Kaspersky Lab researchers warned that a spear phishing campaign has targeted roughly 500 organizations in the smelting, power generation and transmission, construction, and engineering industries across 50 countries since August 2016 in order to spy on users and steal sensitive data. The phishing emails contain a subject line with text used in a company’s correspondence in order to trick the victim into opening the malicious Rich Text Format (RTF) file attached, which downloads a malware that can diminish the ability of antivirus products.

December 19, SecurityWeek – (International) Privilege escalation, RCE flaws patched in Nagios Core. A security researcher from Legal Hackers discovered the Nagios Core alerting and monitoring software is plagued by two vulnerabilities, one of which is a remote code execution (RCE) flaw that can be exploited by a man-in-the-middle (MitM) attacker via the Rich Site Summary (RSS) feed feature, allowing the malicious actor to read and write arbitrary files on the compromised server, as well as execute code in the context of a Nagios user. Once an attacker achieves this level of access, the actor can exploit the second flaw to elevate their privileges to root, potentially causing the entire system to be compromised. Source

December 19, SecurityWeek – (International) MacBooks leak disk encryption password. A security researcher discovered that an attacker with physical access to a locked or sleeping Apple MacBook can retrieve the FileVault 2 password in clear text by connecting a special device to the targeted device’s Thunderbolt port due to the fact that the direct memory access (DMA) attack protections are not active before the operating system (OS) has booted, thereby enabling an attacker to read and write memory from a MacBook device via the Thunderbolt device. The researcher found that the attack does not work if the targeted MacBook has been turned off as the password is no longer available in the memory. Source
