For the past year, a site called Privnotes.com has been impersonating Privnote.com, a legitimate, free service that offers private, encrypted messages which self-destruct automatically after they are read. Until recently, I couldn’t quite work out what Privnotes was up to, but today it became crystal clear: Any messages containing bitcoin addresses will be automatically altered […]
Microsoft today released software patches to plug at least 129 security holes in its Windows operating systems and supported software, by some accounts a record number of fixes in one go for the software giant. None of the bugs addressed this month are known to have been exploited or detailed prior to today, but there […]
In late May, KrebsOnSecurity alerted numerous officials in Florence, Ala. that their information technology systems had been infiltrated by hackers who specialize in deploying ransomware. Nevertheless, on Friday, June 5, the intruders sprang their attack, deploying ransomware and demanding nearly $300,000 worth of bitcoin. City officials now say they plan to pay the ransom demand, […]
While it’s a well-known concept, we’ve recently seen the growing sophistication of phishing campaigns, making detecting phishing domains harder, increase of spear phishing in APT attacks, and the increasing use of customized, targeted emails that ensure these campaigns are more successful than ever. Even if almost everyone nowadays is aware of possibly getting phished, by […]
The co-owners of vDOS, a now-defunct service that for four years helped paying customers launch more than two million distributed denial-of-service (DDoS) attacks that knocked countless Internet users and websites offline, each have been sentenced to six months of community service by an Israeli court. vDOS as it existed on Sept. 8, 2016. A judge […]
Today we will deep dive into a related topic: DNS intelligence, its main concept, how important it is inside the cybersecurity world, and much more.

An exhaustive inquiry published today by a consortium of investigative journalists says a three-part series KrebsOnSecurity published in 2015 on a Romanian ATM skimming gang operating in Mexico’s top tourist destinations disrupted their highly profitable business, which raked in an estimated $1.2 billion and enjoyed the protection of top Mexican authorities.

The criminal group behind the REvil ransomware enterprise has begun auctioning off sensitive data stolen from companies hit by its malicious software. The move marks an escalation in tactics aimed at coercing victims to pay up — and publicly shaming those who don’t. But it may also signal that ransomware purveyors are searching for new […]
Some time ago, we talked about the cybersecurity skills gap, and the need to increase the cybersecurity workforce. We looked at how many cybersecurity positions are in high demand, how many of them are intermediate and advanced/managerial, and how security has now been ingrained into many IT roles that didn’t have these responsibilities in the […]
When law enforcement agencies tout their latest cybercriminal arrest, the defendant is often cast as a bravado outlaw engaged in sophisticated, lucrative, even exciting activity. But new research suggests that as cybercrime has become dominated by pay-for-service offerings, the vast majority of day-to-day activity needed to support these enterprises is in fact mind-numbingly boring and […]
The United Kingdom’s anti-cybercrime agency is running online ads aimed at young people who search the Web for services that enable computer crimes, specifically trojan horse programs and DDoS-for-hire services. The ad campaign follows a similar initiative launched in late 2017 that academics say measurably dampened demand for such services by explaining that their use […]
A group of Romanians operating an ATM company in Mexico and suspected of bribing technicians to install sophisticated Bluetooth-based skimmers in cash machines throughout several top Mexican tourist destinations have enjoyed legal protection from a top anti-corruption official in the Mexican attorney general’s office, according to a new complaint filed with the government’s internal affairs […]
The red team is considered the offensive side of the security. Red teams think like the attacker, they imitate real-world attacks and mimic adversary techniques and methods, uncover vulnerabilities in an organization’s infrastructure, launch exploits, and report on their findings. This is often a group of white hats — ethical hackers, offensive security professionals that […]
When a reliable method of scamming money out of people, companies or governments becomes widely known, underground forums and chat networks tend to light up with activity as more fraudsters pile on to claim their share. And that’s exactly what appears to be going on right now as multiple U.S. states struggle to combat a […]
In January 2019, dozens of media outlets raised the alarm about a new “megabreach” involving the release of some 773 million stolen usernames and passwords that was breathlessly labeled “the largest collection of stolen data in history.” A subsequent review by KrebsOnSecurity quickly determined the data was years old and merely a compilation of credentials […]
Almost daily now there is news about flaws in commercial software that lead to computers getting hacked and seeded with malware. But the reality is most malicious software also has its share of security holes that open the door for security researchers or ne’er-do-wells to liberate or else seize control over already-hacked systems. Here’s a […]
A well-organized Nigerian crime ring is exploiting the COVID-19 crisis by committing large-scale fraud against multiple state unemployment insurance programs, with potential losses in the hundreds of millions of dollars, according to a new alert issued by the U.S. Secret Service. A memo seen by KrebsOnSecurity that the Secret Service circulated to field offices around […]
Microsoft today issued software updates to plug at least 111 security holes in Windows and Windows-based programs. None of the vulnerabilities were labeled as being publicly exploited or detailed prior to today, but as always if you’re running Windows on any of your machines it’s time once again to prepare to get your patches on. […]
At one time, the waterfall model was used in software development: the process was fractionated into different linear phases, with phases having different tasks and objectives and only commencing once the previous phase was over. But to improve the delivery process, more efficient solutions had to be found. So after the waterfall came “agile”. Agile […]
Diebold Nixdorf, a major provider of automatic teller machines (ATMs) and payment technology to banks and retailers, recently suffered a ransomware attack that disrupted some operations.
