Cybersecurity spar between Biden and Putin at Geneva summit

Ransomware attacks were one of the main points of discussion that took place between Biden and Putin at Geneva. It was the first in-person summit for these presidents. At his speech after the end of the three-hour meeting with Baiden, Putin denied Russia’s support for ransomware groups and, generally, refused to answer any questions somehow connected to cyberattacks. Although Biden did not specify any details of his meeting with Putin, he noted that the topic related to ransomware attacks was actively discussed during the meeting. 

Biden provided Putin with the list containing the 16 specific entities defined as the objects of critical infrastructure that should be off-limits to attack. These entities represent such sectors as chemical, communications, defense industrial base, emergency, energy, financial services, etc. The G7 countries issued the statement calling Russia to fight against malicious groups responsible for committing ransomware attacks located on its territory. This summit confirms that the matter of cybersecurity is now included in the agenda of global leaders.

Over a billion CVS Health records exposed online

The key reason behind the exposure of data was the misconfiguration of cloud services that impacted security. The online database belonging to CVS Health was not protected by any password as well as did not have any authentication barriers to prevent unauthorized entry. The records found by WebsitePlanet together with researcher Jeremiah Fowler were connected to the US pharmaceutical and healthcare giant that is the owner of such brands as Aetna and CVS Pharmacy. The 204 GB database contained such information as visitor IDs, device access information, session IDs, and other data.

The information contained in the database may be used to carry out targeted phishing campaigns. Also, the giant’s competitors may be also interested in viewing the exposed data to gain competitive advantages. According to CVS Health, the unnamed vendor was managing the database.

$30,000 bounty paid by Facebook for exploit exposing private Instagram content

The researcher awarded by  Facebook reported the company on the vulnerability in the privacy features of Instagram. The vulnerable points in Instagram could have allowed malicious actors to view private media such as archived posts, stories, and reels on the platform without even following the targeted page. By obtaining the Media ID of the target user, attackers could send a POST request to Instagram’s GraphQL endpoint. As a result, display URLs and image URLs as well as like and save counts were exposed.

Attackers could extract sensitive data without being accepted as a follower, thereby, one of the main features of Instagram designed to ensure privacy of users did not perform its key function. Also, the endpoints could be used by malicious actors to extract the addresses of users’ Facebook pages that were linked to Instagram accounts. Bug bounty hunter Mayur Fartade reported his findings regarding the Instagram vulnerabilities within the framework of Facebook Bug bounty program on April 16. The vulnerable endpoints were patched by Facebook on 29 April.
