Malware devs trick Windows validation with malformed certs
2021-09-23 16:24

Google researchers spotted malware developers creating malformed code signatures seen as valid in Windows to bypass security software. Roughly a month ago, Google Threat Analysis Group security researcher Neel Mehta discovered that the developers of an unwanted software known as OpenSUpdater started signing their samples with legitimate but intentionally malformed certificates, accepted by Windows but rejected by OpenSSL. By breaking certificate parsing for OpenSSL, the malicious samples would not be detected by some security solutions that use OpenSSL-powered detection rules and allowed to perform their malicious tasks on victims' PCs. "Since mid-August, OpenSUpdater samples have carried an invalid signature, and further investigation showed this was a deliberate attempt to evade detection," Mehta said.

Indonesian President's COVID jab cert leaks – authorities argue that's perfectly reasonable

Indonesian authorities have admitted that the COVID-19 vaccination certificate of the nation's President has circulated online and tried to explain that it's an indication of admirable transparency, rather than lamentable security. In one camp are those who argue that the document's unplanned public debut is more evidence that Indonesia's government is bad at securing information.

OpenSSL shuts down two high-severity bugs: Flaws enable cert shenanigans, denial-of-service attacks
2021-03-25 20:28

Two high-severity vulnerabilities in the OpenSSL software library were disclosed on Thursday alongside the release of a patched version of the software, OpenSSL 1.1.1k. OpenSSL is widely used to implement the Transport Layer Security and Secure Sockets Layer protocols, which support encrypted network connections. "In order to be affected, an application must explicitly set the X509 V FLAG X509 STRICT verification flag and either not set a purpose for the certificate verification or, in the case of TLS client or server applications, override the default purpose," the OpenSSL advisory explains.

It's not easy being green: EV HTTPS cert seller Sectigo questions Chrome's logic in burying EV HTTPS cert info
2021-03-03 11:45

Sectigo's chief compliance officer has hit out at Google for minimizing the visibility of Extended Validation HTTPS certificates in Chrome. In a chat with The Register, Sectigo CCO Tim Callan said his biz, which among other things is one of the biggest sellers of EV HTTPS certificates, was "Going to remove street and postal information from all of our public sites," seeing as Google thinks no one cares where a business is based.

Let's Encrypt completes huge upgrade, can now rip and replace 200 million security certs in 'worst case scenario'
2021-02-15 11:41

Internet Security Research Group nonprofit Let's Encrypt has massively upgraded its certification hardware and software so that it can delete and reissue all its certs in less than 24 hours. Last April the certificate authority was forced to kill three million HTTPS certs after a bug was found in its automated certificate management environment, about 2.6 per cent of its 150 million live certificate base.

Spanish banished: Google Chrome to snub Camerfirma for lax cert management
2021-02-02 08:02

When Google Chrome 90 arrives in April, visitors to websites that depend on TLS server authentication certificates from AC Camerfirma SA, a digital certificate authority based in Madrid, Spain, will find that those sites no longer present the secure lock icon. Mozilla, maker of Chrome rival Firefox, has been trying to decide whether Camerfirma's history of questionable certificate management practices - documented in a lengthy list - warrants banishing the Spanish company's certificates from its Root Store - the set of certificates Firefox recognizes as trustworthy by default.
