Apple released emergency security updates to patch three new zero-day vulnerabilities exploited in attacks targeting iPhone and Mac users, for a total of 16 zero-days patched this year.
Google researchers say currently unfixed vulnerability affects a popular software package.
UNC4841 has continued operations despite Barracuda ESG zero-day remediation efforts.
Vulnerability allows hackers to execute malicious code when targets open malicious ZIP files.
App Management is a new macOS security feature in Ventura introduced at WWDC last year:
If an app is modified by something that isn't signed by the same development team and isn't allowed by an NSUpdateSecurityPolicy, macOS will block the modification and notify the user that an app wants to manage other apps. Clicking on the notification sends people to System Settings, where they can allow an app to update and modify other apps.
US-based IT software company Ivanti warned customers today that a critical Sentry API authentication bypass vulnerability is being exploited in the wild.
On May 31, threat actors were discovered targeting a critical zero day in MOVEit Transfer software resulting in escalated privileges and unauthorized data access. The vulnerability being exploited is an SQL injection and has since been patched. Resources links, including one for the patch, are at the bottom of this post.
Analysis of a zero-day vulnerability in MOVEit Transfer, and containment and hardening guidance.
A vulnerability (CVE-2023-2868) in Barracuda Networks' ESG appliances is actively exploited by attackers, the company has warned.
Google has released an emergency Chrome security update to address the first zero-day vulnerability exploited in attacks since the start of the year.
Fast-growing e-commerce app Pinduoduo had an EvilParcel stow-away.
In late 2022 and early 2023, Project Zero reported eighteen 0-day vulnerabilities in Exynos Modems produced by Samsung Semiconductor. The four most severe of these eighteen vulnerabilities (CVE-2023-24033 and three other vulnerabilities that have yet to be assigned CVE-IDs) allowed for Internet-to-baseband remote code execution. Tests conducted by Project Zero confirm that those four vulnerabilities allow an attacker to remotely compromise a phone at the baseband level with no user interaction, and require only that the attacker know the victim's phone number. With limited additional research and development, we believe that skilled attackers would be able to quickly create an operational exploit to compromise affected devices silently and remotely.
Huntress is tracking CVE-2023-23397, a 0-day that impacts Microsoft Outlook and requires no user interaction to expose user credential hashes.
Microsoft’s March 2023 Patch Tuesday Addresses 76 CVEs (CVE-2023-23397)Microsoft addresses 76 CVEs including two zero-days exploited in the wild, one of which was publicly disclosed.
An employee of cyberweapon manufacturer, NSO Group, tried to sell advanced malware to unauthorized parties for $50-Million, according to an Israeli indictment unsealed last week against the individual in question. About two years ago, Herzliya-based NSO Group developed a powerful cyberweapon called Pegasus, which operated as malware that exploited three previously unknown vulnerabilities in iPhones […]
GoAnywhere MFT, a popular file transfer application, is warning about a zero-day remote code injection exploit. The company said it has temporarily implemented a service outage in response.
A Russian zero-day exploit purchase site is interested in tools for hacking of Electric Vehicle Charging Stations. This raises a number of questions. Why would anybody want to hack such targets? Also, why would Russian entities (in particular) be interested in such targets? The best answer to these is “good question!”, and let's put politics aside. Let’s explore the potential cybersecurity risks of electric vehicle charging station, assuming the ability of compromising them at a scale, having some kind of tools. It turns out that this is a fascinating security problem!
By now you have likely already heard about the in-the-wild exploitation of Exchange Server, chaining CVE-2022-41040 and CVE-2022-41082. It was originally submitted to the ZDI program by the researcher known as “DA-0x43-Dx4-DA-Hx2-Tx2-TP-S-Q from GTSC”. After successful validation, it was immediately
Earlier this year, Mandiant identified a novel malware ecosystem impacting VMware ESXi, Linux vCenter servers, and Windows virtual machines that enables a threat actor to take the following actions:
1) Maintain persistent administrative access to the hypervisor
2) Send commands to the hypervisor that will be routed to the guest VM for execution
3) Transfer files between the ESXi hypervisor and guest machines running beneath it
4) Tamper with logging services on the hypervisor
Circa the beginning of August 2022, while doing security monitoring & incident response services, GTSC SOC team discovered that a critical infrastructure was being attacked, specifically to their Microsoft Exchange application. During the investigation, GTSC Blue Team experts determined that the attack utilized an unpublished Exchange security vulnerability, i.e., a 0-day vulnerability, thus immediately came up with a temporary containment plan.
