Nimelt ei ole e-hääl võrdne tavalise digiallkirjastatud failiga. E-hääl kasutab küll bdoci failiformaati, ent hääletamise puhul ei moodustata sellele ajatemplit ega tehta sertifikaadi kehtivuskontrolli hääletaja arvutis.

See leiab aset hoopis siis, kui hääl RIA ruumides asuvasse e-hääletamise serverisse jõuab. Viimane teeb omakorda päringu sertifitseerimiskeskusse, kuhu jääb maha logi. See lisab valimistele ühe astme turvalisust, sest urnis olevate häälte arv peab hiljem olema võrdne logis olevate päringutega. Sel viisil välistatakse, et keegi pahalane e-urni ise hääli juurde lisaks.

“Tähelepanek oli Boikol õige, et fail, mille ta bdocina masina kõhust välja tõmbab, selle allkiri ei valideeru. Aga see polegi kunagi mõeldud valideeruma. Süsteem on teisiti üles ehitatud,” ütleb Hanga.

Põhja-Inglismaal asuva SPAR kauplusteketis olevatest poodidest on üle 300 poe IT süsteemid küberrünnaku tõttu maas. Samuti on maas neile kaupa tarniva transpordifirma süsteemid.
More than 300 Spar stores close temporarily due to a cyber attack.

https://twitter.com/KiIntel/status/1467910930579304457
More than 300 branches of the convenience store chain Spar in the north of England have been hit by a cyberattack, forcing many of them to close.

The attack hit the company’s computer systems, causing a “total IT outage” that has prevented staff from taking card payments and locked them out of emails.

Some branches of the chain, one of the few places to buy groceries in many remote communities, are accepting cash but the rest have been forced to close entirely.

The IT outage first hit on Sunday and technicians worked through the night to try to fix the problems.

According to the Twitter account of one Spar branch on Monday afternoon, there was “no time set to be back online”.

Distribution partner James Hall & Company, which provides food to nearly 600 Spar sites across the north of England, has also been hit, and its website is down.

Pole ime, kui varsti tuleb teade, et tegelikult olid ründajad välisagendid "mingist" NATO küberkeskusest ja tegemist on aktiivse riigi vastase rünnakuga, mille tõrjumiseks oleks vaja kasutada surmavat jõudu!

Briri kaitseministeeriumi all olevat Ühendkuningriigi Kaitseakadeemia infosüsteeme tabas eelmisel aastal küberrünnak Hiinast või Venemaalt. Tõsised tagajärjed sellel pidid olema. Akadeemiat IT süsteeme kasutati edasitungiks Briti kaitseministeeriumi piiratud ligipääsuga süsteemide pihta.
A cyber attack – possibly by China or Russia – hit the academic arm of the UK's Ministry of Defence and had a "significant" impact, the officer in charge at the time has revealed.

A cyber attack – possibly by China or Russia – hit the academic arm of the UK's Ministry of Defence and had a "significant" impact, the officer in charge at the time has revealed.

Air Marshal Edward Stringer, who retired from the armed forces in August, said the "sophisticated" hack - discovered last March - prompted the Defence Academy to accelerate plans for its entire network to be rebuilt and made more resilient.

The targeting of an academic institution is a sign of how the frontline in modern warfare can be anywhere, the former director general of the academy told Sky News.

"The consequences for the operations were significant, but then manageable," Air Marshal Stringer said, in his first television interview since leaving the military.

He said he did not know whether criminals or a hostile state were responsible, but a primary concern had been if the hackers had tried to use the Defence Academy as a "backdoor" to penetrate much more secret parts of the MOD's IT systems.

USA käes olevast Venemaa kodanikust, kes on seotud 2016 aasta USA valimistesüsteemi häkkimisega, kirjutab Bloomberg. Tegu üsna Vene kaitseministeeriumi juhtkonnaga suhelnud tegelasega. Et on, mida Venemaal karta.
In the days before Christmas, U.S. officials in Boston unveiled insider trading charges against a Russian tech tycoon they had been pursuing for months. They accused Vladislav Klyushin, who’d been extradited from Switzerland on Dec. 18, of illegally making tens of millions of dollars trading on hacked corporate-earnings information.

Yet as authorities laid out their securities fraud case, a striking portrait of the detainee emerged: Klyushin was not only an accused insider trader, but a Kremlin insider. He ran an information technology company that works with the Russian government’s top echelons. Just 18 months earlier, Klyushin received a medal of honor from Russian President Vladimir Putin. The U.S. had, in its custody, the highest-level Kremlin insider handed to U.S. law enforcement in recent memory.

Klyushin’s cybersecurity work and Kremlin ties could make him a useful source of information for U.S. officials, according to several people familiar with Russian intelligence matters. Most critically, these people said, if he chooses to cooperate, he could provide Americans with their closest view yet of 2016 election manipulation.

According to people in Moscow who are close to the Kremlin and security services, Russian intelligence has concluded that Klyushin, 41, has access to documents relating to a Russian campaign to hack Democratic Party servers during the 2016 U.S. election. These documents, they say, establish the hacking was led by a team in Russia’s GRU military intelligence that U.S. cybersecurity companies have dubbed “Fancy Bear” or APT28. Such a cache would provide the U.S. for the first time with detailed documentary evidence of the alleged Russian efforts to influence the election, according to these people.

Klyushin’s path to the U.S. — his flight from Moscow via private jet, his arrest in Switzerland, and his wait in jail as Russia and the U.S. competed to win his extradition — is described in U.S., European and Swiss legal filings, as well as in accounts of more than a half-dozen people with knowledge of the matter who requested anonymity to speak about Moscow’s efforts and its causes for concern.

Two days later, a private jet flying from Moscow touched down at Sion Airport in southwestern Switzerland. Klyushin, his wife and five children stepped off the plane. A helicopter was standing by to whisk them to the exclusive ski resort of Zermatt, according to U.S. filings.

Shortly after leaving the plane, Klyushin was detained by Swiss police. He was taken hours later to a prison in nearby Sion.

His wife and kids continued to the ski resort along with a business partner and his daughter, according to two people familiar with the matter. The party returned to Moscow on March 29, after almost 10 days at a luxury chalet, these people said.

News of Klyushin’s detention provoked immediate action in Moscow: On April 7, Russia filed papers with Switzerland accusing Klyushin of fraud and seeking his extradition to face charges in his home country — a strategy the country has attempted to use in recent years when nationals have been accused abroad.

USA küberväejuhatus tegi esimese avaliku küberrünnaku eelmise aasta veebruari ja augustikuu vahemikus. Rünnakut vaatas pealt kaitseminister Austin. Info sellest tuli välja alles nüüd.

U.S. Cyber Command task force executed what is being described as its “first offensive cyber effect operation” against real-world cyber threats. While the exact nature of the operation and its target remains unknown, the event was significant enough for the U.S. Secretary of Defense to personally attend to watch the operation in action.

The operation was conducted between February and August 2021 by a task force consisting of personnel from the Maryland Air National Guard’s 175th Cyber Operations Group, the Delaware Air National Guard’s 166th Cyber Operations Squadron, U.S. Navy’s Cyber Strike Activity Sixty-Three, the U.S. Air Force’s 341st Cyber Operations Squadron, and the Air Force Reserve. The task force executed the operation from February to August last year, although the Air National Guard (ANG) just announced it this week.
Interestingly, Secretary of Defense Lloyd J. Austin III was on hand to personally witness the operation. “It was a massive milestone,” Maj. Bradford said, “so he wanted front row seats to see the action firsthand.”

ruger kirjutas:Öösel said siis pihta Ukraina valitsuse ja mitmete ministeeriumite IT süsteemid ning kodulehed
A hacker attack on the websites of the government and a number of ministries took place in Ukraine on the night of January 13-14.
The Ministry of Education and Science, the Ministry of Foreign Affairs, the State Emergency Service, the Cabinet of Ministers and the Actions are closed.

Ukraina teemas mainitud äsjastes küberrünnakutes kahtlustab Ukraina küberkaitse Valgevene riiklikke häkkereid (grupeering UNC1151).

Lisaks ukraina ja venekeelsetele tekstidele kasutati ka (ilmselt google translate abil) hädiselt tõlgitud poolakeelseid tekste.
The messages left on the Ukrainian websites on Friday were in three languages: Ukrainian, Russian and Polish. They referred to Volhynia and Eastern Galicia, where mass killings were carried out in Nazi German-occupied Poland by the Ukrainian Insurgent Army (UPA). The episode remains a point of contention between Poland and Ukraine.

Demedyuk suggested the hackers had used Google Translate for the Polish translation.

"It is obvious that they did not succeed in misleading anyone with this primitive method, but still this is evidence that the attackers 'played' on the Polish-Ukrainian relations (which are only getting stronger every day)," he said.

Ukraina IT süsteeme rünnati eesmärgiga need süsteemid hävitada ja kasutuskõlbmatuks teha. Ehk siis tavaliselt lunaraha juures antakse võimalus süsteemi taastada. Sellel juhtumil avastas Microsoft, et tegu oli IT süsteemide hävitamiseks mõeldud rünnakuga, mida poleks võimalik taastada. Kogu operatsioon on palju suurem, kui eelnevalt arvatud. Kindlasti on nakatunud süsteeme veel, mis võivad edasi nakatada alles jäänuid. Sisuliselt tahetakse Ukraina IT süsteemid hävitada.
Microsoft “assesses that the malware, which is designed to look like ransomware but lacking a ransom recovery mechanism, is intended to be destructive and designed to render targeted devices inoperable rather than to obtain a ransom.”

https://twitter.com/snlyngaas/status/14 ... 8233827330
Microsoft identified a unique destructive malware operated by an actor tracked as DEV-0586 targeting Ukrainian organizations. Observed activity, TTPs, and IOCs shared in this new MSTIC blog. We'll update the blog as our investigation unfolds.

https://twitter.com/MsftSecIntel/status ... 9454686215
This is far bigger than we thought and the attack now looks more like a preparation for a massive attack:
"Microsoft said on Sunday it continued to analyse the malware and warned it could render government digital infrastructure inoperable."

Spekulatsioon/Värske info.

Vahendan põnevat infot ja mõtteid NANOG listist (oluline kohtumispunkt erinevate võrguoperaatorite spetsialistidele):
Our transit traffic partners have reported multiple sub-sea cable
damages on the Atlantic route towards Europe and US east coast. Users
might face additional latency and occasional packet loss towards these
destinations.


Tõlge: Mitu läbi Atlanti jooksvat US-EU optilist kaablit on kehvas olekus.

Kodanik listis pakub huvitavat teooriat:
Multiple sub-sea cable problems referencing Europe and the US east coast…
Putin testing the waters for connectivity disruptions ahead of a Ukraine invasion? Where the US and NATO are the thorn in his side?


Ei mäleta millal viimati mitu ookeanialust samasuunalist kaablit samaaegselt pahasti oli.

Ja allveelaevadega optiliste kaablite näperdamisest on mujal piisavalt juttu olnud. Et kas nüüd siis päriselt? Elame-näeme ja ootame ametlikumat informatsiooni.
