Many companies rely on Endpoint Detection and Response (EDR) solutions as their primary security tool to protect their organizations against cyber threats. EDR was introduced around eight years ago, and analysts now peg the EDR market size as $1.5 to $2.0 billion in annual revenue globally, expecting it to quadruple over the next five years. The recent introduction of Extended Detection and Response (XDR) solutions, however, will certainly cut into a significant portion of that spend. A new provocative eBook: " 5 Questions to Determine: Is Your EDR Providing the Best Bang for Your Buck?"  ( Download here ) helps security executives who currently use an EDR solution determine if they're continuing to get their "bang for the buck" from their EDR provider when compared to newer, equally-priced technologies as XDR. It's also an excellent resource for companies who are in the steps of choosing an EDR solution to deploy. A live webinar around the same topic wi

Efforts to disrupt TrickBot may have  shut down  most of its critical infrastructure, but the operators behind the notorious malware aren't sitting idle. According to new findings shared by cybersecurity firm  Netscout , TrickBot's authors have moved portions of their code to Linux in an attempt to widen the scope of victims that could be targeted. TrickBot, a financial Trojan first detected in 2016, has been traditionally a Windows-based crimeware solution, employing different modules to perform a wide range of malicious activities on target networks, including credential theft and perpetrate ransomware attacks. But over the past few weeks, twin efforts led by the US Cyber Command and Microsoft have helped to  eliminate 94%  of TrickBot's command-and-control (C2) servers that were in use and the new infrastructure the criminals operating TrickBot attempted to bring online to replace the previously disabled servers. Despite the steps taken to impede TrickBot, Microsof

In today's digital world, where connectivity is rules all, endpoints serve as the gateway to a business's digital kingdom. And because of this, endpoints are one of hackers' favorite targets.  According to the IDC,  70% of successful breaches start at the endpoint . Unprotected endpoints provide vulnerable entry points to launch devastating cyberattacks. With IT teams needing to protect more endpoints—and more kinds of endpoints—than ever before, that perimeter has become more challenging to defend. You need to improve your endpoint security, but where do you start? That's where this guide comes in.  We've curated the top 10 must-know endpoint security tips that every IT and security professional should have in their arsenal. From identifying entry points to implementing EDR solutions, we'll dive into the insights you need to defend your endpoints with confidence.  1. Know Thy Endpoints: Identifying and Understanding Your Entry Points Understanding your network's

Google has stepped in to remove several Android applications from the official Play Store following the disclosure that the apps in question were found to serve intrusive ads. The findings were  reported  by the Czech cybersecurity firm Avast on Monday, which said the 21 malicious apps (list  here ) were downloaded nearly eight million times from Google's app marketplace. The apps masqueraded as harmless gaming apps and came packed with  HiddenAds  malware, a notorious Trojan known for its capabilities to serve intrusive ads outside of the app. The group behind the operation relies on social media channels to lure users into downloading the apps. Earlier this June, Avast discovered a  similar HiddenAds campaign  involving 47 gaming apps with over 15 million downloads that were leveraged to display device-wide intrusive ads. "Developers of adware are increasingly using social media channels, like regular marketers would," Avast's Jakub Vávra said. "This time

Cybersecurity researchers over the weekend disclosed new security risks associated with link previews in popular messaging apps that cause the services to leak IP addresses, expose links sent via end-to-end encrypted chats, and even unnecessarily download gigabytes of data stealthily in the background. "Links shared in chats may contain private information intended only for the recipients," researchers Talal Haj Bakry and Tommy Mysk  said . "This could be bills, contracts, medical records, or anything that may be confidential." "Apps that rely on servers to generate link previews may be violating the privacy of their users by sending links shared in a private chat to their servers." Generating Link Previews at the Sender/Receiver Side Link previews are a common feature in most chat apps, making it easy to display a visual preview and a brief description of the shared link. Although apps like  Signal  and  Wire  give users the option to turn on/off l

Microsoft, in collaboration with MITRE, IBM, NVIDIA, and Bosch, has released a  new open framework  that aims to help security analysts detect, respond to, and remediate adversarial attacks against machine learning (ML) systems. Called the  Adversarial ML Threat Matrix , the initiative is an attempt to organize the different techniques employed by malicious adversaries in subverting ML systems. Just as artificial intelligence (AI) and ML are being deployed in a wide variety of novel applications, threat actors can not only  abuse the technology  to power their malware but can also leverage it to  fool machine learning models  with poisoned datasets, thereby causing beneficial systems to make incorrect decisions, and pose a threat to stability and safety of AI applications. Indeed, ESET researchers last year found  Emotet  — a notorious  email-based malware  behind several botnet-driven spam campaigns and ransomware attacks — to be using ML to improve its targeting. Then earlier t

Attention readers, if you are using Google Chrome browser on your Windows, Mac, or Linux computers, you need to update your web browsing software immediately to the latest version Google released earlier today. Google released Chrome version 86.0.4240.111 today to patch several security high-severity issues, including a zero-day vulnerability that has been exploited in the wild by attackers to hijack targeted computers. Tracked as CVE-2020-15999 , the actively exploited vulnerability is a type of memory-corruption flaw called heap buffer overflow in Freetype, a popular open source software development library for rendering fonts that comes packaged with Chrome. The vulnerability was discovered and reported by security researcher Sergei Glazunov of Google Project Zero on October 19 and is subject to a seven-day public disclosure deadline due to the flaw being under active exploitation. Glazunov also immediately reported the zero-day vulnerability to FreeType developers, who then

Graphic for illustration Cybersecurity researchers on Tuesday  disclosed details  about an address bar spoofing vulnerability affecting multiple mobile browsers, such as Apple Safari and Opera Touch, leaving the door open for spear-phishing attacks and delivering malware. Other impacted browsers include UCWeb, Yandex Browser, Bolt Browser, and RITS Browser. The flaws were discovered by Pakistani security researcher Rafay Baloch in the summer of 2020 and jointly reported by Baloch and cybersecurity firm  Rapid7  in August before they were addressed by the browser makers over the past few weeks. UCWeb and Bolt Browser remain unpatched as yet, while Opera Mini is expected to receive a fix on November 11, 2020. The issue stems from using malicious executable JavaScript code in an arbitrary website to force the browser to update the address bar while the page is still loading to another address of the attacker's choice.

A Windows-based remote access Trojan believed to be designed by Pakistani hacker groups to infiltrate computers and steal users' data has resurfaced after a two-year span with retooled capabilities to target Android and macOS devices. According to cybersecurity firm Kaspersky, the malware — dubbed " GravityRAT " — now masquerades as legitimate Android and macOS apps to capture device data, contact lists, e-mail addresses, and call and text logs and transmit them to an attacker-controlled server. First documented by the Indian Computer Emergency Response Team (CERT-In) in August 2017 and subsequently by  Cisco Talos  in April 2018, GravityRAT has been known to target Indian entities and organizations via malware-laced Microsoft Office Word documents at least since 2015. Noting that the threat actor developed at least four different versions of the espionage tool, Cisco said, "the developer was clever enough to keep this infrastructure safe, and not have it blackl
