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...

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...

The US-CERT today issued advisory warning users of a new dangerous 17-year-old remote code execution vulnerability affecting the PPP daemon (pppd) software that comes installed on almost all Linux based operating systems, as well as powers the firmware of many other networking devices. The affected pppd software is an implementation of Point-to-Point Protocol (PPP) that enables communication and data transfer between nodes, primarily used to establish internet links such as those over dial-up modems, DSL broadband connections, and Virtual Private Networks. Discovered by IOActive security researcher Ilja Van Sprundel , the critical issue is a stack buffer overflow vulnerability that exists due to a logical error in the Extensible Authentication Protocol (EAP) packet parser of the pppd software, an extension that provides support for additional authentication methods in PPP connections. The vulnerability , tracked as CVE-2020-8597  with CVSS Score 9.8, can be exploited by ...

More than 200 million records containing a wide range of property-related information on US residents were left exposed on a database that was accessible on the web without requiring any password or authentication. The exposed data — a mix of personal and demographic details — included the name, address, email address, age, gender, ethnicity, employment, credit rating, investment preferences, income, net worth, and property information, such as: Market value Property type Mortgage amount, rate, type, and lender Refinance amount, rate, type, and lender Previous owners Year built Number of beds and bathrooms Tax assessment information According to security firm Comparitech , the database, which was hosted on Google Cloud, is said to have been first indexed by search engine BinaryEdge on 26th January and discovered a day later by cybersecurity researcher Bob Diachenko. But after failing to identify the database owner, the server was eventually taken offline more than a...

If you are a T-Mobile customer, this news may concern you. US-based telecom giant T-Mobile has suffered yet another data breach incident that recently exposed personal and accounts information of both its employees and customers to unknown hackers. What happened? In a breach notification posted on its website, T-Mobile today said its cybersecurity team recently discovered a sophisticated cyberattack against the email accounts of some of its employees that resulted in unauthorized access to the sensitive information contained in it, including details for its customers and other employees. Although the telecom company did not disclose how the breach happened, when it happened, and exactly how many employees and users were affected, it did confirm that the leaked information on its users doesn't contain financial information like credit card and Social Security numbers. What type of information was accessed? The exposed data of an undisclosed number of affected users incl...

Not happy with your expensive iPhone and wondered if it's possible to run any other operating system on your iPhone, maybe, how to install Android on an iPhone or Linux for iPhones? Android phones can be rooted, and iPhones can be jailbroken to unlock new features, but so far, it's been close to impossible to get Android running on iPhones, given the mobile device hardware constraints and software limitations. However, it's now possible to smoothly run Android on an iPhone—thanks to a new initiative, dubbed Project Sandcastle . Undertaken by cybersecurity startup Corellium , Project Sandcastle is the consequence of a 13-year-long developmental effort to port Android to iOS and as well as demonstrate that Apple's much-vaunted security barriers can indeed be compromised. "Where sandboxes set limits and boundaries, sandcastles provide an opportunity to create something new from the limitless bounds of your imagination," the project website says. "T...

The most popular free certificate signing authority Let's Encrypt is going to revoke more than 3 million TLS certificates within the next 24 hours that may have been issued wrongfully due to a bug in its Certificate Authority software. The bug, which Let's Encrypt confirmed on February 29 and was fixed two hours after discovery, impacted the way it checked the domain name ownership before issuing new TLS certificates. As a result, the bug opened up a scenario where a certificate could be issued even without adequately validating the holder's control of a domain name. The Certification Authority Authorization (CAA), an internet security policy, allows domain name holders to indicate to certificate authorities (CAs) whether or not they are authorized to issue digital certificates for a specific domain name. Let's Encrypt considers domain validation results good only for 30 days from the time of validation, after which it rechecks the CAA record authorizing t...

The RSA Conference , the world's leading information security conference and exposition, held its 29th annual event in San Francisco last week. According to the organizers, over 36,000 attendees, 704 speakers, and 658 exhibitors gathered at the Moscone Center to discuss privacy, Machine Learning, and AI, policy and government, applied crypto and blockchain, and, new for the RSA Conference 2020, open source tools, product security and anti-fraud. Despite several large vendors including Verizon and IBM canceling their presence in light of the spiraling panic around coronavirus, the event was one of the brightest and innovative, according to numerous stakeholders expressing their excitement in the media and on social networks. We decided to gather some feedback from the attendees, journalists, and security experts involved in RSA 2020 to understand the most recent cybersecurity trends after this milestone event. Below is our selection of 10 most innovative cybersecurity com...

Qihoo 360, one of the most prominent cybersecurity firms, today published a new report accusing the U.S. Central Intelligence Agency (CIA) to be behind an 11-year-long hacking campaign against several Chinese industries and government agencies. The targeted industry sectors include aviation organizations, scientific research institutions, petroleum, and Internet companies—which, if true, gives the CIA the ability to do "unexpected things." According to the researchers, these cyberattacks were carried out between September 2008 and June 2019, and most of the targets were located in Beijing, Guangdong, and Zhejiang. "We speculate that in the past eleven years of infiltration attacks, the CIA may have already grasped the most classified business information of China, even of many other countries in the world," the researchers said . "It does not even rule out the possibility that now the CIA is able to track down the real-time global flight status, passe...

At a certain point, almost every organization reaches the conclusion that there is a need to move past just the standard AV and firewall stack in order to soundly protect their environment. The common practice in recent years is to gain extra protection through implementing either EDR\EPP solutions (represented by vendors like Crowdstrike and Carbon Black) or Network Traffic Analysis/NDR solutions (such as Darktrace and Vectra Networks). Fortune 500 companies who have large security teams, would usually choose to buy and implement both. A recently published guide, 'Advanced Threat Protection Beyond the AV' ( download here ) is the first resource that not only guides security executives through the pros and cons of each solution type but also outlines a best-practice approach that allows the "non-Fortune 500" companies to combine the advantages of both approaches – without actually buying both. The proliferation of advanced threats in the decade has gradually ...

Two Chinese nationals have been charged by the US Department of Justice (DoJ) and sanctioned by the US Treasury for allegedly laundering $100 million worth of virtual currency using prepaid Apple iTunes gift cards. According to a newly unsealed court document , the illicit funds originated from a $250 million haul stolen from two different unnamed cryptocurrency exchanges that were perpetrated by Lazarus Group , a cybercrime group with ties with the North Korean government. The two individuals in question — Tian Yinyin (田寅寅)  and Li Jiadong (李家东) — were both charged with operating an unlicensed money transmitting business and money laundering conspiracy. Prosecutors said the defendants worked on behalf of the threat actors based in North Korea to allegedly launder over a $100 million worth of stolen cryptocurrency to obscure transactions, adding the hacking of cryptocurrency exchanges posed a severe threat to the security of the global financial system. It's worth notin...
