Cybersecurity researchers have released an updated version of GandCrab ransomware decryption tool that could allow millions of affected users to unlock their encrypted files for free without paying a ransom to the cybercriminals. GandCrab is one of the most prolific families of ransomware to date that has infected over 1.5 million computers since it first emerged in January 2018. Created by BitDefender, the new GandCrab decryption tool [ download ] can now unlock files encrypted by the latest versions of the ransomware, from 5.0 to 5.2, as well as for the older GandCrab ransomware versions. As part of the " No More Ransom " Project, BitDefender works in partnership with the FBI, Europol, London Police, and several other law enforcement agencies across the globe to help ransomware affected users. The cybersecurity company in recent months released ransomware removal tools for some older GandCrab versions that helped nearly 30,000 victims recover their data for free,...

Cybersecurity researchers discover a critical flaw in the popular Evernote Chrome extension that could have allowed hackers to hijack your browser and steal sensitive information from any website you accessed. Evernote is a popular service that helps people taking notes and organize their to-do task lists, and over 4,610,000 users have been using its Evernote Web Clipper Extension for Chrome browser. Discovered by Guardio, the vulnerability ( CVE-2019-12592 ) resided in the ways Evernote Web Clipper extension interacts with websites, iframes and inject scripts, eventually breaking the browser's same-origin policy (SOP) and domain-isolation mechanisms. According to researchers, the vulnerability could allow an attacker-controlled website to execute arbitrary code on the browser in the context of other domains on behalf of users, leading to a Universal Cross-site Scripting (UXSS or Universal XSS) issue. "A full exploit that would allow loading a remote hacker contr...

Telegram, one of the most popular encrypted messaging app, briefly went offline yesterday for hundreds of thousands of users worldwide after a powerful distributed denial-of-service (DDoS) attack hit its servers. Telegram founder Pavel Durov later revealed that the attack was mainly coming from the IP addresses located in China, suggesting the Chinese government could be behind it to sabotage Hong Kong protesters. Since last week, millions of people in Hong Kong are fighting their political leaders over the proposed amendments to an extradition law that would allow a person arrested in Hong Kong to face trial elsewhere, including in mainland China. Many people see it as a fundamental threat to the territory's civic freedoms and the rule of law. Many people in Hong Kong are currently using Telegram's encrypted messaging service to communicate without being spied on, organize the protest, and alert each other about activities on the ground. According to Telegram, th...

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 -...

Real-time visibility into IT assets and activities introduces speed and efficiency to many critical productivity and security tasks organizations are struggling with—from conventional asset inventory reporting to proactive elimination of exposed attack surfaces. However, gaining such visibility is often highly resource consuming and entails manual integration of various feeds. Cynet is now offering end-users and service providers free access to its end-to-end visibility capabilities . The offering consists of 14 days access to the Cynet 360 platform, during which users can gain full visibility into their IT environment—host configurations, installed software, user account activities, password hygiene, and network traffic. "When we built the Cynet 360 platform we identified a critical need for a single-source-of-truth interface where you get all the knowledge regarding what exists in the environment and what activities take place there," said Eyal Gruner, Cynet fou...

In April this year, a software update from Google overnight turned all Android phones , running Android 7.0 Nougat and up, into a FIDO-certified hardware security key as part of a push to encourage two-step verification. The feature made it possible for users to confirm their identity when logging into a Google account more effortless and secure, without separately managing and plugging-in a Yubico's YubiKey or Google's Titan key . "FIDO security keys provide the strongest protection against automated bots, bulk phishing, and targeted attacks by leveraging public key cryptography to verify your identity and URL of the login page, so that an attacker can't access your account even if you are tricked into providing your username and password," Google said . Android's security key feature until now was only compatible with Bluetooth-enabled Chrome OS, macOS, or Windows 10 devices over the Chrome browser. However, the latest update from Google now allow...

A new threat has hit head the headlines ( Robinhood anyone?), and you need to know if you're protected right now. What do you do? Traditionally, you would have to go with one of the options below. Option 1 – Manually check that IoCs have been updated across your security controls. This would require checking that security controls such as your email gateway, web gateway, and endpoint security have all been updated with the latest threats' indicators of compromise (IoCs) usually published by AV companies who detect the malware binaries first. Option 2 – Create a 'carbon copy' of your network and run the threat's binary on that copy. While safe, IT and security teams may be unaware of certain variations from the real deal. So while the attack simulation is running against an 'ideal' copy, your real network may have undergone inadvertent changes, such as a firewall running in monitoring mode, a patch not being installed on time, and other unintent...

A team of cybersecurity researchers yesterday revealed details of a new side-channel attack on dynamic random-access memory (DRAM) that could allow malicious programs installed on a modern system to read sensitive memory data from other processes running on the same hardware. Dubbed RAMBleed and identified as CVE-2019-0174 , the new attack is based on a well-known class of DRAM side channel attack called Rowhammer , various variants [ GLitch , RAMpage , Throwhammer ,  Nethammer , Drammer ] of which have been demonstrated by researchers in recent years. Known since 2012, Rowhammer bug is a hardware reliability issue that was found in the new generation of DRAM chips. It turned out that repeatedly and rapidly accessing (hammering) a row of memory can cause bit flips in adjacent rows, i.e., changing their bit values from 0 to 1 or vice-versa. In the following years, researchers also demonstrated successful exploits to achieve privilege escalation on the vulnerable computers...
