High-Severity Firmware Security Flaws Left Unpatched in HP Enterprise Devices

High-Severity Firmware Security Flaws Left Unpatched in HP Enterprise Devices

Sep 12, 2022
A number of firmware security flaws uncovered in HP's business-oriented high-end notebooks continue to be left unpatched in some devices even months after public disclosure. Binarly, which first  revealed details  of the issues at the  Black Hat USA conference  in mid-August 2022, said the vulnerabilities "can't be detected by firmware integrity monitoring systems due to limitations of the Trusted Platform Module (TPM) measurement." Firmware flaws can have serious implications as they can be abused by an adversary to achieve long-term persistence on a device in a manner that can survive reboots and evade traditional operating system-level security protections. The high-severity weaknesses identified by Binarly affect HP EliteBook devices and concern a case of memory corruption in the System Management Mode (SMM) of the firmware, thereby enabling the execution of arbitrary code with the highest privileges - CVE-2022-23930  (CVSS score: 8.2) - Stack-based buffer
New 16 High-Severity UEFI Firmware Flaws Discovered in Millions of HP Devices

New 16 High-Severity UEFI Firmware Flaws Discovered in Millions of HP Devices

Mar 08, 2022
Cybersecurity researchers on Tuesday disclosed 16 new high-severity vulnerabilities in various implementations of Unified Extensible Firmware Interface (UEFI) firmware impacting multiple HP enterprise devices. The  shortcomings , which have CVSS scores ranging from 7.5 to 8.8, have been uncovered in HP's UEFI firmware. The variety of devices affected includes HP's laptops, desktops, point-of-sale (PoS) systems, and edge computing nodes. "By exploiting the vulnerabilities disclosed, attackers can leverage them to perform privileged code execution in firmware, below the operating system, and potentially deliver persistent malicious code that survives operating system re-installations and allows the bypass of endpoint security solutions (EDR/AV), Secure Boot and Virtualization-Based Security isolation," American firmware security company Binarly said in a report shared with The Hacker News. The most severe of the flaws concern a number of memory corruption vulnera
Midnight Blizzard and Cloudflare-Atlassian Cybersecurity Incidents: What to Know

Midnight Blizzard and Cloudflare-Atlassian Cybersecurity Incidents: What to Know

Feb 13, 2024SaaS Security / Data Breach
The Midnight Blizzard and Cloudflare-Atlassian cybersecurity incidents raised alarms about the vulnerabilities inherent in major SaaS platforms. These incidents illustrate the stakes involved in SaaS breaches — safeguarding the integrity of SaaS apps and their sensitive data is critical but is not easy. Common threat vectors such as sophisticated spear-phishing, misconfigurations and vulnerabilities in third-party app integrations demonstrate the complex security challenges facing IT systems. In the case of Midnight Blizzard, password spraying against a test environment was the initial attack vector. For Cloudflare-Atlassian, threat actors initiated the attack via compromised  OAuth tokens  from a prior breach at Okta, a SaaS identity security provider.  What Exactly Happened? Microsoft Midnight Blizzard Breach Microsoft was targeted by the Russian "Midnight Blizzard" hackers (also known as Nobelium, APT29, or Cozy Bear) who are linked to the SVR, the Kremlin's forei
Pre-Installed Keylogger Found On Over 460 HP Laptop Models

Pre-Installed Keylogger Found On Over 460 HP Laptop Models

Dec 09, 2017
HP has an awful history of 'accidentally' leaving keyloggers onto its customers' laptops. At least two times this year, HP laptops were caught with pre-installed keylogger or spyware applications. I was following a tweet made by a security researcher claiming to have found a built-in keylogger in several HP laptops, and now he went public with his findings. A security researcher who goes by the name of ZwClose discovered a keylogger in several Hewlett-Packard (HP) laptops that could allow hackers to record your every keystroke and steal sensitive data, including passwords, account information, and credit card details. The Keylogger was found embedded in the SynTP.sys file, a part of Synaptics touchpad driver that ships with HP notebook computers, leaving more than 460 HP Notebook models vulnerable to hackers. Although the keylogger component is disabled by default, hackers can make use of available open source tools for bypassing User Account Control (UAC) to

Beware! Built-in Keylogger Discovered In Several HP Laptop Models

Beware! Built-in Keylogger Discovered In Several HP Laptop Models

May 11, 2017
Do you own a Hewlett-Packard (HP) laptop? Yes? Just stop whatever you are doing and listen carefully: Your HP laptop may be silently recording everything you are typing on your keyboard. While examining Windows Active Domain infrastructures, security researchers from the Switzerland-based security firm Modzero have discovered a built-in keylogger in an HP audio driver that spy on your all keystrokes. In general, Keylogger is a program that records every keystroke by monitoring every key you have pressed on your keyboard. Usually, malware and trojans use this ability to steal your account information, credit card numbers, passwords, and other private data. HP computers come with Audio Chips developed by Conexant, a manufacturer of integrated circuits, who also develops drivers for its audio chips. Dubbed Conexant High-Definition (HD) Audio Driver, the driver helps the software to communicate with the hardware. Depending upon the computer model, HP also embeds some code i
