Cyber Attacks

New Phishing Attack Uses Clever Microsoft Office Trick to Deploy NetSupport RAT

A new phishing campaign is targeting U.S. organizations with the intent to deploy a remote access trojan called NetSupport RAT. Israeli cybersecurity company Perception Point is tracking the activity under the moniker Operation PhantomBlu. “The PhantomBlu operation introduces a nuanced exploitation method, diverging from NetSupport RAT’s typical delivery mechanism by leveraging OLE (Object Linking and Embedding) template manipulation, exploiting Microsoft Office document templates to execute malicious code while evading detection,” security researcher Ariel Davidpur said.

Hackers Using Cracked Software on GitHub to Spread RisePro Info Stealer

Cybersecurity researchers have found a number of GitHub repositories offering cracked software that are used to deliver an information stealer called RisePro. The campaign, codenamed gitgub, includes 17 repositories associated with 11 different accounts, according to G DATA. The repositories in question have since been taken down by the Microsoft-owned subsidiary. “The repositories look similar, featuring a README.md file with the promise of free cracked software,” the German cybersecurity company said. “Green and red circles are commonly used on Github to display the status of automatic builds. Gitgub threat actors added four green Unicode circles to their README.md that pretend to display a status alongside a current date and provide a sense of legitimacy and recency.”

1 in 4 Organizations Shut Down OT Operations Due to Cyberattacks: Survey

A survey commissioned by Palo Alto Networks shows that many industrial organizations experience cyberattacks, and in a significant percentage of cases they lead to OT operations getting shut down. The survey was conducted in December 2023 and it targeted nearly 2,000 respondents from across 16 countries in the Americas, Europe and the APAC region. Three-quarters of respondents said they had detected malicious cyber activity in their OT environment, and 24% said they were forced to shut down OT operations due to a successful attack in the past year, either because of actual disruption or as a preemptive measure.
