Western Digital Extends Storage Leadership with Bics5 3D NAND Technology

Western Digital Corp. has announced that it has successfully developed its fifth-generation 3D NAND technology, BiCS5, continuing the company’s leadership in delivering the industry’s most advanced flash memory technologies.
BiCS5, built on triple-level-cell (TLC) and quad-level-cell (QLC) technologies, delivers exceptional capacity, performance and reliability at a compelling cost. This makes it ideal to address the exponential growth of data associated with connected cars, mobile devices and artificial intelligence.
Western Digital has commenced initial production of BiCS5 TLC in a 512-gigabit (Gb) chip and is currently shipping consumer products built on the new technology. Production of BiCS5 in meaningful commercial volumes is expected in the second half of calendar 2020. BiCS5 TLC and BiCS5 QLC will be available in a range of capacities, including 1.33 terabit (Tb).
“As we move into the next decade, a new approach to 3D NAND scaling is critical to continuing to meet the demands of the rising volume and velocity of data,” said Dr. Steve Paak, senior vice president of memory technology and manufacturing at Western Digital. “Our successful production of BiCS5 is an illustration of Western Digital’s ongoing leadership in flash memory technology and strong execution to our roadmap.
By leveraging new advancements to our multi-tier memory hole technology to increase density laterally as well as adding more storage layers, we have significantly scaled the capacity and performance of our 3D NAND technology, while continuing to deliver the reliability and cost which our customers expect.”
Built utilizing a wide range of new technology and manufacturing innovations, BiCS5 is Western Digital’s highest density and most advanced 3D NAND technology to date. Second-generation multi-tier memory hole technology, improved engineering processes and other 3D NAND cell enhancements significantly increase cell array density horizontally across the wafer.
These “lateral scaling” advancements in combination with 112 layers of vertical memory capability enables BiCS5 to offer up to 40 percent* more bits of storage capacity per wafer compared to Western Digital’s 96-layer BiCS4 technology, while optimizing cost. New design enhancements also accelerate performance, enabling BiCS5 to offer up to 50 percent faster I/O performance compared to BiCS4.
BiCS5 technology was developed jointly with technology and manufacturing partner Kioxia Corporation. It will be manufactured at the joint venture fabrication facilities in Yokkaichi in Mie Prefecture, Japan and Kitakami City, Iwate Prefecture, Japan.
The introduction of BiCS5 technology builds on a full portfolio of Western Digital 3D NAND technologies for use in data-centric personal electronics, smartphones, IoT devices and data centers.

FG Launches Online Visa Approval Centre

Dr. Olubunmi Tunji-Ojo, minister of Interior, has announced the launch of an Online Visa Approval Center to eliminate bureaucratic bottlenecks and reduce corruption in the visa application process.
Commissioned by the President in December, the new system ensures that applicants no longer need to visit a visa office, know anyone in the system, or lobby for approvals.
At a stakeholders’ sensitisation workshop on the implementation of the Nigeria Visa Policy (NVP) 2025, yesterday in Abuja, Dr. Tunji-Ojo said the visa is considered a very important document by the government because it is an instrument of migration management and an instrument of economic development.
The minister explained that Nigeria has to strike a delicate balance between national security and, of course, the ease of migration.
“And we think that it’s something that we can do and something we will do.
“We don’t have a physical Visa Approval Center. If you apply for a Nigerian visa anywhere in the world, you do so online. We process it here in Nigeria, and if approved, you receive your e-visa in your email,” he explained.
To enhance efficiency, the government has set a 48-hour deadline for processing e-visas.
“It is unprofessional and unacceptable for the Nigeria Immigration Service not to approve or provide feedback within 48 hours,” the minister stated.
“It breaks my heart that people need to lobby to even get visas to Nigeria. It shouldn’t be so. It shouldn’t be.
“For anybody that is qualified, for anybody that wants to do legitimate activities in Nigeria, such people should be able to come to Nigeria easily. And this is why we are opening our space. Mr. President is interested in foreign direct investments.”
Further, he said Nigeria is interested in partnering with the rest of the world to develop its economy but, “We can’t do that when we allow bottlenecks to hold us down. So these reforms, basically, are aimed at opening our space, enhancing national security, and we hope that the primary responsibilities of the visa scheme will be achieved.”
Kemi Nandap, controller general, Nigeria Immigration Service (NIS), said the NIS would fully digitize its e-visa platform and reduce visa classifications from 79 to 44 to enhance accessibility, transparency, and efficiency in the new visa policy.
She said, “At the core of this policy is the new e-visa platform—a fully digitized, centralized system that revolutionizes how foreign nationals interact with our country’s entry procedures. As part of this transformation, the Nigerian Visa Policy 2024 underwent a comprehensive review, resulting in a significant reduction in visa classifications from 79 to 44.
“These categories have been logically grouped to simplify procedures, reduce complexities, and greatly improve the user experience. Importantly, we have maintained the original purpose and intent of each visa class throughout this reform.”

Firm Discovers Sophisticated Chrome Zero-day Exploit Used in Active Attacks

Kaspersky has identified and helped patch a sophisticated zero-day vulnerability in Google Chrome (CVE-2025-2783) that allowed attackers to bypass the browser’s sandbox protection system.
The exploit, discovered by Kaspersky’s Global Research and Analysis Team (GReAT), required no user interaction beyond clicking a malicious link and demonstrated exceptional technical complexity. Kaspersky researchers have been acknowledged by Google for discovering and reporting this vulnerability.
In mid-March 2025, Kaspersky detected a wave of infections triggered when users clicked personalised phishing links delivered via email. After clicking, no additional action was needed to compromise their systems.
Once Kaspersky’s analysis confirmed that the exploit leveraged a previously unknown vulnerability in the latest version of Google Chrome, Kaspersky swiftly alerted Google’s security team. A security patch for the vulnerability was released on March 25, 2025.
Kaspersky researchers dubbed the campaign “Operation ForumTroll”, as attackers sent personalised phishing emails inviting recipients to the “Primakov Readings” forum. These lures targeted media outlets, educational institutions, and government organisations in Russia.
The malicious links were extremely short-lived to evade detection, and in most cases ultimately redirected to the legitimate website for “Primakov Readings” once the exploit was taken down.
The zero-day vulnerability in Chrome was only part of a chain that included at least two exploits: a still-unobtained remote code execution (RCE) exploit that apparently launched the attack, while the sandbox escape discovered by Kaspersky constituted the second stage. Analysis of the malware’s functionality suggests the operation was designed primarily for espionage. All evidence points to an Advanced Persistent Threat (APT) group.
“This vulnerability stands out among the dozens of zero-days we’ve discovered over the years,” said Boris Larin, principal security researcher at Kaspersky GReAT. “The exploit bypassed Chrome’s sandbox protection without performing any obviously malicious operations – it’s as if the security boundary simply didn’t exist.
The technical sophistication displayed here indicates development by highly skilled actors with substantial resources. We strongly advise all users to update their Google Chrome and any Chromium-based browser to the latest version to protect against this vulnerability.”
Google has credited Kaspersky for uncovering and reporting the issue, reflecting the company’s ongoing commitment to collaboration with the global cybersecurity community and ensuring user safety.
Kaspersky continues to investigate Operation ForumTroll. Further details, including a technical analysis of the exploits and malicious payload, will be released in a forthcoming report once Google Chrome user security is assured.
Meanwhile, all Kaspersky products detect and protect against this exploit chain and associated malware, ensuring users are shielded from the threat.
This discovery follows Kaspersky GReAT’s previous identification of another Chrome zero-day (CVE-2024-4947), which was exploited last year by the Lazarus APT group in a cryptocurrency theft campaign.
In that case, Kaspersky researchers found a type confusion bug in Google’s V8 JavaScript engine that enabled attackers to bypass security features through a fake cryptogame website.
