???? Important Security Update from Google! ????

Google has just released a crucial security update for its Chrome browser, fixing seven vulnerabilities, including a high-severity zero-day bug (CVE-2023-6345) in the Skia graphics library. Discovered by Benoît Sevens and Clément Lecigne of Google's Threat Analysis Group, this exploit is actively being used in the wild. ????

The update addresses a total of seven zero-days in Chrome this year, covering issues like type confusion, integer overflow, and heap buffer overflow. Users are strongly advised to upgrade to Chrome version 119.0.6045.199/.200 (for Windows) and 119.0.6045.199 (for macOS and Linux) ASAP to stay protected.

Chromium-based browser users (Microsoft Edge, Brave, Opera, Vivaldi) should also apply fixes when available. Stay safe online! ????????

Now, on to today’s hottest cybersecurity stories:

  • ???? CACTUS ransomware exploits flaws in Qlik Sense ????

  • ???? Korea criminals Lazurus hit $3 billion in crypto hacks ????

  • ???? Introducing Google’s new RETVec, tackling phishing ????

???? Ransomware Alert: CACTUS Exploits Qlik Sense Flaws! ????

 The campaign leverages three disclosed flaws in Qlik Sense over the past three months, including a high-severity HTTP Request Tunneling vulnerability (CVE-2023-41265), a path traversal bug (CVE-2023-41266), and an unauthenticated remote code execution issue (CVE-2023-48365). Notably, CVE-2023-48365 stems from an incomplete patch for CVE-2023-41265.

???? Attack Tactics

In these attacks, cybercriminals exploit Qlik Sense Scheduler to establish persistence, deploying tools like ManageEngine UEMS and AnyDesk. The attackers go further by uninstalling Sophos software, changing admin passwords, and creating RDP tunnels.

????️ Culmination in Ransomware

The attacks culminate in the deployment of CACTUS ransomware, with rclone used for data exfiltration.

???? Evolving Ransomware Landscape

This revelation aligns with the evolving ransomware landscape, showcasing increased sophistication and collaboration among threat actors. Despite global efforts, ransomware-as-a-service (RaaS) remains lucrative.

???? Black Basta's Illicit Gains

The notorious Black Basta group, linked to Conti and QakBot, has reportedly garnered over $107 million in Bitcoin ransom payments. These proceeds were laundered through a Russian cryptocurrency exchange, Garantex.

???? North Korean Hackers Target Cryptocurrency for Revenue Generation! ????

Cybersecurity firm Recorded Future reveals an alarming trend as threat actors from the Democratic People's Republic of Korea (DPRK) increasingly focus on the cryptocurrency sector for revenue since 2017, sidestepping imposed sanctions. ????????

???? Despite heavy restrictions on movement, DPRK's ruling elite and skilled computer science professionals leverage privileged access to conduct cyber attacks on the cryptocurrency industry. The U.S. Treasury Department recently sanctioned Sinbad, a virtual currency mixer used by the North Korea-linked Lazarus Group to launder proceeds.

???? Estimated to have stolen $3 billion in crypto assets over six years, with $1.7 billion in 2022 alone, these funds directly finance the nation's weapons programs. Notably, $1.1 billion was stolen through DeFi protocol hacks, making North Korea a significant force in the DeFi hacking trend.

???? The U.S. DHS warns of Lazarus Group exploiting DeFi protocols, emphasising the challenges in attributing stolen cryptocurrency transitions. DPRK hackers excel at social engineering, targeting cryptocurrency exchange employees, conducting phishing tactics, airdrop scams, rug pulls, and utilising mixing services to conceal financial trails.

???? Without stronger regulations and cybersecurity measures, North Korea is likely to persist in targeting the cryptocurrency industry for additional revenue, warns Recorded Future. Stay vigilant and ensure robust cybersecurity for the evolving threat landscape! ????????????

???? Google Unveils RETVec: Boosting Gmail's Defense Against Harmful Content! ????

Google introduces RETVec (Resilient and Efficient Text Vectorizer), a multilingual text vectorizer designed to enhance the detection of spam and malicious emails in Gmail. ????

????️ Resilient Defense Against Manipulations

RETVec is uniquely trained to withstand character-level manipulations, including insertion, deletion, typos, homoglyphs, LEET substitution, and more. The model utilises a novel character encoder that efficiently encodes all UTF-8 characters and words.

???? Multilingual and Robust

Working across 100+ languages, RETVec aims to fortify server-side and on-device text classifiers, offering resilience against adversarial text manipulations employed by threat actors to bypass traditional defences.

???? Vectorization in NLP

Vectorization, a method in natural language processing (NLP), maps words or phrases to numerical representations for analysis. RETVec's novel architecture supports all languages and UTF-8 characters without preprocessing, making it ideal for various applications.

???? Performance Boost in Gmail

Integrated into Gmail, RETVec significantly improved spam detection by 38%, reduced false positives by 19.4%, and lowered Tensor Processing Unit (TPU) usage by 83%. Its compact representation enhances inference speed, reducing computational costs and latency.

???? Ideal for On-Device and Large-Scale Deployments

Due to its efficiency, RETVec proves ideal for on-device, web, and large-scale text classification deployments, aligning with Google's commitment to enhancing cybersecurity defences. Stay protected from evolving threats with the latest advancements! ????????????????
