CISA Alerts Federal Agencies to Patch Actively Exploited Linux Kernel Flaw

Posted by in category: cybercrime/malcode

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a security flaw impacting the Linux kernel to the Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation.

Tracked as CVE-2024–1086 (CVSS score: 7.8), the high-severity issue relates to a use-after-free bug in the netfilter component that permits a local attacker to elevate privileges from a regular user to root and possibly execute arbitrary code.

“Linux kernel contains a use-after-free vulnerability in the netfilter: nf_tables component that allows an attacker to achieve local privilege escalation,” CISA said.

Hackers Created Rogue VMs to Evade Detection in Recent MITRE Cyber Attack

Posted by in category: cybercrime/malcode

The MITRE Corporation has revealed that the cyber attack targeting the not-for-profit company towards late December 2023 by exploiting zero-day flaws in Ivanti Connect Secure (ICS) involved the actor creating rogue virtual machines (VMs) within its VMware environment.

“The adversary created their own rogue VMs within the VMware environment, leveraging compromised vCenter Server access,” MITRE researchers Lex Crumpton and Charles Clancy said.

“They wrote and deployed a JSP web shell (BEEFLUSH) under the vCenter Server’s Tomcat server to execute a Python-based tunneling tool, facilitating SSH connections between adversary-created VMs and the ESXi hypervisor infrastructure.”

Beware: These Fake Antivirus Sites Spreading Android and Windows Malware

Posted by in categories: cybercrime/malcode, robotics/AI

It’s currently not clear how these bogus websites are distributed, but similar campaigns in the past have employed techniques such as malvertising and search engine optimization (SEO) poisoning.

Stealer malware have increasingly become a common threat, with cybercriminals advertising numerous custom variants with varying levels of complexity. This includes new stealers like Acrid, SamsStealer, ScarletStealer, and Waltuhium Grabber, as well as updates to existing ones such as SYS01stealer (aka Album Stealer or S1deload Stealer).

Hackers are now targeting the children of corporate executives in elaborate ransomware attacks

Posted by in category: cybercrime/malcode

In February, ransomware attackers targeted Chain Healthcare, the payment management arm of healthcare giant UnitedHealth Group, causing backlogs in prescription insurance claims.

Ransomware can be introduced to a company’s databases through even the smallest slip by an employee, like clicking a link in a phishing email. But as companies have gotten better at keeping criminals out, the crooks have gotten more creative, Mandiant CTO Charles Carmakal says.

Are You Ready for Tech That Connects to Your Brain?

Posted by in categories: business, cybercrime/malcode, education, neuroscience

Imagine having telepathic conversations with loved ones, instantaneously accessing superhuman computational power, playing back memories and dreams, or immersing yourself and every sense you possess into a virtual entertainment experience. In the distant future, if brain-computer interfaces (BCIs) are successful at reading and writing information to the brain, and if humans adapt to the technology, we could experience some pretty amazing scenarios. But, there are many outstanding questions for how we could ensure a bright future: Who will own the data generated by our brains? Will brain data be bought and sold by data brokers like other personal information today? Will people be forced to use certain BCIs that surveil their brain activity (for example, to make sure you’re paying attention at work and school)? Will BCIs put peoples’ brains at risk of being hacked? As with all new technology, more of these philosophical questions will need to be investigated and answered before there is widespread adoption and use of BCIs in the future.
