    Windowsin taustapalvelussa vakava haavoittuvuus – ”kytke pois käytöstä mahdollisimman pian”
    https://www.talouselama.fi/uutiset/windowsin-taustapalvelussa-vakava-haavoittuvuus-kytke-pois-kaytosta-mahdollisimman-pian/01b58cf7-6db2-482f-ad12-e4dd3a3fd0d8

    Windows Print Spoolerissa eli taustatulostuspalvelussa on todettu kriittinen haavoittuvuus, tiedottaa Kyberturvallisuuskeskus. Haavoittuvuus mahdollistaa esimerkiksi toimialueen haltuunoton ja ohjeet haavoittuvuuden hyväksikäytölle leviävät verkossa. Kyberturvallisuuskeskus pitääkin varmana, että ohjeet ovat jo päätyneet hyökkääjien käyttöön.

    Haavoittuvuus koskee laajasti Windows-versioita 7:stä 10:een ja Windows Server 2008:sta 2019:een. Tällä hetkellä ei ole tiedossa korjausvaihtoehtoja eikä haavoittuvuutta korjaavaa päivitystä ole vielä julkaistu. Kyberturvallisuuskeskuksen tiedotteen mukaan onkin tärkeää sammuttaa Print Spooler ja kytkeä se pois käytöstä.

    Haavoittuvuuden kerrotaan koskettavan organisaatioita ja näiden it-ylläpitäjiä. Yksityishenkilöiden tulee asentaa korjauspäivitys, kun se on julkaistu.

    Users advised to disable Print Spooler service on Windows.
    Researchers from a Hong Kong based security vendor accidentally published a proof-of-concept for a new and unpatched vulnerability affecting the Print Spooler service on all current versions of Windows, sparking concerns that ransomware criminals could add the bug to their arsenals.

    The exploit allows for both local privilege escalation and remote code execution and was published on Github by researchers from Sangfor ahead of their presentation at the Black Hat security conference.

    While Microsoft hasn’t rated the vulnerability, it allows attackers to remotely execute code with system-level privileges, which is as critical and problematic as you can get in Windows.

    Researchers at Sangfor published the PoC, in what appears to have been a mistake, or a miscommunication between the researchers and Microsoft. The test code was quickly deleted, but not before it had already been forked on GitHub.

    Swedish Coop supermarkets shut due to US ransomware cyber-attack
    https://www.bbc.com/news/technology-57707530

    Some 500 Coop supermarket stores in Sweden have been forced to close due to an ongoing “colossal” cyber-attack affecting organisations around the world.

    Coop Sweden says it closed more than half of its 800 stores on Friday after point-of-sale tills and self-service checkouts stopped working.

    The supermarket was not itself targeted by hackers – but is one of a growing number of organisations affected by an attack on a large software supplier the company uses indirectly.

    A spokeswoman for Coop Sweden told the BBC: “We first noticed problems in a small number of stores on Friday evening around 6:30pm so we closed those stores early. Then overnight we realised it was much bigger and we took the decision not to open most of our stores this morning so that our teams could work out how to fix it.

    Coop supermarket closes 500 stores after Kaseya ransomware attack
    https://thedigitalnews.org/2021/07/03/coop-supermarket-closes-500-stores-after-kaseya-ransomware-attack/

    Swedish supermarket chain Coop has shut down approximately 500 stores after they were affected by an REvil ransomware attack targeting managed service providers through a supply-chain attack.

    Last night, the supermarket chain closed its stores after the REvil ransomware gang targeted managed service providers (MSPs) and their customers in a massive supply-chain attack through Kaseya VSA, a remote patch management and monitoring uite.

    Soon after the attack, Coop posted a notice stating all of their stores except for five had been shut down after cash registers no longer functioned due to an “IT attack” on one of their suppliers.

    The Swedish supermarket chain Coop, one of the largest grocery stores in the country, had to close EVERY of its 800 branches on Saturday.

    Reason: a large-scale cyber attack! The attack blocked the cash register systems, said a company spokeswoman.

    The state railways and a pharmacy chain also reported disruptions. Defense Minister Peter Hultqvist (62) spoke of a very dangerous attack.

    “In another geopolitical situation, state actors could attack us in this way to cripple society and wreak havoc,” the minister said on television.

    “A huge and devastating attack”
    According to the TT news agency, the target of the attack in Sweden was software from the US provider Kaseya used in many companies. He had already stated on Friday that his VSA software might have been hacked.

    The tool is used by IT service providers to manage the computer systems of corporate customers. Kaseya recommended that VSA users shut down their servers immediately.

    According to the US security service provider Huntress, eight IT service providers and around 200 corporate customers were affected in the USA. “This is a huge and devastating attack on supply chains,” said Huntress manager John Hammond.

    Vulnerabilities in WAGO Devices Expose Industrial Firms to Remote Attacks
    https://www.securityweek.com/vulnerabilities-wago-devices-expose-industrial-firms-remote-attacks

    Several critical and high-severity vulnerabilities have been identified in programmable logic controller (PLC) and human-machine interface (HMI) products made by WAGO, a German company specializing in electrical connection and automation solutions.

    According to an advisory published this week by Germany’s CERT@VDE, which coordinates cybersecurity issues related to industrial automation, WAGO’s PFC100 and PFC200 PLCs, its Edge Controller product, and Touch Panel 600 HMIs are affected by four memory-related flaws impacting the iocheckd service I/O-Check.

    Critical vulnerabilities found in WAGO PLCsThe security holes can allow an attacker to cause a denial of service (DoS) condition and in some cases even execute arbitrary code. Each vulnerability can be exploited by sending specially crafted packets containing OS commands to the targeted device.

    Uri Katz, protocol researcher at industrial cybersecurity firm Claroty, has been credited for reporting the flaws to the vendor.

    “By chaining the shared memory overflow vulnerability (CVE-2021-34566) and the out-of-bound read vulnerability (CVE-2021-34567), we were able to create a full blown pre-auth remote code execution to take over any WAGO PFC100/200 device remotely,” Katz told SecurityWeek.

    Katz noted that there are a few hundred WAGO PFC devices exposed to the internet, which means they can be remotely targeted by malicious actors.

    REvil Used 0-Day in Kaseya Ransomware Attack, Demands $70 Million Ransom
    https://thehackernews.com/2021/07/revil-used-0-day-in-kaseya-ransomware.html?m=1

    Amidst the massive supply-chain ransomware attack that triggered an infection chain compromising thousands of businesses on Friday, new details have emerged about how the notorious Russia-linked REvil cybercrime gang may have pulled off the unprecedented hack.

    The Dutch Institute for Vulnerability Disclosure (DIVD) on Sunday revealed it had alerted Kaseya to a number of zero-day vulnerabilities in its VSA software (CVE-2021-30116) that it said were being exploited as a conduit to deploy ransomware. The non-profit entity said the company was in the process of resolving the issues as part of a coordinated vulnerability disclosure when the July 2 attacks took place.

    More specifics about the flaws were not shared, but DIVD chair Victor Gevers hinted that the zero-days are trivial to exploit. At least 1,000 businesses are said to have been affected by the attacks

    Kaseya VSA is a cloud-based IT management and remote monitoring solution for managed service providers (MSPs), offering a centralized console to monitor and manage endpoints, automate IT processes, deploy security patches, and control access via two-factor authentication.

    REvil Demands $70 Million Ransom
    Active since April 2019, REvil (aka Sodinokibi) is best known for extorting $11 million from the meat-processor JBS early last month, with the ransomware-as-a-service business accounting for about 4.6% of attacks on the public and private sectors in the first quarter of 2021.

    The group is now asking for a record $70 million ransom payment to publish a universal decryptor that can unlock all systems that have been crippled by file-encrypting ransomware.

    The REvil ransomware gang is asking for a $70 million ransom payment to publish a universal decryptor that can unlock all computers locked during the Kaseya incident that took place this past Friday, The Record has learned.

    In a message posted on their dark web blog, the REvil gang officially took credit for the attack for the first time and claimed they locked more than one million systems during the Kaseya incident.

    If honored, the demand would become the highest ransomware payment ever made.

    A Kaseya spokesperson was not on hand to comment if the company would be considering paying the REvil gang’s ransom demand.

    https://www.reuters.com/technology/biden-says-uncertain-who-is-behind-latest-ransomware-attack-2021-07-03/

    CENTRAL LAKE, Mich., July 3 (Reuters) – President Joe Biden said on Saturday he has directed U.S. intelligence agencies to investigate who was behind a sophisticated ransomware attack that hit hundreds of American businesses and led to suspicions of Russian gang involvement.

    Security firm Huntress Labs said on Friday it believed the Russia-linked REvil ransomware gang was to blame for the latest ransomware outbreak. Last month, the FBI blamed the same group for paralyzing meat packer JBS SA (JBSS3.SA).

    Biden, on a visit to Michigan to promote his vaccination program, was asked about the hack while shopping for pies at a cherry orchard market.

    Biden said “we’re not certain” who is behind the attack. “The initial thinking was it was not the Russian government but we’re not sure yet,” he said.
