Killnet DDoS attacks (yawn): Following Germany's decision to deliver Leopard 2 tanks to Ukraine, disguised intelligence operation "hacktivist group" Killnet launched DDoS attacks against German government websites and called it a great victory on their Telegram channel. Nobody cares about two-hour outages, Killnet. Give it a rest! Also, it's never Russia until Russia denies it.

CISA K12 resource: CISA has published a report to help K-12 institutions assess and protect their networks against cybersecurity threats.

NIST AI guidance: US NIST released its AI Risk Management Framework along with a companion playbook, explainer video, and an AI RMF Roadmap for organizations looking into working with AI toolsets.

Riot Games extorted: Riot Games says it received a ransom demand via email from the threat actor who hacked one of its employees and then gained access to one of its game development environments. Riot says the hacker is asking the company to pay a ransom demand, or they will release the source code for the League of Legends and Teamfight Tactics games and the source code of a legacy anti-cheat platform. The company says it does not intend to pay the ransom and expects the leaked source code to "increase the likelihood of new cheats emerging."

GoTo breach update: GoTo, the company that owns LastPass, updated a data breach notification it published last year when it said that some of its cloud hosting services were also impacted as part of the LastPass intrusion. GoTo says a recent investigation has found that the intruders managed to steal encrypted backups from its cloud storage. The backups contained data, including user information, for GoTo products such as Central, Pro, join.me, Hamachi, and RemotelyAnywhere. The company said the backups were encrypted, but the threat actor also stole an encryption key that would allow them to decrypt "a portion of the encrypted backups."

FanDuel breach: Sports-betting platform FanDuel emailed customers last week to let them know that their names and email addresses were stolen from the company's Mailchimp account. FanDuel joins e-commerce service WooCommerce as the second major company known to be affected by MailChimp's breach. Mailchimp, an email and newsletter platform, disclosed a security breach two weeks ago when it said that a threat actor hacked one of its employees and stole data from 133 Mailchimp customers.

Risky Biz News: Crypto-crime volumes went down in 2022, ransomware payments too

The reasons for this demise are layered and complex and not the simple and straightforward answer that we can usually find in most cases.

The war in Ukraine, the US Treasury's sanctions crackdown on cryptocurrency money launderers, major law enforcement busts, and the general collapse of the cryptocurrency ecosystem as a whole have all had their role in slowing down criminal operations.

For example, as Chainalysis experts put it—people are less likely to fall for scams if they think the entire ecosystem is down and aren't interested in making new investments.

Risky Biz News: Dark web mega-hack as Kraken takes over Solaris

Blockchain analysis firm Elliptic, which documented and confirmed the hack, says Solaris was one of the largest drug markets on the dark web last year, processing around $150 million in sales of drugs and other illegal goods and services in its short lifespan.

Elliptic says the market was closely associated with Killnet, a pro-Kremlin hacktivist group, although it's unclear if the group was also in charge of the market itself.

In December last year, Alex Holden, a US security researcher with Ukrainian roots, claimed to have hacked Solaris and stolen $25,000 worth of cryptocurrency, which he later donated to Ukrainian charity organizations.

Risky Business publishes sponsored product demos to YouTube. They're a great way for you to save the time and hassle of trying to actually get useful information out of security vendors. You can subscribe to our product demo page on YouTube here.

In our latest demo, Brett Winterford and Harish Chakravarthy demonstrate to host Patrick Grey how Okta can be used for passwordless authentication. These phishing resistant authentication flows — even if they are not rolled out to all users — can also be used as a high-quality signal of phishing attempts that can be used to trigger automated follow-on actions.

Russian cyber security firms have found that hackers have used the fear of "moblisation", i.e. conscription into Russia's war effort, to steal Telegram credentials in a successful large-scale campaign. The lure used was a link to a site that purportedly contained the list of people who could be drafted into the Russian army to fight in Ukraine this February.

Risky Biz News: Google Search and Ads have a major malware problem

Primarily because of its dominance in both online search and ads, Google hosts most of these campaigns.

The most annoying part of all of this is that Google's support and security teams appear to have been caught on the back foot and are completely unprepared for what's currently going on. Both security researchers and companies who had their brands abused say they've found it difficult to get Google to act and remove the malicious content from search results, a situation that invites more abuse for the foreseeable future.

Hacked Harmony funds move: North Korean hackers have moved and laundered more than $63.5 million worth of Ether from funds stolen in June last year from the Harmony bridge platform. The stolen funds were laundered and then deposited in accounts at cryptocurrency platforms Binance, Huobi, and OKX. Binance and Huobi froze a small portion of the funds, but the bulk is still under the hackers' control. The hack is believed to have been carried out by the Lazarus Group, a group of government-backed North Korean hackers.

Potocki says that since January 2022, MSI has been shipping MSI firmware updates that contain the new insecure Secure Boot defaults.

Tens of MSI motherboard models currently ship with these new settings for both Intel and AMD CPUs, impacting both Windows and Linux distros. A full list of impacted MSI motherboard models is available here.

While it may take some time for MSI to ship new firmware versions with fixed settings for its Secure Boot section, Potocki recommends that all MSI motherboard owners who rely on Secure Boot go into their UEFI/BIOS and change away from "Always Execute" to another policy.

Throughout the past year, the group has targeted countries and private companies that showed any kind of public support for Ukraine and its fight against Russia's invasion.

For example, the group targeted Finnish government websites shortly after the country announced its intention to join NATO and Lithuanian railways shortly after they blocked Russian goods transiting to Russia's Kaliningrad exclave.

Other targets included Ukrainian newspapers and schools, and entities across Norway, Estonia, and Poland.

SugarCRM released an official patch a week after public disclosure. The company said that all users who run on-premise servers of its SugarCRM Sell, Serve, Enterprise, Professional, and Ultimate services should apply the update to avoid future attacks.

The company says it has hired a forensics firm to investigate the one-week time window during which its cloud platform was exposed to possible attacks.

No CVE has been assigned to this issue yet.
