Next-generation Microsoft Teams will offer more powerful features ever needed
End-to-end encryption for voice and video calls on Facebook Messenger is now available, ensuring that no one else, even the Facebook team, can listen in on your conversations.
Video and audio calls are now as secure as one-to-one text chats, which have been encrypted end-to-end since 2016. (Although you do need to use the secret conversation feature for it to be enabled).
“People want their messaging applicationsÂ developed byÂ app developersÂ to be secure and private,” says RuthÂ Kricheli, Director of Product Management at Facebook Messenger. “With these new capabilities, we’re providing customers greater discretion over how private they want their calls and conversations to be.”Â
More features will be added soon
Facebook is also beginning to test end-to-end encryption for group conversations in Messenger and direct messaging in Instagram, albeit only a small number of users will have access to these features for the time being.

Five different defects in Dell’s DBUtil BIOS driver have been discovered.
After a security researcher discovered that the driver in question could be abused by an attacker to gain increased system privileges, Dell has released a patch that addresses multiple vulnerabilities in its DBUtil BIOS driver.
SentinelLabs security researcher Kasif Dekel discovered the vulnerable driver, and the team informed the PC giant of its findings in December of last year. The driver has been vulnerable since 2009, according to the US-based cybersecurity firm, though there is no evidence that its flaws have been exploited in the wild at this time.
The DBUtil BIOS driver is pre-installed on many Dell Windows laptops and desktops and is in charge of Dell Firmware Updates via the Dell BIOS Utility. It is estimated that the vulnerable driver was distributed to hundreds of millions of devices by the company via BIOS updates.
There are five distinct flaws.
Dekel discovered a collection of five flaws in the DBUtil driver, currently tracked as CVE-2021-21551 by Dell, that can be exploited to â€śescalate privileges from non-administrator users to kernel mode privileges.â€ť
Two of the five flaws discovered in Dell’s driver are memory corruption issues, two are security failures caused by a lack of input validation, and one is a logic flaw that could potentially be exploited to cause a denial-of-service.
In addition to discovering these flaws, Dekel has developed Proof-of-Concept (PoC) code, which he plans to release on June 1 to allow Dell users time to apply the company’s patch.
Dekel explained Sentinel Lab’s decision to make its research public in a new blog post, saying:
â€śWhile we have not seen any evidence that these vulnerabilities have been exploited in the wild as of yet, with hundreds of millions of enterprises and users currently vulnerable, it is unavoidable that attackers will seek out those who do not take the necessary precautions. Our motivation for publishing this research is to assist not only our customers, but also the community, in understanding the risk and taking appropriate precautions.
Users should review Dell’s latest advisory and FAQ document, which contain remediation instructions for these flaws. Users should, as Dekel mentioned, install Dell’s updated DBUtil driver as soon as possible to avoid falling victim to any potential attacks attempting to exploit these security flaws.
Why use third-party cookies when first-party data is available
As Google Chrome and other browsers prepare to end support for third-party cookies, Adobe announced the next-generation real-time customer data platform (CDP) to help brands activate known and unknown customer data.
The company’s real-time CDP allows brands to manage the entire customer profile and run seamlessly in one system without the need for third-party cookies.
As consumers become more aware of the value of the data they share online, privacy regulations such as GDPR become more and more complex.
However, at the same time, organizations are still committed to providing personalized brand experiences, usually created by tracking them from third-party cookies.
Now that Google has introduced its new tracking technology in Chrome, brands will reduce the knowledge of unknown visitors about their digital assets, which will damage their ability to provide compelling customer experiences.
Adobe Real-Time CDP
Adobe’s real-time CDP provides brands with a centralized hub that combines different types of first-party event and attribute data to help them understand their customers more completely.
The platform allows brands to combine first-party networks, applications, and media data from publishers to build richer customer profiles. They can then use Adobe Target to create a personalized experience for visitors.
As it becomes increasingly difficult for unknown visitors to use their email or phone number to register on a brandâ€™s website, Adobe Real-time CDP allows brands to build profiles of potential customers based on brand interaction.
This data will then be ingested by Adobe Target and used to arrange the next best content, offer or experience for them.
Adobe has also added a new feature called “segment matching” to its platform, which allows brands to expand their first-party data through partnerships.
On the other hand, lookalike audience segments allow the brand to identify other customers with similar attributes to the most well-known customers.
Through Adobe Real-time CDP, we work with brands to provide relevant, responsive and respectable through first-party data Experience.”
Brands interested in testing Adobe Real-time CDP on their own can request a demonstration of Adobe Experience Cloud on the company’s website.
