A critical security vulnerability has been disclosed in  HAProxy , a widely used open-source load balancer and proxy server, that could be abused by an adversary to possibly smuggle HTTP requests, resulting in unauthorized access to sensitive data and execution of arbitrary commands, effectively opening the door to an array of attacks. Tracked as  CVE-2021-40346 , the Integer Overflow vulnerability has a severity rating of 8.6 on the CVSS scoring system and has been rectified in HAProxy versions 2.0.25, 2.2.17, 2.3.14 and 2.4.4. HTTP Request Smuggling, as the name implies, is a web application attack that tampers the manner a website processes sequences of HTTP requests received from more than one user. Also called HTTP desynchronization, the technique takes advantage of parsing inconsistencies in how front-end servers and back-end servers process requests from the senders. Front-end servers are typically load balancers or reverse proxies that are used by websites to mana...

Cybersecurity researchers on Tuesday released new findings that reveal a year-long mobile espionage campaign against the Kurdish ethnic group to deploy two Android backdoors that masquerade as legitimate apps. Active since at least March 2020, the attacks leveraged as many as six dedicated Facebook profiles that claimed to offer tech and pro-Kurd content — two aimed at Android users while the other four appeared to provide news for the Kurdish supporters — only to share links to spying apps on public Facebook groups. All the six profiles have since been taken down. "It targeted the Kurdish ethnic group through at least 28 malicious Facebook posts that would lead potential victims to download Android 888 RAT or SpyNote," ESET researcher Lukas Stefanko  said . "Most of the malicious Facebook posts led to downloads of the commercial, multi-platform 888 RAT, which has been available on the black market since 2018." The Slovakian cybersecurity firm attributed the at...

Most cyber security today involves much more planning, and much less reacting than in the past. Security teams spend most of their time preparing their organizations' defenses and doing operational work. Even so, teams often must quickly spring into action to respond to an attack. Security teams with copious resources can quickly shift between these two modes. They have enough resources to allocate to respond properly. Lean IT security teams, however, are more hard-pressed to react effectively. A new guide by XDR provider Cynet ( download here ), however, argues that lean teams can still respond effectively. It just takes some work.  For teams that are resource-constrained, success starts with having a clear plan and putting the tools and infrastructure in place for the organization to follow properly. The guide breaks down the tools, factors, and knowledge that go into optimizing an organization's time to respond.  Building a successful incident response plan Today's ...

I had the honor of hosting the first episode of the Xposure Podcast live from Xposure Summit 2025. And I couldn't have asked for a better kickoff panel: three cybersecurity leaders who don't just talk security, they live it. Let me introduce them. Alex Delay , CISO at IDB Bank, knows what it means to defend a highly regulated environment. Ben Mead , Director of Cybersecurity at Avidity Biosciences, brings a forward-thinking security perspective that reflects the innovation behind Avidity's targeted RNA therapeutics. Last but not least, Michael Francess , Director of Cybersecurity Advanced Threat at Wyndham Hotels and Resorts, leads the charge in protecting the franchise. Each brought a unique vantage point to a common challenge: applying Continuous Threat Exposure Management (CTEM) to complex production environments. Gartner made waves in 2023 with a bold prediction: organizations that prioritize CTEM will be three times less likely to be breached by 2026. But here's the kicker -...

Microsoft on Tuesday warned of an actively exploited zero-day flaw impacting Internet Explorer that's being used to hijack vulnerable Windows systems by leveraging weaponized Office documents. Tracked as CVE-2021-40444 (CVSS score: 8.8), the remote code execution flaw is rooted in MSHTML (aka Trident), a proprietary browser engine for the now-discontinued Internet Explorer and which is used in Office to render web content inside Word, Excel, and PowerPoint documents. "Microsoft is investigating reports of a remote code execution vulnerability in MSHTML that affects Microsoft Windows. Microsoft is aware of targeted attacks that attempt to exploit this vulnerability by using specially-crafted Microsoft Office documents," the company  said . "An attacker could craft a malicious ActiveX control to be used by a Microsoft Office document that hosts the browser rendering engine. The attacker would then have to convince the user to open the malicious document. Users who...

The maintainers of Jenkins—a popular open-source automation server software—have disclosed a security breach after unidentified threat actors gained access to one of their servers by exploiting a recently disclosed vulnerability in Atlassian Confluence service to install a cryptocurrency miner. The "successful attack," which is believed to have occurred last week, was mounted against its Confluence service that had been deprecated since October 2019, leading the team to take the server offline, rotate privileged credentials, and reset passwords for developer accounts. "At this time we have no reason to believe that any Jenkins releases, plugins, or source code have been affected," the company  said  in a statement published over the weekend. The disclosure comes as the U.S. Cyber Command  warned  of ongoing mass exploitation attempts in the wild targeting a now-patched critical security vulnerability affecting Atlassian Confluence deployments. Tracked as CVE-2...

End-to-end encrypted email service provider ProtonMail has  drawn   criticism  after it ceded to a legal request and shared the IP address of anti-gentrification activists with law enforcement authorities, leading to their arrests in France. The Switzerland-based company said it received a "legally binding order from the Swiss Federal Department of Justice" related to a collective called Youth for Climate, which it was "obligated to comply with," compelling it to handover the IP address and information related to the type of device used by the group to access the ProtonMail account. On its website, ProtonMail  advertises  that: "No personal information is required to create your secure email account. By default, we do not keep any IP logs which can be linked to your anonymous email account. Your privacy comes first." Protonmail Homepage Despite its no IP logs claims, the company acknowledged that while it's illegal for the company to abide by req...

An ongoing campaign has been found to leverage a network of websites acting as a "dropper as a service" to deliver a bundle of malware payloads to victims looking for "cracked" versions of popular business and consumer applications. "These malware included an assortment of click fraud bots, other information stealers, and even ransomware," researchers from cybersecurity firm Sophos  said  in a report published last week. The attacks work by taking advantage of a number of bait pages hosted on WordPress that contain "download" links to software packages, which, when clicked, redirect the victims to a different website that delivers potentially unwanted browser plug-ins and malware, such as installers for  Raccoon Stealer , Stop ransomware, the Glupteba backdoor, and a variety of malicious cryptocurrency miners that masquerade as antivirus solutions. "Visitors who arrive on these sites are prompted to allow notifications; If they allow th...

Networking, storage and security solutions provider Netgear on Friday  issued patches  to address three security vulnerabilities affecting its smart switches that could be abused by an adversary to gain full control of a vulnerable device. The flaws, which were discovered and reported to Netgear by Google security engineer Gynvael Coldwind, impact the following models - GC108P (fixed in firmware version 1.0.8.2) GC108PP (fixed in firmware version 1.0.8.2) GS108Tv3 (fixed in firmware version 7.0.7.2) GS110TPP (fixed in firmware version 7.0.7.2) GS110TPv3 (fixed in firmware version 7.0.7.2) GS110TUP (fixed in firmware version 1.0.5.3) GS308T (fixed in firmware version 1.0.3.2) GS310TP (fixed in firmware version 1.0.3.2) GS710TUP (fixed in firmware version 1.0.5.3) GS716TP (fixed in firmware version 1.0.4.2) GS716TPP (fixed in firmware version 1.0.4.2) GS724TPP (fixed in firmware version 2.0.6.3) GS724TPv2 (fixed in firmware version 2.0.6.3) GS728TPPv2 (fixed in ...

Apple is temporarily hitting the pause button on its  controversial plans  to screen users' devices for child sexual abuse material (CSAM) after receiving sustained blowback over worries that the tool could be weaponized for mass surveillance and erode the privacy of users. "Based on feedback from customers, advocacy groups, researchers, and others, we have decided to take additional time over the coming months to collect input and make improvements before releasing these critically important child safety features," the iPhone maker  said  in a statement on its website. The announcement, however, doesn't make it clear as to the kind of inputs it would be gathering, the nature of changes it aims to devise, or how it intends to implement the system in a way that mitigates the privacy and security concerns that could arise once it's deployed. The changes were originally slated to go live with iOS 15 and macOS Monterey later this year, starting with the U.S. In ...
