February 3, 2020 By Tom Spring Popular trojan is sneaking its way onto PCs via malspam campaign that uses three levels of encryption to sneak past cyber defenses. A recent wave of AZORult-laced spam caught the attention of researchers who warn that malicious attachments associated with the campaign are using a novel obfuscation technique, in an attempt to slip past spam gateways and avoid client-side antivirus detection. What makes this campaign unique is the use by threat actors of a triple-encrypted AZORult downloader being pushed by the otherwise non-descript malspam assault. AZORult is remote access trojan popular on Russian forums and most recently spotted last month in a spam campaign perpetrated by a hacker with an affinity toward singer-songwriter Drake.

February 5, 2020 By Tom Spring Malware campaign targets global manufacturers that are still dependent on Windows 7 subsystems to run fleets of IoT endpoints. Printers, smart TVs and automated guided vehicles that depend on Windows 7 have become the latest juicy targets for cybercriminals leveraging a “self-spreading” variant of the malware Lemon Duck. In a report released Wednesday by TrapX Security, researchers warn manufacturers dependent on IoT devices are targets in a new global campaign leveraging the malware variant. Criminals behind the wave of attacks are singling out IoT gear in hopes of enlisting them into a “slave army” of crypto-mining devices focused on generating Monero coins via the XMRig mining tool. Researchers warn that the processor-intensive mining efforts are taking their toll on gear and triggering equipment malfunctions along with exposing devices to safety issues, disruption of supply chains and data loss.

February 6, 2020 By Lawrence Abrams Google is moving forward with its plan to block mixed content downloads from web sites to protect users from man-in-the-middle attacks. In April 2019, we reported that Google was looking into blocking mixed content downloads, which are files delivered over insecure HTTP connection when they are first initiated from HTTPS websites. In an announcement posted today, Google has outlined their plan of gradually rolling out this feature in Chrome by first displaying console warnings to the eventual blocking of all mixed content downloaded files. Google states that they are blocking these types of downloads as they are a risk to a user's security and privacy as they could be swapped out or viewed in man-in-the-middle (MiTM) attacks.

January 22, 2020 By Jérôme Segura In the early days, practically all tech support scammers would get their own leads by doing some amateur SEO poisoning and keyword stuffing on YouTube and other social media sites. They’d then leverage their boiler room to answer incoming calls from victims. Today, these practices continue, but we are seeing more advanced operations with a clear separation between lead generation and actual call fulfillment. Malvertising campaigns and redirections from compromised sites to browser locker pages are owned and operated by experienced purveyors of web traffic. There is one particular browser locker (browlock) campaign that had been eluding us for some time. It stands apart from the others, striking repeatedly on high-profile sites, such as the Microsoft Edge Start page, and yet, eluding capture. In addition, and a first to our knowledge, the browser locker pages were built to be ephemeral with unique, time-sensitive session tokens. In November 2019, we
These truly are the end times for TLS 1.0, 1.1: Firefox hopes to 'eradicate' weak HTTPS standard by blocking it
Mozilla's browser will, from March, require manual override By Tim Anderson 10 Feb 2020 Mozilla Firefox will require user intervention to connect to websites using the TLS 1.0 or 1.1 protocol from March 2020 – and plans to eventually block those weak HTTPS connections entirely. We have been hearing about issues with TLS 1.0 and 1.1 for some time. Web servers should really be using TLS 1.2 or 1.3 for their encrypted and secure HTTPS connections. The PCI Data Security Standard (PCI DSS) for sites handling credit card transactions has required at least TLS 1.1 since 1 July 2018. That said, it is not until March this year that most users will see more than a warning in their web browser, and some browsers do not show any warning. We took a look at a website running TLS 1.0 in a variety of web browsers today. Of these: Full Article.
MSP vendors Datto, Huntress Labs and ConnectWise helped save an MSP's access credentials from being sold on the dark web’s auction block. February 10, 2020 By O’Ryan Johnson A chilling post to an online black-market bulletin board that began “I’m selling access to an MSP…” was spotted by channel security researchers who were then able to catfish the suspect, warn the MSP and work with the FBI, which later arrested him. “We decided amongst the Datto and Huntress teams that we weren’t going to stand for hackers to come after MSPs,” Huntress CEO Kyle Hanslovan told CRN. “What started out as a simple Torum post -- where hackers sell vulnerabilities, they sell access, they sell stolen credit cards, you name it – we decided to take it a step further.” Over the course of a few months the hacker known as “w0zniak” had used his jobs as a systems engineer at an MSP and at a tax preparation service to steal account information for businesses and individuals – from the inside -- and then post
