The developers behind the TrickBot have once again upgraded the information stealer’s evasion capabilities. This time, the new trojan variant checks for screen resolution before proceeding with its infection process. If the computer screen resolution does not meet the trojan’s requirement, then it terminates.

The XMRig cryptocurrency miner and Alina PoS malware have also returned in the last 24 hours with their new versions. While the new variant of XMRig camouflages as system Windows Management Instrumentation (WMI) service, the latest version of Alina malware uses DNS tunneling to evade detection from antivirus.

Top Breaches Reported in the Last 24 Hours

A hacker has uploaded ransom notes on 22,900 MongoDB databases that were left exposed online without passwords. The hacker is using an automated script to scan for unsecured MongoDB databases, wiping their content, and leaving a ransom note behind asking for a ransom of 0.015 bitcoin. The hacker is giving companies two days’ time to pay, after which they threaten to leak data and contact the victim’s local General Data Protection Regulation (GDPR) enforcement authority to report the data leak.
