The unknown threat actor managed to somehow access an employee's email account and then sent the organisation fake invoices for solar panels for a Pakistani health centre, along with other documents.

This vulnerability has been called "Magellan" and allows for threat actors to remotely execute arbitrary and/or malicious code on machines, leak program memory, or even crash applications. Researchers were able to develop a successful Proof-of-Concept (PoC) exploit with the vulnerability, though they will not release the technical details or PoC publicly until patches for all applications are released. This vulnerability affects a large variety of users and applications such as Adobe, Apple, Android, Chrome, Dropbox, FireFox, Internet-of-Things (IoT) devices, Microsoft, and many others that utilise SQLite for their disk-based relational database management.

The campaign targets institutions in the defence, energy, financial, and telecommunications sectors narrowing on English-speaking organisations in Australia, Europe, India, Japan, the Middle East, South America, and the US. The observed phishing emails were themed around recruitment, containing a seemingly legitimate job description and Word document attachment from a man named "Richard." The document requests macros to be enabled, and if allowed, an embedded shellcode injects a downloader for a backdoor called "Rising Sun." This allows for the threat actor to gain reconnaissance capabilities on the machine and obtain information such as documents, network configurations, system settings, and usernames that then sends the information to the designated Command and Control (C2) server.

In October 2018, the APT group was reported to have been observed attacking US financial institution infrastructure, potentially as a reaction to the sanctions placed against Iran. In November 2018, the domain "accounts[-]support[.]services," believed to be associated to Charming Kitten, was found to be used to target human and civil rights activists, political figures as well as Iranian and Western journalists in phishing attacks. The APT group initiates contact via email or social media, or via compromised accounts of known public figures, and notifies their targets with fake alerts of unauthorised users attempting to access their accounts. This alert then prompts the user to enter their username and password credentials to "secure" their account on a fake Google login page, which then gives the APT group access to those credentials.<br/> <a href="https://forum.anomali.com/t/the-return-of-the-charming-kitten/3343" target="_blank">Click here for </a><a href="https://forum.anomali.com/t/the-return-of-the-charming-kitten/3343" target="_blank">Anomali</a><a href="https://forum.anomali.com/t/the-return-of-the-charming-kitten/3343" target="_blank"> recommendation </a><br/> <b>MITRE ATT&amp;CK: </b> <a href="https://ui.threatstream.com/ttp/947106">[MITRE ATT&amp;CK] Spearphishing Link (T1192)</a> | <a href="https://ui.threatstream.com/ttp/947269">[MITRE ATT&amp;CK] Access Token Manipulation (T1134)</a></p><p><a href="https://www.bleepingcomputer.com/news/security/new-bomb-threat-email-scam-campaign-demanding-20k-in-bitcoin/" target="_blank"><b>New Bomb Threat Email Scam Campaign Demanding $20K in Bitcoin </b></a> (<i>December 13, 2018</i>)<br/> A new phishing email extortion campaign has been observed targeting a variety of people in the US.

CVE-2015-1427 is a vulnerability in Elasticsearch's "Groovy" scripting engine that can allow for remote arbitrary commands to be executed. CVE-2014-3120 is a vulnerability in Elasticsearch's default configuration that can allow for remote execution of arbitrary MVEL expressions and Java code. The attacks attempt to install cryptominers onto the infected machine through running a command that attempts to distribute a bash script to evoke the shell to run and download the mining malware. The threat actor will then run arbitrary commands to obtain privilege escalation and attempt to pivot to other systems connected to the network. The actual mining file is called "devtools" in the script in an attempt to obfuscate it on the machine, and once installed, it will search for other miners in the system and kill those to prevent them from restarting so it has sole control. It runs every ten minutes to mine for as much cryptocurrency as possible from the system.

The trojan is distributed via malware found in a fake battery optimisation application found in third-party stores and exploits the Android Accessibility services. The fake battery-optimiser tool offers zero functionality and hides its icon whilst it attempts to gain accessibility service functions on the device. It will request the "enabling of statistics" and then alert the user to launch the official PayPal application if it is already loaded onto the device. Once the user logs into the application, the malicious accessibility service will intervene and mimic the user's clicks to send the threat actor money (1000 euros though currency depends on the user's location) to their PayPal account. The malware also uses phishing displays over legitimate applications such as Gmail, Google Play, Skype, Viber, and WhatsApp, with a credit card details page.

According to the research paper produced by the researchers who identified this vulnerability, the SplitSpectre vulnerability "splits the Spectre v1 gadget into two parts: one consisting of the conditional branch and the array access (phase 3), and the other one consisting of the second array access that constitutes the sending part of the side channel (phase 4). This has the advantage that the second part, phase 4, can now be placed into the attacker-controlled code. It is more likely that an attacker finds such gadgets, thereby alleviating one of the main difficulties of performing a v1 attack.
