Windows is in Moscow’s crosshairs, too
Before Russia invaded Ukraine this week, cyberattacks had been already beneath method. Not surprisingly, Windows techniques had been a typical goal.

Russia telegraphed its intentions to invade Ukraine nicely forward of this week’s assault by massing practically 200,000 troopers alongside Ukraine’s borders, and by Vladimir Putin’s more and more belligerent threats.
Behind the scenes, Russia was doing greater than that, together with harmful cyberattacks launched in opposition to Ukraine. And as is often the case in such assaults, Windows was the assault vector.
“We’ve observed destructive malware in systems belonging to several Ukrainian government agencies and organizations that work closely with the Ukrainian government, Tom Burt, Microsoft corporate vice president for customer security and trust, wrote in a blog post in mid-January. “The malware is disguised as ransomware but, if activated by the attacker, would render the infected computer system inoperable.” In a associated technical submit detailing how the malware works, Microsoft added: “These systems [under cyberattack] span multiple government, non-profit, and information technology organizations, all based in Ukraine.”
Notably, cash was not the item of the assaults. Instead, the attackers wished to destroy techniques and knowledge. And they succeeded. The malware attacked Windows-based techniques, overwriting Master Boot Records (MBR) with a ransom notice. Microsoft explains, “The MBR is the part of a hard drive that tells the computer how to load its operating system.”
After the an infection, “the malware executes when the associated device is powered down,” Microsoft stated. “Overwriting the MBR is atypical for cybercriminal ransomware. In reality, the ransomware note is a ruse and the malware destructs MBR and the contents of the files it targets.” (The malware assaults information in different methods as nicely.)
The assaults, in essence, had been the primary act of conflict in opposition to Ukraine; they possible presage extra to come back now that full-on conflict has begun.
Just earlier than Russia’s invasion, one other — probably extra harmful — cyberattack in opposition to Ukraine arose, in keeping with CIODive; that assault makes use of WatchGuard firewall home equipment to unfold malware. John Hultquist of Mandiant Threat Intelligence instructed CIODive, “In mild of the disaster in Ukraine, we’re very involved about this actor, who has surpassed all others we observe when it comes to the aggressive cyberattacks and knowledge operations they’ve performed. No different Russian menace actor has been so brazen and profitable in disrupting important infrastructure in Ukraine and elsewhere.”
The identical submit additionally warns a few new piece of malware focusing on Windows machines in Ukraine: HermeticWiper, whose sole objective is to destroy knowledge (additionally by focusing on their MBR).
There’s motive to consider extra is coming. “U.S. authorities have warned for months about the potential collateral damage of a Russian military incursion into Ukraine,” CIODive reported. The new cyber exercise might ricochet by way of multinational companies, provide chains and key infrastructure services, like transportation, vitality and healthcare.”
In an analogous vein, CybersecurityDive defined how cyberattacks can rapidly unfold and compound one another. “As international pressure grows over Russia’s conflict with Ukraine, major U.S. enterprises — particularly those operating critical infrastructure — are in the crosshairs of a nation-state military standoff that could easily spill onto the cyber terrain. Russia, largely isolated by the United States and key NATO allies, has demonstrated the will and ability to leverage a sophisticated arsenal of cyber capabilities from its military intelligence arm and a range of proxies from the country’s criminal underground.”
US authorities officers consider the US will probably be additionally focused. Earlier this month, ABC News cited a US Department of Homeland Security notice that warned: “We assess that Russia would contemplate initiating a cyberattack in opposition to the Homeland if it perceived a US or NATO response to a doable Russian invasion of Ukraine threatened its long-term nationwide safety.”
Given Putin’s obvious paranoia, there’s little doubt he believes US and NATO responses to the invasion — together with sanctions and different types of financial ache — will threaten Russia’s long-term nationwide safety. So, we are able to anticipate assaults to start at any level.
What does this imply for enterprise? Plenty. With Russian cyberattacks in opposition to the United States, even when your organization doesn’t function important infrastructure or have something to do with funds or safety, it is going to be within the crosshairs. When wide-ranging assaults are launched, they tackle a lifetime of their very own and goal any enterprise they will.
If corporations haven’t already undertaken stepped-up safety precautions, they’re already late. It’s time to harden your outer defenses. Patch each system that may be patched. Check Microsoft’s safety bulletins. Teach your employees how acknowledge email-borne and mobile-borne assaults.
And acknowledge that that is just the start. This conflict is simply the primary by which cyberattacks will accompany real-world harm. Given humankind’s penchant for warfare, extra wars will comply with. And Windows, due to its widespread use, will stay a key goal.
