In a previous memo, I mentioned the discovery, made by researchers at Kaspersky, of an active campaign carried out by an advanced threat actor since 2021, targeting multiple organizations in the regions of Donetsk, Lugansk, and Crimea. One of the noteworthy aspects of this campaign was undoubtedly the usage of a new backdoor, called PowerMagic, characterized by the exploitation of the popular cloud storage services, Dropbox and OneDrive, as the command and control infrastructure.

Kroll’s findings for Q1 2023 highlight fragmented threat actor groups and a continued evolution in attack methods and approaches, which, alongside other key shifts in behavior, have concerning implications for organizations in many sectors. In Q1 2023, Kroll observed a 57% increase in the overall targeting of the professional services sector from the end of 2022.

Something as common and widely known as a software update can prevent major cyberattacks from happening, as they incorporate patches that fix system vulnerabilities. Prioritizing updates may seem a burdensome and inconvenient task for users, because computers and servers have to restart to perform installation, which interrupts users when they are working.

Since 2020, CrowdStrike has increasingly observed big game hunting (BGH) threat actors deploying Linux versions of ransomware tools specifically designed to affect VMWare’s ESXi vSphere hypervisor (read Part 1 and Part 2 of this series).

Attackers use a variety of tactics to spread laterally across on-premises Windows machines, including Pass-the-Ticket, Pass-the-Hash, Overpass-the-Hash and Golden Tickets attacks. But similar techniques are also effective in moving laterally from a compromised workstation to connected cloud resources, bypassing strong authentication measures like MFA. This article explains how attackers can perform lateral movement to the cloud with an attack called Pass-the-PRT.

Web applications are vulnerable to several kinds of attacks, but they’re particularly susceptible to code injection attacks. One such attack, the XPath Injection, takes advantage of websites that require user-supplied information to access data stored in XML format. All sites that use a database in XML format might be vulnerable to this attack. XPath is a query syntax that websites can use to search their XML data stores.

Typosquatting goes by many names: URL hijacking, domain mimicry and domain typo-squatting, to name a few. However, they all mean the same thing: malicious attackers register domain names similar to popular websites but with common typos and variations. Typosquatting aims to trick users who mistype the legitimate URL into visiting and using the fraudulent site. It is a widespread practice.

A lot of us are fascinated with technology. Any form or mention of the subject piques an interest or at least a glance of curiosity. Unfortunately, we must endure the dark side of technology as well. From the beginning of the computer age, there have always been hackers who could match their criminal expertise to current technologies. Some hackers are concerned with small scams and easy entry points.

Five worthy reads is a regular column on five noteworthy items we’ve discovered while researching trending and timeless topics. This week, we are exploring mobile malware attacks, how they have exploited users, and the ways to prevent them in the digital era.
