A Russian state-sponsored cyber espionage group known as Static Tundra has been observed actively exploiting a seven-year-old security flaw in Cisco IOS and Cisco IOS XE software as a means to establish persistent access to target networks. Cisco Talos, which disclosed details of the activity, said the attacks single out organizations in telecommunications, higher education and manufacturing sectors across North America, Asia, Africa and Europe. Prospective victims are chosen based on their "strategic interest" to Russia, it added, with recent efforts directed against Ukraine and its allies following the onset of the Russo-Ukrainian war in 2022. The vulnerability in question is CVE-2018-0171 (CVSS score: 9.8), a critical flaw in the Smart Install feature of Cisco IOS Software and Cisco IOS XE software that could allow an unauthenticated, remote attacker to trigger a denial-of-service (DoS) condition or execute arbitrary code. It's worth noting that the security ...

Tor has always been a tough target for law enforcement for years and FBI has spent millions of dollars to de-anonymize the identity of Tor users, but a latest research suggests that more than 81% of Tor clients can be "de-anonymised" by exploiting the traffic analysis software 'Netflow' technology that Cisco has built into its router protocols. NetFlow is a network protocol designed to collect and monitor network traffic. It exchanged data in network flows, which can correspond to TCP connections or other IP packets sharing common characteristics, such UDP packets sharing source and destination IP addresses, port numbers, and other information. The research was conducted for six years by professor Sambuddho Chakravarty , a former researcher at Columbia University's Network Security Lab and now researching Network Anonymity and Privacy at the Indraprastha Institute of Information Technology in Delhi. Chakravarty used a technique, in order to determine the Tor...

Threat hunters have discovered a network of more than 1,000 compromised small office and home office (SOHO) devices that have been used to facilitate a prolonged cyber espionage infrastructure campaign for China-nexus hacking groups. The Operational Relay Box (ORB) network has been codenamed LapDogs by SecurityScorecard's STRIKE team. "The LapDogs network has a high concentration of victims across the United States and Southeast Asia, and is slowly but steadily growing in size," the cybersecurity company said in a technical report published this week. Other regions where the infections are prevalent include Japan, South Korea, Hong Kong, and Taiwan, with victims spanning IT, networking, real estate, and media sectors. Active infections span devices and services from Ruckus Wireless, ASUS, Buffalo Technology, Cisco-Linksys, Cross DVR, D-Link, Microsoft, Panasonic, and Synology.  LapDogs' beating heart is a custom backdoor called ShortLeash that's engineered...
