Background for this topic.
A computer virus is malware that replicates by inserting its code into other programs or files. When an infected file runs, the virus may modify additional files on the same system and, in some cases, reach other systems through shared storage, removable media, or network access. The term is often used broadly in news, but technically it describes self-replicating, host-dependent malware rather than malware in general.
Viruses matter because infection can alter legitimate software, corrupt data, or provide a foothold for further malicious activity. Security teams should treat unexpected file changes, repeated detections, and unexplained program behavior as indicators for investigation. Useful controls include regularly patched systems, endpoint protection that detects suspicious file modification and execution, restricted use of removable media, and application controls that limit unapproved code. During an incident, isolate affected hosts, preserve samples and relevant logs, identify the original execution path, and restore only from verified clean sources.

Cybersecurity researchers have disclosed details of a new dual-vector campaign that leverages stolen credentials to deploy legitimate Remote Monitoring and Management (RMM) software for persistent remote access to compromised hosts
A combination of propagation methods, narrative sophistication, and evasion techniques enabled the social engineering tactic known as ClickFix to take off the way it did over the past year, according to new findings from Guardio Labs
China's National Computer Virus Emergency Response Center (CVERC) has doubled down on claims that the threat actor known as the Volt Typhoon is a fabrication of the U.S. and its allies
Imagine this... You arrive at work to a chaotic scene. Systems are down, panic is in the air. The culprit? Not a rogue virus, but a compromised identity. The attacker is inside your walls, masquerading as a trusted user. This isn't a horror movie, it's the new reality of cybercrime. The question is, are you prepared? Traditional incident response plans are like old maps in a new world. They
Like antivirus software, vulnerability scans rely on a database of known weaknesses
Select Ukrainian government networks have remained infected with a malware called OfflRouter since 2015
Every year hundreds of millions of malware attacks occur worldwide, and every year businesses deal with the impact of viruses, worms, keyloggers, and ransomware. Malware is a pernicious threat and the biggest driver for businesses to look for cybersecurity solutions. Naturally, businesses want to find products that will stop malware in its tracks, and so they search for solutions to do that.
Today, the LockBit ransomware is the most active and successful cybercrime organization in the world. Attributed to a Russian Threat Actor, LockBit has stepped out from the shadows of the Conti ransomware group, who were disbanded in early 2022
At least 1,200 Redis database servers worldwide have been corralled into a botnet using an "elusive and severe threat" dubbed HeadCrab since early September 2021
In this day and age, we are not dealing with roughly pieced together, homebrew type of viruses anymore. Malware is an industry, and professional developers are found to exchange, be it by stealing one's code or deliberate collaboration. Attacks are multi-layer these days, with diverse sophisticated software apps taking over different jobs along the attack-chain from initial compromise to
