Did you know… last month's widespread WannaCry ransomware attack forced Microsoft to release security updates against EternalBlue SMB exploit for unsupported versions of Windows, but the company left other three Windows zero-day exploits unpatched? For those unaware, EternalBlue is a Windows SMB flaw that was leaked by the Shadow Brokers in April and then abused by the WannaCry ransomware to infect nearly 300,000 computers in more than 150 countries within just 72 hours on 12th of May. Shortly after WannaCry outbreak, we reported that three unpatched Windows exploits , codenamed " EsteemAudit, " " ExplodingCan ," and " EnglishmanDentist ," were also being exploited by individuals and state-sponsored hackers in the wild. Specially EsteemAudit , one of the dangerous Windows hacking tool that targets remote desktop protocol (RDP) service on Microsoft Windows Server 2003 and Windows XP machines, while ExplodingCan exploits bugs in IIS 6.0 and E...

In this year's annual event, Apple announced that the company had paid out $70 Billion to developers in the App Store's lifetime and that $21 Billion of the amount was paid in the last year alone. But has all this money gone to the legitimate app developers? Probably not, as app developer Johnny Lin last week analyzed the Apple's App Store and discovered that most of the trending apps on the app store are completely fake and are earning their makers hundreds of thousands of dollars through in-app purchases and subscriptions. Scammers Use 'Search Ads' Platform to Boost App Ranking Shady developers are abusing Apple's relatively new and immature App Store Search Ads, which was launched at last year's Worldwide Developers Conference (WWDC), to promote their app in the store by using a few strategically chosen search ads and a bit of SEO. "They're taking advantage of the fact that there's no filtering or approval process for ads, and ...

Over 800 different Android apps that have been downloaded millions of times from Google Play Store found to be infected with malicious ad library that silently collects sensitive user data and can perform dangerous operations. Dubbed " Xavier ," the malicious ad library, initially emerged in September 2016, is a member of AdDown malware family, potentially posing a severe threat to millions of Android users. Since 90 percent of Android apps are free for anyone to download, advertising on them is a key revenue source for their developers. For this, they integrate Android SDK Ads Library in their apps, which usually doesn't affect an app's core functionality. According to security researchers at Trend Micro , the malicious ad library comes pre-installed on a wide range of Android applications, including photo editors, wallpapers and ringtone changers, Phone tracking, Volume Booster, Ram Optimizer and music-video player. Features of Xavier Info-Stealing Malware...

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 -...

Last December, a cyber attack on Ukrainian Electric power grid caused the power outage in the northern part of Kiev — the country's capital — and surrounding areas, causing a blackout for tens of thousands of citizens for an hour and fifteen minutes around midnight. Now, security researchers have discovered the culprit behind those cyber attacks on the Ukrainian industrial control systems. Slovakia-based security software maker ESET and US critical infrastructure security firm Dragos Inc. say they have discovered a new dangerous piece of malware in the wild that targets critical industrial control systems and is capable of causing blackouts. Dubbed " Industroyer " or " CrashOverRide ," the grid-sabotaging malware was likely to be used in the December 2016 cyber attack against Ukrainian electric utility Ukrenergo , which the security firms say represents a dangerous advancement in critical infrastructure hacking. According to the researchers, CrashO...

WannaCry , the biggest ransomware attack in the history, gained prominence very rapidly in the media globally after the ransomware infected more than 300,000 computers in over 150 countries within just 72 hours. Governments, Intelligence agencies and law enforcement around the world have already started their investigations and are working closely with affected companies to track down hackers responsible for the global cyber attack launched on Friday, 12th May. Some researchers traced back WannaCry to a state-sponsored hacking group in North Korea, while other believed the perpetrators might be Chinese . If you have been following WannaCry coverage on The Hacker News, you should be aware of that the WannaCry ransomware uses Tor hidden service to communicate with its command-and-control server. Just yesterday, we came to know that French authorities had seized at least 6 Tor's entry guard node servers, hosted on France-based hosting providers, just two days after the o...

Remember SambaCry ? Two weeks ago we reported about a 7-year-old critical remote code execution vulnerability in Samba networking software (re-implementation of SMB networking protocol) that allows a remote hacker to take full control of a vulnerable Linux and Unix machines. To know more about the SambaCry vulnerability (CVE-2017-7494) and how it works, you can read our previous article . At that time, nearly 485,000 Samba-enabled computers were found to be exposed on the Internet, and researchers predicted that the SambaCry-based attacks also have potential to spread just like WannaCry ransomware widely. The prediction came out to be quite accurate, as honeypots set up by the team of researchers from Kaspersky Lab have captured a malware campaign that is exploiting SambaCry vulnerability to infect Linux computers with cryptocurrency mining software. Another security researcher, Omri Ben Bassat‏, independently discovered  the same campaign and named it "EternalMiner...

Social media networks are no doubt a quick and powerful way to share information and ideas, but not everything shared on Facebook or Twitter is true. Misinformation, or "Fake News," has emerged as a primary issue for social media platforms, seeking to influence millions of people with wrong propaganda and falsehoods. In past years, we have seen how political parties and other groups have used spoofed social media profiles of influencers or leaders to spread misinformation, and most of the time such techniques work to successfully convince people into believing that the information is true. Although social media services like Facebook, Twitter, and Google, offers account verification (verified accounts with blue tick) for public figures, we have seen hackers hijacking verified accounts to spread fake news from legitimate account to their millions of followers. Now, researchers have uncovered a new, cunning attack technique currently being used by hackers to take ove...

It's not hard for a well-funded state-sponsored hacking group to break into corporate networks and compromise systems with malware, but what's challenging for them is to keep that backdoor and its communication undetectable from a firewall and other network monitoring applications. However, a cyber-espionage group known as " Platinum ," that is actively targeting governmental organisations, defense institutes, and telecommunication providers since at least 2009, has found a way to hide its malicious activities from host-based protection mechanisms. Microsoft has recently discovered that the cyber-espionage group is now leveraging Intel's Active Management Technology (AMT) Serial-over-LAN (SOL) channel as a file-transfer tool to steal data from the targeted computers without detection. Intel-based chip sets come with an embedded technology, called AMT, which is designed to allow IT administrators to remotely manage and repair PCs, workstations, and serve...

Image Source: South China Morning Post Chinese authorities have announced the arrest of around 22 distributors working as Apple distributors as part of a $7 million operation, who stole customers' personal information from an internal Apple database and illegally sold it to Chinese black market vendors. According to a report from Chinese media , this underground network reportedly consisted of employees working in direct Apple suppliers, and other outsource firms in the Zhejiang, a province in eastern China. These employees had access to Apple databases along with other tools containing sensitive information about its customers. They allegedly used their company's internal computer system to gather data includes usernames, email addresses, phone numbers, and Apple IDs, and then sold it in the underground market for between 10 yuan ($1.47) and 80 yuan ($11.78) per data point. So far, the network has made a total of 50 million yuan (around $7.36 million). However, it is ...

A new Android-rooting malware with an ability to disable device' security settings in an effort to perform malicious tasks in the background has been detected on the official Play Store. What's interesting? The app was smart enough to fool Google security mechanism by first pretending itself to be a clean app and then temporarily replacing it with a malicious version. Security researchers at Kaspersky Lab discovered a new piece of Android rooting malware that was being distributed as gaming apps on the Google Play Store, hiding behind puzzle game " colourblock ," which was being downloaded at least 50,000 times prior to its removal. Dubbed Dvmap , the Android rooting malware disables device's security settings to install another malicious app from a third-party source and also injects malicious code into the device system runtime libraries to gain root access and stay persistent. "To bypass Google Play Store security checks, the malware creators used ...

Security researchers have discovered over a dozen of vulnerabilities in tens of thousands of web-connected cameras that can not be protected just by changing their default credentials. Vulnerabilities found in two models of IP cameras from China-based manufacturer Foscam allow attackers to take over the camera, view video feeds, and, in some cases, even gain access to other devices connected to a local network. Researchers at security firm F-Secure discovered 18 vulnerabilities in two camera models — one sold under the Foscam C2 and other under Opticam i5 HD brand — that are still unpatched despite the company was informed several months ago. In addition to the Foscam and Opticam brands, F-Secure also said the vulnerabilities were likely to exist in 14 other brands that use Foscam internals, including Chacon, 7links, Netis, Turbox, Thomson, Novodio, Nexxt, Ambientcam, Technaxx, Qcam, Ivue, Ebode and Sab. The flaws discovered in the IP cameras includes: Insecure default cr...

" Disable macros and always be extra careful when you manually enable it while opening Microsoft Office Word documents. " You might have heard of above-mentioned security warning multiple times on the Internet as hackers usually leverage this decade old macros-based hacking technique to hack computers through specially crafted Microsoft Office files, particularly Word, attached to spam emails. But a new social engineering attack has been discovered in the wild, which doesn't require users to enable macros ; instead it executes malware on a targeted system using PowerShell commands embedded inside a PowerPoint (PPT) file. Moreover, the malicious PowerShell code hidden inside the document triggers as soon as the victim moves/hovers a mouse over a link (as shown), which downloads an additional payload on the compromised machine -- even without clicking it. Researchers at Security firm SentinelOne have discovered that a group of hackers is using malicious PowerPoi...
