Cisco has unveiled AI-powered assistants for security defenses, aiming to simplify and bolster policies, alerts, and prevention. The AI Assistant for firewall policy helps reduce complexity in setting security policies and assess traffic without decryption. The AI-powered Encrypted Visibility Engine for all firewall models assesses if encrypted traffic contains malware without decryption. Cisco believes that the expanding number and sophistication of threats demands simplicity and protection at scale. The goal is to close the gap between intent and outcome by correlating native telemetry. #Cisco #AIPoweredAssistants #SecurityDefenses #CloudSecurity #Encryption
Summary: UEFI vulnerabilities known as LogoFAIL expose devices to stealthy malware attacks. These flaws allow hackers to gain unauthorized access, steal data, and compromise system integrity.

Summary:
The UK's financial regulator, the Financial Conduct Authority (FCA), has warned households in the country about the increase in loan fee fraud during Christmas. Many UK adults are concerned about affording Christmas expenses, leading them to turn to loans. Scammers take advantage of this and promise loans that victims never receive, tricking them into paying upfront charges. Last year, cases of loan fee fraud rose by 21% compared to the previous year, resulting in an average loss of £255. The FCA urges people to be vigilant and protect themselves from these scams.

Iran's Islamic Revolutionary Guard Corps (IRGC) is responsible for recent attacks on water plants, according to the US Cybersecurity and Infrastructure Security Agency (CISA). The IRGC's cyber group, "CyberAv3ngers," targeted Unitronics programmable logic controllers (PLCs), which are commonly used in various sectors including water systems, energy, and healthcare. The attacks were motivated by Unitronics being an Israeli manufacturer. The compromised devices had default passwords and were exposed to the internet, posing a risk to critical infrastructure. Providers are urged to change default passwords, disconnect PLCs from the internet, and implement cybersecurity measures. #Iran #Cybersecurity #WaterSectorAttacks #CriticalInfrastructure

Breaches by Iran-Affiliated Hackers Spanned Multiple U.S. States. Iran-linked hackers targeted a specific Israeli-made industrial control device. The FBI, EPA, CISA, and Israel's National Cyber Directorate issued an advisory. The hackers are affiliated with Iran's Islamic Revolutionary Guards Corps. The devices are used in various industries, including energy and healthcare. The hackers left a digital calling card on the compromised device. The access they gained could have led to more profound cyber physical effects. Cybersecurity experts warn of Iranian involvement in attacks on Israel. The Iran-affiliated hackers are known as "Cyber Av3ngers". The Unitronics devices are vulnerable due to poor password security and exposure to the internet. The water sector and critical infrastructure are under-resourced and highly critical. Three Pennsylvania congressmen have called for an investigation into the hack. The Biden administration is trying to improve cybersecurity of critical infrastructure.
Google recently developed and unveiled RETVec, a resilient and efficient text vectorizer to defend Gmail users against malicious emails and spam. RETVec is a next-gen text vectorizer with built-in adversarial resilience that is able to handle character-level manipulations like insertion, deletion, typos, homoglyphs, and LEET substitution. It supports 100+ languages without lookup tables or fixed vocabulary and can be easily employed in TensorFlow models for string vectorization. RETVec improves spam detection by 38% with a 0.80% false positive rate, reducing latency by 30%. It is competitive for real-world tasks and eliminates the need for a vocabulary layer in smaller language models. However, optimizing RETVec for multilingual skills, robustness, and smaller models in large language models poses challenges, as does its use in generative models. Future work will address these limitations and explore RETVec's potential as a word embedding tool. #cybersecurity #RETVec
