Nobody Knows Where the Red Line Is for Cyberwarfare

Is offense the best defense? Or would threats of retaliation keep an enemy in check?

By: Katrina Manson, Bloomberg

A common explanation for why the Soviet Union never used nuclear weapons during the Cold War was the expectation that any attack would likely prompt a devastating nuclear response. The fear of mutually assured destruction was enough to keep both the USSR and the U.S. from launching a nuclear attack, even as they spent decades building up huge stockpiles of weapons.

Cyberweapons are different. Cyberattacks by both governments and private hackers have exploded in recent years. Many of these are financially motivated, but others involve espionage or, in several high-profile cases, the sabotage of physical infrastructure. There’s broad agreement that at some point a cyberattack would be considered an act of war. Yet no one knows quite where the line is.

FBI, CISA warn US hospitals of targeted BlackCat ransomware attacks

By Sergiu Gatlan,  Bleeping Computer Today, the FBI, CISA, and the Department of Health and Human Services (HHS) warned U.S. healthcare organizations of targeted ALPHV/Blackcat ransomware attacks. "ALPHV Blackcat affiliates have been observed primarily targeting the healthcare sector," the joint advisory cautions. Today's warning follows an April 2022 FBI flash alert and another advisory issued in December 2023 detailing the BlackCat cybercrime gang's activity since it surfaced in November 2021 as a suspected rebrand of the DarkSide and BlackMatter ransomware groups. The FBI linked BlackCat to over 60 breaches during its first four months of activity (between November 2021 and March 2022) and said the gang has raked in at least $300 million in ransoms from over 1,000 victims until September 2023. "Since mid-December 2023, of the nearly 70 leaked victims, the healthcare sector has been the most commonly victimized," the three federal agencies warned in today...

By Bill Toulas,  Bleeping Computer Nissan North America (Nissan) suffered a data breach last year when a threat actor targeted the company's external VPN and shut down systems to receive a ransom. The car maker discovered the breach in early November 2023 and discovered recently that the incident exposed personal data belonging to more than 53,000 current and former employees. “As shared during the Nissan Town Hall meeting on December 5, 2023, Nissan learned on November 7, 2023, that it was the victim of a targeted cyberattack. Upon learning of the attack, Nissan promptly notified law enforcement and began taking immediate actions to investigate, contain, and successfully terminate the threat,” the company said in a notification to impacted individuals. Nissan disclosed that the threat actor targeted its external VPN and then shut down certain company systems before asking for a ransom. The company notes that none of its systems were encrypted during the attack. Working with extern...

Why Your VPN May Not Be As Secure As It Claims

Image
By Krebs On Security Virtual private networking (VPN) companies market their services as a way to prevent anyone from snooping on your Internet usage. But new research suggests this is a dangerous assumption when connecting to a VPN via an untrusted network, because attackers on the same network could force a target’s traffic off of the protection provided by their VPN without triggering any alerts to the user. When a device initially tries to connect to a network, it broadcasts a message to the entire local network stating that it is requesting an Internet address. Normally, the only system on the network that notices this request and replies is the router responsible for managing the network to which the user is trying to connect. The machine on a network responsible for fielding these requests is called a Dynamic Host Configuration Protocol (DHCP) server, which will issue time-based leases for IP addresses. The DHCP server also takes care of setting a specific local address — known ...
