India's computer and emergency response team, CERT-In, on Thursday published new guidelines that require service providers, intermediaries, data centers, and government entities to compulsorily report cybersecurity incidents, including data breaches, within six hours. "Any service provider, intermediary, data center, body corporate and Government organization shall mandatorily report cyber incidents to CERT-In within six hours of noticing such incidents or being brought to notice about such incidents," the government said in a release.
OpenSSL has released a security update to address a vulnerability in the library that, if exploited, activates an infinite loop function and leads to denial of service conditions. Certificates causing DoS. In this case, the high-severity OpenSLL problem lies in a bug on the BN mod sqrt() function, that if served a maliciously crafted certificate to parse, it will enter an infinite loop.
As Ukraine fights for survival against invading Russian forces, here's a taste of some of the malware the nation's Computer Emergency Response Team is battling. To start, the team earlier this month said miscreants had spammed out emails impersonating government agencies containing links to fake Windows antivirus updates.
A bug in OpenSSL certificate parsing leaves systems open to denial-of-service attacks from anyone wielding an explicit curve. The vulnerability stems from a bug in the BN mod sqrt() function, which the OpenSSL team said is used to parse certificates that "Contain elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point encoded in compressed form." As it turns out, all you need to do to trigger an infinite loop in BN mod sqrt() is hand an OpenSSL-based application or service a certificate with invalid explicit curve parameters.
Russia is offering its own trusted Transport Layer Security certificate authority to replace certificates that need to be renewed by foreign countries. According to a notice on Russia's public service portal, Gosuslugi, as shown in a translated version in this article's featured art, the certificates will replace foreign security certs if they expire or get yanked by foreign CAs.
Moscow has set up its own certificate authority to issue TLS certs to Russians affected by sanctions or otherwise punished for president Putin's invasion of Ukraine. A notice on the government's unified public service portal states that the certificates will be made available to Russian websites unable to renew or obtain security certificates as a knock-on effect of Western sanctions and organizations refusing to support Russian customers.
Ukraine's Computer Emergency Response Team warned of new phishing attacks aimed at its citizens by leveraging compromised email accounts belonging to three different Indian entities with the goal of compromising their inboxes and stealing sensitive information. "In this way, they gain access to the email inboxes of Ukrainian citizens."
Two of Nvidia's code-signing certificates were part of the Feb. 23 Lapsus$ Group ransomware attack the company suffered - certificates that are now being used to sign malware so malicious programs can slide past security safeguards on Windows machines. Security researchers noted last week that binaries that hadn't been developed by Nvidia, but which had been signed with its stolen certificate to come off like legitimate Nvidia programs, had appeared in the malware sample database VirusTotal.
Ransomware remains a prime threat, putting millions of organizations at risk. An analysis of the rise in major threats is made available in the Agency's 2021 Annual Threat Landscape report.
Microsoft says Samsung devices enrolled in Microsoft Intune using a work profile will experience email and VPN connectivity issues due to missing certificates after upgrading to Android 12. Microsoft Intune is a cloud-based service designed to help admins manage Windows, macOS, iOS/iPadOS, and Android apps and devices in enterprise environments.
