A security vulnerability discovered and patched 10 years ago has remained unaddressed in various Avaya phones until recently, McAfee security researchers have discovered.
In May 2019 (updated in June), F5 issued a security advisory about a potential injection issue in the Tool Command Language (TCL) as used with its BIG-IP load balancers. Load balancers are essential to ensure consistent web services in high volume circumstances, and BIG-IP is popular with banks, governments and large corporations.
Repurposing Mac malware is not a difficult task for someone with reverse-engineering skills, and it’s a far simpler approach compared to writing malware from scratch, a researcher has demonstrated.
Broadcom announced plans Thursday to buy the enterprise unit of cybersecurity firm Symantec Corp. for $10.7 billion in a move to further diversify the US semiconductor maker.
Malicious actors could use rogue engineering workstations to take control of Siemens programmable logic controllers (PLCs), and they can hide the attack from the engineer monitoring the system, researchers from two universities in Israel have demonstrated.
In the past, data protection regulation has largely been concerned with preventing the theft of personal data. Security and security products have focused on preventing breaches -- no breach effectively meant no failure of data protection compliance.
The growth of IoT devices has highlighted the difficulties in ensuring firmware security -- especially where the device and software are initially sourced from third parties, or developed under time pressures in-house. Now a new firmware analyzer has been released to open source on GitHub.
Researchers from security firm IOActive have discovered a series of vulnerabilities and attacks that they believe could be possible on Boeing's 787 Dreamliner.
The Australian Cyber Security Centre (ACSC) has released an advisory on password spraying attacks. Password spraying is a type of brute-force attack in which a malicious actor uses a single password against targeted user accounts before moving on to attempt a second password, and so on. This technique allows the actor to remain undetected by avoiding rapid or frequent account lockouts.
The ACSC provides recommendations for organizations to detect and mitigate these types of attacks against their external services, such as webmail, remote desktop access, or cloud-based services.
The Cybersecurity and Infrastructure Security Agency (CISA) encourages users and administrators to review the ACSC advisory on password spraying attacks and the following CISA tips:
• Choosing and Protecting Passwords
• Supplementing Passwords

The Cybersecurity and Infrastructure Security Agency (CISA) is aware of a vulnerability (CVE-2019-1125) known as SWAPGS, which is a variant of Spectre Variant 1—that affects modern computer processors. This vulnerability can be exploited to steal sensitive data present in a computer systems' memory.
Spectre is a flaw an attacker can exploit to force a program to reveal its data. The name derives from "speculative execution"—an optimization method a computer system performs to check whether it will work to prevent a delay when actually executed. Spectre affects almost all devices including desktops, laptops, and cloud servers.
CISA encourages users and administrators to review the following guidance, refer to their hardware and software vendors for additional details, and apply an appropriate patch when available:

In the wake of the recent shootings in El Paso, TX, and Dayton, OH, the Cybersecurity and Infrastructure Security Agency (CISA) advises users to watch out for possible malicious cyber activity seeking to capitalize on these tragic events. Users should exercise caution in handling emails related to the shootings, even if they appear to originate from trusted sources. Fraudulent emails often contain links or attachments that direct users to phishing or malware-infected websites. Emails requesting donations from duplicitous charitable organizations are also common after tragic events. Be wary of fraudulent social media pleas, calls, texts, donation websites, and door-to-door solicitations relating to these events.
To avoid becoming a victim of malicious activity, users and administrators should consider taking the following preventive measures:
Use caution when opening email attachments, and do not click on links in unsolicited email messages. Refer to CISA’s Tip on Using Caution with Email Attachments. Review CISA’s Tip on Staying Safe on Social Networking Sites. Refer to CISA’s Tip on Avoiding Social Engineering and Phishing Attacks. Review the information from the Federal Trade Commission on Before Giving to a Charity.This product is provided subject to this Notification and this Privacy & Use policy.
