∗∗∗ Cloudflare blocks largest recorded DDoS attack peaking at 3.8Tbps ∗∗∗
---------------------------------------------
During a distributed denial-of-service campaign targeting organizations in the financial services, internet, and telecommunications sectors, volumetric attacks peaked at 3.8 terabits per second, the largest publicly recorded to date. The assault consisted of a "month-long" barrage of more than 100 hyper-volumetric DDoS attacks flood. [..] Many of the attacks aimed at the target’s network infrastructure (network and transport layers L3/4) exceeded two billion packets per second (pps) and three terabits per second (Tbps). [..] The threat actor behind the campaign leveraged multiple types of compromised devices, which included a large number of Asus home routers, Mikrotik systems, DVRs, and web servers.

∗∗∗ Over 4,000 Adobe Commerce, Magento shops hacked in CosmicSting attacks ∗∗∗
---------------------------------------------
Approximately 5% of all Adobe Commerce and Magento online stores, or 4,275 in absolute numbers, have been hacked in "CosmicSting" attacks. [..] The CosmicSting vulnerability (CVE-2024-34102) is a critical severity information disclosure flaw; when chained with CVE-2024-2961, a security issue in glibc's iconv function, an attacker can achieve remote code execution on the target server. [..] Sansec says that multiple threat actors are now conducting attacks as patching speed is not matching the critical nature of the situation.

∗∗∗ Survey of CUPS exploit attempts, (Fri, Oct 4th) ∗∗∗
---------------------------------------------
It is about a week since the release of the four CUPS remote code execution vulnerabilities. After the vulnerabilities became known, I configured one of our honeypots that watches a larger set of IPs to specifically collect UDP packets to port 631. Here is a quick summary of the results.

∗∗∗ Apple fixes bug that let VoiceOver shout your passwords ∗∗∗
---------------------------------------------
Apple just fixed a duo of security bugs in iOS 18.0.1 and iPadOS 18.0.1, one of which might cause users' saved passwords to be read aloud. It's hardly an ideal situation for the visually impaired. For those who rely on the accessibility features baked into their iGadgets, namely Apple's VoiceOver screen reader, now is a good time to apply the latest update.

∗∗∗ DRAY:BREAK Breaking Into DreyTek Routers Before Threat Actors Do It Again ∗∗∗
---------------------------------------------
In 2024, routers are a primary target for cybercriminals and state-sponsored attackers – and are the riskiest device category on networks. With this knowledge, we investigated one vendor with a history of security flaws to help it address its issues and prevent new attacks. Our latest research discovered 14 new vulnerabilities in DrayTek routers.

∗∗∗ Threat actor believed to be spreading new MedusaLocker variant since 2022 ∗∗∗
---------------------------------------------
Talos has recently observed an attack leading to the deployment of a MedusaLocker ransomware variant known as “BabyLockerKZ.” The distinguishable techniques — including consistently storing the same set of tools in the same location on compromised systems, the use of tools that have the PDB path with the string “paid_memes,” and the use of a lateral movement tool named “checker” — used in the attack led us to take a deeper look to try to understand more about this threat actor.
