An Indian security researcher has publicly published a proof-of-concept (PoC) exploit code for a newly discovered flaw impacting Google Chrome and other Chromium-based browsers like Microsoft Edge, Opera, and Brave. Released by Rajvardhan Agarwal, the working  exploit  concerns a remote code execution vulnerability in the V8 JavaScript rendering engine that powers the web browsers. It is believed to be the same flaw demonstrated by Dataflow Security's Bruno Keith and Niklas Baumstark at  Pwn2Own 2021 hacking contest  last week. Keith and Baumstark were awarded $100,000 for leveraging the vulnerability to run malicious code inside Chrome and Edge. According to the screenshot shared by Agarwal, the PoC HTML file, and its associated JavaScript file, can be loaded in a Chromium-based browser to exploit the security flaw and launch the Windows calculator (calc.exe) app. But it's worth noting that the exploit needs to be chained with another flaw that can allow it to escape Chro

Online trading and discount brokerage platform Upstox has become the latest Indian company to suffer a security breach of its systems, resulting in the exposure of sensitive information of approximately 2.5 million users on the dark web. The leaked information includes names, email addresses, dates of birth, bank account information, and about 56 million know your customer (KYC) documents pulled from the company's server. The breach was first disclosed by independent researcher  Rajshekhar Rajaharia  on April 11. It's not immediately clear when the incident occurred. Reacting to the development, the company however said it had recently upgraded its security systems following reports of "unauthorized access into our database" while stressing that users' funds and securities remained protected. As a precaution, besides initiating a secure password reset of users' accounts, Upstox said it restricted access to the impacted database, implying it was a case

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

Behind the strategies and solutions needed to counter today's cyber threats are—dedicated cybersecurity researchers. They spend their lives dissecting code and analyzing incident reports to discover how to stop the bad guys.  But what drives these specialists? To understand the motivations for why these cybersecurity pros do what they do, we decided to talk with cybersecurity analysts from around the world. To get viewpoints from across Europe, Asia, and the Americas, we recently spoke with a team of researchers from Acronis' global network of Cyber Protection Operations Centers (CPOCs):  Candid Wüest , VP of Cyber Protection Research who is based in Switzerland;  Alexander Ivanyuk , Senior Director, Product, and Technology Positioning, who is based in Singapore; and two Cybersecurity Analysts,  Topher Tebow  and  Blake Collins , who are both based in the U.S. The conversation yielded some interesting insights into their views of the world, how they approach cyber threat an

The 2021 spring edition of  Pwn2Own  hacking contest concluded last week on April 8 with a three-way tie between Team Devcore, OV, and Computest researchers Daan Keuper and Thijs Alkemade. A total of $1.2 million was awarded for 16 high-profile exploits over the course of the three-day virtual event organized by the Zero Day Initiative (ZDI). Targets with successful attempts included Zoom, Apple Safari, Microsoft Exchange, Microsoft Teams, Parallels Desktop, Windows 10, and Ubuntu Desktop operating systems. Some of the major highlights are as follows — Using an authentication bypass and a local privilege escalation to completely take over a Microsoft Exchange server, for which the Devcore team netted $200,000 Chaining a pair of bugs to achieve code execution in Microsoft Teams, earning researcher OV $200,000 A zero-click exploit targeting Zoom that employed a three-bug chain to exploit the messenger app and gain code execution on the target system. ($200,000) The exploitation

APKPure, one of the largest alternative app stores outside of the Google Play Store, was infected with malware this week, allowing threat actors to distribute Trojans to Android devices. In a supply-chain attack similar to that of German telecommunications  equipment manufacturer Gigaset , the APKPure client version 3.17.18 is said to have been tampered with in an attempt to trick unsuspecting users into downloading and installing malicious applications linked to the malicious code built into the APKpure app. The development was reported by researchers from  Doctor Web  and  Kaspersky . "This trojan belongs to the dangerous Android.Triada malware family capable of downloading, installing and uninstalling software without users' permission," Doctor Web researchers said. According to Kaspersky, the APKPure version 3.17.18 was tweaked to incorporate an advertisement SDK that acts as a Trojan dropper designed to deliver other malware to a victim's device. "This

A previously undocumented malware downloader has been spotted in the wild in phishing attacks to deploy credential stealers and other malicious payloads. Dubbed " Saint Bot ," the malware is said to have first appeared on the scene in January 2021, with indications that it's under active development. "Saint Bot is a downloader that appeared quite recently, and slowly is getting momentum. It was seen dropping stealers (i.e.  Taurus  Stealer) or further loaders ( example ), yet its design allows [it] to utilize it for distributing any kind of malware," said Aleksandra "Hasherezade" Doniec, a threat intelligence analyst at Malwarebytes . "Furthermore, Saint Bot employs a wide variety of techniques which, although not novel, indicate some level of sophistication considering its relatively new appearance." The infection chain analyzed by the cybersecurity firm begins with a phishing email containing an embedded ZIP file ("bitcoin.zip&qu

For organizations that deal with the defense infrastructure – cybersecurity is more than just a buzzword. Recently the US Department of Defense (DoD) created a new certification process – the Cybersecurity Maturity Model Certificate (CMMC) – to ensure that all its vendors and contractors follow established best cybersecurity practices. For organizations that work along the DoD supply chain, this means adhering to a strict regulatory framework, which can be quite complex. For one, must ensure that cybersecurity processes and practices are aligned with the type and sensitivity of the information that needs to be protected. Even though the model is tiered (from "basic cybersecurity hygiene" to "advanced"), organizations will expend a significant effort to ensure they align with the compliance level appropriate for their contracts. This is why one XDR provider has created a new guide to demonstrate how it helps organizations achieve CMMC compliance ( download the whitepaper here ). T

Networking equipment major Cisco Systems has said it does not plan to fix a critical security vulnerability affecting some of its Small Business routers, instead urging users to replace the devices. The bug, tracked as CVE-2021-1459, is rated with a CVSS score of 9.8 out of 10, and affects RV110W VPN firewall and Small Business RV130, RV130W, and RV215W routers, allowing an unauthenticated, remote attacker to execute arbitrary code on an affected appliance. The flaw, which stems from improper validation of user-supplied input in the web-based management interface, could be exploited by a malicious actor to send specially-crafted HTTP requests to the targeted device and achieve remote code execution. "A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system of the affected device," Cisco  said  in its advisory. Security researcher Treck Zhou has been credited with reporting the vulnerability. Although th

Gigaset has revealed a malware infection discovered in its Android devices was the result of a compromise of a server belonging to an external update service provider. Impacting older smartphone models — GS100, GS160, GS170, GS180, GS270 (plus), and GS370 (plus) series — the malware took the form of multiple  unwanted apps  that were downloaded and installed through a pre-installed system update app. The infections are said to have occurred starting  March 27 . The German manufacturer of telecommunications devices said it took steps to alert the update service provider of the issue, following which further infections were prevented on April 7. "Measures have been taken to automatically rid infected devices of the malware. In order for this to happen the devices must be connected to the internet (WLAN, WiFi or mobile data). We also recommend connecting the devices to their chargers. Affected devices should automatically be freed from the malware within 8 hours," the comp
