Biden administration prepares for a different kind of Iranian cyberthreat

As President Joe Biden wraps up his first week in the Oval Office, his national security team is still gearing up to face a myriad of looming digital security threats from Iran. Just over a year after the Trump administration used a drone strike to kill Qassem Soleimani, a top Iranian general, Iran is still weighing retaliatory action against the U.S., according to a recent Department of Defense assessment. That’s not the only threat the Biden administration may have to contend with — Iran carried out a number of online efforts meant to intimidate potential American voters prior to the presidential election, allegedly launched a hit list that identified U.S. election officials by name and was behind a reported effort to probe U.S. election websites. “From a geopolitical perspective — with the maximum pressure campaign, the assassination of Soleimani … they are a caged animal and I think they are very […] The post Biden administration prepares for a different kind of Iranian cyberthreat appeared first on CyberScoop.

Ransomware hackers launder bitcoin through just a handful of locations, researchers find

It’s starting to look like the ransomware industry is developing its own version of the 1%, where a small number of players enjoy most of the wealth.  Cybercrime investigators have suggested the spiraling trend of increasingly large ransomware cash demands and attack frequency is not the work of a large number of criminals, but instead the result of a specialized black market economy in which hackers will different skill-sets collaborate on a breach, then split the proceeds. A relatively small number of attack groups actually seem to make up most of that black market economy, offering their malicious software on a rental basis and then taking a sizable chunk of the profits and relying on money laundering to cover their tracks.  Researchers now are tracking more of this activity via the blockchain, an accessible ledger through which public bitcoin transactions are recorded. When ransomware victims pay attackers to unlock their systems to decrypt their […] The post Ransomware hackers launder bitcoin through just a handful of locations, researchers find appeared first on CyberScoop.

Mimecast confirms SolarWinds attackers breached security certificate, 'potentially exfiltrated' credentials

Email security firm Mimecast on Tuesday confirmed that the hackers behind the SolarWinds espionage campaign compromised a software certificate the firm uses to secure connections to Microsoft cloud services. The revelation underscores how deeply embedded the suspected Russian hackers have been in major technology companies as part of a campaign that has also breached multiple U.S. federal agencies. The hackers may have exfiltrated “certain encrypted service account credentials created by customers hosted” in the U.S. and the U.K., the new Mimecast statement reveals. The company said it wasn’t aware of the hackers decrypting or abusing any of the stolen credentials. But it still told its U.S. and U.K.-hosted customers to reset their credentials as a precaution. Mimecast, which says it has 39,000 customers around the world, offers an attractive target for spies looking to burrow into high-value organizations. A stolen software certificate of this type could allow an intruder to […] The post Mimecast confirms SolarWinds attackers breached security certificate, 'potentially exfiltrated' credentials appeared first on CyberScoop.

Signal vows to fight blockage in Iran amid newfound popularity

The Iranian government appears to have blocked Signal usage in recent days amid a newfound surge in popularity. Signal users in Iran began reporting issues connecting to the end-to-end encrypted chat application on Monday, according to Al Jazeera. The Open Observatory of Network Interference noted the apparent Signal blockage the same day. Some of the trouble began as early as Jan. 14 when Iran’s filtering committee labeled encrypted chat applications as “criminal content” and ordered them removed from local application stores. The government effort to restrict access to Signal’s encrypted messaging application comes in the wake of WhatsApp’s decision to announce an update to its privacy policy for business customers that would share their data with Facebook, WhatsApp’s parent company. The move was reportedly off-putting to so many users in Iran it appears to have pushed them to Signal, prompting the newfound attention from the Iranian government. Signal indicated on […] The post Signal vows to fight blockage in Iran amid newfound popularity appeared first on CyberScoop. (CyberScoop)
