Pre-Installed Keylogger Found On Over 460 HP Laptop Models (December 8, 2017)
A security researcher going by the name “ZwClose” has released information regarding a pre-installed keylogger located in the “Synaptics” touchpad driver. The Synaptics driver is shipped with HP machines, and approximately 460 HP models were observed to contain this keylogging feature. Researchers note that the keylogger feature is disabled by default, however, threat actors could use open source tools for bypassing the User Account Control to enabled the keylogger “by setting a registry value.”

A Peculiar Case of Orcus RAT Targeting Bitcoin Investors (December 7, 2017)
As the value of the “Bitcoin” cryptocurrency continues to increase (approximately $17,740 USD as of this writing) threat actors are subsequently increasing their efforts to target Bitcoin investors. Fortinet researchers have found that actors are targeting Bitcoin investors with a Remote Access Trojan (RAT) called “Orcus” via a phishing campaign. The phishing emails purport to be an announcement of a new, legitimate bitcoin trading bot called “Gunbot.” The email attachment contains a VB script that, when executed, will download a file impersonating a .jpeg. The .jpeg file is actually a portable executable binary file. The executable was found to be a trojanized version of an open source inventory tool called “TTJ-Inventory System.” Inside this malicious versions, researcher discovered the presence of the “Orcus” RAT, which is advertised as a Remote Access Tool created by Orcus Technologies. Orcus has numerous features and commands that it can run, however, researcher note that what separates Orcus is the ability to load custom plugins.

New Targeted Attack in the Middle East by APT34, A Suspected Iranian Threat Group, Using CVE-2017-11882 (December 7, 2017)
FireEye researchers have published a report regarding a new Advanced Persistent Threat (APT) group they have dubbed “APT34.” The group is believed to be based in Iran, and has been observed exploiting a Microsoft Office vulnerability (CVE-2017-11882) that Microsoft patched on November 14, 2017. The vulnerability was exploited while attacking an unnamed government organization in the Middle East. Researchers believe that the APT group has been conducting a long-term cyber espionage campaign to benefit Iranian national interests. The group is believed to have been active since at least 2014. The group was observed using spear phishing emails that attempt to drop public and custom malicious tools, such as the group’s custom PowerShell backdoor to achieve its goals.

Master Channel: The Boleto Mestra Campaign Targets Brazil (December 7, 2017)
Palo Alto Unit 42 researchers have discovered a new malspam campaign, dubbed “The Boleto Mestre Campaign” because the links and attachments in the emails masquerade as “Boleto Bancário.” Boleto Bancário is an official payment method that is regulated by the Central Bank of Brazil. Researchers have observed over 260,000 emails that fall under this theme since June 2017. The objective of this campaign is trick a user into following a malicious link or open a document that will infect the recipient with an information stealing trojan.

Mailsploit: It’s 2017, and You Can Spoof The “From” in Email to Fool Filters (December 6, 2017)
Penetration tester, Sabri Haddouche, has discovered that more than 30 email clients are vulnerable to email source spoofing. The vulnerability has been dubbed “Mailsploit.” The email clients are vulnerable to spoofing because of improper implementation of the Request For Comments (RFC) 1342 (which dates back to 1992) that can allow source spoofing to bypass spam filters and security features such as Domain-based Message Authentication, Reporting and Conformance (DMARC). RFC 1342 has to do with the representation of non-ASCII character in Internet message headers. Haddouche identified that the mail client interfaces do not properly sanitize a non-ASCII string after it is decoded.

StorageCrypt Ransomware Infecting NAS Devices Using SambaCry (December 5, 2017)
A new ransomware, dubbed “StorageCrypt,” is targeting Network-Attached Storage (NAS) devices, according to Bleeping Computer researchers. The threat actors behind this campaign are using the Linux Samba vulnerability “SambaCry,” Samba is a Windows suite of programs for Linux and Unix. Exploitation of the vulnerability allows an actor to open a command shell on the affected machine that can be used to download file and execute commands. The actors are demanding a ransom from anywhere between 0.4 (approximately $6,356 USD) to 2 (approximately $31,779 USD) bitcoins for the decryption key.

Dridex is Back, Baby! – Necurs Botnet Malspam Pushes Dridex (December 4, 2017)
Researchers have discovered that “Necurs” botnet has resumed its distribution of the “Dridex” banking malware. Researchers note that the last occurrence of Necurs Dridex distribution was identified in June 2017, and that this Necurs campaign is separate from the “Globeimposter” ransomware campaign. The emails purport to be discussing a credit card payment and provides a link to receive the confirmation of the payment. If the link if followed, it will retrieve a malicious Word document. Inside the document is an embedded object that generates up to four URLs to retrieve the Dridex installer.

Apache Software Foundation Releases Security Updates (December 4, 2017)
An alert has been released by the United States Computer Emergency Readiness Team (US-CERT) concerning vulnerabilities in Apache products. Specifically, the vulnerabilities are located in Apache Struts versions 2.5 through 2.5.14. The US-CERT states that an actor could exploit one of these vulnerabilities to take control of an affected system. One of the vulnerabilities can be exploited by an actor via a custom JSON request that can be used to conduct a Denial-of-Service (DoS) when using an outdated json-lib with Struts REST plugin. The second vulnerability is located in the Jackson JSON library, however, the impact of the issue is, as of this writing, still being researched further.

Necurs Botnet Malspam Pushed Globeimposter Ransomware (December 4, 2017)
Researchers have observed that the “Necurs” botnet, known for distributing “Locky” ransomware, is currently distributing the “Globeimposter” ransomware. The ransomware is being distributed via malspam that contain malicious attachments. The emails purport that a message is ready to be sent with the following file or link attachments, or that an attached file is a confirmation of a credit card payment per the recipient’s request. Opening the attachment will begin the infection process for Globeimposter. The threat actors behind this campaign are demanding 0.088 Bitcoin (approximately $1,037 USD) for the decryption key.

Seamless Campaign Serves RIG EK via Punycode (December 4, 2017)
Malwarebytes Labs researchers have published information regarding the history and current activity regarding the “Seamless” malvertising campaign. The Seamless campaigns are known for almost exclusively distributing the “Ramnit” banking trojan via the RIG exploit kit. Threat actors are currently running two Seamless campaigns simultaneously; one that use static strings and IP literal URLs (URLs that skip DNS), and another that uses special characters. In the latter campaign, actors are using a Cryllic-based domain name that is then transcribed via “Punycode” (encoding used to convert Unicode characters to ASCII). According to researchers, the malvertisements are typically distributed via adult portals that redirect to malicious domains to begin the infection process for Ramnit.
