HP has released its quarterly HP Wolf Security Threat Insights Report, highlighting the relentless pursuit of cyber adversaries to exploit vulnerabilities and infiltrate endpoints. The report reveals a range of tactics that attackers use, including the utilization of ad tools to enhance their campaigns and the shifting landscape from macros to Office exploits. These insights underscore the evolving nature of cybersecurity threats and the imperative for organizations to stay vigilant in safeguarding their digital assets.
Campaigns Uncovered by HP Wolf Security Threat Research Team
DarkGate Campaign Utilizes Ad Tools to Enhance Attacks:
- Malicious PDF attachments, disguised as OneDrive error messages, redirect users to sponsored content on a popular ad network, facilitating the distribution of DarkGate malware.
- Ad services enable threat actors to analyze click rates on different lures, aiding in the refinement of campaigns for maximum impact.
- CAPTCHA tools are employed by threat actors to evade sandbox scanning, ensuring only human clicks activate the malware.
- DarkGate malware grants cybercriminals backdoor access to networks, exposing victims to risks such as data theft and ransomware.
Shift from Macros to Office Exploits:
In Q4, a significant portion of intrusion attempts, with 84% involving spreadsheets and 73% involving Word documents, targeted vulnerabilities in Office applications, marking a departure from macro-enabled attacks.
However, macro-enabled attacks remain prevalent, especially in instances utilizing low-cost malware like Agent Tesla and XWorm.
Rise of PDF Malware:
11% of malware analyzed in Q4 utilized PDFs as a delivery mechanism, compared to just 4% in the first two quarters of 2023.
Notably, the WikiLoader campaign employed a counterfeit parcel delivery PDF to deceive users into installing Ursnif malware.
Discord and TextBin as Hosts for Malicious Files:
- Threat actors leverage legitimate file and text-sharing platforms like Discord and TextBin to disseminate malicious files.
- These platforms, trusted by organizations, evade anti-malware scanners, heightening the likelihood of attackers remaining undetected.
“Cybercriminals are becoming adept at getting into our heads and understanding how we work. For instance, the design of popular cloud services is always being refined, so when a fake error message appears, it won’t necessarily raise an alarm, even if a user hasn’t seen it before. With GenAI generating even more convincing malicious content at little-to-n******, distinguishing real from fake will only get harder.” – ALEX HOLLAND, Senior Malware Analyst in the HP Wolf Security threat research team
