The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a critical Microsoft COM for Windows vulnerability, tracked as CVE-2018-0824, to its Known Exploited Vulnerabilities (KEV) catalog. This deserialization of untrusted data flaw, with a CVSS score of 7.5, can enable remote code execution through improperly handled serialized objects. Recently exploited by the China-linked APT41 group against a Taiwanese research institute, the vulnerability was used to deploy ShadowPad malware and other tools.
Mozilla has released Firefox 129.0, bringing significant security enhancements to the popular browser. This update addresses 14 unique security vulnerabilities, including several with a high aggregate severity rating. Although there are no reports of these vulnerabilities being exploited in the wild, the fixes are crucial for maintaining user safety. The update also includes improvements in handling HTTPS, now prioritizing secure connections by default for non-local addresses, and enhancing DNS security by using system DNS settings on supported operating systems.
Researchers have uncovered a new campaign involving the Chameleon Android banking trojan, which disguises itself as a Customer Relationship Management (CRM) app to target users. The campaign, identified in July 2024 by Dutch security firm ThreatFabric, primarily affects users in Canada and Europe, expanding from earlier targets in Australia, Italy, Poland, and the U.K. Once installed, the trojan pretends to be a legitimate CRM tool, tricking users into logging in and then displaying false error messages to deploy the malware.
A critical vulnerability in Kibana, identified as CVE-2024-37287 with a CVSSv3 severity rating of 9.9, has been revealed to allow attackers to execute arbitrary code. This flaw, stemming from prototype pollution, affects multiple Kibana environments, including self-managed installations, Docker images, and Elastic Cloud instances. The vulnerability impacts Kibana versions below 8.14.2 in the 8.x series and below 7.17.23 in the 7.x series.
A recent study by Elastic Security reveals that reputation-based security measures like Windows Smart App Control (SAC) and SmartScreen are increasingly vulnerable to sophisticated attack techniques. Attackers are bypassing these protections by employing methods such as digitally signing malware with extended validation SSL certificates, manipulating code signing, and using tactics like "LNK Stomping" to evade detection.
The Port of Tyne's website in North East England was disrupted on Tuesday due to a distributed denial of service (DDoS) attack, which aimed to overload the site and render it inaccessible. Despite the website issues, the port confirmed that its operational systems, which are maintained separately, were not impacted and that all data remains secure. The port swiftly restored full website functionality and is currently collaborating with relevant parties to investigate the source of the attack.
McLaren Health Care, based in Grand Blanc, MI, is investigating a significant disruption to its phone and computer systems that may be linked to a ransomware attack. The outage has led to operational challenges, including the redirection of ambulances to other facilities due to lost access to electronic medical records. While some non-emergent procedures may be rescheduled, patients are advised to attend their appointments as scheduled unless contacted by hospital staff.

The Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) have unveiled the "Secure by Demand Guide," designed to help organizations ensure software security during procurement. Released on August 6, 2024, the guide provides practical advice for assessing software manufacturers' cybersecurity practices, including key questions to ask and considerations for integrating security into the procurement lifecycle.
The UK's Information Commissioner’s Office (ICO) has announced a provisional ￡6.1 million fine for Advanced Computer Software Group following a serious ransomware attack in August 2022. The breach exposed the personal information of nearly 83,000 individuals, including sensitive medical records and details on how to gain physical access to the homes of 890 care recipients. The attack severely disrupted NHS services, affecting patient referrals, appointment bookings, and emergency prescriptions.
Samsung has unveiled a significant new initiative aimed at bolstering the security of its mobile devices. The company’s 'Important Scenario Vulnerability Program' (ISVP) offers up to $1,000,000 in rewards for critical vulnerabilities that enable arbitrary code execution, device unlocking, or data extraction. The program targets weaknesses in Samsung’s Knox Vault, Trusted Execution Environment (TEEGRIS OS), and Rich OS, with varying rewards based on the severity of the vulnerability.
Darktrace's latest report reveals alarming trends in email security, analyzing 17.8 million phishing emails and finding that 62% passed domain-based message authentication, reporting, and conformance (DMARC) checks. Over a third of these emails avoided detection by major email providers, and 56% evaded all existing security measures, highlighting significant gaps in current defenses.
