Title: ‘Critical’ CUPS vulnerability chain easy to use for massive DDoS attacks

Feedly Summary: Also, rooting for Russian cybercriminals, a new DDoS record, sneaky Linux server malware and more
Infosec In Brief The critical vulnerability in the Common Unix Printing System (CUPS) reported last week might have required some very particular circumstances to exploit, but Akamai researchers are warning the same vulnerabilities can easily be exploited for mass DDoS attacks. …

AI Summary and Description: Yes

Summary: The text provides an overview of critical vulnerabilities in the Common Unix Printing System (CUPS) that can be exploited for DDoS attacks, along with insights into ongoing cyber threats from various malicious actors, including a financially motivated cybercrime gang using deepfake malware. Notably, it highlights a surge in DDoS attacks, particularly against financial services, and emphasizes the importance of patching systems to mitigate risks.

Detailed Description:
The text outlines significant vulnerabilities in the CUPS, warning of the potential for mass DDoS attacks if exploited. Akamai researchers indicate that over 198,000 devices are vulnerable, with around 58,000 especially susceptible to DDoS mischief. There’s also mention of a dramatic increase in DDoS attacks, with Cloudflare noting new record-high attacks they have had to mitigate.

Key points include:
– **CUPS Vulnerability**:
– Specific vulnerabilities in CUPS with CVEs that allow remote attacks if specific conditions are met, which could lead to DDoS.
– Exploitation can occur with minimal effort if the server treats malicious DDoS requests as legitimate print jobs.
– Akamai’s findings indicate a large number of potentially vulnerable servers, highlighting the urgency for system administrators to patch CUPS installations.

– **DDoS Attacks on the Rise**:
– Cloudflare reported a 46% increase in DDoS attacks during the first half of 2024.
– Record-breaking attacks (3.8 Tbps) targeted various industries, suggesting a shift towards more aggressive capabilities to exhaust bandwidth and resources efficiently.

– **Cyber Crime and Malicious Software**:
– North Korean hackers and their continued activities despite indictments, showcasing the complexities of international cyber law enforcement.
– The use of deepfake malware by the FIN7 cybercriminal group, which sets up honeypots under the guise of offering AI-generated content, underscores the risks associated with downloading malicious software.
– Emergence of “perfctl malware” designed to hijack Linux systems for cryptocurrency mining, showcasing the threat from widely prevalent malware that serves as an underground proxy.

– **Recommendations for Professionals**:
– Secure CUPS services and patch systems to avoid exploitation.
– Maintain vigilance against emerging DDoS threats and employ protective measures like cloud-based DDoS protection.
– Be aware of the ongoing risks posed by cybercriminals leveraging popular technology trends and ensure robust cybersecurity practices are in place.
