A disproportionate number of Hafnium victims appear to have been small- to medium-sized businesses, which are more inclined to run a dedicated on-premises Exchange server for their email needs.
Microsoft-Owned GitHub Takes Down Exchange Server ExploitSecurity researchers warned this week that a full, public proof-of-concept exploit for recently-patched Microsoft Exchange Server vulnerabilities would further roil a hacking frenzy that had already escalated in recent days.
First spotted by security firm Volexity, a nation-state group that Microsoft calls Hafnium has been using multiple zero-day exploits —which attack previously unknown vulnerabilities in software—to break into Exchange Servers, which manage email clients including Outlook.
On top of all of that, says Check Point's head of vulnerability research Omri Herscovici, the Windows DNS bug can in some cases be exploited with no action on the part of the target user, creating a seamless and powerful attack.
On Thursday, the NSA issued an advisory that the Russian hacker group known as Sandworm , a unit of the GRU military intelligence agency, has been actively exploiting a known vulnerability in Exim, a commonly used mail transfer agent—an alternative to bigger players like Exchange and Sendmail—running on email servers around the world.
Another new feature it's testing, called "secure value recovery," would let you create an address book of your Signal contacts and store them on a Signal server, rather than simply depend on the contact list from your phone.
Trump is spouting while Ford and Tesla are shouting, but first: a cartoon about when data collection gets personal .Here's the news you need to know, in two minutes or less.
A light edit for coherence: Trump believes—and by all indications this is true belief, not posturing —that after the Democratic National Committee was hacked in 2016, the DNC gave a physical server to Ukrainian cybersecurity company CrowdStrike and refused to let the FBI see the evidence.
Like other prominent companies of its kind, CrowdStrike conducts digital forensic investigations, and defends its clients in part by removing a hacker's access to compromised accounts and devices.But when CrowdStrike or another firm investigates an incident, they typically don't physically remove a client's devices.
Zoom patched this DoS issue in a May update but for now is only adjusting its auto-join video settings, giving users a more prominent way of choosing whether their video feed automatically launches when they click a Zoom call link.
"Once the firmware is infected, there’s really no way to know if it is still infected or to recover from it." Karsten Nohl, Security Research Labs In their experiments, Eclypsium's researchers would rent an IBM bare metal cloud server, and then make a harmless alteration to its BMC's firmware, simply changing one bit in its code.
Ferguson, who spent decades as a software architect for companies including Dell and Microsoft and helped create IBM’s application server WebSphere, says this consumes more time than you might think. For the developer, the server is practically invisible.Ferguson says about 99 percent of Seeka TV's code runs on serverless platforms.
But the company later clarified that the compromised data included payment card expiration dates and Card Verification Value codes—the extra three or four-digit numbers that authenticate a card—even though British Airways has said it does not store CVVs. British Airways further noted that the breach only impacted customers who completed transactions during a specific timeframe—22:58 BST on August 21 through 21:45 BST on September 5.These details served as clues, leading analysts at RiskIQ and elsewhere to suspect that the British Airways hackers likely used a "cross-site scripting" attack, in which bad actors identify a poorly secured web page component and inject their own code into it to alter a victim site's behavior.
