SuperFish fallout

Comodo PrivDog worse than SuperFish

The SuperFish software installed on Lenovo laptops that was discovered last week to use the same discoverable private key across all installations used a library called Komodia to accomplish this. Despite the similar name, Comodo is a different company and the problem with it's software is even worse. In the case of SuperFish, one can MiTM users by using the now known private SSL key. Additionally, PrivDog sends information about every site you visit, unencrypted, to an ad company.

In the case of Comodo's PrivDog software though, no SSL checks are performed at all, so you can use any private key you want. Comodo's main business is SSL certificates, but it also offers end-point protection software. Knowledge in either of those areas should have ensured they didn't do what they did.

Lavasoft also using Komodia

Lavasoft is another end-point protection company, and they were also found to be using the same libraries that resulted in the problems of SuperFish.

Analysis of old vulns

Newspaper news

  • Director of National Intelligence attributes Sands hack to Iran government: The Director of National Intelligence, James Clapper, made a testimony in front of the Senate Armed Services Committee, in which he attributed the hack on the Sands Las Vegas Corporation in 2014 to the Iranian government. Customer data such as credit card, social security numbers, and drivers license numbers were stolen, but the hackers also supposedly attempted to destroy data there.
  • SEC on the prowl for cyber security cases: Publicly traded companies must announce information related to major events that shareholders should know about in the form of what is called Form 8-K filings. For example, when JP Morgan was hacked, they released an 8-K. The SEC (which regulates the disclosures of publicly traded companies) is now on the prowl to investigate companies that have been breached to ensure they are disclosing information properly and have adequately protected their information in the first place.
  • Security breach at Uber: The driving service Uber had a breach that exposed info about 50,000 drivers.

Other reads

  • Kizzle: A Signature Compiler for Exploit Kits: Academic paper from Microsoft about automatically generating signatures for javascript exploit kits by clustering them and then generating regular expressions that can match all elements within the cluster. The signatures produced by Kizzle have a false positive rate under 0.3% and false negatives are under 5%. It takes 90 minutes to do the clustering and generate the signatures. Although Kizzle can generate signatures for known exploit kits, it must first be told what exploit kits to detect and be given samples of them.
  • Advisory: Seagate NAS Remote Code Execution Vulnerability: Multiple vulnerabilities in Seagate NAS devices. Some due to old software with known vulns, some due to their custom software. After 130 days from advising the company initially, the researcher released details once Seagate said they would not be updating it. There are 2500 devices visible from Shodan.
