Researchers Warn of Critical Security Bugs in Schneider Electric Modicon PLCs

Security researchers have disclosed two new vulnerabilities affecting Schneider Electric Modicon programmable logic controllers (PLCs) that could allow for authentication bypass and remote code execution. The flaws, tracked as CVE-2022-45788 (CVSS score: 7.5) and CVE-2022-45789 (CVSS score: 8.1), are part of a broader collection of security defects tracked by Forescout as OT:ICEFALL. Successful

Critical Bug in Siemens SIMATIC PLCs Could Let Attackers Steal Cryptographic Keys

A vulnerability in Siemens Simatic programmable logic controller (PLC) can be exploited to retrieve the hard-coded, global private cryptographic keys and seize control of the devices. "An attacker can use these keys to perform multiple advanced attacks against Siemens SIMATIC devices and the related TIA Portal, while bypassing all four of its access level protections," industrial cybersecurity

Hacktivist Group GhostSec Compromises 55 Berghof PLCs Across Israel

A hacktivist collective called GhostSec has claimed credit for compromising as many as 55 Berghof programmable logic controllers (PLCs) used by Israeli organizations as part of a "Free Palestine" campaign. Industrial cybersecurity firm OTORIO, which dug deeper into the incident, said the breach was made possible owing to the fact that the PLCs were accessible through the Internet and were

New Evil PLC Attack Weaponizes PLCs to Breach OT and Enterprise Networks

Cybersecurity researchers have elaborated a novel attack technique that weaponizes programmable logic controllers (PLCs) to gain an initial foothold in engineering workstations and subsequently invade the operational technology (OT) networks. Dubbed "Evil PLC" attack by industrial security firm Claroty, the issue impacts engineering workstation software from Rockwell Automation, Schneider

Hackers Distributing Password Cracking Tool for PLCs and HMIs to Target Industrial Systems

Industrial engineers and operators are the target of a new campaign that leverages password cracking software to seize control of Programmable Logic Controllers (PLCs) and co-opt the machines to a botnet. The software "exploited a vulnerability in the firmware which allowed it to retrieve the password on command," Dragos security researcher Sam Hanson said. "Further, the software was a malware
