IT services and business consulting company HTC Global Services has recently confirmed that they suffered a cyberattack after the ALPHV ransomware gang began leaking screenshots of stolen data.  HTC Global Services is a managed service provider offering technology and business services to the healthcare, automotive, manufacturing, and financial industries.  According to the ALPHV ransomware group, the leaked data includes passports, contact lists, emails, and confidential documents.

According to Cornell University researchers, attackers could manipulate responses to user prompts from Large Language Models (LLMs) behind Artificial Intelligence (AI) chatbots like ChatGPT by hiding malicious instructions in strategically placed images and audio clips online. Adversaries could use "indirect prompt injection" attacks to redirect users to malicious URLs, collect personal information from users, deliver payloads, and perform other malicious actions.

A vulnerability in an open-source library used widely in the Web3 space compromises the security of pre-built smart contracts, impacting many NFT collections, including Coinbase. Thirdweb, a Web3 development platform, said it became aware of the security flaw on November 20 and pushed a fix two days later. However, the company did not reveal the name of the library or the type or severity of the vulnerability to avoid tipping off attackers.

Japanese car maker Nissan is investigating a recent cyberattack that targeted its systems in Australia and New Zealand, which may have let hackers access personal information.  Nissan Oceania is a regional division of the famous Japanese automaker that covers distribution, marketing, sales, and services in Australia and New Zealand.

According to security researchers at ZeroFox, the LockBit ransomware strain continues to be the primary digital extortion threat to all regions and almost all industries globally.  The researchers found that LockBit was leveraged in more than a quarter of global ransomware and digital extortion (R&DE) attacks in the seven quarters analyzed from January 2022 to September 2023.  This includes 30% of all R&DE attacks in Europe and 25% in North America during the period.

According to security researchers at Forescout, some Sierra Wireless cellular routers are affected by 21 vulnerabilities, including ones that could pose a significant risk to impacted organizations, including in critical infrastructure sectors.  The vulnerabilities, collectively tracked as "Sierra:21", were found in Sierra Wireless AirLink OT/IoT routers that are often used to connect local networks to the web in sectors such as healthcare, manufacturing, government, energy, water, transportation, emergency services, and retail.

The US cybersecurity agency CISA recently added four bugs impacting multiple Qualcomm chipsets to its Known Exploited Vulnerabilities (KEV) Catalog.  All four issues were identified by Google’s Threat Analysis Group and Google Project Zero, which often report security defects exploited by commercial spyware vendors.  CISA noted that three of the flaws tracked as CVE-2023-33106, CVE-2023-33107, and CVE-2023-33063 were patched in October 2023 as zero days after Qualcomm learned from Google’s researchers that they were likely exploited in the wild.

North Carolina State University researchers discovered that Artificial Intelligence (AI) tools are more vulnerable than previously thought to attacks aimed at forcing AI systems to make bad decisions. According to the researchers, the issue is what are known as "adversarial attacks," in which someone manipulates the data fed into an AI system in order to confuse it. For example, a hacker could install code on an X-ray machine to modify image data in order to cause an AI system to make incorrect diagnoses.

In recent years, there has been more access to cost-effective and efficient means and services for executing Denial-of-Service (DoS) attacks. Ongoing global conflicts have sparked many DoS attacks. The "ENISA Threat Landscape for DoS Attacks" report delves into the motivations and consequences of DoS attacks, with the goal of helping organizations strengthen their defenses against such attacks. The findings come from a thorough mapping and analysis of DoS incidents from January 2022 to August 2023.

According to the Cybersecurity and Infrastructure Security Agency (CISA), hackers compromised public-facing servers at a US federal agency in June and July by exploiting a vulnerability in a popular Adobe product. The hackers exploited a bug impacting Adobe ColdFusion versions 2018 Update 15 (and earlier) and 2021 Update 5 (and earlier), as well as earlier installations of the software no longer supported by Adobe. CISA says there is no evidence of data exfiltration or lateral movement by the hackers.
