SLAM Attack: New Spectre-based Vulnerability Impacts Intel, AMD, and Arm CPUs

SLAM Attack: New Spectre-based Vulnerability Impacts Intel, AMD, and Arm CPUs

Dec 09, 2023 Cyber Threat / Hardware Security
Researchers from the Vrije Universiteit Amsterdam have disclosed a new side-channel attack called  SLAM  that could be exploited to leak sensitive information from kernel memory on current and upcoming CPUs from Intel, AMD, and Arm. The attack is an end-to-end exploit for Spectre based on a new feature in Intel CPUs called  Linear Address Masking  ( LAM ) as well as its analogous counterparts from AMD (called  Upper Address Ignore  or  UAI ) and Arm (called  Top Byte Ignore  or  TBI ). "SLAM exploits unmasked gadgets to let a userland process leak arbitrary ASCII kernel data," VUSec researchers  said , adding it could be leveraged to leak the root password hash within minutes from kernel memory. While LAM is presented as a security feature, the study found that it ironically degrades security and "dramatically" increases the  Spectre attack surface , resulting in a transient execution attack, which exploits  speculative execution  to extract sensitive data via

Arm Issues Patch for Mali GPU Kernel Driver Vulnerability Amidst Ongoing Exploitation

Oct 03, 2023 Cyber Attack / Vulnerability
Arm has released security patches to contain a security flaw in the Mali GPU Kernel Driver that has come under active exploitation in the wild. Tracked as  CVE-2023-4211 , the shortcoming impacts the following driver versions - Midgard GPU Kernel Driver: All versions from r12p0 - r32p0 Bifrost GPU Kernel Driver: All versions from r0p0 - r42p0 Valhall GPU Kernel Driver: All versions from r19p0 - r42p0 Arm 5th Gen GPU Architecture Kernel Driver: All versions from r41p0 - r42p0 "A local non-privileged user can make improper GPU memory processing operations to gain access to already freed memory," Arm  said  in a Monday advisory. "There is evidence that this vulnerability may be under limited, targeted exploitation." The issue, credited to Maddie Stone of Google's Threat Analysis Group (TAG) and Jann Horn of Google Project Zero, has been addressed in Bifrost, Valhall and Arm 5th Gen GPU Architecture Kernel Driver r43p0.

Cybersecurity Tactics FinServ Institutions Can Bank On in 2024

Feb 14, 2024Financial Security / Cyber Threats
The landscape of cybersecurity in financial services is undergoing a rapid transformation. Cybercriminals are exploiting advanced technologies and methodologies, making traditional security measures obsolete. The challenges are compounded for community banks that must safeguard sensitive financial data against the same level of sophisticated threats as larger institutions, but often with more limited resources. The FinServ Threat Landscape Recent trends show an alarming increase in sophisticated cyber-attacks. Cybercriminals now deploy advanced techniques like deep fake technology and AI-powered attacks, making it increasingly difficult for banks to differentiate between legitimate and malicious activities. These developments necessitate a shift towards more sophisticated and adaptive cybersecurity measures. Take these industry statistics, for example. Financial firms report 703 cyberattack attempts per week.1 On average, 270 attacks (entailing unauthorized access of data, appl

Japan's Softbank buys semiconductor giant ARM for $32 Billion in Cash

Jul 18, 2016
Japanese telecommunication giant SoftBank has confirmed that the company intends to acquire UK chip designer ARM Holdings for almost $32 Billion (£24.3 Billion) in an all-cash deal. ARM has also agreed to this offer from SoftBank and said that its board would recommend the all-cash deal to shareholders. SoftBank will pay nearly $22.5 per ARM share, which is 43 percent more than ARM's closing share price on Friday and 41 percent more than ARM's all-time high closing share price. The deal is the largest-ever acquisition of a European technology business, first reported by The Financial Times. Wondering Why is ARM really Worth $32 Billion? Founded in 1990, Cambridge-based ARM Holdings designs microchips for a variety of smartphones and powers more than 95 percent of the smartphones in the market. Whether it is Apple's iPhones or iPads, Samsung's Galaxy smartphones, Amazon's Kindle e-readers, the cheapest Nokia phones or Internet-connected devices li
