A new wave of cyber-attacks linked to the Ghostwriter threat actor has been observed focusing on Ukraine and opposition groups in Belarus. The latest campaign, uncovered by SentinelLABS, employs weaponized Excel documents designed to deliver malicious payloads through phishing attacks. Ghostwriter’s New Tactics Ghostwriter, a cyber-espionage group linked to the Belarusian government, has evolved its attack strategies. SentinelLABS found that the group now uses Excel spreadsheets as phishing lures, embedding obfuscated VBA macros to execute…

In my previous post , we explored the growing pressures on OPEX in the telecom sector, from network upgrades and regulatory compliance to rising energy costs and cybersecurity. As telecom executives work to navigate these challenges, finding a balance between fostering innovation and managing operating expenses is no longer optional — it is a necessity for survival. In this blog, we’ll explore a powerful approach to achieving both in 2025: the concept of composable ERP, a…

Cyber threat actors are no longer just targeting hospitals with ransomware, they’re now infiltrating the very software that patients use to manage their care, installing backdoors that put sensitive medical information at risk. In a new report, researchers at Forescout’s Vedere Labs have found that Silver Fox, a recently identified Chinese-backed hacking group, was exploiting patient medical imaging software to deploy a backdoor, a keylogger and a crypto miner on victim computers. The targeted software…

Ransomware actors are largely eschewing encryption, with at least 80% of attacks last year focusing solely on exfiltrating data, as it is quicker and easier, according to ReliaQuest. The threat intelligence vendor claimed in its Annual Cyber-Threat Report that exfiltration-only ransomware attacks are 34% faster. After initial access, “breakout time” typically takes just 48 minutes, although some groups manage to achieve lateral movement in as little as 27 minutes, giving network defenders little time to…
