The Computer Emergency Response Team of Ukraine has issued an alert warning of cyber attacks against state authorities in the country that deploy a legitimate remote access software named Remcos. The bogus emails that kick-start the infection sequence claim to be from Ukrainian telecom company Ukrtelecom and come bearing a decoy RAR archive.
Most Windows-powered datacenter systems and applications remain vulnerable to a spoofing bug in CryptoAPI that was disclosed by the NSA and the UK National Cyber Security Center and patched by Microsoft last year, according to Akamai's researchers. The bug isn't a remote code execution flaw; it's a vulnerability that allows someone to pretend to be another to an application or operating system, in the context of identity and certificate cryptography checks on Windows.
Cert-manager adds certificates and certificate issuers as resource types in Kubernetes clusters and simplifies the process of obtaining, renewing, and using those certificates. Cert-manager is an open-source project that automates the issuance and renewal of X.509 certificates for cloud-native Kubernetes or OpenShift environments.
Italy's Computer Security Incident Response Team has disclosed recent DDoS attacks against crucial government sites in the country over the past couple of days. DDoS is an attack that aims to deplete a server's available resources, making it unable to respond to legitimate user requests and rendering the sites it hosts inaccessible.
The Computer Emergency Response Team of Ukraine has warned of phishing attacks that deploy an information-stealing malware called Jester Stealer on compromised systems. The mass email campaign carries the subject line "Chemical attack" and contains a link to a macro-enabled Microsoft Excel file, opening which leads to computers getting infected with Jester Stealer.
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.
