Remember rowhammer vulnerability? A critical issue affecting modern DRAM (dynamic random access memory) chips that could allow attackers to obtain higher kernel privileges on a targeted system by repeatedly accessing memory cells and induce bit flips. To mitigate Rowhammer vulnerability on the latest DDR4 DRAM, many memory chip manufacturers added some defenses under the umbrella term Target Row Refresh (TRR) that refreshes adjacent rows when a victim row is accessed more than a threshold. But it turns out 'Target Row Refresh,' promoted as a silver bullet to mitigate rowhammer attacks, is also insufficient and could let attackers execute new hammering patterns and re-enable the bit-flip attacks on the latest hardware as well. TRRespass: The Rowhammer Fuzzing Tool Tracked as CVE-2020-10255 , the newly reported vulnerability was discovered by researchers at VUSec Lab, who today also released ' TRRespass ,' an open source black box many-sided RowHammer fuzzin...

Microsoft today announced that it has successfully disrupted the botnet network of the Necurs malware, which has infected more than 9 million computers globally, and also hijacked the majority of its infrastructure. The latest botnet takedown was the result of a coordinated operation involving international police and private tech companies across 35 countries. The operation was conducted successfully after researchers successfully broke the domain generation algorithm (DGA) implemented by the Necurs malware, which helped it remain resilient for a long time. DGA is basically a technique to unpredictably generate new domain names at regular intervals, helping malware authors to continuously switch the location of C&C servers and maintain undisrupted digital communication with the infected machines. "We were then able to accurately predict over six million unique domains that would be created in the next 25 months. Microsoft reported these domains to their respective r...

It appears there is no end in sight to the hardware level security vulnerabilities in Intel processors, as well as to the endless 'performance killing' patches that resolve them. Modern Intel CPUs have now been found vulnerable to a new attack that involves reversely exploiting Meltdown-type data leak vulnerabilities to bypass existing defenses, two separate teams of researchers told The Hacker News. Tracked as CVE-2020-0551 , dubbed " Load Value Injection in the Line Fill Buffers" or LVI-LFB for short, the new speculative-execution attack could let a less privileged attacker steal sensitive information—encryption keys or passwords—from the protected memory and subsequently, take significant control over a targeted system. According to experts at Bitdefender and academic researchers from a couple of universities, the new attack is particularly devastating in multi-tenant environments such as enterprise workstations or cloud servers in the datacenter. And...

SaaS Adoption is Skyrocketing, Resilience Hasn't Kept Pace SaaS platforms have revolutionized how businesses operate. They simplify collaboration, accelerate deployment, and reduce the overhead of managing infrastructure. But with their rise comes a subtle, dangerous assumption: that the convenience of SaaS extends to resilience. It doesn't. These platforms weren't built with full-scale data protection in mind . Most follow a shared responsibility model — wherein the provider ensures uptime and application security, but the data inside is your responsibility. In a world of hybrid architectures, global teams, and relentless cyber threats, that responsibility is harder than ever to manage. Modern organizations are being stretched across: Hybrid and multi-cloud environments with decentralized data sprawl Complex integration layers between IaaS, SaaS, and legacy systems Expanding regulatory pressure with steeper penalties for noncompliance Escalating ransomware threats and inside...

A federal judge in New York on Monday declared a mistrial in the case of a former CIA software engineer who was accused of stealing a massive trove of the agency's classified hacking and tools and leaking it to WikiLeaks whistleblower website. While the jury was unable to reach a verdict on eight counts of the theft and transmission of CIA's confidential documents, it did find ex-CIA Joshua Schulte guilty on two counts of contempt of court and making false statements to the FBI investigators. Schulte's lawyers last month asked the court for a mistrial in this case claiming the prosecutors withheld evidence that could exonerate his client during the four-week trial in the Manhattan federal court. Potentially, as a result of this, jurors failed to reach a unanimous agreement on the most severe charges against Schulte after deliberating since last week. Schulte, who designed hacking tools and malware for both the CIA and NSA to break into adversaries computers,...

AMD processors from as early as 2011 to 2019 carry previously undisclosed vulnerabilities that open them to two new different side-channel attacks, according to a freshly published research. Known as " Take A Way ," the new potential attack vectors leverage the L1 data (L1D) cache way predictor in AMD's Bulldozer microarchitecture to leak sensitive data from the processors and compromise the security by recovering the secret key used during encryption. The research was published by a group of academics from the Graz University of Technology and Research Institute of Computer Science and Random Systems (IRISA), who responsibly disclosed the vulnerabilities to AMD back in August 2019. "We are aware of a new white paper that claims potential security exploits in AMD CPUs, whereby a malicious actor could manipulate a cache-related feature to potentially transmit user data in an unintended way," AMD said in an advisory posted on its website over the weekend...

All Intel processors released in the past 5 years contain an unpatchable vulnerability that could allow hackers to compromise almost every hardware-enabled security technology that are otherwise designed to shield sensitive data of users even when a system gets compromised. The vulnerability, tracked as CVE-2019-0090 , resides in the hard-coded firmware running on the ROM ("read-only memory") of the Intel's Converged Security and Management Engine (CSME), which can't be patched without replacing the silicon. Intel CSME is a separate security micro-controller incorporated into the processors that provides an isolated execution environment protected from the host opening system running on the main CPU. It is responsible for the initial authentication of Intel-based systems by loading and verifying firmware components, root of trust based secure boot, and also cryptographically authenticates the BIOS, Microsoft System Guard, BitLocker, and other security features...

On the same day yesterday, when the US-based telecom giant T-Mobile admitted a data breach , the UK-based telecommunication provider Virgin Media announced that it has also suffered a data leak incident exposing the personal information of roughly 900,000 customers. What happened? Unlike the T-Mobile data breach that involved a sophisticated cyber attack, Virgin Media said the incident was neither a cyber attack nor the company's database was hacked. Rather the personal details of around 900,000 Virgin Media UK-based customers were exposed after one of its marketing databases was left unsecured on the Internet and accessible to anyone without requiring any authentication. "The precise situation is that information stored on one of our databases has been accessed without permission. The incident did not occur due to a hack, but as a result of the database being incorrectly configured," the company said in a note published on its website on Thursday night. Acc...
