A scientist claims to have developed an inexpensive system for using quantum computing to crack RSA, which is the world's most commonly used public key algorithm. If true, this would be a breakthrough that comes years before experts predicted. Now, they're asking for proof.
The volume of known ransomware attacks surged last month to record-breaking levels, with groups collectively listing 514 victims on their data-leak sites, security researchers report. In the lead: long-timer LockBit followed by newcomer LostTrust, with other new groups also having a notable impact.
The Clop ransomware operation's recent mass zero-day exploit of Progress Software's MOVEit secure managed file transfer software followed the criminals launching similar attacks against users of Accellion FTA, SolarWinds Serv-U and Fortra GoAnywhere.
The data leak and negotiation sites for the Ragnar Locker ransomware group went offline Thursday after an international law enforcement operation, backed by the FBI and police in Europe, seized its infrastructure. Whether the disruption spells the end for Ragnar Locker remains unclear.
How did Israeli intelligence fail to spot and stop the deadly assault on Saturday by Hamas militants? Experts suggest planners used offline tactics and extreme compartmentalization to prevent leaks and evade well-known Israeli cyberespionage and digital surveillance capabilities.
Trick question for CSOs: When does a security incident qualify as being a data breach? The answer is that it's "a very complicated question" best left to the legal team, said former Uber CSO Joe Sullivan, sharing lessons learned from the U.S. Department of Justice's case against him.
Hacktivists who hit healthcare or otherwise target civilians are violating international humanitarian law, warns the International Committee of the Red Cross. As many self-proclaimed hacktivists appear to be Russian government cutouts, will legal threats make them rethink their life choices?
A recent, brief disruption at Canadian airports is a reminder that Russia-aligned hacking groups' bark remains worse than their bite. Experts say these groups' impact largely remains minimal, which begs the question of how they disrupted arrival kiosks across Canadian airports.
Honeypot data collected by CISO Jesse La Grew highlights how attackers continue to target default usernames - including for SSH - together with weak passwords to gain brute force remote access to their targets. Here are essential username, password and remote service practices for combating such attacks.
Ransomware groups do whatever they can to pressure a victim into paying. Enter the likes of Ransomed, following in the footsteps of Alphv/BlackСat, NoEscape and Good Day-powered Cloak, all of which threaten victims with a world of General Data Protection Regulation violation pain unless they pay.
Has the cry of the Qakbot come to an end? While the pernicious, multifunction malware fell quiet last week thanks to Operation "Duck Hunt," lucrative cybercrime operations have a history of rebooting themselves. Rivals also offer ready alternatives to ransomware groups and other criminal users.
Cybersecurity doublespeak is never a good sign, especially when it comes in a letter this week addressed to half a million current and former employees of fast-fashion retailer Forever 21, warning them that their personal information was stolen in an eight-week breach discovered in March.
What's behind the profusion of reported attacks involving stolen or reused strains of ransomware? Blame a variety of factors, including law enforcement crackdowns, evolving ransomware business models and at least one case of a ransomware group leader with poor morale-building skills.
Ransomware and data exfiltration attacks continue to stick victims with serious bills to cover cleanup, legal and other resulting costs - to the tune of $10.8 million and counting for cloud computing giant Rackspace, for one. Rackspace was hit by the Play ransomware group last year.
Various "dark" generative artificial intelligence tools purportedly help criminals more quickly amass victims. Guess what? They've all gone bust, if they weren't simply outright scams - in part because legitimate tools can be "jailbroken" to achieve similar results. What are they really achieving?
