2023-07-19 19:06

Microsoft and the Ukraine CERT warn of new attacks by the Russian state-sponsored Turla hacking group, targeting the defense industry and Microsoft Exchange servers with a new 'DeliveryCheck' malware backdoor. The cyberspies have been associated with a wide array of attacks against Western interests over the years, including the Snake cyber-espionage malware botnet that was recently disrupted in an international law enforcement operation titled Operation MEDUSA. In a coordinated report and Twitter thread published today by CERT-UA and Microsoft, researchers outline a new attack where the Turla threat actors target the defense sector in Ukraine and Eastern Europe.

New proxyjacking attacks monetize hacked SSH servers’ bandwidth
2023-06-30 18:47

Attackers behind an ongoing series of proxyjacking attacks are hacking into vulnerable SSH servers exposed online to monetize them through proxyware services that pay for sharing unused Internet bandwidth. Like cryptojacking, which allows attackers to use hacked systems to mine for cryptocurrency, proxyjacking is a low-effort and high-reward tactic of leeching compromised devices' resources.

Cybercriminals Hijacking Vulnerable SSH Servers in New Proxyjacking Campaign
