Inglis sworn in as first national cyber czar

therecord.media/inglis-sworn-in-as-first-national-cyber-czar/ Chris Inglis was sworn into office on Monday as the countrys first ever National Cyber Director, according to a White House spokesperson. Inglis, a former NSA deputy director, was unanimously confirmed by the Senate last month. He will advise President Joe Biden on digital issues, as well as play a key role in coordinating the federal governments response to hacks and other digital threats. The creation of the new White House office was a major policy recommendation of the Cyberspace Solarium Commission which Inglis served on and was enshrined into law in last years defense policy bill out of a bipartisan desire to see cybersecurity issues elevated within the executive branch and to have someone with the authority to coordinate the governments various digital missions.

Puhelimissa leviää huijaus, joka kehottaa avaamaan vastaajaviestin tulee tavallisista suomalaisista numeroista ja selvällä suomen kielellä

yle.fi/uutiset/3-12018913 Huijaustekstiviesti kehottaa vastaanottajaansa kuuntelemaan vastaajaviestin. Kyberturvallisuuskeskuksen mukaan kyse on alkukesän huijauskampanjan jatkeesta eli niin sanotusta flubot-ilmiöstä. Tekstiviestin linkkiä ei pidä avata. Huijausviestissä olevan linkin takaa asentuva ohjelma mahdollistaa myös huijausviestien lähettämisen saastuneen puhelimen kautta. Ja se juuri tekee tästä huijauskampanjasta tehokkaan, tietää Kyberturvallisuuskeskuksen tietoturva-asiantuntija Matias Mesiä. Myös:

KRP varoittaa huijauksesta: Virallisen oloinen viesti on ansa

www.is.fi/digitoday/art-2000008122901.html SUOMALAISILLE tulee nyt huijausviestejä kansainvälisen rikospoliisijärjestö Interpolin nimissä, kertoo Suomen keskusrikospoliisi (KRP). Huijari lähestyy Interpolin nimissä jo kertaalleen petoksen uhriksi joutunutta henkilöä ja tarjoaa tälle mahdollisuutta saada takaisin huijauksessa menettämänsä rahat. Viestit ovat tulleet sähköpostitse. KRP muistuttaa Twitterissä, ettei Interpol koskaan ota suoraan yhteyttä yksityishenkilöihin, tai kysele heidän tilitietojaan.

Maksufirma Klarnan kautta pystyy tilaamaan tavaraa toisen nimiin MOT:n testi osoittaa, kuinka pahasti ruotsalaisyhtiön tietoturva vuotaa

yle.fi/uutiset/3-12014974 Pohjoismaiden suurimpiin kuuluvan maksunvälitysyhtiö Klarnan järjestelmässä on vakava tietoturvaongelma, joka mahdollistaa yhtiön asiakkaiden tilien käyttämisen petoksiin, identiteettivarkauksiin ja kiusantekoon. Ongelma on ollut tiedossa useiden vuosien ajan. Heikon tietoturvan takia Klarnan palvelua on myös hyödynnetty toistuvasti rikosten tekemiseen. Näyttää aika pahalta. Tietosuoja on niin kriittinen asia, että ei pitäisi olla mahdollista tilata tavaroita toisen nimiin. Vaikka yrityksellä on jonkinlaista valvontaa, niin selvästikin se vuotaa, sanoo tietotekniikan asiantuntija ja tietokirjailija Petteri Järvinen.

Can Government Effectively Help Businesses Fight Cybercrime?

beta.darkreading.com/attacks-breaches/can-government-effectively-help-businesses-fight-cybercrime- When Team Cymru’s James Shank worked with the Ransomware Task Force to come up with the worst-case scenarios for a ransomware attack, the group focused heavily on impacts: How could attackers endanger people or cause significant damage to infrastructure?. However, the group also focused on vectors – including an exploitation chain that amplifies attacks by compromising the software supply chain, infecting managed service providers and propagating too quickly for defenders to react.. In short, the scenarios the group came up with looked very similar to the attack against managed service providers using a vulnerability in the Kaseya Virtual System Administrator (VSA) servers that happened on July 2.

How to Avoid Being Impacted by a Managed Service Provider (MSP) Breach

www.crowdstrike.com/blog/how-to-avoid-being-a-victim-of-a-msp-breach/ Managed service providers (MSPs) provide extremely important and valuable services by assisting organizations with information technology related tasks such as provisioning software or Active Directory accounts. Yet despite all of the benefits an MSP can provide, theres also an inherent risk: if an MSP is breached, its customers may also be. This scenario played out on the world stage July 2 with the REvil ransomware attack that targeted Kaseya a key software provider to MSPs and as a result, the MSPs themselves (fewer than 60 Kaseya customers) and just under 1,500 downstream companies, according to Kaseyas public statement at noon on July 6.

DNS Provider Hit With Outrageous Blocking Order Is Your Provider Next?

www.eff.org/deeplinks/2021/07/dns-provider-hit-outrageous-blocking-order-your-provider-next The seemingly endless battle against copyright infringement has caused plenty of collateral damage. But now that damages is reaching new levels, as copyright holders target providers of basic internet services. For example, Sony Music has persuaded a German court to order a Swiss domain name service (DNS) provider, Quad9, to block a site that simply indexes other sites suspected of copyright . Quad9 has no special relationships with any of the alleged infringers. It simply resolves domain names, conveying the public information of which web addresses direct to which server, on the public internet, like many other service providers.
