Yandex | Breaking Cybersecurity News | The Hacker News

Russian internet giant Yandex has been the target of a record-breaking distributed denial-of-service (DDoS) attack by a new botnet called Mēris. The botnet is believed to have pummeled the company's web infrastructure with millions of HTTP requests, before hitting a peak of 21.8 million requests per second (RPS), dwarfing a recent botnet-powered attack that came to light last month,  bombarding  an unnamed Cloudflare customer in the financial industry with 17.2 million RPS. Russian DDoS mitigation service Qrator Labs, which disclosed details of the attack on Thursday, called  Mēris  — meaning "Plague" in the Latvian language — a "botnet of a new kind."  "It is also clear that this particular botnet is still growing. There is a suggestion that the botnet could grow in force through password brute-forcing, although we tend to neglect that as a slight possibility. That looks like some vulnerability that was either kept secret before the massive campaign...

Russian Dutch-domiciled search engine, ride-hailing and  email service provider Yandex on Friday disclosed a data breach that compromised 4,887 email accounts of its users. The company blamed the incident on an unnamed employee who had been providing unauthorized access to the users' mailboxes for personal gain. "The employee was one of three system administrators with the necessary access rights to provide technical support for the service," Yandex said in a statement. The company said the security breach was identified during a routine audit of its systems by its security team. It also said there was no evidence that user payment details were compromised during the incident and that it had notified affected mailbox owners to change their passwords. It's not immediately clear when the breach occurred or when the employee began offering unauthorized access to third-parties. "A thorough internal investigation of the incident is under way, and Yandex will be...

Not every security vulnerability is high risk on its own - but in the hands of an advanced attacker, even small weaknesses can escalate into major breaches. These five real vulnerabilities, uncovered by Intruder's bug-hunting team, reveal how attackers turn overlooked flaws into serious security incidents. 1. Stealing AWS Credentials with a Redirect Server-Side Request Forgery (SSRF) is a common vulnerability that can have a significant impact, especially in cloud-hosted applications. If a web application fetches resources from user-supplied URLs, care should be taken to ensure attackers can't manipulate requests to access unintended resources. While assessing a home-moving app running in AWS, our team tested common SSRF bypass techniques. The attack chain was as follows: the app sent a webhook request to the attacker's web server, which responded with a 302 redirect to AWS's metadata service. The app followed the redirect and logged the response, which exposed sensitive metadat...
