TrickBot Now Exploits Infected PCs to Launch RDP Brute Force Attacks
A new module for TrickBot banking Trojan has recently been discovered in the wild that lets attackers leverage compromised systems to launch brute-force attacks against selected Windows systems running a Remote Desktop Protocol (RDP) connection exposed to the Internet. The module, dubbed “rdpScanDll,” was discovered on January 30 and is said to be still in development, said cybersecurity firm Bitdefender in a report shared with The Hacker news. According to the researchers, the rdpScanDll brute-forcing module has so far attempted to target 6,013 RDP servers belonging to enterprises in telecom, education, and financial sectors in the U.S. and Hong Kong. The malware authors behind TrickBot specialize in releasing new modules and versions of the Trojan in an attempt to expand and refine its capabilities.

Most Ransomware Gets Executed Three Days After Initial Breach
Ransomware gets deployed three days after an organization’s network gets infiltrated in the vast majority of attacks, with post-compromise deployment taking as long as 299 days in some of the dozens of attacks researchers at cybersecurity firm FireEye examined between 2017 and 2019. In 75% of all ransomware incidents, as they found, the attackers will delay encrypting their victims’ systems and will use that time to steal Domain Admin credentials that they can later use to distribute the ransomware payloads throughout the compromised environment. More recently, ransomware operators have also started to harvest and exfiltrate their victims’ data, later using it as leverage to make them pay the ransoms under the threat of leaking the stolen information.

(Last) Week in Ransomware – March 13th 2020 – Stay Safe
This has been a slow week in terms of new variants, but we continue to see enterprise-targeting ransomware operators threatening to release data for non-paying victims. With Coronavirus on everyone’s minds, malware developers have turned to campaigns utilizing COVID-19 themed phishing scams or malware to take advantage of the panic and anxiety induced by the outbreak. Of particular interest, are two ransomware infections called CoronaVirus Ransomware and CovidLock that use the outbreak as a theme for their infections.

Nation-Backed Hackers Spread Crimson RAT via Coronavirus Phishing
A state-sponsored threat actor is attempting to deploy the Crimson Remote Administration Tool (RAT) onto the systems of targets via a spear-phishing campaign using Coronavirus-themed document baits disguised as health advisories. This nation-backed cyber-espionage is suspected to be Pakistan-based and it is currently tracked under multiple names including APT36, Transparent Tribe, ProjectM, Mythic Leopard, and TEMP.Lapis. The group, active since at least 2016, is known for targeting Indian defense and government entities and for stealing sensitive info designed to bolster Pakistan’s diplomatic and military efforts.

Trend Micro Patches Two Zero-Days Under Attack
Businesses are urged to update the Apex One and OfficeScan XG enterprise security products as soon as possible. Trend Micro has issued critical patches for several vulnerabilities in its Apex One and OfficeScan XG enterprise security products. Attackers have tried to exploit at least two of these flaws. CVE-2020-8467, one of the two zero-days, is a critical remote code execution vulnerability in a migration tool component in Apex One and OfficeScan. This could allow remote attackers to execute arbitrary code in affected installations. The second zero-day, CVE-2020-8468, is a content validation escape flaw that could let an attacker manipulate certain agent client components. Both of these require valid user credentials for exploitation, Trend Micro reports.

Working from Home: COVID-19’s Constellation of Security Challenges
Organizations are sending employees and students home to work and learn — but implementing the plan opens the door to more attacks, IT headaches and brand-new security challenges. As the threat of coronavirus continues to spread, businesses are sending employees home to work remotely, and students are moving to online classes. But with the social distancing comes a new threat – a cyber-related one. As organizations rush to shift their businesses and classes online, cybercriminals are ramping up their tactics to take advantage of those who may have inadequate or naive security postures as a result. Given the challenges in securing work- and learn-from-home environments, the attack surface represents an attractive opportunity for threat actors.
The Insecurity of WordPress and Apache Struts
A study that analyzed all the vulnerability disclosures between 2010 and 2019 found that around 55% of all the security bugs that have been weaponized and exploited in the wild were for two major application frameworks, namely WordPress and Apache Struts.
The Drupal content management system ranked third, followed by Ruby on Rails and Laravel, according to a report published this week by risk analysis firm RiskSense.
