Microsoft today released updates to plug nearly 120 security holes in Windows and supported software. Six of the vulnerabilities were publicly detailed already, potentially giving attackers a head start in figuring out how to exploit them in unpatched systems. More concerning, Microsoft warns that one of the flaws fixed this month is “wormable,” meaning no human interaction would be required for an attack to spread from one vulnerable Windows box to another.
On Aug. 13, 2020, someone uploaded a suspected malicious file to VirusTotal, a service that scans submitted files against more than five dozen antivirus and security products. Last month, Microsoft and FireEye identified that file as a newly-discovered fourth malware backdoor used in the sprawling SolarWinds supply chain hack. An analysis of the malicious file and other submissions by the same VirusTotal user suggest the account that initially flagged the backdoor as suspicious belongs to IT personnel at the National Telecommunications and Information Administration (NTIA), a division of the U.S. Commerce Department that handles telecommunications and Internet policy.
A week ago, KrebsOnSecurity broke the news that someone was attempting to disrupt the Trickbot botnet, a malware crime machine that has infected millions of computers and is often used to spread ransomware. A new report Friday says the coordinated attack was part of an operation carried out by the U.S. military’s Cyber Command.
Sources tell KrebsOnSecurity that Microsoft Corp. is slated to release a software update on Tuesday to fix an extraordinarily serious security vulnerability in a core cryptographic component present in all versions of Windows. Those sources say Microsoft has quietly shipped a patch for the bug to branches of the U.S. military and to other high-value customers/targets that manage key Internet infrastructure, and that those organizations have been asked to sign agreements preventing them from disclosing details of the flaw prior to Jan. 14, the first Patch Tuesday of 2020.
For almost the past month, key computer systems serving the government of Baltimore, Md. have been held hostage by a ransomware strain known as “Robbinhood.” Media publications have cited sources saying the Robbinhood version that hit Baltimore city computers was powered by “Eternal Blue,” a hacking tool developed by the U.S. National Security Agency (NSA) and leaked online in 2017. But new analysis suggests that while Eternal Blue could have been used to spread the infection, the Robbinhood malware itself contains no traces of it.
root9B, a company that many in the security industry considered little more than a big-name startup aimed at cashing in on the stock market’s insatiable appetite for cybersecurity firms, surprised no one this week when it announced it was ceasing operations at the end of the year.
Founded in 2011, Colorado Springs, Colo. based root9B Technologies touted itself as an IT security training firm staffed by an impressive list of ex-military leaders with many years of cybersecurity experience at the Department of Defense and National Security Agency (NSA). As it began to attract more attention from investors, root9B’s focus shifted to helping organizations hunt for cyber intruders within their networks.
WikiLeaks on Tuesday dropped one of its most explosive word bombs ever: A secret trove of documents apparently stolen from the U.S. Central Intelligence Agency (CIA) detailing methods of hacking everything from smart phones and TVs to compromising Internet routers and computers. KrebsOnSecurity is still digesting much of this fascinating data cache, but here are some first impressions based on what I’ve seen so far.
The U.S. Department of Homeland Security (DHS) has been quietly launching stealthy cyber attacks against a range of private U.S. companies — mostly banks and energy firms. These digital intrusion attempts, commissioned in advance by the private sector targets themselves, are part of a little-known program at DHS designed to help “critical infrastructure” companies shore up their computer and network defenses against real-world adversaries. And it’s all free of charge (well, on the U.S. taxpayer’s dime).
U.S. state and federal law enforcement officials appear poised to tap into public concern over the terror attacks in France last week to garner support for proposals that would fundamentally weaken the security of encryption technology used by U.S. corporations and citizens. Here’s a closer look at what’s going on, and why readers should be tuned in and asking questions.
I heard from many readers last week who were curious why I had not weighed in on the massive (and apparently still unfolding) data breach at the U.S. Office of Personnel Management (OPM). Turns out, the easiest way for a reporter to make sure everything hits the fan from a cybersecurity perspective is to take a two week vacation to the other end of the world. What follows is a timeline that helped me get my head on straight about the events the preceded this breach, followed by some analysis and links to other perspectives on the matter.
