Patch management approaches that aren’t data-driven are breaches waiting to happen. Attackers are weaponizing years-old CVEs because security teams are waiting until a breach happens before they prioritize patch management.

Cyberattackers’ growing tradecraft now includes greater contextual intelligence about which CVEs are most vulnerable. The result: Manual approaches to patch management — or overloading endpoints with too many agents — leaves attack surfaces unprotected, with exploitable memory conflicts.

Distributed denial-of-service (DDoS) attacks are growing in frequency and sophistication, thanks to the number of attack tools available for a couple of dollars on the Dark Web and criminal marketplaces. Numerous organizations became victims in 2022, from the Port of London Authority to Ukraine’s national postal service.

Security leaders are already combating DDoS attacks by monitoring network traffic patterns, implementing firewalls, and using content delivery networks (CDNs) to distribute traffic across multiple servers. But putting more security controls in place can also result in more DDoS false positives — legitimate traffic that’s not part of an attack but still requires analysts to take steps to mitigate before it causes service disruptions and brand damage.

Rate limiting is often considered the best method for efficient DDoS mitigation: URL-specific rate limiting prevents 47% of DDoS attacks, according to Indusface’s “State of Application Security Q4 2022” report. However, the reality is that few engineering leaders know how to use it effectively. Here’s how to employ rate limiting effectively while avoiding false positives.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) warned today of a critical remote code execution (RCE) flaw in the Ruckus Wireless Admin panel actively exploited by a recently discovered DDoS botnet.

While this security bug (CVE-2023–25717) was addressed in early February, many owners are likely yet to patch their Wi-Fi access points. Furthermore, no patch is available for those who own end-of-life models affected by this issue.

Attackers are abusing the bug to infect vulnerable Wi-Fi APs with AndoryuBot malware (first spotted in February 2023) via unauthenticated HTTP GET requests.

Intro

In February 2022, Microsoft disabled VBA macros on documents due to their frequent use as a malware distribution method. This move prompted malware authors to seek out new ways to distribute their payloads, resulting in an increase in the use of other infection vectors, such as password-encrypted zip files and ISO files.

MSI suffered a major data breach, but it’s not the only company impacted — all Intel users may be at risk.

Over the past year, SideWinder has been linked to a cyber attack aimed at Pakistan Navy War College (PNWC) as well as an Android malware campaign that leveraged rogue phone cleaner and VPN apps uploaded to the Google Play Store to harvest sensitive information.

The latest infection chain documented by BlackBerry mirrors findings from Chinese cybersecurity firm QiAnXin in December 2022 detailing the use of PNWC lure documents to drop a lightweight. NET-based backdoor (App.dll) that’s capable of retrieving and executing next-stage malware from a remote server.

What makes the campaign also stand out is the threat actor’s use of server-based polymorphism as a way to potentially sidestep traditional signature-based antivirus (AV) detection and distribute additional payloads by responding with two different versions of an intermediate RTF file.

Meta on Wednesday warned that hackers are using the promise of generative artificial intelligence like ChatGPT to trick people into installing malicious code on devices.

Over the course of the past month, security analysts with the social-media giant have found malicious software posing as ChatGPT or similar AI tools, chief information security officer Guy Rosen said in a briefing.

“The latest wave of malware campaigns have taken notice of generative AI technology that’s been capturing people’s imagination and everyone’s excitement,” Rosen said.
