made public on Monday. Governmental bodies like Indiana, Maryland, and New York City, and private companies such as American Airlines, Ford, J.B. Hunt, and Microsoft are said to have been impacted. Among the most sensitive information that was left in the open were 332,000 email addresses and employee IDs used by Microsoft's own global payroll services, as well as more than 85,000 records related to Business Tools Support and Mixed Reality portals. Power Apps  is ...

One of the great resources available to businesses today is the large ecosystem of value-added services and solutions. Especially in technology solutions, there is no end to the services of which organizations can avail themselves. In addition, if a business needs a particular solution or service they don't handle in-house, there is most likely a third-party vendor that can take care of that for them. It is highly beneficial for businesses today to access these large pools of third-party resources. However, there can be security challenges for companies using third-party vendors and their services despite the benefits. Let's look at navigating vendor risk management as IT professionals and see how businesses can accomplish this in a highly complex cybersecurity world. How can third-party vendors introduce cybersecurity risks? As mentioned, third-party vendors can be highly beneficial to organizations doing business today. They allow companies to avoid building out technolo...

ShinyHunters, a notorious cybercriminal underground group that's been on a data breach spree since last year, has been observed searching companies' GitHub repository source code for vulnerabilities that can be abused to stage larger scale attacks, an analysis of the hackers' modus operandi has revealed. "Primarily operating on Raid Forums, the collective's moniker and motivation can partly be derived from their avatar on social media and other forums: a shiny Umbreon Pokémon," Intel 471 researchers said in a report shared with The Hacker News. "As Pokémon players hunt and collect "shiny" characters in the game, ShinyHunters collects and resells user data." The revelation comes as the  average cost of a data breach  rose from $3.86 million to $4.24 million, making it the highest average cost in 17 years, with compromised credentials responsible for 20% of the breaches reported by over 500 organizations. Since rising to prominence in A...

Close to 14 million Linux-based systems are directly exposed to the Internet, making them a lucrative target for an array of real-world attacks that could result in the deployment of malicious web shells, coin miners, ransomware, and other trojans. That's according to an in-depth look at the Linux threat landscape published by U.S.-Japanese cybersecurity firm Trend Micro , detailing the top threats and vulnerabilities affecting the operating system in the first half of 2021, based on data amassed from honeypots, sensors, and anonymized telemetry. The company, which detected nearly 15 million malware events aimed at Linux-based cloud environments, found coin miners and ransomware to make up 54% of all malware, with web shells accounting for a 29% share. In addition, by dissecting over 50 million events reported from 100,000 unique Linux hosts during the same time period, the researchers found 15 different security weaknesses that are known to be actively exploited in the wild o...

The U.S. Cybersecurity and Infrastructure Security Agency is warning of active exploitation attempts that leverage the latest line of " ProxyShell " Microsoft Exchange vulnerabilities that were patched earlier this May, including deploying LockFile ransomware on compromised systems. Tracked as CVE-2021-34473, CVE-2021-34523, and CVE-2021-31207, the vulnerabilities enable adversaries to bypass ACL controls, elevate privileges on the Exchange PowerShell backend, effectively permitting the attacker to perform unauthenticated, remote code execution. While the former two were addressed by Microsoft on April 13, a patch for CVE-2021-31207 was shipped as part of the Windows maker's May Patch Tuesday updates. "An attacker exploiting these vulnerabilities could execute arbitrary code on a vulnerable machine," CISA  said . The development comes a little over a week after cybersecurity researchers sounded the alarm on  opportunistic scanning and exploitation  of unpat...

Web infrastructure and website security company Cloudflare on Thursday disclosed that it mitigated the largest ever volumetric distributed denial of service (DDoS) attack recorded to date. The attack, launched via a Mirai botnet, is said to have targeted an unnamed customer in the financial industry last month. "Within seconds, the botnet bombarded the Cloudflare edge with over 330 million attack requests," the company  noted , at one point reaching a record high of 17.2 million requests-per-second (rps), making it three times bigger than previously reported HTTP DDoS attacks. Volumetric DDoS attacks are designed to target a specific network with an intention to overwhelm its bandwidth capacity and often utilize  reflective amplification techniques  to scale their attack and cause as much operational disruption as possible. They also typically originate from a network of malware-infected systems — consisting of computers, servers, and IoT devices — enabling threat ac...

ShadowPad, an infamous Windows backdoor that allows attackers to download further malicious modules or steal data, has been put to use by five different Chinese threat clusters since 2017. "The adoption of ShadowPad significantly reduces the costs of development and maintenance for threat actors," SentinelOne researchers Yi-Jhen Hsieh and Joey Chen  said  in a detailed overview of the malware, adding "some threat groups stopped developing their own backdoors after they gained access to ShadowPad." The American cybersecurity firm dubbed ShadowPad a "masterpiece of privately sold malware in Chinese espionage." A successor to PlugX and a modular malware platform since 2015,  ShadowPad  catapulted to widespread attention in the wake of supply chain incidents targeting  NetSarang ,  CCleaner , and  ASUS , leading the operators to shift tactics and update their defensive measures with advanced anti-detection and persistence techniques. More recently, ...

A Nigerian threat actor has been observed attempting to recruit employees by offering them to pay $1 million in bitcoins to deploy Black Kingdom ransomware on companies' networks as part of an insider threat scheme. "The sender tells the employee that if they're able to deploy ransomware on a company computer or Windows server, then they would be paid $1 million in bitcoin, or 40% of the presumed $2.5 million ransom," Abnormal Security  said  in a report published Thursday. "The employee is told they can launch the ransomware physically or remotely. The sender provided two methods to contact them if the employee is interested—an Outlook email account and a Telegram username." Black Kingdom, also known as DemonWare and DEMON, attracted attention earlier this March when threat actors were found  exploiting ProxyLogon flaws  impacting Microsoft Exchange Servers to infect unpatched systems with the ransomware strain. Abnormal Security, which detected and bl...

Mozi, a peer-to-peer (P2P) botnet known to target IoT devices, has gained new capabilities that allow it to achieve persistence on network gateways manufactured by Netgear, Huawei, and ZTE, according to latest findings. "Network gateways are a particularly juicy target for adversaries because they are ideal as initial access points to corporate networks," researchers at Microsoft Security Threat Intelligence Center and Section 52 at Azure Defender for IoT  said  in a technical write-up. "By infecting routers, they can perform man-in-the-middle (MITM) attacks—via HTTP hijacking and DNS spoofing—to compromise endpoints and deploy ransomware or cause safety incidents in OT facilities." First  documented  by Netlab 360 in December 2019, Mozi has a history of infecting routers and digital video recorders in order to assemble them into an IoT botnet, which could be abused for launching distributed denial-of-service (DDoS) attacks, data exfiltration, and payload execut...

A critical vulnerability in Cisco Small Business Routers will not be patched by the networking equipment giant, since the devices reached end-of-life in 2019. Tracked as CVE-2021-34730 (CVSS score: 9.8), the issue resides in the routers' Universal Plug-and-Play (UPnP) service, enabling an unauthenticated, remote attacker to execute arbitrary code or cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability, which the company said is due to improper validation of incoming UPnP traffic, could be abused to send a specially-crafted UPnP request to an affected device, resulting in remote code execution as the root user on the underlying operating system. "Cisco has not released and will not release software updates to address the vulnerability," the company  noted  in an advisory published Wednesday. "The Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers have  entered the end-of-life process . ...

Cybersecurity researchers have disclosed details about an early development version of a nascent ransomware strain called Diavol that has been linked to threat actors behind the infamous TrickBot syndicate. The latest  findings  from IBM X-Force show that the ransomware sample shares similarities to other malware that has been attributed to the cybercrime gang, thus establishing a clearer connection between the two. In early July, Fortinet  revealed  specifics of an unsuccessful ransomware attack involving Diavol payload targeting one of its customers, highlighting the malware's source code overlaps with that of Conti and its technique of reusing some language from Egregor ransomware in its ransom note. "As part of a rather unique encryption procedure, Diavol operates using user-mode Asynchronous Procedure Calls (APCs) without a symmetric encryption algorithm," Fortinet researchers previously said. "Usually, ransomware authors aim to complete the encryption oper...

A security vulnerability has been found affecting several versions of ThroughTek Kalay P2P Software Development Kit (SDK), which could be abused by a remote attacker to take control of an affected device and potentially lead to remote code execution. Tracked as CVE-2021-28372 (CVSS score: 9.6) and  discovered  by FireEye Mandiant in late 2020, the weakness concerns an improper access control flaw in ThroughTek point-to-point (P2P) products, successful exploitation of which could result in the "ability to listen to live audio, watch real time video data, and compromise device credentials for further attacks based on exposed device functionality." "Successful exploitation of this vulnerability could permit remote code execution and unauthorized access to sensitive information, such as to camera audio/video feeds," the U.S. Cybersecurity and Infrastructure Security Agency (CISA)  noted  in an advisory. There are believed to be 83 million active devices on the Kala...
