New research into the malware that set the stage for the megabreach at IT vendor SolarWinds shows the perpetrators spent months inside the company’s software development labs honing their attack before inserting malicious code into updates that SolarWinds then shipped to thousands of customers. More worrisome, the research suggests the insidious methods used by the intruders to subvert the company’s software development pipeline could be repurposed against many other major software providers.
A key malicious domain name used to control potentially thousands of computer systems compromised via the months-long breach at network monitoring software vendor SolarWinds was commandeered by security experts and used as a “killswitch” designed to turn the sprawling cybercrime operation against itself, KrebsOnSecurity has learned.
The still-unfolding breach at network management software firm SolarWinds may have resulted in malicious code being pushed to nearly 18,000 customers, the company said in a legal filing on Monday. Meanwhile, Microsoft should soon have some idea which and how many SolarWinds customers were affected, as it recently took possession of a key domain name used by the intruders to control infected systems.
The U.S. government — along with a number of leading security companies — recently warned about a series of highly complex and widespread attacks that allowed suspected Iranian hackers to siphon huge volumes of email passwords and other sensitive data from multiple governments and private companies. But to date, the specifics of exactly how that attack went down and who was hit have remained shrouded in secrecy.
This post seeks to document the extent of those attacks, and traces the origins of this overwhelmingly successful cyber espionage campaign back to a cascading series of breaches at key Internet infrastructure providers.
ATM “jackpotting” — a sophisticated crime in which thieves install malicious software and/or hardware at ATMs that forces the machines to spit out huge volumes of cash on demand — has long been a threat for banks in Europe and Asia, yet these attacks somehow have eluded U.S. ATM operators. But all that changed this week after the U.S. Secret Service quietly began warning financial institutions that jackpotting attacks have now been spotted targeting cash machines here in the United States.
How much would a cybercriminal, nation state or organized crime group pay for blueprints on how to exploit a serious, currently undocumented, unpatched vulnerability in all versions of Microsoft Windows? That price probably depends on the power of the exploit and what the market will bear at the time, but here’s a look at one convincing recent exploit sales thread from the cybercrime underworld where the current asking price for a Windows-wide bug that allegedly defeats all of Microsoft’s current security defenses is USD $90,000.
Premera Blue Cross, a major provider of health care services, disclosed today that an intrusion into its network may have resulted in the breach of financial and medical records of 11 million customers. Although the company isn’t saying so just yet, there are independent indicators that this intrusion is once again the work of state-sponsored espionage groups based in China.
It seems nearly every day we’re reading about Internet attacks aimed at knocking sites offline and breaking into networks, but it’s often difficult to visualize this type of activity. In this post, we’ll take a look at multiple services for tracking online attacks and attackers around the globe and in real-time.
Until today, Microsoft Windows users who’ve been unfortunate enough to have the personal files on their computer encrypted and held for ransom by a nasty strain of malware called CryptoLocker have been faced with a tough choice: Pay cybercrooks a ransom of a few hundred to several thousand dollars to unlock the files, or kiss those files goodbye forever. That changed this morning, when two security firms teamed up to launch a free new online service that can help victims unlock and recover files scrambled by the malware.
Microsoft is warning Internet Explorer users about active attacks that attempt to exploit a previously unknown security flaw in every supported version of IE. The vulnerability could be used to silently install malicious software without any help from users, save for perhaps merely browsing to a hacked or malicious site.
