For the very first time, security researchers have discovered an effective way to exploit a four-year-old hacking technique called Rowhammer to hijack an Android phone remotely. Dubbed GLitch , the proof-of-concept technique is a new addition to the Rowhammer attack series which leverages embedded graphics processing units (GPUs) to carry out a Rowhammer attack against Android smartphones. Rowhammer is a problem with recent generation dynamic random access memory (DRAM) chips in which repeatedly accessing a row of memory can cause "bit flipping" in an adjacent row, allowing anyone to change the value of contents stored in computer memory. Known since at least 2012, the issue was first exploited by Google's Project Zero researchers in early 2015, when they pulled off remote Rowhammer attacks on computers running Windows and Linux. Last year, a team of researchers in the VUSec Lab at Vrije Universiteit Amsterdam demonstrated that the Rowhammer technique could ...

Twitter is urging all of its 330 million users to change their passwords after a software glitch unintentionally exposed its users' passwords by storing them in readable text on its internal computer system. The social media network disclosed the issue in an official blog post and a series of tweets from Twitter Support. According to Twitter CTO Parag Agrawal, Twitter hashes passwords using a popular function known as bcrypt, which replaces an actual password with a random set of numbers and letters and then stored it in its systems. This allows the company to validate users' credentials without revealing their actual passwords, while also masking them in a way that not even Twitter employees can see them. However, a software bug resulted in passwords being written to an internal log before completing the hashing process—meaning that the passwords were left exposed on the company's internal system. Parag said Twitter had found and resolved the problem itsel...

Happy 'World Password Day'! Today is a good time for you to audit your password practices and stop using terrible passwords to protect your online accounts. Experts advice that: Your password must—be long Your password must—be unpredictable Your password must—have at least one number Your password must—not have any dictionary word Your password must—have upper and lowercase letters Your password must—have at least one special character Your password must—be unique and different for every site OK, got it. But who the hell can remember such complex passwords and that too for every [redacted] different site? But don't worry. If you are sick of having to remember dozens of different passwords for dozens of various websites, a great solution is to use a good password manager . Password Manager can significantly reduce the pain to remember every password, along with eliminating for your bad habit of setting a weak password and re-using that same password ever...

While phishing and ransomware dominate headlines, another critical risk quietly persists across most enterprises: exposed Git repositories leaking sensitive data. A risk that silently creates shadow access into core systems Git is the backbone of modern software development, hosting millions of repositories and serving thousands of organizations worldwide. Yet, amid the daily hustle of shipping code, developers may inadvertently leave behind API keys, tokens, or passwords in configuration files and code files, effectively handing attackers the keys to the kingdom. This isn't just about poor hygiene; it's a systemic and growing supply chain risk. As cyber threats become more sophisticated, so do compliance requirements. Security frameworks like NIS2, SOC2, and ISO 27001 now demand proof that software delivery pipelines are hardened and third-party risk is controlled. The message is clear: securing your Git repositories is no longer optional, it's essential. Below, we look at the ris...

Just a few days prior to its monthly patch release, Microsoft released an emergency patch for a critical vulnerability in the Windows Host Compute Service Shim (hcsshim) library that could allow remote attackers to run malicious code on Windows computers. Windows Host Compute Service Shim (hcsshim) is an open source library that helps "Docker for Windows" execute Windows Server containers using a low-level container management API in Hyper-V. Discovered by Swiss developer and security researcher Michael Hanselmann , the critical vulnerability (tracked as CVE-2018-8115) is the result of the failure of the hcsshim library to properly validate input when importing a Docker container image. This, in turn, allows an attacker to remotely execute arbitrary code on the Windows host operating system, eventually letting the attacker create, remove, and replace files on the target host. As Hanselmann explained  in his personal blog, "Importing a Docker container image or...
