Apple accidentally notarized malware on macOS

The malware was initially discovered by college student Peter Dantini and passed on to security researcher Patrick Wardle. The campaign was distributing the “Shlayer” adware, and its unclear how the malware got past Apples checks and software scanning. Wardle notified Apple on August 28th, and the company subsequently revoked the notarizations the same day. However Wardle noticed on August 30th the malware was still being distributed, but notarized from a different developer account, and notified Apple of the update. In February, Apple began requiring all apps to be notarized to run on macOS.

Mozilla find out “Why We Still Can’t Browse in Peace”

A study by three Mozilla employees found that most internet users have unique browsing habits that can allow advertisers to track and re-identify users across different sets of user data that contain browsing history. The study found that a list of between 50 to 150 of a user’s most accessed domains were enough to create a profile. The study was a follow up to a 2012 study, and found that unique browsing histories have become more common, with reidentifiability of a user increasing from 38% to 50% using just 50 domains in a browser history.

Cloud misconfiguration woes continue

AppOmni CEO Brendan O’Connor wrote a piece looking at the cost of cloud misconfiguration for enterprises. He points to the fact that misconfigurations are the root cause to most of the 33.4 billion records exposed in cloud breaches over the last two years. Part of this is due to a misunderstanding in the cloud that cloud vendors are responsible for the security of the cloud, but customers bear responsibility for security once in the cloud. With mass work from home as the result of COVID-19, he points to the need to evaluate change controls, review APIs as a threat surface, establish an explicit cloud architecture and strategy, and institute identity, credential, and access management systems to ultimately help solve the configuration problem.

Internet outage hits several security services

The outage was caused by an apparent misconfiguration or hardware failure across an internet backhaul connection, impacting CenturyLink, OpenDNS, Duo Security, Cloudflare, and Imperva among others on August 30th. Typically when a network can’t handle traffic, it simply routes to another network able to handle the load, but the affected network did not withdraw routes once a customer was disconnected. The affected network belonged to Level 3, which was acquired by CenturyLink in 2016. (InfoSec Handlers Diary)
