The FBI’s Internet Crime Complaint Center (IC3) has published its annual report for 2023, which reveals that the number of cybercrime complaints received by the agency increased by nearly 10% compared to the previous year.
Cybercrime victims in the United States filed more than 880,000 complaints with the FBI in 2023, with reported losses totaling over $12.5 billion, which represents a 22% increase from 2022. …
ESET researchers discovered a cyberespionage campaign that, since at least September 2023, has been victimizing Tibetans through a targeted watering hole (also known as a strategic web compromise), and a supply-chain compromise to deliver trojanized installers of Tibetan language translation software. The attackers aimed to deploy malicious downloaders for Windows and macOS to compromise website visitors with MgBot and a backdoor that, to the best of our knowledge, has not been publicly documented yet; we have named it Nightdoor.…

A cryptojacking campaign involving Linux malware is targeting misconfigured Apache Hadoop, Confluence, Docker, and Redis instances with new and unique malicious payloads, cybersecurity firm Cado Security warns.
As part of the campaign, the attackers employ four new Golang payloads to automate the discovery and exploitation of vulnerable hosts, as well as a reverse shell and multiple user-mode rootkits to hide their presence.…
Updated March 8: Based on our experience, we believe that BlackCat’s claim of shutting down due to law enforcement pressure is a hoax. We anticipate their return under a new guise or brand after their hiatus. This scam tactic serves as a means for them to execute one final significant scam before resurfacing with less scrutiny.…
Hackers are targeting misconfigured servers running Apache Hadoop YARN, Docker, Confluence, or Redis with new Golang-based malware that automates the discovery and compromise of the hosts.
The malicious tools used in the campaign take advantage of the configuration weaknesses and exploit an old vulnerability in Atlassian Confluence to execute code on the machine.…
Cado Security Labs researchers have recently encountered an emerging malware campaign targeting misconfigured servers running the following web-facing services:
The campaign utilises a number of unique and unreported payloads, including four Golang binaries, that serve as tools to automate the discovery and infection of hosts running the above services.…
North Korean hackers are using a critical vulnerability in ConnectWise’s ScreenConnect software to spread new, shapeshifting espionage malware.
Two weeks ago, ConnectWise revealed two flaws in its popular remote desktop application: CVE-2024-1708, a path traversal bug given a “high” score of 8.4 out of 10 on the CVSS scale, and CVE-2024-1709, a rare “critical” 10 out of 10 authentication bypass bug.…
The proliferation of programmable logic controllers (PLCs) with embedded Web servers in them has given attackers a way to launch potentially catastrophic, remote attacks against operational technology (OT) for industrial control systems (ICS) in critical infrastructure sectors.
To highlight the threat, a team of researchers from the Georgia Institute of Technology has developed malware that an adversary could use to remotely access an embedded Web server within a PLC, and attack the underlying physical system.…
