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.
