Podcast Summary: CyberWire Daily – “SSH-attered Trust”
Release Date: April 18, 2025
Host: Dave Bittner
Published by: N2K Networks
1. Critical Vulnerability in Erlang OTP SSH
At the outset of the episode, Dave Bittner highlights a severe security flaw in the Erlang OTP SSH implementation. This vulnerability, rated with a maximum CVSS score of 10, allows unauthenticated remote code execution on affected devices.
Key Details:
- Affected Systems: Widely used in high-availability systems such as telecommunications, IoT, and embedded devices.
- Exploit Mechanism: Improper handling of pre-authentication SSH messages permits attackers to execute commands as root via the SSH daemon.
- Recommendation: Immediate upgrading is urged. For systems where patching isn't feasible, restricting access to trusted IPs or disabling SSH entirely is advised.
Quote:
“The flaw stems from improper handling of pre authentication SSH messages, enabling attackers to run commands often as root, via the SSH daemon.” – Linda Gray Martin [02:00]
2. Bipartisan Effort to Renew Cybersecurity Information Sharing Act
Senators Gary Peters (D-Michigan) and Mike Rounds (R-South Dakota) are spearheading the renewal of the Cybersecurity Information Sharing Extension Act. This bipartisan initiative aims to extend a crucial 2015 law that facilitates the sharing of cyber threat data between businesses and the government.
Key Points:
- Purpose: Encourages companies to report threats like malware and vulnerabilities to the Department of Homeland Security (DHS) while providing legal protections.
- Impact: Enhances real-time collaboration between private firms and agencies such as CISA, aiding responses to major incidents like SolarWinds.
- Expert Opinion: The renewal presents an opportunity to update the law to address modern challenges related to privacy, supply chains, and evolving threats.
Quote:
“Senator Rounds warned that letting it lapse would harm national cyber defenses.” – Dave Bittner [04:30]
3. Newly Discovered Linux Kernel Vulnerability
A newly identified vulnerability in the Linux kernel poses a significant risk by allowing local attackers to escalate privileges and potentially gain root access.
Key Details:
- CVSS Score: 7.8
- Affected Component: Bitmap IP set type in the netfilter subsystem.
- Exploit Mechanism: Allows out-of-bounds writes, bypassing castler, and executing kernel-level code.
- Recommendation: System administrators are strongly urged to apply available patches immediately to mitigate the risk.
Quote:
“The exploit code enables attackers to perform out of bounds writes, bypass castler, and execute kernel level code.” – Linda Gray Martin [05:15]
4. Risky Chrome Extensions Uncovered
Security researcher John Tuckner has identified 57 Chrome extensions deemed risky, collectively serving around 6 million users. These extensions often request excessive permissions and have the potential for surveillance or malicious activities.
Key Concerns:
- Functionality: Extensions claiming to offer privacy or ad-blocking can monitor browsing behavior, access cookies, modify search results, and execute remote scripts.
- Notable Example: The "Fire Shield" extension was found to be heavily obfuscated and communicates with suspicious domains.
- Action Taken: Google is investigating, and users are advised to remove flagged extensions and reset passwords as a precaution. Some extensions have already been removed from the Chrome Web Store.
Quote:
“These extensions, often unlisted from the Chrome Web Store and only installable via direct link, claim to offer privacy or ad blocking services but can monitor browsing behavior.” – Linda Gray Martin [06:45]
5. Strela Stealer Malware Campaigns
Strela Stealer, a credential-stealing malware targeting email clients like Microsoft Outlook and Mozilla Thunderbird, has been active since 2022. Attributed to threat actor Hive0145, recent campaigns have intensified with improved obfuscation and new delivery methods.
Campaign Highlights:
- Distribution: Phishing emails containing zip files with malicious JavaScript that downloads a DLL payload.
- Recent Activity: Over 100 organizations across Europe and the US targeted with enhanced delivery methods involving PowerShell and WebDAV.
- Defense Measures: AttackIQ has released simulations to help organizations test and strengthen their defenses against Strela Stealer.
Quote:
“Attackers use stolen credentials in nearly nine out of 10 data breaches.” – Dave Bittner [08:00]
6. Legends International Data Breach
Legends International, a prominent live events service provider, has informed employees and customers about a data breach identified in November. The breach exposed sensitive information, including Social Security numbers, driver's licenses, payment card details, and medical records of over 8,000 Texans.
Key Points:
- Response: Systems were taken offline upon discovery, and affected individuals are offered two years of free identity protection.
- Legal Outcome: The airport retailer has agreed to a $6.9 million settlement to resolve a class action lawsuit related to the breach.
- Attribution: No group has claimed responsibility for the attack.
Quote:
“The company took systems offline and found that attackers exfiltrated files containing sensitive data.” – Linda Gray Martin [10:00]
7. CISA Warning on Actively Exploited SonicWall Vulnerability
The Cybersecurity and Infrastructure Security Agency (CISA) has issued a warning to US Federal agencies about a high-severity remote code execution vulnerability affecting SonicWall SMA100 series appliances.
Vulnerability Details:
- Impact: Allows low-privileged remote attackers to execute arbitrary code via the SMA 100 management interface.
- Status: Initially classified as a denial of service issue, it has been upgraded in severity after confirming active exploitation.
- Recommendation: Agencies must apply patches by May 7th, and all organizations are urged to act swiftly to prevent potential breaches.
Quote:
“CISA warns of an actively exploited SonicWall vulnerability.” – Dave Bittner [11:25]
8. Ransomware Settlement with Paradis Shops
Paradis Shops, an airport retailer, has agreed to a $6.9 million settlement to resolve a class action lawsuit following a 2020 ransomware attack. The breach compromised personal data of 76,000 current and former employees, including names and Social Security numbers.
Legal Proceedings:
- Allegations: Plaintiffs accused Paradis Shops of negligence and delayed notification post-breach.
- Resolution: The company chose to settle to avoid prolonged litigation, reflecting a growing trend of post-breach class action lawsuits.
Quote:
“Paradis opted to settle to avoid prolonged litigation.” – Linda Gray Martin [12:10]
