Acer has released a firmware update to address a security vulnerability that could be potentially weaponized to turn off UEFI Secure Boot on affected machines. Tracked as  CVE-2022-4020 , the high-severity vulnerability affects five different models that consist of Aspire A315-22, A115-21, and A315-22G, and Extensa EX215-21 and EX215-21G. The PC maker described the vulnerability as an issue that "may allow changes to Secure Boot settings by creating NVRAM variables." Credited with  discovering  the flaw is ESET researcher Martin Smolár, who previously disclosed  similar bugs  in Lenovo computers. Disabling Secure Boot, an integrity mechanism that guarantees that only trusted software is loaded during system startup, enables a malicious actor to tamper with  boot loaders , leading to severe consequences. This includes  granting  the attacker complete control over the operating system loading process as well as "disable or bypass protections t...

Threat actors are capitalizing on a popular TikTok challenge to trick users into downloading information-stealing malware, according to new research from Checkmarx. The trend, called  Invisible Challenge , involves applying a filter known as  Invisible Body  that just leaves behind a silhouette of the person's body. But the fact that individuals filming such videos could be undressed has led to a nefarious scheme wherein the attackers post TikTok videos with links to rogue software dubbed "unfilter" that purport to remove the applied filters. "Instructions to get the 'unfilter' software deploy  WASP stealer malware  hiding inside malicious Python packages," Checkmarx researcher Guy Nachshon  said  in a Monday analysis. The WASP stealer (aka W4SP Stealer) is a malware that's designed to steal users' passwords, Discord accounts, cryptocurrency wallets, and other sensitive information. The TikTok videos posted by the attackers, @learncyber an...

When the headlines focus on breaches of large enterprises like the Optus breach, it's easy for smaller businesses to think they're not a target for hackers. Surely, they're not worth the time or effort?  Unfortunately, when it comes to cyber security, size doesn't matter.  Assuming you're not a target leads to lax security practices in many SMBs who lack the knowledge or expertise to put simple security steps in place. Few small businesses prioritise cybersecurity, and hackers know it. According to Verizon, the number of smaller businesses being hit has climbed steadily in the last few years – 46% of cyber breaches in 2021 impacted businesses with fewer than 1,000 employees.  Cyber security doesn't need to be difficult Securing any business doesn't need to be complex or come with a hefty price tag. Here are seven simple tips to help the smaller business secure their systems, people and data. 1 — Install anti-virus software everywhere Every organisation has anti-vi...

Ireland's Data Protection Commission (DPC) has  levied fines  of €265 million ($277 million) against Meta Platforms for failing to safeguard the personal data of more than half a billion users of its Facebook service, ramping up privacy enforcement against U.S. tech firms. The fines follow an inquiry initiated by the European regulator on April 14, 2021, close on the heels of a leak of a "collated dataset of Facebook personal data that had been made available on the internet." This included the  personal information  associated with 533 million users of the social media platform, such as their phone numbers, dates of birth, locations, email addresses, gender, marital status, account creation date, and other profile details. Meta acknowledged that the information was "old data" that was obtained by malicious actors by taking advantage of a technique called "phone number enumeration" to  scrape users' public profiles . This entailed misusing a t...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday  added  a critical flaw impacting Oracle Fusion Middleware to its Known Exploited Vulnerabilities ( KEV ) Catalog, citing evidence of active exploitation. The vulnerability, tracked as  CVE-2021-35587 , carries a CVSS score of 9.8 and impacts Oracle Access Manager (OAM) versions 11.1.2.3.0, 12.2.1.3.0, and 12.2.1.4.0. Successful exploitation of the remote command execution bug could enable an unauthenticated attacker with network access to completely compromise and take over Access Manager instances. "It may give the attacker access to OAM server, to create any user with any privileges, or just get code execution in the victim's server," Vietnamese security researcher Nguyen Jang ( Janggggg ), who reported the bug alongside  peterjson ,  noted  earlier this March. The issue was addressed by Oracle as part of its  Critical Patch Update  in January 2022. Additional d...

Amazon Web Services (AWS) has resolved a cross-tenant vulnerability in its platform that could be weaponized by an attacker to gain unauthorized access to resources. The issue relates to a  confused deputy problem , a type of privilege escalation where a program that doesn't have permission to perform an action can coerce a more-privileged entity to perform the action. The shortcoming was reported by Datadog to AWS on September 1, 2022, following which a patch was shipped on September 6. "This attack abuses the AppSync service to assume [identity and access management]  roles  in other AWS accounts, which allows an attacker to pivot into a victim organization and access resources in those accounts," Datadog researcher Nick Frichette  said  in a report published last week. In a coordinated disclosure, Amazon  said  that no customers were affected by the vulnerability and that no customer action is required. It described it as a "case-sensitivity ...
