North Korea Exploited VPN Flaw to Hack South's Nuclear Research Institute

North Korea Exploited VPN Flaw to Hack South's Nuclear Research Institute

June 18, 2021Ravie Lakshmanan
South Korea's state-run Korea Atomic Energy Research Institute (KAERI) on Friday disclosed that its internal network was infiltrated by suspected attackers operating out of its northern counterpart. The intrusion is said to have taken place on May 14 through a vulnerability in an unnamed virtual private network (VPN) vendor and involved a  total of 13 IP addresses , one of which — "27.102.114[.]89" — has been previously linked to a state-sponsored threat actor dubbed  Kimsuky . KAERI, established in 1959 and situated in the city of Daejeon, is a government-funded research institute that designs and develops nuclear technologies related to reactors, fuel rods, radiation fusion, and nuclear safety. Following the intrusion, the think tank said it took steps to block the attacker's IP addresses in question and applied necessary security patches to the vulnerable VPN solution. "Currently, the Atomic Energy Research Institute is investigating the subject of the ha

A new report published by cybersecurity researchers has unveiled evidence of Iranian state-sponsored hackers targeting dozens of companies and organizations in Israel and around the world over the past three years. Dubbed " Fox Kitten ," the cyber-espionage campaign is said to have been directed at companies from the IT, telecommunication, oil and gas, aviation, government, and security sectors. "We estimate the campaign revealed in this report to be among Iran's most continuous and comprehensive campaigns revealed until now," ClearSky researchers said . "The revealed campaign was used as a reconnaissance infrastructure; however, it can also be used as a platform for spreading and activating destructive malware such as ZeroCleare and Dustman." Tying the activities to threat groups APT33, APT34, and APT39, the offensive — conducted using a mix of open source and self-developed tools — also facilitated the groups to steal sensitive information

New Linux Bug Lets Attackers Hijack Encrypted VPN Connections

A team of cybersecurity researchers has disclosed a new severe vulnerability affecting most Linux and Unix-like operating systems, including FreeBSD, OpenBSD, macOS, iOS, and Android, that could allow remote 'network adjacent attackers' to spy on and tamper with encrypted VPN connections. The vulnerability, tracked as CVE-2019-14899, resides in the networking stack of various operating systems and can be exploited against both IPv4 and IPv6 TCP streams. Since the vulnerability does not rely on the VPN technology used, the attack works against widely implemented virtual private network protocols like OpenVPN, WireGuard, IKEv2/IPSec, and more, the researchers confirmed. This vulnerability can be exploited by a network attacker — controlling an access point or connected to the victim's network — just by sending unsolicited network packets to a targeted device and observing replies, even if they are encrypted. As explained by the researchers, though there are variati
