November 17, Help Net Security – (International) Ransoc browser locker/ransomware blackmails victims. Security researchers discovered the Ransoc ransomware is being distributed via malvertising to target and blackmail Microsoft Windows users who frequent adult Websites, and scans an infected device to collect information from the victim’s Facebook, LinkedIn, and Skype accounts, as well as scans local media filenames for strings associated with files downloaded via torrents in order to uncover illegal or illicit content. The ransomware then displays a ransom note, or “penalty notice” tailored to the information it finds, threatening to expose a victim’s illicit online activity to the user’s social and professional network connections if the fine is not paid.

November 21, Help Net Security – (International) Malware masquerading as an image spreads via Facebook. A malware researcher discovered malware is spreading via Facebook in the form of Scalable Vector Graphics (SVG) image files that contain embedded content and are automatically sent from compromised user accounts in order to redirect users to a Website impersonating YouTube where a victim is required to install a specific codec extension before viewing the video, which gives the malware the capability to alter a user’s data on the Websites they visit. The researcher reported the SVG file also contains the Nemucod downloader; however it has not been spotted downloading the Locky ransomware or other malware. Source

November 22, Softpedia – (International) US Government invites hackers to attack US Army domains. The U.S. Department of Defense (DOD) and partner company HackerOne reported November 22 that hackers can now register for the Hack the Army bug bounty challenge, which will allow 500 security researchers to hack U.S. Army domains and find unpatched vulnerabilities in exchange for a reward. DOD officials reported the program concerns any public-facing Website that is owned, operated, or controlled by the department, and is part of an effort to explore new security approaches. Source

November 21, SecurityWeek – (International) Code execution flaws patched in HDF5 library. The HDF Group released version 1.8.18 of its HDF5 library after researchers from Cisco’s Talos Vulnerability Development Team discovered the library was plagued with a total of 4 local heap-buffer overflow flaws that could allow an attacker to execute arbitrary code in the context of the application using the library if they trick a victim into opening a maliciously crafted file. The vulnerabilities are the result of a failure to check if the number of dimensions for an array from a file is within bounds, failure to check if certain message types support a specific flag, and insufficient handling of select values in memory when parsing a Hierarchical Date Format (HDF) file, among other failures. Source

November 22, SecurityWeek – (International) Office 365 flaw made fake Microsoft emails look legitimate. A Turkey-based security researcher discovered a flaw in Microsoft Office 365 that could be exploited by attackers to send malicious emails and make them appear as if they were sent from a legitimate email address after a test of different email services’ spam filters found that some of his phishing emails that were marked as valid came from a spoofed address and were forwarded through Outlook 365 to the Yandex email service. Additional testing found that Gmail also accepted the spoofed emails that were forwarded from Outlook as legitimate. Source

November 22, SecurityWeek – (International) Siemens releases firmware updates to patch SIMATIC flaws. Siemens released firmware updates for its SIMATIC S7-300 and S7-400 controllers, and its SIMATIC CP 343-1 and CP 443-1 Advanced communications processors resolving several medium-severity flaws after security researchers discovered the affected devices contain an integrated Web server on port 80/TCP or 443/TCP that enables a malicious actor to carry out operations with privileges of an authenticated user. The researchers also discovered a flaw related to the Web server delivering cookies without the “secure” flag, among other patched flaws. Source
