Threat Intelligence Cybersecurity Hacking News

A new attack campaign compromising internet-connected devices has come to the notice of researchers. Propelled by Russian hackers, it infects devices with the TrueBot malware downloader, which drops Clop ransomware, Grace malware, and other malicious tools. Threats aimed at legal, legal, financial, and travel agencies in Europe and the Middle East peaked with an infamous hack-for-hire group eying to compromise systems using the Janicab malware. The hacker group has a proven track record of harvesting sensitive internal company data and email credentials.

Moving on, numerous vulnerable Pulse Connect Secure hosts were found to be lying in wait for security fixes, even for those released last year. Pulse Connect Secure appliances have been among the top targets of state-sponsored threat actors and other cybercriminal groups.
