Varo Office-tiedostoja jo esi­katselu voi olla vaarallista

www.is.fi/digitoday/tietoturva/art-2000008260361.html Microsoftin Office-asiakirjoissa, eli Wordilla, Excelillä ja PowerPointilla tehdyissä tiedostoissa piilee luultua suurempi vaara, kertovat muun muassa Traficomin Kyberturvallisuuskeskus sekä Kaspersky Lab. Aiemmin kerrottiin, että Windowsiin kuuluvassa MSHTML-nimisessä ohjelmistokomponentissa oleva haavoittuvuus mahdollistaa haittaohjelman ujuttamisen tietokoneelle Office-asiakirjan mukana. Tällöin uskottiin haittaohjelman aktivoitumisen edellyttävän asiakirjan avaamista ja suojausvaroituksen klikkaamista. Nyt on käynyt ilmi, että nimellä CVE-2021-40444 tunnettu haavoittuvuus on oletettua pahempi. Onnistuneeseen hyökkäykseen riittää se, että vastaanottaja esikatselee saastutettua asiakirjaa. Lopputuloksena hyökkääjä pääsee suorittamaan omia ohjelmiaan uhrin tietokoneella. Haavoittuvuutta käytetään jo hyväksi hyökkäyksiin.

Open redirect on UK council website was being used for Royal Mail-themed parcel payments scam

www.theregister.com/2021/09/13/open_redirect_council_property_website_spam/ An open redirect on a UK council-backed property website allowed low-level miscreants to evade filters. The website operated by tech services biz Civica had an open redirect being actively abused by spammers, piggybacking off the website’s domain authority so their messages weren’t flagged up by scanning tools. Fortuitously, one of the spam emails that bounced through the Homes4Wiltshire website ended up in the mailbox of ethical hacker Scott Helme, who was intrigued enough to track down how it had got through his defences. The message itself was a Royal Mail-themed spam campaign urging Helme to pay for a delivery a very familiar scam from the past couple of years. On clicking the “proceed now” button in the email, he saw it linked to Homes4Wiltshire’s website and traced the full number of hops back to a domain called package-royamail[.]co[.]uk. (Did you spot the missing L? Plenty wouldn’t have.). Helme blogged about his detective work tracking down the root cause of the redirect, which he attributed to a configuration problem in a web app deployed by Civica to its customers’ websites. Some brief Google-enabled sleuthing helped him find other domains using the same unique ViewSwitcherSwitchView?mobile=True&returnUrl= string.

This is how a cybersecurity researcher accidentally broke Apple Shortcuts

www.zdnet.com/article/this-is-how-a-cybersecurity-researcher-accidentally-broke-apple-shortcuts/#ftag=RSSbaffb68 A Detectify researcher has explained how an investigation into Apple CloudKit led to the accidental downtime of Shortcuts functionality for users. In March, Apple users began to report error messages when they attempted to open shared shortcuts. As noted by 9to5Mac, this bizarre issue was of particular concern to content creators who shared shortcuts with their followers via iCloud, who suddenly found their links were broken. . Reports began to surface on March 24, and a day later, the iPad and iPhone maker told MacStories editor-in-chief Federico Viticci that the company was “working to restore previously shared shortcuts as quickly as possible.”. According to Detectify Knowledge Advisor and bug bounty hunter Frans Rosén, the root cause of the issue was a misconfiguration flaw he accidentally stumbled upon — and triggered — in Apple CloudKit.

Taylor Gulley with nVisium told Threatpost that he too agrees WhatsApp isn’t violating user privacy with its reporting feature.
