Even after so many efforts by Google like launching bug bounty program and preventing apps from using Android accessibility services , malicious applications somehow manage to get into Play Store and infect people with malicious software. The same happened once again when security researchers discovered at least 85 applications in Google Play Store that were designed to steal credentials from users of Russian-based social network VK.com and were successfully downloaded millions of times. The most popular of all masqueraded as a gaming app with more than a million downloads. When this app was initially submitted in March 2017, it was just a gaming app without any malicious code, according to a blog post published Tuesday by Kaspersky Lab. However, after waiting for more than seven months, the malicious actors behind the app updated it with information-stealing capabilities in October 2017. Besides this gaming app, the Kaspersky researchers found 84 such apps on Google Play ...

A 19-year-old vulnerability has been re-discovered in the RSA implementation from at least 8 different vendors—including F5, Citrix, and Cisco—that can give man-in-the-middle attackers access to encrypted messages. Dubbed ROBOT ( Return of Bleichenbacher's Oracle Attack ), the attack allows an attacker to perform RSA decryption and cryptographic operations using the private key configured on the vulnerable TLS servers. ROBOT attack is nothing but a couple of minor variations to the old Bleichenbacher attack on the RSA encryption protocol. First discovered in 1998 and named after Swiss cryptographer Daniel Bleichenbacher, the Bleichenbacher attack is a padding oracle attack on RSA-based PKCS#1 v1.5 encryption scheme used in SSLv2. Leveraging an adaptive chosen-ciphertext attack which occurred due to error messages by SSL servers for errors in the PKCS #1 1.5 padding, Bleichenbacher attack allows attackers to determine whether a decrypted message is correctly padded. ...

Hackers always first go for the weakest link to quickly gain access to your online accounts. Online users habit of reusing the same password across multiple services gives hackers opportunity to use the credentials gathered from a data breach to break into their other online accounts. Researchers from security firm 4iQ have now discovered a new collective database on the dark web (released on Torrent as well) that contains a whopping 1.4 billion usernames and passwords in clear text. The aggregate database, found on 5 December in an underground community forum, has been said to be the largest ever aggregation of various leaks found in the dark web to date, 4iQ founder and chief technology officer Julio Casal noted in a blog post. Though links to download the collection were already circulating online over dark-web sites from last few weeks, it took more exposure when someone posted it on Reddit a few days ago, from where we also downloaded a copy and can now verify its auth...

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 -...

As promised last week , Google's Project Zero researcher Ian Beer now publicly disclosed an exploit that works on almost all 64-bit Apple devices running iOS 11.1.2 or earlier, which can be used to build an iOS jailbreak, allowing users to run apps from non-Apple sources. On Monday morning, Beer shared the details on the exploit, dubbed "tfp0," which leveraged double-free memory corruption vulnerabilities in the kernel, the core of the operating system. Here, " tfp0 " stands for " task for pid 0 " or the kernel task port—which gives users full control over the core of the operating system. The Project Zero researcher responsibly reported these vulnerabilities to Apple in October, which were patched by the company with the release of iOS 11.2 on 2nd December. While Beer says he has successfully tested his proof of concept exploit on the iPhone 6s and 7, and iPod Touch 6G, he believes that his exploit should work on all 64-bit Apple devices. ...

Security researchers have uncovered a previously undetected group of Russian-speaking hackers that has silently been targeting Banks, financial institutions, and legal firms, primarily in the United States, UK, and Russia. Moscow-based security firm Group-IB published a 36-page report on Monday, providing details about the newly-disclosed hacking group, dubbed MoneyTaker , which has been operating since at least May 2016. In the past 18 months, the hacking group is believed to have conducted more than 20 attacks against various financial organisations—stolen more than $11 Million and sensitive documents that could be used for next attacks. According to the security firm, the group has primarily been targeting card processing systems, including the AWS CBR (Russian Interbank System) and SWIFT international bank messaging service (United States). " Criminals stole documentation for OceanSystems' FedLink card processing system, which is used by 200 banks in Latin America...

Here we are with our weekly roundup, briefing this week's top cybersecurity threats, incidents, and challenges, just in case you missed any of them. Last week has been very short with big news from the theft of over 4,700 Bitcoins from the largest cryptocurrency mining marketplace to the discovery of a new malware evasion technique that works on all versions of Microsoft's Windows operating system. Besides this, the newly discovered Janus vulnerability in the Android operating system and a critical remote code execution (RCE) vulnerability in Malware Protection Engine (MPE) for which Microsoft released an emergency patch made their places in our weekly roundup. I recommend you to read the entire news (just click 'Read More' because there's some valuable advice in there as well). So, here we go with the list of this Week's Top Stories: Process Doppelgänging: New Malware Evasion Technique A team of researchers, who previously discovered AtomBombing...
