Background for this topic.
Malware is software intentionally created or modified to perform unauthorized or harmful actions on a computer, device, or network. The term covers distinct families and functions, including viruses, worms, trojans, spyware, botnet clients, and ransomware; a single sample may combine several capabilities. Its behavior—not its label—determines the security concern: it may execute code, persist, alter or encrypt data, steal credentials, or provide unauthorized remote access.
For practitioners, malware reporting is most useful when it identifies the family or tool conservatively and provides evidence such as affected platforms, samples, infrastructure, or observed behavior. Defenses include promptly patching vulnerable software, restricting execution and privileges, monitoring endpoints and networks, maintaining tested backups, and isolating suspected systems for analysis. Detection should use behavior and verified indicators rather than names alone, since variants change. If malware processes personal or regulated data, investigations should also address privacy, evidence preservation, and applicable reporting obligations.
Investigating the ESG bug, Rapid7 assumed the presence of persistent malware hindering device wipes
Bitdefender researchers warn that mods and plugins have been rigged by the infostealer malware, dubbed Fractureiser
A new custom backdoor dubbed Stealth Soldier has been deployed as part of a set of highly-targeted espionage attacks in North Africa
We look into BatCloak engine, its modular integration into modern malware, proliferation mechanisms, and interoperability implications as malicious actors take advantage of its fully undetectable (FUD) capabilities.
It's not often that a zero-day vulnerability causes a network security vendor to urge customers to physically remove and decommission an entire line of affected hardware -- as opposed to just applying software updates. But experts say that is exactly what transpired this week with Barracuda Networks, as the company struggled to combat a sprawling malware threat which appears to have undermined its email security appliances in such a fundamental way that they can no longer be safely updated with software fixes.
The malware focuses on surveillance operations, according to a new advisory by Check Point Research
If the chocolate factory's scans don't stop the miners, customers don't foot the bill Google Cloud has put $1 million on the table to cover customers' unauthorized compute expenses stemming from cryptomining attacks if its sensors don't spot these illicit miners.…

Attackers could exploit a common AI experience—false recommendations—to spread malicious code via developers that use ChatGPT to create software.
AI is beefing up the cyber arsenals of both attackers and defenders Sponsored Feature Email is a popular target for cybercriminals, offering an easy way of launching an attack disguised as an innocent message. One moment of inattention on the part of the recipient and the door is open to malware, spam, phishing, perhaps even a dose of the dreaded ransomware. Entire organisations can suffer, not just individual victims.…
