Posted by in categories: business, cybercrime/malcode

The threat actors associated with the Gootkit malware have made “notable changes” to their toolset, adding new components and obfuscations to their infection chains.

Google-owned Mandiant is monitoring the activity cluster under the moniker UNC2565, noting that the usage of the malware is “exclusive to this group.”

Gootkit, also called Gootloader, is spread through compromised websites that victims are tricked into visiting when searching for business-related documents like agreements and contracts via a technique called search engine optimization (SEO) poisoning.

Researchers Discover New PlugX Malware Variant Spreading via Removable USB Devices

Posted by in category: cybercrime/malcode

Cybersecurity researchers have uncovered a PlugX sample that employs sneaky methods to infect attached removable USB media devices in order to propagate the malware to additional systems.

“This PlugX variant is wormable and infects USB devices in such a way that it conceals itself from the Windows operating file system,” Palo Alto Networks Unit 42 researchers Mike Harbison and Jen Miller-Osborn said. “A user would not know their USB device is infected or possibly used to exfiltrate data out of their networks.”

The cybersecurity company said it uncovered the artifact during an incident response effort following a Black Basta ransomware attack against an unnamed victim. Among other tools discovered in the compromised environment include the Gootkit malware loader and the Brute Ratel C4 red team framework.

After Google Docs, hackers turn to Microsoft OneNote to target users with malware

Posted by in categories: cybercrime/malcode, finance

Cyber attackers around the world are looking at alternate file attachment types to trap users with phishing and malware attacks, according to a report by Bleeping Computer. The alternate attachment types come in the form of online, open-source file attachments, and the latest type that has now been spotted includes Microsoft OneNote files. According to the report, hackers are exploiting OneNote attachments in emails to trick users into downloading malware.

The report stated that hackers switched to OneNote, Microsoft’s online note-taking alternative to Word, after the company disabled ‘macros’ by default in email attachments. The latter, which refer to code snippets that execute a command upon a user opening the email attachment, were long since used by attackers to get users to download malware attachments.

By using macros, hackers would store malware within Microsoft Word or Excel documents. Once a user opened the attachment, the malware would get triggered automatically. These malware, in turn, could be used for a wide range of attacks — including remote code execution, botnets, financial or identity theft, or even spyware.

Scammers posed as tech support to hack employees at two US agencies last year, officials say

Posted by in categories: cybercrime/malcode, government

Cybercriminals hacked employees of at least two US federal civilian agencies last year as part of a “widespread” fraud campaign that sought to steal money from individuals’ bank accounts, US cybersecurity officials revealed Wednesday.

In one case, the unidentified hackers posed as tech support, convinced a federal employee to call them and then instructed the federal employee to visit a malicious website, according to the advisory from the US Cybersecurity and Infrastructure Security Agency, National Security Agency and a threat-sharing center for state and local governments known as MS-ISAC.

The goal of the scam, which appears to have hit both private sector and government agencies, was to trick victims into sending the scammers money. It was unclear if that happened in the case of the federal employees.
