We recently found and analyzed a malicious malware variant that disguised itself as a legitimate Mac-based trading app called Stockfolio. We found two variants of the malware family. The first one contains a pair of shell scripts and connects to a remote site to decrypt its encrypted codes while the second sample, despite using a simpler routine involving a single shell script, is actually incorporates a persistence mechanism.Read More
By Carl Maverick Pascual (Threats Analyst) Cybercriminals continue to use cryptocurrency-mining malware to abuse computing resources for profit. As early as 2017, we have also observed how they have applied fileless techniques to make detection and monitoring more difficult. On August 2, we observed a fileless cryptocurrency-mining malware, dubbed GhostMiner, that weaponizes Windows management instrumentation…Read More
We discovered a series of incidents where the credit card skimming attack Magecart was used to hit the booking websites of chain-brand hotels — the second time we’ve seen a Magecart threat actor directly hit ecommerce service providers instead of going for individual stores or third-party supply chains.Read More
We looked into the security implications of the changing banking paradigm with PSD2 in place. Our research highlights the current and new risks that the financial industry will have to defend against, and predict how cybercriminals will abuse and attack Open Banking.Read More
Skidmap, a Linux malware that we recently stumbled upon, demonstrates the increasing complexity of recent cryptocurrency-mining threats. This malware is notable because of the way it loads malicious kernel modules to keep its cryptocurrency mining operations under the radar.
These kernel-mode rootkits are not only more difficult to detect compared to its user-mode counterparts — attackers can also use them to gain unfettered access to the affected system. A case in point: the way Skidmap can also set up a secret master password that gives it access to any user account in the system. Conversely, given that many of Skidmap’s routines require root access, the attack vector that Skidmap uses — whether through exploits, misconfigurations, or exposure to the internet — are most likely the same ones that provide the attacker root or administrative access to the system.Read More
