∗∗∗ JasperLoader Emerges, Targets Italy with Gootkit Banking Trojan ∗∗∗
---------------------------------------------
Malware loaders are playing an increasingly important role in malware distribution. They give adversaries the ability to gain an initial foothold on a system and are typically used to deliver various malware payloads following successful compromise. These attacks are popping up more frequently, as we covered in July with Smoke Loader and Brushaloader earlier this year.

∗∗∗ Erpressungs-E-Mail von mir selbst ∗∗∗
---------------------------------------------
Momentan versenden Kriminelle E-Mails, in denen Sie behaupten Ihre Webcam gehackt und Sie beobachtet zu haben. Sie hätten angeblich Videomaterial, das Sie beim Masturbieren zeigt. Ihnen droht eine Veröffentlichung des Films, wenn Sie nicht einen bestimmten Geldbetrag in Form von Bitcoins überweisen. Weiters scheint es so, als hätten die Kriminellen die E-Mail von Ihrem Account aus an Sie selbst versendet. Bleiben Sie ruhig, es handelt sich um einen Betrugsversuch!

∗∗∗ Unpatched Vulnerability Alert - WebLogic Zero Day, (Thu, Apr 25th) ∗∗∗
---------------------------------------------
The news today is full of a new deserialization vulnerability in Oracle WebLogic. This affects all current versions of the product (the POC is against 10.3, but 12.x versions are also affected). The vulnerability affects the wls9_async_response package (which is not included by default in all builds), so the workaround is to either ACL the Z/_async/* and /wls-wsat/* paths, or delete wls9_async_response.war. A successful attack gets the attacker remote code exec on the vulnerable server.

∗∗∗ Technical Advisory: Private Key Extraction from Qualcomm Hardware-backed Keystores ∗∗∗
---------------------------------------------
Recent Android devices include a hardware-backed keystore, which developers can use to protect their cryptographic keys with secure hardware. On some devices, Qualcomms TrustZone-based keystore leaks sensitive information through the branch predictor and memory caches, enabling recovery of 224 and 256-bit ECDSA keys.
